It depends on who you ask. Earlier this week, researchers announced that they'd successfully turned adult skin cells into embryonic stem cells. Headlines were made — including more than one that heralded this as the first step in human cloning. If you believe The New York Times, The Los Angeles Times, and Fox News, this research was a big deal. The Boston Globe and The Washington Post, however, had a different take. According to those sources, this is more of a technical advance (but not one that counts as a "breakthrough") and something that's unlikely to have any clinical relevance whatsoever.
Named after the Lernaean Hydra, a many-headed water monster of Greek and Roman mythology, the real hydra is a small fresh-water creature with incredible biological superpowers that enable it to regenerate and live "forever." Unlike the Lernaean Hydra, it doesn't not guard an entrance into the underworld. We think. From KQED's Deep Look: Cut a… READ THE REST
Scientists recently reported a major milestone in the creation of human-animal hybrids. Researchers from the Salk Institute for Biological Studies and colleagues, seen above, injected human stem cells into monkey embryos in vitro. Several of the chimera embryos survived for 19 days. Eventually, these hybrid animals could be used for testing new drugs or to… READ THE REST
Via US Geological Survey: This video clip shows HVO geologist Tim Orr sampling lava from an active pāhoehoe breakout on the episode 61g lava flow. The chemistry of these lava samples provides information on the magma plumbing system. Sampling has been a regular part of monitoring Kīlauea Volcano's ongoing Pu'u 'Ō'ō eruption. READ THE REST
If you've ever seen a 3D printer in action, you know it's a pretty wondrous process. Even if you're crafting nothing more than a plastic bauble or a geometric shape, just watching that filament settle and build into something recognizable and useful is fairly awe-inspiring. And man, to a kid…it's like a miracle. And they really,… READ THE REST
High school Spanish class is permanently embroidered into most of our brains. Vocabulary quizzes. Verb conjugation drills. Language lab. It's all tattooed on our souls like it happened yesterday, right? Estudiantes. Escuchen. Language learning doesn't have to be like that. Instead of being trapped in endless repetitions and dry academic book learning, Jumpspeak wants to… READ THE REST
