The people are receiving follow-up care; the vaccinated dog is well under quarantine. Officials are investigating the rabies variant and urge residents to avoid handling wildlife.

Canada plans legislation indefinitely delaying assisted dying for people whose sole condition is mental illness, Justice Minister Sean Fraser said, BBC News reports. Expansion had been scheduled for March 2027. Fraser cited disagreement over eligibility and irremediability; supporters challenge the exclusion in court. The announced legislation has not yet passed.

Hadza communities in Tanzania and Tsimane communities in Bolivia shared many gut bacterial species despite their distance, NPR reports on a Stanford-led study. Genetic dating suggests some strains travelled with human migrations thousands of years ago. The evolutionary-history interpretation is supported by comparisons; the health effects of microbes lost in industrialized populations remain uncertain.

University of Otago researchers modeled 30% lower hospitalization risk over five years among more than 17,000 children enrolled in New Zealand’s Healthy Homes Initiative, Phys.org reports. The program provides heating, insulation and other improvements to low-income homes. The analysis estimates benefits from program data; it is not a randomized trial.

An Epic Research analysis of over 85 million adults’ records found sharply lower shingles rates among cohorts born after routine childhood chickenpox vaccination began, Fox News reports. The authors say this pattern is consistent with a vaccination benefit. They did not verify individual vaccination histories, so the observational study does not prove that vaccination caused the difference.

Uppsala University reports through Phys.org that some neural stem cells survived unexpectedly long handling after an ISS experiment and later developed into neurons and glial cells in laboratory tests. Cells in 3D-printed supports fared particularly well. The new account describes research from a 2024 flight and possible future space-medicine uses, not a demonstrated treatment.

Bridge Neurotech launched with $13.5 million in funding to develop a wearable ultrasound brain-computer interface, Wired reports. Its initial study records volunteers’ brain activity without delivering treatments or diagnoses. Experts note that blood-flow signals lag neural activity; a working consumer or therapeutic product has not been demonstrated.

Griffith University researchers interviewed 22 survivors, health professionals and employers about returning to work after cancer, Phys.org reports. They identified persistent fatigue, cognitive effects and workplace barriers, and offered 13 recommendations. The findings come from a small qualitative study, rather than a population-wide estimate of how often these barriers occur.

BD plans $3 billion in US medical-product manufacturing within a broader $19 billion multiyear investment commitment, OAN and Reuters report. The agreement ties future tariff relief on covered products and inputs to agreed milestones and the final scope of tariff measures. The spending and expanded domestic supply are plans, rather than completed production.

Kenyan health officials quarantined ten contacts of the country’s first Ebola patient and are tracing 57 others, BBC News reports. The traveler died in Nairobi after arriving from DR Congo via Uganda. Africa CDC is investigating screening gaps and coordinating a regional response. An imported case and exposed contacts do not establish wider Kenyan transmission.

Johns Hopkins researchers found that pulse oximeters shifted from overestimating to underestimating blood oxygen at higher levels across five years of hospital data, STAT reports. Errors were worse for patients of color. Manufacturer Masimo says available data do not establish the cause; the study leaves the shift unexplained.

Governor Kathy Hochul declared a statewide measles disaster emergency after New York recorded 108 cases this year, WXXI reports.

The White House says eligible Medicare Part B enrollees will receive a one-time $90 payment in October from the Medicare Improvement Fund, the Associated Press reports through STAT. CMS says people already receiving premium assistance, paying income-adjusted premiums, or enrolled in Medicare Advantage are excluded. The announcement is a payment commitment, not confirmation that checks have arrived.

CMS Administrator Mehmet Oz told Fox News that insurers should work with brokers who record conversations with Affordable Care Act applicants, part of the administration’s campaign against unauthorized enrollments. Officials attribute large savings to removing accounts they say are ineligible; the interview does not independently establish each account’s status or the projected savings.

Pennsylvania reported 1,078 measles cases across 41 counties, 207 hospitalizations and five measles-associated deaths, the state health department says. More than 40 of the 74 cases added Wednesday concern illnesses over two weeks old, so the update does not establish a current surge. Ars Technica reports 1,066 cases belong to the outbreak that began in April.

NTU researchers designed a compound that blocks an energy-producing enzyme in Mycobacterium abscessus, Phys.org reports. Combined with clofazimine, it reduced bacteria by two logs over four days in laboratory tests. The work remains preclinical; the report describes patent and licensing activity, without demonstrated patient benefit.

UAMS reports that community health workers Sandra Cooper and Wonda Miller developed food-bank partnerships and community gardens after encountering hunger among rural Arkansas participants in a tobacco-cessation study. They trained as master gardeners and now help residents grow produce. The university account describes their activities; it does not report measured health or food-security outcomes.

A study of Medicaid claims for nearly 230,000 people aged 13–25 found major gaps in opioid-use-disorder care, STAT reports. About half began care; among those engaged in treatment, roughly one in six received medication and one in 32 continued for six months. Medication access improved only modestly over 2016–2023, while sustained treatment remained uncommon.

Kansas State researchers studying Logan’s connected elementary school and nursing home report encouraging results after a year of data collection, in an account published by Phys.org. Among 30 residents assessed twice, depression symptoms fell and independence increased while cognition stayed stable. Children also showed gains in development and test scores. These preliminary observations do not establish that the shared facility caused the improvements.

Researchers reconstructed potential compound-making pathways from fragmented microbial DNA and synthesized six candidates, the American Society for Microbiology reports through Phys.org. Tests across seven cancer cell lines found differing activity, with two compounds standing out. The work offers leads for further experiments; it has not demonstrated a safe or effective cancer treatment in animals or people.

