...years are marked by nothing but peace and happiness - what is their litmus test? There are two key predictors of a resilient relationship, experts say: mutual support and a willingness to sacrifice. In a recent study of newlyweds who became first-time parents, Gottman found that two-thirds suffered sharp drops in happiness during their child's infancy, under the strain of new parenthood. But for one-third of couples, the experience was cohesive and increased intimacy. Gottman says he could predict which couples would blossom under stress: those in whom, years before, he had observed better communication and more...
...already know that higher gas prices discourage driving and reduce greenhouse-gas emissions - total vehicle miles traveled in the U.S. declined 3.6% in 2008 compared with the previous year, thanks largely to the sky-high price of gas for much of 2008. (The recession didn't help, but sharp declines in driving began well before the bottom dropped out of the economy.) As gas prices have fallen in 2009, however, driving has begun to tick back...
...temperature reached a chilly 41°F (5°C); infections slowly decline as the mercury rises, before stopping altogether at 86°F (30°C). (Tropical countries, where fairly constant, high temperatures are prevalent, tend to have relatively even rates of infection all year long, without the sharp peaks and valleys seen in cooler countries.) It's also possible that the drier air in winter can dehydrate mucus in the nasal passages, lowering the body's natural defense against the virus. (See five burning questions about swine...

Several of the protesters interviewed said they had read lengthy handbooks distributed via e-mail on how to act in street protests. (Read: "Crackdown Helps Sustain Iran's Protest Movement...
...electricians paid big money by growers to wire the sophisticated network of lights and air conditioners used to cool plants and subject them to round-the-clock illumination. The energy-chugging networks require an expert's touch to bypass the electric meter and tap straight into the grid. A sharp increase in electricity used to be a telltale sign of a grow house. Some growers have caught on, however, and are learning to mask their energy profile...
