Preventing spread of SARS coronavirus-2 in humans
Viruses must enter cells of the human body to cause disease. Infection biologists from the German Primate Center, together with colleagues at Charité - Universitätsmedizin Berlin, have investigated how the novel coronavirus SARS-CoV-2 penetrates cells. They have identified a cellular enzyme that is essential for viral entry into lung cells: the protease TMPRSS2. A clinically proven drug...
Public health leaders call for coordinated communication response to COVID-19
On Thursday in the National Academy of Medicine's Perspectives, public health leaders including CUNY Graduate School of Public Health and Health Policy Distinguished Lecturer Scott Ratzan, MD called for informed and active public policy leadership to employ strategically coordinated health communication and outreach on COVID-19 and other emerging global health threats.
Research shows microplastics are damaging to coral ecosystems
Coral endosymbionts exposed to microplastics experience significant reduction in population size as well as cell size.
Researchers discover a new diet-associated gut-microbe metabolite linked to cardiovascular disease
Cleveland Clinic researchers have identified a gut microbe-generated byproduct -- phenylacetylglutamine (PAG) -- that is linked to development of cardiovascular disease, including heart attack, stroke and death. The study was published in Cell today.
Researchers discover a previously unappreciated neurotransmitter system in the brain
Within this system, the transmission of signals between neurons in the brain occurs via the trace amine-associated receptor 5 (TAAR5). The results of the study will allow the development of new types of drugs for depression, schizophrenia and anxiety disorders.
Researchers question reliability of common autistic personality test
Autistic personality questionnaire used by GPs and researchers is 'unreliable' say researchers from universities of Bath and Cardiff.
Rivers: how they contribute to better understand the Mediterranean Sea dynamics
A new study lead by the CMCC Foundation will provide key information to support and improve the operational ocean forecasts released by Copernicus, develop climate scenarios, and in the future support the design of nature-based solutions to improve environmental resilience and reduce hydro-meteorological risks in Europe. Insights and perspectives from a study on Ocean Modelling lead by the CMCC...
Satellite data boosts understanding of climate change's effects on kelp
Tapping into 35 years of satellite imagery, researchers have dramatically enlarged the database regarding how climate change is affecting kelps, near-shore seaweeds that provide food and shelter for fish and protect coastlines from wave damage.
Scientists create model to predict multipathogen epidemics
In one of the first studies of its kind, bioscientists from Rice University and the University of Michigan have shown how to use the interactions between pathogens in individual hosts to predict the severity of multipathogen epidemics.
Scientists develop free computer program to map blood flow 'landscape' in tumors
Johns Hopkins Medicine researchers have created a computer program for scientists at no charge that lets users readily quantify the structural and functional changes in the blood flow networks feeding tumors.
Scientists develop new method to distinguish freshly made transcripts from old transcripts
Researchers from the Hubrecht Institute (KNAW) developed a new method to assess how production and degradation of gene transcripts are regulated. In this study, published in Science on the 6th of March, they found that cells use distinct strategies to control the number of transcript copies, which is required for the cell to function properly.
Scientists monitored brains replaying memories in real time
In a study of epilepsy patients, researchers at the National Institutes of Health monitored the electrical activity of thousands of individual brain cells, called neurons, as patients took memory tests. They found that the firing patterns of the cells that occurred when patients learned a word pair were replayed fractions of a second before they successfully remembered the pair.
Scientists say it is time to save the Red Sea's coral reef
An international group of researchers led by Karine Kleinhaus, M.D., of the Stony Brook University School of Marine and Atmospheric Sciences (SoMAS), calls upon UNESCO to declare the Red Sea's 4,000 km of coral reef as a Marine World Heritage Site and recommends additional measures critical for the reef's survival. the study is published in Frontiers in Marine Sciences.
Self-driving car trajectory tracking gets closer to human-driver ideal
Have you taken an Uber ride and disagreed with the 'fastest' route that the GPS app suggested because you or the driver know a 'better' way? For society to truly embrace self-driving cars, the experience of passengers must feel just as comfortable as any trip with a human driver to get there. This is an extremely difficult computational challenge, but researchers are getting us a little bit...
Skoltech scientists break Google's quantum algorithm
In the near term, Google has devised new quantum enhanced algorithms that operate in the presence of realistic noise. The so called quantum approximate optimisation algorithm, or QAOA for short, is the cornerstone of a modern drive towards noise-tolerant quantum enhanced algorithm development. The all-Skoltech team led by Prof. Jacob Biamonte discovered and quantified what appears to be a...
Social isolation could cause physical inflammation
Social isolation could be associated with increased inflammation in the body new research from the University of Surrey and Brunel University London has found.
Social studies teachers link their political views to assessment of news sources
At a time when there's been a sharp uptick in partisan critiques of the credibility of the news media and growing concern among educators about student media literacy, a new study finds a strong connection between high school social studies teachers' political ideology and how credible they find various mainstream news outlets.
Solving a mystery in 126 dimensions
One of the fundamental mysteries of chemistry has been solved by Australian scientists - and the result may have implications for future designs of solar cells, organic light-emitting diodes and other next gen technologies.
Sphingotec's endothelial function biomarker bio-ADM® improves risk stratification of sepsis patients at ICUs
New study data show that monitoring blood levels of sphingotec's endothelial function biomarker bio-ADM® on top of guideline parameter lactate improves risk stratification of sepsis patients admitted to intensive care units.
Study finds music therapy helps stroke patients
New research has found that music therapy sessions have a positive effect on the neurorehabilitation of acute stroke patients, as well as their mood.
Study finds that Community Treatment Orders do not reduce hospital readmission rates or stays
CTOs are a legal order for compulsory community monitoring and treatment of people discharged from psychiatric hospitals and were introduced in the Mental Health Act amendment in 2007. This research finds they are associated with an increased risk of readmission as well as increased time spent in psychiatric hospitals.
Study: Organic molecules discovered by Curiosity Rover consistent with early life on Mars
Organic compounds called thiophenes are found on Earth in coal, crude oil and oddly enough, in white truffles, the mushroom beloved by epicureans and wild pigs. Thiophenes were also recently discovered on Mars, and Washington State University astrobiologist Dirk Schulze-Makuch thinks their presence would be consistent with the presence of early life on Mars. This study explores some of the...
Study: Tuberculosis bacteria trigger cough, facilitating spread
The bacteria that cause the deadly lung disease tuberculosis appear to facilitate their own spread by producing a molecule that triggers cough.
Superhydrophobic magnetic sponge to help purify water from oil products
TPU jointly with the University of Lille developed a new material capable of purifying water effectively from oil products. It is based on an ordinary household polyurethane sponge. It repels water, while effectively sorbing oil product molecules.
Terahertz radiation technique opens a new door for studying atomic behavior
Researchers from the Department of Energy's SLAC National Accelerator Laboratory have made a promising new advance for the lab's high-speed 'electron camera' that could allow them to 'film' tiny, ultrafast motions of protons and electrons in chemical reactions that have never been seen before.
