Fully Functional Bioengineered Tooth Grown In a Mouse: “A couple of weeks back the Wall Street Journal reported on the first organ grown in vivo from stem cells — a tooth in the mouth of a mouse. Reader cdrpsab spotted the news on the MedGadget blog; the research had been reported earlier in the PNAS. From the WSJ: ‘The researchers at the Tokyo University of Science created a set of cells that contained genetic instructions to build a tooth, and then implanted this tooth germ into the mouses empty tooth socket. The tooth grew out of the socket and through the gums, as a natural tooth would. Once the engineered tooth matured, after 11 weeks, it had a similar shape, hardness and response to pain or stress as a natural tooth, and worked equally well for chewing. The researchers suggested that using similar techniques in humans could restore function to patients with organ failure.’

Every once in a while, something happens out of the ordinary in deep space. This event is even more out of the ordinary, maybe even hard to believe. This probably has a lot of people parsing through mountains of data to try and explain why an object 8.2 billion light years away appears out of nowhere, and then disappears out of nowhere. Scientists are not even sure what to label it! Read more:
