- First migration from Africa less than 95,000 years ago: Ancient hunter-gatherer DNA challenges theory of early out-of-Africa migrations
- For the first time Iberian lynx embryos are collected and preserved
- In triplicate, genes make maize tolerant to toxic soil
| Posted: 22 Mar 2013 08:48 AM PDT Recent measurements of the rate at which children show DNA changes not seen in their parents -- the "mutation rate" -- have challenged views about major dates in human evolution. In particular these measurements have made geneticists think again about key dates in human evolution, like when modern non-Africans split from modern Africans. The recent measurements push back the best estimates of these dates by up to a factor of two. Now, however scientists present results that point again to the more recent dates. |
| For the first time Iberian lynx embryos are collected and preserved Posted: 22 Mar 2013 06:07 AM PDT A pioneering procedure in felines allows the collection of biological material from Iberian lynx females before castration. The preserved biological material of the lynxes will be used in future conservation breeding programs. |
| In triplicate, genes make maize tolerant to toxic soil Posted: 20 Mar 2013 10:33 AM PDT Rendering some of the world's toxic soils far less unfriendly, researchers are learning to grow stress-tolerant crops on formerly non-farmable land. |
