Philadelphia, August 19, 2020 - A new study appearing in The American Journal of Medicine, published by Elsevier, calculates the lifetime risk of death from firearms and drug overdoses in the United States. The lifetime risk of death from firearms is about one percent, meaning that approximately one out of every 100 children will die from firearms if current death rates continue.
The rapid pace that invasive shrubs infiltrate forests in the northeastern United States makes scientists suspect they have a consistent advantage over native shrubs, and the first region-wide study of leaf timing, conducted by Penn State researchers, supports those suspicions.
AMHERST, Mass. - In a new paper this week, geographer Forrest Bowlick at the University of Massachusetts Amherst and colleagues at Texas A&M offer first-hand accounts of what is required for GIS instructors and IT administrators to set up virtual computing specifically for providing state-of-the-art geographic information systems (GIS) instruction.
In many ways, our childhood lays the foundation of our health in adult life. It is central to our physical and cognitive development. If this development is disturbed, it may have long-term consequences for our physical and mental health later in life.
In a new study, researchers from the Faculty of Health and Medical Sciences at the University of Copenhagen show that adversity in childhood increases the risk of premature death in early adulthood (16-36 years of age).
Through their basic research, physicians at the Heart Center of the University Hospital Bonn have discovered how the communication between individual cells can be influenced with the help of a specific protein. These findings are an important approach to improving the treatment of diseases such as arteriosclerosis (calcified blood vessels), which causes heart attacks. The study was published online in advance in the Journal of Extracellular Vesicles, the printed version will be published shortly.
The thylacine, that famous extinct Australian icon colloquially known as the Tasmanian Tiger, is revealed to have been only about half as big as once thought - not a "big" bad wolf after all.
Every year, 150 to 300 children in the United States are diagnosed with diffuse intrinsic pontine gliomas (DIPGs), aggressive and lethal tumors that grow deep inside the brain, for which there are no cures. In a study funded by the National Institutes of Health, researchers showed that experimental drugs designed to lower the body's natural production of alpha-ketoglutarate extended the lives of mice harboring DIPG tumors by slowing the growth of the cancer cells.
Using high-resolution data from the joint NASA-U.S. Geological Survey Landsat program, researchers have created the first map of the causes of change in global mangrove habitats between 2000 and 2016 - a valuable tool to aid conservation efforts for these vital coastline defenders.
Researchers around the world are on the hunt to find cheaper, better lithium-ion battery materials to power large scale machines, such as electric vehicles. One of their goals is to find alternative lithium-metal-oxide electrodes to those containing cobalt, an element common within phone and laptop batteries but too expensive and short on capacity to propel electric vehicles over long distances.
Stewart began looking at the effects of climate change on primate habitats with spatial data from the Coupled Model Intercomparison Project Phase 5, which estimates regional and seasonal temperature change per unit of CO2 emission, and range data of 426 separate primate species and subspecies, courtesy of the International Union for Conservation of Nature.
CHAMPAIGN, Ill. -- Imagine reading by the light of an exploded star, brighter than a full moon - it might be fun to think about, but this scene is the prelude to a disaster when the radiation devastates life as we know it. Killer cosmic rays from nearby supernovae could be the culprit behind at least one mass extinction event, researchers said, and finding certain radioactive isotopes in Earth's rock record could confirm this scenario.
With the number of extreme weather days rising around the globe in recent years due to global warming, it is no surprise that there has been an upward trend in hospital visits and admissions for injuries caused by high heat over the last several years. But cold temperatures are responsible for almost all temperature-related deaths, according to a new study published in the journal Environmental Research.
DURHAM, N.C. -- If you've ever been woken up before sunrise by the trilling and chirping of birds outside your window, you may have wondered: why do birds sing so loud, so early in the morning?
Researchers at Duke University say there may be a good reason why birds are most vocal at first light. By singing early and often, a new study suggests, birds perform better during the day.
The morning cacophony is mostly males, whose songs are meant to impress potential mates and rivals.
WASHINGTON, August 18, 2020 -- The novel coronavirus that causes COVID-19 is thought to spread through natural respiratory activities, such as breathing, talking and coughing, but little is known about how the virus is transported through the air.
University of Missouri scientists report, in Physics of Fluids, by AIP Publishing, on a study of how airflow and fluid flow affect exhaled droplets that can contain the virus. Their model includes a more accurate description of air turbulence that affects an exhaled droplet's trajectory.
LA JOLLA--Neutrophils are the warriors of the immune system. They are always ready to spring to action to help heal injuries or fight off disease. Unless, that is, something goes wrong in their developmental process.
Immature neutrophils aren't all warriors--they can be dangerous turncoats. High levels of immature neutrophils in the bloodstream can be a tell-tale sign of cancer and may even be a biomarker for COVID-19.
