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

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 ...

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 ...

The researchers believe the hemifusome works by creating vesicles, tiny bubble-like structures that surround substances in our cells and move them around. “You can think of vesicles like little ...

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 ...

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 ...

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 ...

In a quiet lab at Utrecht University, researchers have built a tool that lets you watch one of life’s most serious crises unfold in real time. Inside every cell, DNA breaks, repairs, and sometimes ...
