Eun-Ah Kim, professor of physics in the College of Arts and Sciences, and Google researchers report the first demonstration of two-dimensional particles, called non-Abelian anyons, that are the key in...
Once every 10,000 years or so, the center of a galaxy lights up as its supermassive black hole rips apart a passing star. This “tidal disruption event” happens in a literal flash, as the central black...
In the particle world, sometimes two is better than one. Take, for instance, electron pairs. When two electrons are bound together, they can glide through a material without friction, giving the mater...
Novel camera detects the birth of high-energy runaway electrons, which may lead to determining how to prevent damage caused by the highly energetic particles.
The Milky Way is surrounded by dozens of dwarf galaxies thought to be relics of the first galaxies in the universe. Among the most primitive of these galactic fossils is Tucana II -- an ultrafaint dwa...
Using a smartphone to detect norovirus(图)     smartphone  detect  norovirus       font style='font-size:12px;'> 2019/12/2
A little bit of norovirus -- the highly infectious microbe that causes about 20 million cases of food poisoning in the United States each year -- goes a long way. Just 10 particles of the virus can ca...
LIGO and Virgo detect neutron star smash-ups(图)     LIGO  Virgo  neutron star smash-ups       font style='font-size:12px;'> 2019/10/30
On April 25, NSF's Laser Interferometer Gravitational-Wave Observatory (LIGO) and the European-based Virgo detector registered gravitational waves from what appears to be a crash between two neutron s...
In August, detectors on two continents recorded gravitational wave signals from a pair of black holes colliding. This discovery, announced today, is the first observation of gravitational waves by thr...
Exploding stars lit the way for our understanding of the universe, but researchers are still in the dark about many of their features.A team of scientists, including scholars from the University of Ch...
Specifically, the two tuning nanoscatterers set the resonator at an "exceptional point," a special state of a system at which unusual phenomena may occur. The third nanoscatterer perturbs the system, ...
Scientists have found compelling evidence for a stratosphere on an enormous planet outside our solar system. The planet’s stratosphere—a layer of atmosphere where temperature increases with higher alt...
Using the supersharp radio “vision” of the National Science Foundation’s Very Long Baseline Array (VLBA), astronomers have made the first detection of orbital motion in a pair of supermassive black ho...
Maternal hypothyroxinemia secondary to iodine deficiency may have neurodevelopmental effects on the specific neurocognitive domain of memory. Associated disruption of thyroid hormone–dependent protein...
New research led by astrophysicists at York University has revealed the fastest winds ever seen at ultraviolet wavelengths near a supermassive black hole.“We’re talking wind speeds of 20 per cent the ...
Pioneering effort to detect Ebola     Pioneering  Ebola       font style='font-size:12px;'> 2015/12/14
According to the World Health Organization, the Ebola outbreak that started in West Africa in 2014 has sickened nearly 30,000 people, killing about one third of them. Detection of the Ebola virus is c...
