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.
The Contrarian Who Cures Cancers
James P. Allison believed that unleashing the immune system was a way to beat cancer when almost no one else did. A Nobel Prize and a growing list of cancer survivors vindicate him.
Cellular Life, Death and Everything in Between
The discovery that apparently dead cells can sometimes resurrect themselves has researchers exploring how far they can push the point of no return.
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.
Seeing the Beautiful Intelligence of Microbes
Bacterial biofilms and slime molds are more than crude patches of goo. Detailed time-lapse microscopy reveals how they sense and explore their surroundings, communicate with their neighbors and adaptively reshape themselves.