A Massachusetts judge rejected Lindsay Clancy’s request for an acquittal after her murder trial ended with a deadlocked jury, AP reports in The Guardian. Judge William Sullivan said the evidence was sufficient for a jury to decide the charges over her three children’s deaths. The defense argued she lacked criminal responsibility because of mental illness; the ruling is not a guilty verdict.

Pomerene Hospital in Millersburg, Ohio, says it was selected for federal Rural Hospital Provider Assistance Program funding. HRSA’s award list confirms the hospital among 132 recipients across 13 states, totaling nearly $25 million. Pomerene’s individual award amount and spending plan were not specified.

A proposed redesign of the National Health Interview Survey would cut its adult questionnaire from 482 questions to 150 and remove several disability measures, STAT reports. Advocates warn it could deepen existing gaps in counting people with intellectual and developmental disabilities. HHS said the redesign aims to lower collection costs; the changes remain a proposal.

Vaccination is offered at clinics and community posts; the campaign’s reach and results are not yet known.

A federal judge removed community-integration provisions from HHS disability regulations after the Justice Department joined states seeking the change, NPR reports. Disability advocates warn it could weaken support for living at home rather than in institutions. The ruling leaves the ADA, Section 504 and the Olmstead precedent intact; practical enforcement remains contested.

A study of US astronauts found higher hip-fracture rates after spaceflights lasting more than 90 days, Phys.org reports from Mayo Clinic Proceedings. Researchers did not find a higher rate of fractures overall. The small astronaut population limits precision; the findings support longer-term bone monitoring rather than establish that every long mission causes fractures.

Los Angeles County’s half-cent Measure ER sales tax took effect October 1, but its proceeds must remain unspent while a legal challenge is pending, the county says. The five-year measure is intended to support health and other services. The county defends its legality; the Libertarian Party’s lawsuit challenges the state law allowing the tax above the usual limit.

Researchers tested a small implant network that uses electrical signals conducted through body tissue, rather than radio, to coordinate sensors and nerve stimulation, Ars Technica reports. Experiments included living rats and animal tissue. The system passes limited amounts of data and has not yet been tested in humans; medical applications remain experimental.

Retired dietitian Anne Daly has delivered meals for Senior Services of Central Illinois for more than four years, Springfield Business Journal reports.

CBS reports that she endorsed routine vaccination and rejected a link between vaccines and autism at her hearing. The full Senate must still vote on confirmation.

Quanta Magazine reports on studies finding that electrical waves across the cortex form ripples and spiral-like patterns associated with different memory tasks. Recordings from epilepsy patients and animal experiments suggest possible roles in coordinating brain activity. Scientists still disagree over whether the waves drive processing or mainly reflect activity underneath.

Former Detroit Lions player Mike Utley visited Mary Free Bed’s adaptive-sports program in Grand Rapids, WGVU reports. His foundation has contributed more than $52,000 since 2021 for 14 pieces of specialized equipment. Staff said access matters because some sports wheelchairs cost $5,000, putting them beyond individual participants’ budgets.

Skydivers who witnessed a plane crash near East Troy, Wisconsin, on Sunday jumped to the scene and helped its occupants, The Guardian reports, citing local interviews and officials. Two had paramedic experience. Three occupants went to hospital and one was treated at the scene; all were expected to survive. Investigators are examining the cause.

Hillsborough, Pasco and Pinellas counties have declared local emergencies amid dengue infections, The Guardian reports. Hillsborough’s September 24 declaration enables officials to seek additional resources for mosquito control. State and federal case totals differ in timing and scope; the reporting includes both travel-related infections and transmission within Florida.

Stanford physician Bryant Lin tells NPR how targeted lung-cancer treatments have extended his life while insurance delays and changing drug responses complicate care. His latest scans showed progression, prompting consideration of another treatment or a trial. The profile illustrates both the promise and limits of personalized medicine; one patient’s experience cannot predict another’s outcome.

Researchers examining 472 Instagram posts under #womenshealth found that 39% directly sold a product or service, while only 7% referred to scientific evidence. In their account published by The Conversation and Phys.org, the authors warn that advertising and health information can blur together. The study did not test whether individual claims were accurate or represent all Instagram content.

Researchers in Poland found that an enzyme from figleaf gourd reduced peanut proteins’ recognition by allergy-related antibodies in laboratory tests, Phys.org reports. Some reactive protein fragments remained. The work has not produced peanuts that are safe for people with peanut allergy; further tests must establish whether the treated material can still trigger allergic reactions.

Actor Billy Gardell described improvements in his health and daily life following bariatric surgery in a recent podcast interview, Fox News reports. He said hiking with his wife and shopping for clothes now feel like meaningful freedoms, while maintaining new eating habits still takes work. His account describes his personal experience.

A Ben-Gurion University team found that cells’ chemical balance regulates a pathway that can help stressed cells survive or trigger their death, according to research summarized by Phys.org. Experiments used human cell lines and cardiac models. The findings suggest possible research targets for cancer and heart injury, not a proven treatment.

Fiji declared an HIV emergency in September as infections rose alongside injected methamphetamine use, NPR reports. Health teams are expanding testing, treatment access and local support, but distance, stigma and limited access to clean injecting equipment remain obstacles. Clinicians warn that reaching people consistently is as important as supplying medicines.

Americans born with injuries linked to thalidomide are urging Congress to acknowledge their experiences and provide financial support, NPR reports. Although the FDA withheld general approval in the early 1960s, the drug reached patients through poorly documented trials. Survivors say that history continues to complicate recognition and care.

Programs delivering meals tailored to patients’ medical needs face uncertain funding as states weigh Medicaid cuts, NPR reports. A Massachusetts study associated the meals with fewer hospital and emergency visits. States and providers are weighing those findings against budget pressure and unresolved federal guidance; the programs have not been uniformly canceled.
