MIT engineers have challenged a core idea in biology by showing that epigenetic memory is not simply binary. Their research reveals cells don’t just lock genes in an “on” or “off” state. Instead, they ...

When cells are healthy, we don't expect them to suddenly change cell types. A skin cell on your hand won't naturally morph into a brain cell, and vice versa. That's thanks to epigenetic memory, which ...

Researchers have unveiled a way to flip genes back on without slicing into the genome, a shift that could make CRISPR far safer and more flexible. Instead of cutting DNA, the new approach scrubs away ...
