Modern Medicine Might Have Saved Lincoln

teflonscout Re:so, what this article is saying is... (281 comments)

But could we save Kennedy? Just kidding, on a more technical note, there are tons of cool new toys for medics and trauma doctors. I have been amazed by how slowly emergency rooms are adopting chitosan bandages like HemCon despite their proven effectiveness in Iraq. Pretty soon we may be able to use hydrogen sulfide to put people into suspended animation for very long surgeries.

LIDAR Maps to find Giant Trees

teflonscout teflonscout writes  |  more than 7 years ago

teflonscout (302958) writes "The Wired Science blog is running a story about the people, gear, and plane behind an effort to find redwood trees taller than the world record of 379 feet. Two technicians and a pilot from Sanborn Mapping Company slowly sweep across Redwood National Park in a raster pattern. They use LIDAR to gather 85,000 3D data points per second, creating a map with less than 0.5 meter resolution. This means that they can even identify individual tree species with the almost photolike data. Since the LIDAR laser beams can slip between tree branches, an image of the forest floor and treetops can be constructed. By subtracting the height of the forest floor from the trees, the heights of the trees can be calculated with tremendous accuracy. Once a grove of tall trees has been identified, Professor Steven C. Sillett of Humboldt State University will send his students into the forest to verify the heights of the giant trees."

teflonscout (302958) writes "When I think of bulletproof vests, the first word that comes to mind is Kevlar. Wired is running a story on Dynema SB61, a bulletproof material that is made of polyethylene. It is a higher grade of the plastic found in Tupperware. The story also mentions the recall of Second Chance bulletproof vests that were made from Zylon, a material that degraded slowly when exposed to moisture. At least one police officer was injured when a bullet penetrated his Zylon vest. Polyethylene is impervious to moisture. The first vests made from this new material are 5mm thick and can stop at 9mm bullet traveling at 1777 feet per second, which is slightly better than other top of the line vests."

teflonscout (302958) writes "Wired is running a story about the Journal of Visualized Experiments. JoVE is a video sharing community that intends to make it easier for scientists to learn state of the art lab techniques and reproduce the complicated experiments perfromed by their colleagues around the world. Each video shows a researcher performing an experiment while narrating each step of the way. In one video, a Harvard Student demonstrates the Derivation of Hematopoietic Stem Cells from Murine Embryonic Stem Cells. Another video shows the Nuclear Transfer in Mouse Oocytes. Wired points out that the side could become a phenomenal educational tool and change the public perception of scientists for better or for worse. Just like MIT's Open Courseware gives anyone anywhere access to high quality educational materials, JoVE will give students the opportunity to see cutting edge experiments as if they were standing in a lab and looking over a scientist's shoulder."
