Culture
Social insects like honeybees and hornets evolved from solitary bees and wasps, respectively. A common trait of many social insects is age-specific behavior: when they emerge from the pupa, workers typically specialize in around-the-clock tasks inside the darkness of the nest, starting with brood care. But they gradually shift towards more cyclic tasks away from center of the nest as they get older -- culminating in foraging outside, exclusively in daylight, towards the end of their life.
TALLAHASSEE, Fla. - Whether it is ants forming a trail or individuals crossing the street, the exchange of information is key in making everyday decisions. But new Florida State University research shows that the group decision-making process may work best when members process information a bit differently.
The discovery of a potential “Achilles heel” in Nef, the protein that is crucial to HIV virulence and its capacity to trigger AIDS, paves the way for the development of a new class of drugs against the virus. Researchers have succeeded in demonstrating a structure that binds this protein to another called AP-2 and regulates endocytosis, the process by which cells take in substances such as nutrients or pathogens by engulfing them in a vesicle.
URBANA, Ill. - Climate change and a growing world population require efficient use of natural resources. Water is a crucial component in food production, and water management strategies are needed to support worldwide changes in food consumption and dietary patterns.
Agricultural production and food manufacturing account for a third of water usage in the U.S. Water use fluctuates with weather patterns but is also affected by shifts in production technology, supply-chain linkages, and domestic and foreign consumer demand.
Trifarotene is a drug for the external treatment of acne vulgaris of the face and trunk. It is suitable for affected people with many comedones, papules and pustules, i.e. with moderate acne for which systemic therapy is not yet an option.
The stress and anxiety experienced by the general population during Israel's first lockdown brought about a significant rise in orofacial and jaw pain, as well as jaw-clenching in the daytime and teeth-grinding at night, according to a new study from Tel Aviv University (TAU).
The research also found that women suffered more from these symptoms more than men, and that 35- to 55-year-olds suffered most.
The agricultural industry relies heavily on chemical fungicides to protect crops. Many of these products have a detrimental effect on human and animal health. As a result, some of the most effective fungicides are considered to be banned in a number of geographies, especially in Europe.
During the height of the pandemic, researchers at Children's National Hospital discovered that as many as one half of children diagnosed with multisystem inflammatory disease in children (MIS-C) at the hospital developed cardiac complications including coronary artery abnormalities, even when diagnosed and treated promptly.
New research from the University of Southern California measured the use of Medicaid's annual wellness visits and the receipt of structured cognitive assessments among Medicaid beneficiaries.
DALLAS, Nov. 14, 2020 -- The use of the more potent antiplatelet medication ticagrelor was not superior to clopidogrel in the reduction of the rate of heart attack or severe complications among people undergoing an elective procedure to open a blocked artery, according to late-breaking research presented today at the American Heart Association's Scientific Sessions 2020.
DALLAS, Nov. 14, 2020 -- The primary results from the RIVER Trial, Rivaroxaban for Valvular Heart disease and Atrial Fibrillation, show that rivaroxaban is comparable to warfarin, which is currently the standard of care anticoagulant prescribed for patients with bioprosthetic mitral valves, according to late-breaking research presented today at the American Heart Association's Scientific Sessions 2020.
DALLAS, Nov. 15, 2020 -- A daily dose of omega-3 fatty acids did not reduce the risk of cardiac events, including secondary heart attack, stroke, bypass surgery or death, among elderly people who had survived a recent heart attack, according to late-breaking research presented today at the American Heart Association's Scientific Sessions 2020.
The brain encodes information collected by our senses. However, to perceive our environment and to constructively interact with it, these sensory signals need to be interpreted in the context of our previous experiences and current aims. In the latest issue of Science, a team of scientists led by Dr. Johannes Letzkus, Research Group Leader at the Max Planck Institute for Brain Research, has identified a key source of this experience-dependent top-down information.
Arlington, Va. (November 16, 2020) -- A variety of ticks that carry the bacteria causing the deadly disease Rocky Mountain spotted fever (RMSF) are more than twice as likely to shift their feeding preference from dogs to humans when temperatures rise, a sign that climate change could expand and intensify human disease risks, according to a new study presented today at the Annual Meeting of the American Society of Tropical Medicine and Hygiene (ASTMH).
DALLAS, November 16, 2020 -- Adults with the healthiest sleep patterns had a 42% lower risk of heart failure regardless of other risk factors compared to adults with unhealthy sleep patterns, according to new research published today in the American Heart Association's flagship journal Circulation. Healthy sleep patterns are rising in the morning, sleeping 7-8 hours a day and having no frequent insomnia, snoring or excessive daytime sleepiness.
