When it comes to children, it is becoming clear that COVID-19 impacts them more than was initially realized. Yet there is relatively little information about SARS-CoV-2, the virus that causes the disease, in pediatric populations. Scientists at Children's Hospital Los Angeles have just published the largest pediatric COVID-19 study to date, suggesting, for the first time, a possible link between specific viral mutations and severity of the disease.
OAK BROOK, Ill. - Women who experience food or housing insecurity may be at risk for undiagnosed breast cancer due to lapses in follow-up appointments, according to research being presented at the annual meeting of the Radiological Society of North America (RSNA).
The Gerontological Society of America's highly cited, peer-reviewed journals are continuing to publish scientific articles on COVID-19, and all are free to access. The following were published between October 26 and November 13:
In high school textbooks, human chromosomes are pictured as wonky Xs like two hotdogs jammed together. But those images are far from accurate. "For 90 percent of the time," said Jun-Han Su, "chromosomes don't exist like that."
Experts trained a computer to tell which skin cancer patients may benefit from drugs that keep tumors from shutting down the immune system's attack on them, a new study finds.
Air pollution experts from the University of Surrey have found that green infrastructure (GI), such as trees, can help reduce temperatures in many of Europe's cities and towns.
An urban heat island is an urban area that is significantly warmer than its surrounding rural areas. The temperature difference is typically larger at night than during the day.
With the UK government pledging to build 300,000 new homes every year, it is feared that many of the country's towns and cities will experience an increase in temperature brought about by more vehicles and building activity.
Children in a Melbourne family developed a COVID-19 immune response after chronic exposure to the SARS-CoV-2 virus from their parents, a new case report has found.
The research, led by the Murdoch Children's Research Institute (MCRI) and published in
Nature Communications, showed that despite close contact with symptomatic infected parents, including one child sharing the parents' bed, the children repeatedly tested negative for COVID-19 and displayed no or minor symptoms.
Analysis by national consortium, OUTBREAK, highlights how urinary tract infections (UTIs) are becoming more persistent and harder to treat, resulting in more people being admitted to hospital where they require longer stays and more costly medicines.
OUTBREAK managing director Assoc. Prof. Branwen Morgan said drug-resistant UTIs were the canary in the coal mine for a growing number of antibiotic-resistant germs spreading in our community, animals and environment.
Scientists have discovered an extremely rare species of cymothoid from the mouth of a museum specimen of a deep-sea shark caught from the East China Sea, suggesting its wide distribution around the globe.
Cymothoids are a family of isopods (a type of crustacean) that are ectoparasites of fish. Some species in this family are also known as tongue-biter or tongue-eating louse (e.g., Cymothoa exigua).
Materials consisting of inorganic and organic components can combine the best of two worlds: under certain circumstances, the so-called MOFs - short for metal-organic frameworks - are structured in the same order as crystals and are at the same time porous and deformable. This opens up the prospect of intelligent materials for energy-saving technical applications. However, so far only a few flexible MOFs have been identified.
New measurements reveal a surprising increase in the amount of dense water sinking near Antarctica, following 50 years of decline.
Dense water formed near Antarctica, known as Antarctic Bottom Water, supplies oxygen to the deep ocean. Bottom water also forms part of the global network of ocean currents that influences climate by storing heat and carbon dioxide in the ocean. Changes in bottom water formation can therefore impact global climate and deep ocean ecosystems.
Long-term variability in the 'abundance' of a macro-organism could provide fundamental information for evaluating its evolution, its responses to climate changes and human impact, enabling management and preservation strategies. Biological monitoring in aquatic systems has provided evidence of long-term variability in the abundance of macro-organisms. However, almost all such records span less than a century; there are none which span centuries or more.
Nowadays, cannabidiol is a star component, not only in the world of cosmetics, but also in pharmaceutics and nutrition due to its antioxidant properties and its therapeutical potential. It is a natural molecule that comes from medicinal cannabis and that, despite being derived from it, is not a psychoactive compound, meaning that it has no effect upon the nervous system.
Rechargeable lithium-ion batteries (LIBs) are considered the best hope for next-generation battery technology, thanks to their long-life cycle, high specific power and energy density. However, they have not met the ever-increasing demands of emerging technologies such as electric vehicles. Li-Se battery technology is increasingly considered a real alternative to LIBs because of its high theoretical volume capacity and much higher conductivity.
(Boston)--Researchers from Boston University School of Medicine (BUSM) have identified that a peptide, pituitary adenylate cyclase-activating mediator of compulsive consumption of alcohol. In addition, they have discovered that this protein acts in an area of the brain called the Bed Nucleus of the Stria Terminalis, or BNST, a region involved in fear, anxiety and stress responses, to exert these effects.
