The Space Station Captures a Dragon Capsule
NASA released this photo today with the opening line: The space station has caught a dragon. Unfortunately for "Game of Thrones" fans, and dragon lovers everywhere, this had nothing to do with scaly fire-breathers and everything to do with a "valet" capsule charged with resupplying the International Space Station.
In mid-April, the International Space Station captured the unmanned SpaceXDragon capsule sent to resupply the orbiting outpost. Pictured above, the station's Canadarm2 had just grabbed the commercial spaceship. The Dragon capsule was filled with over 5000 lbs (2260 kilos) of supplies and experiments to be used by the current band of six ISS astronauts who compose Expedition 39, as well as the six astronauts who compose Expedition 40. After docking with the ISS, the Dragon capsule was unloaded and eventually released, splashing down in the Pacific Ocean on May 18. The current Expedition 40 crew, now complete, will apply themselves to many tasks including the deployment of the Napor-mini RSA experiment which will use phased array radar and a small optical telescope to monitor possible emergency situations on the Earth below.

Research shows that the way math is taught in schools and how its conceptualized as a subject is severely impairing American student's ability to learn and understand the material.
- Americans continually score either in the mid- or bottom-tier when it comes to math and science compared to their international peers.
- Students have a fundamental misunderstanding of what math is and what it can do. By viewing it as a language, students and teachers can begin to conceptualize it in easier and more practical ways.
- A lot of mistakes come from worrying too much about rote memorization and speedy problem-solving and from students missing large gaps in a subject that is reliant on learning concepts sequentially.
The surprisingly simple treatment could prove promising for doctors and patients seeking to treat depression without medication.
- A new report shows how cold-water swimming was an effective treatment for a 24-year-old mother.
- The treatment is based on cross-adaptation, a phenomenon where individuals become less sensitive to a stimulus after being exposed to another.
- Getting used to the shock of cold-water swimming could blunt your body's sensitivity to other stressors.
Maybe try counseling first before you try this, married folks.
