Moving while sticking
ntercalation—the slotting of cells in between one another—is an established method for converting short and fat into long and slim. This is all very well in slippery, adhesion-sparse mesenchymal tissues. But many such extension events occur in epithelial tissues, where cells are glued together by adhesion complexes. Claire Bertet, Lawrence Sulak, and Thomas Lecuit (IBDM, Marseille, France) now ...
متن کاملMoving While Black
Four experiments examined whether intergroup attitudes shape the speed with which Blacks are thought to be moving. When participants rated the speed of Black and White faces that appeared to be moving toward them, greater intergroup anxiety was associated with judging Black targets as moving more slowly relative to White targets (Experiments 1a and 1b). Experiment 2 demonstrated that this effec...
متن کاملMoving faults while unfaulting 3D seismic images
Unfaulting seismic images to correlate seismic reflectors across faults is helpful in seismic interpretation, and is useful for seismic horizon extraction. Methods for unfaulting typically assume that fault geometries need not change during unfaulting. However, for seismic images containing multiple faults and, especially, intersecting faults, this assumption often results in unnecessary distor...
متن کاملPerception of visual speed while moving.
During self-motion, the world normally appears stationary. In part, this may be due to reductions in visual motion signals during self-motion. In 8 experiments, the authors used magnitude estimation to characterize changes in visual speed perception as a result of biomechanical self-motion alone (treadmill walking), physical translation alone (passive transport), and both biomechanical self-mot...
متن کاملSticking Points
Nowadays a blood test usually requires a doctor’s visit, a needle poke in the arm, and a day-long wait for results to come back from a lab. So when Silicon Valley start-up Theranos promised a device that could perform more than a hundred of the most commonly ordered blood tests from just a fingerstick, doctors, patients, and investors were quick to get behind the company. Valued at $9 billion i...
