The species of jellyfish Turritopsis nutricula could be the only animal in the world that has actually discovered the fountain of eternal youth, as Dr. María Miglietta, of the Smithsonian Tropical Marine Institute (USA) discovered last year.
The cells of our body constantly inform each other of their state of health through an extracellular code, according to a team of researchers from the National Cancer Research Center (CNIO). The malfunction of this communication code, nicknamed Flower, could lead to cancer or early degeneration of tissues and premature aging.
Recent studies in model organisms (flies, mice ...) and in humans have revealed that sensory experiences can have an important impact on health issues, on athletic development and the rate of aging. Specifically, it has been confirmed that worms and fruit flies that are unable to smell or taste live longer.
A study on aging carried out on subjects aged 70 to 90 states that the older we get, the more our differences increase. "We view older people as a homogeneous group, but the reality is that the differences between individuals increase as we age," says Bo G. Eriksson.
The best antidote to cognitive decline and memory loss is learning. According to a study by the University of California, if we cultivate the mental activity of an "eternal learner" our brain produces molecules that keep it young and healthy.
Not all of us age at the same rate as time progresses. The rate of physiological wear and tear and biological age (different from the chronological one shown by our DNI) depend to a great extent on a sequence of genes, as a team of British scientists has just demonstrated. Details are published in the journal Nature Genetics.
A team of American researchers has identified a gene in centuries-old Ashkenazi Jews that prevents cell aging and can extend life by more than 100 years.
A group of Spanish researchers has found that short telomeres are the main source of damage that causes aging in the human body and has described for the first time the genetic alterations that cause this phenomenon.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
