'We can’t be the only ones,' says Sir Patrick Moore. 'I’m sure of it’

Following the discovery of an earth-type planet, legendary star-gazer Sir Patrick Moore and Brian May talk about whether there really is life out there
This week, astronomers discovered another planet: Alpha Centauri Bb. Don’t let the knotty name put you off, or the fact it would take 75,000 years in our fastest

rocket to reach it – it is the closest thing to a planet similar to earth. And the world’s astronomers are getting very excited.
One problem, however, is that the surface is thought to be far too hot for life, at about 1,500C. And right now, inside Sir Patrick Moore’s low-ceiling house in West

Sussex, the temperature feels about the same.
The swelter is caused by the crush of over-excited astronomers (is that an “observatory” of astronomers or a “nerdery” of star-gazers?), discussing this momentous

event. They have been joined by an assorted collection of admirers here to pay homage to King Patrick in his castle, from nine-year-old Jack, who has just started

using a telescope, to Brian May, the Queen guitarist and recipient of a PhD for his paper on zodiacal dust.
Ostensibly, the occasion is a book launch – May has collaborated with Moore and the astronomer Chris Lintott on a guide to the universe – but it feels like a very

sweaty, rather raucous fans’ convention.
“Patrick inspired us all,’’ May tells me. ''I used to beg to be able to stay up late enough to watch The Sky at Night and I was entranced by him. I was entranced by

the idea that there was a seemingly infinite universe out there, and I was entranced by the theme music as well.”
A seven-year-old May first watched Moore on television in the same week he was given his first guitar. For him, asteroids and rock music are connected.
Jon Culshaw, the impressionist, is another guest. “Patrick Moore was my first human impression,” he says. “I’d already cracked Woody Woodpecker, but then I moved

onto Patrick. He’s just marvellous.”
We are guzzling back Moore’s Malbec and munching his M&S nibbles in a sitting room crowded with mementoes from his 89 years on this planet. Around 300 shot glasses

line the shelves, while pictures of aliens drawn by his mother compete with various globes, a photograph of him at the piano accompanying Albert Einstein, and signed

pictures of assorted astronauts. Moore reckons he is the only person to have met the first man to fly, Orville Wright, the first man in space, Yuri Gagarin, and the

first man to a walk on the moon, Neil Armstrong.
He has outlived them all. Just. Sadly, he is becoming too frail to party like he used to. And while the temperature continues to rise in the sitting room, a queue is

forming outside the study, where Moore is ensconced. Acolytes are allowed in one or two at a time to touch his hem and have him sign their copy of The Cosmic Tourist.
The book, a coffee-table tome of the top 100 sights in the universe, with sumptuous photographs of distant stars and exploding supernovae, is the second venture Moore

has undertaken with May and Lintott (the latter was Moore’s co-presenter of the BBC’s The Sky at Night and the only professional astronomer among the three). They

are an unlikely trio: May, the badger-loving rock star with Isaac Newton hair; Moore, huge in body and mind despite being in a wheelchair and very frail in speech; and

Lintott, who is like a schoolboy hanging out with his heroes.
Lintott is now a tutor at New College, Oxford specialising in how galaxies are formed. He, too, credits Moore with starting it all.
“It was my first year at secondary school, Torquay Boys Grammar, and he came to give a lecture on the outer planets. And I don’t remember anything that he said

except for the last few sentences.” He puts on his best Moore rapid-gun, Fifties-type, radio-announcer voice: “?'I’ve told you about the outer planets, but the

truth is we don’t know much about the outer planets and if I come back in 10 years, it will be all different.’ And that was the first time I’d ever heard an adult

say we don’t know everything. That was the moment I realised there was science to be done.”
Lintott has been a Moore groupie ever since. Indeed, as an undergraduate, he produced Moore’s “comic opera” (in which Galileo marries the pope). “It was a huge

success,” he insists, laughing. “A sell-out, I’ll have you know.”
He is undoubtedly the jolliest of the three. Brian May cuts a rather pensive figure. This may have something to do with the fact he has spent the last hour up in

Patrick’s bedroom on the phone to the EU agriculture department, as part of his high-profile quest to stop the Government’s proposed badger cull.
May, who puts on a good-natured act of mock horror when I announce I am from the farmer-friendly Daily Telegraph, says he has hardly slept in the last fortnight as he

has shuttled from one meeting to another in Westminster.
His friendship with Moore was formed over Venus and Jupiter, but they also bonded over a mutual love of furry woodland creatures. Moore is a passionate anti-hunt

campaigner. What is it about astronomy and animals?
“Contrary to what Ptolemy thought, man is not the centre of the universe,” May begins earnestly. “The earth is not the centre of the universe; it’s not even the

centre of the solar system. The solar system isn’t the centre of the galaxy, and the galaxy is not the centre of the observable universe. Man is very small and I

think astronomers understand that very well. I don’t think I have ever met an astronomer who didn’t have an empathy for animals.”
Yes, but badgers are spreading TB to cattle; don’t cows get a look-in, too? Here, he fires off a rather dramatic argument against the cull.
“You know we had an Aids epidemic – or so it seemed – in Britain in the Eighties. A number of people had Aids and we were all frightened we were going to get it. So

just supposing the Government had said, 'Let’s just kill 70 per cent of people who have Aids’. But it is worse than that, because what they are doing with the

badgers is, 'No, let’s kill 70 per cent of all people and see if that improves the situation’. It’s so illogical it actually boggles the mind.”
To me, it is, frankly, a mind-boggling analogy, but he speaks in such a polite, thoughtful tone it is impossible to doubt his sincerity. Does Lintott feel the same?
“All animals are lovely,” he says diplomatically, while making it clear he isn’t going to be picking up a placard any time soon.
Anyway, for him, the most mind-boggling thought of all is that there just might be life out there, following Alpha Centauri Bb’s discovery.
“I would bet you a month’s salary there are more planets in that system.” And what would you bet that some of those planets are in the so-called Goldilocks zone –

not too hot, not too cold, where bacteria or plants could survive? “You can have a day’s salary that there are planets with conditions to sustain life.”
Moore chips in, saying: “We can’t be the single one. I am sure of it, but I can’t prove it.”
And, who knows, if we could invent a powerful enough telescope, we might even be able to detect some badgers gallivanting four million light years away. It would

certainly make May very happy.

