Prions are basically brain-eating protein zombies, and so far, doctors have no way to cure the diseases they cause. New research that sheds light on how prions access the brain could facilitate earlier detection of prions in the body.

Whether studying the blood vessels in a mouse's ear or the bizarre behavior of a droplet of water, scientists served up some stunning shots this week. There was even beauty to be found in the patches of cells in our own bodies that may serve as a gateway for brain-destroying pathogens.

Capable of blinking at the incomprehensible speed of 90 billion times per second, a new light source represents a key step toward optical computers. These computers could, in theory, run even faster than current computers.

Earthworms are ecosystems engineers, without whom forests and many other parts of our planet would look completely different. Using molecular microscopes, researchers recently uncovered the key to their amazing aptitude for the critical task of recycling plant matter.

Earthlings got new access to something that humans launched into space nearly 40 years ago and also learned about why humans launched kombucha microorganisms into space more recently. Plus, alien auroras, a gorgeous new shot of Earth that spotlights Africa, and more.

Walking on water is already a tough enough task, but jumping from the surface of water presents an even greater challenge. By studying water strider insects, scientists were able to build a tiny robot that can launch itself off this ubiquitous liquid.

Kombucha is all the rage among health nuts and hipsters these days, and apparently scientists have taken interest in the ancient brew, too. ESA has sent samples of the microorganisms that turn tea into Kombucha to space in order to learn more about what forms of life can survive beyond our planet.

Most people living with chlamydia don't even know they have it. The expense of testing for this STD has been an obstacle to early detection and treatment, so researchers developed a lower-cost testing device that attaches to smartphones.

As if anyone needed another reason to love pig fat, scientists are now turning it into cellular lasers. Besides being a lot of fun to play around with, the lasers could help scientists learn about cells in new ways.

Moths’ eyes are exquisitely adapted for seeing in the dark, so they absorb almost all of the light that hits them. This same property may help researchers create solar panels capture more light so that they can generate more energy.

Scientists set up fruit flies to essentially play a virtual reality video game to test whether these insects are self-aware. Their results suggest that the flies were actually aware they were controlling the avatars on the screen.
