How did the zebrafish get its stripes? Researchers are one step closer to finding out

Although zebrafish are much smaller and less famous than their terrestrial namesakes, the tiny fish possess a unique ability: They can rapidly change the color of their characteristic stripes from blue to yellow when they're ...

New approach uses 'cloaked' proteins to deliver cancer-killing therapeutics into cells

An interdisciplinary collaboration has designed a way to "cloak" proteins so that they can be captured by lipid nanoparticles, which are akin to tiny bubbles of fat. These bubbles are small enough to sneak their hidden cargo ...