Conjoined twins Rosie and Ruby successfully separated

When doctors discovered that Angela Formosa was carrying conjoined twins, she was warned that they may not survive the pregnancy.
However, against the odds, identical little girls Rosie and Ruby were born alive, joined at the abdomen and sharing part of an intestine.
Just a day after they were born the twins underwent emergency surgery to separate them.
The surgery at London's Great Ormond Street Hospital (GOSH) took five hours and involved a team of 15 doctors and nurses on July 27.
It was a great success and doctors say the girls, who are now 12 weeks old, can look forward to a normal happy life.
Mrs Formosa, from Bexleyheath, Kent, said she was "incredibly grateful" to the GOSH staff.
"What they have done for my two girls is amazing," she said.
"When I was pregnant they were saying that the survival chances were quite low. For them to have been operated on and doing so well - it is amazing."
The mother-of-three said she had a "textbook" pregnancy with her first daughter Lily, now aged five, so finding out the twins were joined was a "shock".
"At an early pregnancy scan they said the twins looked very close together so I went to King's College for another scan," the 32-year-old said.
"Between 16 and 20 weeks we found out that they were joined - I didn't know what to think, I was shocked and I felt sad.
"We didn't know what to expect until they were born - the doctors could not tell where they were connected.
"They decided to deliver them early at 34 weeks. I went into University College Hospital and had the C section and the doctors decided that the girls should go for

their operation quite soon, within a couple of hours they had been taken to GOSH.
"I stayed at UCH overnight then discharged myself the next day so I could be with the girls."
Mrs Formosa said that she and her taxi driver husband Daniel, 36, were "happy and relieved" to have the girls at home.
She said: "They are really well, they are putting on weight.
"They are normal bubbly babies who are starting to smile and cry when they want something."
The girls were operated by a team of specialists led by paediatric surgeon Professor Agostino Pierro.
"In this case, the twins were joined by the abdomen at the level of the umbilicus and shared part of the intestine," he said.
"The operation to separate the twins had to be performed as an emergency because of an intestinal blockage.
"We are delighted with the outcome of the operation. The babies will need further treatment in the future, but we expect that they will both be able to lead happy and

normal lives."
Great Ormond Street Hospital is the most experienced centre in the world in the care and separation of conjoined twins, having cared for 32 cases in all, including 25

separations.
Last year surgeons successfully separated Rital and Ritag Gaboura, from Sudan, who were joined at the head - the rarest, most complex and life threatening forms of the

condition.
Overall the survival rate for twins whose operation can be planned in advance and done at a time when they are well and stable is 80 per cent.
The latest operation had to be performed urgently as Rosie and Ruby shared an intestine which had become blocked.
Professor Agostino Pierro said the twins were given a good chance of survival because of the way they were joined.
He said: “The separation of Ruby and Rosie was a complex procedure but was less difficult to achieve than some of the other conjoined twins separations we have

successfully carried out at Great Ormond Street Hospital.
“The joining was not as extensive as some of the other twins that we’ve separated. Nevertheless, the challenges with this specific separation were the joining of the

intestine and the intestinal obstruction as well as the unclear anatomy in spite of several pre-operative scans.
“Any separation of conjoined twins requires expertise, which I and the team have developed over many years in this hospital. The separation of conjoined twins can

involve most of our paediatric specialties, such as general surgery, urology, anaesthesia, intensive care, radiology, orthopaedics, neurosurgery, plastic surgery,

cardiac surgery, nephrology, respiratory medicine, microbiology and nursing staff.”
They will probably need further surgery in six months time and maybe another operation some time after that, but he said they could expect to lead normal lives.
Thw twins were in intensive care for just six days and were able to go home three weeks later.
Conjoined twins are very rare, occuring in one in every 50,000 pregnancies, however 60 per cent die before birth.
Only one in every 250,000 live births is to conjoined twins.

ZTE's new smartphone will work in all European LTE frequency bands

The ZTE Grand Era LTE is the newest addition to the company's Grand series, and is compatible with LTE networks across Europe, the company said on Monday.
At present, European LTE networks operate mainly using the 800MHz, 1800MHz and 2600MHz and frequency bands and, unlike Apple's iPhone 5, ZTE's Grand Era LTE can communicate using all three. The iPhone 5, on the other hand, does not work on the 800MHz and 2600MHz bands, leaving it compatible with LTE networks in only a handful of European countries, including those in the U.K. and Germany.
Other smartphones that also support all three bands include the Galaxy S III LTE from Samsung Electronics and Nokia's upcoming Lumia 920. But Europe is still trailing the U.S. when it comes to the number of LTE devices users can choose from.
Supporting all three LTE bands in use in Europe doesn't just improve geographic coverage, but can also improve overall performance when an operator uses more than one of them. The 800MHz band's characteristics, for instance, make it better at penetrating walls, while the 2600MHz band has more spectrum available to operators, which allows them to offer higher speeds. If both phone and operator support both bands, the user gets the best of both.
The 1800MHz band lies somewhere in between, with better indoor coverage than 2600MHz. It can also offer higher speeds if operators have access to 20MHz of spectrum for both download and upload traffic, which is the case for Deutsche Telekom in Germany but not for EE in the U.K.
The Grand Era LTE is a mid-range smartphone that is based on Android 4.0. It is powered by a 1.5GHz dual-core processor and has a 4.5-inch display with a 1280 by 720 pixel resolution and Gorilla Glass protection.
The phone is 8.5 millimeters thick, compared to 7.6mm for the iPhone 5. It also has an 8-megapixel camera and 16GB of embedded memory.
Pricing was not announced, but the Grand Era LTE is due to launch in Europe by the end of the year and in the Middle East and North Africa in the first half of next year.
In general, LTE continues to make strides; there are now more than 100 commercial networks across the world, according to industry organization GSA (Global mobile Suppliers Association). The GSA also forecasts that 159 commercial networks will be up and running by end 2012.

Newly discovered 'super-Earth' is made of diamonds, say scientists

It may not twinkle like a star but it is still a diamond in the sky according to astronomers who have found a rocky planet similar to Earth but made of the precious

gemstone.

The diamond planet is one of five "exoplanets" orbiting a distant star called 55 Cancri, some 40 light years away from our own Solar System but still visible to the

naked eye in the constellation of Cancer.

Scientists said that an analysis of the chemical composition of the planet based on measurements of its mass and radius, combined with computer modelling, suggests its

outer crust is largely composed of solid carbon crystals.

"This is the first glimpse of a rocky world with a fundamentally different chemistry from Earth. The surface of this planet is likely covered in graphite and diamond

rather than water and granite," said Nikku Madhusudhan of Yale University.

The planet's radius is twice that of Earth's, but its mass it eight times greater, making it a "superearth". It orbits its own star at hyper speed, with a year lasting

just 18 hours, and surface temperatures reaching a blistering 2,150C with no possibility of liquid water and therefore life.

The study, published in the Astrophysical Journal Letters, estimates that at least a third of the planet could be composed of diamond, with the rest made up of

graphite, iron, silicon carbide and possibly silicates.

"By contrast, Earth's interior is rich in oxygen, but extremely poor in carbon, less than one part in a thousand by mass," said Kanani Lee, a geologist at Yale and

co-author of the study.

It is the first time that astronomers have identified a diamond planet, although they have theorised about their existence for some time.

David Spergel, professor of astronomy at Yale, said: "Stars are simple. Given a star's mass and age, you know its basic structure and history. Planets are much more

complex. This diamond-rich super-Earth is likely [to be] just one example of the rich sets of discoveries that await us as we begin to explore planets around nearby

stars."

