Phys.org / Jellyfish nebula may be the scene of two stars going supernova
The star that formed the Jellyfish nebula may have had a partner star that exploded 100,000 years earlier, according to international researchers, who say that this may be the first known discovery of a binary star system ...
Phys.org / Two-color lasers aim electron currents through semiconductor with no electric field
Researchers at the University of Michigan have created a device that enables them to control the flow of electrons through a semiconductor using only laser light—no electrical power source required. The device was built to ...
Phys.org / New technique enables LIGO to peer farther into the distant universe
Scientists at the University of California, Riverside, have developed a new way to help gravitational-wave observatories see farther into the universe by solving one of their biggest challenges: tiny heat-induced distortions ...
Phys.org / Mysterious gas 'bullets' race from Milky Way's only known helium nova at up to 20 million mph
Mysterious high-speed "bullets"—clumps of possibly oxygen-rich gas traveling at up to 20 million miles per hour—have been discovered shooting out of the rarest stellar explosion in our galaxy.
Phys.org / Animals in prehistoric paintings reveal hidden pattern across nine Basque caves
Iñaki Intxaurbe, a researcher at the EHU-University of the Basque Country, analyzed the distribution of images in nine caves in the Basque Country using network-based analysis and statistical techniques.
Phys.org / Simulations show distinct ground motion signatures of supershear earthquakes
Sustained supershear earthquake ruptures produce distinct ground-motion characteristics compared with subshear earthquakes, according to a study published in the Bulletin of the Seismological Society of America, with potential ...
Phys.org / Atomic channels can separate rare earth elements from each other without using toxic chemicals
Rare earth elements like lanthanum, neodymium and dysprosium are used to build the electric motor in your car, the LED lights in your house and the MRI machine at your doctor's office. But first, they have to be mined and ...
Phys.org / Birds flying in 'V' formation save energy with flatter flaps, new research shows
Scientists have known for years that birds like geese and ibises gain an aerodynamic advantage from flying in a "V" formation. Now, researchers from Brown University have provided new insights into the nature of that advantage.
Phys.org / Zoo elephant survival has improved substantially over 6 decades, international study finds
Elephants living in modern zoos are living significantly longer than they did half a century ago, according to a study published in the journal Scientific Reports. The research—led by ZSL (the Zoological Society of London) ...
Phys.org / New study into humans' closest ape relatives suggests physical touch can promote social harmony
Physical touch may be an important evolutionary tool to help manage social tension and keep the peace. That is according to a new study led by Durham University in the UK, analyzing behaviors of our closest ape relatives, ...
Phys.org / New radio-burst method helps locate universe's missing ordinary matter
Stars and galaxies make up much of the universe's ordinary, observable matter. But for decades, scientists have wrestled with a cosmic conflict: There should be much more.
Phys.org / Students unearth rare, centuries-old pot at Florida Spanish mission site
Some 400 years ago, a member of the Indigenous Potano-Timucua tribe scooped up some clay and carefully molded it into a modest vessel, small enough to rest in the palm of their hand. You can imagine their fingers pressing ...
