A major study suggests that killing among chimpanzees results from normal competition, not human interference.
Apart from humans, chimpanzees are the only primates known to gang up on their neighbours with lethal results - but primatologists have long disagreed about the underlying reasons.
One proposal was that human activity, including destroying habitats and providing food, increased aggression.
But the new findings, published in Nature, suggest this is not the case. ...

Scientists and engineers have spent weeks studying the 4km-wide "ice mountain" known as 67P, looking for a location they can place a small robot.
They have chosen what they hope is a relatively smooth region on the smaller of the comet's two lobes.
But the team is under no illusions as to how difficult the task will be.
Comet 67P/Churyumov-Gerasimenko, currently sweeping through space ...

Imagine opening the curtains in the morning and instead of grey skies and rain, looking out at a rust-coloured rocky panorama.
The year is 2045. You have woken up on Mars.
If you build it
Colonising Mars could happen sooner than you think. Elon Musk plans to build a city there. Nasa wants to send people by 2035. Then there's the Mars One mission, Big Brother for the slightly suicidal. ...

Construction has begun on a giant observation tower in the heart of the Amazon basin to monitor climate change.
The Amazon Tall Tower Observatory is expected to rise 325m from the ground.
Its instruments will gather data on greenhouse gases, aerosol particles and the weather in one of the largest continuous rain forests on the planet.
Brazilian and German scientists hope to use the data to better understand sources of greenhouse ...
LIGO 1st Gen
The Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) instrument, a laser "ruler" built to measure the traces of gravitational waves, is progressing at amazing speed, scientists say.
The first generation of LIGO, which ran between 2001 and 2010, saw nothing.
Over the last four years scientists have designed a more sensitive detector that achieved "full lock" in June this year, earlier than planned.
Researchers reported that the new one is already 30% ...
A robot unveiled today at the British Science Festival will be loading dishwashers next year, its developers claim.
"Boris" is one of the first robots in the world capable of intelligently manipulating unfamiliar objects with a humanlike grasp.
It was developed by scientists at the University of Birmingham.
The team also work with "Bob", an autonomous robot who recently completed work experience at security firm G4S.
"This is Boris' first public outing," announced Professor ...
The brain is still active while we are asleep, say scientists, who found people were able to classify words during their slumber.
Researchers from Cambridge and Paris introduced participants to a word test while awake and found they continued to respond correctly while asleep.
The sleeping brain can perform complex tasks, particularly if the task is automated, the study says.
Further research will now focus on how to take advantage of our sleeping time.
