Mga malalaking tuklas sa agham sa taong 2011

Pakinggan ang 31-minutong podcast ng Science magazine kung saan binanggit ang mga malalaking tuklas sa agham at teknolohiya sa taong 2011. Ang mga tinatawag na "Breakthroughs of the Year, 2011" ay maaari ding makita dito at nakalista sa baba kalakip ang ilang maiikling paliwanag. Nawa'y maging makabuluhan ang mga tuklas na ito sa pagpapaunlad ng buhay ng sangkatauhan sa susunod at mga susunod pang taon.

  5. Archaic Humans' DNA Lives On

  6. In September 2011, two papers suggested that early Homo sapiens interbred with now-extinct forms of humans in Africa, so that some living Africans carry genes from archaic people, just as all Europeans and Asians recently have been shown to do.
