US Volcano Update: Kilauea, Cleveland and the Axial Seamount
Well, this week at the SERC Teaching Mineralogy, Petrology and Geochemistry Workshop has been busier than I thought (and yes, there was a Red Sox game mixed in), so not a lot of time to blog, but a few brief updates to share:
Hawai`i: Lots going on with the ongoing activity at Kilauea that is appearing to slow down - and a lot of USGS timelapse videos as well to check out. I glanced at the HVO Kilauea status and it seems that the activity at Pu`u O`o has prompted the draining of the lava lake at the summit crater, so we might be seeing some significant reorganization of the magmatic system at the volcano.
Alaska: We also got our first decent glimpse of the new dome on Cleveland volcano in the Aleutians. AVO doesn't seem to think that this activity is likely to lead to a big explosive event at Cleveland, but for aviation safety, a close eye will be kept on the volcano if the dome ends up plugging the conduit.
Off the coast of Oregon: I'll likely have more to say on this subject, but there has been a flurry of news about the eruption at Axial Seamount off the coast of Oregon. The eruption isn't going on right now, but rather it appears to have occurred in April, but only know did undersea research crews find the evidence (lava flows and new hydrothermal vents). I am a little disconcerted by all the media attention to the idea that the eruption was "predicted" - the study in question merely said that it would likely erupt "before 2014" ... so, you can drive a truck through that prediction. However, the discovery of the eruption is cool nevertheless.

What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
Beyond Beef sizzles and marbleizes just like real beef, Beyond Meat says.
- Shares of Beyond Meat opened at around $200 on Tuesday morning, falling to nearly $170 by the afternoon.
- Wall Street analysts remain wary of the stock, which has been on a massive hot streak since its IPO in May.
- Beyond Meat faces competition from Impossible Foods and, as of this week, Tyson.
Average waiting time for hitchhikers in Ireland: Less than 30 minutes. In southern Spain: More than 90 minutes.
- A popular means of transportation from the 1920s to the 1980s, hitchhiking has since fallen in disrepute.
- However, as this map shows, thumbing a ride still occupies a thriving niche – if at great geographic variance.
- In some countries and areas, you'll be off the street in no time. In other places, it's much harder to thumb your way from A to B.
A recent study used data from the Big Five personality to estimate psychopathy prevalence in the 48 contiguous states and Washington, D.C.
- The study estimated psychopathy prevalence by looking at the prevalence of certain traits in the Big Five model of personality.
- The District of Columbia had the highest prevalence of psychopathy, compared to other areas.
- The authors cautioned that their measurements were indirect, and that psychopathy in general is difficult to define precisely.
