Cigarette smoking is associated with frequent substance use and poor behavioral and physical health in sexual and gender minority populations, according to Rutgers researchers.

The study, published in the journal Annals of Behavioral Medicine, examined tobacco use by sexual minority men and transgender women to better understand the relationships between smoking, substance use and mental, psychosocial and general health.

What The Study Did: Researchers investigated data collection and sharing practices of mobile apps played by preschool-age children and the associated sociodemographic characteristics of the children.

Authors: Jenny S. Radesky, M.D., of the University of Michigan Medical School in Ann Arbor, is the corresponding author.

13 Reasons Why is just one of several widely successful shows to hit our screens in recent years that contains portrayals of suicide, sparking concerns from experts about the potential impact on vulnerable viewers.

In a new paper, University of South Australia researchers have confirmed that portrayals of suicide in moving-image fiction and non-fiction media, such as television and web series, films, and documentaries, has the potential to increase suicidal ideation and behaviour.

DALLAS - Sept. 7, 2020 - Like wrenches made of Legos, SWI/SNF chromatin remodeling complexes tighten or loosen DNA in our cells to control how genes are turned on and made into proteins. When assembled correctly, these complexes play a crucial role in the development of normal tissues, and when broken, they can lead to the development of cancer. These complexes are commonly disrupted by mutations in the genes that encode them - but how this leads to cancer is poorly understood.

Electric current is everywhere, from powering homes to controlling the plasma that fuels fusion reactions to possibly giving rise to vast cosmic magnetic fields. Now, scientists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have found that electrical currents can form in ways not known before. The novel findings could give researchers greater ability to bring the fusion energy that drives the sun and stars to Earth.

SAN ANTONIO, Texas, USA - Multisystem inflammatory syndrome in children (MIS-C), believed to be linked to COVID-19, damages the heart to such an extent that some children will need lifelong monitoring and interventions, said the senior author of a medical literature review published Sept. 4 in EClinicalMedicine, a journal of The Lancet.

Less screen time and more green time are associated with better psychological outcomes among children and adolescents, according to a study published September 4 in the open-access journal PLOS ONE by Tassia Oswald of the University of Adelaide, and colleagues.

In March, in the early days of the coronavirus pandemic in Europe, a tweet from the French Health Minister, Olivier Verán, advised patients with COVID-19 not to take ibuprofen, an anti-inflammatory drug with analgesic and antipyretic properties. He even warned that taking it would increase mortality among COVID-19 patients, even though the statement was not backed by any scientifically valid evidence. In spite of this information's spuriousness, it subsequently spread to a number of countries.

In 2015, a team of specialists in modeling disease outbreaks got together with educators to create Operation Outbreak, an educational platform and simulation intended to teach high school and college students the fundamentals of responses to pandemics. The program, which is open source and freely available, was designed to simulate outbreaks with different variables (such as R0 and mode of transmission) and to generate data in the context of real human behavior. It includes a Bluetooth-based app that carries out contact tracing by recording transmission events between phones.

A Dartmouth-led study using multisensor drones has revealed a large circular earthwork at what may be Etzanoa, an archaeological site near Wichita, Kansas. Archaeologists speculate that the site was visited by a Spanish expedition, led by Juan de Oñate, a controversial conquistador, in 1601.

A biologist from RUDN University found the most beneficial concentration of tryptophan for rainbow trout. When added to the diet of the fish, this amino acid supports the immune system and reduces the oxidative stress in the intestinal tract caused by the overpopulation of fish farms. The results of the study were published in the Aquaculture magazine.

Key Points

An estimated 15.7% of children hospitalized for severe acute malnutrition die before they are discharged.

Presence of HIV infection, diarrhea, pneumonia, shock, lack of appetite and low weight-to-height ratio raises the risk of mortality among these children, with some studies reporting mortality rates of to up to 40%.

Children with low weight-to-height ratio at hospital admission are at highest risk of mortality.

Early identification of prognostic factors, alongside risk stratification at hospital admission, may reduce mortality.

WASHINGTON -- Performing acts of kindness and helping other people can be good for people's health and well-being, according to research published by the American Psychological Association. But not all good-hearted behavior is equally beneficial to the giver. The strength of the link depends on many factors, including the type of kindness, the definition of well-being, and the giver's age, gender and other demographic factors.

The study was published in the journal Psychological Bulletin.

Hershey, Pa. -- A new technology that uses a protein's structure to predict the inner wiring that controls the protein's function and dynamics is now available for scientists to utilize. The tool, developed by researchers at Penn State, may be useful for protein engineering and drug design.

The team produced and studied new active photocatalysts based on natural aluminosilicate nanotubes with cadmium sulfide quantum dots stabilized on their surface synthesized by self-assembly.
