Lemurs show no age-related inflammation, challenging assumptions about human aging
What can lemurs tell us about inflammation and aging, aka "inflammaging" in humans? That's the question Elaine Guevara, a biological anthropologist who studies the evolution of life history and aging in primates, set out to understand.

Shorter enrollment periods. More paperwork. Higher premiums. The sweeping tax and spending bill pushed by President Donald Trump includes provisions that would not only reshape people's experience with the Affordable Care Act but, according to some policy analysts, also sharply undermine the gains in health insurance coverage associated with it.

The U.S. is having its worst year for measles spread since 1991, with a total of 1,288 cases nationally and another six months to go. But in Gaines County, Texas, which was once the nation's epicenter for measles activity, health officials said they are no longer seeing ongoing measles transmission.

Two new open-source tools are set to make fluorescence lifetime imaging microscopy—or FLIM—faster, simpler and more accessible. Developed by Ph.D. student Sofia Kapsiani in Professor Gabi Kaminski Schierle's Molecular Neuroscience Group, the tools tackle long-standing technical and practical barriers in biomedical imaging.

251. Verbal response time reveals hidden sleepiness in older adults

  • medicalxpress.com language

A new study led by UCLA investigators shows that Verbal Reaction Time (VRT), the amount of time it takes a person to respond verbally, can be a marker of sleepiness in older adults. The study, which measured participants' voice data through standardized cognitive assessments, shows how VRT can passively detect excessive sleepiness, especially among older individuals using sedative medications.

254. Bats replay flight memories in fixed time packets, providing new clues into how memories are stored

  • 5 days ago schedule
  • medicalxpress.com language

Every day, our brain takes countless fleeting experiences—from walks on the beach to presentations at work—and transforms them into long-term memories. How exactly this works remains a mystery, but neuroscientists believe that it involves a phenomenon called neural replay, in which neurons rapidly recreate the same activation sequences that occurred during the original experience. Surprisingly, neural replays can happen both before and after an experience, suggesting they help in both memory storage and also future planning.

Access to nature promotes physical and mental health, and it is vital for children's social and emotional development. Outdoor activities also influence family dynamics, helping to reduce stress and encourage connections.

256. Breathing dirty air may raise the risk of a common brain tumor

  • 5 days ago schedule
  • medicalxpress.com language

People exposed to higher levels of air pollution may be more likely to develop meningioma, a typically noncancerous brain tumor, according to a large study published in Neurology. This common type of brain tumor forms in the lining of the brain and spinal cord. The findings do not prove that air pollution causes meningioma; they only show a link between the two.

257. Chromosomal abnormality scores unlock path to personalized immunotherapy

  • 5 days ago schedule
  • medicalxpress.com language

In a newly published article in Nature Genetics, researchers from the University of Chicago have identified tumor aneuploidy—an imbalance in the number of chromosomes—as a powerful biomarker associated with resistance to immunotherapy across cancer types. The study emphasizes how combining immunotherapy with radiation may help overcome the issue of therapy resistance, offering a new framework for predicting treatment response and personalizing cancer therapy.
