Lego NXT Bot Beats Rubik's Cube Record 50

kkleiner writes "The current official human record for the Rubik's cube 3×3×3 puzzle is just 5.66 seconds. Now a robot called CubeStormer II did it in just 5.35 seconds. CubeStormer II is controlled by four Lego NXT 'bricks' that communicate via Bluetooth with a Samsung Galaxy SII smart phone. A special app on the phone takes a picture of the cube, solves the puzzle virtually, and then relays the solution to the Lego robot. From click to finish the whole process takes just seconds."

Scientists Derive Gelatin From Human Tissue 123

An anonymous reader writes "Conventional gelatin is made from collagen inside animals' skin and bones, however a group of researchers has managed to replace that animal base with a human one. The process involves taking human gelatin genes and inserting them into a strain of yeast, which can be cultivated to grow gelatin with controllable features. Jinchun Chen, the leader of the study, and his colleagues believe they can scale this process up to produce large amounts of human-based gelatin for medical uses. The research appears in the American Chemical Society's Journal of Agricultural and Food Chemistry."

8-Year-Olds Publish Scientific Bee Study Screenshot-sm 174

flintmecha writes "A group of British schoolchildren may be the youngest scientists ever to have their work published in a peer-reviewed journal. In a new paper in Biology Letters, children from Blackawton Primary School report that buff-tailed bumblebees can learn to recognize nourishing flowers based on colors and patterns. The paper itself is well worth reading. It's written entirely in the kids' voices, complete with sound effects (part of the Methods section is subtitled, ''the puzzle'duh duh duuuhhh') and figures drawn by hand in colored pencil."
