Most rod-shaped bacteria divide by splitting into two around the middle after their DNA has replicated safely and segregated to opposite ends of the cell. This seemingly simple process actually demands tight and precise coordination, ...

A ripe apple falling from a tree has inspired Sir Isaac Newton to formulate a theory that describes the motion of objects subject to a force. Newton's equations of motion tell us that a moving body keeps on moving on a straight ...

(Phys.org)—Physicists have demonstrated Bell correlations in the largest physical system to date—an ensemble of half a million atoms at an ultracold temperature of 25 µK. The presence of Bell correlations indicates that ...
Expanding the potential of gold nanoparticles for a range of uses requires methods to stabilize the clusters and control their size. Researchers at KAUST reveal how simple organic citrate ions, derived from readily available ...

Time crystals may sound like something from science fiction, having more to do with time travel or Dr. Who. These strange materials—in which atoms and molecules are arranged across space and time—are in fact quite real, ...

Physicists want to use ultracold gases in space to measure the Earth's gravitational field, to subject Einstein's Equivalence Principle to an accurate test, and also to detect gravitational waves. The first flight in a sounding ...
