Astronomers may have found an exciting new clue about dark energy--the mysterious force driving the universe's accelerating expansion. They discovered an extraordinarily bright supernova from more than 10 billion years ago whose light was bent and .. ...

Scientists studying a mysterious effect called cosmic birefringence--a subtle twist in the polarization of the universe's oldest light--have developed a new way to reduce uncertainty in how it's measured. This faint rotation in the cosmic microwave . ...

A redesigned cancer immunotherapy is showing striking early results after decades of disappointment with similar drugs. Researchers engineered a more powerful CD40 agonist antibody and changed how it's delivered--injecting it directly into tumors ...

A new UCLA Health study suggests that long-term exposure to the pesticide chlorpyrifos may dramatically raise the risk of Parkinson's disease. Researchers found that people living in areas with sustained exposure had more than 2.5 times the ...

New research shows that sourdough fermentation does more than make bread rise--it transforms wheat fibers in unexpected ways. Scientists found that enzymes already present in wheat, activated by the sourdough's acidic environment, break down key ...

The distinctive smell of ancient mummies is helping scientists decode the secrets of Egyptian mummification. By analyzing tiny traces of chemicals in the air around mummy samples, researchers identified dozens of compounds linked to oils, resins, ...

Scientists have discovered that cells can sense far beyond the surfaces they touch. While individual cancer cells can probe about 10 microns ahead by tugging on surrounding collagen fibers, clusters of normal epithelial cells can combine forces to .. ...

A new detection method called "Jerk" could dramatically improve how scientists forecast volcanic eruptions. By using a single broadband seismometer, the system can detect extremely subtle ground movements caused by magma pushing underground--often .. ...

Astronomers have discovered the brightest fast radio burst ever detected and traced it to a nearby galaxy using a new network of CHIME Outrigger telescopes. The flash, nicknamed RBFLOAT, lasted only a fraction of a second but briefly outshone every . ...

New research suggests Mars may have remained habitable much longer than scientists once thought. Ancient sand dunes in Gale Crater appear to have been soaked by underground water billions of years ago, leaving behind minerals that can preserve signs ...
