Scientists uncover shared gene signatures that reveal how mammals age

Researchers mapped more than 11,000 transcriptomes across mice, rats, macaques, and humans, revealing conserved molecular signatures of aging and mortality across tissues, species, and cell types. The study developed interpretable transcriptomic clocks that track age, mortality-related molecular change, chronic disease signals and responses to lifespan-altering interventions.

Gut microbes may reveal who is at risk of type 2 diabetes years before diagnosis

A large Swedish prospective cohort study found that specific gut microbial species and metabolic pathways measured years before diagnosis were associated with future type 2 diabetes risk. The findings suggest that gut microbiome composition and functional potential may help explain T2D development, but replication is needed before clinical use.

Advanced tau imaging improves early Alzheimer’s disease detection accuracy

A new brain imaging test can detect a key hallmark of Alzheimer's disease before symptoms appear and earlier than the method currently used in clinical practice in the United States and Europe, report University of Pittsburgh School of Medicine researchers today in The Lancet.

High-puff disposable vapes may accumulate harmful toxic chemicals

A University of California, Riverside-led study has found that heavily used high-puff electronic cigarettes may contain higher levels of harmful chemicals than fresh e-cigarettes, raising concerns about potential health risks for users.

Ocrelizumab slows disability progression in advanced progressive multiple sclerosis

A major international phase III clinical trial, led by Queen Mary University of London, has found that ocrelizumab – a medication already prescribed to some patients with MS – significantly slows disability progression in people with primary progressive multiple sclerosis (PPMS), including older patients and those with more advanced disease who are wheelchair users.

UCLA researchers identify brain circuit controlling memory organization

When a person has a new experience, their brain faces a subtle but critical decision: should this experience be categorized with other stored memories, or should it be filed away as its own new memory? Getting it right allows the brain to help people navigate the world.

Blood biomarkers may detect Alzheimer’s risk before symptoms appear

For the first time, researchers found blood biomarkers for Alzheimer's disease that correlated with minor cognitive differences in midlife adults who did not have dementia.

Gut changes linger years after polyp removal and may signal colorectal cancer risk

Researchers found that women who had undergone colorectal adenoma resection still showed gut microbiome and fecal metabolome alterations an average of about 12 years later. These persistent changes partly resembled colorectal cancer-associated patterns, suggesting that the host-microbiome axis may remain altered along the adenoma-cancer continuum.

Mental health challenges linked to hidden online harms among youth

A new study from researchers at the Child Mind Institute finds that negative online experiences are common among children and adolescents with mental health and neurodevelopmental conditions, and that most incidents are not reported through platform reporting tools.

Smokers undergoing lung cancer surgery face higher complication risks

Researchers at the University of Cincinnati College of Medicine have found that patients who continue to smoke ahead of lung cancer surgery have a higher risk of pulmonary complications, but their short-term mortality rate is similar to patients who were able to stop smoking before surgery.
