Here’s what you’ll learn when you read this story: Scientists were able to 3D-print different microstructures inside live cells, including a delightfully tiny micro-elephant. The team also printed ...

A largely overlooked structure inside our cells may play a crucial role in how the brain forms, offering new insight into ...

Since each cell has about six feet of DNA packed inside it, it must be folded up tightly to fit. This folding not only saves space -- it also controls which genes are active or inactive. But when the ...

Microglia, the immune cells that protect the brain, are thought to maintain a healthy brain environment by removing unwanted ...

DNA isn't just a long string of genetic code, but an intricate 3D structure folded inside each cell. That means the tools used to study DNA need to be just as sophisticated-able to read not only the ...

Researchers at the Francis Crick Institute have shown that the 'pacemaker' controlling yeast cell division lies inside the nucleus rather than outside it, as previously thought. Having the pacemaker ...

Ever wanted to ride a rollercoaster through the inside of a bacterial cell? Now you can, at least in Minecraft. Researchers from the University of Illinois at Urbana-Champaign created CraftCells – ...

It started as a joke. How do you put an elephant in a refrigerator? You open the door and put it in. So, how do you put in a giraffe? You open the door, take out the elephant, and put the giraffe in.
