Tracking tiny moving targets. Duke Research blog, July 28, 2020. Kevin Welsher has developed a technique that turns a microscope into a ‘flight tracker’ for molecules, making it possible to follow the paths of viruses and other particles thousands of times smaller than the period at the end of this sentence.

Ultra-black skin allows some fish to lurk unseen. Duke Today, July 16, 2020. Scientists report that at least 16 species of deep-sea fish have evolved ultra-black skin that absorbs more than 99.5% of the light that hits them, making them nearly impossible to pick out from the shadows. Picked by The New York Times, WIRED, Newsweek, Science News, Fox News, NBC News, CBS News, Ars Technica, Popular Science, Gizmodo, CNN and Reuters.

Lights in the eyes for better disguise

Lights in the eyes for better disguise. Duke Today, June 11, 2020. This hatchetfish hides from predators swimming in the shadowy depths below using a clever disguise. Glowing spots on its belly make it nearly invisible against the sunlit waters above. But the fish’s eyes point upward — How does it adjust its underside lights to blend in with the faint light filtering down from above if it can’t see its belly? 

Malaria parasite ticks to its own internal clock

Malaria parasite ticks to its own internal clock. Duke Today, May 14, 2020. Researchers have long known that all of the millions of malaria parasites within an infected person’s body move through their cell cycle at the same time. They multiply in sync inside red blood cells, then burst out in unison every few days. But how the parasites keep time was unclear. Now, a study finds that malaria has its own internal clock that causes thousands of genes to ramp up and down at regular intervals. Picked up by The Scientist, Cosmos Magazine, and Science News.
