digitaltrends.com – Researchers at the Stevens Institute of Technology in New Jersey have come up with an unexpected way to produce electricity without fossil fuels: A mushroom covered with bacteria. The mushroom provides a safe environment for special cyanobacteria that generate electricity when light is shone on them.

By jump-starting tissue repair, the bioreactor was shown to help the amphibians regenerate a bigger, more complete appendage than they usually do in the wild.

sciencedaily.com – Analysis of ancient DNA of a mysterious extinct monkey named Xenothrix -- which displays bizarre body characteristics very different to any living monkey -- has revealed that it was in fact most closely related to South America's titi monkeys (Callicebinae). Having made their way overwater to Jamaica, probably on floating vegetation, their bones reveal they subsequently underwent remarkable evolutionary change.
