Medical Hypothermia: You Should Put Some Ice on That

Medical research over the past 70 years has shown how the careful chilling of patients can aid resuscitation, save lives and protect neurological function. Most recently, doctors have begun exploring how therapeutic hypothermia can improve patient outcomes in cases ranging from stroke to heart attacks, respiratory problems and injuries to the brain and spinal cord.

By staving off the destructive chain of events that begins when blood and oxygen stop flowing, this treatment also pushes back the customary timeline of brain death. As new, more radical procedures promise to push it back further still, we have to wonder …

The Centers for Disease Control and Prevention has to walk a fine line. Saving people from the nastiest infectious diseases and bioterror attacks requires that they study those same viruses and bacteria. But even in one of the most carefully controlled and well-equipped facilities on Earth, items are occasionally mishandled or misplaced.

What’s the worst that could happen? It’s not a rhetorical question when we take a tour of …

Biohackers Take DIY Approach to Biological Future

Not terribly long ago, do-it-yourself projects were the province of shade-tree mechanics and people who kept wood lathes in their garages. They dealt with grease and iron, wood and wiring, and left anything biological to the experts.

But today, body-modifying grinders implant jury-rigged biotech via the kitchen cutting board. Elsewhere, basement biohackers collaborate to build a better biological mousetrap, while volunteers teach basic genomics in community biotech spaces. Little by little, small pockets of enterprising people are working to make the long-promised post-human, cyborg, genomic future a reality.

10 History-making Hispanic Researchers

Far too many scientists who made major contributions to knowledge and human health go unremarked, forgotten save for the occasional postage stamp or Google doodle. So when I was offered the chance to write about a few of the many outstanding scientists who came from Spanish-speaking lands, cultures and ancestors, I was understandably excited…and a little nervous. On the one hand, combining such a varied assemblage of people under one term – especially the political term Hispanic – wasn’t ideal. On the other hand, it gave me the chance to explore, and raise awareness of, a remarkably diverse array of persons, backgrounds and accomplishments. I hope you’ll find their stories as inspiring as I did.

There was Madness to Their Method: The Western World Before the Scientific Method

One of the many things I enjoy about teaching my university class, Science, Feuds, Scandals and Hoaxes, is the opportunity to explore some of the most outrageous ideas ever to gain traction in the public mind. It’s easy to make fun today, but some of these ideas were grounded in reasoning that, though flawed, eventually gave rise to the right answer. Then again, there’s really no defending those doctors who thought that woman was giving birth to rabbit parts.
