NASA Ames Reproduces the Building Blocks of Life in Laboratory
NASA scientists studying the origin of life have reproduced uracil, cytosine, and thymine, three key components of our hereditary material, in the laboratory. They discovered that an ice sample containing pyrimidine exposed to ultraviolet radiation under space-like conditions produces these essential ingredients of life. – See more at: http://www.astrobio.net/topic/origins/origin-and-evolution-of-life/nasa-ames-reproduces-building-blocks-life-laboratory/#sthash.7JIfVL47.dpuf

The EMBERS Project Can Predict the Future With Twitter
Virginia Tech (VT) offers a glimpse into just how much “big data” has changed the game by magnifying the U.S. intelligence community’s ability to forecast—with phenomenal accuracy—human behavior on a global scale by scouring Twitter, YouTube, Wikipedia, Tumblr, Tor, Facebook and more. VT is using algorithms and a variety of advanced tools to sort through dense and complex information for patterns in the chaos—patterns that frequently point to events before they happen, such as civil uprisings, disease outbreaks, humanitarian crises, mass migrations, protests, riots, political routs, even violence.

Homo generoak uste baino sustrai sakonagoak ditu
Etiopian aurkitutako hominino baten fosilak 2,8 milioi urte inguru dituela kalkulatu dute. Inoiz aurkitu den Homo generoko fosilik zaharrena da, eta milioi-erdi urte atzeratzen du Homo generoaren jatorria. Hain zuzen ere, genero hori uste baino lehenagotik datorrela ondorioztatu dute aldi berean argitaratu den beste ikerketa batean ere, Homo habilisen aspaldiko fosil bat ordenagailu bidez berregin ondoren.
