Phys.org / Past CO₂ emissions may drive far bigger future economic losses
The economic damage yet to come from carbon dioxide emitted decades ago far exceeds the harm it has wrought so far, according to a new Stanford University study. The research, published in Nature, puts a dollar value on the ...
Phys.org / Using 'imaginative' AI to survey past and future earthquake damage
Researchers have used artificial intelligence to develop a new tool for assessing earthquake damage, a leap that could ultimately help first responders in making critical rescue decisions, suggests a new study. The team's ...
Phys.org / Significant grade inflation may be occurring in graduate education, according to decades' worth of data
Analysis of two decades of student data at a large U.S. university suggests that grade inflation exists in graduate education. Researcher Vivien Lee and colleagues at the University of Minnesota, U.S., present these findings ...
Phys.org / It's go time: historic Moon mission set for lift-off
More than half a century after the groundbreaking Apollo program's last crewed flight to the moon, three men and one woman are preparing for a lunar journey set to turn a new page in American space exploration.
Phys.org / Dancing to invisible choreography, quantum computers can balance the noise
Large-scale quantum computers are waiting in the wings. One of the main reasons we don't have them yet is because quantum hardware is so noisy. This isn't the type of noise you'd want to shush in a crowded theater. When it ...
Phys.org / Amazon wildfire emissions may be up to three times higher than estimated
Fires are a recurring phenomenon in central South America, often intensified by drought and deforestation. In 2024, wildfire activity reached its highest levels in 20 years, affecting vast areas of the Amazon rainforest and ...
Phys.org / Cactus catalog could help plant's prickly problem
With almost a third of cacti species threatened with extinction, a new open-access database of cactus ecology and evolution could help scientists and conservationists save species from the brink.
Phys.org / Why some reefs recover faster than others—mathematical model spotlights coral recruitment patterns
Climate-driven disturbances such as marine heat waves are rapidly reducing coral cover and degrading reef ecosystems worldwide. Using a mathematical model, a research team led by Subhendu Chakraborty at the Leibniz Center ...
Phys.org / Low-cost sensor system could warn farmers of salt stress in plants
Soil salinity is a critical concern in agriculture when excessive soluble salts restrict a plant's water uptake, according to the U.S. Department of Agriculture, hindering crop growth and reducing yields on roughly 30% of ...
Phys.org / Bioelectronic platform enables precise H₂S delivery to cells, turning a toxic gas into a therapeutic tool
A toxic gas known for its "rotten egg smell" has been transformed into a therapeutic tool. A research team at KAIST has developed a technology to precisely control hydrogen sulfide (H2S) using electrical signals, bringing ...
Phys.org / Stabilized hybrid photocatalyst boosts artificial photosynthesis efficiency
A hybrid photocatalyst system from Science Tokyo tackles an overlooked flaw in artificial photosynthesis to dramatically improve CO2-to-formate conversion. Unlike conventional designs where light degrades the molecular catalyst, ...
Phys.org / DNA origami precisely positions single-photon emitters for quantum technologies
An international research team led by scientists from Skoltech has developed a method to position molecules on the surface of ultrathin materials with unprecedented precision using molecular DNA self-assembly, enabling the ...
