aging

Perhaps you’re familiar with the sentiment about how a child's behavior is often transformed into how they act as an adult. A new study finds a connection between some early lifestyle and health choices and later-life concerns.
According to a recent paper, fatigability – how physically tired we feel after specific activities – is a reliable marker of our aging. It can also be used to identify those of us who might be moving towards an eternal nap faster than others.
Energy fuels our growth and maintenance. How exactly that changes, and the relative contributions of exercise and metabolism over time, is difficult to ascertain. A new study provides some answers. It is both dynamic and, as is often the case, nuanced.
Is aging just a matter of miscommunication? Should we have National Oceans, like the National Parks? Is a virus like COVID-19 alive, or is this just the zombie apocalypse? Would the Sierra Club allow genetic modification of a tree to save them?
Aging is a failure to communicate? Should we have national sea parks? COVID-19 is not an equal opportunity disease. If a virus is not truly "alive," is this the zombie apocalypse?
How old is your dog, in dog years? The widely used rule of thumb – human years x 7 – is apparently incorrect. The science behind the new formula tells us something about extrapolation and a lot about how both we, and our canine friends, age. And the Hanks-dog graph is kinda cool, too.
This article is the second in a three-part series that is adapted from an essay written by Dr. Alex Berezow, now archived at Suzzallo Library's Special Collections at the University of Washington. In Part II, he discusses how aging and cancer are two sides of the same biological coin.
Aging, whether you consider it a “natural” biologic process or a disease, is increasingly the subject of scientific investigation that goes beyond epidemiologic studies. Or how diseases impact longevity. Some of the most exciting work comes from studying our metabolism and mapping those changes to specific diseases.
Using an AI algorithm researchers can use electrocardiograms to tell us our gender and age. Have they found a Magic 8-ball of health?
Crickets have just one short season to reproduce. Can they shed light on a theory of aging, which holds: We use so much energy to reproduce, that we have little left over to stop our decline?
If aging is a disease, then what are the signs? And more importantly how do we treat the problem? Surely it must be more than exercise and moderation, right?. The simple process of defining a disease is not as simple as it may seem.
The recent self-death by 104-year old scientist David Goodall brings to the fore a key question: Whether to deem deterioration from advanced aging – beyond having an incurable disease – as another reasonable consideration for euthanasia.
