5:59 PM | Geo 730: October 22, Day 660: Punchbowl Strata
All three major components of the stratigraphy at Devils Punchbowl are visible here: the Astoria Formation forms the bedrock of the punchbowl itself. Contemporaneous Columbia River Basalt forms Otter Rock, offshore, as well as the headland on the far right horizon. Finally, flat-lying, probably Pleistocene, terrace sands have created the eroding bluff along the right and bottom edges. The role of plant cover in assisting the latter unit maintain some degree of coherence is evident in the grassy […]

5:36 PM | One Size Doesn’t Fit All When it Comes to Calling Codes
Resuscitation techniques have come a long way. Just a few years ago, there were only a handful of hospitals using therapeutic temperature management (TTM), also known as therapeutic hypothermia, to treat cardiac arrest patients.

5:24 PM | Sorry, Cat Haters, Science Isn't On Your Side
"Unfeeling" Cats Jetske via Flickr, CC BY 2.0 Some people just don't like cats. That's okay. Some people don't like pizza. Or dogs. Or Harry Potter. But some cat-haters aren't satisfied with not owning cats themselves. They need to drag the rest of us down with them. "Those who hate the cat hate him with a malignity which, I think, only snakes in the animal kingdom provoke to an equal degree." The first thing you notice when you dig around in the seedy underworld of […]

5:16 PM | How to Get Into Hobby RC: Learning to Fly Quadcopters
I’ve mentioned my recommended path for aspiring multi-rotor pilots several times in this column. Before buying a large, expensive ship with a camera attached, I think it is better to begin with a RC flight simulator and/or a small quad. I think that this approach will help you hone your piloting chops before accepting the risks of flying a bigger aircraft. I’m still holding firm to that opinion. I realize, however, that I have never adequately addressed how to use those tools to […]

  # 9234   The World Health Organization has released their 9th update to their Ebola Response Roadmap, indicating that the total number of cases is now just shy of 10,000 infections.  There are, of course, significant gaps in surveillance and reporting, and so these numbers are likely to be a substantial undercount.   Below I’ve posted some excerpts from the 12-page PDF report.  Follow the link to read the report in its entirety.   SUMMARY […]
