The medicine of the future could be artificial life forms      (via sciencedaily.com)     Original source 

Imagine a life form that doesn't resemble any of the organisms found on the tree of life. One that has its own unique control system, and that a doctor would want to send into your body. It sounds like a science fiction movie, but according to nanoscientists, it can—and should—happen in the future.

Survival of the newest: the mammals that survive mass extinctions aren't as 'boring' as scientists thought      (via sciencedaily.com)     Original source 

For decades, scientists have assumed that mammals and their relatives that survived challenging times (like those during mass extinctions) made it because they were generalists that were able to eat just about anything and adapt to whatever life threw at them. A new study into the mammal family tree through multiple mass extinctions revealed that the species that survived aren't as generic as scientists had thought: instead, having new and different traits can be the key to succeeding in the aftermath of a catastrophe.
