A study has shown that elephants instinctively understand when humans point, making them unique in the animal kingdom.
Astronomers have found evidence that an Earth-like planet may have hosted life hundreds of millions of years ago.
Ahead of the release of a film about his life, Stephen Hawking has insisted he wants to be remembered as a scientist and not a celebrity.
Men and women's brains really are wired differently, according to a new scientific study.
Men generally have more connections within each hemisphere of the brain, while in women the two halves of the brain are much more interlinked, scientists say.
The male brain also contain more nerve fibres while the female brain has a greater proportion of "grey matter," consisting of the cell bodies of neurons.
A Christmas tree has been lit up by a very green battery - made entirely of brussel sprouts.
Paul Jackson told Daybreak power was generated using electrodes in the brussel sprouts, though admitted the electricity did not last long.
He explained: "What happens here is that we have electrodes in all of these sprouts and they turn into little batteries and it's like the first battery a couple of hundred years ago but realised with brussel sprouts."
Mr Jackson hopes the brussel sprouts battery would spark children's enthusiasm for science and engineering and encourage them to visit the Big Bang Fair next year.
British biochemist and two-time Nobel Prize winner Frederick Sanger, has died at the age of 95, the Associated Press reports.
Sanger is considered by many to be the "father of genomics" as he and his colleagues developed methods of DNA sequencing in the 1970s.
He was awarded the Nobel Prize in Chemistry in 1958 and 1980.
Advertising at the cinema is less effective when viewers eat popcorn, a new study found.
Researchers at Cologne University found that audiences remember brands because their lips and tongues automatically simulate the pronunciation of a new name.
However, this "inner speech" can be disturbed by chewing, rendering the effect redundant, the study published in the Journal of Consumer Psychology showed.
Nobel Prize-winning scientist Professor Peter Higgs has revealed that he first learned of his award when a former neighbour stopped him on the street to tell him.
"She congratulated me on the news and I said 'oh, what news?" he said.
"She told me her daughter phoned from London to alert her to the fact I had got this prize. I heard more about it obviously when I got home and started reading the messages."
Higgs was awarded jointly for his work on the Higgs boson, the so-called "God particle" which gives matter its mass. Its existence was proved in 2012, 50 years after his work.
"Obviously I'm delighted and rather relieved in a sense that it's all over," Higgs said. "It's been a long time coming."
The evidence "seems to be building that we are actually all Martians" and "that life started on Mars and came to Earth on a rock," according to a scientist from The Westheimer Institute for Science and Technology in the US.
Professor Steven Benner said, "It's lucky that we ended up here nevertheless, as certainly Earth has been the better of the two planets for sustaining life. If our hypothetical Martian ancestors had remained on Mars, there might not have been a story to tell."
Prof Benner told the Goldschmidt 2013 conference in Italy that the oxidised mineral form of the element molybdenum, "couldn't have been available on Earth at the time life first began, because three billion years ago the surface of the Earth had very little oxygen, but Mars did".
"It's yet another piece of evidence which makes it more likely life came to Earth on a Martian meteorite, rather than starting on this planet," he added.
