Phys.org / Scientists develop method to deliver sugars directly into cells

Sugars, or glycans, play a crucial role in biology—from cell signaling and recognition to interactions with pathogens. Changes in glycosylation are also associated with diseases including cancer. But studying glycans poses ...

Phys.org / Rapid warming may tip Atlantic circulation at 2°C, while slower warming may avert collapse

For several years, climate scientists have shown that the Atlantic Meridional Overturning Circulation (AMOC) could come to a halt if the world warms too much. New research from Utrecht University shows that this picture is ...

Medical Xpress / A few minutes of sprinting could make a bigger impact than 90 minutes of moderate running

Three minutes of sprinting can do something that 90 minutes of moderate exercise apparently cannot: dramatically reshape the molecular contents of the bloodstream. Rockefeller researchers comparing different intensities of ...

Phys.org / Famous oddball quasar isn't X-ray weak after all, astronomers say

For more than two decades, the quasar PHL 1811 has been considered the prototype of a rare class of "intrinsically X-ray weak" quasars, thought to produce unusually little X-ray radiation. But in 2024, the Einstein Probe ...

Tech Xplore / Light-emitting textile sensors could optimize prosthetic fit and comfort

Prosthetics are a fact of life today. It's estimated that more than 50 million people globally—some 2 million of them in the United States—have lost a limb, and most could benefit or already do benefit from artificial limbs ...

Phys.org / Melting diamond could unlock triple fusion gain and the secrets of ice giant planets

Diamond is more than a dazzling gem—the extremely hard form of carbon makes up the pellet that encases fuel for inertial confinement fusion, and scientists believe it rains down deep inside ice giant planets like Neptune ...

Phys.org / Arctic balloon samples trace marine sugars from the ocean to cloud-forming heights

Salt and sugar from the sea can rise as far as the free troposphere, thereby influencing both cloud formation and the Arctic climate. This is the finding of balloon measurements carried out by a team of researchers on Spitsbergen ...

Phys.org / Nature's original bioplastic may have fed animals for hundreds of millions of years

Long before humans discovered biodegradable plastics, microorganisms had already invented their own. Many bacteria and archaea produce natural bioplastics called polyhydroxyalkanoates (PHAs), storing them inside their cells ...

Medical Xpress / Revived rhenium isotope generators answer call for prostate cancer research and other therapies

Haswitha Sabbineni has an idea that could lead to a targeted treatment for prostate cancer. To obtain the rare isotope she needed to test the treatment, she turned to the Department of Energy's (DOE) Oak Ridge National Laboratory ...

Phys.org / Why climate-driven droughts and floods rarely become international news

Three factors—spectacular images, a high death toll and strong personal ties—make it more likely that the media in one country will report on a natural disaster in another, according to a study by the University of Bonn, ...

Phys.org / Hurricane Hunter data reveal early signs of strengthening tropical cyclones

Before tropical cyclones can significantly strengthen, they generally must first become vertically aligned, with their rotating centers stacked through the atmosphere. New research using nearly three decades of NOAA Hurricane ...

Medical Xpress / Coffee consumption linked to leaner body composition and sex-specific hormone patterns

Coffee is one of the world's most widely consumed beverages, and previous research has linked its consumption to a lower risk of conditions such as type 2 diabetes and cardiovascular disease. However, the biological mechanisms ...
