New research has helped explain what goes wrong in Aicardi-Goutières syndrome, a rare brain disorder. Patients with the disease have genetic abnormalities that may put their cells at risk of accidentally triggering an antiviral response.
A new study illuminates the biology that guides behavior across different stages of life in worms, and suggests how variations in specific neuromodulators in the developing nervous system may lead to occasional variations.
Virtually all aspects of life and disease depend of brief exchanges between cells. A new technique to study cell-to-cell contacts lets interacting cells “smear” one another with the biological equivalent of lipstick.
The symptoms of Huntington’s typically appear in middle age, but the disease may in fact originate much earlier. New research shows that a patient’s neural abnormalities may arise already during embryonic development—suggesting that treating the disease early may be beneficial.
With new imaging methods, scientists hope to make significant progress in the fight against obesity. A new report reveals striking images of neural projections within fat tissue, and clues for the development of new drugs.
Scientists studying the cell’s DNA-copying machinery have discovered a molecular mechanism that helps reactivate it should it stop prematurely. Its function may prevent genetic errors like those that cause cancer.
Scientists have discovered a group of brain cells that may play a role in keeping smokers addicted to nicotine. Their work could ultimately lead to new drugs to help people conquer their tobacco dependence.
