Alcohol appears to have an immediate--or near-immediate--effect on heart rhythm, significantly increasing the chance that an episode of atrial fibrillation (AFib) will occur, according to new data presented at the American College of Cardiology's 70th Annual Scientific Session.
On Sept. 9, 2018, astronomers spotted a flash from a galaxy 860 million light years away. The source was a supermassive black hole about 50 million times the mass of the sun. Normally quiet, the gravitational giant suddenly awoke to devour a passing star in a rare instance known as a tidal disruption event. As the stellar debris fell toward the black hole, it released an enormous amount of energy in the form of light.
Indigenous peoples in Canada have higher rates of death and complications after surgery and lower rates of surgeries than other populations, found new research published in CMAJ (Canadian Medical Association Journal).
Whether it's plankton exposed to parasites or people exposed to pathogens, a host's initial immune response plays an integral role in determining whether infection occurs and to what degree it spreads within a population, new University of Colorado Boulder research suggests.
ATS 2021, New York, NY - A weighted "lottery" designed to increase access to the antiviral drug remdesivir during the May-July 2020 COVID-19 surge for those most affected by the coronavirus, including members of the Black, Latinx and indigenous communities, led to more equitable distribution of the badly needed medication, according to research presented at the ATS 2021 International Conference.
WINSTON-SALEM, N.C. - May 16, 2021 - Heart failure (HF) - when the heart can't pump enough blood and oxygen through the body - affects approximately 6.2 million adults in the United States and is the primary cause of hospitalization in the elderly. Unfortunately, older adults with heart failure often have poor outcomes resulting in reduced quality of life, high mortality and frequent rehospitalizations.
Despite many efforts to improve the prognosis in these patients, most previous studies testing a wide range of interventions were not successful.
The question of why we dream is a divisive topic within the scientific community: it's hard to prove concretely why dreams occur and the neuroscience field is saturated with hypotheses. Inspired by techniques used to train deep neural networks, Erik Hoel (@erikphoel), a research assistant professor of neuroscience at Tufts University, argues for a new theory of dreams: the overfitted brain hypothesis.
HOUSTON - (May 14, 2021) - Rice University bioengineers are fabricating and testing tunable electrospun scaffolds completely derived from decellularized skeletal muscle to promote the regeneration of injured skeletal muscle.
What The Study Did: This is a qualitative study that evaluates a crowdsourcing open call to gather community input for engaging the university community in COVID-19 safety strategies.

In research made possible when COVID-19 sidelined other research projects, scientists at Johns Hopkins Medicine meticulously counted brain cells in fruit flies and three species of mosquitos, revealing a number that would surprise many people outside the science world.
The insects' tiny brains, on average, have about 200,000 neurons and other cells, they say. By comparison, a human brain has 86 billion neurons, and a rodent brain contains about 12 billion. The figure probably represents a "floor" for the number needed to perform the bugs' complex behaviors.
Being treated fairly is important - but fairness alone isn't enough to make people feel valued in a workplace or other groups, new research suggests.
Researchers found that "distinctive treatment" - where a person's talents and qualities are recognised - provides this sense of value while also reinforcing their sense of inclusion. It also promotes mental health.
The findings suggest there is no conflict between "fitting in" and "standing out" in groups - in fact, they complement each other.
Tokyo, Japan - Oxygen is crucial to many forms of life. Its delivery to the organs and tissues of the body through the process of respiration is vital for most biological processes. Now, researchers at Tokyo Medical and Dental University (TMDU) have shown that oxygen can be delivered through the wall of the intestine to compensate for the reduced availability of oxygen within the body that occurs in lung diseases that cause respiratory failure.
Yoga and breathing exercises have a positive effect on children with attention deficit hyperactivity disorder (ADHD). After special classes, children improve their attention, decrease hyperactivity, they do not get tired longer, they can engage in complex activities longer. This is the conclusion reached by psychologists at Ural Federal University who studied the effect of exercise on functions associated with voluntary regulation and control in 16 children with ADHD aged six to seven years. The results of the study are published in the journal Biological Psychiatry.
The COVID-19 lockdown was a catalyst for many older people to embrace technology, reconnect with friends and build new relationships with neighbours, according to University of Stirling research.
Understanding the coping mechanisms adopted by some over 60s during the pandemic will play a key role in developing interventions to help tackle loneliness, isolation and wellbeing in the future.
