For some older adults, the online video game World of Warcraft (WoW) may provide more than an opportunity for escapist adventure. Researchers have found that playing WoW boosted cognitive functioning for older adults – particularly those who had scored poorly on cognitive ability tests before playing the game.
Oncologists have known that in order for cancer cells to spread, they must transform themselves so they can detach from a tumor and spread to a distant organ. Now, scientists have revealed critical steps in what happens next — how these cells reverse the process, morphing back into classical cancer that can now grow into a new tumor.
Can animals’ survival instincts shed additional light on what we know about human emotion? Neuroscientists pose this question in outlining a pioneering theory, drawn from two decades of research, that could lead to a more comprehensive understanding of emotions in both humans and animals.
New twist on nanowires: Technology can control composition and structure of these tiny wires as they grow
Nanowires — microscopic fibers that can be “grown” in the lab — are a hot research topic today, with a variety of potential applications including light-emitting diodes and sensors. Now, researchers has found a way of precisely controlling the width and composition of these tiny strands as they grow, making it possible to grow complex structures that are optimally designed for particular applications.
