Biologists are studying retinal regeneration in zebrafish to find ways to combat human eye diseases. The small, minnow-like fish have eyes that develop in a way very similar to humans, but have the ability to regenerate retinal cells following an injury.
When you're expecting something— like the meal you've ordered at a restaurant— or when or when something captures your interest, unique electrical rhythms called gamma oscillations sweep through your brain. New research shows that little known supportive cells in the brain known as astrocytes may in fact be major players that control these waves.
When a muscles contracts it generates electricity. This electrical activity remains in the muscles of an amputated limb. It has long been a goal to use these natural muscle signals to enhance the control of hand and arm prosthetics. Previously, researchers did this by attaching two external sensors to the surface of the skin of the residual limb. The sensors were connected to a prosthesis controller by wires.
Parents, turn off the television when your children are with you. And when you do let them watch, make sure the programs stimulate their interest in learning. At least, that's the advice arising from researchers who examined the impact of television and parenting on children’s social and emotional development.
On this episode of Bioscience Technology This Week, Editor-in-Chief Rob Fee reports on research claiming that the sense of smell is linked to Alzheimer's Disease development. Our second story examines a new process that could aid cells in gobbling up undesirable neighbors.
Researchers of the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden report how they managed to capture detailed three-dimensional images of cardiac dynamics in zebrafish. The novel approach: They combine high-speed Selective Plane Illumination Microscopy (SPIM) and clever image processing to reconstruct multi-view movie stacks of the beating heart.
The HIV-1 virus has proved to be tenacious, inserting its genome permanently into its victims' DNA, forcing patients to take a lifelong drug regimen to control the virus and prevent a fresh attack. Now, a team of Temple University School of Medicine researchers has designed a way to snip out the integrated HIV-1 genes for good.
Researchers have successfully used a new and potentially safer method to stimulate ovulation in women undergoing IVF treatment. Twelve babies have been born after their mothers were given an injection of the natural hormone kisspeptin to make their eggs mature.
Scientists at the Salk Institute have identified a gene responsible for stopping the movement of cancer from the lungs to other parts of the body, indicating a new way to fight one of the world's deadliest cancers. By identifying the cause of this metastasis—which often happens quickly in lung cancer and results in a bleak survival rate—Salk scientists are able to explain why some tumors are more prone to spreading than others.
Rice University scientists have succeeded in analyzing transmembrane protein folding in the same way they study the proteins’ free-floating, globular cousins. Rice theoretical biologist Peter Wolynes and his team at the university’s Center for Theoretical Biological Physics (CTBP) have applied his energy landscape theory to proteins that are hard to view because they live and work primarily inside cell membranes.
In mice with diet-induced diabetes, the equivalent of type 2 diabetes in humans, a single injection of the protein FGF1 is enough to restore blood sugar levels to a healthy range for more than two days, according to a new study.
On this episode of Bioscience Technology This Week, Editor-in-Chief Rob Fee reports on the finding that some chimpanzees are smarter than others due to genetics. Our second story reports on how the same genes influence reading and math abilities.
As daily temperatures increase, so does the number of patients seeking treatment for kidney stones. In a study that may both reflect and foretell a warming planet’s impact on human health, a research team found a link between hot days and kidney stones in 60,000 patients in several U.S. cities with varying climates.
On this episode of Bioscience Technology This Week, Editor-in-Chief Rob Fee reports on the possible double-punch of tick bites and how to control and undo years of heart damage.
A neuroscience study provides new insight into the primal brain circuits involved in collision avoidance, and perhaps a more general model of how neurons can participate in networks to process information and act on it. In the study, neuroscientists tracked the cell-by-cell progress of neural signals from the eyes through the brains of tadpoles as they saw and reacted to stimuli including an apparently approaching black circle.
