Psychologists have long found that people behave differently than when they learn of peers' actions. A new study by computer scientists found that when individuals in an experiment about autonomous vehicles were informed that their peers were more likely to sacrifice their own safety to program their vehicle to hit a wall rather than hit pedestrians who were at risk, the percentage of individuals willing to sacrifice their own safety increased by approximately two-thirds.
The COVID-19 virus holds some mysteries. Scientists remain in the dark on aspects of how it fuses and enters the host cell; how it assembles itself; and how it buds off the host cell.
Computational modeling combined with experimental data provides insights into these behaviors. But modeling over meaningful timescales of the pandemic-causing SARS-CoV-2 virus has so far been limited to just its pieces like the spike protein, a target for the current round of vaccines.
Timothy Callaghan, PhD, and Alva Ferdinand, DrPH, JD, from the Southwest Rural Health Research Center at Texas A&M University School of Public Health, joined colleagues in the first national study of how often people in urban and rural areas in the United States follow COVID-19 guidelines.
DETROIT (February 25, 2021) - Researchers at Henry Ford Health System, as part of a national asthma collaborative, have identified a gene variant associated with childhood asthma that underscores the importance of including diverse patient populations in research studies.
The study is published in the print version of the American Journal of Respiratory and Critical Care Medicine.
Preterm labor comprises 12.7% of all pregnancies. Although the overall rate of pregnancy is decreasing, the occurrence of premature birth due to preterm labor in south korea has been increasing over the past 7 years. Not only is preterm birth accountable for about a half of all neonatal mortality cases, the neurological deficits in surviving premature infants often lead to problems later in life, such as developmental disorders and respiratory complications.
The total amount of data generated worldwide is expected to reach 175 ZB (Zettabytes; 1 ZB equals 1 billion Terabytes) by 2025. If 175 ZB were stored on Blu-ray disks, the disk stack would be 23 times the distance to the Moon. We face the urgent need to develop storage technologies that can accommodate this enormous amount of data.
ROCKVILLE, MD - Scientists are still a long way from being able to treat Alzheimer's Disease, in part because the protein aggregates that can become brain plaques, a hallmark of the disease, are hard to study. The plaques are caused by the amyloid beta protein, which gets misshapen and tangled in the brain. To study these protein aggregates in tissue samples, researchers often have to use techniques that can further disrupt them, making it difficult to figure out what's going on.
Our use of social media, specifically our efforts to maximize "likes," follows a pattern of "reward learning," concludes a new study by an international team of scientists. Its findings, which appear in the journal Nature Communications, reveal parallels with the behavior of animals, such as rats, in seeking food rewards.
The koala retrovirus (KoRV) is a virus which, like other retroviruses such as HIV, inserts itself into the DNA of an infected cell. At some point in the past 50,000 years, KoRV has infected the egg or sperm cells of koalas, leading to offspring that carry the retrovirus in every cell in their body. The entire koala population of Queensland and New South Wales in Australia now carry copies of KoRV in their genome.
PHILADELPHIA-- Even though the use of rhythm control strategies for treating Paroxysmal Atrial Fibrillation (AF), a common abnormal heart rhythm, have increased overall in the United States, patients from racial and ethnic minority groups and those with lower income were less likely to receive rhythm control treatment - often the preferred treatment - according to new
When a muscle grows, because its owner is still growing too or has started exercising regularly, some of the stem cells in this muscle develop into new muscle cells. The same thing happens when an injured muscle starts to heal. At the same time, however, the muscle stem cells must produce further stem cells - i.e., renew themselves - as their supply would otherwise be depleted very quickly. This requires that the cells involved in muscle growth communicate with each other.
Muscle growth is regulated by the Notch signaling pathway
New York, NY (February 26, 2020) - Molecules called microRNAs (miRNAs) that are measurable in urine have been identified by researchers at Mount Sinai as predictors of both heart and kidney health in children without disease. The epidemiological study of Mexican children was published in February in the journal Epigenomics.
Who would have thought that a small basic compound like vitamin B6 in the banana or fish you had this morning may be key to your body's robust response against COVID-19?
Living in a group has clear benefits. As a member of a societal group, one can share resources with the others, seek protection from predators, and forage in an efficient manner.
The centre is part of the German Federal Institute for Risk Assessment (BfR). With the help of microscopy and artificial intelligence, the "E-Morph" test reliably identifies substances that can have oestrogen-like or even opposing effects, according to the research team's report in the specialist journal "Environment International". "E-Morph is a milestone on the way to, one day, replacing animal experiments currently required to detect hormone-like effects," says BfR President Prof. Dr. Dr. Andreas Hensel.
