Trends in county-level MMR vaccination coverage in children in the United States

JAMA

2025-06-02

(Press-News.org) About The Study: This county-level dataset complements the state and national-level Centers for Disease Control and Prevention data, confirming a widespread decline in measles-mumps-rubella (MMR) vaccination rates in the U.S. after the COVID-19 pandemic while revealing significant heterogeneity in vaccination patterns within and across states. This dataset can be used in spatial and statistical analyses to identify factors associated with low or declining MMR rates in U.S. counties and help inform targeted vaccination strategies to reduce the risk of measles outbreaks.

Brewed for longevity: drinking coffee linked with healthy aging in women

2025-06-02

Findings from a new study of almost 50,000 women followed for 30 years suggest that a morning cup of coffee might do more than boost energy; it could also help women stay sharp, strong and mentally well as they age. The analysis found that women who drank caffeinated coffee in midlife were more likely to exhibit healthy aging. However, the researchers didn’t find any links with tea or decaf coffee, while drinking more cola was tied to a significantly lower chance of healthy aging. “While past studies have linked coffee to individual health outcomes, our study is ...

Researchers find early driver of prostate cancer aggressiveness

For more information, contact: Nicole Fawcett, nfawcett@umich.edu EMBARGOED for release at noon ET June 2, 2025 Researchers find early driver of prostate cancer aggressiveness Study links higher expression of the gene PROX1 to aggressive change in prostate tumor cells; FDA-approved class of drugs can disable PROX1 ANN ARBOR, Michigan — Researchers at the University of Michigan Rogel Cancer Center identified a gene that plays a key role in prostate cancer cells that have transitioned to a more aggressive, treatment-resistant form. ...

Insect protein blocks bacterial infection

2025-06-02

A protein that gives fleas their bounce has been used to boot out bacteria cells, with lab results demonstrating the material’s potential for preventing medical implant infection. The collaborative study led by researchers at RMIT University in Australia is the first reported use of antibacterial coatings made from resilin-mimetic proteins to fully block bacteria from attaching to a surface. Study lead author Professor Namita Roy Choudhury said the finding is a critical step towards their ...

New study casts doubt on the likelihood of a Milky Way – Andromeda collision

2025-06-02

Scientists from Helsinki, Durham and Toulouse universities used data from NASA’s Hubble and the European Space Agency’s Gaia space telescopes to simulate how the Milky Way and Andromeda will evolve over the next 10 billion years. The two galaxies are currently heading towards each other at a speed of about 100 kilometres per second. A collision would be devastating for both galaxies which would be destroyed, leaving behind a spheroidal pile of stars known as an elliptical galaxy. The team ran 100,000 simulations of both galaxies based on the latest observational ...

Prevalence of artificial sweetener neotame in U.S.-marketed disposable e-cigarettes

2025-06-02

About The Study: This study demonstrates that the artificial sweetener neotame was a ubiquitous constituent of popular disposable e-cigarettes sold in the U.S. in 2024, including those containing no nicotine or the nicotine analogue 6-methylnicotine. Neotame is 7,000 to 13,000 times sweeter than table sugar and is 35 to 65 times sweeter than aspartame. Corresponding Author: To contact the corresponding author, Sven E.

E-cigarette warnings lower vaping interest and raise quit intentions

2025-06-02

Chapel Hill, NC — Electronic-cigarette warnings are effective in discouraging vaping, with warnings specific to health harms being generally more effective than warnings about e-cigarette addiction, according to a meta-analysis of 24 studies conducted by University of North Carolina Lineberger Comprehensive Cancer Center researchers and their colleagues. The researchers also found no negative unintended consequences of e-cigarette warnings, such as encouraging people to smoke cigarettes instead of vaping. The results will be published in JAMA Internal Medicine on June 2. “This is the first meta-analysis that has tested the effectiveness of e-cigarette warnings ...

Record high: Study finds growing cannabis use among older adults

2025-06-02

Marijuana use among older adults in the US has reached a new high, with 7 percent of adults aged 65 and over who report using it in the past month, according to an analysis led by researchers with the Center for Drug Use and HIV/HCV Research (CDUHR) at the NYU School of Global Public Health. Their findings, published in JAMA Internal Medicine, also show that the profile of those who use cannabis has changed in recent years, with pronounced increases in use by older adults who are college-educated, married, female, and have higher incomes. “Our study shows that ...

Trends in past-month cannabis use among older adults

2025-06-02

About The Study: Between 2021 and 2023, prevalence of current cannabis use increased among adults age 65 or older nationally, with key demographic subgroups experiencing marked increases. Adults with the highest incomes initially had the lowest prevalence of cannabis use vs other income levels, but by 2023, they had the highest prevalence, which may indicate better access to medical cannabis given its costs.

How to create aqueous 100 nm-sized materials with polycavities

2025-06-02

While molecues with a single cavity have been extensively studied in solution, the solution state functions of polycavity materials remain elusive owing to their synthetic inaccessibility. Porous aromatic polymers (PAPs) are synthesized in a single step and offer polymeric cavity frameworks with high stability, which are applicable to gas and molecule adsorption/separation only in the solid state. Due to their strong aggregation-derived insoubility, unsubstituted PAPs cannot be used in any solvent until now. To move the functions of PAPs from the solid to the solution ...

Epilepsy is more common in patients with frontotemporal dementia than expected

2025-06-02

According to a recent study, in patients with frontotemporal dementia (FTD), epileptic seizures are significantly more common than previously known. The discovery deepens understanding of the symptoms of this memory disorder and emphasises the importance of taking epileptic seizures into account in the treatment and monitoring of patients. Coordinated by Neurocenter Finland, this major project by the University of Eastern Finland and the University of Oulu examined the prevalence of epilepsy in patients with FTD. The research dataset ...
