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.’
