Enhanced environment restores memory in mice with neurodegeneration

... have been known for half a century, nobody really knows the mechanism behind it," said Tsai. "However, there has also been a growing body of evidence that chromatin remodeling has a beneficial effect on learning and memory," she said. Chromatin is found in the nuclei of cells. It is composed of DNA spool...

Study links faulty DNA repair to Huntington's disease onset

...gtons disease is a progressive disease, but nobody knows exactly why," said McMurray. "Our work supports the idea that the disease progresses when the extra segment expands over time in non-dividing cells such as nerve cells." McMurrays study shows that the inserted segment grows when cells try to remove...

The cost of long tongues

...ally do impose a mechanical cost on bees. Everyone knows just how busy bees can be, but orchid bees are basically sacrificing speed at flowers for exclusive access to them. Borrell thinks this may be because the rewards at these flowers can be tremendous, up to ten times the quanity of nectar provided by t...

Rush principal investigator cardiologist Dr. Gary Schaer, head of the Rush Cardiac Catheterization Laboratory, says one reason the study results are so promising is that these stem cell...

UGA research shows rats are capable of reflecting on mental processes

.... Its the first demonstration that any non-primate knows when it doesnt know something, and it could open the way to more in-depth studies about how animalsand humansthink. "This kind of research may change how we think about cognition and memory in animals," said Jonathon Crystal, an associate professor...

Looking for life on Jupiter's icy moon Europa

..., a member of the campus's Museum of Paleontology, knows the bizarre places organisms can thrive, and the unique processes that can bring life from deep under the ice to the surface. This is relevant because Europa, the third largest of Jupiter's moons, is thought to have a thick ocean of water overlain by...

Robotic cameras join search for 'Holy Grail of bird-watching'

...ons for placing the remote cameras. Because no one knows exactly where the bird might appear, the cameras must cover a relatively wide swath of sky. They settled upon a power line that cuts through the bayou and provides a 50-foot-wide clearing unobstructed by trees. "It's a natural bottleneck in the f...

HIV protein enlisted to help kill cancer cells

Hawkins, M.D., assistant professor of surgery and a member of the Siteman Cancer Center at the School of Medicine and Barnes-Jewish Hospital. "A portion of the HI...

'Electric' fish shed light on ways the brain directs movement

...the same way that a driver approaching a red light knows he has to apply the brakes ahead of time to avoid overshooting and ending up in the middle of a busy intersection," Fortune said. "Your brain has to do this all the time when controlling movement because your body and limbs, like a car, have mass. Th...

How does your brain tell time?

...rains ability to accurately tell time. Yet no one knows how the brain does it." The most popular theory assumes that a clock-like mechanism which generates and counts regular fixed movements -- underlies timing in the brain. In contrast, Buonomano suggests a physical model that operates without usin...

McBride shows DNA detective work with paper-eating bacteria that 'glide'

...go, his lab had found one protein involved. He now knows of 24, and he doesn't expect to find many more. Until recently, McBride was not able to image the bacteria closely enough to see the structures involved in movement. Instead, he bonded latex spheres to the surface of F. johnsoniae cells and observed...

Unfolded proteins may protect cells from dying

...young skin and is also prone to ulceration. No-one knows why skin atrophy occurs, but it is becoming more common as people live longer, and there is no effective treatment for it. One characteristic of atrophic skin is that, compared to normal skin, it contains less hyaluronatea large carbohydrate componen...

The traditional view is that DNA is relatively rigid and that considerable energy is required when it needs to be bent to form protein-DNA comp...

Mysterious 'neural noise' actually primes brain for peak performance
