Researchers develop primate stem cells from unfertilized embryo
... including heart and brain cells -- from embryonic monkey stem cells through a process called parthenogenesis. The researchers reported that they had generated a "pluripotent" stem cell line that they called cyno-1 (so named for the species of monkey). From that cell line, they already have produced brain ...Gene duplication adapts to changing environment
...researchers found that the douc langur, a colobine monkey from Asia, has two---one encodes RNASE1, and its duplicate encodes a new enzyme, which they dubbed RNASE1B. The duplication occurred about 4 million years ago, after colobines split off from the other Old World monkeys, Zhang's analysis showed.
