One of the world's most extensive birth cohorts is now entering later adulthood. At the University of Oulu in Finland, the Northern Finland Birth Cohort 1966 (NFBC1966) is launching a major new follow-up combining decades of biological, social, and environmental data with modern digital health tools to examine how lifelong exposures and the genome shape health and aging.

Physical rehabilitation and symptom management still remain the mainstay of treatment for stroke, as clot removal or dissolution is effective only within a narrow time frame after the stroke. After that, many patients are left with long-term problems like difficulty walking, speaking, and memory decline.

Recently, there has been convergence of thought by researchers in the fields of memory, perception, and neurology that the same neural circuitry that produces conscious memory of the past not only produces predictions of the future, but also conscious perception of the present.

"You're not crazy," the chatbot reassured the young woman. "You're at the edge of something."

Cancer and Alzheimer's are two of the most common chronic diseases associated with aging. For years, doctors have known about a curious aspect of these two conditions: people who survive cancers are significantly less likely to develop Alzheimer's. While this link has been observed in the data for some time, the biological reasons for it have remained a mystery. Now, a new study published in the journal Cell has discovered a possible explanation.

Lung cancer varies widely from patient to patient, and that diversity makes it hard to find effective treatments. Researchers at the Berlin Institute of Health at Charité (BIH) have developed a method to evaluate multiple therapeutic approaches on patient-derived "tumoroids"—miniature tumors grown from tissue removed during surgery at Charité.

Splinters are everyday injuries commonly involving a small shard of wood, glass, metal, plastic or a thorn that becomes embedded in the skin and the soft tissue underneath. The outer skin layer, known as the epidermis, has a high level of pain receptors. The layer just underneath, called the dermis, has even more of them, potentially making such injuries very painful.

Women with cervical cancer who experience significant muscle loss during treatment die at six times the rate of those who maintain muscle mass, according to an international review of 23 studies involving more than 4,000 patients.

By 2050, an estimated 50% of the world's population will be nearsighted, and nearly a billion people will suffer from severe myopia. To understand this alarming trend, Langis Michaud is doing a thorough review of medical literature on the subject.

Two recent studies from the University of California, Riverside, published in the same issue of Gut Microbes highlight the role of a gene called PTPN2 in protecting the gut from harmful bacteria linked to inflammatory bowel disease (IBD).
