Hackers begone: Measurement-device-independent QKD increases clock rate and transmission distance while reducing failure
Spontaneous wave function collapse can suppress acoustic Schrodinger cat states
A Higgs-gravity connection may leave traces in white dwarfs
Climate models don't over-predict warming, study shows
If you listen to climate change skeptics, Earth's surface hasn't warmed appreciably in the last 15 years, and any "record" set last year is just the result of the planet doing what the planet naturally does.
Quantum computer as detector shows space is not squeezed
Ever since Einstein proposed his special theory of relativity in 1905, physics and cosmology have been based on the assumption that space looks the same in all directions - that it's not squeezed in one direction ...
Best of Last Week – Setting a quantum speed limit, slowing the speed of light and turning back the aging clock
Is the Higgs boson a piece of the matter-antimatter puzzle?
(Phys.org) —Several experiments, including the BaBar experiment at the Department of Energy's SLAC National Accelerator Laboratory, have helped explain some – but not all – of the imbalance between ...
Molecular 'hats' allow in vivo activation of disguised signaling peptides
When someone you know is wearing an unfamiliar hat, you might not recognize them. Georgia Institute of Technology researchers are using just such a disguise to sneak biomaterials containing peptide signaling ...
Researchers use real data rather than theory to measure the cosmos
For the first time researchers have measured large distances in the Universe using data, rather than calculations related to general relativity.
Physicists explain puzzling particle collisions
An anomaly spotted at the Large Hadron Collider has prompted scientists to reconsider a mathematical description of the underlying physics. By considering two forces that are distinct in everyday life but ...
LHCb experiment observes two new baryon particles never seen before
(Phys.org) —Today the collaboration for the LHCb experiment at CERN's Large Hadron Collider announced the discovery of two new particles in the baryon family. The particles, known as the Xi_b'- and Xi_b*- ...
Gravity may have saved the universe after the Big Bang, say researchers
(Phys.org) —New research by a team of European physicists could explain why the universe did not collapse immediately after the Big Bang.
Study suggests warmth, flowing water on early Mars were episodic
Ample evidence of ancient rivers, streams, and lakes make it clear that Mars was at some point warm enough for liquid water to flow on its surface. While that may conjure up images of a tropical Martian paradise, ...
Granular model explains unusual behavior in sand
From a mechanical perspective, granular materials are stuck between a rock and a fluid place, with behavior resembling neither a solid nor a liquid. Think of sand through an hourglass: As grains funnel through, ...
