DURHAM, N.C. -- 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.
"Our results suggest that the more social pressure a man feels to be masculine, the more aggressive he may be," said Adam Stanaland, a Ph.D. candidate in psychology and public policy at Duke and the study's lead author.
Tiny molecular forces at the surface of water droplets can play a big role in laser output emissions. As the most fundamental matrix of life, water drives numerous essential biological activities, through interactions with biomolecules and organisms. Studying the mechanical effects of water-involved interactions contributes to the understanding of biochemical processes.
BOSTON-Boston Medical Center has released a study that shows post overdose outreach programs in Massachusetts have expanded across the state, as 44 percent of municipalities reported having such programs available - a majority established since 2015 - to reduce risks for those who survive an overdose. The results are published online in the February 2021 issue of Drug and Alcohol Dependence.
Laser-induced breakdown spectroscopy (LIBS) is a rapid chemical analysis tool. A powerful laser pulse is focused on a sample to create a microplasma. The elemental or molecular emission spectra from that microplasma can be used to determine the elemental composition of the sample.
The study of warm dense matter helps us understand what is going on inside giant planets, brown dwarfs, and neutron stars. However, this state of matter, which exhibits properties of both solids and plasmas, does not occur naturally on Earth. It can be produced artificially in the lab using large X-ray experiments, albeit only at a small scale and for short periods of time. Theoretical and numerical models are essential to evaluate these experiments, which are impossible to interpret without formulas, algorithms, and simulations.
With a powerful enough light, you can see things that people once thought would be impossible. Large-scale light source facilities generate that powerful light, and scientists use it to create more durable materials, build more efficient batteries and computers, and learn more about the natural world.
Attempts to identify the genetic causes of neuropsychiatric diseases such as post-traumatic stress disorder (PTSD) through large-scale genome-wide analyses have yielded thousands of potential links. The challenge is further complicated by the wide range of symptoms exhibited by those who have PTSD. For instance, does extreme arousal, anger, or irritation experienced by some have the same genetic basis as the tendency to re-experience traumatic events, another symptom of the disorder?
Washington, DC - January 28, 2021 - Self swabs and caregiver swabs are effective at detecting multiple pathogens and are just as accurate as those taken by healthcare workers, according to a team of Australian researchers. The research appears in the Journal of Clinical Microbiology, a publication of the American Society for Microbiology.
Although loggerhead sea turtles return to the same beach where they hatched to lay their eggs, a new study by a USF professor finds individual females lay numerous clutches of eggs in locations miles apart from each other to increase the chance that some of their offspring will survive.
A study published in the journal "Scientific Reports" found that some females lay as many as six clutches as far as six miles apart during the same breeding season.
Maybe space is tight in your home and you share a remote office with your spouse.
Or your partner asks you to step away from work to watch the children because they have an important call to jump on. Then you may wonder, 'Well, what makes his/her job more important than mine!'
There have been no shortage of conflicts arising from the era of COVID-19, and that includes the challenges at home between married couples.
Washington and Chicago, January 28, 2021--The American Educational Research Association (AERA) and the Spencer Foundation have released a report, Voices from the Field: The Impact of COVID-19 on Early Career Scholars and Doctoral Students, that shares findings from focus groups conducted in spring 2020. The report, available on the AERA and Spencer websites, is part of an ongoing initiative by the two organizations to assess the pressing needs facing scholars and doctoral students during the pandemic and ways to address these needs.
After analyzing the genomes of more than one-quarter of a million military veterans, a team of scientists, led by researchers at University of California San Diego, Veterans Affairs San Diego Healthcare System (VASDHS), Yale University and West Haven VA, have identified 18 specific, fixed positions on chromosomes (known as loci) that appear associated with post-traumatic stress disorder (PTSD).
HOUSTON - (Jan. 28, 2021) - Like a wrench that gums up the gears, a common anesthetic keeps the motor proteins in your cells from making their rounds.
This is not necessarily a bad thing, but how it works has been a mystery until now.
Researchers at Rice's Center for Theoretical Biological Physics (CTBP) detail the mechanism that allows propofol -- the general anesthetic injected to knock you out before surgery -- to halt the movement of kinesin proteins that deliver cargoes along microtubules to the far reaches of cells.
WACO, Texas (Jan. 28, 2021) - An organization that projects an ethical face but whose managers fail to respond to internal ethical situations sends mixed messages to its employees, which can lead to a lack of employees' moral courage and an increase in unethical behavior, according to a study led by a Baylor University researcher.
The emergence of SARS-CoV-2 virus variants that are adding twists in the battle against COVID-19 highlight the need for better genomic monitoring of the virus, says Katia Koelle, associate professor of biology at Emory University.
