Antarctica’s “Doomsday Glacier” could raise sea levels twice as much as predicted

Antarctica’s Thwaites Glacier may be melting twice as much as previously predicted, even without additional global warming. Scientists discovered that warm ocean water is penetrating miles beneath the ice, weakening its foundations and accelerating its retreat. A new model predicts that the glacier could add up to 30 millimeters to global sea levels by 2100, with a 60% chance of losing a crucial stabilizing ridge.

A simple daily fiber supplement reduced arthritis pain and improved strength

A new clinical trial suggests that a simple daily fiber supplement could significantly reduce knee osteoarthritis pain, improve muscle strength, and make the body less sensitive to pain. Researchers discovered that the benefits may be linked to changes in gut bacteria and the hormone GLP-1, revealing a promising new approach to arthritis relief.

The autistic brain processes faces differently than scientists thought

A major new study reveals that autistic children’s brains process faces differently, and those differences may begin earlier than scientists previously thought. Researchers found that brain signals associated with recognizing faces become more specialized as neurotypical children grow older, but show much less change in autistic children. The discovery could help explain why some autistic people have difficulty recognizing faces and reading emotions.

The asteroid that killed the dinosaurs may have helped ants conquer the world

The asteroid that killed the dinosaurs may have set the stage for ants to conquer the planet, with a surprising boost from “jumping genes” hidden in their DNA. Scientists discovered that bursts of activity from these mobile genetic elements coincided with the rise of major ant groups and may have helped sharpen their extraordinary ability to communicate through smell.

Scientists discover the immune system’s hidden sense of touch

Scientists at McGill University have discovered a surprising new ability of immune cells that could change how we understand long-term immunity. Researchers found that T cells can actually sense how stiff their surrounding tissues are, using these physical signals to help determine whether they develop into long-lasting memory cells that protect against future infections.

A new survey of Canadian English shows what has changed in 50 years

Over the past 50 years, Canadian English has become more uniform across regions and has adopted many American terms and pronunciations, while the use of Canadian spellings has gained in popularity. These are the key results of a large-scale study by McGill researchers to update the Survey of Canadian English, initially done in 1972.

How we rewrite memories of fallen artists—but not their art

What happens to our memories when we learn disturbing news about a beloved artist? New research from the University of South Florida finds that after a scandal, the brain tricks us: it reconciles a fallen artist with their adored art by rewriting our memories in two completely different directions.
