State gun laws and firearm-related homicides and suicides

JAMA Network Open

2025-07-11

(Press-News.org) About The Study: In this cross-sectional study, stronger gun laws correlated with decreased overall firearm mortality, with the strongest correlations for decreased suicides. For firearm suicide, this analyses lend support to policies that regulate firearm sales, transfers, and permitting laws. While some gun law categories were correlated with decreased firearm homicide, sociodemographic factors, such as unemployment, poverty, and insurance status, correlated with larger changes, suggesting policies that address root causes of violence through economic mobility and access to robust social, health, and educational services may be associated with a greater reduction in homicides.

Use of tobacco and cannabis following state-level cannabis legalization

2025-07-11

About The Study: In this longitudinal cohort study, recreational cannabis legalization was associated with more cannabis and electronic nicotine delivery systems use after 5 years and no significant change in cigarette use. Furthermore, cannabis use increased over time, underscoring the importance of studying commercialization policy going forward. Based on the present results, it is unlikely recreational cannabis legalization has been associated with a large increase in cigarette use, but increases in use of cannabis and vaped nicotine bear close monitoring as retail cannabis rapidly expands.

Long-term obesity and biological aging in young adults

2025-07-11

About The Study: In this multiple-events case-control study, long-term obesity was associated with the expression of biochemical aging markers in adults ages 28 to 31, consistent with epigenetic alterations, telomere attrition, chronic inflammation, impaired nutrient sensing, mitochondrial stress, and compromised intercellular communication. In young adults, chronic health issues may emerge from accelerated biological aging associated with long-term obesity. Corresponding Authors: To contact the corresponding authors, email Paulina Correa-Burrows, PhD, (paulina.correa@inta.uchile.cl) and Christian ...

Orphan nuclear receptors in metabolic dysfunction-associated steatotic liver disease development

2025-07-11

Metabolic dysfunction-associated steatotic liver disease (MASLD), affecting approximately 30% of the global population, represents a spectrum of liver disorders ranging from simple steatosis to metabolic dysfunction-associated steatohepatitis (MASH), fibrosis, and cirrhosis. Its pathogenesis involves complex interactions between genetic predisposition, metabolic dysregulation, inflammation, and cellular stress responses. Orphan nuclear receptors (ONRs), a subfamily of nuclear receptors lacking identified ...

A technological breakthrough for ultra-fast and greener AI

2025-07-11

Artificial intelligence systems like ChatGPT are notorious for being power-hungry. To tackle this challenge, a team from the Centre for Optics, Photonics and Lasers (COPL) has come up with an optical chip that can transfer massive amounts of data at ultra-high speed. As thin as a strand of hair, this technology offers unrivalled energy efficiency. Published in Nature Photonics, the innovation harnesses the power of light to transmit information. Unlike traditional systems that rely solely on light intensity, this chip also uses ...

Pusan National University researchers identify key barriers hindering data-driven smart manufacturing adoption

2025-07-11

Modern manufacturing operates in complex environments where traditional management approaches are no longer enough. This highlights the need for real-time, dynamic and self-adaptive management strategies. Manufacturing data analytics (MDA) has emerged as a powerful solution for transforming traditional manufacturing into smart manufacturing. Through MDA, manufacturers can identify hidden patterns in external and internal data, allowing them to better anticipate and respond to geopolitical risks and rapidly changing customer expectations and demands. However, despite these benefits, adoption of MDA remains surprisingly low, with ...

Inking heterometallic nanosheets: A scalable breakthrough for coating, electronics, and electrocatalyst applications

2025-07-11

Coordination nanosheets are a unique class of two-dimensional (2D) materials that are formed by coordination bonds between planar organic ligands and metal ions. These 2D nanomaterials are increasingly utilized in energy storage, electronic devices, and as electrode-based catalysts due to their excellent electronic, optical, redox properties, and catalytic activity. Over the last decade, coordination nanosheets composed of various transition metal ions, such as nickel (Ni) ions linked to benzenehexathiol (BHT)—an ...

Adults with autism show similar brain mapping of body parts as typically developing adults

2025-07-11

Autism spectrum disorder (ASD), a neurodevelopmental condition, is often associated with difficulties in social communication and repetitive behavior. Previous research reveals that people with ASD often find it challenging to interpret intentions from body language and have difficulty recognizing faces and emotions, which may contribute to their social communication problems. Scientists speculate that these challenges might arise from differences in how the brain perceives faces and body parts, i.e., how individuals with ASD represent the human body. However, until now, no study had clearly mapped how ...

Uncovering behavioral clues to childhood maltreatment

2025-07-11

Childhood maltreatment leaves deep and lasting marks that have far-reaching consequences, extending beyond immediate trauma and affecting survivors in ways that are often invisible and misunderstood. Many survivors often face a complex mix of challenges that have an impact not only on their mental well-being but also on their physical health, social development, and overall quality of life. Studies have shown that the consequences of childhood maltreatment can be truly profound, influencing the risk of chronic health conditions and hindering educational and employment opportunities and lifelong relationships. However, despite the severity ...

Premenstrual symptoms linked to increased risk of cardiovascular disease

2025-07-11

Women diagnosed with premenstrual symptoms have a slightly increased risk of developing cardiovascular disease later in life. This is shown by a new study from Karolinska Institutet published in Nature Cardiovascular Research. Premenstrual symptoms include premenstrual syndrome (PMS) and the more severe form, premenstrual dysphoric disorder (PMDD). The symptoms, which appear a few days before menstruation and then subside, can be both psychological and physical. The study included more than 99,000 women with premenstrual symptoms who were followed for up to 22 years. The researchers compared their health with women without these symptoms – both in the general population ...
