According to Carlos García Meca and Andrés Macho Ortiz, researchers at NTC-UPV, this new symmetry allows the conservation of the linear moment between dramatically different physical systems. This paves the way to designing pioneering optical, acoustic and elastic devices, including invisible omnidirectional, polarization-independent materials, ultra-compact frequency shifters, isolators and pulse-shape transformers.
As the COVID-19 pandemic enters its third month, businesses in the United States are marketing unlicensed and unproven stem-cell-based "therapies" and exosome products that claim to prevent or treat the disease. In Cell Stem Cell on May 5, bioethicist Leigh Turner describes how these companies are "seizing the pandemic as an opportunity to profit from hope and desperation."
A new study has found an association between low average levels of vitamin D and high numbers of COVID-19 cases and mortality rates across 20 European countries.
The research, led by Dr Lee Smith of Anglia Ruskin University (ARU) and Mr Petre Cristian Ilie, lead urologist of Queen Elizabeth Hospital King's Lynn NHS Foundation Trust, is published in the journal Aging Clinical and Experimental Research.
Plastic may be an indispensable part of our daily lives, but its robustness and abundance have led to its overuse, putting a huge burden on the environment. Large emissions of plastic waste result in its accumulation in water bodies: in fact, recent studies have estimated about 0.27 million tons of plastic floating in the world's oceans. Because plastic does not decompose in water, it is a serious hazard for the marine life. Thus, to prevent plastic pollution, it is crucial to understand exactly how plastic is emitted into the oceans.
As the world economy is falling into one of the biggest contractions of the last decades, a new study of economic recession patterns finds that the likelihood of a downturn was high even before the onset of the Coronavirus crisis.
Current knowledge about the role of aerosols in the transmission of SARS-CoV-2 warrants urgent attention. Current guidance and public health information has slowly shifted focus towards aerosols as a transmission pathway - predominantly associated with breathing and talking by asymptomatic individuals. Providing guidelines for sufficient inhalation protection will be important in curbing the spread of COVID-19.
Tel Aviv University (TAU) researchers have developed a safe and accurate 3D imaging method to identify sperm cells moving at a high speed.
The research, a study of which was published in Science Advances on April 10, was led by Prof. Natan Shaked of the Department of Biomedical Engineering at TAU's Faculty of Engineering together with TAU doctoral student Gili Dardikman-Yoffe.
Washington - (May 4, 2020) - The first ever set of specific recommendations to support transgender autistic young people was co-created by these youth and their families working hand-in-hand with clinical experts. The resulting model offers clinicians a set of concrete ways to provide this unique population the support they need.
CHAMPAIGN, Ill. -- When tested in brain cells and in a mouse model of Alzheimer's disease, a new compound significantly reduced the number of amyloid plaques in the brain, lessened brain inflammation and diminished other molecular markers of the disease.
The researchers who developed the compound report their findings in the journal ACS Chemical Neuroscience.
A small study funded by the National Institutes of Health suggests that sleep problems among children who have a sibling with autism spectrum disorder (ASD) may further raise the likelihood of an ASD diagnosis, compared to at-risk children who do not have difficulty sleeping. Previous research has shown that young children who have a sibling with ASD are at a higher risk for also being diagnosed with the condition. The study appears in The American Journal of Psychiatry.
The UK government made key failings in their strategic preparations and emergency response to coronavirus and this, in turn, undermined the NHS's ability to cope with the crisis.
These are the findings recently published in a research paper for the Journal of Risk Research by academics from Cass Business School, Glasgow Caledonian University, Vlerick Business School, and Nottingham University Business School.
While attention remains focused on the number of COVID-19 deaths and new cases, a separate statistic - the number of recovered patients - may be equally important to the goal of minimizing the pandemic's infection rate as shelter-in-place orders are lifted.
To keep patients and health-care providers safe from COVID-19, while providing urgent treatment to stroke patients, extra precautions must be taken, according to new guidelines published in the journal Stroke.
The guidelines were established by the Society of Vascular & Interventional Neurology (SVIN).
UCLA professor of neurology Dr. David Liebeskind, who is president of SVIN and director of the UCLA Stroke Center, expressed concern that fear of COVID-19 may make patients hesitate to seek treatment in the event of a possible stroke.
MAYWOOD, IL-Broad modifications to current standards for treating acute stroke patients during the COVID-19 pandemic may be needed to preserve health care resources, limit disease spread and ensure optimal care, according to a Loyola Medicine neurologist.
The COVID-19 pandemic has revealed major deficiencies and inequities in the U.S. healthcare system, shining a spotlight on improvements that must be made to steel the country for future disasters, argues Maia Dorsett in an Editorial. "US healthcare is incentivized to react to sickness rather than proactively focus on health maintenance," Dorsett writes.
