Slow, silent 'scream' of epithelial cells detected for first time

It has long been thought that only nerve and heart cells use electric impulses to communicate, while epithelial cells—which compose the linings of our skin, organs and body cavities—are mute, serving mostly as protective ...

Supercomputer simulation shows why beneficial mutations rarely lead to hypermutators in real organisms

In real life, mutants can arise when their DNA changes to give them an advantage over the rest of the population. A team from the University of Michigan has used simulations on the Pittsburgh Supercomputing Center's Neocortex ...

Borrowing nature's blueprint: Scientists replicate bone marrow

Hidden within our bones, marrow sustains life by producing billions of blood cells daily, from oxygen-carrying red cells to immune-boosting white cells. This vital function is often disrupted in cancer patients undergoing ...
