Phys.org / Room-temperature laser hits record stability with 68-cm optical cavity
Scientists at NPL have demonstrated the best-reported laser frequency stability achieved with an optical reference cavity operating at room temperature, marking a major advance in ultrastable laser technology. The team's ...
Phys.org / How longer exciton lifetimes could ease efficiency trade-off in organic solar cells
Although the efficiency of organic solar cells has now risen to more than 20%, there are physical limits that make it difficult to further increase their performance. A research team from Linköping University in Sweden, the ...
Phys.org / Nearly isotropic superconducting property revealed in trilayer nickelate
A research team led by Prof. Zhang Jinglei from Hefei Institutes of Physical Science, Chinese Academy of Sciences, found that the trilayer nickelate La4Ni3O10-δ exhibits a nearly isotropic upper critical field under high ...
Phys.org / Solar blast's magnetic cloud grew by one-fifth en route to Earth, spacecraft reveal
A University of Iowa-led physics team has detailed the extreme expansion of a magnetic cloud that originated from a huge, gaseous explosion on the sun. In a new study, the researchers describe the inflated magnetic cloud ...
Phys.org / El Niño is underway, satellite observations show
El Niño, characterized by warmer-than-normal water temperatures in parts of the equatorial Pacific, made its return in June 2026. Observations of sea surface height from the Sentinel-6 Michael Freilich satellite that month ...
Medical Xpress / Clues to psilocybin's epigenetic effects on people with alcohol use disorder
Some psychedelics, psychoactive substances that alter people's mood, perceptions and mental processes, were recently found to be promising alternative treatments for some mental health disorders. The substance that has attracted ...
Tech Xplore / New bacteria-based cooling material could help electronics and EV batteries run cooler
Next-generation electronic devices like newer computers and other high-power devices require more energy to run. When they are working hard, the intense heat they generate can limit their performance and reliability. That's ...
Phys.org / Web archive lets you easily search millions of government documents
At the end of every presidential term, the End of Term Web Archive preserves that administration's web presence as a vast trove of documents and webpages. The archive began in 2008, with George W. Bush's second term, and ...
Phys.org / Extreme heat is harming remote First Nations communities. It's time we listen to them
In remote Australia, First Nations communities battle extreme heat each summer. In January 2026 alone, the town of Alice Springs (Mparntwe) endured 20 days of temperatures above 40°C (104°F). This prolonged heat wave—defined ...
Phys.org / A nanotrap for HIV: Liposomes repurposed to trigger immune response
Medical advancements over the last several decades have made great strides in the treatment of HIV. Pharmaceutical treatments are able to contain and reduce a patient's viral load to the point where it is nearly undetectable. ...
Tech Xplore / Light-controlled microgripper bridges the gap between precision and force
For some time, researchers have used optical tweezers to manipulate tiny objects with incredible precision, using carefully controlled beams of laser light. So far, however, this technique has always come with strict limits ...
Phys.org / Does the Netherlands feed the world? Study challenges a familiar view of Dutch agriculture
The Netherlands is a major agricultural exporter. But look beyond euros to land, animal feed, calories and protein, and a different picture emerges. In a study published in Nature Food, researchers at Wageningen University ...
