(Press-News.org) About The Study: Lifetime history of heavy cannabis use was associated with lower brain activation during a working memory task in this study of young adults. These findings identify negative outcomes associated with heavy lifetime cannabis use and working memory in healthy young adults that may be long lasting.

Nourishing T cells to fight cancer
2025-01-28
Researchers from the University of Pittsburgh have developed a new way to grow T cells in the lab that enables them to live longer and better destroy cancer cells in a mouse model of melanoma compared to those grown in traditional growth media.
The findings, published recently in Cell Metabolism, have the potential to greatly improve the effectiveness of cancer immunotherapies that involve taking T cells from a patient and growing them to enormous numbers in the lab before reinfusing them back into the body.
“The way we traditionally grow T cells ...
Temperature exposure and psychiatric symptoms in adolescents from 2 European birth cohorts
2025-01-28
About The Study: In this cohort study, exposure to cold in the Netherlands and heat in Spain were associated with more psychiatric symptoms, highlighting distinct temperature exposure and mental health associations among adolescents. Future studies should explore this across diverse climates to further quantify the intricate and multifactorial association of climate change with mental health.

Standardizing provider assessments reveals important information about gun and opioid access for veterans at risk of suicide
2025-01-28
PHILADELPHIA—Standardizing an assessment process currently used by doctors during care discussions with veterans at risk for suicide in other context could shed more light on the risks related to firearms and opioids.
The findings from researchers at the Perelman School of Medicine at the University of Pennsylvania were reported today in JAMA Network Open. They found that fewer veterans reported having access to firearms than expected—either because some didn't mention it to their doctor, it wasn't ...
The environmental and economic impact of COVID-19 on Japan’s tourism industry
2025-01-28
Fukuoka, Japan—It goes without saying that the tourism industry in Japan is booming. Walk around any major city and you’ll see people from all around the world enjoying the country’s food, culture, and hospitality. Naturally, the revenue generated by the industry has had a positive economic impact throughout Japan. However, between 2020 and 2022, the tourism industry was hit particularly hard due to the COVID-19 pandemic and subsequent travel restrictions. While the government implemented policies ...
Study reveals gaps in healthcare quality assessments across Israel, the US, and the UK
2025-01-28
A new study has taken a closer look at how healthcare quality is measured in three major countries—Israel, the United States, and the United Kingdom—uncovering striking similarities and critical gaps. The research delved into Israel’s Quality Indicators in Community Healthcare (QICH), the US’s Healthcare Effectiveness Data and Information Set (HEDIS), and the UK’s Quality and Outcomes Framework (QOF). While all three systems prioritize family medicine and process-focused metrics, the study highlights a lack of attention to structural and outcome-based ...
Mapping Antarctica’s hidden ice-free lands: a blueprint for conservation
2025-01-28
Antarctica, often regarded as the planet’s last true wilderness, harbours unique ecosystems that support extraordinary biodiversity and contribute to global diversity and environmental stability. These ecosystems, which occupy permanently ice-free land covering less than 0.5% of the continent, are now under growing threat from human activity and climate change.
Now, a team led by researchers at UNSW Sydney’s Centre for Ecosystem Science has developed a high-resolution map and hierarchical classification system of Antarctica’s ice-free lands, which can be seen in full in Scientific Data.
This new inventory categorizes Antarctica’s ecosystems ...
National and gender differences in exclusionary behavior
2025-01-28
When given the power to distribute resources, a person’s nationality, gender, and ideology can help predict how likely that person is to exclude others to maximize their own profit, according to a study. The results suggest that the identities and cultural backgrounds of decision-makers affect how equitably resources are divided.
Andrzej Baranski and Nicholas Haas placed study participants into groups of three to play a negotiation game. All interactions were via computer and no information about the other ...
The journal Genes & Development has new editorial leadership and an expanded scope
2025-01-28
Cold Spring Harbor, NY – Cold Spring Harbor Laboratory Press (CSHL Press) has announced the appointment of new editorial leadership at its renowned journal, Genes & Development. Professor Andrew Dillin has been named Editor-in-Chief, and Dr. Eric Sawey becomes Executive Editor.
These changes are associated with an intentional expansion of the journal’s scope into new and exciting aspects of life science research. While the journal remains committed to its traditional areas of coverage, it will also actively foster additional dynamic fields including physiology, metabolism, aging, gene and environmental interactions, and molecular neuroscience. Genes & ...
Pancreas cells secrete neuroprotective factor
2025-01-28
Pancreas cells may produce a protein that can protect the brain from Alzheimer's disease. In individuals with Alzheimer's disease, a peptide known as amyloid-β accumulates and forms tangled plaques. People with diabetes have a higher probability of developing Alzheimer's disease, raising the possibility of a link between the cells that are disordered in diabetes—pancreatic β cells—and the onset of Alzheimer's disease. However, insulin supplementation may not halt the development of Alzheimer's disease. Toru Hosoi and colleagues ...
