Look At This: The Blood-Brain Barrier, Little Lynx Spiders, and the Fruit Fly Eye, Magnified

First Place: This winning photo depicts the blood-brain barrier, the seal between capillaries and the brain, of a live zebrafish embryo. To produce the image, researchers genetically engineered components of the barrier to fluoresce under a confocal microscope, took a series of photos at 20x magnification, then combined the images to create this one.  This is believed to be the first time the developing blood-brain barrier of a live animal has been captured on film.

What’s the News: A modified antibody can make its way into the brain and target the development of Alzheimer’s-inducing plaques, researchers reported today in two animal studies in Science Translational Medicine. The blood-brain barrier usually keeps drugs and other compounds from entering the brain in large enough quantities to be effective, but these studies show a way to trick the body’s own defenses into letting the drug in, demonstrating that this obstacle to treating Alzheimer’s could potentially be overcome.
