The lab-made embryos, crafted without any eggs or sperm and incubated in a device that resembles a fast-spinning Ferris wheel full of tiny glass vials, survived for 8.5 days. That's nearly half the length of a typical mouse pregnancy. In that time, a yolk sac developed around the embryos to supply nutrition, and the embryos themselves developed digestive tracts; neural tubes, or the beginnings of the central nervous system; beating hearts; and brains with well-defined subsections, including the forebrain and midbrain, the scientists reported in a study published Thursday (Aug. 25) in the journal Nature.

The single piece of paper was a jewel of the collection of the University of Michigan Library, according to a statement from the library. But an internal investigation by a professor of history has found that it's a fake: Watermarks in the paper date back to no earlier than the 18th century, over a hundred years after the death of the famed astronomer.

So, what happens if you don’t take out a splinter?

As Shaw watched, the large gator lifted its head higher and then slammed its unresponsive prey into the water.
