“The white sea urchin (Lytechinus pictus) is found below the tide line,” writes marine biology graduate student Julia Notar in her submission. “I study how these animals see, and what they can see. They usually live in flat, sandy areas, where there aren't many places to hide from fish predators. Different species of sea urchins, which live in rocky areas, usually hide from fish in dark crevices in, between, or under rocks. Those urchins can use their blurry, but still useful vision to find those hiding spots. Does this species, which doesn't live in an environment with many hiding spots, do the same thing?”

This is an illustration, not a picture, of a virus, because viruses are super small. But a new "VirusCam" promises to be able to see and track individual viruses, potentially leading to breakthroughs for human health.

"VirusCam" Can Watch Individual Viruses to (Someday) Keep You From Getting Sick

Viruses are tiny and hard to see, but a new microscope can track them individually to try to better prevent disease

The image shows a 6 mm long, 12.5 day old mouse embryo obtained with the Mesolens. The inset shows a blow-up of the eye region revealing the individual cell nuclei. It is possible to identify fine structures throughout the embryo such as the developing heart muscle fibers and fine details in the eye such as the corneal endothelium using the Mesolens.
