“We Are All Primary Numbers Divisible Only By Ourselves.” – Jean Guitton

Throwing it way back! #TBT Pretty groovy, right? It's a map of Pangea - a supercontinent that formed roughly 300 million years ago - mapped with contemporary geopolitical borders. What you see here is an anachronistic mashup - a modern map, complete with geological features that did not exist 300-million years ago, with its various parts relocated to the general position they would have occupied before Pangea began rifting apart some 200-million years ago. It's a view of the supercontinent not often seen, and a mind-bending way of relating to the world on a geological time scale. #Pangea #ThrowbackThursday #supercontinent #ContinentalDrift

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.

Watch the whole video, I added a 2x Barlow for a closeup. Exciting to add Mercury to my list of planets I've seen in our Solar System! 😄🔭 .

International Observe the Moon Night (InOMN) is this Saturday, October 12th! Explore the interactive map below to see the location of InOMN 2013 events. http://observethemoonnight.org/ International Observe the Moon Night (InOMN) is an annual event that is dedicated to encouraging people to ‘look up’ and take notice of our nearest neighbor, the Moon. From looking at the Moon with a naked eye to using the most sensitive telescope, every year on the same day, people from around the world hold events and activities that celebrate our Moon. On this site, you can find information about an InOMN event near you or register your own event. We encourage everyone to join us in the celebration!

Scientists in Switzerland use sound waves to levitate, manipulate matter. http://bit.ly/15z86Ro As anyone with a subwoofer and a teenager knows, sound waves exert pressure. When those waves are bounced between carefully aligned surfaces, they can create what is known as a standing wave, in which the total pressure from the original wave and its reflection cancel each other out. Objects placed at spots along the wave with the lowest amplitude, known as node points, tend to stay put. Being able to manipulated matter without touching it promises a wealth of applications, from material sciences to biology. For instance nucleic acids can be introduced into cells – a process known as DNA transfection – without fear of contamination."You can basically play with cells in a droplet," says Foresti While commuting via acoustically levitated skateboards may be far off in the future, Foresti says that he hopes that other researchers will soon find novel uses for his method.
