Phys.org / Experiment observes quantum radiation reaction as electrons hit an ultra-intense laser
For the first time, a quantum radiation reaction in strong electromagnetic fields has been demonstrated experimentally by allowing electrons to collide with an extremely intense and powerful laser beam. The research findings ...
Phys.org / Physicists trace the sun's magnetic engine, 200,000 kilometers below its surface
Every eleven years, the sun's magnetic field flips. Sunspots—dark, cooler regions on the sun's surface that mark intense magnetic activity and often trigger solar eruptions—appear at mid-latitudes and migrate toward the ...
Phys.org / Models warn Thwaites Glacier could rival entire Antarctic ice loss by 2067
The future of one of Antarctica's most iconic glaciers could be far more dramatic than scientists previously thought. Using satellite calibrated ice sheet models, a team of researchers from the University of Edinburgh found ...
Medical Xpress / Stem cell therapy shows promise for reversing aging-related frailty in new clinical trial
Stem cells are gaining attention for their potential to treat leukemia, certain solid tumor cancers, and inherited metabolic disorders. Now, a clinical trial reports that a single dose can significantly improve physical strength ...
Phys.org / Natural textile fibers may persist for more than a century in lake sediments
Natural fibers promoted as sustainable alternatives to plastic, including cotton and wool, have been found preserved in a U.K. lake for more than a century—challenging assumptions that they quickly biodegrade in the environment. ...
Phys.org / Globular cluster NGC 5824 is embedded in a dark matter halo, study suggests
Using data from the Magellan Clay telescope and the Canada-France-Hawaii Telescope (CFHT), astronomers have investigated a galactic globular cluster known as NGC 5824. Results of the new study, available in a paper published ...
Phys.org / Do political social media ads influence the outcome of elections?
Social media platforms, such as Facebook, Instagram and X, are accessed daily by millions of people worldwide. In the weeks or months leading up to elections, many political parties use social media platforms as part of their ...
Tech Xplore / Compostable robot endures over 1 million uses before becoming plant food
The rapid proliferation of robots and electronic devices is placing the world under a new and growing environmental burden. According to the United Nations Institute for Training and Research (UNITAR), global electronic waste ...
Phys.org / Nest-building birds help disperse cotton further than wind, study suggests
Birds play a larger role in the dispersal of wild cotton than previously assumed. This is shown by a study in the journal Oikos, carried out in southern Africa. Researchers discovered that birds actively collect wild cotton ...
Phys.org / Ultrafast laser pulses bring diamond-based quantum internet closer to reality
The controlled generation of single photons is an essential element of numerous quantum technology applications, such as quantum networks and quantum computing. A research team has now demonstrated the successful application ...
Phys.org / Asteroid Bennu's rugged surface baffled NASA—now, we finally know why
In one of the biggest surprises of NASA's OSIRIS-REx mission, its target asteroid, Bennu, turned out to be a jagged, rugged world covered in large boulders, with few of the smooth patches that earlier observations from Earth-based ...
Phys.org / Turning mosquitoes into flying vaccine carriers to protect against bat-borne viruses
Bats are reservoirs for several zoonotic viruses, such as Ebola and coronaviruses. These pathogens can spread to humans through direct contact with the flying mammals or their bodily fluids, or indirectly through contaminated ...
