Rattlesnake repertoire boosts snake-like robot’s skills

Researchers on Thursday said they conducted experiments to learn precisely how sidewinder rattlesnakes are able to climb sandy hills, then applied the reptiles’ repertoire to an existing snake robot so it could do the same thing. (Credit: Chaohui Gong, Reuters/Chaohui Gong)

Physics fundamentals confirmed: Testing Einstein’s time dilation, Quantum Electrodynamics

Results confirm the time dilation predicted for high velocities in the theory of relativity with an accuracy that has never before been achieved. Furthermore, the team provided the first direct proof of a spectral line in highly charged bismuth ions. (Credit: Technische Universität Darmstadt )

Hubble sees influence of a jetstream on a hot, Jupiter-sized exoplanet

The Hubble Space Telescope has imaged light from a hot Jupiter called WASP-43b, detecting temperature differences between the planet's day and night sides. The results suggest that the planet has an eastward jet stream that redistributes some of the heat from its host star, but otherwise there's very little circulation of heat.

A brief history of scientists hunting for time travelers

Making sci-fi teleportation sound less bizarre

If you ever wanted to see a sci-fi plot that expertly applied advanced physical concepts so that with a bit of imagination teleporting a human was not as unbelievable as most of the teleportation scenarios we see in the movies, read this articel. The above is a Cosmic Treadmill, as it appears in Flash #196.
