Drawing inspiration from the plant world, researchers have invented a new electrode that could boost our current solar energy storage by an astonishing 3,000 percent.
The technology is flexible and can be attached directly to solar cells - which means we could finally be one step closer to smartphones and laptops that draw their power from the Sun, and never run out.
Black holes are among the most fascinating objects in the known Universe. But despite the fact that they're suspected to lurk at the centre of most galaxies, the reality is that no one has ever been able to actually photograph one.
That's because black holes, as their name implies, are very, very dark. They're so massive that they irreversibly consume everything that crosses their event horizon, including light, making them impossible to photograph....
While other noble gas elements have shown signs of forming compounds under extreme pressure, helium has remained firmly exclusive - until now. Scientists report creating what appears to be a stable helium-sodium compound, and it challenges some of the most basic assumptions of modern chemistry.
By subjecting molecular hydrogen, a gas, to ungodly pressures higher than those found at the Earth’s core, Harvard researchers have accomplished the impossible: they’ve turned the lightest element into a metal. This is now the rarest and possibly the most expensive material on the planet. This may soon change as metal hydrogen moves from the stuff of alchemy to a critical resource in mankind’s quest of becoming an interstellar species.
Stephen Hawking was the first to propose that not everything that comes in contact with a black hole succumbs to its immense gravity and inevitable nothingness. In fact, tiny particles of light, known as photons, are sometimes ejected back out of the black hole, robbing it of energy. This gradual loss of mass over time means that every black hole eventually evaporates out of existence.
