On Waste Plastics at Sea, She Finds Unique Microbial Multitudes
Maria-Luiza Pedrotti is illuminating the unseen worlds of plastic-eating bacteria that teem in massive ocean garbage patches.
Slime Molds Remember — but Do They Learn?
Evidence mounts that organisms without nervous systems can in some sense learn and solve problems, but researchers disagree about whether this is “primitive cognition.”
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.
Simpler Math Tames the Complexity of Microbe Networks
The dizzying network of interactions within microbe communities can defy analysis. But a new approach simplifies the math and makes progress possible.
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.
Bacteria Use Brainlike Bursts of Electricity to Communicate
With electrical signals, simple cells organize themselves into complex societies and negotiate with other colonies.
Building Codes for Bacterial Cities
Hydrodynamics and competition guide the architectural design of biofilm fortresses.
Swirling Bacteria Linked to the Physics of Phase Transitions
The new experiments suggest that simple models can explain the behavior of thousands of interacting organisms.
Why Some Genetic Miscues Are Helpful
A new look at the reasons why organisms missing pairs of genes sometimes do much better than normal.
