A study has found that hailstones form around certain biological materials. This presents a new way of thinking about the formation of snow and rain.

Nanoparticles used to monitor for cancer

Researchers have developed new nanoparticles that can be used for magnetic resonance imaging (MRI). This application could help medics to monitor a tumor’s environment and to assess if drugs have successfully reached their targets.

Graphene helps to construct flexible solar cells

Researchers have devised a new type of cathode that could be readily used to manufacture inexpensive, flexible dye-sensitized solar cells.

Cartilage cells can 'sense' injury

Researchers are examining how human cartilage senses mechanical strain at the cellular level. It seems that a pair of channels that work together to cause cartilage cells to die off in droves. New research suggests that this mechanism can be blocked.

Scientists one step closer to resurrecting the woolly mammoth

Scientists may finally have what they need in order to resurrect a woolly mammoth, but there's one really big if: They need to find the mammoth's complete DNA, and with a mammoth named Buttercup, they may have it.

Alien life may exist without conditions like Earth