Mice learn songs in similar way to humans and birds

They found that when male mice were housed together they learned to match the pitch of their songs to each other.

Mice also share some behavioural and brain mechanisms involved in vocal learning with songbirds and humans, say the researchers.

But some scientists are sceptical, saying the evidence doesn't support the claim.

Details of the study are published in the Journal, Plos One.

Previous research in this field has shown that male mice can sing complex songs when exposed to females and these play an important part in courtship.

These murine serenades are ultrasonic. At between 50 and 100KHz, they are far above the hearing range of humans. When processed to make them audible to humans, they sound like a series of plaintive whistles.

Rare skill
It has long been assumed that mice were incapable of modifying the sequence or the pitch of these sounds. This ability, called vocal learning, is rare in the natural world. It is restricted to some birds such as parrots and song birds along with whales, dolphins, sea lions, bats and elephants.

But in these experiments, researchers from Duke University in North Carolina say they found that mice have both the brain circuits and the behavioural attributes consistent with vocal learning.

Dr Erich Jarvis, who oversaw the study, told BBC News that it had changed his understanding of the way mice make sound.

"In mice we find that the pathways that are at least modulating these vocalisations are in the forebrain, in places where you actually find them in humans," he said.

He says the study does not have clear evidence that mice have the very same vocal abilities as birds and humans. He believes there is a spectrum where different species have vocal skills to different degrees.

"We think mice are intermediate in this ability between a chicken and a song bird or even a non human primate and a human," he said.

Living in harmony
When male mice with different vocal pitches were housed together, the team found that the pitch of their songs gradually converged over a period of eight weeks.

Dr Jarvis argues that this is an important development: "When we put a female in the cage with two males, we then found that one male would change his pitch to match the other. It was usually the smaller animal changing the pitch to match the larger animal," he said.

But others are less certain. Dr Kurt Hammerschmidt, an expert in vocal communication at the German Primate Centre in Goettingen, cast doubt on the study's claim about the vocal behaviour of male mice.

"The pitch convergence story is less convincing," he says.

But Erich Jarvis refutes this, saying the scepticism is unfounded.

"His complaint was that we don't have enough animals, but we found this in 12 mouse pairs and in every single pair... at least in our eyes it's quite reliable and statistically significant," he said.

Children under three should be banned from watching TV to improve health and wellbeing

Parents need to drastically cut the number of hours children spend watching television, while under threes should be stopped from watching altogether, a leading psychologist has warned.
Limiting the amount of time youngsters are sat in front of a screen could have significant advantages for their health, development and wellbeing, according to Dr Aric Sigman.
By the age of seven, a child born today will have spent a full year glued to screens and over the course of childhood youngsters spend more time watching TV than in school.
The population's vast use of games consoles, tablet computers, televisions, smart phones and laptops has been linked to obesity problems and an increased risk of cardiovascular disease and Type 2 diabetes - with the average child exposed to five different screens in each household.
Writing in the influential medical journey Archives Of Disease In Childhood, Dr Sigman said such extensive use could also lead to attention problems and other psychological difficulties.
Reducing total daily screen time for children, and delaying the age at which they start, could provide significant advantages for their health and wellbeing,' he writes.
‘While many questions remain regarding the precise nature of the association between screen time and adverse outcomes, the advice from a growing number of both researchers and other medical associations and government health departments elsewhere is becoming unequivocal: reduce screen time.’
The amount of time spent in front of a screen could also adversely affect children's social relationships, he added.
He said many parents use the devices as ‘electronic babysitters’ as a means to occupy their children.
‘Screen time appears to have created the three-parent family,’ he added.
There are emerging concerns about the amount of time children spend watching 3D televisions and consoles - saying such devices could affect the development of the child's depth perception.
Dr Sigman - who is also a child health expert - has made a raft of suggestions for children's screen consumption including delaying the age children start using screens to at least three.
Children aged between three and seven should be limited to half-an-hour to an hour of screen time each day, he said.
Those aged seven to 12 should spend just one hour in front of screens.
Children aged 12 to 15 should have a maximum of 1.5 hours in front of screens and those aged 16 and over should spend just two hours, he recommends.
He concluded: ‘As health risks are reported to occur beyond exposure of two hours of screen time per day, although the average child is exposed to three times this amount, a robust initiative to encourage a reduction in daily recreational screen time could lead to significant improvements in child health and development.
‘Britain and European medical establishments should consider screen time as a separate entity from sedentary behaviour, and offer an advisory on the average number of hours per day young children, in particular, are viewing screen media, and the age at which they start.’

First images of particle jets at edge of a supermassive black hole

Supermassive black holes appear to occupy the center of almost all galaxies. When they are actively swallowing matter, these black holes can power energetic jets that shine brighter than the entire rest of the galaxy, and can shoot matter free of it.  Despite the mass and energy involved, however, the origin of these jets has been extremely hard to image, both because they're relatively compact, and because they're situated in the crowded centers of distant galaxies.

Now, however, researchers are putting together an array of telescopes stretched across the globe with the specific goal of imaging the environment near these supermassive black holes. The team behind the Event Horizon Telescope has now used it to image the black hole at the center of the M87 galaxy, and returned the first details of the disk of matter that is being sucked into that galaxy's central black hole.

It's difficult to imagine the environment near a supermassive black hole. These objects are typically over a million times the mass of our Sun, but all of that matter is crammed into a space that may only be a fraction of the Sun's radius. Any matter falling into one piles up into an orbiting disk of material (called an accretion disk) that increases in density and energy as you get closer to black hole. Any matter that crosses a critical point, however, rapidly spirals inward to the black hole itself.  The inner area of the disk is so energetic that it actually sends matter away from the black hole in a wind of particles.

But that's not the most energetic part. Even further inward, the intense magnetic field lines sometimes cross the event horizon of the black hole itself, propelling intense beams of charged particles away from the black hole. These jets interact with the wind of particles coming from the accretion disk, which focuses them into narrow beams that move at nearly the speed of light. These have so much energy that they are (in some cases) able to propel particles for hundreds of thousands of light years, sending them entirely out of the galaxy, where the particles eventually slow by interacting with the intergalactic medium.

Or that's what theoretical considerations seem to tell us. To actually image any of this, however, has been a serious challenge. It's what the Event Horizon Telescope was intended to solve. In a paper in this week's edition of Science, four of the telescope's instruments were pointed towards the center of M87: Hawaii's James Clerk Maxwell Telescope, the Submillimeter Telescope in Arizona, and two telescopes at CARMA in California. By carefully timing the incoming signals at each of these scopes (and using the two neighboring instruments in California to refine the signal), the researchers could turn these distant instruments into a single, giant telescope, one that could resolve details of the environment near the central black hole.

This system managed to image the area around the black hole down to a resolution on the scale of the Schwarzchild radius. And they were able to spot that the base of the high-energy jets is only a few times the size of the black hole itself (5.5 times the Schwarzchild radius), which "is consistent with scales on which energy is extracted from the black hole and accretion disk to feed the jet."

