Phys.org / A photon that challenges Einstein: According to current physics, it should never have reached Earth
How did a photon survive a journey of more than 2 billion light-years when, according to known physics, it should have been absorbed long before reaching Earth? This is the question at the heart of a new study by Giorgio ...
Phys.org / Levitated magnet opens new frontier in search for ultraheavy dark matter
Rice University researchers have used a magnetically levitated particle to search for ultraheavy dark matter, extending the hunt for some of the heaviest possible forms of the invisible matter thought to hold galaxies together. ...
Dialog / A black hole as light as 40 tons can exist inside a star if dark matter helps
In 1974, Stephen Hawking made a prediction that transformed our understanding of black holes. Black holes, he showed, are not truly black: They slowly lose energy through a quantum process now known as Hawking radiation. ...
Medical Xpress / Should adults with autoimmune rheumatic conditions receive updated COVID-19 vaccines?
In an Arthritis & Rheumatology analysis of data on 60,980 U.S. adults with autoimmune rheumatic conditions who developed COVID-19 between December 2020 and August 2024, those who received booster or updated (2023–2024) COVID-19 ...
Phys.org / Plants' response to rising CO₂ could put the brakes on dryland expansion
Drylands are defined as regions where rainfall is low relative to the atmosphere's ability to draw water from soil and plants. Expanding boundaries of these regions are frequent concerns in climate change considerations. ...
Phys.org / Stripped-down LSD reveals structural features linked to hallucinogenic and therapeutic effects
University of California, Davis, researchers have stripped down LSD to the base features responsible for its hallucinogenic and therapeutic effects.
Medical Xpress / A single IV treatment retrains immune cells to fight autoimmune diseases in early trial
CAR T-cell therapy is an immune-reprogramming procedure that turns a patient's own immune cells into cancer-fighting specialists. The entire process is complex, but researchers have now found a faster way to achieve similar ...
Phys.org / Big supernova dataset challenges dark energy theory
The most comprehensive catalog of exploding white dwarf stars ever assembled has revealed new clues about dark energy, the mysterious force driving the universe's accelerating expansion. Researchers at The University of Queensland's ...
Phys.org / A vicarious calibration model enables quantitative applications of Fengyun-3 satellite ocean color data
Ocean color remote sensing is a vital tool for monitoring global ocean carbon sinks and primary productivity. However, the on-orbit calibration accuracy of satellite sensors is insufficient, and weak marine signals account ...
Phys.org / A new game demonstrates quantum advantage with provable classical limits
For decades, physicists have worked to prove the strange predictions of quantum mechanics with real experiments. As quantum computers have grown more powerful, researchers have devised increasingly sophisticated ways to test ...
Phys.org / Beyond the sea walls: Underwater archaeology reveals the hidden scale of ancient Mediterranean ports
Trade routes and ports have shaped the history of human civilization, with the Mediterranean network among the most prominent and influential. Yet our understanding of its past is shaped largely by what remains visible on ...
Medical Xpress / How music helps the stressed brain bounce back
You've had a tough day and want nothing more than to flop on the sofa and listen to some soothing music. After a few minutes, you feel peaceful and calm. Anecdotally, music has long been known to relieve stress, but the scientific ...
