Submission + - Humans Born in Space May Be Doomed to Gravity Sickness ( 1

NASA first started sending jellyfish to space aboard the Columbia space shuttle during the early '90s to test how space flight would affect their development. Under the fantastic headline "Space-Born Jellyfish Hate Life On Earth" Popular Science notes that jellyfish babies, born in microgravity environments, "have to deal with massive vertigo on Earth after spending their first few days in space". There's a possibility for future generations of space-born human children, who might never be acclimatised to a terrestrial environment, and in fact could be incapacitated by gravity forces approaching "normal". Jellyfish tell up from down through calcium sulfate crystals that ring the bottom edge of their mushroom-like bodies. Humans sense gravity and acceleration through calcium crystals in the inner ear — similar to jellyfish — moving sensitive hair cells that signal our brains on direction of gravitation.


Submission + - Russian City Ever Watchful Against Being Sucked Into Earth (

Jeremiah Cornelius writes: Dmitry Rybolovlev bought the most expensive apartment ever sold in New York City — the $88 million penthouse at 15 Central Park West — did much for local real estate values. But in Berezniki, the mining city where he made his fortune, properties have literally been plunging. "Imagine putting a sugar cube in a cup of tea," Mikhail A. Permyakov, the chief land surveyor for Uralkali, the company that owns the mine. "That is what happened under Berezniki." Berezniki is afflicted by sinkholes, hundreds of feet deep that can open at a moment's notice. So grave is the danger that the entire city is under 24-hour video surveillance. In 2008 a government commission cleared Mr. Rybolovlev of wrongdoing, blaming past unsafe practices for the sinkholes. A senior official close to Prime Minister Vladimir V. Putin says that Mr. Rybolovlev bears some responsibility, even though he sold the mine after the occurrence of the first great openings.

Some people have a great ambition: to build something that will last, at least until they've finished building it.
