Osaka, Japan - Most tissues of the body have the extraordinary ability to heal themselves upon injury. But sometimes something goes awry during the complex process of wound healing and the tissue forms too much connective tissue, also called fibrosis, around the injured area, which can result in the organ not functioning properly. Now, researchers from Osaka University have identified a novel protein that plays a central role in the development of such excess scar tissue.
More than 30 significant risk factors have been identified for the development of psychotic disorders in offspring in research led by the NIHR Maudsley BRC. It is the first comprehensive meta-analysis of pre- and perinatal risk factors for psychosis in nearly 20 years.
March 24, 2020-- In a new study of patients with severe COVID-19 (SARS-CoV-2) hospitalized on ventilators, researchers found that lying face down was better for the lungs. The research letter was published online in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.
When one thinks of measuring something, the first idea that comes to mind is that of taking a tool, such as a caliper, reaching out to a specific place or thing, and noting down a number. There is no doubt that, in many domains of engineering and science, taking reliable measurements at well-defined locations is fundamentally important. However, this is changing in today's connected world because we attempt to distribute technology everywhere for improving sustainability.
Plenty of fictional works like Mary Shelly's Frankenstein have explored the idea of swapping out a brain from one individual and transferring it into a completely different body. However, a team of biologists and engineers has now used a variation of the sci-fi concept, via computer simulation, to explore a core brain-body question.
Researchers at the HSE Institute of Education have used regional data to describe, for the first time in Russia, how inequality in access to education affects different parts of the Russian Federation. The research findings reveal that the key determining factors are the local economy and the proportion of people with a university degree: urbanised regions with well-developed economies and educated inhabitants are more likely to have good-quality schools, with a large proportion of students scoring highly in the Unified State Exam and going on to university.
In an article published
in Scientific Reports, researchers affiliated with the University of São Paulo (USP) in Brazil describe experiments performed with mice that show how genetic factors can determine whether an individual is susceptible or resistant to leishmaniasis. According to the authors, the results will contribute to a better understanding of leishmaniasis in humans and help to clarify why only some of those individuals infected develop the disease.
Almost 35 years ago, scientists made the then-radical proposal that colossal hydrogen bombs called novae go through a very long-term life cycle after erupting, fading to obscurity for hundreds of thousands of years and then building back up to become full-fledged novae once more. A new study is the first to fully model the work and incorporate all of the feedback factors now known to control these systems, backing up the original prediction while bringing new details to light.
An analysis out of the University of Georgia details the relationship between consumer awareness and the attentiveness and care given to pollinator-friendly plant purchases.
Engineers and technicians at the National Institute of Standards and Technology (NIST) spent months meticulously recreating the long concrete floors supported by steel beams commonly found in high-rise office buildings, only to deliberately set the structures ablaze, destroying them in a fraction of the time it took to build them.
OAK BROOK, Ill. - Clinical data should be treated as a public good when it is used for secondary purposes, such as research or the development of AI algorithms, according to a special report published in the journal Radiology.
Using a recently developed fluorescent imaging technique, researchers in the United States have developed high-resolution maps of microbial communities on the human tongue. The images, presented March 24 in the journal Cell Reports, reveal that microbial biofilms on the surface of the tongue have a complex, highly structured spatial organization.
BOSTON (March 24, 2020, 11:00 a.m. EDT)--Despite consuming fewer sugar-sweetened beverages and more whole grains, most American children and adolescents still eat poorly - and sociodemographic disparities persist, according to an 18-year national study between 1999 and 2016 of U.S. children's dietary trends.
What The Study Did: Researchers looked at whether taking more steps and higher intensity stepping were associated with reduced risk of death in this observational study that included almost 4,900 adults (40 and over) who wore a device called an accelerometer to measure their step count and step intensity (steps/minute).
Authors: Pedro F. Saint-Maurice, Ph.D., of the National Cancer Institute in Rockville, Maryland, is the corresponding author.
A group of scientists from the Research Center of Neurology and Skoltech showed that human working memory can be tweaked using non-invasive magnetic stimulation of the brain. Also, they discovered that the effect of magnetic stimulation weakens as the brain works on a cognitive task under stimulation.
