Nicotine pouch and e-cigarette use and co-use among U.S. youths

JAMA Network Open

2025-04-30

(Press-News.org) About The Study: In this cross-sectional study, commercial nontobacco nicotine use in U.S. 10th and 12th graders shifted from 2023 to 2024, marked by a doubling in nicotine pouch past-30-day use, an increase in pouch plus e-cigarette dual use, and a decrease in exclusive e-cigarette use. Prioritizing surveillance, regulation, and prevention addressing pediatric nicotine pouch use warrants consideration.

Wildfire smoke exposure and cause-specific hospitalization in older adults

2025-04-30

About The Study: Exposure to high levels of smoke pollution was associated with an increase in hospitalizations for respiratory diseases in this cohort study. These findings underscore the need for interventions to mitigate the health impacts of wildfire smoke exposure. Corresponding Author: To contact the corresponding author, Rachel C.

Mechanism by which the brain weighs positive vs. negative social experience is revealed

2025-04-30

Mount Sinai researchers have identified for the first time the neural mechanisms in the brain that regulate both positive and negative impressions of a social encounter, as well as how an imbalance between the two could lead to common neuropsychiatric disorders like autism spectrum disorder (ASD) and schizophrenia. The study, published April 30 in Nature, also describes how activating a serotonin receptor in the brain of a mouse model ofASD restored positive emotional value (also known as “valence”), with encouraging implications for the development of future therapies. “The ability to recognize and distinguish unpleasant from pleasant interactions ...

Use of nicotine pouches increases significantly among US teens

2025-04-30

The use of nicotine pouches — small, easily concealed sachets of nicotine and additives that are placed between the gum and lip — nearly doubled among U.S. high school students between 2023 and 2024, according to a new USC study. The research, involving surveys of more than 10,000 teens from around the country, appears in JAMA Network Open. “This growing public health issue needs more attention. Like flavored e-cigarettes when they first emerged, use of this new oral nicotine product is becoming more widespread, particularly among adolescents,” said ...

In two decades increasing urban vegetation could have saved over 1.1 million lives

2025-04-30

Increasing urban vegetation by 30% could save over one-third of all heat related deaths, saving up to 1.16 million lives globally from 2000 to 2019 according to a 20-year modelling study of the impact of increasing greenness in more than 11,000 urban areas. The study, led by Monash University Professor Yuming Guo and published in The Lancet Planetary Health, showed that increasing vegetation levels by 10%, 20%, and 30% would: decrease the global population-weighted warm-season mean temperature by 0.08°C, 0.14°C, ...

Mindfulness therapy reduces opioid craving and addiction, study finds

2025-04-30

Researchers from the University of California San Diego have found that Mindfulness-Oriented Recovery Enhancement (MORE) can help rewire the brain’s response to natural healthy pleasure, leading to improved mood, greater attention to positive experiences and reduced opioid cravings. The findings, published on April 30, 2025 in the Journal of the American Medical Association (JAMA), suggest that this evidence-based therapy may be a promising tool in the fight against opioid use disorder (OUD). Opioid ...

Stronger and safer: New design strategy for aluminium combines strength with hydrogen embrittlement resistance

2025-04-30

Aluminium alloys are well-known for their low weight and corrosion resistance, making them ideal candidates for applications in a low-carbon economy - from lightweight automobiles to tanks for storing green hydrogen. However, their widespread application is limited by a key challenge: they suffer from embrittlement leading to cracking and failure when exposed to hydrogen. Till now, alloys resistant to hydrogen embrittlement were rather soft, limiting their application in hydrogen-related technologies that require high strength. Now, researchers from the Max Planck Institute for Sustainable Materials (MPI-SusMat) ...

Researchers solve one of Earth's ancient volcanic mysteries

2025-04-30

Geologists led by the University of Maryland and the University of Hawaiʻi finally connected the dots between one of the largest volcanic eruptions in Earth’s history and its source deep beneath the Pacific Ocean. In a paper published in the journal Nature on March XX, 2025, the team revealed that the same underwater hotspot created both a chain of underwater volcanoes in the southern Pacific region and the massive Ontong-Java Plateau, the largest volcanic platform on Earth. “Up until now, we’ve had this extremely disconnected picture of the Pacific and its volcanoes,” said the study’s corresponding author ...

Existing treatments may help fight symptoms of severe form of muscular dystrophy, new research suggests

2025-04-30

A new study led by researchers at Hospital for Special Surgery (HSS) suggests that currently available therapies may help control chronic muscle inflammation in Duchenne muscular dystrophy (DMD), a severe condition that leads to muscle weakness and premature death. The study, published in PNAS, identifies new mechanisms that drive chronic muscle inflammation in a disease model of a DMD. Researchers believe that targeting these mechanisms with existing therapies could help reduce inflammation and support muscle function. DMD is caused by a mutation in the dystrophin gene, which produces a large protein essential for stabilizing muscle cell membranes ...

Plastics may trigger hormone disruption in seabirds, new study finds

2025-04-30

SAN DIEGO (April 30, 2025) — Many are aware of the dire challenges with plastic waste polluting the ocean, but new research shows it may harm wildlife in ways not previously understood. In a new study just published in the journal Environmental Pollution, researchers from the University of California, Santa Cruz and San Diego Zoo Wildlife Alliance found that plastic swallowed by northern fulmars— seabirds found in the North Atlantic and North Pacific Oceans—can leak chemicals that interfere with the birds’ hormone systems. This ...

A virtual reality game integrating smell to fight cognitive decline

2025-04-30

As the global population ages, supporting older adults in maintaining their cognitive and memory functions has become a pressing concern. The United Nations estimates that by the 2070s, there will be over 2.2 billion people aged 65 or older, surpassing the global number of children under 18. This demographic shift is especially pronounced in Japan, the fastest-aging country, where 28.7% of the population is 65 or older. One promising strategy to counter cognitive decline is through olfactory stimulation—engaging the sense of smell. Smell signals travel directly to brain regions involved ...
