Gravity Could Be Source of Sustainable Energy

Researcher in the Netherlands believes even gravity can be harnessed to produce free electricity on a scale sufficient to power small appliances.

Kenya is splitting

A tear opens up in Kenya's Rift Valley. Geologists say it will - in a few million years - lead to the continent splitting in two.

Stanford researchers develop brain-controlled typing for people with paralysis

A clinical research publication led by Stanford University investigators has demonstrated that a brain-to-computer hookup can enable people with paralysis to type via direct brain control at the highest speeds and accuracy levels reported to date.

Acoustic holograms

Researchers can create complex patterns in air and water using ultrasonic waves. By placing 3D printed plates in front of speakers, they can levitate water droplets and propel small objects.

Liquid metals propel future electronics

Science fiction is inching closer to reality with the development of revolutionary self-propelling liquid metals – a critical step towards future elastic electronics.

Paralyzed man uses his arms again

Scientists harnessed a man’s brain waves to help him move his paralyzed hand again.

A 3-D Material that Folds, Bends and Shrinks on its Own

Harvard researchers have designed a new type of foldable material that is versatile, tunable and self actuated. It can change size, volume and shape; it can fold flat to withstand the weight of an elephant without breaking, and pop right back up to prepare for the next task.

The 'Artificial Leaf'

An "artificial leaf" made by Daniel Nocera and his team, using a silicon solar cell with novel catalyst materials bonded to its two sides, is shown in a container of water with light (simulating sunlight) shining on it. The light generates a flow of electricity that causes the water molecules, with the help of the catalysts, to split into oxygen and hydrogen, which bubble up from the two surfaces.

Invisibility cloak invented by Texas scientist Ali Aliev's video

Ali Aliev, the researcher have created a working invisibility cloak using one of nature's common yet bizarre phenomena -- the "mirage effect."In a video posted to YouTube, the strands are seen appearing and disappearing during a demonstration in Mr Aliev's lab.

Frozen smoke

UCF researchers have discovered a way to infuse the world's lightest carbon material with nanotubes. The results may lead to advances in robotic surgery, the detection of pollutants and even increase battery capacity!

NASA | Terrestrial gamma-ray flashes create antimatter

NASA's Fermi Gamma-ray Space Telescope has detected beams of antimatter launched by thunderstorms. Acting like enormous particle accelerators, the storms can emit gamma-ray flashes, called TGFs, and high-energy electrons and positrons. Scientists now think that most TGFs produce particle beams and antimatter.

Quantum levitation

Tel-Aviv University demos quantum superconductors locked in a magnetic field. For an explanation of the physics behind this demonstration, visit
