Study Sequences Record Amount of Human microRNA

Discovered  in the nematode c. elegans, miRNA were once thought to be leftovers of an era when RNA ruled life processes on Earth (image by Bob Goldstein, UNC Chapel Hill).

An Arizona State University team has used a unique high-throughput screening system to complete the largest-ever analysis of microRNAs (miRNA), the puzzling little cousins of RNA that help regulate gene expression.

Their findings offer a new explanation for why groups of similar miRNA sequences, called miRNA families, are so plentiful in higher species of animals, including humans.

In honor of World Oceans Day (June 8), here’s my recent article on some of the remarkable discoveries made by marine biologists over the past few years. From clearing up the murky “lost years” of juvenile turtles to further solidifying our understanding of a jellyfish’s final fate, these delvers of the deep have shrunk what Shakespeare called “the vasty deep” to something a bit more fathomable but no less amazing. Find out more as I take a deep dive into …
