How dangerous is travel in the United States? It depends on how you frame the question. If it's risk per kilometer, the U.S. has 6.71 deaths per billion vehicle kilometers of travel compared to the United Kingdom, which has just 3.56 deaths per billion vehicle kilometers. This makes vehicular travel in the U.S. about 88.6 percent more dangerous than travel in the U.K. If it's risk per year of life, the U.S. has 10.25 deaths per 100,000 people whereas the U.K. has just 2.86 - a risk level of 257 percent, which is much higher than risk-per-kilometer.
14th of October, Hong Kong - Insilico Medicine, a biotechnology company developing an end-to-end drug discovery pipeline utilizing next-generation artificial intelligence, is proud to present its paper "A Prior of a Googol Gaussians: a Tensor Ring Induced Prior for Generative Models" at the 33rd Conference on Neural Information Processing Systems (NeurIPS).
Wrapping a building in a fire-protective blanket is a viable way of protecting it against wildfires, finds the first study to scientifically assesses this method of defense.
Traumatic brain injuries (TBI), including concussions, can be caused by anything from sports injuries to battlefield trauma. And they can have fatal or lasting effects. The results of a severe concussion--problems with thinking, memory, movement, emotions--are clear. The causes, or underlying pathological mechanisms, were not.
CAMBRIDGE, MA -- More than 200 square meters of our bodies -- including the digestive tract, lungs, and urinary tract -- are lined with mucus. In recent years, scientists have found some evidence that mucus is not just a physical barrier that traps bacteria and viruses, but it can also disarm pathogens and prevent them from causing infections.
PHILADELPHIA -- Women who are health policy or health services researchers face a significant disparity in social media influence compared to their male peers, according to a new study from researchers in the Perelman School of Medicine at the University of Pennsylvania. Although the average number of tweets among all researchers tend to be consistent, women trail behind men in follower counts, regardless of how active they are on Twitter.
Bottom Line: This research letter uses updated national survey data for 2018 to estimate how common electronic cigarette use is among adults 18 and older in the United States. The analysis included about 153,000 survey participants, of whom 55% were women. The authors report that while current e-cigarette use decreased from 3.7% in 2014 to 2.8% in 2017, it increased again in 2018 to 3.2%. The biggest increase between 2017-2018 was among young adults aged 18 to 24 years (5.2% in 2017 vs. 7.6% in 2018), with no such increase among middle-age or older adults.
Secondary metabolites - the compounds produced by microbes to mediate internal and external messaging, self-defense, and chemical warfare - are the basis for hundreds of invaluable agricultural, industrial, and medical products. And given the increasing pace of discovery of new, potentially valuable secondary metabolites, it's clear that microbes have a great deal more to offer.
Topological insulators are innovative materials that conduct electricity on the surface, but act as insulators on the inside. Physicists at the University of Basel and the Istanbul Technical University have begun investigating how they react to friction. Their experiment shows that the heat generated through friction is significantly lower than in conventional materials. This is due to a new quantum mechanism, the researchers report in the scientific journal Nature Materials.
Scientists at Lancaster University and the University of Oxford have created a nano-electronic circuit which vibrates without any external force.
Using a tiny suspended wire, resembling a vibrating guitar string, their experiment shows how a simple nano-device can generate motion directly from an electrical current. The research has been published in Nature Physics.
In a new study, UC San Francisco scientists used maps of brain connections to predict how brain atrophy would spread in individual patients with frontotemporal dementia (FTD), adding to growing evidence that the loss of brain cells associated with dementia spreads via the synaptic connections between established brain networks. The results advance scientists' knowledge of how neurodegeneration spreads and could lead to new clinical tools to evaluate how well novel treatments slow or block the predicted trajectory of these diseases.
Irvine, Calif. - Researchers at the University of California, Irvine have developed a new scanning transmission electron microscopy method that enables visualization of the electric charge density of materials at sub-angstrom resolution.
New research from North Carolina State University shows that unique materials with distinct properties akin to those of gecko feet - the ability to stick to just about any surface - can be created by harnessing liquid-driven chaos to produce soft polymer microparticles with hierarchical branching on the micro- and nanoscale.
The findings, described in the journal Nature Materials, hold the potential for advances in gels, pastes, foods, nonwovens and coatings, among other formulations.
Lehigh University's Department of Bioengineering is presenting 26 poster and lecture sessions at the annual meeting of the Biomedical Engineering Society (BMES), October 16-19, 2019, in Philadelphia. See below for a complete list of presentations by Lehigh bioengineering faculty, graduate, and undergraduate students at BMES 2019.
Tokyo, Japan - Scientists from Tokyo Metropolitan University have created a new layered superconducting material with a conducting layer made of bismuth, silver, tin, sulfur and selenium. The conducting layer features four distinct sublayers; by introducing more elements, they were able to achieve unparalleled customizability and a higher "critical temperature" below which superconductivity is observed, a key objective of superconductor research. Their design strategy may be applied to engineer new and improved superconducting materials.
