...even in the middle of diverse cities. How is that possible? People don't realize that diversity isn't the same as integration. Blacks and whites in New York, where I live, are as segregated today as in 1910 [based on a sociologists' segregation index that measures how much contact people of differing races have with one another...
...particular how popular you are, may also affect how good a candidate for a flu vaccine you are. Vaccinating an entire population may be less efficient than choosing people at random, asking them to name their friends, and then vaccinating those friends. The friends are likely to come into contact with many people, so vaccinating them might do the most good, the authors argue. "You can achieve the same level of protection for the population at one-third the cost doing an intervention like this," Fowler said, according to CNN. He and Christakis hope to do a preliminary experiment monitoring...

...explanation for this new find, according to Bird, lies in the geometry of electrically charged water drops. While normal, uncharged water drops have round curves, charged ones have parabolic curves. So while normal drops repel or coalesce upon contact depending on the size of the drop and speed of collision, the unusual shape of charged drops causes them to come together briefly then separate...
...electric field is bringing the drops together until they contact, and then it’s just geometry from there on—nothing to do with electric fields,” said Bird...
