Scientists found antibodies to Ebola virus in people up to a year before the 2018 Ebola virus disease outbreak began in the Eastern Democratic Republic of Congo, or DRC. This suggests that either early cases may have been missed or that exposure occurs more commonly than previously thought, according to a study led by the University of California, Davis.
NEW YORK -- Our minds can help us make decisions by contemplating the future and predicting the consequences of our actions. Imagine, for instance, trying to find your way to a new restaurant near your home. Your brain can build a mental model of your neighborhood and plan the route you should take to get there.
Dicamba has been the subject of lawsuits across the country, with landowners contending the herbicide, when used by neighboring growers, has blown onto their property, killing valuable non-resistant crops.
Some people refer to the Himalaya-Tibetan Plateau as the "third pole" because the region has the largest reserve of glacial snow and ice outside of the north and south poles. The glaciers, which are extremely sensitive to climate change and human influence, have been retreating over the past decade. Now, researchers reporting in ACS' Environmental Science & Technology Letters have detected light-absorbing "tarballs" in the Himalayan atmosphere, which could contribute to glacial melt.
Along with Europe and North America, East Asia has in the past few decades become one of the three largest nitrogen deposition centers in the world. This can lead to considerable impacts on the structure and function of ecosystems; for instance, excessive nitrogen is thought to be one of the drivers of biodiversity change across the globe; and nitrogen deposition can also cause acidification of soils and water. Consequently, it is important to study the carbon-nitrogen cycle in East Asia.
Among the most extreme planets discovered beyond the edges of our solar system are lava planets: fiery hot worlds that circle so close to their host star that some regions are likely oceans of molten lava. According to scientists from McGill University, York University, and the Indian Institute of Science Education, the atmosphere and weather cycle of at least one such exoplanet is even stranger, featuring the evaporation and precipitation of rocks, supersonic winds that rage over 5000 km/hr, and a magma ocean 100 km deep.
More evidence has emerged to support stricter coastal management, this time focusing on pollution and overfishing in the picturesque tourist waters off Auckland in New Zealand.
A study of common dolphins (Delphinus delphis) in the Hauraki Gulf connects their diet with the prevalence of commercial fishing and water quality - emphasising the need to carefully manage marine parks and surrounding environments to prevent overfishing and extensive nutrient runoff.
Wellesley, MA -- A new study published in the Journal of Adolescent Health found that checking social media often, viewing emotional or violent videos, and starting to use social media at an early age were significantly related to later bedtimes and fewer hours of sleep on school nights for early adolescents.
Beta-blockers could potentially be used to treat COVID-19, according to a new international study by Italian and Australian scientists.
University of South Australia cancer researcher, Dr Nirmal Robinson, working with a team in Naples, has found evidence in animal models that the beta-blocker Propranolol helps suppress the spread of cancer in the lung which has an inflammatory profile very similar to COVID-19.
The scientists have presented their findings in a paper published in Frontiers in Immunology, calling for clinical trials to support their research.
WASHINGTON, November 3, 2020 -- The ongoing COVID-19 pandemic has led many researchers to study airborne droplet transmission in different conditions and environments. The latest studies are starting to incorporate important aspects of fluid physics to deepen our understanding of viral transmission.
Durham, NC -Each year ligament injuries sideline thousands of athletes and regular citizens. Recovery is long and painful, and sometimes a return to full function is never realized due to scar formation - a factor that makes ligament injuries prone to further damage. A new exosomes study released today in STEM CELLS may lead to a welcomed solution in the future.
Using artificial intelligence, UCPH researchers have solved a problem that until now has been the stumbling block for important protein research into the dynamics behind diseases such as cancer, Alzheimer's and Parkinson's, as well as in the development of sustainable chemistry and new gene-editing technologies.
Many diseases caused by common plant viruses reduce the crops of important food plants. In the worst case, potato viruses, among others, can destroy as much as 80% of crops on infected fields.
Plants are not entirely defenceless against viruses, although they lack an immune system like the one found in humans. For plant cells, the primary defence mechanism against viral infections is gene silencing. By utilising the mechanism, plant cells identify the foreign genetic material originating in the virus and cut it up into small pieces.
The UPV/EHU's research group OPIK, Social Determinants of Health and Demographic Change, is a multidisciplinary group comprising research personnel in the field of social and health sciences; it explores the social factors influencing health and disease in the population, social inequalities in health and the policies that have the potential to modify these social determinants in the interests of improving the health of the population.
How biodiversity is generated and maintained are central questions in science, which are becoming increasingly important for our quality of life. How do similar species coexist in a system? Which ones will dominate or be excluded? Will the system succumb to invasion by outsiders? Can we predict these interactive dynamics in systems with many different species?
