European Intermediate eXperimental Vehicle (IXV) was launched on a Vega rocket from Europe’s Spaceport in French Guiana on Feb. 11.

The spacecraft was then released into a suborbital trajectory, and flew autonomously, reentering and splashing down into the Pacific Ocean after 100 minutes. This crucial test for ESA has exceeded scientists’ expectations as IXV behaved flawlessly, responding to conditions so precisely and promptly.

Soft drinks are loaded with sugar because they need to be sweet. But why is sweetness the fundamental consideration?

Some candies are sour and people love them. When did we become so polarized about sweet and salty? Some of it is just culture and so it would take time to adjust. A friend of mine moved to the U.S. from Korea and an early comment was, 'There is so much cheese' but Americans don't realize that we have dairy everywhere. 'Soft' drinks as we know them were created so merchants could sell something on Sundays, when 'hard' drinks were not allowed. Because the market was also kids they were made sweet.
During the launch of the latest Soyuz to the space station Scott Kelly and Mikhail Kornienko calmly looked at an iPad.  Other than the cramped confines of the Soyuz capsule, and their space suits, they looked like business men discussing their presentation while flying economy class.  



This is the first of a series of lessons about chemical bonds.  The purpose of publishing this through Science 2.0 is to solicit comments and suggestions prior to a formal proposal for its use in the general chemistry classes particularly, in the junior high school science.  I will appreciate if one can point out any oversimplification that may lead to misconceptions.  Another purpose is for this to be used as a review material for non-chemistry major students enrolled in general chemistry.
Chemical bonds is one of the topics assigned to Grade 9 Science by the Philippine Department of Education (DepEd).

Not every member of a social network is human. We are being watched, even played with by giants such as Facebook which openly admitted running social experiments.


Just like the Pharaoh Cheops, who ruled the ancient Old Kingdom of Egypt, ESA’s CHaracterising ExOPlanet Satellite (CHEOPS) could be someday ruling in the field of exoplanet hunting.
My wife and I were in an airport newsstand. I was looking through the magazines to find something to read on the flight when I saw something that didn't make sense. Quite confused, I had to blink a few times to make sure I was seeing what I was seeing. My wife was a few yards away in the store looking at some knickknacks, so I had to say this loud enough for her to hear: "Tabby, I think I've accidentally stumbled into an alternate universe because Paris Hilton is on the cover of National Geographic:

Last Friday and Saturday, the 2015 Synopsys Sac STEM Fair was held at Folsom High School.

I moved here from the football town of Pittsburgh and one thing everyone in football fandom knows about football towns is that for 8 or more days during football season, the parking lots at stadiums are jam-packed with "tailgating" fans, even if they don't have tickets to the actual game. Tailgating is named such because in its earliest form it was just driving a truck up before the game and putting down the tailgate and sitting on it and having a refreshment. Then it became about bringing a grill and cooking some food, then suddenly it became a football event in itself.
