2013 was a great yer for the guys at SciShow, and for me too. I learned a lot, given the fact that I have another sci&tech blog in Romanian, tehnocultura.ro.
2013 brought us the Higgs Bosson, not such a big surprise after all, and then we found out that there is water on Mars and that it may have been habitable and, lastly, the scientists discovered an 400 000 years old human skeleton. It seems that it was a relative of Neandertal.
More info in the video from above.
What did 2013 brought you?
