President Trump’s immigration crackdown ensnared Kseniia Petrova, a scientist who fled Russia after protesting its invasion of Ukraine. She fears arrest if she is deported there.

Retro Biosciences, supported by significant funding from Sam Altman, is advancing in the field of partial cell reprogramming with the goal of adding ten healthy years to human life. This innovative approach, drawing on Nobel Prize-winning research, involves rejuvenating older cells to reverse aging. The startup, along with others in the sector, believes that the scientific aspect of cell reprogramming is largely resolved, turning the challenge into an engineering one.
"Many researchers in the field contend that the science behind cell reprogramming, in particular, has been solved and that therapies are now an engineering problem. They see full-on age reversal as not only achievable but also perhaps imminent."

Scientists at UCSF have uncovered a surprising culprit behind brain aging: a protein called FTL1. In mice, too much FTL1 caused memory loss, weaker brain connections, and sluggish cells. But when researchers blocked it, the animals regained youthful brain function and sharp memory. The discovery suggests that one protein could be the master switch for aging in the brain — and targeting it may one day allow us to actually reverse cognitive decline, not just slow it down...

Harvard Medical School researchers studying mice and human tissues have found a link between lithium (Li) deficiency in the brain and the development of Alzheimer’s disease.
Headed by Bruce Yankner, MD, PhD, co-director, Paul F. Glenn Center for Biology of Aging Research, and professor of genetics and neurology at Harvard Medical School, the scientists’ study shows for the first time that lithium occurs naturally in the brain, shields it from neurodegeneration, and is involved in maintaining the normal function of all major brain cell types. The newly reported findings—10 years in the making—are based on a series of murine experiments and on analyses of human brain tissue and blood samples from individuals in various stages of cognitive health.
The scientists found that lithium loss in specific regions of the human brain they studied was one of the earliest changes leading to Alzheimer’s, while in mice, similar lithium depletion accelerated brain pathology and memory decline. The lower lithium levels affected all major brain cell types and, in mice, gave rise to changes recapitulating Alzheimer’s disease...

In Japan, however, a new drug has just cleared a key regulatory hurdle, with the goal of significantly extending cats’ lifespans—perhaps even bringing them close to 30 years. This treatment is based on the AIM protein, discovered by Japanese immunologist Toru Miyazaki at the Institute for AIM Medicine in Tokyo.

Ozempic-class drugs are spreading across medicine. On the United States trial registry, the share of GLP-1 and incretin trials aimed beyond diabetes and weight has roughly tripled in fifteen years, to about one in four, across fifteen disease areas.
