If the history of thermodynamics can teach us anything, it is that modest entropy reversals have not taken us back in time at all. But it is more fun to think otherwise, says guest Jimena Canales.

A Japanese company is proposing a venture to create on-demand meteor showers using small spheres dropped from a satellite. Scientists aren't really keen to the idea.
For two years Mike Hughes worked on a rocket. His goal was to prove the earth was flat. Over the weekend, he got a third of a mile into the air and then fell back to earth. The rocket had a parachute.
Sunita Williams was the second female commander of the International Space Station. Now, she says her new job working with private companies to develop space technologies feels like a new frontier.

Astronaut Andrew Fuestel has been to space three times. He says he has a mild fear of heights, but he can push through it. He's OK after reaching hundreds of miles above the Earth.
Showing science's enchanting side has the almost magical effect of opening new portals to what is possible, says astrophysicist Marcelo Gleiser.

A study shows that not only do astronaut's genes change in space, but they have the potential to remained changed even months after the astronaut is back on Earth.
NASA is building a new space-based laser communication that will allow live, high-definition video from Mars and beyond — something that's not possible with standard radio equipment.

When Einstein, born 139 years ago on Wednesday, came onto the science scene, physics was in crisis. New ideas were badly needed — it was the perfect moment for a trailblazer, says Marcelo Gleiser.
