Super-resolution microscopes have revealed a whole new type of connection between neurons in mouse and human brains. In the lab, Johns Hopkins University neuroscientist Minhyeok Chang and colleagues identified tiny tubular bridges in the branching tips of cultured neurons. In further tests on mouse models of Alzheimer’s disease, it appeared the bridges were shuttling calcium and disease-related molecules directly between …

The Arctic Ocean was once an important source of greenhouse gases to the atmosphere — and it could become one again, researchers warn. Methane (CH4) is second only to carbon dioxide (CO2) in trapping heat in Earth’s atmosphere. Since 2020, human-driven greenhouse gas emissions have increased atmospheric methane by about 10 parts per billion per year, more than twice as …

The first-ever detection of heavy water in a planet-forming disk around a young star offers evidence that the water predates the star itself — and it appears this substance even originated in the cold, dark molecular cloud that gave birth to the star. Scientists spotted the heavy water (which we’ll get into in just a moment) in the planet-forming disk …

A newly discovered space rock will zoom safely by Earth later today (Oct. 15) at only about a quarter of the average distance to the moon. The asteroid, called 2025 TP5, will sail by our planet at 4:09 p.m. EDT (2009 UTC) at a minimum distance of 60,328 miles (97,089 km), according to data from NASA’s Jet Propulsion Laboratory. (NASA …

A strange new phase of ice has been discovered during experiments with the world’s largest X-ray laser. Meet ice XXI, a bizarre phase that forms at room temperature, under extreme pressure. The solidified water we’re most familiar with here on Earth is technically known as ice I, but it’s just the tip of the iceberg – for instance, aliens on …

Citizen scientists have found several new “odd radio circles<” or ORCs, in distant, enormous galaxy clusters — and through their discoveries, scientists are learning more about how these huge ring-like structures form. ORCs were first identified only six years ago, in 2019, by Anna Kapinska of the National Radio Astronomy Observatory while perusing observations made by the Australian Square Kilometre …

Summary: Researchers have identified a rare type of brain cell that may drive the chronic inflammation and neurodegeneration seen in progressive multiple sclerosis (MS). These cells, called disease-associated radial glia-like (DARG) cells, appear six times more often in patients with progressive MS than in healthy individuals. DARGs revert to an early developmental state yet also show premature aging, releasing inflammatory …
