Model predicts more snow at the poles

Most of us will see less snow over the coming years - but polar and high-altitude regions will get more, a new climate model from the National Oceanic and Atmospheric Administration (NOAA) predicts.

Habitable zone redefined - and we're barely in it ourselves

We can all be picky at times, but you probably think of this planet as reasonably bearable. In a new model for what constitutes a habitable zone, however, the Earth barely scrapes over the bar.

Model may explain origin of life

It's always been a bit of a mystery as to how life began on a molecular level. Theories tend to involve a network of molecules that have the ability to work together to jumpstart and speed up their own replication.

New evidence supports impact theory of moon's creation

It's long been theorized that the moon was created when a Mars-sized proto-planet slammed into the Earth. Unfortunately, though, the chemistry of the two bodies has stubbornly failed to bear this out.

Thousand years of sea rise 'inevitable'

Whatever we do, greenhouse gas emissions have alreadytriggered an irreversible warming of Earth that will cause sea levels to rise for more than a thousand years to come, claims a European team.

Plastic debris found littering ocean

There's far more little bits of plastic in the ocean than previous studies have indicated, according to new research.

Greenland ice sheet may melt completely

The Greenland ice sheet appears more vulnerable to global warming than previously thought, and could disappear altogether if global temperatures rise more than 1.6 degrees Celcius above pre-industrial levels.

LHC ATLAS experiment recreated in LEGO

Irritated, perhaps, by CERN's tardiness in producing a Higgs boson for our delectation, a Danish scientist has produced a detailed model of the Large Hadron Collider's ATLAS experiment - made from LEGO.

Model shows effects of giant meteorite strike

Ever wondered exactly what would happen if a massive meteorite hit the Earth? Princeton University scientists can show you.

Galaxy simulation mirrors Milky Way for first time

Astrophysicists have for the first time created a computer model of galaxy formation that results in a spiral galaxy like our own.

Melting permafrost could ramp up global warming

Thawing permafrost could release billions of tons of carbon into the atmosphere by the end of this century, further accelerating global warming.

Million-processor computer to model the human brain

Up to a million ARM processors are to be linked together to create a massive computer, called SpiNNaker (Spiking Neural Network architecture) that can simulate the workings of the brain.

Which technologies improve the fastest?

Some technologies have remained the same for centuries; others seem to change every five minutes. But how are researchers to know where it's worth investing time and money in looking for improvements?

Report: Apple cracks down on sexy apps

Saint Steven Jobs and his puritanical Apple minions may be in the process of purging "overtly sexual" content from the hallowed App Store.
