Ever wonder why it’s hard to focus after a bad night’s sleep? Using mice and flashes of light, scientists show that just a few nerve cells in the brain may control the switch between internal thoughts and external distractions.
In this episode of Bioscience Technology This Week, Rob Fee discusses how studying fruit flies could revolutionize diabetes research. Our second story focuses on how venom could form the basis of a new class of cancerfighting drugs.
Oncologists are melding magnetic resonance imaging (MRI) technology with a traditional ultrasound prostate exam to create a three-dimensional map of the prostate that allows physicians to view growths that were previously undetectable.
Playing with the portions of good and not-so-good-for-you foods is better than trying to eliminate bad foods, according to a new study. The idea is to not give up entirely foods that provide pleasure but aren’t nutritious.
In this episode of Bioscience Technology This Week, Rob Fee reports on the findings that researchers studying diabetes learned by observing grizzly bears. He also discusses a stem cell therapy that could lead to new and effective spinal cord injury treatments.
In this episode of Bioscience Technology This Week, News Editor Christina Jakubowski highlights the role of the protein GSK-3 in brain development and also reports that running, regardless of duration or speed, reduces death risk.
Scientists report they can crank up insect aggression simply by interfering with a basic metabolic pathway in the insect brain. Their study, of fruit flies and honey bees, shows a direct, causal link between brain metabolism (how the brain generates the energy it needs to function) and aggression.
A new study has found that a peptide called caerulein can convert existing cells in the pancreas into those cells destroyed in type 1 diabetes-insulin-producing beta cells.
On this episode of Bioscience Technology This Week, Editor-in-Chief Rob Fee reports on gold nanoparticles' promise in drug delivery. Our second story examines the work being done to decipher the wheat genome and the implications of this work.
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.
