Ketogenic diet reverses obesity-linked biological aging by over 6 years

Obesity speeds up biological aging at the molecular level, but this study finds that a very-low-calorie ketogenic diet (VLCKD) can significantly reverse this effect.

UZH researchers develop decoy molecules to restore immune defense

An immune system defect makes affected individuals vulnerable to severe viral diseases such as influenza or COVID-19. It is caused by the body's own antibodies, which inhibit important defense proteins known as type I interferons.

What do Blue Zone diets have in common? Polyphenols that may slow aging

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 beat oily fish at reducing harmful blood vesicles

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.

Skipping exercise? Just sitting less may still improve your metabolic health

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.

Waist circumference identified as a stronger cancer risk marker in men

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.

Simple urine test may spare kidney cancer patients from invasive scans

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.
