A highly sensitive magnetic material that could transform computer hard drives and energy storage devices has been discovered.
The metal bilayer needs only a small shift in temperature to dramatically alter its magnetism - a tremendously useful property in electronic engineering.
"No other material known to man can do this. It's a huge effect. And we can engineer it," said Ivan Schuller, of the University of California, San Diego.
He presented his findings at the ...
The first patient to be fitted with a pioneering artificial heart in France has died.
The 76-year-old man, who has not been named, died 75 days after the operation in Paris.
The bioprosthetic device, made by French company Carmat, is designed to replace the real heart for up to five years.
It is intended to help patients who are in the advanced stages of heart failure.
At this late stage of the disease, the ...
An independent scientific assessment of last year's pilot badger culls in parts of Gloucestershire and Somerset has concluded that they were not effective.
Analysis commissioned by the government found the number of badgers killed fell well short of the target deemed necessary, the BBC understands.
And up to 18% of culled badgers took longer than five minutes to die, failing the test for humaneness.
The pilot culls were intended to limit the spread of TB ...

A rare example of prehistoric rock art has been uncovered in the Highlands.
Archaeologists made the discovery while moving a boulder decorated with ancient cup and ring marks to a new location in Ross-shire.
When they turned the stone over they found the same impressions on the other side of the rock. It is one of only a few decorated stones of its kind.

Apprentices are being invited to take one giant leap for mankind and sign up for elite space engineering training.
The first degree-level apprenticeship in the field is being launched by Skills Minister Matthew Hancock at the National Space Centre in Leicester.
The programme aims to encourage more scientists and engineers into the UK's space industry, expected to be worth £30bn in the next two decades.
The Royal Astronomical Society says this demand is not currently ...

A tiny 4.4-billion-year-old crystal has been confirmed as the oldest fragment of Earth's crust.
The zircon was found in sandstone in the Jack Hills region of Western Australia.
Scientists dated the crystal by studying its uranium and lead atoms. The former decays into the latter very slowly over time and can be used like a clock.
The finding has been reported in the journal Nature Geoscience.
Its implication is that ...

Scientists say they have observed a record-breaking impact on the Moon.
Spanish astronomers spotted a meteorite with a mass of about half a tonne crashing into the lunar surface last September.
They say the collision would have generated a flash of light so bright that it would have been visible from Earth.
The event is reported in the Monthly Notices of the Royal Astronomical Society.
"This is the largest, ...
