Ageing is one of life’s few certainties. But what if it didn’t have to be? Over the past decade, longevity research has moved from speculative science to a serious, data-driven field — and biotech is leading the charge.
At the heart of this growing movement is a bold question: is ageing inevitable, or can we slow, stop, or even reverse it?
While death remains unavoidable, scientists are increasingly viewing ageing itself as a process — one that may be modifiable. Recent studies suggest that biological ageing is not simply the result of wear and tear, but is driven by specific, trackable mechanisms. These include DNA damage, cellular senescence (where cells stop dividing but don’t die), inflammation, and the shortening of telomeres — the protective caps on our chromosomes.
Researchers and companies around the world are now targeting these pathways. Senolytics, for instance, are drugs designed to clear out senescent cells — the so-called “zombie cells” that accumulate with age and drive inflammation. Early animal studies have shown promising results, with improved tissue function and lifespan extensions in mice.
Then there’s the work on NAD+ boosters, rapamycin, and metformin — compounds that aim to enhance cellular energy or mimic the effects of calorie restriction, which has long been associated with increased lifespan in animals. Human trials are underway, though the science is still young and often contested.
Some researchers, like those at Altos Labs and the SENS Research Foundation, go further — exploring cellular reprogramming and regenerative techniques that might one day rejuvenate entire organs or reset the body’s ageing clock. While these approaches may sound like science fiction, the investment behind them (both intellectual and financial) suggests they’re being taken seriously.
Still, it’s not just about living longer — it’s about living better. The goal is to extend healthspan — the years of life spent in good health — rather than merely delaying death. Ageing research raises profound ethical questions: Who gets access to these treatments? Could they widen health inequalities? And what would a dramatically extended lifespan mean for society?
At NewLimit.cm, we’ll continue to follow the science, the hype, and the ethical dilemmas. Because as we learn more about how we age, we might also learn how to age better — and more fairly.

In the realm of biotechnology, few breakthroughs have generated as much excitement — or ethical debate — as CRISPR. Often described as “genetic scissors”, CRISPR has fundamentally changed how scientists think about editing DNA, offering unprecedented precision and potential across [...]
