1+ hour, 41+ min ago   (726+ words) Researchers at Carnegie Mellon University's School of Computer Science, the University of Pittsburgh School of Medicine and the University of Washington have uncovered a previously underexplored feature of Alzheimer's disease that may help scientists identify new avenues for treatment. To…...

2+ hour, 22+ min ago   (262+ words) A massive worldwide survey of physicists has revealed surprisingly little agreement about some of the universe’s biggest mysteries. No majority backed the standard cosmological model, a leading explanation for dark matter, or any single theory of quantum gravity. One area…...

3+ hour, 20+ min ago   (460+ words) The Indian and Pacific oceans have been climatically linked for centuries, but scientists say that connection is now breaking down in an exceptional way. Ancient climate records suggest volcanoes disrupted the relationship in the past, while today human-caused warming appears…...

3+ hour, 34+ min ago   (669+ words) Electron microscopes can reveal structures far smaller than anything visible with ordinary light. But researchers in Austria say conventional electron microscopes may be leaving valuable information on the table. In a standard system, electrons are mainly counted to build an…...

3+ hour, 43+ min ago   (569+ words) Scientists have engineered yeast to turn PET plastic and agricultural waste into ingredients for protein-rich, 3D-printed cookies called µBites. Developed partly for NASA’s Deep Space Food Challenge, the system can produce proteins, fats, vitamins, and even vanilla flavoring from waste…...

4+ hour, 16+ min ago   (255+ words) Researchers have experimentally demonstrated the optical Magnus effect for the first time, revealing that a tightly focused laser interacts most strongly with an atom slightly away from the beam’s center. The unexpected shift is similar to the physics that makes…...

1+ day, 1+ hour ago   (568+ words) Cause and effect. We understand this concept from an early age. Tug on a pull toy's string, and the toy follows. Naturally, things get much more complicated as a system grows, as the number of variables increases, and as noise…...

11+ hour, 54+ min ago   (953+ words) Venus looks pale yellow in ordinary visible light, but the view changes dramatically in ultraviolet wavelengths. There, dark and bright features sweep across the planet's upper sulfuric acid clouds. Scientists have observed these patterns for about a century, yet the…...

12+ hour, 23+ min ago   (361+ words) Ancient rocks from Western Australia suggest water was reaching deep inside Earth more than three billion years ago, long before modern plate tectonics may have fully developed. Researchers propose that water-rich pieces of crust periodically sank into the mantle through…...

13+ hour, 54+ min ago   (659+ words) Scientists have uncovered a natural braking system that helps the immune system switch off inflammation and prevent harmful immune cells from building up. Boosting this pathway in people reduced inflammation-related immune changes and sped up pain relief, pointing toward potential…...
