Crushed shells helped young clams grow larger shells in laboratory tests, showing how a long-standing Indigenous coastal practice can offer local protection against ocean acidification. For a young clam, the surrounding water can threaten the shell it is trying to grow. When seawater absorbs excess carbon dioxide from the atmosphere, it becomes more acidic, making […]
Earthquake Faults Can Suddenly Become Almost As Fluid as Water, Study Finds
Scientists have uncovered evidence of an unexpected process that may allow earthquake faults to slip enormous distances. Rocks along Japan’s Boso Peninsula have preserved evidence of an extraordinary process that may occur during powerful earthquakes. Researchers discovered ancient fault structures suggesting that clay trapped between moving rock surfaces became nearly as fluid as water, potentially […]
Scientists Reveal How a Mysterious Brain Structure Keeps Memories From Fading
Memories that last only seconds shape everyday thinking, and research in mice is revealing how a small brain structure supports an ability impaired in ADHD and schizophrenia. To understand a sentence, the brain has to keep earlier words in mind as new ones arrive. Working memory makes that possible, holding information for a few seconds […]

The Hidden Brain Mechanism That Makes You Love Coffee, Chocolate, Fat, and Sugar
Scientists have uncovered a previously understudied dopamine pathway that may explain how we learn to enjoy flavors we initially dislike. A food can become more appealing even when its flavor stays exactly the same. Researchers at UC San Francisco have identified a previously understudied dopamine pathway that helps the brain learn which flavors are worth […]
A New Era of Bionic Vision? AI Helps Scientists Unlock the Brain’s Visual Cortex
Researchers have used artificial intelligence to improve how a brain implant stimulates the visual cortex of a blind person, potentially advancing the development of bionic eyes. Artificial intelligence could make future bionic eyes more precise and responsive by improving how electrical signals communicate with the brain. In a study published in Neuron, researchers used deep […]
Scientists Spent 7 Years Studying Moth Wings and Discovered Something Unexpected
A search to change the patterns on moth wings uncovered something unexpected: wider tails, suggesting that evolution may reshape insects’ defenses by modifying features they already possess. A luna moth’s leaf-like wings help it escape the notice of predators that hunt by sight. Other giant silk moths display prominent eyespots that can make them look […]
Scientists Discover Crows Make Decisions Twice As Fast as Humans
Quick decisions are essential for birds navigating the world at high speed, and new research suggests crows may have a remarkable advantage over humans in processing what they see. A crow can make a visual decision in less than a quarter of a second, about twice as fast as a human or monkey. Researchers at […]
A Tiny, Jelly-Like Implant Could Change How We Treat High Blood Pressure
A soft implant that attaches without stitches lowered blood pressure in rats, pointing toward a way to treat hypertension with less damage to surrounding tissue. Nearly half of all adults in the United States have high blood pressure, a leading cause of heart disease. Medications and changes to diet or lifestyle can help, but roughly […]
