WASHINGTON -- David Storm, a research physicist, and Tyler Growden, an electrical engineer, both with the U.S. Naval Research Laboratory, developed a new gallium nitride-based electrical component called a resonant tunneling diode (RTD) with performance beyond the anticipated speed of 5G.
The fifth-generation network technology is now just starting to roll out across the United States.
Storm and Growden's electronic component diode research findings were published March 19, 2020 in the academic journal Applied Physics Letters.
Hospital staff may be carrying SARS-CoV-2, the coronavirus that causes COVID-19 disease, without realising they are infected, according to a study by researchers at the University of Cambridge.
Researchers from Trinity College Dublin are calling on the government in Ireland to change recommendations for vitamin D supplements [Monday 11th May 2020].
A new publication from Dr Eamon Laird and Professor Rose Anne Kenny, School of Medicine, and the Irish Longitudinal Study on Ageing (TILDA), in collaboration with Professor Jon Rhodes at University of Liverpool, highlights the association between vitamin D levels and mortality from COVID-19.
Amsterdam, May 12, 2020 - The worldwide COVID-19 pandemic has infected more than 4 million people and killed close to 280,000.1 Finding a vaccine has become a global public health priority. However, creating a viable vaccine might take a long time; scientists estimate a vaccine may be available in between 12 and 18 months.
The question of whether democracies behave differently from non-democracies is a central, and intense, debate in the field of international relations. Two intellectual traditions - liberalism and realism - dominate. Liberals argue that democracies do indeed behave differently, while realists insist that regime type and ideology are of little relevance in understanding foreign policy behavior.
May 11, 2020, Alexandria, Va., USA--The Journal of Dental Research published today the results of a study that demonstrated that community water fluoridation is not associated with increased risk of osteosarcoma.
WOODS HOLE, Mass. -- Nearly a quarter of Americans suffer from arthritis, most commonly due to the wear and tear of the cartilage that protects the joints. As we age, or get injured, we have no way to grow new cartilage. Unlike humans and other mammals, the skeletons of sharks, skates, and rays are made entirely of cartilage and they continue to grow that cartilage throughout adulthood.
Early life experiences of zebra finches have a big effect on the construction of their first homes, according to a new study by researchers at the University of Alberta's Faculty of Science and the University of St Andrews' School of Biology.
The study shows that the presence of an adult bird as well as the types of materials available in early adolescence influence two key aspects of first-time nest building: material preference and construction speed.
New psychology research from the University of Konstanz reveals that stress changes the way we deal with risky information - results that shed light on how stressful events, such as a global crisis, can influence how information and misinformation about health risks spreads in social networks.
LAWRENCE -- Today, sea-level rise is a great concern of humanity as climate change warms the planet and melts ice sheets in Greenland and Antarctica. Indeed, great coastal cities around the world like Miami and New Orleans could be underwater later in this century.
AURORA, Colo. (May 12, 2020) - A woman's genetic make-up may cause her to gain weight when using a popular form of birth control, according to a study from researchers at the University of Colorado Anschutz Medical Campus.
CHAMPAIGN, Ill. -- Exhaustive seismic data from repeating earthquakes and new data-processing methods have yielded the best evidence yet that the Earth's inner core is rotating - revealing a better understanding of the hotly debated processes that control the planet's magnetic field.
The new study by researchers from the University of Illinois at Urbana-Champaign is published in the journal Earth and Planetary Science Letters.
The expansion of Medi-Cal, California's Medicaid program, gave millions of low-income Californians access to health insurance, but this study conducted in Northern California found that new patients may have to wait up up to a month for an appointment with a participating primary care provider, depending on their county of residence. It is not uncommon for Medi-Cal enrollees to visit emergency rooms if they require more immediate care.
A randomized controlled trial conducted by a research team at a primary care clinic at the Chinese University of Hong Kong indicates that intra-articular-only injection therapy with hypertonic dextrose is safe and effective for alleviating symptoms of knee osteoarthritis.
As strategies to curb gun violence at the federal level have stalled, leaders in primary care and health policy have identified the role doctors can play in national gun safety efforts and the prevention of firearm suicide. In this pair of recommendation papers, clinicians place themselves at the front lines of this public health issue and offer a call to action for the medical community. Both papers lay out a grassroots course of action to help physicians engage with their patients and policy makers.
