Wednesday Whatzits: Auckland's volcanic hazards, how to smell like Iceland, Kasatochi's climate impact and new books
Bright sunny Wednesday here in Ohio made all the better upon hearing that the miners trapped in the Chilean mine have started to make their way – one by one – to the surface. It truly was an amazing feat of engineering to rescue these men.
Some news for today:
Volcanic hazards for Auckland: It seems like the airing of the NZ TV3 drama “Eruption” about a fictional eruption of the Auckland Volcanic Field under New Zealand’s largest city, there has been more news on the potential volcanic hazards that threaten it. A study run by GNS Science and the University of Auckland found 29 new ash layers under the city – all between 400 and 80,000 years old. There are currently 9 seismic instruments around Auckland to help detect the first signs of any new eruptive activity in the volcanic field.
Kasatochi, sea life and carbon dioxide I’ve only scratched the surface of the many articles I’ve seen about a recent study by Roberta Hamme and her colleagues that details the plankton bloom related to the 2008 Kasatochi eruption in Alaska. The long-and-short of the study in Geophysical Research Letters was that the ash from the Kasatochi eruption (iron rich) helped trigged a plankton bloom in the ocean’s of the Pacific. The researchers monitoring how this bloom of photosynthetic life – which takes in carbon dioxide – would change worldwide CO2 levels. This is because one proposed method to sequester CO2 out of the atmosphere is to artificially produce their planktonic blooms and let the plankton absorb the carbon dioxide. However, Hamme found that even with the amount of material released by the volcanic eruption – far more than human’s could seed right now – that the plankton made very little dent in global atmospheric CO2. Well, looks like its back to the “ice cube in the ocean every now and then” plan.
Eau d’ Eyjafjallajökull: Nothing says “romantic evening” than the right perfume and what could be, um, more right than a perfume based on a eruption that closed the skies of Europe. I mean, you could think of yourself as Helen of Troy, but instead you have the odor that grounded a thousand planes. OK, well, that doesn’t sound too flattering, does it? Anyway, a company in Iceland is now marketing a perfume – called EFJ Eyjafjallajökull - made from glacier water from Eyjafjallajökull and it even comes with a piece of the volcano as a memento. Remember folks, Christmas is around the corner!
New Books: Finally, I happened to be browsing around the books on Amazon (mostly the volcano and baseball books) and found two potential gems that come out in early 2011. The first is the third edition of “Volcanoes of the World” by Lee Siebert, Tom Simkin and Paul Kimberly. This is the first new edition of the book in over 15 years and will have over 500 pages of volcanic information for us to devour. The second is for all of you interested at looking at igneous rocks in the field – it is called “The Field Description of Igneous Rocks” (shocking) and it is by Dougal Jerram and Nick Petford (two well known igneous petrologists) – and based on the description, sounds like a great place to start if you want to be able to read and interpret igneous rocks in the field.

Upstreamism advocate Rishi Manchanda calls us to understand health not as a "personal responsibility" but a "common good."
- Upstreamism tasks health care professionals to combat unhealthy social and cultural influences that exist outside — or upstream — of medical facilities.
- Patients from low-income neighborhoods are most at risk of negative health impacts.
- Thankfully, health care professionals are not alone. Upstreamism is increasingly part of our cultural consciousness.
The Bajau people's nomadic lifestyle has given them remarkable adaptions, enabling them to stay underwater for unbelievable periods of time. Their lifestyle, however, is quickly disappearing.
- The Bajau people travel in small flotillas throughout the Phillipines, Malaysia, and Indonesia, hunting fish underwater for food.
- Over the years, practicing this lifestyle has given the Bajau unique adaptations to swimming underwater. Many find it straightforward to dive up to 13 minutes 200 feet below the surface of the ocean.
- Unfortunately, many disparate factors are erasing the traditional Bajau way of life.
Some evidence attributes a certain neurological phenomenon to a near death experience.
Time of death is considered when a person has gone into cardiac arrest. This is the cessation of the electrical impulse that drive the heartbeat. As a result, the heart locks up. The moment the heart stops is considered time of death. But does death overtake our mind immediately afterward or does it slowly creep in?
An innovation may lead to lifelike self-reproducing and evolving machines.
- Scientists at Cornell University devise a material with 3 key traits of life.
- The goal for the researchers is not to create life but lifelike machines.
- The researchers were able to program metabolism into the material's DNA.
