Human cells are extremely small and tightly packed – at about 20 micrometers across, ...

Vaults are mysterious cellular structures that can be genetically engineered to store information about a cell’s history.

After centuries of mapping the human body in ever-finer detail, scientists are still making discoveries. Here we are, in 2025, and a previously unknown cellular structure that could be vital to our ...

Scientists at Rutgers University–Newark have developed a first-of-its-kind RNA-based nanotechnology that assembles itself inside living human cells and can be programmed to stop propagation of harmful ...

DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave. Researchers have now mapped this hidden architecture in unprecedented detail, showing ...

YAHOO.COM - Sixty years after scientists described the chemical code of life — an interweaving double helix called DNA — researchers have found four-stranded DNA is also lurking in human cells. The ...

Every human born on this planet is not entirely themselves. A tiny fraction of our cells – around one in a million – is actually not our own, but comes from our mothers. That means each of us has ...

In A Nutshell As cells age, they deliberately shrink a major internal structure called the endoplasmic reticulum. This downsizing happens early in adulthood and shifts cells away from protein ...

Instead of killing bacteria, scientists found a way to gently guide gut microbes to produce compounds linked to longevity and healthier aging.
