Scientists reviewed how polyphenol-rich diets in Blue Zones may help people live longer, healthier lives by targeting biological hallmarks of aging. They call for more research to measure polyphenol intake and test its effects on human longevity.

Fish oil supplements, delivering higher EPA doses, significantly reduced the number and procoagulant activity of extracellular vesicles—unlike oily fish. This suggests EPA, not DHA, may drive cardiovascular benefits linked to EV function.

Older adults who limit their sedentary time have lower metabolic syndrome risk, regardless of how active they are or how healthy they eat. Even light movement can support better metabolic health when replacing prolonged sitting.

Body size and excess weight, conventionally assessed using body mass index (BMI), are well-established risk factors for many types of cancer. However, new research to be presented at this year's European Congress on Obesity (ECO 2025, Malaga, Spain, 11-14 May) and published in The Journal of the National Cancer Institute shows that waist circumference (WC) is a stronger risk marker than BMI for developing obesity-related cancers in men, but not women.

A simple urine test could accurately show the recurrence of kidney cancer at an early stage, potentially sparing patients invasive scans and enabling faster access to treatment, new research has shown.

Ulcerative colitis (UC) is a chronic, relapsing disease that causes painful inflammation and ulcers in the colon.

A team of researchers from the Hospital del Mar Research Institute, the Universitat Autònoma de Barcelona and the Pompeu Fabra University has developed a new tool that allows modifying these NK cells to make them immune to the tumor’s defense mechanism.

A depression prevention program that has helped white youth wasn't effective for Black youth, raising concerns about the need for more research to help racially diverse groups, according to new research published by the American Psychological Association.

Excess weight in mid-life is a known risk factor for kidney cancer, but new research indicates that weight patterns throughout life may also affect an individual's likelihood of developing this malignancy.

A technique to improve the precision of prostate cancer surgery means that almost twice as many men preserve their erectile function compared to those undergoing standard surgery, according to results from a clinical trial led by researchers from UCL and UCLH.

A comprehensive study from Karolinska Institutet shows that people with fatty liver disease have almost twice the mortality rate of the general population.

Almost half of people who died with inflammatory bowel disease (IBD) died prematurely, according to a study published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.241117 that used machine learning models to predict death.

The largest analysis to examine the best way to lower levels of 'bad' cholesterol in patients with blocked arteries shows that they should immediately be given a combination of a statin and another drug called ezetimibe, rather than statins alone.

The COVID-19 pandemic has led to increased astigmatism in children, with prolonged screen time and less outdoor activity contributing to eye health issues.

A natural citrus oil from oranges, lemons, and limes is proving highly effective in relieving dry mouth, and when combined with a new lipid formulation, new research suggests it may be effective without significant side effects.

The use of ‘social prescriptions’ to improve children and young people’s wellbeing without medication can strengthen government policy on mental health support, University of Manchester researchers have found.

Researchers confirmed that black-legged ticks (Ixodes scapularis) can trigger alpha-gal syndrome in humans. A 10-year surveillance in Maine identified 23 confirmed cases of the meat allergy outside the lone star tick’s known range.

Researchers used genome sequencing and machine learning to trace the top food sources behind Salmonella infections in the US. Chicken and vegetables emerged as the primary culprits, together accounting for up to 73% of human cases with known sources.

Researchers uncover how probiotics and diet shape the gut microbiome to boost vaccine efficacy, offering new avenues for precision immunization.

A 7-day creatine monohydrate wash-in increased lean body mass in females, especially in the trunk, but adding creatine to resistance training didn’t boost muscle gains beyond training alone. Higher doses or hydration tracking may be needed for long-term effects.
