Phys.org / Satellites show Earth lost more than 12 trillion tons of ice from Greenland, Antarctica in 47 years
About 12.5 trillion tons (11.3 trillion metric tons) of ice from glaciers in Greenland and Antarctica have melted since 1979, which is enough frozen water to stack ice 5 feet (1.5 meters) deep across the continental United ...
Medical Xpress / Personalized programs to prevent falls may make no difference
Personalized programs designed to reduce falls in older people may make no difference to how often people fall, according to the most comprehensive research review to date.
Phys.org / Virtual cells built from 4D AI models and 'digital twins' could speed up drug discovery
Mitochondria—tiny structures that convert nutrients into energy—are often depicted as discrete kidney bean-shaped objects. But in reality, they form a dynamic, interconnected network throughout the entire cell, rapidly splitting ...
Medical Xpress / Use of MRI before prostate biopsies increases sharply across U.S. hospitals
Using prostate MRI before a biopsy is a real advance in prostate cancer diagnosis. Multiple randomized trials have shown that imaging the prostate first and then targeting suspicious lesions finds more of the aggressive cancers ...
Medical Xpress / Mifepristone more effective than other common emergency contraception methods
Emergency contraception containing mifepristone prevents more pregnancies with fewer side effects than some other common emergency contraceptive pills, such as levonorgestrel, according to a new review involving 87 trials.
Phys.org / Cooling liquids reveal self-limiting particle clusters behind glass transition
Before diving into the mystery of glass, theoretical physicist Corentin Laudicina takes us back to high school physics for a moment. Although he has spent years studying exactly what happens in a material during the glass ...
Phys.org / To understand the solar cycle, notice how the sun sleeps
The sun is such a constant in our lives that it can be difficult to imagine our star ever changing. But the sun can be quite variable. There are times when its magnetic field is turbulent and generates many sunspots and other ...
Phys.org / How firelight may have shaped the origins of spoken language
When asked about the greatest innovation of humans, people often say language or fire. A new paper suggests these innovations may be more interlinked than we previously assumed.
Medical Xpress / Salivary cortisol patterns linked to cognitive decline over 11 years
In a study published in the journal JAMA Network Open, an irregular pattern and consistently higher levels of the stress hormone cortisol in saliva were associated with cognitive decline later in life. Black participants ...
Medical Xpress / Activated donor immune cells may prevent severe complication after allogeneic stem cell transplantation
Researchers have successfully conducted the first clinical trial using activated regulatory T cells (ATregs, Actileucel)—derived from white blood cells of healthy blood donors. This novel cell therapy aims to prevent graft-versus-host ...
Phys.org / Magma influx explains short-lived bulge at Tanzania's Ol Doinyo Lengai volcano
In 2024, D. Sarah Stamps' team detected and tracked a short-lived bulge in the land around a volcano in Tanzania. In a paper published Sep. 18, Stamps identified the cause of the uplift: 1 million cubic meters of magma pouring ...
Phys.org / The story of Little Italy's Feast of San Gennaro is the story of how Italian immigrants became American
For two weeks in September, everyone wants to be Italian—at least judging by the crowds at the annual Feast of San Gennaro in New York City's Little Italy.
