Adolescents and young adults may be more susceptible to COVID-19 than previously believed, according to analysis of cases in six U.S. states experiencing surges.
Individuals' willingness to engage in COVID-19 control measures is associated with their trust in the government, other citizens, and in particular science, according to a new study published this week in the open-access journal PLOS ONE by Stefano Pagliaro of University of Chieti-Pescara, Italy, and colleagues.
Blood pressure measurements in children and adolescents should be taken from both arms after new research showed substantial differences could be seen depending on which arm was used.
The study, led by the Murdoch Children's Research Institute (MCRI) and published in the Journal of Hypertension, found even a small difference in blood pressure measurements between arms could lead to a wrong diagnosis.
Recently, Prof. ZHU Shu from University of Science and Technology of China (USTC) of CAS and Prof. Richard A. Flavell from Yale University were invited to publish a review article in Nature Reviews Gastroenterology and Hepatology. They systematically summarized the gastrointestinal manifestations in patients with COVID-19 and explored the possible mechanisms of intestinal symptoms caused by COVID-19 infection.
As countries around the world race to mitigate global warming by limiting carbon dioxide emissions, an unlikely source could be making climate goals harder to achieve without even deeper cuts in greenhouse gas production: reductions in air pollution.
New modeling experiments from Kyushu University in Japan of the long-term effects of reductions in pollutants known as sulfate aerosols predicts further increases in surface air temperature at current and increased carbon dioxide levels because of the loss of an overall cooling effect caused by the light-scattering particles.
The unpredictable nature of life during the coronavirus pandemic is particularly challenging for many people. Not everyone can cope equally well with the uncertainty and loss of control. Research has shown that while a large segment of the population turns out to be resilient in times of stress and potentially traumatic events, others are less robust and develop stress-related illnesses. Events that some people experience as draining seem to be a source of motivation and creativity for others.
In a study recently published in Nature Communications, scientists from The Novo Nordisk Foundation Center for Biosustainability (DTU) and Yale University have investigated how bacteria that are commonly found in sugarcane ethanol fermentation affect the industrial process. By closely studying the interactions between yeast and bacteria, it is suggested that the industry could improve both its total yield and the cost of the fermentation processes by paying more attention to the diversity of the microbial communities and choosing between good and bad bacteria.
Italian and Russian researchers confirmed the hypothesis that the self-maintaining order in eukaryotic cells (cells with nuclei) is a result of two spontaneous mechanisms' collaboration. Similar molecules gather into 'drops' on the membrane and then leave it as tiny vesicles enriched by the collected molecules. The paper with the research results was published in the journal Physical Review Letters.
Women of the ruling class may have played an important role in the governance of El Argar, a society which flourished in the southeast of the Iberian Peninsula between 2200 and 1550 BCE, and which in the last two centuries of its existence, developed into the first state organisation of the western Mediterranean.
Almost 60% of frontline health and social care workers (HSCWs) experienced a mental health disorder during the first COVID-19 lockdown, with many suffering "very high rates of distress", suggests a new study led by researchers at UCL and the University of Haifa, Israel.
Nearly 100 percent of the red snapper sampled in the Gulf of Mexico over a six-year period by University of South Florida (USF) marine scientists showed evidence of liver damage, according to a study reported in Aquatic Toxicology.
Game theory is known to be a useful tool in the study of Machine Learning (ML) and Artificial Intelligence (AI) Multi-Agent interactions.
One basic component of these ML and AI systems is the exploration-exploitation trade-off, a fundamental dilemma between taking a risk with new actions in the quest for more information about the environment (exploration) and repeatedly selecting actions that result in the current maximum reward or (exploitation).
Research published in Environmental Toxicology and Chemistry shows that the presence of polybrominated diphenyl ethers (PBDEs) in bald eagle populations is slowly declining. Bald eagles are apex predators that nest and, more importantly, feed along water bodies, making them excellent bioindicators of environmental contaminants that bioaccumulate up the aquatic food web. The findings are both good news for eagles and instructive for regulators tasked with managing surface water quality by setting protective levels for wildlife, as well as fish consumption advisories for humans.
Scientists at Tokyo Institute of Technology (Tokyo Tech) have uncovered mechanisms underlying the activation of the MRN complex-- the cell's DNA scissors. Using purified yeast proteins, they demonstrated that phosphorylation of Ctp1, a homolog of a tumor-suppressor protein, plays a key role in activating MRN complex's DNA clipping activity. Intriguingly, a short segment of yeast Ctp1 or its human counterpart could stimulate endonuclease activity of their respective MRN complexes, suggesting its conserved function across species.
BINGHAMTON, NY -- Star employees often get most of the credit when things go right, but also shoulder most of the blame when things go wrong, according to new research from Binghamton University, State University of New York.
The study explored the potential risks and rewards of collaborating with stars - individuals who have a reputation for exhibiting exceptional performance - and how individual performance factors into how much credit and blame is shared with collaborators.
