  • A zombie howto

    Fri, 2005-10-28 22:50 -- John Hawks

    In honor of the season, HowStuffWorks.com has an article on the workings of zombies.

    Nota bene:

    Mummies can bear a striking resemblance to zombies, even down to the guttural speech and shambling walk. Their deliberate physical preservation, however, sets them apart from ordinary zombies.

    Here is some good advice if zombies are chasing you:

    Also, avoid common mistakes like:

    • Sheltering in a vehicle to which you do not have the keys
    • Leaving blades, cudgels or other basic weapons out for zombies to find
    • Teaching zombies how to use firearms
    • Giving your only weapon to anyone who is hysterical
    • Retreating to a basement or cellar without taking supplies with you
    • Getting into an elevator in a building infested with zombies
    • Letting personal feelings and arguments get in the way of survival

    My favorite part? When I viewed the article, there was a list of "popular searches" on the sidebar. The "popular searches": Bounty Hunting, Dreams, Halloween, Tarot Card, Witchcraft, and Creationism!

    Cited in a lecture I heard today, from T. H. Huxley:

    How it is that anything so remarkable as a state of consciousness comes about as a result of irritating nervous tissue, is just as unaccountable as the appearance of Dun when Aladdin rubbed his lamp.

  • "Ghosts of reviewers past"

    Mon, 2005-10-24 09:32 -- John Hawks

    Googling something else entirely brought me this page by Edmund D. Brodie III, chronicling a few of the comments from manuscript reviews he's received over the years.

    Personally I'd need a lot more self-confidence than I have to put that kind of stuff out there. Or maybe I'm just not far enough away yet to laugh about it. (Who am I kidding? Alpha Centauri wouldn't be far enough away.)

    It illustrates very well why I always try to be as careful in my reviews as I am in my papers.

  • Natural selection in action

    Fri, 2005-10-21 11:39 -- John Hawks

    In honor of Halloween, the Washington Post has a story on extreme pumpkin-growers. It's a great example of massive phenotypic change in a few generations:

    Thousands of new growers, even including some in the warm, pumpkin-unfriendly climes around Washington, have been attracted to the mad-scientist thrill of growing a fruit the size of a boulder. For some reason, at least 80 percent of them have been men.

    Over the years, more growers have meant more pumpkins, and more chances to cross one behemoth with another.

    As this practice has become more popular, the seeds of certain well-known pumpkins -- such as a 723-pound New York specimen whose illustrious offspring have made it the Alydar of squash -- can bring hundreds of dollars at auction. At training seminars, growers will play "pumpkin poker," for one seed a hand.

    Everyone's dreaming that these unions of big pumpkins will produce a generation that is bigger still.

    "We've put a man on the moon. We've run the four-minute mile," said Ray Waterman, who runs a seed and supply company outside Buffalo. "And now we're going to grow a 2,000-pound pumpkin."

    The world record size has gone from 400 pounds in the 1980's up to 1469 points this month. But it's not all genetics:

    While the pumpkin's roots were sunk in the soil, Beauchemin shaded its prized fruit from the elements and placed it on a low-friction fabric. In the weeks to come, he knew, the mega-pumpkin would expand so fast that the roughness of the bare ground might slow it down.

    "It never felt the dirt," he said. "And it never felt the rain."

    With all their fertilizing and watering, these people are making a pumpkin secular trend. For fame, glory, and -- for the not-so-lucky -- the chance to cut the giant squash in half and fit a trolling motor for a spin around the river.

    From Jerry Pournelle:

  • Alien vs. Predator

    Wed, 2005-10-05 17:30 -- John Hawks

    The AP article ends this way:

    Wasilewski said a 10- or 20-foot python also could pose a risk to an unwary human, especially a child. He added, however, "I don't think this is an imminent threat. This is not a 'Be afraid, be very afraid' situation."

    Oh, I beg to differ. It begins this way:

    MIAMI - The alligator has some foreign competition at the top of the Everglades food chain, and the results of the struggle are horror-movie messy.

    A 13-foot Burmese python recently burst after it apparently tried to swallow a live, six-foot alligator whole, authorities said.

    Yes, there are photos.

    The gory evidence of the latest gator-python encounter -- the fourth documented in the past three years -- was discovered and photographed last week by a helicopter pilot and wildlife researcher.

    The snake was found with the gator's hindquarters protruding from its midsection. Mazzotti said the alligator may have clawed at the python's stomach as the snake tried to digest it.

    In previous incidents, the alligator won or the battle was an apparent draw.

    It's like Thunderdome out there!

  • Killer Navy cetacean squad unleashed by Katrina?

    Mon, 2005-09-26 17:57 -- John Hawks

    On the topic of animal intelligence, there is this from The Observer:

    It may be the oddest tale to emerge from the aftermath of Hurricane Katrina. Armed dolphins, trained by the US military to shoot terrorists and pinpoint spies underwater, may be missing in the Gulf of Mexico.

    Experts who have studied the US navy's cetacean training exercises claim the 36 mammals could be carrying 'toxic dart' guns. Divers and surfers risk attack, they claim, from a species considered to be among the planet's smartest. The US navy admits it has been training dolphins for military purposes, but has refused to confirm that any are missing.

    Apparently Navy personel are demanding to inspect other missing captive dolphins that have been found after the storms, leading some to believe they must have lost their own, which were headquartered near Lake Pontchartrain.

    'My concern is that they have learnt to shoot at divers in wetsuits who have simulated terrorists in exercises. If divers or windsurfers are mistaken for a spy or suicide bomber and if equipped with special harnesses carrying toxic darts, they could fire,' [accident investigator Leo Sheridan, 72] said. 'The darts are designed to put the target to sleep so they can be interrogated later, but what happens if the victim is not found for hours?'

    What, indeed...

    On the "Chimpanzee Genome Consortium": Gretchen says that anything involving the words "chimpanzee" and "consortium" creeps her out.

    Why?

    Well, there is this:

    "This is the consortium route," she said, "based on our assumptions about the expedition. They're going in big - thirty or more people, a full-scale undertaking.

    If you haven't read Congo, you may not know where this is going. Here's a hint:

    Once alone, away from the others, he found himself staring into the clear running water and considering the possibility that he might be wrong. Certainly primate researchers had a long history of misjudging their subjects.

    OK, you definitely need more than a hint:

    Something struck him lightly in the chest. At first he thought it was an insect but, glancing down at this khaki shirt, he saw a spot of red, and a fleshy bit of red fruit rolled down his shirt to the muddy ground. The damned monkeys were throwing berries. He bent over to pick it up. And then he realized that it was not a piece of fruit at all. It was a human eyeball, crushed and slippery in his fingers, pinkish white with a shred of white optic nerve still attached at the back.

    Yep, that's creepy.
