Dec 2nd 2024, 12:39

Biology textbooks may need a revision, say scientists, who present new evidence that an arm-like structure of mammalian brain cells may be a different shape than scientists have assumed for more than a century.

Dec 2nd 2024, 12:36

A cancer therapy that prompts the body's immune defenses against viruses and bacteria to attack tumors can make patients more vulnerable to heart attack and stroke. A possible explanation for this side effect is that the treatment interferes with immune regulation in the heart's largest blood vessels, a new study suggests.

Dec 2nd 2024, 12:35

Scientists have invented a liquid ink that doctors can print onto a patient's scalp to measure brain activity. The technology offers a promising alternative to the cumbersome process currently used for monitoring brainwaves and diagnosing neurological conditions. It also has the potential to enhance non-invasive brain-computer interface applications.

Dec 2nd 2024, 12:35

Ketone bodies are not just about energy. These metabolites are powerful signaling molecules that have profound effects on the proteome and protein quality control in the brain. Scientists, working in mouse models of Alzheimer's disease and aging, and in the nematode C. elegans, reveal the ketone body -hydroxybutyrate interacts directly with misfolded proteins, altering their solubility and structure so they can be cleared from the brain through the process of autophagy. The work hints at a tantalizing possibility -- ketone bodies as a global treatment to restore the integrity of the proteome, addressing one of the key hallmarks of aging.
