"Virgin Births" Won't Save The Smalltooth Sawfish From Extinction

The critically endangered smalltooth sawfish was recently found to be capable of asexual reproduction. It’s an exciting discovery for many reasons, but breathless claims by the media that sawfish could save their species from extinction by resorting to virgin births are wrong, wrong, wrong. Let’s explore why. » 6/18/15 6:40pm 6/18/15 6:40pm

Scientists Use AI To Solve A Long-standing Genetics Mystery

For years, biologists have sought to understand how the genes of planarians, a group of free-living flatworms, direct growth in specific body parts. An artificial intelligence tasked with the problem appears to have cracked the code, a breakthrough that demonstrates the incredible potential for “robot science.” » 6/08/15 9:20am 6/08/15 9:20am

A Handful Of Bronze-Age Men Could Have Fathered Two Thirds Of Europeans

Europe has surprisingly little genetic variety. Learning how and when the modern gene-pool came together has been a long journey. But thanks to new technological advances a picture is slowly coming together of repeated colonization by peoples from the east with more efficient lifestyles. » 5/22/15 3:00pm 5/22/15 3:00pm

What Made the Y Chromosome So Tiny?

The Y chromosome, a chunk of genetic code that is unique to male mammals, isn’t just physically smaller than the X. It also contains far fewer genes. The X has more than 1000 genes, while the Y has fewer than 200 —and most of them don’t even work. Why do men have this odd, stunted chromosome in their genomes? » 5/07/15 7:40pm 5/07/15 7:40pm

Scientists Make History By Genetically Modifying Human Embryos

After weeks of speculation, it can finally be confirmed that geneticists in China have modified the DNA of human embryos. It’s a watershed moment in biotech history, but the experiment may ultimately serve as a major setback in the effort to responsibly develop beneficial interventions involving the human germline.
