Phys.org / Ochre discovery in South African cave reveals advanced toolmaking during the Middle Stone Age
A new study from SapienCE reveals that early modern humans at Blombos Cave in South Africa used ochre as a specialized tool for stone toolmaking during the Middle Stone Age, demonstrating advanced technical skills far earlier ...
Phys.org / New 3D glacier visualizations provide insights into a hotter Earth
As glaciers retreat due to a rise in global temperatures, one study shows that detailed 3D elevation models could drastically improve predictions about how they react to Earth's warming climate.
Phys.org / Genomes reveal the Norwegian lemming as one of the most recently evolved mammal species
Using whole genome sequencing and cutting‐edge analyses, researchers at Stockholm University have uncovered the surprising evolutionary history of the Norwegian lemming (Lemmus lemmus), revealing it to be one of the most ...
Phys.org / Common farm fungicide may be contributing to 'insect apocalypse'
A widely-used agricultural chemical sprayed on fruits and vegetables to prevent fungal disease is also killing beneficial insects that play a critical role in pollination and wider ecosystems.
Phys.org / Southern Ocean saltier, hotter and losing ice fast as decades-long trend unexpectedly reverses
Researchers have discovered a dramatic and unexpected shift in the Southern Ocean, with surface water salinity rising and sea ice in steep decline.
Phys.org / Innovative clip-off chemistry enables fast and precise production of complex molecules
Researchers at the ICN2 and the UAB have developed a novel strategy to obtain different types of organic molecules by breaking down their molecular structures. This technique enables fast and precise production of these molecules ...
Phys.org / Webb refines Bullet Cluster mass and maps dark matter distribution
NASA's James Webb Space Telescope recently zeroed in on the Bullet Cluster—delivering highly detailed images that show a greater abundance of extremely faint and distant galaxies than ever before. Using Webb's crisp near-infrared ...
Phys.org / Mathematical approach makes uncertainty in AI quantifiable
How reliable is artificial intelligence, really? An interdisciplinary research team at TU Wien has developed a method that allows for the exact calculation of how reliably a neural network operates within a defined input ...
Phys.org / Extreme weather: AI-assisted early warning system offers targeted disaster prevention
AI can assist early warning systems that predict impacts of extreme weather events such as droughts and heavy rainfall.
Phys.org / Yellow bacterial pigment provides new insights into cellulose degradation for biofuels and antibiotics
Anaerobic bacteria were among the first life forms on Earth and existed at a time when there was no oxygen in the atmosphere. While many organisms depend on an oxygen-rich environment to survive, anaerobes thrive in places ...
Phys.org / AI pinpoints promising materials that capture only CO₂ from air
In order to help prevent the climate crisis, actively reducing already-emitted CO₂ is essential. Accordingly, direct air capture (DAC)—a technology that directly extracts only CO₂ from the air—is gaining attention. ...
Phys.org / New catalyst cuts precious palladium expenditure 100-fold by using recycled waste
Researchers have created a palladium-on-carbon catalyst for drug, pesticide, and plastic production that is very sparing in terms of precious metal use. In the new catalyst, palladium is carried on carbon particles manufactured ...
