Image: ISS transits the sun

Humankind's most distant outpost was recently captured crossing the face of our enormous and gleaming sun. The fleeting transit of the International Space Station was over in the blink of an eye, but Ian Griffin, Director ...

Lightning's electromagnetic fields may have protective properties

Lightning was the main electromagnetic presence in the Earth's atmosphere long before the invention of electricity. There are some 2,000 thunderstorms active at any given time, so humans and other organisms have been bathed ...

Using water molecules to unlock neurons' secrets

Neurons are brain cells that communicate with each other by sending electrochemical signals along axons. When a neuron is about to release a signal in the form of an electric charge, it allows ions to pass through its membrane ...

Electron sandwich doubles thermoelectric performance

Researchers more than doubled the ability of a material to convert heat into electricity, which could help reduce the amount of wasted heat, and thus wasted fossil fuel, in daily activities and industries.
