Parents of teens who went through puberty early may be more lenient when it comes to letting them consume alcohol, according to a new Penn State study. But the researchers said that even if adolescents appear more mature, drinking alcohol is still not safe for them.

A new GeneSight Mental Health Monitor national survey finds 83 percent of those diagnosed with depression say life would be easier if others could understand what they're going through. Yet, most reported they were more likely to hear statements that demonstrate a lack of understanding and support for what they are experiencing.

A new study shows growing evidence that Pennsylvania's 500 ft. unconventional natural gas (UNG) well setback distance may not be protective against routine exposures to toxic substances such as benzene, hydrogen sulfide, carbon disulfide and PM2.5. This is the first study to assess the effectiveness of setback regulations for UNG development, and the findings suggest that protectiveness of setback policies also depends upon opportunities for exemptions from these siting restrictions.

A new study examined why early developing 14-year-old adolescents are more likely to drink alcohol compared to those whose pubertal development is on-time or late. The findings show these adolescents are more likely to have peers who drink alcohol and are also given greater permission to drink by their parents.

Decision making problems involving multiple agents are often solved using policy iteration, in which a given policy generates a better one. However, the required amount of computation is often prohibitively large. In a new study, a computer scientist takes things to the next level with an approach where decisions are made sequentially and the computations grow only linearly with agents, drastically reducing its complexity and opening doors to a revolution in studying multiagent systems.

Researchers at the National Food Institute, Technical University of Denmark, have generated a lactic acid bacterium that efficiently secretes a food-grade preservative when grown on dairy waste.

Over recent decades, volunteer environmental monitoring (often called "citizen science") has exploded in popularity, aided both by smartphones and rapid gains in computing power that make the analysis of large data sets far easier.

In a first-of-its-kind study, scientists from the UK and Germany used drones to provide a synchronised bird's eye view of what seabirds see and how their behaviour changes depending on the movement of tidal flows beneath them.

First longitudinal study to track violent rumination in over 1,000 teenagers suggests that experiencing different types of victimisation increases likelihood of thinking about hurting or killing people.

For the first time, researchers have systematically analysed social and clinical factors associated with psychiatric hospital admission of children and adolescents, finding nearly one-quarter (23.6%) were admitted involuntarily. The study was published in The Lancet Child & Adolescent Health journal.

One in four people experience mild, short lived systemic side effects after receiving either the Pfizer or AstraZeneca vaccine, with headache, fatigue and tenderness the most common symptoms. Most side effects peaked within the first 24 hours following vaccination and usually lasted 1-2 days.

A team of the University of Michigan (U-M), spearheaded by Nigel Michki, a graduate student, and Assistant Professor Dawen Cai in the departments of Biophysics (LS&A) and Cell and Developmental Biology at the Medical School, identified many genes that are important in fruit flies' neuron development, and that had never been described before in that context.

Having grown up poor in a rural village in Zimbabwe, Wilson Majee saw firsthand as a child the lack of educational opportunities that were easily accessible and how that impacted the youth in his village.

In a randomized, double-blind trial of patients with acute undifferentiated agitation in the emergency department, droperidol was more effective for sedation and was associated with fewer episodes of respiratory depression than lorazepam or either dose of ziprasidone.

MIT researchers developed a machine-learning technique that uses an image to estimate the stresses and strains acting on a material. The advance could accelerate engineers' design process by eliminating the need to solve complex equations.

Researchers with the Peter O'Donnell Jr. Brain Institute at UT Southwestern have identified a new protein implicated in cell death that provides a potential therapeutic target that could prevent or delay the progress of neurodegenerative diseases following a stroke.

Researchers at Gladstone Institutes established a detailed atlas of the CD4+ T cells in individuals with HIV not on antiretroviral treatment, using a technology called CyTOF/PP-SLIDE, which they have honed over the years. The atlas is now published in the scientific journal Cell Reports.

People with diseases such as rheumatoid arthritis and lupus are more likely to have heart attacks, angina, and strokes. A review of the scientific literature on the subject shows that regular exercise improves vascular function in these patients

Industrial fleets from countries around the world have been increasingly fishing in African waters, but with climate change and increasing pollution threatening Africa's fish stocks, there is a growing concern of the sustainability of these marine fisheries if they continue to be exploited by foreign countries.

A promising new concept presented by an interdisciplinary research team paves the way for major advances in the field of magnetic resonance imaging (MRI). Their new technique could significantly simplify hyperpolarized MRI. The proposal involves the hyperpolarization of the metabolic product fumarate using parahydrogen and the subsequent purification of the metabolite.
