Summary: Study finds a link between poor hydration in adults and an increased risk of chronic health conditions and advanced biological aging.

Adults who stay well-hydrated appear to be healthier, develop fewer chronic conditions, such as heart and lung disease, and live longer than those who may not get sufficient fluids, according to a National Institutes of Health study published in eBioMedicine. .

New research in the journal Nature Aging takes a page from the field of renewable energy and shows that genetically engineered mitochondria can convert light energy into chemical energy that cells can use, ultimately extending the life of the roundworm C. elegans. While the prospect of sunlight-charged cells in humans is more science fiction than science, the findings shed light on important mechanisms in the aging process.

“We know that mitochondrial dysfunction is a consequence of aging,” said Andrew Wojtovich, Ph.D., associate professor of Anesthesiology and Perioperative Medicine and Pharmacology & Physiology at the University of Rochester Medical Center and senior author of the study.

“This study found that simply boosting metabolism using light-powered mitochondria gave laboratory worms longer, healthier lives. These findings and new research tools will enable us to further study mitochondria and identify new ways to treat age-related diseases and age healthier.”

Findings underline the importance of a strength-based rather than a deficit-based focus on aging and older adults.

What are the keys to “successful” or optimal aging? A new study followed more than 7,000 middle-aged and older Canadians for approximately three years to identify the factors linked to well-being as we age.

They found that those who were female, married, physically active, and not obese and those who had never smoked, had higher incomes, and who did not have insomnia, heart disease or arthritis, were more likely to maintain excellent health across the study period and less likely to develop disabling cognitive, physical, or emotional problems.

It was only a year ago that ACell’s “miracle powder” was sprinkled on amputated fingers and shown to stimulate the regeneration of fingertips. The world was both awed and skeptical of the powder’s regenerative power, touting that it would revolutionize regenerative medicine or calling it was quack science.

A fingertip is one thing. A thigh, quite another.

Cutting-edge technologies are revealing the intricacies of human ageing and sparking research into drugs to slow it, or even reverse it.

New data shows that several types of the shelled reptiles can slow—and even stop—aging if the environmental conditions are right.

Although we’ve been socialized to accept death as an inevitability, and live our lives knowing that its looming shadow will one day catch up with us, many of us might never really come to terms with it. Throughout our evolution, we’ve come up with ideas, beliefs and theories that attempt to shine a light deep into the cold, dark abyss of death to give ourselves a hope of continued living and everlasting existence. Could we really stop our cells from aging? If you could, would you want to be immortal?

Tardigrades have competition in the realm of microscopic and incredibly sturdy beasties. Like tardigrades, Bdelloid rotifers can also survive drying, freezing, starving, and even low-oxygen conditions. Now, scientists report that they revived some of these rotifers after having been frozen in Siberian permafrost for at least 24,000 years.

The incredible observations are reported in the journal Current Biology. The researchers took samples of permafrost about 3.5 meters (11.5 feet) deep and slowly warmed the sample, which led to the resurrection of several microscopic organisms including these tiny little animals.

“Our report is the hardest proof as of today that multicellular animals could withstand tens of thousands of years in cryptobiosis, the state of almost completely arrested metabolism,” co-author Stas Malavin of the Soil Cryology Laboratory at the Institute of Physicochemical and Biological Problems in Soil Science in Pushchino, Russia, said in a statement.
