Asteroid that wiped out dinosaurs had limited impact on sharks and rays, study shows
A new study using advanced artificial intelligence (AI) has revealed that the asteroid strike that wiped out the dinosaurs 66 million years ago caused only a modest decline in shark and ray species. The findings, published in the journal Current…

Cryoelectron tomography reveals paracrystalline architecture of proteasome storage granules
Cells organize their molecules into distinct functional areas. While textbooks usually refer to membrane-bound organelles such as mitochondria and cell nuclei, recent studies have also revealed organelles without membranes. These include stress…

Caterpillars hear through tiny body hairs, which could inspire improved microphones
No ears, no problem. The tobacco hornworm caterpillar, a common garden pest, can actually detect airborne sound via microscopic hairs on its body, according to a team of faculty and graduate students at Binghamton University. The research could…

Essential oils may provide a natural remedy for antibiotic resistance
Thyme, rosemary, and lavender have long been associated with natural medicine. Today, however, these aromatic plants are increasingly being studied by researchers. “In an era of ever-increasing microbial resistance to antibiotics, there is a…

Overlooked threat: Dams trigger temperature-driven disease in iconic salmonid fish
A new study published in Communications Biology reveals a critical, yet previously overlooked, environmental consequence of man-made dams constructed across rivers and streams. By investigating a key indicator species of ecosystem health, the…

Tropical feedback loop: Butterfly mimicry patterns evolve faster near the equator
In the early 1990s, Keith Willmott and a friend, both undergraduate students from the United Kingdom, arrived in Ecuador with impressionable minds and big aspirations. Willmott initially imagined there might be 20 to 30 butterfly species in the…

A sea turtle with 3 flippers swims free after Florida rehab, now followed by satellite
Cheers rose from a bundled-up crowd as a loggerhead sea turtle that survived a likely shark attack trundled back into the ocean after months of rehabilitation in Florida, carrying a satellite tracker to see how she fares with only three flippers.

Plant mothers send molecular 'text messages' to pollen
Small RNAs are short RNA molecules that help determine which genes in a cell are switched on or off. Until now, it was assumed that the small RNAs necessary for pollen development originate in the pollen itself and in the directly surrounding…

Changing land use can increase threat of animal‑to‑human disease spread
Changes to land use can directly heighten the risk of diseases spreading from animals to humans, new University of Stirling–led research has shown. The study, led by Dr. Adam Fell of the University’s Faculty of Natural Sciences, shows that…
