The cave loaches were first discovered by a group of cave divers exploring the Danube–Aach system, a subterranean water system that formed over 400,000 years ago in present day Germany. Genetic studies of the fish and geological history of the area indicate that the cave loach arose within the past 20,000 years.

While most spiders weave intricate webs to capture their prey, the gladiator spider uses a more hands-on approach. It meticulously weaves a quadratic net, which is very elastic, and although not very sticky, it does well to entangle whiskers, bristles, and hairs. When it’s ready to pounce, the spider waits for the perfect moment before pouncing downwards while extending the net. The gladiator spider has developed very sensitive eyes that allow it to hunt in near darkness.

In a faint, small galaxy about 10.7 billion light years from Earth, a mysterious flash of X-rays was recently detected by the Chandra X-ray Observatory. It was first noticed when the flashes became at least 1,000 times brighter in just a few hours. After about a day, the source had faded completely below the sensitivity of Chandra. Several leading theories fall short of fully explaining the phenomenon and more observations are needed to figure this one out.
