Researchers believed for decades that genetics influenced only a small part of people's lifespan and that lifestyle was what mattered most, but a new study from the Weizmann Institute in Israel turned this idea upside down and showed that DNA plays a much larger role than anyone imagined in determining who lives longer and who dies sooner.
2+ day, 11+ hour ago (918+ words) The error in previous estimates was not due to incompetence, but to methodological limitations. Older studies on genetics and longevity failed to separate hereditary influences from a factor that scientists call extrinsic mortality: accidents, infections, and environmental events that shorten…...
Few people know, but the most nutritious part of wheat has been discarded for decades to produce white flour, and the "polyamine" spermidine activates cellular cleaning, reduces mortality, and may slow down memory loss.
2+ week, 4+ day ago (885+ words) This discovery repositions a widely ignored byproduct of the food industry as one of the most studied elements in aging science in recent years. Spermidine is a polyamine, an organic molecule produced naturally by the body from amino acids. Its…...
A family has intrigued scientists after registering an overwhelming majority of males for over 200 years, raising the hypothesis of a rare gene linked to the Y chromosome.
1+ mon, 1+ week ago (119+ words) Gut microbiota: study warns how ultra-processed foods and food additives can harm health. Thousands of extremely venomous snakes are turning up dead in neighborhoods across Australia, and the discovery has surprised scientists, who have identified a seemingly common bird as…...
At 103 years old, Dona H'lina lives alone, maintains a routine with books and memory games, has already visited 26 countries, and has become a rare example of aging in Brazil, where people live in single-person households.
1+ mon, 1+ week ago (961+ words) To the At 103 years old, Mrs. H'lina lives alone, organizes her own routine, and keeps her daily life connected to reading and memory games. . The story shown on TV Aparecida gained traction beyond mere human interest because it brings together,…...
Geneticist Steve Horvath says humans could reach 150 years of age and predicts that advances in biological aging and DNA methylation "clocks" will push the limit beyond the record-breaking 122 years already registered.
1+ mon, 2+ week ago (1098+ words) Geneticist Steve Horvath argues that science could push human longevity closer to 150 years, even though the official record is still stuck at 122 years. His bet doesn't stem from empty optimism. but from the progression in biological aging as measured by…...
Schmidtea mediterranea: the animal that regenerates its head, heart, and brain repeatedly, ignores aging, and defies the very idea of "biological death.
3+ mon, 1+ week ago (917+ words) What makes this phenomenon even more extraordinary is the fact that this process can be repeated countless times without clear signs of progressive degeneration. For modern biology, Schmidtea mediterranea is not just a curious animal, but a true living paradox....
Science explains how the world's oldest woman managed to live 30 years beyond average with perfect cholesterol and almost no inflammation.
3+ mon, 2+ week ago (700+ words) Scientists in Spain analyzed biological samples from Maria Branyas, the world's oldest woman, and discovered genetic variants linked to longevity. The study by the Josep Carreras Institute, published in 2025, offers new perspectives on healthy aging. A comprehensive health assessment of…...
