3-D weaving of genetically engineered stem cells is used to grow a living hip replacement

With a goal of treating worn, arthritic hips without extensive surgery to replace them, scientists have programmed stem cells to grow new cartilage on a 3-D template shaped like the ball of a hip joint. What’s more, using gene therapy, they have activated the new cartilage to release anti-inflammatory molecules to fend off a return …

1 to 10 billion earthlike planets in the Milky Way Galaxy

Researchers combine constraints on galaxy formation histories with planet formation models, yielding the Earth-like and giant planet formation histories of the Milky Way and the Universe as a whole. In the Hubble Volume (10^13 Mpc3 ), we expect there to be ∼ 10^20 Earth-like and ∼ 10^20 giant planets; our own galaxy is expected to …
