Phys.org / Gravitational wave signal tests Einstein's theory of general relativity
For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers an opportunity to test ...
Phys.org / Open-access software tool helps researchers spot fake journals
Research papers in peer-reviewed academic journals are at the heart of academic integrity. New ideas and discoveries are vetted and checked by experts in the field as the boundaries of scientific knowledge are pushed forward. ...
Phys.org / Farm waste could lock away carbon for decades
Agricultural waste that is usually burned or left to rot could play a far bigger role in tackling climate change if it were instead used in long-lasting building materials, according to new research from the University of ...
Phys.org / JWST discovers a new extremely metal-poor dwarf galaxy
Using the James Webb Space Telescope (JWST), astronomers have discovered a new dwarf galaxy, which received designation CAPERS-39810. Further investigation of CAPERS-39810 revealed that it is an extremely metal-poor galaxy. ...
Phys.org / Global warming is speeding breakdown of major greenhouse gas, research shows
Scientists at the University of California, Irvine have discovered that climate change is causing nitrous oxide, a potent greenhouse gas and ozone-depleting substance, to break down in the atmosphere more quickly than previously ...
Phys.org / New model predicts the melting of free-floating ice in calm water
A pair of US researchers have developed a new model to tackle a deceptively simple problem: how a small block of ice melts while floating in calm water. Using an advanced experimental setup, Daisuke Noto and Hugo Ulloa at ...
Phys.org / A new method to search for ultralight dark matter with advanced optical cavities
Dark matter is a mysterious type of matter that does not emit, absorb, or reflect light, yet is predicted to account for most of the universe's mass. While physicists have gathered extensive indirect evidence of its existence, ...
Phys.org / Signs of Sir Terry Pratchett's dementia may have been hidden in his books
Signs of Sir Terry Pratchett's dementia may have been present in his writing a decade before his official diagnosis, new research has found. Researchers have examined the lexical diversity—a measure of how varied an author's ...
Medical Xpress / GLP-1 drugs tied to lower-calorie, lower-sugar food purchases
Researchers at Steno Diabetes Center Copenhagen reported that starting a GLP-1 receptor agonist (GLP-1RA) coincided with slightly healthier supermarket purchases. Grocery purchases from GLP-1RA users in Denmark contained ...
Phys.org / Land-intensive carbon removal requires better siting to protect biodiversity, study warns
New research looks at carbon dioxide removal—where carbon is absorbed from the atmosphere and stored—and finds that large-scale reliance on land-based methods, such as planting forests or bioenergy with carbon capture ...
Phys.org / Weight-loss drugs are creating an environmental disaster—a new water-based method aims to change that
The world is in the middle of a peptide drug revolution. These short chains of amino acids—the building blocks of proteins—sit at the heart of some of the most successful medicines ever created, from weight-loss injections ...
Phys.org / Hypothermia risks increase in Mississippi and Tennessee with next wave of frigid temperatures
With another wave of dangerous cold heading for the U.S. South on Friday, experts say the risk of hypothermia heightens for people in parts of Mississippi and Tennessee who are entering their sixth day trapped at home without ...
