Reptiles and things...this is the Titanoboa! They are calling this one of the greatest discoveries since the T-Rex! Discovered in a Colombian coal mine, its believed to have lived 59 million years ago, was 49 feet long, two feet wide, and weighed 2,500 lbs! Check out this awesome site from the Smithsonian Channel and learn more about the Titanoboa (there's even a cool Monster Snake Game there too!) Have FUN!: http://bit.ly/19sXMjB (p.s. I had my feet up while I was typing that...does anyone else get the HEEBIE-JEEBIES when it comes to snakes?)

A hypothesized mechanism for the origin of life, an event called abiogenesis.  In this version, called RNA world, small molecules called nucleotides formed in the waters of the early Earth during the Hadean Eon, and polymerized on the surface of clay minerals.  These simple chains of RNA could replicate themselves in solution, but only slowly and inaccurately.  An RNA molecule developed which would fold into a structure that catalyzed RNA polymerization; a ribozyme.  The first ribozymes would replicate their sister strands, and produce copies of themselves and other RNA molecules. 

     In the same environment, long chains of carbon molecules called phospholipids were formed.  These molecules have two parts, the tail, which is hydrophobic, and the head, which is hydrophillic.  Because of these properties phospholipids will stick together and form micelles and vesicles in water.  Vesicles can absorb RNA nucleotides, concentrating them and creating a space where they can replicate, mutate and evolve.  At some point a ribozyme became enclosed within a vesicle, starting a chain reaction that evolved into the multitude of biological forms that we see today.

   Because this event occurred more than 3.8 billion years ago, theories about how and where it happened are highly speculative.  Possible environments for abiogensis include hydrothermal vents on the ocean floor, hyper saline bubbles of water trapped in ice, radioactive lakes or lagoons on earths surface, and even in space or on another planet, brought to earth through a panspermia event.  We have very little molecular evidence of the first cells, but ribozymes and catalytic RNA molecules are embedded in the DNA replication machinery of all life.  Because evidence of this event has almost certainly been lost to time, the true mechanisms of the origin of life may remain a mystery to science.

You matter! =)

"Blowing in the Wind" - GROOVY SNEAK PEEK! 5, 4, 3, 2, 1...Count down to "Blowing in the Wind" - Groove on over to our website then click JOIN NOW! to do the "E" in STEM! Engineering Design Challenge: You are a groovy mechanical engineer who is inspired by the story of a young boy from Malawi, who, at fourteen years old, battled through extreme poverty to build a series of windmills from scratch that could generate electricity for his village – a luxury enjoyed by only 2 percent in Malawi. Using only the materials in your Groovy Lab in a Box, can you design and build a windmill which can fetch a pail of grooviness for those in need? Blowing in the Wind - Engineering Design Process During your Engineering Design Process, you will design and build several different kinds of groovy windmills. Explore and investigate forces and motion, potential and kinetic energy associated with windmills, various parts of a windmill, how different blade designs affect performance and how energy is transferred from wind into usable mechanical energy and much, much more. #STEMists do the "E" in #STEM! Engineering Design Challenge in every groovy box!
