Important developments across research and health technology
Stanford researchers found that removing or blocking the EP2 receptor in tissue-resident macrophages improved inflammation, physical performance, memory-related tests and several organ measures in older mice. Similar patterns involving neutrophils and EP2 activity appeared in human liver-cell data, but no human treatment trial has established that blocking the receptor slows aging in people.
Researchers analyzed near-complete genomes from eight closely related Myotis bat species, whose lifespans vary widely despite similar evolutionary relationships. The study identified selection and cellular-response patterns involving cancer pathways, DNA damage, and defenses against DNA and RNA viruses, but it remains comparative and preclinical research rather than evidence of a human longevity intervention.
A 2026 review examined 565 animal and human studies of six emerging peptides marketed for muscle growth, injury recovery, performance and longevity. Most research was conducted in animals, while human evidence for musculoskeletal benefits was essentially absent; concerns also included weak study designs, conflicts of interest and product-quality risks.
New Research & Technology
A randomized clinical trial from researchers at the University of São Paulo found that increasing daily steps and attending supervised treadmill sessions produced comparable improvements in asthma control, respiratory symptoms, quality of life, and anxiety and depression symptoms among physically inactive adults with moderate-to-severe asthma. The benefits remained four months after the eight-week interventions ended.
Two recent studies in mice link aging-related microglial dysfunction to harmful signaling and report that senotherapeutic approaches can shift white-matter microglia toward a more youthful organization. The findings remain preclinical and do not establish that senolytic treatments improve brain aging in humans.
A Medical Xpress report examines hormesis, the dose-dependent process in which limited stress may activate cellular defenses while stronger or prolonged exposure can cause harm. Research on compounds such as sulforaphane remains uncertain in humans, although stress-response pathways are also being explored in medicines for specific diseases.
Research published in Science Advances found that feeding schedules influenced rhythmic gene activity in mouse liver through the nutrient-sensing pathway mTOR. Blocking mTOR reduced rhythmic gene expression by 50% while leaving the liver’s core circadian clock intact, suggesting that food-related signals operate alongside the intrinsic clock.
A pooled analysis of 12 studies involving 15,925 people in Zimbabwe found that the average age at tuberculosis diagnosis rose between 2000 and 2024. The increase was especially pronounced among women, highlighting the need to account for age-related conditions when diagnosing and treating tuberculosis.
A review in Aging brings together cellular, animal and human research on metformin’s possible effects on aging-related biology. The evidence includes lifespan increases in worms and mice, tissue-aging measures in monkeys and observational human associations—but the researchers emphasize that large, rigorous trials in healthy adults without diabetes are still lacking.
A Science Advances study reports that vesper bats, a group spanning more than 500 species, possess two separate sets of immunoglobulin heavy-chain genes. The unusual arrangement may help explain how these bats host potentially dangerous viruses without becoming seriously ill, although the finding does not fully account for their viral tolerance.
A study of 123 people with idiopathic pulmonary fibrosis found clonal hematopoiesis mutations in 38% of participants. Those with the mutations were more likely to meet the study’s definition of rapid disease progression and experienced a larger 12-month decline in forced vital capacity, but the findings show an association rather than proof that clonal hematopoiesis drives pulmonary fibrosis.
A 2026 iScience paper from Constructor University examines the overlap between ADHD-related attention patterns and creative thinking. The researchers propose that defocused attention may help generate unusual connections, while creative activities could offer structured ways to engage attention-control systems—but the paper does not establish a clinical treatment benefit.
An observational study of 91,292 UK Biobank participants found that each additional daily hour of prolonged, uninterrupted sedentary behavior was associated with a 9% higher risk of cancer death. Replacing an hour of prolonged sitting with light activity was associated with a 12% lower risk, but the study cannot establish that sitting directly caused these outcomes.
A University of Surrey study across three European cities found that older adults with greater natural-light exposure had higher daytime activity and better reported sleep quality. Earlier use of bright-light therapy lamps was also associated with more activity and less disrupted rest–activity rhythms, but the study’s findings reflect real-world light exposure and usage patterns rather than proof of a treatment effect.
A crossover fMRI study of healthy young and older adults found that acute aerobic exercise altered regional brain activity during cognitive tasks. The research also showed that repeating the tasks strongly affected brain-activity efficiency, highlighting the importance of separating exercise effects from practice and habituation.

A mouse study is not a human trial. A company announcement is not clinical proof. An association is not causation. Biohack Report aims to keep those distinctions visible while covering fast-moving research and technology.
