Top 10 Bad Things That Are Good For You




    Sex

    Scientists have found that the benefits of sex go beyond immediate, ahem, gratification and satisfying the goal of procreation. Besides the obvious evolutionary purposes, we can all take pleasure in the news that having sex is an easy way to reduce stress, lower cholesterol and improve circulation throughout the body. As if you needed another excuse.



    Chocolate

    Chocolate lovers rejoice: study after study lately has touted the magical benefits of the indulgent treat, which is packed with the antioxidant flavonols that prevent certain cancers and keep your arteries from clogging. The most recent news? These powerful chemicals may even increase blood flow to the brain, warding off dementia. Just stick to the highest cocoa content possible-the bars packed with sugar don't help your health one bit.



    Red Wine

    A crucial ingredient in the diets of the world's heart-healthiest populations-like those Bordeaux-guzzling French-red wine has long been known to have potent anti-cancer and artery-protecting benefits. The key, some studies indicate, is an antioxidant found specifically in the skin of red wine grapes, called resveratrol. The latest studies even link resveratrol to greater endurance, a reduction in gum disease and Alzheimer's. White wine, which is fermented after the skins are removed, is less beneficial according to some studies.



    Marijuana

    It's medicinal, we swear! Marijuana, often associated with memory loss, is ironically now being hyped as a way to stave off the ultimate form of memory loss: Alzheimer's. Recent studies on mice suggest that anti-inflammatories found in the drug prevent the clumping of brain proteins, one major cause of the disease. So when should you start preventative therapy? We suggest waiting for the human studies to wrap up.



    Maggots

    They're creepy, slimy and altogether ooky, but maggots can save your life. These squirmy larvae are science's newest wonder-cure and were approved in 2003 as the Food & Drug Administration's only live medical device. Placed on serious wounds, maggots mimic their "wild" lifestyle and munch on bacteria and dead tissue, stimulating healing and helping to prevent infection.




    Sunlight

    Exposure to the sun's rays is necessary to survive, but can also kill you in gross, cancerous quantities. Asthmatics, at least, could benefit from measured doses of ultraviolet rays, according to scientists. Sunlight suppressed the immune reactions that cause asthma in some lab studies with mice and could be used to treat humans afflicted with the disease in the future. And sunlight-even if indirect, such as on a shaded porch-is known to boost the mood. Extra sunlight can help office workers avoid afternoon drowsiness, a recent study found. There's still no excuse to head outside and bake, however.

    Valued Opinions


    LSD

    We're definitely not in the business of advocating drug use. But check out this interesting science: In heavy drinkers, small doses of LSD have been thought to help bypass the rock-bottom stage of alcoholism and prevent relapses. These studies-some decades old-were done in closely monitored, clinical settings; many patients haven't had a drink in the many years since. It's an interesting finding that needs a lot more investigation, and not a remedy that should ever be tried at home. Meantime, and this may come as no surprise, recent study of 36 volunteers who took an LSD-like drug in a lab setting had them reporting mystical experiences and behavior changes that lasted for weeks.

    Coffee

    Java is one of the most debated substances around. Is it good for you? Is it bad for you? Both? The consensus, now anyways, seems to favor those who enjoy their morning jolt-unrelated studies claim coffee is a major source of antioxidants in our diet and can help lower your risk of diabetes. Something in the beans is also thought to ease the onset of cirrhosis of the liver and pancreatitis, good news for those who like to party hard all night before their morning caffeine boost.


    Anger

    if you're one of those people who tends to bottle things up, only to explode ... don't hold it in so long. Studies show that bursts of anger here and there are good for the health, and can be an even more effective coping mechanism than becoming afraid, irritated or disgusted. Anger, like the consumables in this list, however, is best in moderation: stay angry for long periods of time and you'll be plagued with a host of health issues, like blood pressure, sleep disorders and lung damage.


    Beer

    The newest bad kid on the block, beer has long been overshadowed by its healthier alcoholic cousins. While no one's suggesting you switch that glass of antioxidant-rich Pinot Noir for a tall glass of lager-there's still that beer gut to worry about-new research has suggested that moderate beer intake can actually improve cardiovascular function. Now if only a scientist will discover the health benefits of ballpark franks and chicken wings. Heaven.

Things You Should Know about Animals



    Parrot Talk More than Just Squawking

    Parrot speech is commonly regarded as the brainless squawking of a feathered voice recorder. But studies over the past 30 years continually show that parrots engage in much more than mere mimicry. Our avian friends can solve certain linguistic processing tasks as deftly as 4-6 year-old children. Parrots appear to grasp concepts like "same" and "different", "bigger" and "smaller", "none" and numbers. Perhaps most interestingly, they can combine labels and phrases in novel ways. A January 2007 study in Language Sciences suggests using patterns of parrot speech learning to develop artificial speech skills in robots.

