Aerial and hand distribution of oral rabies vaccine baits for wildlife is set to begin Wednesday across the Tri-Cities area of northeast Tennessee and southwest Virginia. Health and wildlife officials run the annual drop to immunize raccoons and other animals and stop the spread of rabies toward populated areas. Residents are advised to leave the baits alone and keep pets away from them.

Attention is turning to how a warming climate could affect malaria. Rising temperatures and shifting rainfall patterns can expand the range of the mosquitoes that transmit the disease, exposing new populations while changing transmission seasons in existing hotspots. Commenters and data outlets are weighing how significant the added burden could be, and which regions are most vulnerable.

Researchers have published global and regional reference curves for pain across the human lifespan, drawing on data from 6.1 million individuals in 118 countries. The study, appearing in Nature, offers age-standardised benchmarks for how pain prevalence changes from childhood to old age, allowing clinicians and researchers to compare pain levels across regions and populations.

Nearly 30,000 people in Israel have been treated for psychological trauma since the Gaza war began, according to figures reported by Anadolu Agency. The toll highlights the mental health impact of the conflict on Israelis, alongside the physical casualties, as rocket alerts, losses and displacement continue to strain the population.

Health officials in Pennsylvania are contending with the state's largest measles outbreak since the early 1990s. The report from FOX 29 Philadelphia flags a significant public health concern, with measles cases spreading at a scale not seen in the state for over three decades. Authorities are expected to urge vaccination and monitor close contacts as the outbreak develops.

New reporting highlights how the financial strain of war — rising prices, lost income and economic instability — takes a measurable toll on mental health alongside its physical and humanitarian costs. Experts point to growing psychological distress among civilians whose livelihoods are upended by conflict, warning that economic hardship can compound anxiety, depression and trauma in war-affected populations.

Researchers writing in Frontiers estimate the world's oyster reefs could contribute $12 trillion annually to planetary health if they were better managed. The figure reflects the reefs' role in filtering water, protecting coastlines and supporting marine biodiversity, all of which have declined as oyster populations have collapsed worldwide. The finding is drawing attention to oyster reef restoration as a high-value but underused conservation strategy.

Wildlife Services plans to distribute oral rabies vaccines for raccoons across western North Carolina, part of ongoing efforts to control rabies in wild animal populations. The program typically involves bait packets scattered in rural and wooded areas for raccoons to eat, immunizing them against the virus and reducing transmission risk to pets and people.

Virginia has opened a public comment period on how environmental justice is considered in the state's permitting process. The effort, reported by Bay Journal, would examine how permits for industrial and other facilities affect communities already burdened by pollution. Residents and advocacy groups can weigh in on whether permit decisions adequately account for cumulative health and environmental impacts on vulnerable populations.

Stanford Medicine researchers report that biological aging markers could help predict long-term health outcomes in patients who have undergone Fontan surgery, a procedure used to treat single-ventricle congenital heart defects. The findings suggest measuring biological rather than chronological age may offer clinicians a new tool for monitoring complications and guiding care as these patients grow older.

The National Health Law Program (NHeLP) has submitted comments on a federal request for information regarding health reform. The legal advocacy organization, which focuses on protecting access to health care for low-income and underserved populations, used the filing to press its positions on how reform should safeguard coverage and patient protections. The move is part of NHeLP's ongoing advocacy work around national health policy.

NPR reports that wildfire smoke is affecting animals in ways scientists are only beginning to understand. Researchers are studying how smoke exposure influences birds and other wildlife, from breathing and behavior to broader ecological effects, as fires grow more frequent and intense. The emerging field of smoke ecology aims to fill major gaps in knowledge about long-term health impacts on wild animal populations.

Southern California is sweltering under an intense heatwave, with record high temperatures registered across the region. Residents are contending with dangerous heat conditions, and forecasters are monitoring how long the extreme temperatures will persist. Heat events of this scale typically raise concerns about strain on the power grid, wildfire risk and public health, particularly for vulnerable people and outdoor workers.

Canadian researchers have concluded that standard time is likely better for population health than daylight saving time. The finding, circulated via the Australian Science Media Centre, adds to ongoing debate in several countries about whether to keep clock changes or adopt a permanent time system. Researchers argue that misalignment with natural daylight from daylight saving time may harm sleep and overall health.

Reports of a plague case in Russia are drawing attention online, with commentary urging people to monitor the situation closely. Plague occurs sporadically in parts of Russia and Central Asia, typically in marmot and rodent populations, and isolated cases occasionally surface. Observers are watching whether health authorities confirm the report and contain the spread.

Florida is experiencing an outbreak of dengue fever, with cases rising across the state. A Tulane University mosquito researcher has broken down the drivers behind the increase, offering insight into how mosquito populations and climate conditions are contributing to the spread of the disease. Health officials are monitoring the situation as concerns grow about mosquito-borne illness in the region.
