Scientists exploring the brain’s “blue place” discovered the longest neuron ever measured in a mouse and uncovered new clues about how the brain learns. When mice in a decision-making experiment switched their choices after a negative outcome, neurons near the top of a tiny brainstem region became active. Just before the mice ignored cues that […]
Scientists Discover a New Cousin of Diamond That Was Thought To Exist Only in Theory
Diamond and graphite have a new carbon cousin called diamondiyne, with a crystal structure confirmed so far only in microscopic patches. A carbon structure proposed 35 years ago has finally taken shape in a thin film where two liquids meet. Using relatively inexpensive equipment, researchers at the University of Gothenburg have created diamondiyne for the […]
A Missing Molecule May Explain Why Muscles Weaken With Age
Restoring just part of a depleted mitochondrial fat began reversing muscle wasting in mice, suggesting a possible route toward treating age-related muscle decline. As muscles weaken with age, they shift toward fibers built for endurance rather than quick, powerful bursts of movement. These slow-twitch fibers contain more mitochondria, the structures that supply cells with energy, […]
Antibiotic Resistance Is Making This Dangerous Gut Bacterium Even Harder To Kill
An antibiotic resistance gene helps a dangerous gut bacterium build tougher spores that can survive hospital disinfectants. A hospital surface can be disinfected and still harbor dormant spores of Clostridioides difficile, a bacterium that causes diarrhea that can be deadly for already sick patients. Researchers have now found that an antibiotic resistance gene can help […]

Scientists Discover a Hidden Trigger That Keeps Inflammation Alive
Inflammation persists after proteins detach from immune receptors, revealing a potential target for autoimmune treatments. Since a Nobel Prize-winning discovery in the 1990s identified molecules called Toll-like Receptors as the guardians of the human immune system, researchers have pursued a straightforward strategy for treating autoimmune diseases. By developing therapies that interfere with these receptors, scientists […]
Scientists Unlock 700,000-Year-Old Secrets Hidden Inside a Giant Elephant Tooth
A giant elephant’s tooth has preserved clues to the watery world that sustained early humans nearly 700,000 years ago. Researchers studying elephant remains from Gesher Benot Ya’aqov (GBY-NBA) in northern Israel have reconstructed a Pleistocene environment rich in water, vegetation, and wildlife. Published in Quaternary Science Reviews, the study reveals the landscape shared by enormous […]
