How dividing cells avoid setting off false virus alarms

Credit: CC0 Public Domain One feature of cell division has long puzzled scientists. The nucleus briefly disappears, leaving the cell's DNA exposed. Normally, bare DNA indicates a viral infection and triggers enzymatic alarms that alert ....

A tiny instrument to measure the faintest magnetic fields

(a) A conventional superconducting quantum interference device (SQUID) consists of a superconducting ring interrupted at two points by weak links (in this case a graphene layer). (b) The new SQUID is made up of a ....

Lab-grown earthquakes reveal the frictional forces acting beneath our feet

High-speed cameras and dynamic digital image correlation reveal the shifting motions and forces along a simulated thrust-fault earthquake. Arrows indicate the direction and, by their length, strength of the ground velocity and the fault slip ....
