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 / 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 ...
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 ...
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 ...
Medical Xpress / Common bacteria discovered in the eye linked to cognitive decline
Chlamydia pneumoniae—a common bacterium that causes pneumonia and sinus infections—can linger in the eye and brain for years and may aggravate Alzheimer's disease, according to a study from Cedars-Sinai. Published in ...
Medical Xpress / Premature aging may result from immune responses triggered by faulty DNA repair
DNA is often described as the instruction manual for building the fundamental components of life. Proteins are helpers that aid DNA in carrying out essential processes such as replication, repair, and transcription. Under ...
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 / Strategic tree planting could help Canada become carbon neutral by mid-century
A new study finds that Canada could remove at least five times its annual carbon emissions with strategic planting of more than six million trees along the northern edge of the boreal forest. The paper, "Substantial carbon ...
Phys.org / New 3D map of the sun's magnetic interior could improve predictions of disruptive solar flares
For the first time, scientists have used satellite data to create a 3D map of the sun's interior magnetic field, the fundamental driver of solar activity. The research, published in The Astrophysical Journal Letters, should ...
Phys.org / Supermassive black holes sit in 'eye of their own storms,' studies find
Gigantic black holes lurk at the center of virtually every galaxy, including ours, but we've lacked a precise picture of what impact they have on their surroundings. However, a University of Chicago-led group of scientists ...
