Researchers want to harness the parasite that causes toxoplasmosis to ferry drugs, but some question if the risks can be eliminated.

A new study finds that mitochondria in our brain cells frequently fling their DNA into the cells' nucleus, where the mitochondrial DNA integrates into chromosomes, possibly causing harm.

Exploring neural cultures for information processing is rapidly advancing. Organoid
intelligence focuses on developing functional neural organoids to capture physiologically
relevant abilities. An alternative, bioengineered intelligence, is proposed here…

New experiments reveal how astrocytes tune neuronal activity to modulate our mental and emotional states. The results suggest that neuron-only brain models, such as connectomes, leave out a crucial layer of regulation.