This also tells us something about the accretion disk. If the disk and black hole were rotating in opposite directions, the inner edge of the disk would be much further from the black hole itself than if they were rotating in the same direction. The size of the jets seen here is too small to arise from a system where the two bodies are rotating in opposite directions, so we can conclude that the disk is following the rotation of the black hole it orbits.
Even if the Event Horizon Telescope is improved, we're not likely to get a better picture of the black hole's environment, because the model built from the observation runs up against limits that arise from our uncertainties regarding the distance to M87 and the mass of the black hole within it. But the authors hope to be able to use the telescope to continue observations over longer periods of time, since the accretion disk probably contains an uneven distribution of matter, which could create periodic irregularities in the output.

Plus, eventually, they hope to turn the telescope on our own galaxy's black hole. It's not as active as M87's, but it still seems to be swallowing enough matter to make checking it out at high resolution worth our while.

Whale beaches on storm-wracked Northumberland coast

While the north of England turns its mind to clearing up following the two-day deluge – coverage here - another possible victim of the weather has turned up on the Northumberland coast.

It is an eight-metre-long minke whale which has beached itself at Druridge Bay, scene of last weekend's mass naked swim which you can read about here or watch on a video clip here.

The whale was first reported earlier this morning by a walker who 'phoned the north east Coastguard. They sent divers and alerted the fire service for possible heavy lifting later in the day. A vet is treating the whale which is described as dehydrated, under-nourished and much thinner than normal for a creature of its size and estimated age.

Richard Stewart, the watch officer at Humber Coastguard says:

This morning at about 7.50am we received a call from a member of the public saying that she had come across a beached whale on Druridge Bay. Coastguard colleagues, divers, the fire brigade and vet are all there now. The whale is still alive.

Minke whales off the UK tend to be solitary or limited to small groups of two or three, usually staying within 40 miles (64.5kms) of the coast. Beaching is unusual but can happen in unusual weather conditions or when a whale becomes ill and disorientated or too weak to resist tidal movement.

Steven Marsh, operations manager at British Divers Marine Life Rescue based in Uckfield Sussex says:

This one has stopped eating for whatever reason - maybe it has a disease or parasite, or something in its mouth that causes problems with feeding. We won't know how best to care for it until the vet gives their assessment.

If the whale is thought capable of surviving, it will be relaunched on a PVC mat attached to pontoons for the ebbing tide to take it our to sea. But Marsh adds:

It hasn't got any muscle on it at all, and the last thing we want to do is put an animal back in the sea that's likely to suffer and come back again.

There's more about finding stranded marine mammals here and the long and complex history of whale beachings here. Animals incapable of reasonably rapid relaunch are treated humanely but are seldom capable of surviving.

Update 11.30am: Marsh says that sadly the whale is too sick to be relaunched:

They're attempting to euthanise it now using a drug that will put it to sleep. It was in a very poor shape and we don't re-float animals that would die if they were released out to sea.

The storm hasn't killed this whale, but it may have caused it to wash up on the beach. If there is a storm, sick whales are less able to fight it and are more likely to be swept on to beaches.

Humongous, gassy halo found surrounding Milky Way

Our galaxy — and the nearby Large and Small Magellanic Clouds as well — appears to be surrounded by an enormous halo of hot gas, several hundred times hotter than the surface of the Sun and with an equivalent mass of up to 60 billion Suns, suggesting that other galaxies may be similarly encompassed and providing a possible clue to the mystery of the galaxy’s missing baryons — a.k.a., dark matter.
The findings were reported today by a research team using data from NASA’s Chandra X-ray Observatory.

In the artist’s rendering above our Milky Way galaxy is seen at the center of a cloud of hot gas. This cloud has been detected in measurements made with Chandra as well as with the European Space Agency’s XMM-Newton space observatory and Japan’s Suzaku satellite. The illustration shows it to be nearly 300,000 light-years across — and it may actually be even bigger than that.

Are you scientifically literate? Take our quiz

While observing bright x-ray sources hundreds of millions of light-years distant, the researchers found that oxygen ions in the immediate vicinity of our galaxy were “selectively absorbing” some of the x-rays. They were then able to measure the temperature of the halo of gas responsible for the absorption.

The scientists determined the temperature of the halo is between 1 million and 2.5 million kelvins — a few hundred times hotter than the surface of the Sun.

But even with an estimated mass anywhere between 10 billion and 60 billion Suns, the density of the halo at that scale is still so low that any similar structure around other galaxies would escape detection. Still, the presence of such a large halo of hot gas, if confirmed, could reveal where the missing baryonic matter in our galaxy has been hiding — and possibly hint at the true nature of dark matter throughout the Universe.

Read: Dark Matter Filaments Bind Galaxies Together

Even though previous studies have indicated halos of warm gas existing around our galaxy as well as others, this new research shows a much hotter, much more massive halo than ever detected.

“Our work shows that, for reasonable values of parameters and with reasonable assumptions, the Chandra observations imply a huge reservoir of hot gas around the Milky Way,” said study co-author Smita Mathur of Ohio State University in Columbus. “It may extend for a few hundred thousand light-years around the Milky Way or it may extend farther into the surrounding local group of galaxies. Either way, its mass appears to be very large.”

Probe into cause of Fife mass whale stranding continues

The environment secretary said he wanted the report results "as soon as possible"
Scientists are continuing their investigations into what caused a group of whales to die in a mass stranding on the Fife coast.

Twenty-two pilot whales died when they became beached between Pittenweem and Anstruther earlier this month.

Researchers at the Scottish Agricultural College (SAC) have been examining the carcasses.

Environment Secretary Richard Lochhead has requested a full report into the incidents "as soon as possible".

In a separate incident, a dead sei whale was also found on a beach at Eliot near Arbroath last week.

Initial results
Mr Lochhead said: "It is deeply distressing when we hear reports of whales dying, particularly mass stranding incidents such as we saw earlier this month in Fife.

"The reasons why whale strandings take place, be it natural causes or linked to human activities, are not known.

"The initial findings do not point towards any obvious health problems, however I hope that by examining and testing the carcasses, SAC will be able to shed light on

this concerning issue."

Following the mass stranding of the pilot whales, each of them approximately 20ft (6m) long, ten others were refloated after being kept alive by vets from British

Divers and Marine Life Rescue.

There are many reasons why whales come close to shore and strand, according to SAC veterinary investigation officer Andrew Brownlow.

He said: "Initial results on the pilot whales suggest most were healthy.

"Strandings are sadly not uncommon with social cetacean species, where many animals appear to strand because they follow a sick, lost or panicked individual."

