AI identifies key gene driving aging in blood stem cells

Stem cells possess the unique ability to self-renew and transform into different types of cells. For example, rare hematopoietic stem cells found in bone marrow can become any type of blood cell.

New lensless imaging method captures clearer images of moving objects

With the rapid development of smartphones, wearable devices, and portable medical diagnostic systems, increasingly stringent requirements have been placed on imaging systems: they are expected to provide clear images while remaining sufficiently compact and lightweight.

Higher BPA exposure tracked with higher estrogen and progesterone in women

Researchers found that higher urinary concentrations of BPA and several phthalate metabolites were associated with higher serum estrogen and progesterone levels in 90 premenopausal women from Iran. The cross-sectional study also identified positive associations for combined chemical exposures, although the authors cautioned that the mixture findings are exploratory and cannot establish causality.

Protein degrader shows strong activity against treatment-resistant blood cancers

A first-in-class therapy to target MYC, one of the most sought-after and difficult targets in cancer biology, showed promise in hard-to-treat blood cancers, according to a new preclinical study from The University of Texas MD Anderson Cancer Center published in Blood.

Researchers link GLP-1 drugs to lower tuberculosis risk in type 2 diabetes

A large retrospective cohort study found that GLP-1 receptor agonist use was associated with a lower risk of tuberculosis in people with type 2 diabetes compared with sulfonylureas, metformin, DPP-4 inhibitors, and SGLT2 inhibitors. The observational findings suggest a possible benefit beyond metabolic control, but the authors emphasize that prospective and mechanistic studies are needed to determine whether GLP-1 therapies themselves reduce TB risk.

Understanding opioid risks can help prevent accidental overdoses

According to numbers calculated from the CDC, approximately 80,000 people died last year from a drug overdose, which represents about 21 deaths per 100,000 residents in the U.S. alone. Overdose deaths are preventable, and in most of the cases we see, they are completely accidental.

Tick-borne alpha-gal syndrome poses potential risks during blood transfusions

A new multi-institute study led by researchers at Dartmouth Health and Geisel School of Medicine at Dartmouth suggests that alpha-gal syndrome, the tick-borne disease that can result in a chronic allergy to meat and animal byproducts, also may complicate certain patients' ability to safely receive a blood plasma or platelet transfusion.

Recipient reputation helps stabilize cooperation in large communities

When one person helps, or refuses to help, another in public, this may change not only the provider's reputation but also the recipient's.

An 11-year study found the same social media pattern again and again

Across 11 annual U.S. surveys involving about 183,000 adults, higher social media use was consistently associated with self-reported depression, with social media ranking among the strongest predictors in machine-learning models. SHAP analyses suggested that social media use became a stronger positive signal for depression at around 150 minutes per day, although the authors stress that this is not an established clinical threshold and requires longitudinal and experimental testing.

Japan vaccinated heavily during COVID-19. Why are so many unsure about vaccinating next time?

A nationwide Japanese survey found that only 53.1% of respondents said they would accept vaccination in a hypothetical future pandemic with COVID-19-like fatality, despite substantially higher previous COVID-19 vaccine uptake. Willingness varied by demographics, perceived disease risk, exposure to misinformation, vaccine characteristics, and practical factors such as cost, evidence, professional recommendations, and accessibility.

Could a daily vinegar drink help with constipation? A small trial offers a clue

A randomized, double-blind trial found that adults with mild constipation who drank a vinegar beverage daily for four weeks had more frequent bowel movements than those receiving placebo. Exploratory findings also suggested earlier improvements in bowel habits, although the small feasibility-based trial requires confirmation in larger and more diverse populations.

Shared protein pathology redefines treatment for multiple neurodegenerative diseases

On the surface, amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD) and limbic-predominant age-related TDP-43 encephalopathy (LATE) might seem like unrelated diseases.

Researchers explore the link between tau levels and depressive symptoms in older people

During typical aging and Alzheimer's disease progression, higher levels of a protein called tau are associated with more depressive symptoms.

Harvard engineers develop smartphone app to aid navigation for people with blindness

For people with blindness or who have low vision, moving around independently is a daily challenge. Harvard researchers have developed a new tool that could help such people navigate more quickly and safely, using nothing but a device they likely already have – a smartphone.
