Bottom Line: The current immigration policy environment in America appears to be associated with reported adverse mental health outcomes among U.S.-born children of Latinx immigrants. Data were used from a group of 397 U.S.-born adolescents with at least one immigrant parent from a long-term study of Mexican farmworker families in the Salinas Valley of California.
WASHINGTON -- High schoolers who take music courses score significantly better on exams in certain other subjects, including math and science, than their non-musical peers, according to a study published by the American Psychological Association.
Parent-child discussions about sexual health and sexual identity are complicated, particularly with a male teen who identifies as gay, bisexual, or queer (GBQ). New research from the University of Pennsylvania shows that even as parents become savvier in these conversations, departing from gender stereotypes and embracing more accepting attitudes, factors beyond the home will still affect the message parents convey and their child hears.
TROY, N.Y. -- Increased solar radiation penetrating through the damaged ozone layer is interacting with the changing climate, and the consequences are rippling through the Earth's natural systems, effecting everything from weather to the health and abundance of sea mammals like seals and penguins. These findings were detailed in a review article published today in Nature Sustainability by members of the United Nations Environment Programme's Environmental Effects Assessment Panel, which informs parties to the Montreal Protocol.
Researchers have discovered a mysterious group of neurons in the amygdala -- a key center for emotional processing in the brain -- that stay in an immature, prenatal developmental state throughout childhood. Most of these cells mature rapidly during adolescence, suggesting a key role in the brain's emotional development, but some stay immature throughout life, suggesting new ideas about how the brain keeps its emotional responses flexible throughout life.
For the first time, scientists have been able to study how well synthetic bone grafts stand up to the rigors and 'strains' of life, and how quickly they help bone re-grow and repair.
Researchers led by Dr Gianluca Tozzi, at the University of Portsmouth, are the first to examine the strains between bone and graft from animal models in 3D and in microscopic detail.
Dr Tozzi hopes this window on to living bone grafts will help scientists find ways to improve the body's ability to regrow its own bone, and more chance surgeons can predict the success of a synthetic graft.
Against the background of global warming, extreme heat has occurred more frequently and caused adverse socioeconomic effects. In the midsummer of 2018, a severe extreme heat episode attacked Northeast Asia, causing numerous fatalities. For instance, the extreme heat that attacked Japan in July 2018 resulted in about 24 000 hospitalized patients and more than 90 deaths. To understand what caused the extreme heat over Northeast Asia, a scientific collaboration of climatologists examined the forces of the tropical circulation and sea surface temperature.
Photoreceptor cells in our eyes can adjust to both weak and strong light levels, but we still don't know exactly how they do it. Emeritus Professor Fumio Hayashi of Kobe University and his colleagues revealed that the photoreceptor protein rhodopsin forms transient clusters within the disc membranes in retina. These clusters are concentrated in the center of disc membranes, and act as platforms in the process of light to chemical signal conversion. The findings were published as a highlighted paper in Communications Biology on June 14.
ANN ARBOR--Some patients feel shame, anxiety or fear immediately before seeing their doctor, making them tense. But if they can relax and become calm, patients will likely pay attention to and better comprehend health messages, suggests a new University of Michigan study.
Researchers tested whether increasing one's positive self through meditation can lessen the patient's negative feelings prior to getting the health information.
Philadelphia, June 24, 2019 - The epileptic "aura" is a subjective phenomenon that sometimes precedes the visible clinical features of a seizure. Investigators tested three epileptic patients prior to potential surgery to try to determine where their seizures originate. They observed that these patients reported an ecstatic aura only when the dorsal anterior insula of the brain was stimulated.
Vienna, 24 June 2019: Despite a time limit imposed in many countries on the freeze-storage of sperm, a new study from China has found that the long-term cryopreservation of semen in a sperm bank does not affect future clinical outcomes. Results of the study are presented today in Vienna at the 35th Annual Meeting of ESHRE by Dr Chuan Huang of the Changsa-Hunan Sperm Bank in China.
While exploring the way alien species invade cities around the world, South African PhD student Ashlyn L. Padayachee (University of KwaZulu-Natal, UKZN) and her supervisors, Serban Proches (UKZN) and John Wilson (SANBI and Stellenbosch University) remember suddenly being stricken.
COLUMBUS, Ohio - Young people are less likely to be carded for cigarettes in certain types of shops, particularly in those that heavily advertise tobacco, a new study has found.
When researchers who were 20 and 21 visited a variety of shops in a city on the verge of implementing a law prohibiting sales to people younger than 21, more than 60 percent of cashiers didn't ask them for identification, found the study, which appears online in the American Journal of Health Promotion.
