Phys.org / Compact vacuum ultraviolet laser may improve nanotechnology and power nuclear clocks
Physicists at the University of Colorado Boulder have demonstrated a new kind of vacuum ultraviolet laser that is 100 to 1,000 times more efficient than existing technologies of its kind. The researchers say the device could ...
Phys.org / Golden lancehead genome reveals how genes responsible for venom toxins evolved
A research team led by scientists at the Butantan Institute in São Paulo, Brazil, has completed the most extensive genetic sequencing of a jararaca viper to date. The focus of the study was the genome of the golden lancehead ...
Phys.org / Florida's most at-risk bat moves into safer artificial roosts
Finding bats in the attic or under roof tiles is no homeowner's idea of fun. But Florida's endangered bonneted bats have few natural options left. With a dwindling number of large, old trees with cavities—their preferred ...
Phys.org / Female aggression, not just mate choice, may speed mosquitofish speciation
A new study reveals that behavioral isolation between populations of Bahamas mosquitofish is driven primarily by the actions of females—not just through mating choice behaviors, but also through sometimes violent resistance. ...
Phys.org / Uncovering the hidden bacteria often mistaken for cholera
Scientists have created a genomic blueprint for Aeromonas bacteria, which can cause antibiotic-resistant diarrheal disease—with symptoms often misidentified as cholera—in humans and animals.
Phys.org / Artificial kinetochores take the pressure off aging chromosomes during meiosis
For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes becomes more prone to ...
Phys.org / Fluid simulation at unprecedented scale provides toolkit for fundamental physics and applied fluid engineering
What governs the speed at which raindrops fall, sediment settles in river estuaries, and matter is ejected during a supernova? These questions circle around one, deceitfully simple factor: the rate at which a fluid filled ...
Phys.org / Heavy water expands energy potential of carbon nanotube yarns
Researchers at The University of Texas at Dallas have developed a new electrolyte system that significantly boosts the energy-harvesting performance of twistrons, which are carbon nanotube yarns that generate electricity ...
Phys.org / Titanium complexes cleanly edit the core skeleton of highly stable organic compounds
Multi-titanium hydrides can selectively snip the strong structural bonds of stable organic molecules called pyridines, RIKEN researchers have shown. This discovery could guide designing catalysts for applications in multiple ...
Phys.org / Despite their contrasting reputations, bonobos and chimpanzees show similar levels of aggression in zoos
Chimpanzees have a reputation for being aggressive, while bonobos are often seen as their peaceful counterparts. This contrast has frequently been used to explain different sides of human nature. However, a new study by Utrecht ...
Phys.org / Astronomers capture birth of a magnetar, confirming link to some of universe's brightest exploding stars
Astronomers have for the first time seen the birth of a magnetar—a highly magnetized, spinning neutron star—and confirmed that it's the power source behind some of the brightest exploding stars in the cosmos. The finding ...
Phys.org / Ancient Filipino skeleton reveals a rare hip condition further complicated by scurvy
The growing paleopathological literature shows that scurvy was not a rare problem among people living in the ancient Asia-Pacific tropics. Scurvy is increasingly identified throughout the region, primarily in children but ...
