Scientists have discovered the earliest evidence of human footprints outside of Africa, on the Norfolk Coast in the East of England.
The footprints are more than 800,000 years old and were found on the shores of Happisburgh.
They are direct evidence of the earliest known humans in northern Europe.
Details of the extraordinary markings have been published in the science journal Plos One.
The footprints have been described as "one ...
Children who live near overhead power lines do not have an increased risk of developing leukaemia, a study has said.
Data on 16,500 children who developed leukaemia in Britain between 1962 and 2008 was analysed.
The paper found no increased leukaemia risk for those living near power lines from the 1980s onwards - but a higher risk did exist in the 1960s and 70s.
The researchers said the findings were "reassuring" but work was ...
There is more evidence that salmon use the Earth's magnetic field to perform extraordinary feats of navigation.
A study suggests that Pacific salmon are born with an in-built "magnetic map" that helps them to migrate over thousands of kilometres.
US researchers believe the fish are sensing changes in the intensity and angle of the Earth's magnetic field to establish their position in the ocean.
The study is published in the journal Current Biology.
The epic ...

Europe's billion-star surveyor, Gaia, is on track to begin operations in the next two or three months.
Launched in December, the satellite has now taken up its observing station some 1.5 million km from Earth.
Engineers are currently commissioning Gaia's two telescopes and its three instruments, getting them ready to begin mapping the precise positions and motions of one-thousand-million stars.
As part of that process, an ...

A Nasa spacecraft in orbit around the Red Planet has spied a fresh impact crater on the Martian surface.
The hole is about 30m (100ft) in diameter and surrounded by a blast zone of debris punched out of the ground by the meteorite impact.
The explosion that generated this crater tossed out debris as far as 15km (9.3 mi).
The image was taken by the ...
The globe is facing a "tidal wave" of cancer, and restrictions on alcohol and sugar need to be considered, say World Health Organization scientists.
It predicts the number of cancer cases will reach 24 million a year by 2035, but half could be prevented.
The WHO said there was now a "real need" to focus on cancer prevention by tackling smoking, obesity and drinking.
The World Cancer Research Fund said there was an "alarming" level ...
In June last year, police at San Diego International Airport noticed a passenger's bag was smoking as it journeyed around the carousel.
Inside, a lithium-ion battery had touched a screwdriver and both had melted.
In September 2012, a flight attendant and two passengers were burned when they handled a mobile phone and spare battery that overheated during a flight.
In April 2012 a lithium battery inside someone's personal air purifier caught fire at 28,000ft.

The Curiosity Mars rover is to try to drive over a one metre-high dune.
The sand bank is currently blocking the robot's path into a small valley and a route with fewer of the sharp rocks that lately have been making big dents in the vehicle's aluminium wheels.
US space agency engineers will take no risks, however. The rover will be commanded initially to climb only part way up ...
