Phys.org / Laser-based 3D imaging system enables precise detection and quantification of methane leakage
A research team led by Prof. Zhang Zhirong from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a high-performance laser-based three-dimensional methane gas cloud imaging telemetry ...
Medical Xpress / A healthy diet may still make a difference for people at higher risk of dementia
Brain changes that can eventually lead to dementia may begin many years before anyone notices symptoms such as memory problems, missed appointments or difficulty finding words.
Science X / Could less caffeine be the smarter performance enhancer? Scientists find a surprising sweet spot
Think of an athlete eyeing the finish line—could a single shot of caffeine be the difference between a podium finish and a personal best? For decades, runners and cyclists have treated the stimulant as a near-magical performance ...
Phys.org / Horizon edge states gain finite description in string theory calculation
Modern physics theories highlight the key role of horizons—boundaries beyond which information cannot reach an observer—in a variety of cosmological and gravitational phenomena. Two renowned examples of these boundaries are ...
Phys.org / Uranus, Neptune may be magma worlds, not ice giants
Uranus and Neptune remain two of the most mysterious objects in the solar system, primarily because they have been visited only by NASA's Voyager 2 spacecraft in 1986 and 1989, respectively. Their "ice giant" moniker comes ...
Phys.org / Ultra-fast light-shaping technology could be 'game-changer' for future imaging
Scientists have developed a new type of "virtual" metasurface—capable of controlling light in ways traditional lenses and optics can't—which they say is superior to the current approach, which relies on ultrathin engineered ...
Medical Xpress / Multiple sclerosis impacts daily life far beyond its physical symptoms, new study finds
Multiple sclerosis (MS) can have a substantial impact on many aspects of life beyond physical health, with 51% of people reporting that the disease affects their social life and 48% reporting that it affects their work, according ...
Tech Xplore / Shifting data center power to off-peak hours could cut grid costs in the age of AI
The number of U.S. data centers is growing, largely to power artificial intelligence programs. That has led to concern about the environmental consequences of data centers—and their impact on the energy grid itself. What ...
Phys.org / Screen reveals new proteins that control RNA processing
Researchers at the University of California San Diego have developed a large-scale screening approach that identifies proteins controlling a fundamental step in gene expression known as alternative polyadenylation (APA). ...
Phys.org / Commute stress can fuel workplace conflict, but research suggests a simple fix
Pothole season, summer construction season or maybe bad weather. No matter the time of year, it's no surprise commuters who drive to work may start their day already feeling a bit on edge.
Phys.org / Do animal behavior experiments give a distorted view of cooperation?
When biologists study cooperation in animals, they usually offer just a single task at a time. But what happens when animals can choose among several opportunities to work together? Biologists at Utrecht University discovered ...
Phys.org / Ancient stellar flyby may still be steering long-period comets today
The Gaia mission has allowed researchers to understand the motions of stars like never before, even revealing possible interactions between our solar system and nearby stars. Planetary Science Institute Senior Scientist Nathan ...
