Phys.org / 2.8 days to disaster: Why we are running out of time in low earth orbit
A "House of Cards" is a wonderful English phrase that it seems is now primarily associated with a Netflix political drama. However, its original meaning is of a system that is fundamentally unstable. It's also the term Sarah ...
Phys.org / Rare brown dwarf discovered orbiting ancient star
Astronomers from the Harvard-Smithsonian Center for Astrophysics (CfA) and elsewhere report the discovery of a new brown dwarf about 60 times more massive than Jupiter. The newfound substellar object, designated TOI-7019 ...
Phys.org / Male bees' food begging behavior traced to a single genetic factor
Is complex social behavior genetically determined? Yes, as a team of biologists from Heinrich Heine University Düsseldorf (HHU) together with colleagues from Bochum and Paris discovered while studying bees.
Medical Xpress / Chronic cannabis use, vomiting and compulsive bathing—symptoms of a hidden syndrome
Researchers at the Jane Addams College of Social Work at the University of Illinois Chicago have found that cannabinoid hyperemesis syndrome, a vomiting condition tied to chronic cannabis use, rose sharply in US emergency ...
Phys.org / Nobel Prize for missing piece in neutrino mass puzzle (Update)
Two scientists won the Nobel Prize in physics Tuesday for key discoveries about a cosmic particle that whizzes through space at nearly the speed of light, passing easily through Earth and even your body.
Phys.org / Sea reptile's tooth shows that mosasaurs could live in freshwater
Mosasaurs, giant marine reptiles that existed more than 66 million years ago, lived not only in the sea but also in rivers. This is shown by new research based on analyses of a mosasaur tooth found in North Dakota and believed ...
Phys.org / Long-hypothesized dynamic transition seen in deeply supercooled water for the first time
In a new study published in Nature Physics, researchers have achieved the first experimental observation of a fragile-to-strong transition in deeply supercooled water, resolving a scientific puzzle that has persisted for ...
Phys.org / Scientists demonstrate first color-tunable and first graphene-based LED
(Phys.org)—Currently, all light-emitting diodes (LEDs) emit light of only one color, which is predefined during fabrication. So far, tuning the color of light produced by a single LED has never been realized, despite numerous ...
Phys.org / Cats adjust their communication strategy by meowing more when greeting men
As many cat owners will testify, their pets are often mysterious creatures, independent, cunning and sometimes aloof. And now it appears that when it comes to communication, they might be playing favorites. A new study published ...
Phys.org / East Antarctic Ice Sheet's history tells a relevant story for today and beyond
Though ice sheet melting is widely talked of and debated, there is limited knowledge about what happens after the period of melting. Researchers dig into this "after" period and see how it relates to previous patterns.
Phys.org / Scientists grow high-quality graphene from tea tree extract
(Phys.org)—Graphene has been grown from materials as diverse as plastic, cockroaches, Girl Scout cookies, and dog feces, and can theoretically be grown from any carbon source. However, scientists are still looking for a ...
Phys.org / Blind quantum computing method surpasses efficiency 'limit'
(Phys.org)—Demonstrating that limits were made to be broken, physicists have overcome what was previously considered to be a natural and universal limit on the efficiency of a quantum cryptography task called blind quantum ...
