Cells Blaze Their Own Trails to Navigate Through the Body
With self-generated gradients of chemicals and physical tension, cells in the body steer themselves to vital destinations.
Biologists Rethink the Logic Behind Cells’ Molecular Signals
The molecular signaling systems of complex cells are nothing like simple electronic circuits. The logic governing their operation is riotously complex — but it has advantages.
‘Social’ Mitochondria, Whispering Between Cells, Influence Health
Mitochondria appear to communicate and cooperate with one another, both within and between cells. Biologists are only just beginning to understand how and why.
Mitochondria May Hold Keys to Anxiety and Mental Health
Research hints that the energy-generating organelles of cells may play a surprisingly pivotal role in mediating anxiety and depression.
Cells Talk and Help One Another via Tiny Tube Networks
Long-overlooked “tunneling nanotubes” and other bridges between cells act as conduits for sharing RNA, proteins or even whole organelles.
Brainless Embryos Suggest Bioelectricity Guides Growth
Researchers are building a case that long before the nervous system works, the brain sends crucial bioelectric signals to guide the growth of embryonic tissues.
