NASA’s climate change satellite launches to watch Earth breathe

NASA's latest rocket has blasted off successfully, beginning a new and potentially controversial study into carbon dioxide gas in Earth's atmosphere which could have broad implications on climate change research. The Orbiting Carbon Observatory-2 (OCO-2) promises hitherto-unmatched precision measurements from 438 miles above our planet, carrying instruments that NASA says are capable of counting individual molecules.

Facebook Mood Study: The Facts

Facebook Mood Study: The Facts

Earlier this month it was made apparent that a study was conducted on Facebook users by the Facebook, Inc. Core Data Science Team. A total of 689,003 Facebook users were "exposed to emotional expressions in their News Feed" according to the study, testing whether "emotional contagion" is able to occur without direct interaction between people. Turns out it is, indeed possible to change people’s emotions without nonverbal cues.

The Saturday flight took place in Hawaii, with the distinctive saucer-shaped craft being dropped 120,000 feet above the Pacific Ocean and then taking thirty minutes to descend into the waves.

Gliese 832c possibly habitable but has extreme seasons

Don't get your hopes up yet for galactic colonization, but a new planet has just been added to the Habitable Exoplanets Catalog. Gliese 832 c of the Gliese 832 star system is theorized to have temperatures close to Earth's, making it possibly habitable except for one glaring flaw: it has large seasonal shifts.

Facebook is, unsurprisingly, embroiled in yet another scandal. Surprisingly, it isn't directly related to privacy but comes quite close. The social networking giant has been revealed to have manipulated their news feed ever so slightly in order to see the effects on the moods of its users. Sounds almost harmless until you learn that the findings were recently published in a Proceedings of the National Academy of Sciences (PNAS) paper.

White dwarf star could be Earth-sized diamond

If people here on earth already fight over diamonds, imagine what they would do over one the size of the planet itself. That might actually be what David Kaplan and astronomers from University of Wisconsin-Milwaukee have discovered, a dead star so cold that it might have crystalized over to become a literal gem in the sky.
