Climate change on the Red Plant: Mars is emerging out of an ice age

Swirling patterns in the ice of Mars’ North Pole suggest the planet is emerging out of a long ice age that began some 370,000 years ago. The findings are extremely important for climate change, improving our understanding of both Mars’ and Earth’s climate.

Archimedes’ legacy: inventions and discoveries

How to catch a sunbeam (or slowing down the speed of light to a halt)

In vacuum, light always travels at a constant speed of 299,792,458 metres per second. Nothing can travel faster than this constant c, as denoted by physicists. These two postulates are basic building blocks of modern physics and were first announced more than a hundred years ago by Albert Einstein. Yet, there are ingenious ways to slow light to the point of trapping it in a dead stop. Prepare for some weirdness.

Decade-long study shows how air pollution is killing you
