...when. Under normal conditions, flies doze off, even during the day, after engaging in intense social activities, including courtship, acclimating to a new environment and fighting over mates and territory. But Shaw found that when flies were genetically bred to be missing the three genes - colorfully named rutabaga, period and blistered - that, among other functions, help regulate sleep, they failed to fall asleep after busy episodes of social activity...
...Such alertness may not seem like a bad thing, except that in a second paper in the same issue of Science, Giulio Tononi at the University of Wisconsin found that sleep appears to function as a critical shutoff valve for the fruit-fly brain. After a period of sleep, the volume of connections between nerve cells in the brain decreased, a condition that Tononi theorizes offsets the wakeful brain's activity. During waking hours, the brain keeps adding new information about its environment, forming new circuits and new connections in an ever thickening neural network. But even the fruit...
...While the medications currently prescribed are already much safer in the short term than the ones commonly used during the study period, their long-term effects on health are still unknown, since they simply haven't been circulating long enough for any damaging side effects to have surfaced. But, Ho notes, "I always felt the side effects of HIV are greater than the side effects of the drugs." After all, he says, "the side effect of unchecked HIV is death...
That's now changing. A new generation of Muslim builders and designers, as well as non-Muslims designing for Muslim groups, often in Europe or North America, are updating the mosque for the 21st century, sparking not just a hugely creative period in Islamic design, but one riven by controversy. The disputes over modern mosques echo larger debates taking place in the Islamic world today about gender, power and, particularly in immigrant communities, Islam's place in Western societies. Even the simplest design decision can reflect questions that are crucial to Islam and its adherents: Should women be allowed...
...Way” drags the whole mess down into plaintive misdirection as Morén sings “I don’t want to grow up / I don’t want to stay young” over a maddeningly meandering synth flute. “Blue Period Picasso” is narrated from, unsurprisingly, the point-of-view of a Blue period Picasso painting. It is as bad as it sounds. Case in point: “But I’m not just being blue… It’s just a part of what...
