How Earth became a giant snowball 700 million years ago

Harvard scientists say they might finally have the answer to what caused the

Around 717 million years ago, the Earth froze over. The Sturtian glaciation, as this event is known, was no ordinary Ice Age but one so extreme that it caused the Earth to become a giant snowball for at least five million years. How it happened has been a mystery for the ages – till now. In a new study, Harvard scientists suggest that the answer might lie in the way volcanic eruptions caused the Earth's temperatures to plummet.

Some big claims for a little drone

The Kudrone is equipped with a 4K camera, GPS and a position-holding system

Mini drones may be kind of fascinating to some of us, but the things are notoriously difficult to keep hovering in one place, plus they're not known for shooting great video. Chinese startup Ruiven claims to be out to change that, however, with its new Kudrone. The tiny quadcopter shoots at a maximum resolution of 4K, it can pivot 360 degrees to shoot panoramic stills, plus it's equipped with GPS.

Superclean: Light and quantum dots turn plants into hydrogen

Scientists have been sprouting new ways to cleanly produce hydrogen as a fuel source

Hydrogen is often touted as a clean fuel source, as its use in cars only produces water vapor as a byproduct. The truth is though, that producing hydrogen in the first place can often be a process that relies on natural gas or other polluting chemicals that can damage the environment. Finding a way to produce hydrogen simply and cleanly would go a long way toward eventual use of the gas as a fuel source. And that's exactly what researchers at the University of Cambridge have done, adding to a host of other green possibilities that have been proposed for creating the gas.

Study: Spiders eat more annually than weight of all human adults

A wolf spider preparing to eat some insects (probably)

Some larger types might opt for a lizard or even a frog, but the great majority of spiders love to eat insects. We mean really, really love to eat insects. So much so, that the world's spiders consume somewhere between 400 and 800 million tons of biomass each year consisting almost entirely of creep crawlies, a new study has shown. That's around twice the combined weight of all the world's adults, in case any arachnophobes were wondering.
