An "Impenetrable Barrier" Protects The Earth From Killer Electrons

It appears that our planet's built-in force field is much stronger than we thought. Scientists studying the Van Allen belts have discovered the presence of a nearly impenetrable barrier that prevents some of the fastest and most powerful "ultrarelativistic" electrons from reaching the surface. » 11/27/14 1:00pm 11/27/14 1:00pm

Freakishly Compact Particle Accelerators Could Revolutionize Physics

Experiments at the SLAC National Accelerator Laboratory in the U.S. have taken us a step forward in developing a technology that could significantly reduce the size of particle accelerators and allow scientists to accelerate particles more rapidly than conventional accelerators at a much smaller size. » 11/06/14 2:20pm 11/06/14 2:20pm

Curious Signal Could Be Dark Matter Pouring From The Sun's Core

This could be historic: Astronomers from Leicester University have detected a strange signal in the X-ray spectrum that appears to be a signature of 'axions' — a hypothetical dark matter particle. It could take years to confirm, but this may be the first direct detection and identification of dark matter. » 10/17/14 8:00am 10/17/14 8:00am

Physics experiment suggests magnets with only one pole actually exist

Though predicted to exist, magnetic monopoles — hypothetical elementary particles with only one magnetic pole — have never been detected by scientists. But physicists have just accomplished the next best thing by actually creating their own synthetic version of these bizarre magnetic particles in the lab. » 1/31/14 9:00am 1/31/14 9:00am

New calculations suggest the Universe could collapse at any time

All things being equal, the universe is set to continually expand, eventually ripping itself to shreds in about 22 billion years. But Danish scientists say an expanding bubble of existential doom could crush the Universe into a tiny ball. And crazily, the odds of this collapse is higher than previously thought. » 12/13/13 12:40pm 12/13/13 12:40pm

Unprecedented neutrino discovery is a "Nobel Prize in the making"

By drilling a 1.5 mile hole deep into an Antarctic glacier, physicists working at the IceCube South Pole Observatory have captured 28 extraterrestrial neutrinos — those mysterious and extremely powerful subatomic particles that can pass straight through solid matter. Welcome to an entirely new age of astronomy. » 11/22/13 12:45pm 11/22/13 12:45pm
