A new computational approach reveals how subtle structural changes in polyheptazine imides can dramatically influence their ability to convert sunlight into chemical energy. Photocatalysis offers a promising way to convert abundant sunlight into useful chemical energy. Among the materials attracting attention for this purpose are polyheptazine imides, which possess distinctive structural and functional features that […]
Scientists Spin Molecules Inside a Frictionless Superfluid for the First Time
A newly designed optical centrifuge allows scientists to control molecular rotation inside superfluid helium nano-droplets. Physicists have developed a new version of an optical centrifuge that can control how molecules rotate while they are suspended inside liquid helium nano-droplets. The advance brings scientists closer to understanding the unusual properties of superfluids, a rare state of […]
Scientists Discover Molecular “Switch” That Could Stop Breast Cancer From Spreading
A receptor involved in normal physiological processes may also drive breast cancer growth when overexpressed. A surgeon can remove a breast tumor, but surgery does not always eliminate every cancer cell. This is particularly true when the disease has already spread beyond its original location in the body. Scientists are still uncovering the molecular processes […]

Asteroid Impacts Could Launch Living Microbes From Mars
A super-tough microbe may be able to survive being blasted from Mars into space—opening the door to interplanetary life transfer. A remarkably tough bacterium known as Deinococcus radiodurans may be able to endure the intense forces created when an asteroid slams into Mars and blasts material into space. The battered surfaces of the Moon and […]

Common Arthritis Drug Found To Lower Blood Pressure and Boost Heart Health
A widely used treatment for rheumatoid arthritis may offer an unexpected cardiovascular benefit. Methotrexate has been a staple treatment for rheumatoid arthritis for decades, valued for its ability to calm an overactive immune system and reduce painful joint inflammation. Now, researchers say it may deliver an unexpected bonus that matters far beyond the joints: lower […]
Even Mild COVID-19 Can Leave Lasting Brain Damage, Study Finds
A new study suggests that recovery from COVID-19 may not end when respiratory symptoms fade. A mild bout of COVID-19 or influenza may have effects that continue long after obvious symptoms such as fever and coughing disappear. New research from Tulane University suggests these hidden changes could help explain why some people do not feel […]
Scientists Drill 523 Meters Through Antarctic Ice, Uncovering 23 Million Years of Climate Secrets
Deep beneath Antarctica’s ice, scientists have uncovered a geological archive that could reshape predictions of future sea-level rise. Working roughly 700 kilometers from the closest Antarctic research stations, the team drilled through 523 meters of solid ice at Crary Ice Rise, located along the edge of the West Antarctic Ice Sheet. Beneath the ice, they […]
