Cells

A landmark study is due to start in the coming months, and if successful it could ultimately revive our immune system in older age and even treat chronic illnesses like autoimmune disease. The Phase 1 trial is aiming to rejuvenate senescent T cells.

Scientists have not just found a new way that aging cells drive inflammation, but have also blocked it from happening with an existing FDA-approved drug. This opens the door to an entirely new way to shield the body from age-related health decline.

Anti-aging peptides have become one of the most talked-about experimental treatments in this emerging area of science – and one in particular, GHK-Cu, has shot to fame this year. So, what is it exactly? We separate the reality from the hype.

It came from the depths. A severed foot that refused to die, regenerating in an act of survival unlike anything we’ve ever seen. It could be a great opening to a horror novel, but this discovery of a “real-life zombie” is no work of fiction.

Scientists have identified a new way to supercharge obesity drug semaglutide by targeting key neurons. It could dramatically boost GLP-1 weight-loss power and prevent the dreaded plateaus that not even this "wonder drug" has been able to circumvent.

For two decades giant viruses have unsettled one of biology’s most fundamental boundaries forcing scientists to rethink how cellular complexity emerged. A newly discovered giant virus sharpens that debate, offering clues about how a key feature of most complex life may have evolved.

After a century of false starts, scientists believe they have found a way to make cells burn more energy without the dangerous side effects – and it could be a breakthrough that reshapes weight-loss and anti-aging medicine as we know it.

In a breakthrough study, scientists built a new kind of "super microscope" letting them zoom in on living human cells with incredible detail. This offers a new real time insight into how the flu virus tries to slip inside cells.

Scientists have found the clearest evidence yet that Epstein-Barr virus – which nearly all of us carry for life – is directly responsible for hijacking our immune system's cells to cause lupus, a chronic disease that affects up to a million Americans.

Even in death, cells leave a trace. Scientists have discovered a microscopic “Footprint of Death” that not only helps the immune system clean up but can also give viruses a new way to spread infection.

What naked mole-rats lack in the looks department they make up for it in longevity, living healthily for nearly four decades. Now, scientists have found just how they repair their DNA – and it has the potential to be harnessed by humans to do the same.

Scientists have taken the most detailed look yet at the biology of a record-breaking woman who lived 117 years and 168 days free of cancer, cardiovascular disease and dementia. And many things they discovered could help us achieve our own longevity.
