Cascade sets the stage for superconductivity in magic-angle twisted bilayer graphene
The researchers used scanning tunneling microscopy to observe what happens when they add additional electrons to magic-angle twisted bilayer graphene. They observed a cascade of transitions in the electronic properties, patterns that could help unlock how superconductivity emerge in these materials.

Membrane-proximal F-actin restricts local membrane protrusions and directs cell migration
Cell migration is driven by local membrane protrusion through directed polymerization of F-actin at the front. However, F-actin next to the plasma membrane also tethers the membrane and thus resists outgoing protrusions. Here, we developed a fluorescent reporter to monitor changes in the density of membrane-proximal F-actin (MPA) during membrane protrusion and cell migration. Unlike the total F-a

Dopamine signaling allows neural circuits to generate coordinated behaviors
For a nematode worm, a big lawn of the bacteria that it eats is a great place for it to disperse its eggs so that each hatchling can emerge into a nutritive environment. That's why when a worm speedily roams about a food patch it methodically lays its eggs as it goes. A new study by neuroscientists at MIT's Picower Institute for Learning and Memory investigates this example of action coordination—
