Phys.org / Human activity has driven retreat of Antarctica's fastest melting glacier
Human-driven climate change significantly intensified the retreat of one of the most important glaciers in Antarctica during the 20th century. The Pine Island Glacier, which drains a large part of the West Antarctic Ice Sheet ...
Phys.org / Reanalysis suggests 'Phoebe' is a variable star, not a primordial black hole
A new study debunks a recent claim that astronomers may have detected a lunar-mass primordial black hole. In a reanalysis of observations from the Dark Energy Camera (DECam), researchers found that the star nicknamed "Phoebe" ...
Phys.org / Shining blue light on gold-graphene nanodots achieves wound healing trifecta
Closing wounds, burns and deep cuts isn't enough to kick-start healing. A wound needs a clean environment, free of bacterial infection and interruption. That calls for three components working together—one to kill bacteria, ...
Phys.org / Off-center stellar death points to wandering supermassive black hole stripped of its own galaxy
Astronomers have uncovered new details about the black hole that ripped apart a star in a tidal disruption event named AT2024tvd. Findings suggest it is a wandering supermassive black hole—the kind that is not located at ...
Phys.org / Injectable silk-kudzu hydrogel achieves complete wound closure in laboratory tests
Researchers at the Terasaki Institute for Biomedical Innovation have developed an injectable hydrogel, a water-based gel material, made from silk proteins and a plant-derived compound. In laboratory tests, the material promoted ...
Phys.org / NASA races to save Swift telescope from falling back to Earth with daring rescue mission
NASA is racing to save an aging telescope from falling back to Earth with a daring rescue mission.
Phys.org / Nanopattern method unlocks precise control of disorder for wave-guiding devices
A research team has developed a methodology to precisely design and control the "degree of disorder" in nanopattern arrays using metal-infiltrated block copolymer (BCP) thin films. The work was led by Professor So Youn Kim ...
Phys.org / Ancient algal defenses against UV may have helped plants conquer land
A new study sheds light on how the ancestors of modern land plants survived one of the most challenging aspects of life outside water: exposure to harmful ultraviolet (UV) radiation. By examining a microscopic alga closely ...
Phys.org / The sun's outbursts may briefly weaken rain and snow events across North America
For decades, scientists have searched for a clear link between the sun's explosive storms and the weather that occurs on Earth. A breakthrough study from the University of New Hampshire reveals that in the hours and days ...
Phys.org / World's largest particle smasher halts for upgrade to boost hunt for dark matter
The world's most powerful particle accelerator will shutter operations Monday for four years of renovations to dramatically boost its collision capacity and the potential for unlocking one of the greatest mysteries of the ...
Phys.org / Primate evolution kept aging rates stable for 25 million years despite lifespan gaps
Biologists group animals with similar traits into broad categories called orders. Despite their similarities, animal species in the same order can have very different average lifespans.
Phys.org / The bond between humans and dogs remains remarkably consistent across societies, cross-cultural study reveals
A new study by an international research team led by Friedrich Schiller University Jena and the Max Planck Institute for Evolutionary Anthropology (Leipzig) has revealed striking similarities in the way humans and dogs interact ...
