Scientists compared 51 longevity studies to see which aging biomarkers respond most reliably

Researchers analyzing 51 longitudinal intervention studies found that reliable generation 2+ DNA methylation biomarkers, particularly those predicting mortality or pace of aging, were the most responsive to interventions aimed at longevity or healthspan. Pharmacological and lifestyle interventions produced the strongest biomarker changes, but the authors cautioned that responsiveness does not yet establish these measures as validated surrogate endpoints for slower aging or longer life.

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.

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.

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.

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.

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.

New study makes progress in understanding the mechanisms behind severity of HFpEF

Approximately 3 million people in the United States are living with a condition called heart failure with preserved ejection fraction, or HFpEF.

Study confirms benefits of robotic gastric cancer surgery

Surgery remains the primary curative treatment for gastric cancer, with laparoscopic gastrectomy (LG) established as a standard minimally invasive approach.

Yeast-based nanoparticle vaccine could make annual flu shots obsolete

The world mostly relies on an 80-year-old method for producing flu vaccines from chicken eggs - a slow, costly process that struggles to quickly adapt to new, mutant strains.

Type 2 diabetes incidence increases 10-fold among American youth

Type 2 diabetes has traditionally been a disease that has developed mostly in middle-aged and older adults.

Black Canadians face significant systemic barriers to donating critical blood

Black people in Canada who want to donate blood face barriers to doing so, despite a critical need for specific blood types to treat sickle cell disease, according to new research published in CMAJ.

Type 2 diabetes mechanisms differ significantly based on patient BMI

Research published today in Diabetologia by Amsterdam UMC and the University of Ghana reveals that type 2 diabetes manifests in two fundamentally different ways depending on a patient's body mass index (BMI).

Combined bio-histological score prevents overtreatment in liver transplant patients

Long‑term outcomes after liver transplantation remain hampered by complications linked to intensive immunosuppression—infections, cardiovascular events, kidney dysfunction, and metabolic disorders affect 10% to 40% of recipients.

Semaglutide’s heart benefits may partly involve reduced inflammation

A prespecified analysis of 17,604 SELECT participants found that higher baseline hsCRP was associated with greater risks of major cardiovascular events and death in people with overweight or obesity and established cardiovascular disease. Semaglutide produced rapid and sustained reductions in hsCRP, with changes emerging before substantial weight loss, although the study could not establish whether reduced inflammation directly mediated its cardiovascular benefits.

Disrupted brain-immune signaling may help drive neurodegeneration

A Cell perspective argues that neurodegeneration can emerge from disrupted communication between neural and immune networks, with peripheral immunity, microglia, and gene-regulatory programs all shaping disease processes. The authors propose that restoring immune homeostasis and recalibrating neuroimmune circuits could create new therapeutic and diagnostic opportunities, while emphasizing that many mechanisms remain unresolved in humans.

A two-year diet trial challenges the idea that weight loss is the only result that matters

In the two-year DELISH randomized trial, adults with obesity achieved modest, sustained weight loss with either an adapted Mediterranean-style program or a commercial weight loss program. The Mediterranean-style intervention produced greater improvements in self-reported diet quality, while 24-month weight loss did not materially differ between groups.

A striking immune cell pattern emerges around a person’s 100th birthday

Single-cell immune profiling found that CD4 cytotoxic T lymphocytes become more abundant around age 100, showing stepwise differentiation and substantial clonal expansion. Ex vivo experiments also revealed cytokine plasticity within individual clones, supporting the hypothesis that these cells adapt to persistent antigens during healthy aging, although their direct role in longevity remains unproven.

Scientists uncover tRNA changes driving Chagas parasite transformation

The Chagas disease parasite (Trypanosoma cruzi) undergoes a major transformation throughout its life cycle in order to infect humans and other mammals.

FDA clears innovative blood test for earlier Alzheimer's diagnosis

The U.S. Food and Drug Administration (FDA) has cleared for marketing an innovative blood test with underlying technology invented at Washington University School of Medicine in St. Louis for the early diagnosis of Alzheimer's disease.
