It's been suggested that asteroids delivered water to a bone-dry early Earth, but whether that would work in practice remained unanswered. Now scientists at Brown University have tested the theory using a high-powered cannon, and found that a surprising amount of water is transferred in the process.

Over the last few years, perovskite has proven itself to be a promising material for photovoltaic solar cells, but it’s not without its problems. Now, a team has found a way to helps solve at least one of those issues, removing toxic lead from the device by substituting in titanium.

Rather than focusing on a longer lifespan, it’s a better to improve our “healthspan,” the time we can enjoy good health. A new study from Brown University has linked the protein Sirt4 with an extended healthy lifespan in fruit flies, and the find may carry across to humans.

Eighty-five percent of all matter is dark matter, a theoretical substance that doesn’t interact with ordinary matter and has so far eluded our best efforts to directly detect it. Now physicists have proposed a new way to find dark matter using a huge tub of helium in a superfluid state.

With blistering daytime temperatures of up to 800º F (427º C), Mercury isn’t the first planet in the solar system you’d think to look for ice, but conditions at the poles are perfect. Now, a new study from Brown University has found that Mercury may be even icier than previously thought.

The Moon seems like a pretty barren place, but studies in 2009 revealed traces of water in the lunar soil. Now, scientists have used NASA's Moon Mineralogy Mapper to construct a detailed map of where water can be found on the Moon – and it turns out it’s more widespread than previously thought.

Scientists had thought our Moon to be mostly free of water up until around a decade ago. But a new study has drawn on satellite data to uncover volcanic deposits spread out across its surface that contain surprising amounts of trapped water, raising questions around how the Moon was formed.

Although ceramics are known for being able to withstand high temperatures, they also have a reputation for being brittle. That's not the case, however, with a spongey new material made from ceramic nanofibers. It could find use in high-temperature insulation or water filtration.

It's a cutthroat world out there, and the male cuttlefish is not above using sneaky tactics to fool rivals. But what causes a mild-mannered trickster to morph into a fighter? The answer can be found in the footage below, the first of its kind to capture a male cuttlefish brawl in the wild.

“Mini-brains,” models created from 3D cultures of neural cells, could help reduce our reliance on animal testing. Now researchers have discovered the neural cells are growing their own blood vessels too, opening the door for better studies of stroke, Alzheimer’s and concussion.
