‘We live in a universe that’s just right for us’: study suggests testing the anthropic principle
https://commons.wikimedia.org/wiki/File:Multiverse.png. Credit: Silver Spoon The “anthropic principle” that the universe we live in is finely tuned to harbor life was first proposed by Brandon Carter in 1973. Since then, this principle has caused great debate. A paper written by Nemanja Kalopá, a physicist in the Department of Physics and Astronomy at the University of California, Davis, and Alexander Westphal, a…

Testing of thousands of RNA enzymes discovers first ‘Twister ribozyme’ in mammals
A novel cleavage high-throughput assay (CHiTA) developed at Penn State University provides a flawless method to characterize thousands of diverse small self-cleaving RNA enzymes called Twister ribozymes in a single experiment. This image shows 2D models of some of the ribozymes tested that had defects in the helical and loop elements but still remained active, demonstrating that the Twister ribozyme’s…
