If you throw a particle at a wall, there’s a chance that it will suddenly appear on the other side. This is thanks to a phenomenon known as quantum tunneling, and now a team of physicists has measured just how long that process takes.

Particle accelerators have plenty to teach us, but these facilities involve kilometers of tunnels and equipment. Now, researchers at Imperial College London have developed a new way to accelerate antimatter particles using common equipment already found in many labs, in a much smaller space.

NOAA flew a scientific aircraft right through Hurricane Patricia in 2015. Now, the researchers have reported their findings, including the detection of a beam of antimatter being blasted towards the ground, accompanied by flashes of x-rays and gamma rays.

As tiny as they are, there's a relatively large amount of empty space inside an atom. Now, scientists from Austria and the US have filled in some of those gaps, creating a new state of matter in the form of "giant atoms" filled with other atoms.

The world’s most powerful X-ray laser, the Linac Coherent Light Source (LCLS), is about to get far more powerful. The first of 37 “cryomodules” has arrived at Stanford University’s SLAC National Accelerator Laboratory, which will boost the speed and power of the facility.

To better understand molecular events, scientists use short-pulse X-ray lasers to take precise snapshots. Now, researchers at ETH Zurich have managed to shorten the pulse of an X-ray laser down to 43 attoseconds – which the team says is the shortest controlled event ever created by humankind.

In quantum physics particles can tunnel through barriers that they shouldn’t normally be able to. While this process, called quantum tunneling, is well documented, physicists haven’t been able to tell if it happens instantly or takes time, but now a team from the Max Planck Institute has an answer.

Researchers at Imperial College London have surprised everyone with research suggesting that binding light to a single electron could result in a new type of light that boasts the properties of both light and electricity.

An international team of researchers has found a way to control the spin of electrons – from a normal state to excited and back again – in a silicon-based material. The scientists believe their work holds promise for quantum computing as well as improved magnetic resonance imaging.