Nasa's Curiosity rover to begin Martian rock studies

Nasa's Curiosity Rover will study its first martial rock tomorrow, more than a month after landing on the Red Planet, mission officials said.
Mars Science Laboratory project scientist John Grotzinger said the rover drove for another 100 feet last night, for a total travel distance of 950 feet so far.
"So we are making steady progress toward Glenelg," a region where three different terrains join together, he told a teleconference. "We are actually half way there."
Curiosity is on a two-year mission to investigate whether it is possible to live on Mars and to learn whether conditions there might have been able to support life in

the past.
The science team plans to have Curiosity pause for a few days in order to perform the mission's first "contact science" by using instruments on the vehicle's robot arm

to photograph and analyse a pyramid-shaped rock.
The rock measures about 10 inches high by 16 inches wide at the base.
It will be photographed by the rover's Mars Hand Lens Imager, or MAHLI, and its Alpha Particle X-ray Spectrometer, or APXS, which can assess the rock's chemical

composition. Curiosity, equipped with a total of 10 scientific instruments, also has a powerful laser that can reach targets up to 23 feet away.
In recent days, the rover has snapped hundreds of photographs of three partial eclipses of the sun by the two Martian moons Phobos and Deimos.
Curiosity's final destination is the base of Mount Sharp, a mound of layered terrain at the heart of Gale Crater that could reveal clues about the geological history

of Mars. The journey is expected to take at least three months.

Swedish doctors claim 1st mom-daughter uterus transplant

Two Swedish women are carrying the wombs of their mothers after what doctors called the world's first mother-to-daughter uterus transplants.

Specialists at the University of Gothenburg completed the surgery on Sept. 15-16 without complications, but say they won't consider the procedures successful unless

the women achieve pregnancy after their observation period ends a year from now.
"We are not going to call it a complete success until this results in children," said Michael Olausson, one of the Swedish surgeons told The Associated Press. "That's

the best proof."

He said the women started in-vitro fertilization before the surgery. Their frozen embryos will be thawed and transferred if the women are in good health after the

observation period, Olausson said.

The university said one recipient had her uterus removed many years ago due to cervical cancer and the other was born without a uterus. Both women are in their 30s.

"Both patients that received new uteri are doing fine but are tired after surgery. The donating mothers are up and walking and will be discharged from the hospital

within a few days," team leader Mats Brannstrom said in a statement.

Turkish doctors last year said they performed the first successful uterus transplant, giving a womb from a deceased donor to a young woman. Olausson said that woman

was doing fine but wasn't sure whether she had started undergoing fertility treatment yet.

In 2000, doctors in Saudi Arabia transplanted a uterus from a live donor, but it had to be removed three months later because of a blood clot.

China lauded for ozone layer protection

BEIJING - The Ozone Secretariat of the United Nations Environment Program (UNEP) conferred a honor to the Chinese government for its contribution to ozone layer protection in an event marking this year's International Ozone Layer Protection Day that fell on Sunday.
Zhang Lijun, vice minister of environmental protection, said at the event that China has phased out more than 100,000 tons of ozone depleting substances (ODS) since 1991, an amount that accounted for around half the total disposed of by the developing countries.
Since signing the Montreal Protocol on Substances that Deplete the Ozone Layer in 1991, China continued to improve its management over ODS and phase out ODS production and consumption, contributing greatly to global efforts in ozone layer protection, according to Zhang.
China will face an "extremely arduous" task in meeting the next phase goal of ODS elimination set by the Protocol, he said.
Ozone shields the planet from the harmful ultraviolet-B radiation of the sun. It also completely screens out lethal UV-C radiation.
Signed by 24 nations in 1987, the Montreal Protocol set a global agenda for ODS elimination.

A difficult start: Astronomers reveal how planets can form in the centre of the Milky Way

At first glance, the center of the Milky Way seems like a very inhospitable place to try to form a planet.
Stars crowd each other, supernova explosions blast out shock waves, and powerful gravitational forces from a supermassive black hole twist and warp the fabric of space

itself.
However, US researchers now believe they have found proof that in this most difficult of environments, planets can form.
Astronomers at the Harvard-Smithsonian Center for Astrophysics found a cloud of hydrogen and helium plunging toward the galactic centre.
They argue that this cloud represents the shredded remains of a planet-forming disk orbiting an unseen star.
'This unfortunate star got tossed toward the central black hole.
'Now it's on the ride of its life, and while it will survive the encounter, its protoplanetary disk won't be so lucky,' said lead author Ruth Murray-Clay of the CfA.
The results are appearing in the journal Nature.
The cloud in question was discovered last year by a team of astronomers using the Very Large Telescope in Chile.
They speculated that it formed when gas streaming from two nearby stars collided, like windblown sand gathering into a dune.
Murray-Clay and co-author Avi Loeb propose a different explanation. Newborn stars retain a surrounding disk of gas and dust for millions of years.
If one such star dived toward our galaxy's central black hole, radiation and gravitational tides would rip apart its disk in a matter of years.
They also identify the likely source of the stray star - a ring of stars known to orbit the galactic center at a distance of about one-tenth of a light-year.
Astronomers have detected dozens of young, bright O-type stars in this ring, which suggests that hundreds of fainter Sun-like stars also exist there.
Interactions between the stars could fling one inward along with its accompanying disk.
Although this protoplanetary disk is being destroyed, the stars that remain in the ring can hold onto their disks.
Therefore, they may form planets despite their hostile surroundings.
As the star continues its plunge over the next year, more and more of the disk's outer material will be torn away, leaving only a dense core.
The stripped gas will swirl down into the maw of the black hole.
Friction will heat it to high enough temperatures that it will glow in X-rays.
'It's fascinating to think about planets forming so close to a black hole,' said Loeb.
'If our civilization inhabited such a planet, we could have tested Einstein's theory of gravity much better, and we could have harvested clean energy from throwing our

waste into the black hole.'

Clays in Pacific lavas challenge wet early Mars idea

A study of rocks at an old A-bomb test site in the Pacific has led a team of scientists to conclude that early Mars was not so warm and wet as many argue.

The rocks at Mururoa Atoll in French Polynesia contain clay minerals that look like those seen on the Red Planet.

But whereas the Martian clays are taken to be the products of weathering of rocks by liquid water, the atoll's clays have a very different origin.

These were precipitated directly from water-rich molten rock as it cooled.

The research is published in Nature Geoscience by Prof Alain Meunier from the University of Poitiers, France, and colleagues.

It is interesting because it strikes at the heart of the notion that the Red Planet was awash with water, perhaps at its surface, more than 3.75 billion years ago - an

idea that has been put forward to explain the great abundance of some clay deposits observed from orbit by satellites.

However, the process of clay production at Mururoa, if replicated and widespread on early Mars, would remove the need for such large volumes of water, and with it

possibly a more benign environment for life to establish itself on the planet.

"Mars was not as warm and wet in its earliest time as some have suggested. I do not believe in an early ocean on Mars," Prof Meunier told BBC News.

But [the Mururoa process] explains only the earliest generation of clays on Mars, in the early Noachian period. In later periods, liquid water has existed on Mars'

surface; that is undoubtedly the case."

Free space
The atoll was the site of French nuclear testing from the 1960s to the 1990s.

