POPSBisexual Species: Unorthodox Sex in the Animal Kingdom Nevertheless, the study of homosexual activity in diverse species may elucidate the evolutionary origins of such behavior. Researchers are now revealing, for example, that animals may engage in same-sex couplings to diffuse social tensions, to better protect their young or to maintain fecundity when opposite-sex partners are unavailable—or simply because it is fun. These observations suggest to some that bisexuality is a natural state among animals, perhaps Homo sapiens included, despite the sexual-orientation boundaries most people take for granted. “ the categories of gay and straight are socially constructed,” Anderson says.

POPS20 Things You Didn't Know About Sex
6 Barbary macaques have a distinctive way to get their mates to make a sperm donation: yelling. If the female does not shout, the male almost never climaxes. 7 How do we know this? German primatologist Dana Pfefferle watched a group of macaques, counting the females’ yells and the males’ pelvic thrusts. She says this work is “quite weird, but it’s science.” 8 Here in the US of A, that kind of stuff ends up on YouTube. 9 Because Barry White sounds terrible underwater: Fish can produce a variety of noises with their bones, teeth, and gas bladders. Grant Gilmore of Estuarine Coastal and Ocean Science Inc. says that male fish probably use some of these sounds to woo females. 10 The spiny anteater, an egg-laying mammal native to Australia and New Guinea, has a penis with four heads, but only two fit into the female at once. 11 The tiny male paper nautilus, an octopus, impregnates the much larger female by shooting his penis (a modified tentacle) into her—and leaving it there.

POPSHow to Hitchhike Across the Globe Without Leaving Your Living Room The 360° World Atlas DVD lets anyone with a computer become a virtual hitchhiker, no packing or neck-craning required. Creator Everen Brown does all the hard work for you. He jets around the globe, lugging a 40-pound bag full of 600 rolls of film past airport security, and picks a picture-worthy spot. Then he takes one of the world’s last Globuscope rotational cameras (no longer in production), holds it over his head (sometimes he lies on his stomach), and waits (sometimes for hours) for the right shot. When he sees it, snapping the picture takes only a second. The lens rotates full circle, so you get to see what’s across from the Taj Mahal’s minarets too. Once Brown develops the film, he embeds the images into an interactive atlas ($69.95, www.360atlas.com) that shows off head-turning views, panorama style.

POPSKing Penguins face extinction as planet warms An example of how a broken link in a food chain can wipe the whole chain out. Their main diet , small fish, and squid, in turn rely on krill-tiny shrimp- which are sensitive to temperature change. Many Whale species prime source of food is also krill. There are many other creatures whose sensitivity to temperature can make life for them literally impossible either through being unable to survive themselves or through a threat to their food sources and so food chains. The environment is a house of cards, being dismantled from the bottom up. When the house collapses, it will do so in a flash. We won't have time to get our coats.
