A new study finds that mental health problems in adults are more likely to persist today than they were ten years ago. The research suggests conditions such as anxiety and depression are lasting longer rather than resolving, pointing to a shift in the nature of adult mental ill health. The findings add to ongoing concern among health experts about rising and increasingly chronic psychological distress across the adult population.

Two landmark studies published with backing from the World Organisation for Animal Health conclude that current legislation is insufficient to protect wildlife, and call for stronger legal frameworks worldwide. The findings point to gaps in existing protections for wild animal populations and urge policymakers to tighten rules. The announcement is drawing attention among conservation and animal health communities.

PBS NewsHour reports on scientists developing new ways to control mosquito populations as rising global temperatures expand the habitats where the insects and the diseases they carry can spread. The segment examines research approaches to targeting mosquitoes as warming climate conditions push the public health threat into previously unaffected regions.

New research highlights that people living with severe mental illness die more than 10 years earlier than the general population. Researchers point to contributing factors behind the gap, which is widely attributed in the field to physical health conditions going undertreated, higher rates of smoking and cardiovascular disease, medication side effects, and poorer access to healthcare. The finding has renewed calls to close the life-expectancy gap for this group.

Advocates are calling for mental health diversion programs instead of incarceration at New York City's Rikers Island jail, where thousands of people in custody reportedly need mental health treatment. The push reflects growing criticism that the jail system is being used as a de facto mental health facility, with reformers arguing treatment-based alternatives would be more effective and humane.

The Nigerian Correctional Service says a cholera outbreak at the Kano Custodial Centre has been contained. The service announced that the situation at the detention facility is now under control, with no further details given on the number of inmates affected or whether there were any fatalities. Health authorities typically respond to such outbreaks in custodial facilities with isolation, treatment and improved sanitation to prevent spread among the confined population.

Health officials in Los Angeles are investigating an outbreak of flea-borne typhus in the Wilshire Center neighborhood. Fox 11 Los Angeles reports the probe is underway, and local residents are discussing the news amid concerns about rodent populations, stray animals and how the bacterial illness, spread by fleas, may have taken hold in the urban area.

A laboratory at Caltech in Pasadena has been awarded $2.4 million to investigate where infertility may begin. The funding will support research into the earliest biological roots of infertility, an issue affecting many people worldwide. Details on the specific researchers or lines of study involved have not yet been made widely available.

New figures from the European Commission show that 5% of Europeans consumed alcohol every day in 2025. The statistic highlights that despite overall declines in drinking across much of the continent, a small but notable share of the population still drinks daily, a pattern linked in public health research to higher risks of liver disease, cancer and other harms. Health advocates are likely to use the data in ongoing debates over alcohol pricing, advertising and labelling rules across EU member states.

Researchers at the University of Colorado Anschutz Medical Campus are examining temporary firearm removal policies aimed at service members and veterans at risk of suicide. The research explores how extreme risk protection orders and similar measures could reduce gun deaths in military communities, a population disproportionately affected by suicide. The findings are drawing attention amid ongoing national debate over gun safety and veteran mental health.

Hillsborough County has asked Lee County for assistance with mosquito control as Florida responds to a dengue outbreak. Dengue is spread by mosquitoes, and local health officials have been urging residents to guard against bites. The request highlights growing concern across Florida counties about containing the outbreak before mosquito populations spread the virus further.

A new situation analysis examines how well health systems across the Eastern Mediterranean Region include people with disabilities. The report, published via ReliefWeb, reviews barriers to accessible care and the state of disability inclusion in regional health services. It is expected to inform policymakers and health organisations working to meet the needs of an estimated population that often faces unequal access to treatment.

Reports highlight the growing functional nutrition sector in Asia, driven by demand from both young consumers seeking health-boosting products and older populations needing age-specific dietary support. Manufacturers are reformulating foods and beverages with added vitamins, probiotics and other functional ingredients to serve a market shaped by demographic change across the region.

Iowa State University researchers are working on ways to reduce firefighters' elevated risk of cancer, which has been linked to exposure to toxic chemicals and smoke on the job. The Gazette reports on the effort, which comes as firefighting is increasingly recognised as a hazardous occupation with higher cancer rates than the general population.

The Gándara Center is working to improve access to mental health care for Latino communities, according to reporting by WWLP. The organization, which serves Latino and multicultural populations in Massachusetts, focuses on culturally appropriate behavioral health services. The report highlights ongoing efforts to close gaps in care for a population that has historically faced barriers to treatment.

Investment firms ARCH and Population Health are returning to China to back a new startup focused on sleep disorders. The company will target diagnosis and treatment of sleep-related conditions in the Chinese market. It marks a renewed China commitment for the two investors, and observers are watching whether demand for sleep health products can support a standalone business there.

Researchers have developed a new index that connects changing ocean food webs to Bermuda's spiny lobster fishery. The tool is intended to help track how shifts in marine ecosystems, such as changes in prey availability, affect lobster populations and the local fishing industry that depends on them. The work offers a way to monitor ecosystem health and inform management of the fishery.

New research from Epic Research finds that patients diagnosed with a gambling disorder have far higher rates of other diagnosed mental health conditions than the general patient population. The findings add to growing evidence that problem gambling rarely occurs in isolation and is often accompanied by conditions such as depression or anxiety. Health researchers are highlighting the study as a reason for better screening and integrated treatment for people seeking help with gambling.
