Ocean discovered on Enceladus may be best place to look for alien life

Guardian Science - Thu, 2014-04-03 19:25
Evidence from Cassini spacecraft suggests a large body of liquid water beneath the surface of Saturn's moon Enceladus

Interactive: the discovery explained

Researchers have discovered a deep saltwater ocean on one of the many small moons that orbit Saturn, leading scientists to conclude it is the most likely place in the solar system for extraterrestrial life to be found.

Gravitational field measurements taken by Nasa's Cassini space probe revealed that a 10km-deep ocean of water, larger than Lake Superior, lurks beneath the icy surface of Enceladus at the moon's south pole.

When I met Jane Goodall, she hugged me like a chimp

Guardian Science - Thu, 2014-04-03 12:02

Jane Goodall, inspiration to millions, is 80 today. In December, she gave me two hours of her time, during which I asked her about her childhood, her work with the Gombe chimps and her life as an activist.

In February 1935, the year of King George Vs silver jubilee, a chimpanzee at London Zoo called Boo-Boo gave birth to a baby daughter. A couple of months later, a little blonde-haired girl was given a soft-toy replica of the zoos new arrival to mark her first birthday. This was Jane Goodalls first recorded encounter with a chimp.

Goodall is 80 today (happy birthday Dr Jane). In the intervening years, her research on a community of chimpanzees in Tanzania revolutionised our understanding of these primates, our closest living relatives, and challenged deepset ideas of what it means to be human. She then packed in her fieldwork to become an activist, campaigning tirelessly for a more enlightened attitude towards animals and the environment. Along the way she has received nearly 50 honorary degrees, and became a UN Messenger of Peace in 2002 and Dame Jane in 2004.

Science has nothing to tell us about the soul? I disagree | Andrew Brown

Guardian Science - Thu, 2014-04-03 10:06
To completely separate science from philosophy is to neglect the fact that they are reliant on each other, like two sides of an arch

Can science tell us anything about the soul? A lovely clear answer came from Iain McGilchrist, talking at the RSA this week. "No," he said, and the room filled with laughter, not entirely kindly. He had been responding to a questioner who wanted to know whether the increasing sophistication of brain imaging would not reveal the soul to be an illusion, an unnecessary imprecision.

"To expect that we will find something in the brain that corresponds with the soul is just crass," he said. The moderator, Jonathan Rowson, pressed him: "Is it the case that science can help us understand better what the soul is?"

Ketamine may help treat depression, UK study finds
