Most concussions occur because of force equal to 95 g's to the human body upon impact. G-force is a unit of force equal to the force exerted by gravity, we experience 1 g walking around. A typical person may reach about 5 g's (49 m/s2) during a roller coaster ride while the g-force experienced by military fighter pilots is nine. But a football player being hit receives 103, according to Head injury expert Kim Gorgens, a neuropsychologist at the University of Denver who specializies in brain injury.
People exposed to chemical warfare agents (CWAs) often incur chronic damage to their lungs, skin and eyes, for example. They also frequently succumb to depression, anxiety and suicidal thoughts. This is shown by research on survivors from the 1988 gas attacks against Kurdish Halabja in Iraq.
"The findings show that exposure to chemical warfare agents, especially sulfur mustard, results in lifelong physical and mental ill-health," says Faraidoun Moradi, a doctoral student of occupational and environmental medicine at Sahlgrenska Academy, University of Gothenburg, Sweden.
Universal college admission testing in the state of Virginia could increase the number of high school graduates with test scores competitive for admission at universities in the state by as much as 40 percent--and at the most selective institutions, nearly 20 percent--with larger increases for low-income students.
SAN ANTONIO -- June 25, 2019 -- A Southwest Research Institute-led team studied the orientation of distant solar system bodies to bolster the "streaming instability" theory of planet formation.
"One of the least understood steps in planet growth is the formation of planetesimals, bodies more than a kilometer across, which are just large enough to be held together by gravity," said SwRI scientist Dr. David Nesvorny, the lead author of the paper "Trans-Neptunian Binaries as Evidence for Planetesimal Formation by the Streaming Instability" published in Nature Astronomy.
People who care for their elderly parents outside of their full-time jobs -- and are unpaid for their help -- experience considerable disruption of their workplace routines. Many are not getting employer support because it is not offered or because they do not feel able to use it, even if it is available, according to a Baylor University researcher.
To solve one of the key obstacles in big-data science, KAUST researchers have created a framework for searching very large datasets that runs easily on different computing architectures. Their achievement allows researchers to concentrate on advancing the search engine, or query engine, itself rather than on painstakingly coding for specific computing platforms.
Bottom Line: Food insecurity is when you worry that your food will run out before you have enough money to buy more. This study used nationally representative data to examine the association between food insecurity and migraine in young U.S. adults because the economic and education transition of young adulthood may increase risk for food insecurity. The study included almost 14,800 young people (ages 24 to 32). Overall, 11% of young adults were food insecure, and migraine was more common among young adults who were food insecure.
Berkeley -- The rise of anti-immigration rhetoric and policies in the United States following the 2016 presidential election may be taking its toll on the health of California's Latinx youth, including those who are U.S. citizens, suggests a new study led by University of California, Berkeley, researchers.
A large-scale study from The University of Toledo of young African Americans who have attempted or died by suicide suggests there is a greater need for mental health services in urban school districts, and that we need to do a better job in convincing parents and caregivers to safely secure firearms and ammunition in the home.
Taking those measures, Dr. James Price said, could save lives.
High school students who take music courses score significantly better on math, science and English exams than their non-musical peers, according to a new study published in the Journal of Educational Psychology.
School administrators needing to trim budgets often look first to music courses, because the general belief is that students who devote time to music rather than math, science and English, will underperform in those disciplines.
Researchers from MIPT, Skoltech, the Joint Institute for High Temperatures of the Russian Academy of Sciences, and Lomonosov Moscow State University have offered a new approach to oil composition analysis. They used high temperature and pressure to dissolve oil in water and analyze its composition. The new method is compliant with the green chemistry principle as it makes it possible to avoid using environmentally hazardous solvents. The paper was published in the Analytical and Bioanalytical Chemistry journal.
Sleep disturbances and mental health challenges are putting close to half of America's firefighters at high risk of emotional fatigue and exhaustion, new research shows.
The research was conducted by Monash University in Australia in collaboration with Brigham and Women's Hospital in Boston, USA.
Of the 6,307 firefighters from 66 fire departments across the USA that took part in this cross-sectional study, 49% exhibited high levels of physical and emotional burnout in at least one area.
PHILADELPHIA--Many elderly patients with metastatic renal cell carcinoma (RCC)--who are often underrepresented in clinical trials to treat the kidney cancer--are seeing overall survival benefits from treatment with targeted therapies, according to a new study from Penn Medicine researchers published this month in JAMA Network Open.
A new study published in the journal Science finds that the world's marine fisheries form a single network, with over $10 billion worth of fish each year being caught in a country other than the one in which it spawned.
While fisheries are traditionally managed at the national level, the study reveals the degree to which each country's fishing economy relies on the health of its neighbors' spawning grounds, highlighting the need for greater international cooperation.
