As the pandemic persists, COVID-19 has claimed more than 200,000 lives in the United States and damaged the public health system and economy. In a study published on September 21 in the journal The Innovation, researchers at Emory University found that long-term exposure to urban air pollution may have made COVID-19 more deadly.
DALLAS, Oct. 7, 2020 -- Feeling optimistic, that you have a sense of purpose in life and that you are in control of your environment - characteristics of psychosocial resilience - are associated with having better cardiovascular health among Black adults, independent of neighborhood context, according to a study published today in Circulation: Cardiovascular Quality and Outcomes, an American Heart Association journal.
The number of proteins in the human body, collectively known as the proteome, is vast. Somewhere between 80,000 and 400,000 proteins circulate in our cells, tissues and organs, carrying out a broad range of duties essential for life. When proteins go awry, they are responsible for a myriad of serious diseases.
Negative feelings resulting from perceived broken promises from employers within UK police forces are a major cause of workplace stress, according to new research at the University of Birmingham.
In a study of police officers, researchers from the University's School of Psychology found that employees who perceive a violation of their psychological contract - the negative emotional reactions in response to perceived broken promises at work - are at greater risk of job-related stress, anxiety and depression.
Scientists have made significant progress in understanding the sources of radiation events that could impact human space-flight operations. Relativistic Electron Precipitation (REP) events are instances when high energy electrons move through areas of space at significant fractions of the speed of light. These REP events may pose challenges to human spaceflight, specifically during extravehicular activity (EVA).
"Eat your spinach," is a common refrain from many people's childhoods. Spinach, the hearty, green vegetable chock full of nutrients, doesn't just provide energy in humans. It also has potential to help power fuel cells, according to a new paper by researchers in AU's Department of Chemistry.
LOS ALAMOS, N.M., October 5, 2020--A new algorithm that fast forwards simulations could bring greater use ability to current and near-term quantum computers, opening the way for applications to run past strict time limits that hamper many quantum calculations.
A major study of women with ductal carcinoma in situ (DCIS) - a breast condition that can become invasive cancer - has shown that surgery to remove the tissue followed by radiotherapy offers better protection compared to surgery alone.
The study, presented at the 12th European Breast Cancer Conference, followed patients for up to 27 years. Although it shows that the benefit of radiotherapy and surgery over surgery alone persists, it also suggests that this benefit reduces over time.
Researchers at Karolinska Institutet in Sweden have identified a protein in the brain that is important both for the function of the mood-regulating substance serotonin and for the release of stress hormones, at least in mice. The findings, which are published in the journal Molecular Psychiatry, may have implications for the development of new drugs for depression and anxiety.
Events at birth may affect the microbes living in a baby's gut during the first few months of life, leading to a higher risk of childhood obesity and allergies, according to a new study published in the journal Gastroenterology.
Experts working in the field of vaccine development tend to believe that an effective vaccine is not likely to be available for the general public before the fall of 2021. In a paper published this week in the Journal of General Internal Medicine, a McGill-led team published the results of a recent survey of 28 experts working in vaccinology.
The survey was carried out in late June 2020. The majority of those surveyed were mostly Canadian or American academics with an average of 25 years of experience working in the field.
A new study published in the journal Critical Care Explorations shows for the first time that part of the stress response in people and animals involves increasing the levels of a naturally circulating element in blood.
The discovery demonstrates a biological mechanism that rapidly responds to severe physiologic stress and potentially serves to protect us from further damage due to life-threatening conditions.
The content of the nightmares of nearly a thousand individuals during the coronavirus pandemic were analysed in a study published in the Frontiers in Psychology journal. The study found that the pandemic had affected more than half of the bad dreams reported.
A joint international research team from POSTECH of South Korea, Raytheon BBN Technologies, Harvard University, and Massachusetts Institute of Technology in the U.S., Barcelona Institute of Science and Technology in Spain, and the National Institute for Materials Science in Japan have together developed ultrasensitive sensors that can detect microwaves with the highest theoretically possible sensitivity.
A new study looking at incentives to reduce globally harmful peatland fires suggests that fear of enforcement and public health concerns influence behaviour more than the promise of financial rewards.
The findings come as wildfires devastate the US West Coast and Russian Arctic, and fire season begins in Australia, Indonesia and Brazil.
