A type of artificial intelligence technique is now being used to develop new drugs and therapies and could perhaps even help to solve aging.
An urgent need for aging biomarkers
There has long been an urgent need in our field to develop increasingly accurate biomarkers of aging so that the efficacy of interventions can be gauged. Deep learning is one of the more recent techniques being applied in the search for aging biomarkers.
Life expectancy rose, and so did the number of years we spend without serious health problems, researchers say.
Libella Gene Therapeutics, LLC (“Libella”) announces a clinical trial in Colombia (South America) using telomere-lengthening gene therapy to reverse aging and possibly cure age-related diseases. Libella has chosen bioaccess™ as its CRO for this trial.
UCLA scientists have discovered a link between a protein and the ability of human blood stem cells to self-renew. In a study published today in the journal Nature, the team reports that activating the protein causes blood stem cells to self-renew at least twelvefold in laboratory conditions.
Multiplying blood stem cells in conditions outside the human body could greatly improve treatment options for blood cancers like leukemia and for many inherited blood diseases.
Dr. Hanna Mikkola, a member of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA and senior author of the study, has studied blood stem cells for more than 20 years.
Accelerating rejuvenation therapies to repair the damage of aging. Berlin, May 21 — 23.
University of Maryland researchers showed sight deprivation changes how groups of neurons work together and alters their sensitivity to different frequencies.
Scientists have known that depriving adult mice of vision can increase the sensitivity of individual neurons in the part of the brain devoted to hearing. New research from biologists at the University of Maryland revealed that sight deprivation also changes the way brain cells interact with one another, altering neuronal networks and shifting the mice’s sensitivity to different frequencies. The research was published in the November 19, 2019 issue of the journal eNeuro.
Some stress at a young age could actually lead to a longer life, new research shows.
University of Michigan researchers have discovered that oxidative stress experienced early in life increases subsequent stress resistance later in life.
Oxidative stress happens when cells produce more oxidants and free radicals than they can deal with. It’s part of the aging process, but can also arise from stressful conditions such as exercise and calorie restriction.

Once, single-cell life claimed sole dominion over the earth. For some three billion years, unfathomable generations of unicellular organisms ate, grew and reproduced among only each other. They evolved into predators and prey, thrived and spread across the primordial waters and land, and formed complex and dynamic ecosystems in every ecological niche on the planet. Around 600 million years ago, some even crossed the threshold into multicellularity.
Today, however, single-cell organisms are synonymous with notions like primitive and simple. Yet, new research suggests that they may be capable of much more than their very distant human cousins might suspect.
In an effort to replicate an experiment conducted over a century ago, systems biologists at Harvard Medical School now present compelling evidence confirming at least one single-cell organism—the strikingly trumpet-shaped Stentor roeselii—exhibits a hierarchy of avoidance behaviors.
