Cocaine addiction is a chronic disorder with a high rate of relapse for which no effective treatment is currently available. Scientists from the Institut Pasteur, the CNRS, Inserm and the Paris Public Hospital Network (AP-HP) recently demonstrated that two gene mutations involved in the conformation of nicotinic receptors in the brain appear to play a role in various aspects of cocaine addiction. The results of the study were published in Progress in Neurobiology.
Laboratory tests of surgical and N95 masks by researchers at the University of California, Davis, show that they do cut down the amount of aerosolized particles emitted during breathing, talking and coughing. Tests of homemade cloth face coverings, however, show that the fabric itself releases a large amount of fibers into the air, underscoring the importance of washing them. The work is published Sept. 24 in Scientific Reports.
WASHINGTON -- The anxiety, stress and worry brought on by COVID-19 is not limited to daytime hours. The pandemic is affecting our dreams as well, infusing more anxiety and negative emotions into dreams and spurring dreams about the virus itself, particularly among women, according to research published by the American Psychological Association.
In her ongoing research about Americans' responses to the COVID-19 pandemic, Northern Arizona University anthropology professor Lisa Hardy and her collaborators have talked to dozens of people. A couple of them stand out to the researchers.
Researchers have identified two antibodies that protect mice against lethal infections of influenza B virus, report scientists at Washington University School of Medicine in St. Louis and Icahn School of Medicine at Mount Sinai. Together with an antibody that targets the other major kind of influenza viruses that infect people -- influenza A -- these antibodies potentially could form the basis of a broad-spectrum flu drug that could treat almost all flu cases.
The findings are published Sep. 24 in the journal Immunity.
Philadelphia, September 24, 2020 - Building upon years of research, a new study from Children's Hospital of Philadelphia (CHOP) has demonstrated how a specific assessment of the eye could someday help properly diagnosis and monitor concussions. The findings were published today in JAMA Ophthalmology.
Ka-thump. Ka-thump. Ka-thump. Though we barely notice it most of the time, the steady beating of a human heart is an amazingly complex performance. Like an orchestra, thousands of cells have to master their individual performances as well as work together.
Scientists have created a detailed cellular and molecular map of the healthy human heart to understand how this vital organ functions and to shed light on what goes awry in cardiovascular disease.
The work, published in Nature Sept. 24 was led by investigators at Harvard Medical School, Brigham and Women's Hospital, the Wellcome Sanger Institute, Max Delbrück Center for Molecular Medicine (MDC) in Germany, Imperial College London and their global collaborators.
Being held by a parent with skin-to-skin contact reduces how strongly a newborn baby's brain responds to a painful medical jab, finds a new study led by researchers at UCL and York University, Canada.
The scientists report in the European Journal of Pain that there was more activity in the brains of newborn babies in reaction to the pain when a parent was holding them through clothing, than without clothing.
Researchers at the German Center for Neurodegenerative Diseases (DZNE) and Charité - Universitätsmedizin Berlin have identified highly effective antibodies against the coronavirus SARS-CoV-2 and are now pursuing the development of a passive vaccination. In this process, they have also discovered that some SARS-CoV-2 antibodies bind to tissue samples from various organs, which could potentially trigger undesired side effects. They report their findings in the scientific journal "Cell".
Small particles can have an angular momentum that points in a certain direction - the spin. This spin can be manipulated by a magnetic field. This principle, for example, is the basic idea behind magnetic resonance imaging as used in hospitals. An international research team has now discovered a surprising effect in a system that is particularly well suited for processing quantum information: the spins of phosphorus atoms in a piece of silicon, coupled to a microwave resonator.
Researchers at The University of Texas at Dallas have examined how manufacturers are -- or aren't -- pivoting successfully in response to major manufacturing disruptions as a consequence of the COVID-19 pandemic.
In a study published July 27 in IEEE Engineering Management Review, two faculty members from the Naveen Jindal School of Management found that manufacturing response to the disruption has been largely reactive and uncoordinated, and many firms' crisis communication plans do not include managing an infectious-disease outbreak.
September 24, 2020 - Nearly all women have breasts that are slightly different from each other. However, some women have more marked differences in the size, shape, or position of the breasts even after development is complete - leading to negative effects on emotional well-being and self-image.
In mid-April 2020, the national unemployment rate reached 14.7 percent - the highest since the Great Depression. Forty-one million American workers filed for unemployment between February and May of 2020.
