Flu virus shells could improve delivery of mRNA into cells

Nanoengineers at the University of California San Diego have developed a new and potentially more effective way to deliver messenger RNA (mRNA) into cells. Their approach involves packing mRNA inside nanoparticles that mimic ...

A brief history of minimal surfaces and the ants that love them

Consider a soap bubble. The way it contains the minimal possible surface area is surprisingly efficient. This is not a trivial issue. Mathematicians have been looking for better ways to calculate minimal surfaces for hundreds ...

Illuminating dark matter in human DNA

Researchers at University of California San Diego have produced a single-cell chromatin atlas for the human genome. Chromatin is a complex of DNA and protein found in eukaryotic cells; regions of chromatin at key gene regulatory ...

Size matters for bee 'superorganism' colonies

Scientists have carefully studied the intricacies of how individual organisms live and act together in groups known as biological collectives. In "superorganisms" such as bee colonies, the interactions of the individual members ...
