New Marathon World Record

Well, running great Haile Gebrselassie of Ethiopa broke Paul Tergat’s four-year-old marathon record of 2:04:55 at Berlin this morning with an amazing 2:04:26. Details here and here.
This works out to an average pace of 4:44.8 per mile or 2:56.9 per km over 26.2 miles (42.2 km). Geb’s sustained energy output is mind boggling compared to that of the average 34 year old (or just about any human runner for that matter).

Another Orb Weaver

One of my spawn attempted to take a photo of our household araneidid. He eschewed the flash because he didn’t want to frighten the spider, so the photo is blurred. However, the colors and patterns of the charlotte can be discerned and are kinda striking.

Friday Flippancy: The Verse of the One RNA and Discovery Institute Follies

Gene Expression’s Razib used a catchy little title for the article in which he referenced DNA Unraveled by Colin Nickerson for the Boston Globe. How overarching the role of RNA will be for the regulation of gene expression throughout the genome is still up for grabs, but one can’t deny that there’s fascinating and uncharted territory to be explored.
Predictably, the folks at the Discovery Institute leapt all over Nickerson’s article as further implication that complexity = Intelligent Design, and the old “scientists don’t know everything therefore the theory of evolution is not true” canard.

Friday Flower Porn: Pump Kin!

Er, make that just pumpkin. This little critter was caught crimson fisted packing her saddle bags with pumpkin pollen recently. I wonder if they fly around looking for some nutmeg and cinnamon, too?
PumpkinFlowerBee1.jpg
In any case, in spite of the numerous pumpkin blossoms that have been produced in the garden over the past couple of months, not a single pumpkin has emerged. Of course, this particular pumpkin patch was a bit of a lark, coming from the seeds of last year’s jack-o-lantern. My guess is that this particular variety isn’t particularly fertile, in spite of the bee’s knees.

USB 3.0

This week’s Electronic Engineering Times features a short article on the upcoming USB 3.0 spec. The main highlight is a target transfer rate of 4 Gigabits/second (10 times the current rate) providing usable data at 300 Megabytes/second. This rate would challenge IEEE 1394 (AKA FireWire). USB 3.0 is being referred to as “Super Speed USB” and will be “hardware agnostic” according to the article, meaning it could be implemented over copper or optical cabling.
This third variant on the USB theme will adopt a new physical layer, splitting data and acknowledge signals onto separate paths. On the downside, it is likely that USB 3.0 will require a reduction in maximum cable lengths from 5 meters to 2 meters.
The USB crowd is claiming that 3.0 will supplant FireWire, but the FireWire folks themselves are hard at work extending the current 800 Megabit/sec transfer to 3.2 Gigabits/sec. The FireWire spec is due out next year while USB 3.0 silicon is expected in 2009.

Meet my cousins, the beech trees

I mentioned in my previous entry the sense of transcendence I feel when I observe the green light passing through a tree’s leaves. My neighborhood woods on Princeton Ridge is full of tall trees, including beeches which are my favorite arboreal species. Part of that sense of wonder stems (har) from my knowledge of the inter-relatedness of the tree and myself, my lack of chlorophyll notwithstanding.
John Stiller of East Carolina University contends that we humans are more closely akin to plants than we are to fungi. The following article from ABC Science (that’s the Australian Broadcasting Corporation) outlines some of the reasons that Stiller thinks we need to move beyond molecular sequence-based phylogenetics when comparing plants and animals
As a former botany major and current aficionado of flower pornography, I feel vindicated that someone acknowledges the kissing cousin relationship between the beech trees and me…not that I hug them or anything.

Battling Rainbows! John Keats vs. James Thomson Poetry Smackdown

Richard Dawkin’s Unweaving the Rainbow: Science Delusion and the Appetite for Wonder is on my active reading docket. The book has been around for a while (published in 1998), but it’s proving to be a most enjoyable discovery as I continue to read it. So far, I concur with complete reviews’ take on the book. It is a marvelous paean to the majesty and artistry of science. Dawkins’ sense of wonder very much resonates with my own – that feeling of transcendence when I look at light shining through green leaves or the transformations of calculations that are revealed as a colorful abstract collection of molecules on a computational chemist’s monitor screen.
Dawkins derives the title of the book from John Keats’ poem, Lamia. In the opening paragraph of “Barcodes in the Stars” in Unweaving the Rainbow, Dawkins recounts a gathering in 1817 at the studio of artist Benjamin Haydon:

The Scent of a Man…or a Monkey.

