The Scientist on The Pulse, March 21

Big Bang ripples, ancient moss revived, and lab-made heart tissue

In this installment of The Pulse on the public radio station WHYY, The Scientist’s associate editor Kerry Grens talks about physicists finally uncovering evidence of inflation, an event that attended the birth of our universe, 1,500-year-old moss that researchers brought back to life, and functional heart tissue that was made in the lab and implanted in mice.

Regarding finctional "heart" tissue, it's a matter of magnitude.  With mice, their hearts are so microscopic, any splotch of cells can be implanted and may potentially have an effect.  Other similar experiments have already been done, so, big yawn.  When the same thing is done in an adult infarcted pig heart, then I'll be impressed.
