Move your microvilli
Polarized epithelial cells create tightly packed arrays of microvilli in their apical membrane, but the fate of these microvilli is relatively unknown when epithelial cell polarity is lost during wound healing. In this issue, Klingner et al. (2014. J. Cell Biol. http://dx.doi.org/10.1083/jcb.201402037) show that, when epithelial cells become subconfluent, actomyosin contractions locally within ...
متن کاملMapping Your Every Move
In 2005, our authors discovered grid cells, which are types of neurons that are central to how the brain calculates location and navigation. Since that time, they have worked to learn how grid cells communicate with other types of neurons-place cells, border cells, and head direction cells-to affect spatial awareness, memory, and decision-making.

متن کاملPollard to actomyosin: "freeze! Don't even move your head".
In the field of muscle biophysics, nothing has attracted more attention (or generated more controversy) than the Big Question: Does myosin rotate on actin to generate force? For at least two decades, textbooks have shown attractive and compelling cartoons in which the myosin head forms a weak-binding cross-bridge to actin at a 90° angle, then becomes a strong-binding cross-bridge at a 450 angle...
متن کامل"I could see your lips move": HAL and Speechreading
One of the amazing capabilities of HAL was the ability to speechread (lipread) the crucial conversation between Dave and Frank, where they discussed the possible disconnection of HAL. In this short essay, we briefly discuss the motivation behind computer speechreading, look at the brief history of the field, and describe the current state of computer speechreading research. Finally, we provide ...
