Electrons slide through the hourglass on surface of bizarre material
A team of researchers at Princeton University has predicted the existence of a new state of matter in which current flows only through a set of surface channels that resemble an hourglass. These channels are created through the action of a newly theorized particle, dubbed the “hourglass fermion,” which arises due to a special property of the material...

CMS releases new batch of research data from LHC
Today, the CMS Collaboration at CERN has released more than 300 terabytes (TB) of high-quality open data. These include over 100 TB, or 2.5 inverse femtobarns (fb−1), of data from proton collisions at 7 TeV, making up half the data collected at the LHC by the CMS detector in 2011. This follows a previous release from November 2014, which made available around 27 TB of research data collected in 2010.

Even Stephen Hawking sometimes turns out to be wrong. Who better to put him right than himself?
Are black holes bald or hairy? On that strange and esoteric question may hang the future of the universe’s past. The present, the past and the future are all connected by physical laws, a phenomenon called “causal determinism”. With complete information about a system’s present, it ought therefore be possible to determine all its past and future states. In theory, that applies to any system, up to and including the entire universe.

Is Particle Physics About to Crack Wide Open?
It’s December 15, 2015, and an auditorium in Geneva is packed with physicists. The air is filled with tension and excitement because everybody knows that something important is about to be announced. The CERN Large Hadron Collider (LHC) has recently restarted operations at the highest energies ever achieved in a laboratory experiment, and the first new results from two enormous, complex detectors known as ATLAS and CMS are being presented. This announcement has been organized hastily because both...

Physicists just confirmed a pear-shaped nucleus, and it could ruin time travel forever
Physicists have confirmed the existence of a new form of atomic nuclei, and the fact that it’s not symmetrical challenges the fundamental theories of physics that explain our Universe. But that's not as bad as it sounds, because the discovery could...
