When their manhood is threatened, some men respond aggressively, but not all. New research from Duke University suggests who may be most triggered by such threats - younger men whose sense of masculinity depends heavily on other people's opinions.
A new modelling study has estimated that from 2000 to 2030 vaccination against 10 major pathogens - including measles, rotavirus, HPV and hepatitis B - will have prevented 69 million deaths in low-income and middle-income countries (LMICs).
For most of Earth's history, life was limited to the microscopic realm, with bacteria occupying nearly every possible niche.
An international team of researchers produced islands of amorphous, non-crystalline material inside a class of new metal alloys known as high-entropy alloys. This discovery opens the door to applications in everything from landing gears, to pipelines, to automobiles. The new materials could make these lighter, safer, and more energy efficient.
Beyond the ski slopes, one of the most iconic symbols of the Alps are the alpine flowers.
Recent research on the neutron-proton (np) reaction could help us understand the age of the Earth and build less expensive nuclear power plants. The np reaction plays a role in potassium-argon dating and in the removal of neutrons from nuclear reactor cores, leading to core shutdown. In recent studies, nuclear scientists used a new neutron source to show that np reaction rates occur in ways very different from scientists’ initial expectations.
Methane (CH4) is the second most important greenhouse gas after carbon dioxide (CO2).
Supercomputers funded by the National Science Foundation are being used to develop more reliable and efficient electric vehicles and other products by focusing on the batteries that power them.
New research from the University of Sheffield has found being overweight is an additional burden on brain health and it may exacerbate Alzheimer's disease.
Chronic stress can lead to or advance a number of diseases as the stress axis is continually activated. In a first, Prof. Alon Chen’s lab has revealed the entire stress axis, mapping it to the gene expression pattern of individual cells. The findings may lead to treatments for conditions such as metabolic syndrome, high blood pressure, and depression and anxiety.
Nearly nine out of 10 Americans say they enjoy sports at least a little, but heterosexual men more commonly identify as passionate sports fans, a new study suggests.
Counties that score worst on measures of poverty, economic inequality, housing, food access, family structure, transportation, insurance and disability had far more cases and deaths from coronavirus in the first months of the pandemic.
Large study publishing in JAMA Network Open shows Black and Hispanic children in hospital emergency departments are less likely to have imaging tests, such as X-rays or CT scans, ordered for them compared to White children. The authors attribute this disparity largely to overuse among Whites.
A Cornell-led collaboration has developed a noninvasive blood test that uses cell-free DNA to gauge the damage that COVID-19 inflicts on cells, tissues and organs, and could help aid in the development of new therapies.
New research suggests that for some cobras, the venom evolved additional complexity to deter potential enemies – possibly including Homo erectus, humans’ extinct close relative.
According to a new study, personality traits are associated with changes in alcohol use and problematic drinking, but these relationships may vary across the lifespan. The study explores alcohol consumption in the context of adult developmental stages. It suggests that changes in impulsivity and in the perceived rewards of alcohol are strongly related to changes in drinking behavior from ages 18-21, and to a lesser degree until at least age 35. Problematic drinking is known to be associated with impulsivity traits: a lack of planning (impulse control), sensation seeking, and the anticipated benefits from alcohol, such as sociability and making activities more enjoyable. Such traits evolve through adolescence and early adulthood. Understanding how shifting factors may elevate the risk to certain people at certain times potentially helps target interventions aimed at reducing heavy drinking and preventing alcohol use disorder (AUD). The study in Alcoholism: Clinical and Experimental Rese
Robotic-assisted knee replacement allows for optimal alignment and positioning of the knee implant, as well as optimal ligament balancing. This is critically important for the best outcome and long-term success of the surgery, according to Geoffrey Westrich, MD, at Hospital for Special Surgery. Such precision could potentially lead to a longer-lasting knee replacement.
In a new study, Scott Duxbury, Assistant Professor of Sociology at UNC, considers whether racial threat drove states to adopt punitive sentencing laws. His findings reveal that punitive sentencing laws, which have been implicated in racial disparity in punishment during mass incarceration, were adopted in response to large, rather than growing, black populations.
A new study by UC San Diego biologists has revealed insights on the intricate, adaptive mechanisms of a protective system employed by the cells of mammalian immune systems. These defenses have evolved to set a type of tripwire that produces an immune response against attack from viruses.
The AAVCOVID vaccine program, a novel gene-based vaccine strategy that utilizes an adeno-associated virus (AAV) vector, was granted an award for up to $2.1 million from the Bill & Melinda Gates Foundation. In data released in preprint, two AAVCOVID vaccine candidates led to robust neutralizing antibody responses in mouse and nonhuman primate models from only a single dose. The candidates were also shown to be safe and well-tolerated in both models.