    Elephants Do Forget, but They're Not Dumb

    Elephants have the largest brain -nearly 11 pounds on average- of any mammal that ever walked the earth. Do they use that gray matter to the fullest? Intelligence is hard to quantify in humans or animals, but the encephalization quotient (EQ), a ratio of an animal's observed brain size to the expected brain size given the animal's mass, correlates well with an ability to navigate novel challenges and obstacles. The average elephant EQ is 1.88. (Humans range from 7.33 to 7.69, chimpanzees average 2.45, pigs 0.27.) Intelligence and memory are thought to go hand in hand, suggesting that elephant memories, while not infallible, are quite good.

    Giraffes Compensate for Height with Unique Blood Flow





    The stately giraffe, whose head sits some 16 feet up atop an unlikely pedestal, adapted his long neck to compete for foliage with other grazers. While the advantage of reach is obvious, some difficulties arise at such a height. The heart must pump twice as hard as a cow's to get blood up to the brain, and a complex blood vessel system is needed to ensure that blood doesn't rush to the head when bent over. Six feet below the heart, the skin of the legs must then be extremely tight to prevent blood from pooling at the hooves.
    Many Fish Swap Sex Organs


    With so many land creatures to wonder at, it's easy to forget that some of the weirdest activities take place deep in the ocean. The strange practice of hermaphroditism is more common among species of fish than within any other group of vertebrates. Some fish change sex in response to hormonal cycle or environmental changes. Others simultaneously possess both male and female sex organs.

    Baby Chicks and Brotherhood


    It's a mistake to think of evolution as producing selfish animals concerned only with their own survival. Altruism abounds in cases where a helping hand will encourage the survival of genetic material similar to one's own. Baby chicks practice this "kin selection" by making a special chirp while feeding. This call announces the food find to nearby chicks, who are probably close relations and so share many of the chick's genes. The key to natural selection isn't survival of the fittest animal. It's survival of the fittest genetic material, and so brotherly behavior that favors close relations will thrive.

    Mole-Rats aren't Blind


    With their puny eyes and underground lifestyle, African mole-rats have long been considered the Mr. Magoos of rodents, detecting little light and, it has been suggested, using their eyes more for sensing changes in air currents than for actual vision. But findings of the past few years have shown that African mole-rats have a keen, if limited, sense of sight. And they don't like what they see, according to a report in the November 2006 Animal Behaviour. Light may suggest that a predator has broken into a tunnel, which could explain why subterranean diggers developed sight in the first place.

    For Beavers, Days Get Longer in Winter

    Beavers become near shut-ins during winter, living off of previously stored food or the deposits of fat in their distinctive tails. They conserve energy by avoiding the cold outdoors, opting instead to remain in dark lodgings inside their pile of wood and mud. As a result these rodents, which normally emerge at sunset and turn in at sunrise, have no light cues to entrain their sleep cycle. The beaver's biological sense of time shifts, and she develops a "free running circadian rhythm" of 29-hour days.

    Birds Use Landmarks to Navigate Long Journeys


    Can you imagine a road trip vacation without missed exits, stubborn drivers or map-folding disasters? Of course you're not a bird. Pigeons can fly thousands of miles to find the same roosting spot with no navigational difficulties. Some species of birds, like the Arctic tern, make a 25,000 mile round-trip journey every year. Many species use built-in ferromagnets to detect their orientation with respect to the Earth's magnetic field. A November 2006 study published in Animal Behaviour suggests that pigeons also use familiar landmarks on the ground below to help find their way home.

    Whale Milk Not On Low-Fat Diets


    Nursing a newborn is no "small" feat for the whale, whose calf emerges, after 10 to 12 months in the womb, about a third the mother's length (that's a 30-foot baby for the Blue whale). The mother squirts milk into the newborn's mouth using muscles around the mammary gland while the baby holds tight to a nipple (yes, whales have them). At nearly 50 percent fat, whale milk has around 10 times the fat content of human milk, which helps calves achieve some serious growth spurts -as much as 200 pounds per day.

    Crocodiles Swallow Stones for Swimming

    The stomach of a crocodile is a rocky place to be, for more than one reason. To begin with, a croc's digestive system encounters everything from turtles, fish and birds to giraffes, buffaloes, lions and even (when defending territory) other crocodiles. In addition to that bellyful-o'-ecosystem, rocks show up too. The reptiles swallow large stones that stay permanently in their bellies. It's been suggested these are used for ballast in diving.
