Flippable DNA switches help bacteria resist antibiotics and are more common than thought

Invertons — bits of regulatory DNA that can flip between “on” and “off” positions — let bacteria adapt to their surroundings and are widespread. Bacteria have a number of well-known tricks available to them to adapt to changing environments, such as mutation and sharing snippets of DNA with each other….

Mapping the brain, cell by cell

Technique for preserving tissue allows researchers to create maps of neural circuits with single-cell resolution. MIT chemical engineers and neuroscientists have devised a new way to preserve biological tissue, allowing them to visualize proteins, DNA, and other molecules within cells, and to map the connections between neurons. The researchers showed…
