Every day, millions of people with bipolar disorder take medicines to stabilize their moods. But just how these drugs work is still a mystery. Now, a new study of brain tissue helps reveal what might actually be happening. And further research using stem cells programmed to act like brain cells is already underway.
The irony of getting away to a remote place is you usually have to fight traffic to get there. After hours of dodging dangerous drivers, you finally arrive at that quiet mountain retreat, stare at the gentle waters of a pristine lake, and congratulate your tired self on having "turned off your brain."
For scientists working to uncover the mysteries of the brain, fat is a problem. The fats inside cells bend and scatter light, obscuring researchers’ views when they try to peer deep into tissue. A new technique developed by HHMI scientists solves that problem by removing the fat from the brain and supporting the remaining brain structures in a hydrogel—literally giving scientists a clear view of an intact brain. The technique, called CLARITY, transforms biological tissue into an optically transparent sample that retains its original structure and molecular information.
Deep inside your brain, a legion of stem cells lies ready to turn into new brain and nerve cells when you need them. New research shows the vital role of a type of internal “spring cleaning” that both clears out garbage inside the cells, and keeps them in their perpetual stem-cell state.
University of Utah researchers developed a high-speed camera system that spent the past two winters photographing snowflakes in 3-D as they fell – and they don’t look much like those perfect-but-rare snowflakes often seen in photos.
