The smell of Egyptian mummies is revealing 2,000-year-old secrets
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, beeswax, and bitumen used during embalming. The chemical clues reveal that mummification grew increasingly complex over thousands of years.
A strange twist in the universe’s oldest light may be bigger than we thought
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 background could point to entirely new physics, including hidden particles such as axions and clues about dark matter or dark energy.
Scientists discover what really happens during sourdough fermentation
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 fibres called arabinoxylans. This process may influence the bread’s texture, digestibility, and flavor. Some microbes even create buttery or subtly sweet notes that give sourdough its distinctive taste.
Common pesticide may more than double Parkinson’s disease risk
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 likelihood of developing the disorder. Lab experiments reinforced the finding: animals exposed to the chemical developed movement problems, lost dopamine-producing neurons, and showed the same toxic protein buildup seen in Parkinson’s patients.
Scientists inject one tumor and watch cancer vanish across the body
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 instead of into the bloodstream. In a small clinical trial of 12 patients with metastatic cancers, six saw their tumors shrink and two experienced complete remission.
Life rebounded shockingly fast after the asteroid that killed the dinosaurs
The asteroid impact that wiped out the dinosaurs didn’t keep life down for long. New research shows that microscopic plankton began evolving into new species within just a few thousand years—and possibly in under 2,000 years—after the disaster. Scientists uncovered this rapid rebound by using a rare isotope marker to more accurately measure time in ancient sediments. The discovery suggests life recovered far faster than previously thought.
Scientists just discovered a tiny signal that volcanoes send before they erupt
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 hours before an eruption begins. Tested for more than a decade at the Piton de la Fournaise volcano on La Réunion, the tool successfully predicted 92% of eruptions between 2014 and 2023, sometimes giving up to eight hours of warning.
Cells can sense 10x farther than expected and it may explain cancer spread
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 detect layers as far as 100 microns away. This long-range “depth sensing” helps cells decide where to migrate. Understanding how it works could reveal new targets to stop cancer from spreading.
Astronomers just found the source of the brightest fast radio burst ever
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 other radio source in its galaxy. Follow-up observations with the James Webb Space Telescope spotted a faint infrared signal at the same location. The burst’s unusual behavior—showing no signs of repeating—may challenge current ideas about what causes
Scientists discover hidden water beneath Mars that could have supported life
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 of life. Even after surface water disappeared, subsurface flows may have created protected environments for microbes. These hidden habitats could be key targets in the ongoing search for past life on Mars.
Crops irrigated with wastewater store drugs in their leaves
Scientists studying crops irrigated with treated wastewater discovered that trace pharmaceuticals often collect in plant leaves. Tomatoes, carrots, and lettuce absorbed medications such as antidepressants and seizure drugs during the experiment. However, the edible portions of tomatoes and carrots contained much lower levels than the leaves. The findings help researchers understand how crops process contaminants as wastewater reuse becomes more common.
The financial crisis that quietly stunted a generation
When the Asian financial crisis sent rice prices soaring in Indonesia in the late 1990s, the shock didn’t just strain household budgets—it left lasting marks on children’s bodies. Researchers from the University of Bonn found that kids exposed to the food price surge were more likely to experience stunted growth and, years later, a higher risk of obesity. The findings suggest that during crises, families often maintain calorie intake but cut back on nutrient-rich foods, creating hidden nutrition
