If you're about to run headfirst into something, your reflex might be to tense your neck and stabilize your noggin. But according to new research from Stanford University that may not be the best way to stave off a concussion. Instead, the findings suggest that your head's position is more important than whether you are tensing your neck.
It all comes down to how your head accelerates backward after impact, which some think is the major factor controlling concussion risk. The work was published Aug. 20 in IEEE Transactions on Biomedical Engineering.
PITTSBURGH--One of the oldest, most versatile and inexpensive of materials - paper - seemingly springs to life, bending, folding or flattening itself, by means of a low-cost actuation technology developed at Carnegie Mellon University's Human-Computer Interaction Institute.
WASHINGTON -- Nearly six percent of urinary tract infections analyzed by a California emergency department were caused by drug-resistant bacteria in a one-year study period, according to new research in Annals of Emergency Medicine. The bacteria were resistant to most of the commonly used antibiotics. And, in many cases, patients had no identifiable risk for this kind of infection, the study found.
Remember the scene in the movie Mission: Impossible when Tom Cruise has to sneak into the vault? He had to do all sorts of moves to avoid detection. That's what it's like to sneak a targeted drug into a kidney and keep it from getting eliminated from the body.
Since kidneys are the filtering agents in our body, they are keen to get rid of small particles that they sense do not belong. And if the kidney does not filter out a particle, excreting it through urine, it may be eliminated by the liver, which uses macrophages to search for and get rid of foreign bodies.
Antibiotics - medicines that treat bacterial infections - have saved millions of lives worldwide since their discovery in the early 20th century. When we fill a prescription at the doctor's office or pharmacy today, most of us take for granted that these commonly prescribed medicines are real, and of good quality.
Aug. 21, 2018 -- In the future, your car windshield could become a giant camera sensing objects on the road. Or each window in a home could be turned into a security camera.
University of Utah electrical and computer engineers have discovered a way to create an optics-less camera in which a regular pane of glass or any see-through window can become the lens.
SAN FRANCISCO--August 20, 2018--To fight viral infections, your immune system calls on CD8 T cells to kill the infected cells. The CD8 T cells can also be used in immunotherapy approaches to kill cancer cells, including the CAR T cell therapy currently attracting broad public attention.
BROOKLYN, New York, Monday, August 21, 2018 - The worldwide market for 3D-printed parts is a $5 billion business with a global supply chain involving the internet, email, and the cloud - creating a number of opportunities for counterfeiting and intellectual property theft.
BOSTON, Aug. 19, 2018 -- Many people rely on contact lenses to improve their vision. But these sight-correcting devices don't last forever -- some are intended for a single day's use -- and they are eventually disposed of in various ways. Now, scientists are reporting that throwing these lenses down the drain at the end of their use could be contributing to microplastic pollution in waterways.
CHARLOTTESVILLE, Va. - University of Virginia mechanical engineers and materials scientists, in collaboration with materials scientists at Penn State, the University of Maryland and the National Institute of Standards and Technology, have invented a "switching effect" for thermal conductivity and mechanical properties that can be incorporated into the fabrication of materials including textiles and garments.
