Cambridge, Massachusetts - One big problem faced by electrodes in rechargeable batteries, as they go through repeated cycles of charging and discharging, is that they must expand and shrink during each cycle - sometimes doubling in volume, and then shrinking back.

San Diego, California - Researchers at University of California, San Diego School of Medicine report that more than one in four female sex workers in two Mexican cities on the U.S. border entered the sex trade younger than age 18; one in eight before their 16th birthday. These women were more than three times more likely to become infected with HIV than those who started sex work as adults. They were also three times more likely to be violently coerced to engage in sex with male clients and seven times less likely to use a condom during their first month in the sex trade.