A lot of rock was drilled from the island as part of that programme and is now available for study.
Prof Meunier's team shows that clays in these volcanic samples were formed directly in place, in the spaces that sometimes arise between cooling rock crystals. They

were not the product of later alteration of the rock through long-term contact with water - the more familiar route to these minerals.

"Inside the basaltic rock as the lava is cooling, the crystals are separated sometimes by free spaces in which the residual fluids are concentrated," Prof Meunier

explained.

"These fluids contain all the components that have not been consumed in the high-temperature crystals like pyroxene, olivine and plagioclase; and among these

components, of course, there is water.

"As the temperature decreases, these fluids are supersaturated with a lot of phases that consume water and all the remaining elements. And this favours the formation

of clay minerals."

What is more, when the team examined the infrared reflectance of the Mururoan lavas, they found the signal to be very similar to the observational data obtained by the

Mars orbiters that have mapped the Red Planet's clay deposits.

Below the surface
Prof John Mustard, of Brown University, Rhodes Island, US, has studied the satellite clay data extensively since its first acquisition in 2005.

He said the new research was a welcome addition to the debate about the early environmental conditions on the planet but that he was not convinced the Mururoan lavas

could explain the great abundance of clays seen in some regions of the Red Planet.

"The question is: how do you generate thick sequences of this stuff? Their model cannot, I don't think, explain a Mawrth Vallis and other thick sections where we can

quite clearly demonstrate many hundreds of metres, if not more, of clay formation. Mawrth Vallis has far too much clay to be produced by this process. The amount of

clays produced by this degassing process is a relatively small amount."
Prof Mustard himself prefers the idea that many of the clays were produced sub-surface at Mars, where warm water could interact with rocks for long periods - such as

in hydrothermal systems. Only later were these buried clays excavated into view by impacts or through the erosion of overlying ground by short-lived bursts of flowing

surface water.

To maintain stable water on the surface of the planet for extended durations would have needed a thick atmosphere - something which is quite hard to reproduce in the

climate models of early Mars, explained Prof Mustard.

"We make the clear argument that a good chunk of the clays were subsurface," he told BBC News.

"I think it's abundantly clear that surface hydrologic systems were probably responsible for a subset of the clay occurrences that we see - but not the dominance.

There's very good evidence for there having been interconnected rivers and lakes, but they're very immature. This fluvial renaissance of Mars was very short-lived."

The debate is about to get lot more interesting thanks to the imminent first direct measurements of clay minerals on Mars.

Nasa has two operational rovers on the planet currently, and both should encounter the deposits.

The Opportunity vehicle is driving around the rim of a big crater known as Endeavour where clays have been sighted from orbit.

And the Curiosity robot, which has just landed in Gale Crater, will be commanded to drive to the base of a mountain where, again, clays have been detected by

satellite.

Mars rover Curiosity flexes its arm

A month after it landed on Mars, NASA's Curiosity rover extended its robotic arm this week and began a set of exercises that will test the arm's range of motion before it begins deploying the sampling and drilling tools attached to the complex instrument.

NASA scientists will spend six to 10 days while the rover is parked manipulating the 2.1-metre arm into various positions that it will need to be in when employing its various analytical instruments.

"These activities are important to get a better understanding for how the arm functions after the long cruise to Mars and in the different temperature and gravity of Mars, compared to earlier testing on Earth," Daniel Limonadi, lead systems engineer for Curiosity's surface sampling and science system, said in a media release.

Exercises delayed
The rover was to begin the arm exercises Thursday, but they were aborted after a temperature reading on the arm sent a caution signal; they started Friday instead.
The exercises are intended to test out how the arm will scoop up soil, drill into rocks and place samples into its analytical instruments.

"We're still learning how to use the rover," said Joy Crisp, deputy project scientist for the Mars Science Laboratory Project, which built and operates Curiosity from the Jet Propulsion Laboratory in Pasadena, Calif.

"It's such a complex machine — the learning curve is steep."

NASA gave reporters an update on the Curiosity mission on Thursday, saying that since landing inside Mars's Gale crater on Aug. 5 the rover has driven a total of 109 metres, more than the length of a football field.

The next stop in its two-year stay on the planet will be a rock formation called Glenelg, but it will take the rover several weeks to get there.

Curiosity takes a whiff of Martian air
NASA said the rover has taken its first gulps of Martian air using an instrument called the Sample Analysis at Mars, or SAM, which takes up more than half the payload of science instruments aboard the rover.
SAM is actually three separate instruments: a mass spectrometer, a gas chromatograph and a tunable laser spectrometer.

These sample and analyze the Martian atmosphere, measuring the abundance of elements such as carbon, hydrogen, oxygen and nitrogen, which will give scientists an indication of whether Mars may have at some point supported microbial life.

Scientists will be looking in particular for signs of methane, a short-lived gas that has been spotted by satellites orbiting Mars and by telescopes on Earth. If present, it will indicate there is some replenishing source of it on Mars.

The air samples Curiosity has begun taking are the first tests of Mars's atmospheric chemistry since the Viking Mars landers explored the planet in the 1970s.

NASA also released new colour pictures of the impact marks left by the rover's descent stage apparatus during landing and tracks the rover made on one of its first drives.

The images were taken by the Mars Reconnaissance Orbiter, which observes Mars from orbit.

Dawn probe leaves Asteroid Vesta

A signal from the probe confirming that it had escaped the gravitational bounds of the 530km-wide rock was received by Nasa on Wednesday.

The spacecraft's ion engine is now pushing it on to an even bigger target in the belt of asteroids between Mars and Jupiter - the dwarf planet Ceres.

Dawn is expected to reach this 950km-wide body in early 2015.

Before departing on its long cruise to the new destination, the probe trained its camera system on Vesta's northern pole.

The pictures reveal mountains and craters that are being seen for the very first time. Only now, as Dawn heads away, has the Sun risen high enough in the sky to illuminate the highest latitudes.

Scientists are poring over the images to see what interpretation they can put on the terrain.

Vesta has the appearance of a punctured football - the result of two mighty impacts that removed huge volumes of rock from its southern pole.

These collisions sent shockwaves rippling across the asteroid, producing a deep system of troughs that extends around the object's equator.

Researchers have speculated that this disturbance might also be reflected in the features hitherto obscured at the northern pole.

However, Dawn's principal investigator Prof Chris Russell said a definitive statement on such matters would have to wait on a detailed assessment of the new pictures.

"We haven't got together to discuss it carefully yet," he told BBC News. "[The region] is not as jumbled as I had expected; it's more subtle than I had expected - but the people who are experts in this particular area do feel that there is an effect of the southern impact."
The Dawn mission has returned a great swathe of data to transform our understanding of Vesta.

Before the probe's arrival in July last year, the best views of the asteroid were some fuzzy pictures acquired by the Hubble Space Telescope.

Dawn studied in detail the pattern of minerals exposed at Vesta's surface and also mapped the diverse geological features shaping its terrain.

These observations have enabled scientists to elucidate a history for the colossal rock.

