Phys.org / Ancient stardust grains were seeds for the earliest solids in the solar system
How did the first solids that made up planets, moons and asteroids form from the "hot soup" that characterized our solar system's earliest years? New research from Caltech analyzing pieces of a meteorite has found that, just ...
Phys.org / Mesolithic hunter-gatherers on Malta relied on repeated sea crossings, study suggests
The existence of humans on Malta, a tiny Mediterranean island, during the Mesolithic period is puzzling. Archaeological evidence indicates that foragers occupied the Maltese islands between 8,500 and 7,500 years ago, and ...
Phys.org / Chicken kidney sponge could be 'outstanding' at cleaning up polluted ports
Ports rank among the most disturbed marine environments. Pollutants like trash, oil and toxins from antifouling paints tend to accumulate in enclosed harbors. Invasive species arriving in ballast water may displace native ...
Phys.org / Psychologist develops puzzle that can tell you how fast you think
A puzzle that can tell players how fast they think on their feet has been developed by a University of Leeds researcher.
Phys.org / Ancient smallpox genomes reveal how European colonization brought the disease to the Americas
Researchers from Trinity College Dublin have recovered and analyzed the first ancient smallpox virus genomes ever identified in the Americas, providing the strongest direct evidence to date that the disease was introduced ...
Phys.org / A successful, sustainable catalyst for ethanol dehydrogenation
Ethanol is an alcohol used in a vast number of industrial and household applications. When dehydrogenated—in this case, stripped of some of its hydrogen atoms—it yields another important compound: acetaldehyde, which is used ...
Phys.org / Single molecule becomes quantum sensor for imaging proteins at nanoscale
A new quantum sensing technique could enable measurements of single protein structures and other important molecules, with potential applications in drug discovery and structural biology. A research team from the Institute ...
Phys.org / 100% organic free-range egg production could have negative consequences for climate and nature
A study published in Royal Society Open Science reveals striking trade-offs when it comes to different methods of egg production. Using UK data, the study compared several possible scenarios for the egg industry, including ...
Phys.org / Ancient Chinese seeds spanning 5,000 years train AI to ease archaeology's specialist bottleneck
Ancient plant seeds provide important archaeological evidence for studying the evolution of human civilization. Lingnan University and Shandong University have jointly developed the world's first artificial intelligence (AI) ...
Phys.org / Pacific Ocean pattern helps explain diverging wildfire trends in US and Australia
Two of the world's most fire-prone regions have followed strikingly different wildfire trajectories despite both experiencing a warming climate. Burned forest area has surged across the U.S. Southwest, while eastern Australia ...
Phys.org / One of industry's toughest lignin byproducts could become feedstock for valuable chemicals
The pulp and paper industry, which manufactures everything from tissue paper to cardboard, also generates a significant yet often overlooked byproduct—a complex polymer called lignin. Around 100 million tons of lignin are ...
Medical Xpress / AI blood assay detects liver cancer across diverse international populations
Researchers at the Johns Hopkins Kimmel Cancer Center validated an artificial intelligence (AI)-powered blood test that accurately detected liver cancer in people from two geographically and biologically distinct populations ...