I previously confessed that I subscribe to that glossy hardcopy glut of advertising called Vanity Fair. Invariably, the mag contains photo spreads of ripple-ab’ed dudes hawking various men’s cologne. All this to mask delicious or stinky or neutral 5alpha-androst-16-en-3-one (androstenone); based on one’s genetic variation in the olfactory receptor that binds this steroid, it will smell sweet or icky or not at all. Razib at Gene Expression already covered the recent article in Nature – please see a world of sensory difference.

I Get Mail: Arachnoterror!

Found scuttling around in my docbushwell at gmail inbox:
image003.jpg
image001.jpg
image002.gif
Needless to say, I was slightly disturbed when greeted with those images. My learned correspondent wrote the accompanying letter:

Dr. Bushwell:

My research has confirmed existence of several genera of the wolf spider Pardosa (Araneae, Lycosidae), such as the rabid wolf spider Rabidosa (Araneae, Lycosidae) and the oriental wolf spider Passiena (Lycosidae, Pardosinae). However, I have found no evidence of the FUCKING WOLF SPIDER! genus documented in Science Blogs. Ahem. Isn’t science supposed to be about facts?

Nevertheless, despite your unsupported claim, I’ve decided that FUCKING WOLF SPIDER! would be an excellent name for a band…probably a really bad, thrash metal hair band. Look for our upcoming CD release, “In Your Fucking Tent” featuring the soon-to-be-hit, head-banging ballad “While You Sleep.”
Sincerely yours,
R.M.

Coincidentally (or not), I had just read Arachnid Serendipity courtesy of The Indigestible, a noteworthy compendium of borborygmi to be found in the Refuge’s “Skepticism and General Agitation” blog roll. Warren’s description (augmented with picturesclose-up pictures) of his encounter with an Arizona brown spider had me writhing in my chair brushing away phantom legs and probing pedipalps.
Pardon me while I turn into a gibbering, quivering lump of phobic protoplasm.

LOLTHEORISTS

I didn’t shuffle through the digital shoe box of photos for flower porn today, so I’m offering something else.
A few posts back, LOLTHULHU made an appearance. It’s a parody of LOLCATS. With regard to the latter and the former, here’s what the blog formerly known as the Table of Malcontents (now Ectomo) had to say:

Is there anything more loathsome, more indicative of the rife idiot stupidity of the Internet than the LOLCats meme? The endless repetition of the exact same joke (photograph of surprised cat + implausible misspelling) done over and over and over again. Have you ever opened Photoshop, inserted a picture of your cat and then superimposed a sentence beginning with “O HAI” in a bold white Impact font? Congratulations. You are a lowest common denominator idiot and, quite frankly, you’re lucky Stalin ruined that whole gulag idea for everyone.
On the other hand, LOL Cthulhu? Now there’s a meme we can all get behind. How long, though, before someone soils even this fine thing by ‘cleverly’ mating this hilarious, tentacled genre with its retarded feline cousin, unleashing the bastard spawn LOLCathulhus upon the world? God damn you, whoever you are.

Well, there is another unholy meme that has been unleashed as of May 2007:
LOLTHEORISTS.
Some of you may be familiar with this, but it’s new to me. Hat tip to my correspondent in Dublin for passing the link along and also to The Dude in San Diego for the link to Malcontents/Ectomo.
I’d be hard pressed to name a favorite, but I snickered at the following.

Another Lactivist-Scientist-Mom Here – It’s Not Just Facebook.

Speaking as a mother who breastfed both of my kids and was a card-carrying member of LaLeche League (an uneasy relationship since I worked outside the home but valuable all the same for many other reasons), I figured I’d weigh in on this, but not from the Facebook angle. There are plenty of other offerings among my SciBlings on the Facebook debacle, and I am sure you can find them via the main page so I am not linking them here. I can’t say I am surprised at FB’s reactionary response to the photos of the mother in question. Breastfeeding is ridiculously sexualized in the US.
So here I offer you Exhibit B:
Bill Maher made a pig of himself (not surprisingly) when he weighed in recently on public breastfeeding as Katharine Mieszkowski reports in Bill Maher: “Don’t show me your tits!” via Salon’s Broadsheet. Since not all have access to the now gated community of Salon, here’s the text. I hope Ms. Mieszkowski will forgive me for reprinting this rather than just providing a link. There’s also a video of Maher’s idiocy in the Salon piece.

