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.
In brief: A close look at how HIV-fighting proteins slow the virus down
A new study sheds light on how the body fights back against HIV by mutating the viral DNA.
New study points the way to therapy for rare cancer that targets the young
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.
In the fight against viral infection, spelling counts
Scientists have discovered a peculiarity in the genetic code of HIV that might explain how this and other viruses evolved ways to dodge our immune system. The findings could make it possible to develop safer vaccines.
Targeting a single protein might treat a broad range of viruses
Scientists have identified a protein that many viruses require to spread within a host—a discovery that could lead to fighting diseases as varied as parainfluenza, West Nile, and Zika with a single drug. This finding could also lead to the development of treatments for emerging viruses.
