Phys.org / Grasslands could lose four times more carbon uptake under future drought conditions
The effects of individual climate factors on ecosystems are usually considered in isolation. However, in reality, they occur simultaneously and influence each other. Increasing CO2 concentrations in the atmosphere contribute ...
Phys.org / The largest digital camera ever built begins decade-long survey of the universe
The largest digital camera ever built is starting to capture images of unseen corners of the universe.
Phys.org / Layered ZnPS₃ emits single photons, opening new path for quantum chips
Scientists from the Faculty of Physics at the University of Warsaw, in collaboration with teams from the National University of Singapore and Radboud University in the Netherlands, have observed single-photon emission from ...
Phys.org / Loss of DNA protector gene exposes vulnerabilities in cancerous cells
Every time a cell copies its DNA, parts of the genome are exposed and vulnerable to damage or errors. Molecular biologist Simon Boulton is interested in how cells spot and repair damage to their DNA, and what happens if this ...
Phys.org / Computer scientists develop a new AI tool that rivals AlphaFold 3 in mapping RNA
The same family of artificial intelligence that powers today's image generators is now being aimed at one of biology's hardest puzzles: the ever-changing, three-dimensional shapes of RNA. These are the molecules behind mRNA ...
Phys.org / Black locust deploys peptides to steer root bacteria into nitrogen fixation
Plants need nitrogen to grow. Many legumes meet this need through a symbiotic relationship: They harbor bacteria that fix atmospheric nitrogen and make it available to the plant. Until now, it was largely unclear how a perennial ...
Phys.org / Mice actively seek better views to make visual decisions, virtual reality experiments show
Animals don't experience the world passively. A hawk tilts its head to track prey. A person leans forward to read a sign. Scientists call this "active sensing": moving the body to gather better information. A specific version ...
Phys.org / Jellyfish reveal rapid repair system behind scar-free healing
A decade ago this summer, at the Marine Biological Laboratory, Jocelyn Malamy watched jellyfish cells "walk" toward each other to close a wound for the first time. An associate professor of molecular genetics and cell biology ...
Phys.org / Rice grown on the moon? Air-to-fertilizer technology helps rice grow in lunar soil simulant
Securing sustainable food supplies is a key challenge for long-term human exploration and potential habitation of the moon. The moon's soil contains no organic material, and essential plant nitrogen sources like ammonia and ...
Phys.org / Industrial-era pollution and warming reshape Tibetan lake after 1,000 years of climate swings
The Tibetan Plateau, together with the Hindu Kush–Karakorum–Himalaya region, has more snow and ice than any other region on Earth apart from the polar regions. As a result, this high-altitude region is particularly sensitive ...
Phys.org / 'Atomic zoom' brings gum disease bacteria into sharp focus
The technology at the center of the growing "resolution revolution" has again shown its value to scientists at Yale by revealing the secrets of gum disease.
Phys.org / The little red galaxies that may be sending us neutrinos
Peering far into the distant, high-redshift universe, the James Webb telescope has discovered an abundance of small red galaxies known as the Little Red Dots. From their observations, astronomers believe that at least some ...
