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.

Scientists identified mutations in a single gene that impair immunity to viruses in a region of the brain called the brain stem.

Günter Blobel, a Nobel Prize-winning Rockefeller biologist who discovered the mechanisms by which proteins are targeted for delivery to specific locations within cells, died February 18 at 81.

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.

A new treatment may help cancer patients who don't respond to traditional immunotherapy. Findings from the first-ever clinical trial reveal that it is effective in activating immune cells that kill cancer cells.

New research shows that subtle differences between bacterial strains may cause dramatic differences in outcome between people infected with the same microbe.

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.

A new study sheds light on how the body fights back against HIV by mutating the viral DNA.

Scientists have engineered a mouse model to study a rare and often-fatal form of liver cancer. They’ve used it to clarify what drives these tumors at the molecular level, and discover new drug concepts.
