2月26日，日本大阪大学研究团队在《科学》（Science）在线发表研究论文Reconstitution of sex determination and the testicular niche using mouse pluripotent stem cells，报告他们利用小鼠多能干细胞对睾丸体细胞进行的重建工作。该重建过程重现了性别决定过程，产生了形成生精小管和相邻间质组织的细胞类型，重建的睾丸组织整合了多能干细胞来源的原始生殖细胞，并支持其分化为精原干细胞。这些精原干细胞在移植到睾丸后分化为具有功能的精子，且这些精子成功使卵子受精，并发育成健康且有生育能力的后代。

As mentioned earlier, one approach to solving this problem is to simply make credential theft very, very hard. This is the optimistic approach proposed in Google’s new anonymous credential scheme. Here, credentials will be tied to a key stored within the “secure element” in your phone, which theoretically makes them harder to steal. The problem here is that there are hundreds of millions of phones, and the Secure Element technology in them runs the gamet from “very good” (for high-end, flagship phones) to “modestly garbage” (for the cheap burner Android phone you can buy at Target.) A failure in any of those phones potentially compromises the whole system.，详情可参考谷歌浏览器【最新下载地址】
