Portland State University researchers who published an article three years ago in the New England Journal of Medicine about the presence of previously undiscovered forms of formaldehyde in e-cigarette vapor revisited their research and found that formaldehyde risks were even higher than they originally thought.
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
The vibrational motion of an atom in a crystal propagates to neighboring atoms, which leads to wavelike propagation of the vibrations throughout the crystal. The way in which these natural vibrations travel through the crystalline structure determine fundamental properties of the material. Now, researchers have shown that by swapping out just a small fraction of a material's atoms with atoms of a different element, they can control the speed and frequencies of these vibrations
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.
NASA and private company SpaceX plan to send humans to Mars within the next 15 years--but need to figure out how to protect astronauts from the dangerous cosmic radiation of deep space. Now the lab of UCSF neuroscientist Susanna Rosi, PhD, has identified a potential treatment for the brain damage caused by cosmic rays--a drug that prevents memory impairment in mice exposed to simulated space radiation. The study was published May 18, 2018 in Scientific Reports.
In the world of robotics, soft robots are the new kids on the block. The unique capabilities of these automata are to bend, deform, stretch, twist or squeeze in all the ways that conventional rigid robots cannot. Today, it is easy to envision a world in which humans and robots collaborate -- in close proximity -- in many realms. Emerging soft robots may help to ensure that this can be done safely, and in a way that syncs to human environments or even interfaces with humans themselves.
Don't use flammable materials and you won't have fires. Good idea but not very practical or realistic. Better option: reduce the flammability of numerous materials and make more fire-safe products through scientific study directed by a new research roadmap published by the National Institute of Standards and Technology (NIST).
A 10-fold increase in the ability to harvest mechanical and thermal energy over standard piezoelectric composites may be possible using a piezoelectric ceramic foam supported by a flexible polymer support, according to Penn State researchers.
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.