They now regard it as a unique body - the only remaining example of the original objects that came together to form the rocky planets, like Earth and Mars, some 4.6 billion years ago.

It is clear now that Vesta has a layered interior, with a metal-rich core that takes up some 18% of the body by mass.

All of the other objects like it at the Solar System's birth were either obliterated in the intense collisional environment that existed back then or were incorporated into successively larger aggregations of material that eventually produced the planets we recognise today.

Perhaps the stand-out discovery is the definitive association that can now be made between Vesta and the howardite-eucrite-diogenite, or HED, class of meteorites that regularly fall to Earth.

From telescopic observations, researchers had always suspected these meteorites came from Vesta. But the signatures of pyroxene - a mineral rich in iron and magnesium - in those meteorites have now been matched precisely with the mineral signatures spied in Vesta's surface by Dawn's instruments.

It is highly likely that much of the HED material was thrown off Vesta in those two big impacts at the southern pole.

"We have used those meteorites and their chemical analysis to tell a story about the formation of the Solar System and its evolution, and if that was wrong we'd have had a lot of explaining and new work to do. The fact that it is right, and we've confirmed it, is really very good. It makes our lives a lot simpler," said Prof Russell, who is affiliated to the University of California, Los Angeles.

Why biodiversity increases

Periods of the earth's warming are associated with an increase in biodiversity, according to a study published this week in the Proceedings of the National Academy of Sciences. While this may sound like good news, the timescales involved cancel out any benefits they might experience from the rising temperatures.

The team behind the study, led by Dr Peter Mayhew at York University, examined the earth's geological history and fossil records using improved data sets that looked at patterns of marine invertebrate biodiversity over the last 540m years.

They found that biodiversity increases over periods of warming in the earth's climate with many new species emerging, although these are simultaneously accompanied by extinctions of existing species.

Mayhew said: "What seems to be happening is that when we get a warming, this coincides with an upward shift in biodiversity in groups of organisms. So it looks like warm periods are boosting the generation of new species and that's improving biodiversity. However a bit later, and when I say 'a bit', I mean several millions of years later, you get extinctions occurring."

"It's a kind of a mixed picture," he added." We get an improvement in diversity but we also get extinction in new groups. It's just that overall the origination tends to out-do the extinction so biodiversity improves, generally."

But Mayhew doesn't think this changes what we currently understand concerning the loss of species as a result of today's man-made global warming.

"I don't think that there is any good news here", says Mayhew. "If what we need for diversity to improve in these warm climates is time for those organisms to evolve, then that time is going to be much longer than the lifetime of the human race. The lifetime of a species tends to be 1-10m years in the record. So that's how long we can expect humans maybe to survive ... if we get a fair chance at life.

"But I'm afraid it's not good news in terms of what we might experience from global warming in the next few decades. Because obviously extinction can happen rapidly, but speciation [the generation of new species] can't happen rapidly. So unfortunately we're quite likely, simply because of the rate of climate change today, to see extinctions occurring. And we're unlikely to see the benefits that might go along with that, which is the generation of new species."

Therefore despite of the possibility that climate change sceptics might takes these latest findings to suggest that the current warming of the planet is a good thing, Mayhew is very clear about what should be taken away from this study.

"Probably warming is good for speciation. In fact there are a lot of ecological studies that have suggested that there is the potential for earth to support biodiversity may in fact be greater under a global warming scenario. The difficulty is that potential doesn't necessarily translate into reality and species have to exist in order to fulfil that potential.

"I follow the scientific consensus here. The scientific consensus is definitely that current global warming is going to lead to a loss of biodiversity and potentially quite a significant loss. I don't think there is any good data to say otherwise at the moment and most of the data we have is strongly in that direction." He pointed out, for example, that there are big concerns about what is happening in the coral reefs.

So while the study does give us an insight into what happened to species when the planet warmed millions of years ago, it doesn't contradict predictions of greater species extinctions due to current rates of climate change.

No life on Mars: an eerie foretaste of Earth's future?

Between Knobel and Wien, south of the Aeolian Plain, to the west of the ditches of Cerberus, the mighty strata of Mount Sharp rise out of Gale Crater. None of these names have ever been spoken on Mars, where this photograph was taken by Nasa's Curiosity rover before it started its slow journey across the landscape this week. They are names given by humans, some in the official language of scientific nomenclature, Latin, others – like Mount Sharp – more pet names for vast and remote geographical features.

If the first vague images from Curiosity seemed pale beside science fiction fantasies of life on Mars, this high resolution (and colour-adjusted) picture of Mount Sharp is sublime and awe-inspiring. The 18th century writer Edmund Burke said the glorious horror of the sublime is evoked in us by phenomena that might threaten our existence. The immense cliffs, screes and gullies of this mountain vista, set in an atmosphere too weak to sustain humans, reveal a landscape of lifeless grandeur that surely inspires such mixed emotions. It is a marvellous place that eerily mirrors the most spectacular sights on earth, from the Grand Canyon to the Sahara.

It is easy to see from this picture why Nasa has chosen Mount Sharp as a destination for its most sophisticated robot explorer yet. Curiosity's job is to search for evidence that Mars could have once supported life. The exposed strata that can be seen here must contain, like rock strata on earth, a rich geological history of Mars. Evidence of ancient life-supporting conditions may be found here if anywhere.

Yet "rich" may not be the word. How much chance is there of even the tiniest fossil life form being encountered by Curosity? On Earth, the remote ancient rocks of places like the Burgess Shales in Canada contain weird forms such as the early Cambrian creepy-crawly Hallucigenia. Go for a walk nearly anywhere and you can find fossils of some kind. You don't have to look long, in other words, to find evidence of ancient life in Earth's rocks. Meanwhile in this desolate Martian landscape a machine sent by Earth's most ambitious life forms will pick over the pebbles in search of the merest trace of the possibility of life.

This picture is thrilling and it is terrifying. It is a mirror of Earth's rocky architecture if somehow our planet became lifeless.

Meanwhile on Earth, Republican presidential hopeful Mitt Romney was making the speech of his life as he launches his bid to run the world's most powerful democracy. "President Obama promised to begin to slow the rise of the oceans and heal the planet", he said. "My promise ... is to help you and your family."

And that's when the scientific magnificence of this photograph turns to dread. While we gaze in wonder at a dead planet, what is happening to the living one? The start of Curiosity's mission has coincided with a summer full of danger warnings for life on earth. Suddenly, debates and pseudo-debates about climate change are ancient history. The record melting of Arctic ice this summer points clearly to ice-free summers in the Arctic in the near future. Nasa itself, not long before its Mars mission touched down, discovered startling satellite evidence of an equally dramatic melting of the ice sheet on Greenland. Even former sceptics are accepting the reality and urgency of a change in the life of the Earth caused mainly by human activity.

