I recently got a Sirius satellite radio installed in my car. I adore it and am espcially hooked on the “Chill” and BBC 1 radio stations. I also love the fact that it carries two separate NPR stations. We barely even have NPR in Houston, so that was a big bonus. However, I thought that by installing the Sirius system in my car, my CD hording habit might somehow be stemmed. This habit has sadly proven to be an as-yet-unconquerable urge, I am disappointed to report.
My three most recent acqusitions (to which, this time, I gave a lot of serious thought before purchasing instead of impulse-buying the shelves dry at Cactus) have been:
The Stranglers – Greatest Hits 1977-1990
…mostly because I’ve had the song “Golden Brown” stuck in my head for almost a week straight and because of the classic lines from “Peaches”: walking on the beaches / looking at the peaches. Regardless, it’s some of the best mod rock out there and was way ahead of its time. My next mission is to get La Folie on vinyl, so if any of you out there have an old LP collection…let a sister know.
…seriously, though, listen to the full-length version of “Golden Brown” here. It will blow your fragile little mind.
Mediaeval Baebes – Mirabilis
…okay, so the cover art looks like something out of a cheap airport bookstore romance novel section, but I’ve always been drawn to choral music. I think it has something to do with being raised Church of Christ.
Ben Folds – Songs for Silverman
…after Rocking the Suburbs, I’m a little disappointed with this latest effort. He really seems to be breaking away from the old-school Ben Folds that I fell in love with circa 1994 and moving dangerously close to the dreadful no-man’s-land of Dave Matthews and Coldplay. Yes, he might just be on his way to becoming that boring and that generic. Thankfully, “Landed” and “Gracie” are two of the saving graces on this album that give me hope for the best.
Next up on the list of purchases – if I can possibly find it anywhere in Houston, otherwise I might be laying down the cash to special order it – is Arc En Ciel Pour Dal Toniens by La Caution. Laugh it up, but French hip-hop is strongly influenced by rai these days, thanks to the large northern African population throughout France. The combination makes for some seriously good music. Check out one of my favorite tracks here.
Alright, it’s Friday night. I’m out.
First, you need to drop everything you’re doing – open-heart surgery, explosives ordnance, hostage negotiation, whatever – and check out the films (filmz?) of Matt Adams. http://whitetigerfilmz.cjb.net/ Your life will never be the same again. His talent will rip your soul from your body when you realize that never in your entire life will you achieve this kind of greatness. You might as well just give up right now.
Like cheesy Highlander films and their (supposed) sequels? Matt Adams. Like still cheesier Chucky films and their sequels? Matt Adams. Like watching a high school dropout who can’t spell the word “anomaly” display the acting range of a toothbrush? MATT ADAMS. Seriously, if you do nothing else today, just bask in the light of his genius for a little while. It will BLOW YOUR MIND.
Second, my father sent me an article today in an e-mail with the subject line “Coolest Thing Ever.” I think, perhaps, that being cooler than Matt Adams might be damn near impossible but this article comes awfully close. Read at your own peril:
I collect tales of parasites the way some people collect Star Trek plates. And having filled an entire book with them, I thought I had pretty much collected the whole set. But until now I had somehow missed the gruesome glory that is a wasp named Ampulex compressa.
As an adult, Ampulex compressa seems like your normal wasp, buzzing about and mating. But things get weird when it’s time for a female to lay an egg. She finds a cockroach to make her egg’s host, and proceeds to deliver two precise stings. The first she delivers to the roach’s mid-section, causing its front legs buckle. The brief paralysis caused by the first sting gives the wasp the luxury of time to deliver a more precise sting to the head.
The wasp slips her stinger through the roach’s exoskeleton and directly into its brain. She apparently use ssensors along the sides of the stinger to guide it through the brain, a bit like a surgeon snaking his way to an appendix with a laparoscope. She continues to probe the roach’s brain until she reaches one particular spot that appears to control the escape reflex. She injects a second venom that influences these neurons in such a way that the escape reflex disappears.
From the outside, the effect is surreal. The wasp does not paralyze the cockroach. In fact, the roach is able to lift up its front legs again and walk. But now it cannot move of its own accord. The wasp takes hold of one of the roach’s antennae and leads it–in the words of Israeli scientists who study Ampulex–like a dog on a leash.
The zombie roach crawls where its master leads, which turns out to be the wasp’s burrow. The roach creeps obediently into the burrow and sits there quietly, while the wasp plugs up the burrow with pebbles. Now the wasp turns to the roach once more and lays an egg on its underside. The roach does not resist. The egg hatches, and the larva chews a hole in the side of the roach. In it goes.
The larva grows inside the roach, devouring the organs of its host, for about eight days. It is then ready to weave itself a cocoon–which it makes within the roach as well. After four more weeks, the wasp grows to an adult. It breaks out of its cocoon, and out of the roach as well. Seeing a full-grown wasp crawl out of a roach suddenly makes those Alien movies look pretty derivative.
I find this wasp fascinating for a lot of reasons. For one thing, it represents an evolutionary transition. Over and over again, free-living organisms have become parasites, adapting to hosts with exquisite precision. If you consider a full-blown parasite, it can be hard to conceive of how it could have evolved from anything else. Ampulex offers some clues, because it exists in between the free-living and parasitic worlds.
Amuplex is not technically a parasite, but something known as an exoparasitoid. In other words, a free-living adult lays an egg outside a host, and then the larva crawls into the host. One could easily imagine the ancestors of Ampulex as wasps that laid their eggs near dead insects–as some species do today. These corpse-feeding ancestors then evolved into wasps that attacked living hosts. Likewise, it’s not hard to envision an Ampulex-like wasp evolving into full-blown parasitoids that inject their eggs directly into their hosts, as many species do today.
And then there’s the sting. Ampulex does not want to kill cockroaches. It doesn’t even want to paralyze them the way spiders and snakes do, since it is too small to drag a big paralyzed roach into its burrow. So instead it just delicately retools the roach’s neural network to take away its motivation. Its venom does more than make roaches zombies. It also alters their metabolism, so that their intake of oxygen drops by a third. The Israeli researchers found that they could also drop oxygen consumption in cockroaches by injecting paralyzing drugs or by removing the neurons that the wasps disable with their sting. But they can manage only a crude imitation; the manipulated cockroaches quickly dehydrated and were dead within six days. The wasp venom somehow puts the roaches into suspended animation while keeping them in good health, even as a wasp larva is devouring it from the inside
Scientists don’t yet understand how Ampulex manages either of these feats. Part of the reason for their ignorance is the fact that scientists have much left to learn about nervous systems and metabolism. But millions of years of natural selection has allowed Ampulex to reverse engineer its host. We would do well to follow its lead, and gain the wisdom of parasites.
