Phys.org / Centuries of net-negative emissions are required to secure a safe climate future, two studies suggest
Two new studies conclude that stabilizing long-term climate risks will require sustained net-negative carbon dioxide (CO₂) emissions for centuries. Approaching the problem from distinct perspectives—legal and technological ...
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 / Simulations suggest a breakthrough in understanding how turbulence develops
A new study revisits a century-old question about how turbulence starts. The findings could potentially influence not only aircraft engineering but even the design of mechanical heart valves, and treatment of heart disease. ...
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 / 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 / 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 / Oval orbit casts new light on black hole–neutron star mergers
Scientists have uncovered the first robust evidence of a black hole and neutron star crashing together but orbiting in an oval path rather than a perfect circle just before they merged. This discovery challenges long-standing ...
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 / Friendly fungi hijack plant regulator to promote symbiosis
Plants are constantly on guard. Their roots are equipped with molecular alarm systems that detect invading microbes and trigger immune responses. Yet beneficial soil fungi routinely enter living root cells and establish close ...
Phys.org / King penguins are the rare species benefiting from a warming world. But that could change
The warming world has disrupted the timing for plant and animal reproduction, and it's usually bad news for species that depend on each other—like flowers blooming too early and pollinating bees arriving too late. But researchers ...
