As long as there have been medical schools, medical students have been dissecting dead bodies to learn the finer points of human anatomy. But now there’s a high-tech twist to this gruesome rite of passage, with artificial cadavers going toe-to-toe with the real thing.
One artificial cadaver, made by
An early prototype of the SynDaver synthetic human patient.
SynDaver’s life-size “Synthetic Human,” costs upward of $40,000 and is made of synthetic “tissue” that shares certain physical and even chemical properties with real flesh — including water, fiber and salt content, according to the company’s website. The cadaver contains hundreds of replaceable muscles, bones, organs, and vessels. Some models can even simulate bleeding and breathing.
Cadavers on campus. Some schools have explored using synthetic cadavers in their curricula, since the real ones are in limited supply.
“Many smaller colleges and universities cannot afford a full cadaver lab, and this model, which closely approximates a real cadaver, is very cost effective and on the cutting-edge of the way we can teach anatomy to our students,” Kevin McDade, an instructor of biology at Penn State University, said in a written statement when the cadaver was purchased by the university in January.
Nothing like the real thing. But other professors have their doubts about the value of artificial cadavers.
“While synthetic cadavers or digital models can be useful for review, they are inadequate for learning anatomy,” Dr. Paulette Bernd, professor of pathology and cell biology at Columbia University Medical Center in New York City, told The Huffington Post in an email, adding that of 55 U.S. medical schools that participated in a 2013 survey, all continued to use real cadavers.
So maybe synthetic cadavers will catch on in a big way — or maybe they won’t. But no matter how you slice it, —> Read More

The summer season means long days and short nights, as observers in the northern hemisphere must stay up later each evening waiting for darkness to fall. It also means that the best season to spot that orbital outpost of humanity—the International Space Station—is almost upon us. Get set for multiple passes a night for observers based in mid- to high- northern latitudes, starting this week.(…)
