Iceland’s Eyjafjallajokull volcano has had all the attention lately, but a much bigger and meaner eruption might be around the corner from its cousin, Katla. This beast almost always erupts around the same time as Eyjafjallajokull, and geologists don’t expect this eruption to be any different. Katla is actually connected to Eyjafjallajokull underground via a common magma chamber, thus the connected eruptions. The main concern is that the ash plume will be even bigger than Eyjafjallajokull’s and will cause even more air travel problems. Another major concern is the fact that Katla is underneath a huge glacier. When 2,000 degree lava comes into contact with that much ice, you’re bound to have major flooding, and history has shown that indeed Katla’s eruptions have caused flooding problems for Icelanders. In fact, I’d say the only thing Katla has on Eyjafjallajokull is that its name is hella shorter and easier to pronounce/spell. (Via Daily Galaxy)
I’m sure you’ve already seen plenty of Iceland volcano photos since it’s been so prevalent in the news lately, but I must share this link: Live Science has a really nice gallery of volcanic lightning images that are simply breathtaking. All of them are of the recent Eyjafjallajokull eruption.
The US Military is not generally known for being environmentally-friendly… let’s face it, they blow up things, destroying not only buildings but also the land, not to mention releasing tons of toxic smoke and gases from the explosives. However, the Navy is trying to at least make a dent in their carbon footprint by adopting renewable fuels for their fighter jets, and eventually all other fuel-consuming vehicles/ships/aircraft as well. They’re about to test a new Camelina-based biofuel for the first time in an F/A 18 Hornet fighter. These are the same types of jets flown by the famous aerobatics demo team the Blue Angels. It’s pleasantly surprising to see the military taking such important steps in the right direction. (Via EcoGeek/National Geographic)
In other news- I now have more homebrew for your drinking pleasure, if interested. It’s a hefeweizen from an ingredient kit. I plan for this this be my last kit brew. I feel confident enough now to start using/tweaking online recipes, buying the ingredients separately and creating some brews that can be truly called “my own creations.” I’m actually about to start on a Belgian blonde ale. This hefeweizen, though, is just a simple straight-up wheat beer. It’s not a Belgian style (no orange peels or corriander) so it won’t taste like Blue Moon, and it doesn’t use any funky yeast strains or spicing to produce fruity flavors (such as Yazoo’s hefe, which has a distinct banana nose to it). It’s actually a very middle-of-the-road, normal-tasting wheat beer. If you want any, you know how to get in touch with me.

The theory that the dinosaurs were wiped out from an asteroid impact near the modern-day Yucatan Peninsula is beginning to face major challenges. There’s no doubt that a huge impact caused the Chicxculub Crater, but some recent findings suggest that the impact may have occurred some 300,000 years earlier than originally thought. This comes as a second blow to the impact theory, with the first being the discovery/dating of the Deccan Traps in India. This gigantic volcanic feature is the result of a huge eruption that is believed to have lasted around 30,000 years. Can you imagine a massive volcano erupting for 30,000 years and covering an area equivalent to 1/2 of modern India with lava? Trust me, something on that scale is hard for the human mind to comprehend, but that much volcanic ash and gas in the atmosphere would’ve had a devastating effect on the ecosystem, and almost certainly played a major role in the extinction of the dinosaurs. Get ready for science textbooks to be re-written, because the asteroid impact theory is about to see the same fate as the dinosaurs themselves. (Via Daily Galaxy)
NASA recently teamed up with the Air Force Office of Scientific Research to test a new, Earth-friendly type of solid rocket fuel. I’m not exactly sure of the details, but somehow they’ve managed to make rocket fuel out of aluminum powder and ice. Yes ice… as in frozen water. The secret apparently is that the aluminum powder is so finely ground that it’s considered “nanoscale.” The nanoscale aluminum has so much surface area in contact with the water ice that the exothermic reaction when it burns is more efficient than normal solid rocket fuel, which is usually powdered aluminum (not nanoscale) mixed with an oxidizer such as ammonium perchlorate and a binding agent. Seriously though, who would’ve ever thought you could make rocket fuel out of ice and aluminum? It just sounds crazy, but it’s true. (Via EurekAlert)
When you think of the type of person who becomes an astronaut, you don’t typically think of race car drivers or musicians, but two of the astronauts about to launch on Space Shuttle Discovery tomorrow morning are just that- a former off-road truck racer and a drummer. Check out this Space.com article to find out more about Commander Rick Struckrow, formerly a Baja off-road race driver, Pilot Kevin Ford who is also a drummer, and several other astronauts who come from surprising backgrounds.
