#1. Stem Cell Breakthroughs
In November, Shinya Yamanaka of Kyoto University and molecular biologist James Thomson of the University of Wisconsin reported that they had reprogrammed regular skin cells to behave just like embryonic stem cells. The breakthrough may someday allow scientists to create stem cells without destroying embryos

#4. Hundreds of New Species
…700 new species of organisms — including carnivorous sponges and giant sea spiders — some 2,300 ft. to 19,700 ft. (700 m to 6,000 m) down in the Weddell Sea off Antarctica. Scientists also reported the identification of 24 new species in an isolated area of Suriname, where the exploration for bauxite, which is used to make aluminum, led to the discovery of 12 dung beetles, an ant species, six species of fish and five new frogs, including one with fluorescent purple markings. Other fauna finds include a legless amphibian near Goa, India; 11 new species of plants and animals in central Vietnam’s tropical “green” corridor; a new monkey in Uganda; a sucker-footed bat in Madagascar; a clouded leopard in Sumatra and Borneo, and a sea cucumber off the coast of Taiwan, nicknamed “Little Strawberry.”
