The brain may form from two independent cell lines: research changes understanding of early nervous system development

Scientists from Stanford University and other American research centers have presented data that challenges one of the basic models of brain development.

Protein restriction may involve a single adaptation program that is associated with healthier aging.

Moderate dietary protein restriction may influence lifespan not through a single “longevity gene” or a single metabolic pathway, but by triggering a holistic physiological program that integrates amino acid recognition by cells, liver function, hormonal signals, the brain, eating behavior, and energy metabolism.

Cells with giant nuclei may mark the earliest sites of cancer formation.

Researchers from Nagoya University have discovered a cellular condition that can occur in the earliest stages of tumor formation – even before full-blown cancer develops.

Gut microbiome linked to accelerated brain aging in young and middle age

Scientists have discovered that signs of accelerated biological aging of the brain can be detected long before old age and that these changes are associated not only with the functioning of neural networks, memory, and mood, but also with the composition of the gut microbiome and the metabolites produced in the gut.

Fat tissue may retain a "memory" of obesity and increase weight regain after weight loss.

Scientists have discovered a molecular mechanism that may help explain why the body remains more susceptible to weight gain after losing weight.

A new study has found a link between disrupted deep sleep and the accumulation of proteins associated with Alzheimer's disease.

Scientists have discovered a possible neurophysiological link between the accumulation of tau protein in the brain, changes in deep sleep, and age-related memory decline.

Very hot drinks linked to more than three times the risk of squamous cell oesophageal cancer: study of nearly a million Britons

A preference for drinking tea, coffee and other hot drinks at very high temperatures has been associated with a sharply increased risk of squamous cell carcinoma of the esophagus.

A drug against pulmonary fibrosis shifted six protein "aging clocks" to a younger date.

An experimental drug, rentosertib, developed to treat idiopathic pulmonary fibrosis, has been associated not only with changes in measures of lung function but also with an unexpected shift in the molecular signature of aging.

Calorie restriction slowed the accumulation of age-related DNA mutations in mice by 30%.

Calorie restriction may have a more profound impact on aging than previously thought. In a new study published September 9, 2026, in the journal Cell, scientists showed that mice fed approximately 30% fewer calories accumulated fewer somatic DNA mutations in cells across several organs.

A handful of nuts a day is associated with a roughly 26% lower risk of hypertension: a new meta-analysis of 143,000 people.

Regular nut consumption may be associated with a significantly lower risk of developing hypertension. A new systematic review and dose-response meta-analysis of eight prospective studies found that people with the highest nut consumption had an average 16% lower risk of newly diagnosed hypertension than those with the lowest nut consumption.
