Large Scientific Collaborations Aim to Complete Human Genome
Thirty years out from the start of the Human Genome Project, researchers have finally finished sequencing the full 3 billion bases of a person’s genetic code. But even a complete reference genome has its shortcomings.

Study: Telomeres Don’t Shorten with Age in Longest-Lived Bats
Diana Kwon | Feb 7, 2018
Researchers find that while bats in the Myotis genus don’t produce telomerase, the enzyme that lengthens telomeres, they possess 21 telomere maintenance–related genes.
