Bacteria brews biofuel with potential to replace high-energy rocket fuel - Researchers at the Georgia Institute of Technology and the US Department of Energy’s Joint BioEnergy Institute have engineered a bacterium that could yield a new source of high-energy hydrocarbon fuel for rocketry and other aerospace uses. High-energy, specific-use hydrocarbon fuels such as JP-10 can be extracted from oil, along with more commonly used petroleum fuels, but supplies are limited and prices are high – approaching US$7 per liter. That’s where the new bacterium, engineered by Georgia Tech scientists Stephen Sarria and Pamela Peralta-Yahya, could come in. By introducing enzymes into the strain of E. coli bacterium a reaction is developed that yields pinene, a cyclic hydrocarbon related to isoprene – a major ingredient of pine resin and a vital precursor to a biofuel that offers an energy density comparable to JP-10. The biofuel is then produced by “dimerising,” or linking together, two molecules of pinene via chemical catalysis. (via Bacteria brews biofuel with potential to replace high-energy rocket fuel)

Burrrrrrr its cold outside!  This Saturday and Sunday at the Maker Space, beat the chill with the coziest workshop in town, where we learn how to hand sew and make our very own stuffed animals or small pillows.  We will learn how to use needle and thread to sew on buttons and make stitches too create a funny faced Stuffie or a cool little pillow. 

We have two workshops each day, the first from 1:30-3:00 and the second from 3:30-5:00.  Register on the day of the event at the NYSCI admissions area.

Hope to see you there.  Stay warm!

Check back for more Maker Space events happening in March: http://nysci.org/events/2014-03/

That’s what I call a weather map!

Remember that animated wind map of the United States from a while back? Well, now there’s one of the whole earth! You’ve got to check out the interactive site (which is updated with near current weather) because these images don’t do it justice. YOU CAN ORBIT THE EARTH! YOU CAN ZOOM! YOU CAN SEE WIND SUPERIMPOSED ON TEMPERATURE, PRESSURE AND CLOUDS. Standing ovation to developer Cameron Beccario! (and thanks to my friend Alice Anderson for giving me the heads up)

Part of the Allende meteorite, from which nanodiamonds aka StarStuff were derived by Curator of Meteoritics Philipp Heck. This is the largest meteorite of its kind to ever land on earth. The specks and dots are calcium-aluminum-rich inclusions, and are the oldest known matter formed in our Solar System.
EDIT: Just to reiterate, we know how old the Solar System is because of this meteorite.
