How to backup life on Earth ahead of any doomsday event

NASA says there are ten “potentially hazardous” asteroids close to Earth. Good reason to make sure we have a backup plan should any catastrophic event wipe of much of life on Earth.

Dear diary: another day in the life on Mars

One of the best ways to find out the challenges of living on Mars is to simulate living on another planet here on Earth. So what’s it like to spend several months living the Martian life?

No more playing games: AlphaGo AI to tackle some real world challenges

The artificial intelligence that beat a world master at the game of Go is now to be directed at more complex global problems. So what can we expect?

Hidden feather patterns tell the story of birds

Ordinary grey bird feathers placed under X-ray fluorescence reveal beautiful patterns of elements like zinc, telling a story of feather growth and the environments the birds have experienced.

A new discovery of gravitational waves has black holes in a spin

Scientists have made a third detection of gravitational waves, again caused by the merger of two black holes. But they think there’s something different about the black holes in this case.

Juno mission unveils Jupiter’s complex interior, weather and magnetism

We may need to re-think our models of Jupiter’s formation thanks to the first results from Juno probe orbiting the planet, and new observations from Earth.

Not dead yet: how MP3 changed the way we listen to music

The MP3 audio file transformed the way we accessed music online. So what does it mean now that licensing and support for the popular format is to end?
Imagine a world where artificial intelligence is in control and humans are brink of extinction. What went wrong? What could we have done? Shutterstock
