New building blocks of cell communication: How an invisible 'cap' could control electrical synapses

When two cells "talk" to each other, they often do so through tiny channels called electrical synapses. Unlike chemical ...

Stem cell organoids mimic aspects of early limb development

Scientists at EPFL have created a scalable 3D organoid model that captures key features of early limb development, revealing ...

Genome Maintains 3D Structure During Cell Division, Contrary to Long-Held Belief

Before cells can divide by mitosis, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material. Scientists have until now ...

Scientists capture first detailed look inside droplet-like structures of compacted DNA

Inside human cells, biology has pulled off the ultimate packing job, figuring out how to fit six feet of DNA into a nucleus ...

Scientists think we could ‘recharge’ our cells—and rewind the aging clock

Mitochondria can lose power like batteries, but they can potentially be regenerated—a promising development than can be used in future treatments.

Where the heck did all those structures inside complex cells come from?

In short, Gould, Garg, and Martin’s hypothesis explains why endomembrane compartments evolved: to solve problems created by the new guest. But it doesn’t fully explain how the alphaproteobacterium got ...

Scientists Create Human Embryo-Like Structures with Stem Cells

Scientists have created synthetic blobs that resemble a 14-day-old human embryo for the first time, meaning they can study embryo development beyond a particularly tricky period of pregnancy.

Scientists reverse aging in blood stem cells by targeting lysosomal dysfunction

Researchers at the Icahn School of Medicine at Mount Sinai have discovered how to reverse aging in blood-forming stem cells in mice by correcting defects in the stem cell's lysosomes. The breakthrough ...
