While the pressures of climate change bring a sense of urgency to renewable energy development, a new study serves as a roadmap toward uniting the goals of a low-carbon future with that of ecological sustainability and conservation.
Coronaviruses like the one that causes COVID-19 are studded with protein "spikes" that bind with receptors on the cells of their victims - the first step in infection. Now scientists have made the first detailed images of those spikes in their natural state, while still attached to the virus and without using chemical fixatives that might distort their shape.
Hospitalized COVID-19 patients have a greater risk of dying if they are men or if they are obese or have complications from diabetes or hypertension, according to a new study conducted by University of Maryland School of Medicine (UMSOM) researchers. In a study published in the journal Clinical Infectious Diseases, the researchers evaluated nearly 67,000 hospitalized COVID-19 patients in 613 hospitals across the country to determine the link between certain common patient characteristics and the risk of dying from COVID-19.
While the SARS-CoV-2 virus has dominated the news this past year, researchers continue to study the health effects of the Zika virus, which has been reported in 86 countries globally.
The Zika virus is primarily transmitted by the bite of an infected mosquito from the Aedes genus. However, it can also be passed through sexual contact, blood transfusions, organ transplants, and between mother and baby during pregnancy. The virus has been documented to cause a range of birth defects, including microcephaly and various neurological, musculoskeletal, and eye abnormalities.
FAYETTEVILLE, Ark. - A University of Arkansas biologist is part of a global team of researchers developing a strategy to detect and intercept diseases emerging from wildlife in Africa that could eventually infect humans.
Assistant professor Kristian Forbes, along with colleagues from Africa, Europe and North America, have proposed a four-part approach to detect and contain zoonotic diseases, those that begin in animals but spillover into humans, like COVID-19 and HIV.
Researchers from the National Graphene Institute at the University of Manchester and the University of Pennsylvania have identified ultra-fast gas flows through the tiniest holes in one-atom-thin membranes, in a study published in Science Advances.
The work - alongside another study from Penn on the creation of such nano-porous membranes - holds promise for numerous application areas, from water and gas purification to monitoring of air quality and energy harvesting.
AMHERST, Mass. - In a new study of tidal marsh resilience to sea level rise, geologist and first author Brian Yellen at the University of Massachusetts Amherst and colleagues observed that Hudson River Estuary marshes are growing upward at a rate two to three times faster than sea level rise, "suggesting that they should be resilient to accelerated sea level rise in the future," he says.
URBANA, Ill. ¬- When agrochemical and pharmaceutical companies develop new products, they must test extensively for potential toxicity before obtaining regulatory approval. This testing usually involves lengthy and expensive animal studies.
A research team at University of Illinois has developed a gene biomarker identification technique that cuts the testing process down to a few days while maintaining a high level of accuracy.
Bacteria often show very strong biogeography - some bacteria are abundant in specific locations while absent from others - leading to major questions when applying microbiology to therapeutics or probiotics: how did the bacteria get into the wrong place? How do we add the right bacteria into the right place when the biogeography has gotten 'out of whack'?
Wearing a face covering in public is dependent upon how often people observe others wearing them, according to recent findings. Other important motivating factors are among findings of a national study undertaken by the U.S. Centers for Disease Control and Prevention through lead author Jack Barile, interim director of the Social Science Research Institute in University of Hawai'i at Mānoa's College of Social Sciences. More than 1,000 U.S. adults, ages 18 and older, who are representative of the U.S. population by gender, age, region, race/ethnicity and education, were surveyed.
In the aftermath of megafires that devastated forests of the western United States, attention turns to whether forests will regenerate on their own or not. Forest managers can now look to a newly enhanced, predictive mapping tool to learn where forests are likely to regenerate on their own and where replanting efforts may be beneficial.
A UCLA-led study may help explain how COVID-19 increases the risk for stroke. Scientists made the finding by running fluid spiked with a COVID-19-like protein through a 3D-printed model of the arteries of a patient who had suffered a stroke.
Although COVID-19 was first identified by its severe respiratory symptoms, the virus has caused strokes in young people who had no known risk factors. But little is known about how the virus increases the risk for stroke.
Plants have the same variation in body clocks as that found in humans, according to new research that explores the genes governing circadian rhythms in plants.
The research shows a single letter change in their DNA code can potentially decide whether a plant is a lark or a night owl. The findings may help farmers and crop breeders to select plants with clocks that are best suited to their location, helping to boost yield and even the ability to withstand climate change.
Researchers at The City College of New York have uncovered a novel way in which Vibrio cholerae, the aquatic microbe that causes cholera, may increase its competitive fitness, and the likelihood of creating pandemic strains of the bacteria.
More than a decade after committing $130+ billion to Closing the Gap, there has been little improvement in health outcomes experienced by Aboriginal and Torres Strait Islander populations.
A significant life expectancy gap remains, with cardiovascular disease the leading cause of death for Aboriginal and Torres Strait Islander women, responsible for almost 20 per cent of this gap.
So where have things gone wrong?
