BEER-SHEVA...May 20, 2019 - The first experimental robot drone that flies like a typical quadcopter, drives on tough terrain and squeezes into tight spaces using the same motors, has been developed by Ben-Gurion University of the Negev (BGU) researchers.
ANN ARBOR, Mich. -- Despite evidence that helmets are critical to preventing head injuries, not all children wear them while biking, skateboarding and riding scooters, a new national poll finds.
Eighteen percent of parents say their child never wears a helmet on a bike ride, and even more say their kids skip helmets on a skateboard (58 percent) and scooter (61 percent), suggests the C.S. Mott Children's Hospital National Poll on Children's Health at the University of Michigan.
Your smile, and associated oral health, may be a factor for successfully passing through the revolving doors of life. It is your first impression to a stranger, the closing argument to land a job and a major factor to achieving a good quality of life. For those who struggle with substance use disorder, oral health often falls off the precipice of self-care thereby seriously damaging interpersonal skills, while causing poor nutrition, increased oral and general infections and debilitating oral pain.
A new laboratory-based method of estimating outcomes for patients with a severe pulmonary disorder that has no cure can help physicians better provide proper care, referrals, and services for patients at the end of life, according to a new study of more than 17,000 patients from Intermountain Healthcare.
PITTSBURGH, May 19, 2019 - Reversibly paralyzing and heavily sedating hospitalized patients with severe breathing problems do not improve outcomes in most cases, according to a National Institutes of Health-sponsored clinical trial conducted at dozens of North American hospitals and led by clinician-scientists at the University of Pittsburgh and University of Colorado schools of medicine.
CHAMPAIGN, Ill. -- Recyclable plastics that contain ring-shaped polymers may be a key to developing sustainable synthetic materials. Despite some promising advances, researchers said, a full understanding of how to processes ring polymers into practical materials remains elusive. In a new study, researchers identified a mechanism called "threading" that takes place when a polymer is stretched - a behavior not witnessed before. This new insight may lead to new processing methods for sustainable polymer materials.
Gastric cancer, Q fever, Legionnaires' disease, whooping cough--though the infectious bacteria that cause these dangerous diseases are each different, they all utilize the same molecular machinery to infect human cells. Bacteria use this machinery, called a Type IV secretion system (T4SS), to inject toxic molecules into cells and also to spread genes for antibiotic resistance to fellow bacteria. Now, researchers at Caltech have revealed the 3D molecular architecture of the T4SS from the human pathogen Legionella pneumophila with unprecedented details.
Machine learning (ML), a form of artificial intelligence that recognizes faces, understands language and navigates self-driving cars, can help bring to Earth the clean fusion energy that lights the sun and stars. Researchers at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) are using ML to create a model for rapid control of plasma -- the state of matter composed of free electrons and atomic nuclei, or ions -- that fuels fusion reactions.
When it comes to pitching business ideas to potential investors, an entrepreneur's excitement and enthusiasm can be the difference between dreams taking shape or ultimately falling flat.
But it's not just the intensity of enthusiasm that's important, according to a recent study by a team led by Georgia Institute of Technology researchers. How long an entrepreneur displays the highest level of excitement during a pitch also plays a major role in predicting success in receiving funding.
Basically, too much enthusiasm can be a bad thing.
UPTON, NY--From the ancient pyramids to modern buildings, various three-dimensional (3-D) structures have been formed by packing shaped objects together. At the macroscale, the shape of objects is fixed and thus dictates how they can be arranged. For example, bricks attached by mortar retain their elongated rectangular shape. But at the nanoscale, the shape of objects can be modified to some extent when they are coated with organic molecules, such as polymers, surfactants (surface-active agents), and DNA.
