Glucagon-like peptide-1 receptor agonists and age-related macular degeneration

JAMA Ophthalmology

2025-10-23
(Press-News.org) About The Study: In this cohort study, glucagon-like peptide-1 receptor agonist (GLP-1RA) use was associated with reduced risk of developing nonexudative age-related macular degeneration (AMD) but was not associated with progression to exudative AMD among individuals with nonexudative AMD. These findings may inform future randomized trials evaluating the ocular effects of GLP-1RAs in nondiabetic populations.

Prenatal exposure to fine particulate matter components and autism risk in childhood

2025-10-23
About The Study: In this large cohort study, prenatal exposure to specific fine particulate matter (PM2.5) components and postnatal ozone (O3) exposure were associated with autism spectrum disorder risk. The second and third trimesters may represent sensitive exposure windows. These findings support further research on air pollution’s role in autism spectrum disorder etiology.  Corresponding Author: To contact the corresponding author, Eric Lavigne, PhD, email eric.lavigne@hc-sc.gc.ca.

Light exposure at night and cardiovascular disease incidence

2025-10-23
About The Study: In this cohort study, night light exposure was a significant risk factor for developing cardiovascular diseases among adults older than 40 years. These findings suggest that, in addition to current preventive measures, avoiding light at night may be a useful strategy for reducing risks of cardiovascular diseases.  Corresponding Author: To contact the corresponding author, Daniel P.

Shining a light on heart disease risk

2025-10-23
A new study led by Flinders University has found that being exposed to bright light at night can significantly increase the chances of developing serious heart problems, including heart attacks, strokes and heart failure. Published in JAMA Network Open, the research is the largest study of its kind to explore how personal light exposure affects heart health using data from nearly 89,000 people in the UK. Using wrist-worn sensors, researchers from FHMRI Sleep Health tracked over 13 million hours of light exposure and followed participants for up to 9.5 years. The study found that people who were exposed to the brightest light at night were much more likely to develop ...

PAI-1 deficiency protects aging female mice from muscle and bone loss

2025-10-23
“These results indicate that PAI-1 is partly involved in aging-related sarcopenia and osteopenia in female mice, although the corresponding mechanisms remain unknown.” BUFFALO, NY — October 23, 2025 — A new research paper was published in Volume 17, Issue 9 of Aging-US on September 11, 2025, titled “Roles of plasminogen activator inhibitor-1 in aging-related muscle and bone loss in mice.” In this study led by first author Takashi Ohira and corresponding author Hiroshi Kaji from Kindai University Faculty of Medicine, researchers found that female mice lacking the gene for plasminogen ...

Snake bites: How they do it

2025-10-23
Few actions in nature inspire more fear and fascination than snake bites. And the venomous reptiles have to move fast to sink their fangs into their prey before their victim flinches, which may be as little as 60 ms when hunting rodents. Until recently, video technology was not sufficiently sophisticated to capture the deathly manoeuvres in high definition, but recent improvements have made this possible, so Alistair Evans and Silke Cleuren from Monash University, Australia, decided to get to the heart of how venomous viper, ...

New antibody restricts the growth of aggressive and treatment-resistant breast cancers

2025-10-23
A new potential antibody therapy strategy which restricts the growth of treatment-resistant breast cancers has been developed by scientists. The King’s College London discovery, published today, could provide new treatment options for some of the most aggressive forms of breast cancer. This may be particularly important for patients whose cancers no longer respond to existing therapies, as well as those with triple-negative breast cancer – a subtype which lacks the receptors which are common drug targets, where treatment choices remain very limited. The team designed an antibody that not only attacks the tumour cells directly, but also harnesses the body’s own immune ...

Newly discovered ‘super-Earth’ offers prime target in search for alien life

2025-10-23
UNIVERSITY PARK, Pa. — The discovery of a possible “super-Earth” less than 20 light-years from our own planet is offering scientists new hope in the hunt for other worlds that could harbor life, according to an international team including researchers from Penn State. They dubbed the exoplanet, named GJ 251 c, a “super-Earth” as data suggest it is almost four times as massive as the Earth, and likely to be rocky planet. "We look for these types of planets because they are our best chance at finding life elsewhere,” said Suvrath Mahadevan, the Verne M. Willaman Professor of Astronomy at Penn State and co-author ...

Transport and dispersion of radioactive pollutant in the Northern South China Sea

2025-10-23
This study was led by Jinxiao Hou, Dr. Xiaolin Hou, and Dr. Yanyun Wang from the Institute of Earth Environment, Chinese Academy of Sciences. The northern offshore region of the South China Sea hosts one of the highest densities of nuclear power plants along China’s coastline. By systematically collecting seawater samples throughout this area and applying the laboratory’s well-established ultra-trace analytical techniques for ¹²⁹I and ¹²⁷I, the team measured the concentration levels and spatial distributions of both isotopes. By integrating observed ¹²⁹I/¹²⁷I atomic ...

Loneliness interventions help but are not a cure-all

2025-10-23
Interventions designed to reduce loneliness can be effective, but do not yet offer a complete solution to what is becoming a worldwide public health problem, according to research published by the American Psychological Association.   “Loneliness is now widely acknowledged as a serious public health concern linked to depression, anxiety, cardiovascular disease and even early mortality,” said lead author Mathias Lasgaard, PhD, of the Central Denmark Region and University of Southern Denmark. “Our findings provide strong evidence that interventions can make a difference, though their overall impact remains modest. Loneliness does not have a one-size-fits-all ...

Nearly 1 in 5 urinary tract infections linked to contaminated meat

2025-10-23
WASHINGTON (Oct. 23, 2025) — A new study estimates that nearly one in five urinary tract infections in Southern California may be caused by E. coli strains transmitted through contaminated meat – and pose a hidden foodborne risk to millions of people not just in California but across the US. The research, published in mBio, also found that people living in low-income neighborhoods are at the greatest risk. “Urinary tract infections have long been considered a personal health issue, but our findings suggest that they are also a food safety problem,” said Lance B. Price, senior author of the ...
