Massive extraterrestrial rock hit earth 13 millennia ago, according to nano-evidence
Posted by: | CommentsAbout 13,000 years ago, a chunk of a comet or asteroid hurtled into the atmosphere at a shallow angle, superheating the atmosphere around it as it careened toward the surface. The air grew hot enough to ignite plant material and melt rock below the object’s flight path. Within a few microseconds, atmospheric oxygen was consumed and the freed carbon atoms condensed into nanodiamond crystals.
10 year old accidentally creates new molecule in science class
Posted by: | CommentsClara Lazen is the discoverer of tetranitratoxycarbon, a molecule constructed of, obviously, oxygen, nitrogen, and carbon. It’s got some interesting possible properties, ranging from use as an explosive to energy storage. Lazen is listed as the co-author of a recent paper on the molecule. But that’s not what’s so interesting and inspiring about this story. What’s so unusual here is that Clara Lazen is a ten-year-old fifth-grader in Kansas City, MO.
Tetranitratoxycarbon Professor Robert Zoellner holds a model of tetranitratoxycarbon. He has a co-authorship on a paper about the new molecule–along with ten-year-old Clara Lazen.
Visualization challenge winners teach science through art
Posted by: | CommentsA multicolored mouse eye, the macro-scale universe, alien slugs on the face of a baby cucumber — all these images accomplish a pretty impressive feat: They look awesome, and they can teach us something about the world we live in and our place in it. They are among the winners of the 2011 International Science and Engineering Visualization Challenge, sponsored by the journal Science and the National Science Foundation.
Illustration First Place – The Cosmic Void
At first glance, it looks like this could be a microscopic image of tree bark or seashell; or it might be a cluster of blood cells in the body. But this evocative image depicts the grandest scales of all — streams of matter delineating the network of cosmic voids, each tens of millions of light years across.
Matter accumulates where the voids meet, forming a cosmic web
of walls, filaments, and clusters of galaxies. This illustration was awarded first place in the informational graphics category in the 2011 Science/NSF International Science & Engineering
Visualization Challenge.
9/11: new theory on collapse World Trade Center
Posted by: | Comments
More than ten years after the fact, a scientists based at the Norwegian research institute SINTEF is proposing that a well-documented chemical reaction spelled the ultimate demise of the Twin Towers after the attacks of September 11, 2001. This isn’t another conspiracy theory, nor is it proven fact. But Christian Simensen theorizes that a mix of molten aluminum from the aircraft bodies mixed with water from the sprinkler systems could have catalyzed secondary blasts that brought the World Trade Center towers to the ground.
