This is the first example of a novel mode of neurotransmitter-based communication and challenges current dogma about mechanisms of signaling in the brain. The findings uncover new pathways for developing therapies for disorders like epilepsy, anxiety and chronic pain.
Each time a blood vessel splits into smaller vessels, red blood cells (RBCs) are presented with the same decision: Take the left capillary or the right. While one might think RBCs would divide evenly at every fork in the road, it is known that at some junctures, RBCs seem to prefer one vessel over the other. One new computer model looks to determine why RBCs behave this way, untangling one of the biggest mysteries in our vascular system
If you want to know how to make a sneaker with better traction, just ask a snake. That's the theory driving the research of Hisham Abdel-Aal, PhD, an associate teaching professor from Drexel University's College of Engineering who is studying snake skin to help engineers improve the design of textured surfaces, such as engine cylinder liners, prosthetic joints - and yes, maybe even footwear.
While humans can only broadcast about one percent of their vocal power through their speech, some animals and mammals are able to broadcast 100 percent. The secret to their long-range howls? A combination of high pitch, a wide-open mouth and a clever use of the body's shape to direct sound -- none of which are factors that humans can replicate.
In a discovery that points to potential new antibiotic medicines, scientists from Rice University and the University of Michigan have deciphered the workings of a common but little-understood bacterial switch that cuts off protein production.
Using a new mode of atomic force microscopy, researchers at EPFL have found a way to see and measure protein assembly in real time and with unprecedented detail.
A rare genetic disorder in which people are suddenly overcome with profound weakness or temporary paralysis is caused by a hole in a membrane protein that allows sodium ions to leak across cell membranes. The results of a new study reveal the mechanisms of periodic paralysis at the atomic level and suggest designs for drugs that may prevent this ion leak and provide relief to these patients
Researchers in Bochum have deployed a novel infrared (IR) microscope with quantum cascade lasers in order to analyze tissue samples taken during routine clinical procedures for colorectal cancer diagnosis. The IR microscope used to date had not yet established itself as a diagnostic tool in hospitals, as the analyses used to take too long. By utilizing the new laser technology, the researchers reduced the time required for analysis from one day to a few minutes.
Fresh insight into how the brain responds to medically induced cooling -- routinely used to limit head injury -- could inform treatments for related conditions and help babies at risk of birthing complications.
Rutgers University-New Brunswick engineers have created a 3D-printed smart gel that walks underwater and grabs objects and moves them. The watery creation could lead to soft robots that mimic sea animals like the octopus, which can walk underwater and bump into things without damaging them. It may also lead to artificial heart, stomach and other muscles, along with devices for diagnosing diseases, detecting and delivering drugs and performing underwater inspections.
