A buildup of a structural protein called F-actin inside aging brain cells appears to cripple the cellular waste-clearing machinery that keeps neurons healthy, according to a study in Drosophila fruit ...

The Trade-off Between Physiological Authenticity and Experimental Convenience: Navigating the Cellular Foundation of ...

Scientists reveal how sleep protects brain cells, manages metabolic damage, and may help explain links to Alzheimer’s disease.

Past studies in animals have shown that a highly processed diet is linked to memory problems and inflammation in the aged ...

A new study shows that a lack of dietary fiber leads to rapid inflammation in the aging brain's amygdala, impairing emotional memory.

When HHMI Investigator Amita Sehgal started studying sleep 25 years ago, the topic elicited a yawn from most biologists. "In ...

The brain’s ability to do everything from forming memories to coordinating movement relies on its cells producing the right proteins at the right time. But directly measuring this protein production, ...

Tiny amounts of signaling molecules hang around on macrophages to pump up responses to repeated threats, offering a target to treat autoimmune conditions.

Memories are thought to be stored in sparse groups of neurons called engrams. These are the cells that switch on during learning and can later switch on again during recall. In physiological aging and ...

CEVA posted "the highest quarterly revenue in CEVA's history" at $31.3 million for Q4 2025. Non-GAAP net income and diluted income per share for the quarter were $4.9 million and $0.18, compared to $2 ...

Aging doesn’t have to mean losing your past. Scientists have found a way to "reprogram" specific memory-holding neurons, restoring youthful learning and recall in mice.
