Scientists have outlined a molecular program by which serotonin reuptake inhibitors reshape the brain to alleviate depression. Their findings provide clues for how to make better and faster-acting versions of these drugs.
Scientists have found that a hormone tells the brain to dramatically restructure neurons embedded in fat tissue. Their work widens our understanding of how the body regulates its energy consumption, and how obesity might be treated in the future.
How do primitive cells “know” where to go during development? Scientists studying the fish equivalent of inner-ear hair cells have shown that biochemical and mechanical cues work together to orchestrate a highly complex arrangement.
Researchers have identified a set of biological factors in mice that seem to determine one's ability to bounce back from a traumatic event, and provide preliminary evidence that a naturally-occurring substance may help boost resiliency in the face of stressful situations.
Protein clumps are routinely found in the brains of patients with neurodegenerative diseases. Now researchers find a link between this buildup and the intracellular movement of proteasomes, molecular machines tasked with degrading protein waste inside cells.
A new study finds that neurons affected in Parkinson’s disease can shut down without fully dying, allowing them to also switch off neighboring cells. The findings might give scientists a better understanding of how the condition wreaks havoc in the brain, as well as ideas for new treatments.
