Masdar Institute Faculty Explores Clean Energy Cooperation Opportunities between UAE and China to Bolster United Nations’ Efforts to Achieve Sustainable Development Goals.
University of Arkansas physicists are able to accurately describe the geometric structure of gold nanobars, enabling more precise coupling of plasmonic nanostructures with light.
TUSCALOOSA, Ala. — Spring is here and summer is near, and with the increase in warm weather comes bloodsuckers. No, not vampires, but to some they cause just as much dread. It’s time for ticks, the long lost cousins of spiders and scorpions and the brothers of mites, to have their season, and Dr. John Abbott, director of museum research & collections at The University of Alabama Museums, has the low-down on what types are prevalent in the South, what they do, the dangers they pose, how to avoid them and what to do if bitten by one.
It may be surprising to learn that much remains unknown about radiation’s effects on materials. To find answers, Massachusetts Institute of Technology researchers are developing techniques to explore the microstructural evolution and degradation of materials exposed to radiation. They report a dynamic option, this week in Applied Physics Letters, to continuously monitor the properties of materials being exposed to radiation during the exposure. This provides real-time information about a material’s microstructural evolution.
A new simulation based on the von-Kármán-Sodium (VKS) dynamo experiment takes a closer look at how the liquid vortex created by the device generates a magnetic field. Researchers investigated the effects of fluid resistivity and turbulence on the collimation of the magnetic field, where the vortex becomes a focused stream. They report their findings this week in the journal Physics of Fluids.
The most established plasma propulsion concepts are gridded-ion thrusters that accelerate and emit a larger number of positively charged particles than those that are negatively charged. To enable the spacecraft to remain charge-neutral, a “neutralizer” is used to inject electrons to exactly balance the positive ion charge in the exhaust beam. However, the neutralizer requires additional power from the spacecraft and increases the size and weight of the propulsion system. Researchers are investigating how the radio-frequency self-bias effect can be used to remove the neutralizer altogether, and they report their work in this week’s Physics of Plasmas.
Materials exposed to neutron radiation tend to experience significant damage. At the nanoscale, these incident neutrons collide with a material’s atoms, which then collide with each other. The resulting disordered atomic network resembles those seen in some glassy materials, which has led many in the field to use them in nuclear research. But the similarities between the materials may not be as useful as previously thought, according to this week’s The Journal of Chemical Physics.
ASN Denounces Administration’s Proposed Massive Cuts for the National Institutes of Health – “Would Disrupt Medical Research”
Wolters Kluwer, a leading global provider of information and point of care solutions for the healthcare industry, is pleased to announce the 10th Edition of Kaplan and Sadock’s Comprehensive Textbook of Psychiatry. This marks the 50th anniversary of this cornerstone text, which covers the full range of psychiatry and mental health.
By providing UK Orofacial Pain Clinic patients with a smartphone application that teaches diaphragmatic breathing, a team from the UK Center for Research on Violence Against Women hypothesizes victims of sexual and physical violence will learn to regulate their body’s sympathetic (flight or fight) tone and manage their pain.
Working in the Texas A&M’s Cyberphysical Systems Laboratory, Dr. P.R.Kumar, University Distinguished Professor in the Department of Electrical and Computer Engineering, along with graduate students Bharadwaj Satchidanandan and Woo-Hyun Ko, have applied the theory of dynamic watermarking of sensors in autonomous vehicles to prevent malicious attacks.
Mobility researchers at the University of Michigan have devised a new way to test autonomous vehicles that bypasses the billions of miles they would need to log for consumers to consider them road-ready
Political and economic unrest, not religion or ethnicity, are often the causes of terrorist attacks like the one in Manchester, England. The response should not just center on increasing military action and security reinforcement , according to a West Virginia University expert in social and psychological responses to terrorism and other threats.
First, diesel vehicles tainted their reputation with soot particles, then high nitric oxide emissions. So are owners of new gasoline cars environmentally friendly? Not always, says a new study led by Empa scientists: some direct-injection gasoline engines emit just as many soot particles as unfiltered diesel cars did in the past. Particle filters can remedy this.
Online pulmonary rehabilitation for patients with chronic obstructive pulmonary disease (COPD) was found to be as effective as face-to-face rehabilitation programs at improving patients’ exercise capacity and symptom control, according to new research presented at the 2017 American Thoracic Society International Conference.
In a new study, CT-measured vascular pruning – the diminution of distal pulmonary blood vessels (vessels on the outer edges of the lungs) – was associated with increased risk of death in smokers without chronic obstructive pulmonary disease (COPD). The study was presented at the 2017 American Thoracic Society International Conference.
A study led by the University of Birmingham has made a breakthrough in the understanding of how different genetic mutations cause acute myeloid leukaemia.
In an effort to find new strategies to personalize treatment for pediatric patients, Seattle Children’s has opened the first clinical trial applying precision medicine to better understand how the immune system drives both inflammatory bowel disease and graft-versus host disease in pediatric patients.
Two B-25 bombers associated with American servicemen missing in action from World War II were recently documented in the waters off Papua New Guinea by Project Recover—a collaborative team of marine scientists, archaeologists and volunteers who have combined efforts to locate aircraft and associated MIAs from World War II.
Most Americans — even average Democrats — do not accept the argument that voter identification laws can suppress voter turnout, according to a new study that includes a University of Kansas professor.
