New Rochelle, NY, January 6, 2021--Women physicians feel pressured to spend more time in work-related citizenship tasks, based largely on their age and race. Nearly half of women perceived that they spent more time on citizenship tasks than their male colleagues, according to a study in Journal of Women's Health. Click here to read the article now.
They are as thin as a hair, only a hundred thousand times thinner--so-called two-dimensional materials, consisting of a single layer of atoms, have been booming in research for years. They became known to a wider audience when two Russian-British scientists were awarded the Nobel Prize in Physics in 2010 for the discovery of graphene, a building block of graphite. The special feature of such materials is that they possess novel properties that can only be explained with the help of the laws of quantum mechanics and that may be relevant for enhanced technologies.
LA JOLLA--New data suggest that nearly all COVID-19 survivors have the immune cells necessary to fight re-infection.
The findings, based on analyses of blood samples from 188 COVID-19 patients, suggest that responses to the novel coronavirus, SARS-CoV-2, from all major players in the "adaptive" immune system, which learns to fight specific pathogens, can last for at least eight months after the onset of symptoms from the initial infection.
E. coli food poisoning is one of the worst food poisonings, causing bloody diarrhea and kidney damage. But all the carnage might be just an unintended side effect, researchers from UConn Health report in the 27 November issue of Science Immunology. Their findings might lead to more effective treatments for this potentially deadly disease.
Physicians have long known that necrotizing enterocolitis (NEC), a potentially lethal inflammatory condition that destroys a premature infant's intestinal lining, is often connected to the development of severe brain injury in those infants who survive. However, the means by which the diseased intestine "communicates" its devastation to the newborn brain has remained largely unknown.
DURHAM, N.C. -- Before the pandemic, one-third of U.S. households with children were already "net worth poor," lacking enough financial resources to sustain their families for three months at a poverty level, finds new research from Duke University.
In 2019, 57 percent of Black families and 50 percent of Latino families with children were poor in terms of net worth. By comparison, the rate for white families was 24 percent.
The North Sea is a heavily trafficked area, with major shipping routes crossing its waters, and fisheries, offshore oil rigs, and wind farms populating its waves. All this activity inevitably has an effect on marine wildlife, and scientists are particularly interested in how the harbor porpoise population has fared in the face of such disturbances.
A systematic review and meta-analysis of international COVID-19 literature, led by UNSW Sydney, has confirmed that while children under five years old were likely to recover from the infection, half of those infected were infants and almost half of the infected under-fives were asymptomatic.
A new SFU-led study finds that about half of media stories in early 2020 featuring COVID-19 "preprint" research--research that has not yet been peer-reviewed--accurately framed the studies as being preprints or unverified research.
HKUST researchers discover a novel mechanism of recruiting ARF family proteins to specific subcellul
The small GTPases of the ADP-ribosylation factor (Arf) family are key initiators of various physiological processes including secretion, endocytosis, phagocytosis and signal transduction. Arf family proteins function to mediate recruitment of cytosolic effectors to specific subcellular compartments. This process facilitates Arf effectors to perform cargo recognition, lipid modification or other cellular functions. Blocking the activities of Arf family proteins inhibits secretion of important molecules from the cell and also inhibits cellular uptake of nutrients.
Given a list of cities and the distances between each pair of cities, how do you determine the shortest route that visits each city exactly once and returns to the starting location? This famous problem is called the "traveling salesman problem" and is an example of a combinatorial optimization problem. Solving these problems using conventional computers can be very time-consuming, and special devices called "quantum annealers" have been created for this purpose.
In the future, the Antarctic could become a greener place and be colonised by new species. At the same time, some species will likely disappear. 25 researchers recently presented these and many other findings in a major international project, in which they analysed hundreds of articles on the Antarctic published in the past ten years. By doing so, the team have provided an exceptionally comprehensive assessment of the status quo and future of Antarctica and the Southern Ocean that surrounds it.
Smoking is associated with an increased risk of COVID-19 symptoms and smokers are more likely to attend hospital than non-smokers, a study has found.
The study published today in Thorax, by researchers from King's College London, investigates the association between smoking and the severity of the COVID-19.
A new review by Swansea University reveals there is widespread belief, around the world, in a teaching method that is not only ineffective but may actually be harmful to learners.
For decades educators have been advised to match their teaching to the supposed 'learning styles' of students. There are more than 70 different classification systems, but the most well-known (VARK) sees individuals being categorised as visual, auditory, read-write or kinesthetic learners.
Researchers who studied antibody and immune cell responses in more than 180 men and women who had recovered from COVID-19 report these patients' immune memory to the virus - across all immune cell types studied - was measurable for up to 8 months after symptoms appeared. The results indicate "that durable immunity against secondary COVID-19 disease is a possibility in most individuals," the authors say.
