Launched in March, Foursquare turns city maps into game boards. Members use text messages or applications for iPhones or Android phones to post when they are at a location like a bar or a restaurant. As incentive to share, your current location shows up on the Foursquare map to help you meet up with friends. Check in enough times from a coffee shop, for example, and you're dubbed its mayor. Give a shout-out from your gym 10 times in a month, and you might get a badge that dubs you a "Gym Rat." That gaming component...
...users is the site's plan to work with businesses to give freebies to loyal users. So far, some 200 businesses have signed on, including the Modmarket eatery in Boulder, Colo., which gives free pizza to users who check in 10 times and a free drink to the current mayor. "We get multiple people coming in and mentioning it," says owner Anthony Pigliacampo. "We're pretty psyched about...
...latest evidence for that assertion comes in a study just published in the journal Forest Ecology and Management, in which Finnish researchers looked at how the northern forests will respond as the growing season gets longer. In the current climate, says lead author Anna Kuparinen, of the University of Helsinki, pine and birch trees in the northernmost parts of Europe are stunted, in part because they have less time to grow each year than their more southerly counterparts. They've also evolved mechanisms that protect them from the harshest cold. "They actually stop growing before the frost comes," says Kuparinen...
...frost starts coming later, though, she says, they can't un-evolve overnight. "The current forests won't immediately start growing taller and stronger," she says. Eventually, the evolutionary process will catch up, as new seedlings without the frost response take over. "In principle, however," says Kuparinen, "this process will take a long time. The rate of evolution is slower than the rate at which climate will change." The forests would thus get no benefit, remaining stunted until seedlings without early dormancy genes can take root and take over...
...wife to arrange the killing of a man who was extorting and threatening him. The extortionist was fictitious, though, and Rosenberg was actually planning his own assassination. Unaware that the target was Rosenberg, the cousins contracted 11 hit men, more than half of whom are former or current military or police officers, to carry out the killing, investigators said.
