In brief: Tweaking RNA protects cells from harmful inflammation

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.

Günter Blobel, a Nobel laureate who redefined cell biology, has died

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.

In brief: New molecular insights on a rare immune disorder

After figuring out the functions of two proteins involved in the rare genetic condition ICF, scientists pieced together the molecular process that is altered in the disease.

In brief: How the immune system curbs its own mistakes

Researchers discovered how apoptosis keeps potential cancer-causing mutations in check.

3D imaging of fat reveals potential targets for new obesity treatments

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.

In brief: New clues about how cells restart stalled replication

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.

Brain research points the way to new treatments for nicotine addiction

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.

Michel C. Nussenzweig wins 2017 Sanofi-Institut Pasteur Award

Nussenzweig was honored at a ceremony today at the Institut Pasteur in Paris.The award recognizes investigators for past or ongoing work demonstrating real scientific progress in the life sciences.

Michael W. Young receives 2017 Nobel Prize in Physiology or Medicine

Young was honored for his discoveries of molecular mechanisms controlling the circadian rhythm. He accepted the Nobel medal and diploma from King Carl XVI Gustaf of Sweden.

Glial cells, not neurons, lead the way in brain assembly

Researchers have found that the cells directing the very first steps of brain formation are not other neurons, as scientists have long assumed. They've also uncovered previously hidden molecular pathways that attract neurons into the brain.