Mars is a beautiful place, as this picture shows, but it is majestically dead. The universe appears to be full of places like that. What no one has so far found much trace of is a place like this: a planet that jumps with life. Earth is a miracle, quite possibly the greatest miracle in the entire cosmos. It is now proven beyond any reasonable doubt that we are playing dangerously with the very fabric of that miracle, endangering the biological balances of our amazing world. Endangering ourselves. In this picture we look on a dead world. Do those silent strata reveal the Martian past, or our future?

EXCLUSIVE-Amazon teams with Nokia, snubs Google for maps -sources

SAN FRANCISCO, Aug 30 (Reuters) - Amazon.com Inc's (AMZN.O) new Kindle Fire will have mapping services via a tie-up with Nokia Oyj (NOK1V.HE), according to two people familiar with the situation, filling a gap in the tablet's capabilities while snubbing Google Inc's popular service.

The world's largest Internet retailer, which says its nine-month old Kindle Fire now accounts for one in five U.S. tablet sales, has teamed up with Nokia on mapping, the two people told Reuters.

Amazon will release at least one new version of the Kindle Fire next Thursday.

Amazon will also add location capabilities to the new Kindle Fire, which requires either a GPS chip or a process known as WiFi triangulation, the people said on condition of anonymity because they were not authorized to speak ahead of Thursday's launch event.

Mapping services, which are popular features on tablets, typically include street maps, information about local businesses and sometimes traffic status. They can also support navigation instructions and third-party applications that depend on location information, such as travel services.

Location capabilities mark the location of tablet and smart phone users.

Google Inc's (GOOG.O) Nexus 7 tablet, which competes directly with the Kindle Fire, comes with GPS receiver chips to support location and mapping functions.

The first Kindle Fire launched last year and at $199 costs half the price of the entry-level Apple Inc (AAPL.O) iPad, helping it rapidly gain consumer acceptance. On Thursday, Amazon said its Kindle Fires had completely sold out. [ID:nL2E8JU6CF]

Analysts say the 7-inch device helps drive sales of digital media such as ebooks and music, which in turn propels core retail growth for the company.

Amazon may unveil larger versions of the Fire on Thursday in Los Angeles, analysts and media say, which will compete more directly with the iPad.

Although the Kindle now runs on an early version of Google's Android, which Amazon developed into its own operating system, it does not integrate Google Maps into the device. That means users had to access Google Maps via a Web browser, or download map apps from third-party developers.

A Nokia spokesman declined to comment and an Amazon spokeswoman did not respond to requests for comment.

GOING NATIVE

Shares of the Internet retailer closed down 0.4 percent at $246.22 on Thursday, after hitting a record high of $250 earlier following the announcement that it had run out of Kindle Fires.

Cooperating with Nokia may help Amazon develop integrated, or "native," mapping functionality for the Kindle Fire without relying on Google Maps. Nokia is one of the world's largest mapping companies, through its 2007 acquisition of Navteq.

Apple took a similar step earlier this year, when it dropped Google Maps in favor of its own mapping features for its next mobile operating system, known as iOS 6. As part of the switch, Apple signed a global licensing deal with TomTom NV (TOM2.AS), another leading mapping company, for its map content and related information.

In July, Amazon agreed to buy mapping startup UpNext, which specializes in detailed 3D maps of cities and some sporting stadiums.

Arctic Sea Ice Reaches Record Low With Weeks Left in Melting Season

Arctic sea ice is melting faster than climate models projected, already shrinking to a record minimum with several more weeks of this year’s melting season, according to scientists on both sides of the Atlantic.
“The sea ice area went below the sea ice area in 2007 around Aug. 20,” said Ola Johannessen , founding director of the Nansen Environmental and Remote Sensing Center, an independent non-profit research foundation affiliated with the University of Bergen, Norway, that conducts basic and applied environmental and climate research.
“In general, the ice area and extent has consistently decreased since 1960 and the reason is mainly the increase of CO2,” he said.
According to a report released today by U.S. National Snow and Ice Data Center, Arctic sea ice area has shrunk to 1.58 million square miles, breaking the previous minimum of 1.61 million square miles, set in 2007.
What Will This Mean for the World?
With more water ice-free, the amount of shipping through the Northern Sea Route and the North West Passage, even directly across the Arctic Ocean, will increase, Johannessen said.
There could also be increased oil production, since the the Arctic holds 32 percent of the world’s untapped oil  and gas reserves. Russia has put its first oil rig in the Arctic into operation, but it became a target of environmentalists last week when Greenpeace activists scaled it in protest.
But according to the National Snow and Ice Data Center, the loss of sea is likely to accelerate global warming trends.
“We’re seeing a decline of roughly round 12 percent per decade, 60,000 square miles per year.  To give a sense of that, the average U.S. state size is about 30,000 square miles.  Which means we’re losing about losing an average state every two years in terms of average sea ice cover,” NSIDC research scientist Walt Meir told ABC News.
Arctic sea ice keeps the polar region cold and helps to moderate global climate. Over the past 30 years there has been a dramatic decrease in the thickness and extent of ice in the arctic.
“Melting of the Arctic is bad for climate change and fisheries,” Johannessen said.  Loss of sea ice will impact “ocean and weather patterns, and there will be increased teleconnection between high and low latitudes affecting the monsoon system in Asia and other parts of the world.”
Melt Also Self-Reinforcing
There’s no turning back, scientists agree.  Since sea ice is white, it reflects 80 percent of the sunlight hitting it back back into space; the less of it is the more heat the darker Arctic will absorb. Instead of reflecting 80 percent, it will absorb 90 percent of the sunlight,  which will accelerate the thaw, scientists say. Several studies have found the Arctic could be ice free by 2040 or sooner.
As the Arctic melts, the ocean around it becomes warmer, leading to more loss of sea ice, and therefore a rise in sea levels.  Scientists say this sea level rise is impossible to avoid.
The Arctic Ocean has been covered with ice for more than 2.5 million years. During interglacial periods like the current one, ice melts in the summer and thaws in the winter.  Arctic sea ice reaches its maximum seasonal extent in March and shrinks through spring and summer to a minimum extent in September.
“The Arctic sea ice cap was acting kind of like an air conditioner for the earth’s climate system, and keeping it cooler than it would have been without the ice, and now we’re starting to lose that, we’re starting to lose coolant from that air conditioner in a sense,” Meir said.  ”We’ve lost 40 percent of Arctic sea ice in the summertime, that’s effectively like taking everything east of the Mississippi, and a little bit west away.”
Throughout human civilization, this melting and freezing Arctic sea ice has been more or less consistent. However,what is being experienced now is unprecedented, scientists say.
“These climate systems are interconnected. These climate systems are not like Las Vegas: What happened in the Arctic does not stay in the Arctic,” Meir told ABC News.  ”As the Arctic warms, as the balance changes, it may affect things like average rainfall, we’ll have more droughts in some areas, some areas will have more rain. Heavier snowfalls in winter, there was a big ‘snowpocalypse’  in Washington, D.C., a couple of years ago, and there was some indication sea ice might have played a role in that.  It’s hard to pinpoint isolated events, but thing like that are things we will expect to see as the ice decreases.”
