Repeated exposure to high-stress calls for service and ongoing exposure to stress without relief were two of the contributing factors that could lead law enforcement officers to become susceptible to adverse events while performing their duties, according to a new study published in BMC Public Health by researchers at The University of Texas Health Science Center at Houston (UTHealth).
ABERDEEN PROVING GROUND, Md. -- Army and Texas A&M University researchers developed a new material that can autonomously heal in air and underwater.
The first-of-its-kind, 3-D printable and stimuli-responsive polymeric materials are expected to enable massive reconfigurability in future military platforms, which opens new opportunities for morphing unmanned air vehicles and robotic platforms, said Dr. Frank Gardea, an aerospace engineer and principal investigator of this work for the U.S. Army's Combat Capabilities Development Command's Army Research Laboratory.
Amsterdam, NL, August 18, 2020 - Traumatic brain injury (TBI) is a leading cause of death and disability. Post-injury distress is common, with many individuals experiencing chronic anxiety and depressive symptoms as well as chronic pain.
An increased level of fructose intake during pregnancy can cause significant changes in maternal metabolic function and milk composition and alter the metabolism of their offspring, researchers from the University of Otago, Wellington, have found.
Atomically thin diamond, also called diamane, is a two-dimensional carbon allotrope and has attracted considerable scientific interest due to its potential physical properties. However, previous studies suggest that atomically thin diamond films are not achievable in a pristine state because diamonds possess a three-dimensional crystalline structure and would lack chemical stability when thinned down to the thickness of diamond's unit cell due to the dangling sp3 bonds.
We are surrounded by electronic devices. Transistors are used to power telephones, computers, televisions, hi-fi systems and game consoles as well as cars, airplanes and the like. Today's silicon-based electronics, however, consume a substantial and ever-increasing share of the world's energy. A number of researchers are exploring the properties of materials that are more complex than silicon but that show promise for the electronic devices of tomorrow - and that are less electricity-hungry.
Psychosocial needs of people affected by cancer are not being adequately met due to the disruption in services caused by Covid-19, a new report in the journal Psycho-Oncology reports.
During this unique study, researchers from six universities, as part of their work on the British Psychosocial Oncology Society Executive Committee, investigated how psychosocial support for those affected by cancer was impacted during the current Covid-19 pandemic.
Experts estimate up to one third of people attending specialist memory clinics could have a condition that is commonly mistaken for early dementia.
In a paper published in the journal, Brain, UK academics and clinicians have collaborated to develop a diagnostic definition of the widely recognised but poorly understood condition, Functional Cognitive Disorder (FCD).
Excessive nutrients, such as nitrogen and phosphorus, have devastating effects on coastal marine ecosystems by causing algal blooms that deplete oxygen in the water, killing marine life. Such nutrients can enter the sea in wastewater or run-off from agricultural land.
Have you heard of DNA? It stands for Do Not Abbreviate apparently. Jokes aside, it's the most widely used acronym in scientific literature in the past 70 years, appearing more than 2.4 million times.
The short form of deoxyribonucleic acid is widely understood, but there are millions more acronyms (like WTF: water-soluble thiourea-formaldehyde) that are making science less useful and more complex for society, according to a new paper released by Australian researchers.
Anti-vaccine websites, which could play a key role in promoting public hesitancy about a potential COVID vaccine, are far more likely to be found via independent search engines than through an internet giant like Google.
The study, led by researchers at Brighton and Sussex Medical School (BSMS), showed that independent search engines returned between 3 and 16 anti-vaccine websites in the first 30 results, while Google.com returned none.
Researchers from the Marine Biology Laboratory of the University of Seville, led by Professor José Carlos García Gómez, have studied the factors involved in fish reproduction and breeding in the Gulf of Cadiz. Their analysis focused on estuaries which, due to their specific conditions, created by the mixing of river and sea water, are especially favourable for the reproductive function of the species in the area.
As the uncertainty around reopening college and university campuses this fall continues, those who work, study, teach and conduct research are navigating the uncertain terrain of the "new normal." They are balancing physical distancing and other COVID-19 prevention practices with productivity, creating home workspaces and mastering communications and teamwork across time and space.
Researchers at Ruhr-Universität Bochum have developed a new catalyst that can catalyse reactions to produce pharmaceuticals or chemicals used in agriculture. It creates carbon-carbon bonds between what are known as organolithium compounds without creating any unwanted by-products. The team led by Professor Viktoria Däschlein-Gessner, Inorganic Chemistry II Research Group, describes the results in the journal Angewandte Chemie, published online on 29 July 2020.
Indispensable for many applications
New Haven, Conn. -- Yale physicists have developed an error-correcting cat -- a new device that combines the Schrödinger's cat concept of superposition (a physical system existing in two states at once) with the ability to fix some of the trickiest errors in a quantum computation.
It is Yale's latest breakthrough in the effort to master and manipulate the physics necessary for a useful quantum computer: correcting the stream of errors that crop up among fragile bits of quantum information, called qubits, while performing a task.
