Wonder Women Challenging science culture

We’re hearing about harassment of, and barriers to, women seeking careers in politics and entertainment. But what about science? Science is supposed to be uniquely merit-based and objective. And yet the data say otherwise. A new study reveals widespread harassment of women of color in space science. 

We look at the role that a hostile work environment plays in keeping women from pursuing scientific careers. While more women than ever are holding jobs in science, the percentage in tech and computer science has flattened out or even dropped.  A memo from a software engineer at an Internet giant claims it’s because female brains aren’t suited for tech. Find out what the science says.

Plus, women staring down discrimination. One woman’s reaction to her guidance counselor’s suggestion that she skip calculus and have babies. And SACNAS, the organization changing the face of science for Latina and Native American women.

The biotech tool CRISPR lets us do more than shuffle genes.  Researchers have embedded an animated GIF into a living organism’s DNA, proving that the molecule is a great repository for information.  This has encouraged speculation that DNA could be used by aliens to send messages.

ENCORE  We all get defensive sometimes.  For some animals, evolution has provided a highly effective mechanism for saying “back off!”.  A puncture by a pair of venom-filled fangs gets the point across nicely.

ENCORE  Birds do it, bees do it, but humans may not do it for much longer.  At least not for having children.  Relying on sex to reproduce could be supplanted by making babies in the lab, where parents-to-be can select genomes that will ensure ideal physical and behavioral traits.
