Phys.org / Earth's hemispheres may have worked together to drive past ice ages
New research from the University of St Andrews has uncovered a previously unknown process that may have helped drive Earth into past ice ages. Published today (Oct. 22) in the Journal of Climate, the paper links ice sheets ...
Phys.org / Wildfires cause Amazon to emit 1.17 billion more metric tons of CO₂ than it absorbs
From 2010 to 2024, the Amazon rainforest—the largest tropical rainforest on the planet—released an average of 1.17 billion metric tons more carbon dioxide (CO₂) into the atmosphere than it absorbed each year. Wildfires were ...
Phys.org / The assumption about farm automation that may be wrong
You've likely heard this assumption: When AI-enabled and autonomous machines arrive on the farm, jobs will disappear. But researchers at the University of California, Davis, who studied 16 fruit tree operations in California ...
Phys.org / Algae-powered soft robot arm uses light to grasp and lift small objects
Tiny underwater algae sway gently in the current. All of a sudden, a light shines on them and they form robotlike arms that start to pick up small rocks and put them in floating baskets. Sounds like science fiction, but researchers ...
Phys.org / Public health programs can 'rewire' social networks, study finds
An educational program intended to improve maternal and child health fundamentally altered the social fabric of the rural Honduran villages where it was implemented, a new Yale-led study finds. The findings, researchers say, ...
Phys.org / Schrödinger's penguin: One species, two contrasting outcomes
A new University of Otago—Ōtākou Whakaihu Waka study reveals two vastly different life courses for one of Aotearoa New Zealand's least-studied penguin species.
Phys.org / Baby manta rays hunker down close to coasts before facing the open ocean's dangers
Giant manta rays can grow up to nine meters (30 feet) long with a disk size of seven meters (23 feet) across and weigh up to 2,000 kg (4,400 pounds). This size leaves them with very few natural enemies once they reach adulthood ...
Phys.org / Natural forest regeneration helps curb spread of invasive species
The presence of non-native trees is often seen as an obstacle to the recovery of tropical forests regrowing in previously deforested areas. To better understand the behavior of these plants over time in both humid and dry ...
Phys.org / Curtain-like plasma structures explain solar jets' apparent spinning in simulations
An international team of scientists from the University of Sheffield and the Indian Institute of Astrophysics, led by a postdoctoral research fellow from the University of Newcastle, Australia, has discovered that solar jets ...
Phys.org / Microplastics in sediment could trace decades of human activity worldwide
In a review article recently published in the journal Earth-Science Reviews, researchers from the Leibniz Institute for Baltic Sea Research Warnemünde (IOW), in collaboration with colleagues from the University of Leicester ...
Phys.org / Diamond laser system achieves 100% optical contrast in magnetic-field readout
Researchers at Fraunhofer IAF have developed a laser-enhanced quantum sensor that combines high magnetic-field sensitivity with a large dynamic range. Using laser threshold magnetometry, they improved the ratio of sensitivity ...
Phys.org / Amino acid stabilizes material's quantum state above room temperature
New research started with a special material that behaves unusually when it's extremely cold—135 degrees below zero Fahrenheit (minus 93 degrees Celsius), close to the most frigid temperature ever recorded in Antarctica—and ...
