  1. Scientists discovered that some animals can breathe through their butts in emergencies. Cool cool.
  2. Physicists give chances of faster-than-light space travel a boost. “[B]y modifying spacetime within the bubble in a certain way, they could remove the need to use negative energy. This solution, though, does not produce a warp drive that can go faster than light. Independently, Lentz also proposed a solution that does not require negative energy. He used a different geometric approach to solve the equations of General Relativity, and by doing so, he found that a warp drive wouldn’t need to use negative energy. Lentz’s solution would allow the bubble to travel faster than the speed of light.”
  3. Nearly a fifth of earth's surface transformed since 1960.
  4. Researchers create free-floating animated holograms that bring us closer to Star Trek's holodecks.
  5. An artist in Lyon known as “The Pavement Surgeon” repairs the city’s sidewalks using colorful mosaics.
