Dark energy: Q&A with Steve Kuhlmann
Why do we care about dark energy in the first place?
Invisible volcanic ash gives clues to Neanderthal demise
(Phys.org) -- Invisible to the human eye, cryptotephra is a fine volcanic glass that is blasted out of erupting volcanoes along with ash. It leaves behind a hidden layer, in the earth, which has now been detected, ...
Electromagnetic 'swamps' don't always bog electrons down
Scientists have designed a simple system to study how electrons travel through energy barriers instead of over them.
A comprehensive study of ice
A group composed of 17 scientists from 11 different countries has published the most comprehensive study ever done on ice in the world. The study addresses the most important contemporary issues in a field ...
Einstein was right, neutrino researchers admit
Scientists on Friday said that an experiment which challenged Einstein's theory on the speed of light had been flawed and that sub-atomic particles -- like everything else -- are indeed bound by the universe's ...
Spin structure reveals key to new forms of digital storage, study shows
A synthetic compound long known to exhibit interesting transition properties may hold the key to new, non-magnetic forms of information storage, say researchers at the RIKEN SPring-8 Center and their collaborators. ...
Revealed: The fish that nearly sank Isaac Newton
A 300-year-old drawing of a flying fish that nearly scuttled Isaac Newton's world-changing opus on modern physics will be showcased in the Royal Society's online picture library, launched Thursday.
Physicists continue work to abolish time as fourth dimension of space
Italian physicist behind 'faster-than-light' test resigns
An Italian physicist at the head of a team that made a cautious but hugely controversial claim that neutrinos may travel faster than the speed of light resigned on Friday following calls for his dismissal.
Looking at quantum gravity in a mirror
Einstein's theory of gravity and quantum physics are expected to merge at the Planck-scale of extremely high energies and on very short distances. At this scale, new phenomena could arise. However, the Planck-scale ...
Researchers send 'wireless' message using neutrinos
(PhysOrg.com) -- A group of scientists led by researchers from the University of Rochester and North Carolina State University have for the first time sent a message using a beam of neutrinos nearly ...
Tech giants get lecture on perils of gadget worship
Silicon Valley giants at the prestigious TED innovation conference here on Tuesday were warned that the worship of technology will ruin the world before it saves it.
Pulsars: The Universe's gift to physics
Pulsars, superdense neutron stars, are perhaps the most extraordinary physics laboratories in the Universe. Research on these extreme and exotic objects already has produced two Nobel Prizes. Pulsar researchers now are poised ...
Rice's 'quantum critical' theory gets experimental boost
New evidence this week supports a theory developed five years ago at Rice University to explain the electrical properties of several classes of materials -- including unconventional superconductors -- that ...