HBO’s Bill Maher is a self-professed libertarian, except when it comes to moms agitating for the right to breast-feed in public. Then he’s all about telling us what to do with our bodies and babies.
In a segment on “Real Time With Bill Maher” on Sept. 14, which inflamed lactivists the Web over, Maher ridiculed a recent nationwide nurse-in to object to Applebee’s treatment of a breast-feeding mom in Kentucky. (As we mentioned last week, you can catch some choice video of the Applebee’s nurse-in here. One highlight: adults brandishing bananas put blankets over their heads to demonstrate that infants might find it challenging to eat that way, too.)
Among Maher’s digs against the lactivists, he compares breast-feeding in public to masturbating in public: “Next thing, women will be wanting to give birth in the waterfall in the mall,” he jokes. He carps that these moms are just “too lazy” to plan ahead or cover up. And what do these mothers really want, according to Maher? To feed their hungry children and avoid crying fits in public, maybe? Nah, says Maher, what they really want is attention! Yep, what they really, really want is guys like Maher looking at their boobs.
But Maher knows one place where food and breasts mix: Hooters! Get it? Hooters. Yuk, yuk! A joke that really only proves the lactivists’ point that breasts are considered 100 percent socially acceptable when they’re intended to sexually titillate lascivious middle-aged men but “Ewww, gross” when they’re used to feed a kid.
I really would have been happy to make it through life without ever writing the words “Bill Maher” and “masturbating” in the same sentence, but as they say on Fox News: “We report. You decide.” Here’s the video; the nursing fuss comes at the end:
Broadsheet prediction: Forget Applebee’s. The next lactivist boobalicious action will take place outside the studios of “Real Time With Bill Maher,” uniting thousands of moms with babies at the breast, in a lactating throng not seen since Manila. Poor Bill Maher. To get to work, he’ll have to stumble by, covering his eyes with both hands to avoid possibly catching a glimpse of — horrors! — a nipple.
Better still, here’s a Broadsheet contest: The first daring lactivist who actually infiltrates the set of “Real Time With Bill Maher” and disrupts the show with a one-woman nurse-in wins my voice on the outgoing message of her home answering machine or voice-mail. I may be no Carl Kasell, but I can promise dulcet tones, too, and I’ll even throw in the lactivist nursing slogan of your choice; pick your favorite here.

Addendum:
Here’s the New Rules clip.

The (NP)Y’s and Wherefores of Stress and Obesity

When I find myself in times of trouble
Ben and Jerry’s comes to me
Snarfing Chunky Monkey so sweetly, so sweetly.

When stressed, some folks barely eat and consequently lose weight. Others, including myself, reach for high-fat-high-sugar (HFS) foods in an attempt to ameliorate the angst. Although the connection between stress and overeating is not fully understood, the evidence until recently focused on centrally acting (brain & spinal cord) mechanisms, e.g., hypothalamic control of food consumption and metabolism.
However, Lydia Kuo et al. (1) reported recently in Nature Medicine that stress-triggered release of neuropeptide Y (NPY) can stimulate angiogeneis (formation of new blood vessels) in the periphery, i.e., other places in the body than the brain and spinal cord. The researchers also demonstrated that NPY stimulates creation and differentiation of new fat cells (adipogenesis). NPY evidently binds to its receptor (or one of its receptors), NYP2R – a G-protein coupled receptor, and gets the big fat ball rolling.

Cthulhu Fhtagn Peruvian Meteorite

Steinn (Dynamics of Cats) reports that Mars Invades Peru.
This must be smack-dab in the middle of physical-type scientists’ radar screen since my Rocket Scientist(tm) friend sent a similar blurb from Yahoo News.
I expect Scully and Mulder have been called in to investigate. Rocket Scientist(tm) mysteriously alluded to the Colour Out of Space in his e-mail, signing off with the baffling words:
Ph-nglui mglw’nath Cthulhu R’lyeh wgah’nagl fhtagn.
The Thing From Beyond the Stars is either a meteorite that released volatiles or a man-made object containing similar gaseous substances as Steinn rationally suggests. Rocket Scientist ™, who has experience in these matters, likewise remarked that a man-made object was a possibility. Now my friend is also usually quite measured, but on occasion, he claims that he is the reincarnation of Abdul Alhazred. So I’m worried. Maybe – just maybe – Cthulhu Fhtagn Cheezburger.
My hat’s off to Steinn for that masterful alliteration and to gwyn for directing me to the LOLTHULHU site.
—————–
Footnote:
Purchasing that collection of Lovecraft short stories the weekend before last wasn’t such a great idea. I blame Warren for spinning me off on a Lovecraftian trajectory
Note added in proof.
LOLTHULHU was previously cited on Pharyngula. I should have known.

No Gloopy Pirates Govoreeting Here, O My Droogs!

Once again, my brothers and sisters, it is that grazhny Talk Like a Pirate Day. What hound-and-horny chepooka is this, I ask you? That PZ chelloveck and other SciBling lewdies Corpus Callosum, Grrl Scientist, and Dr. Free-Ride guff away when they slooshy Pirate. I say “Yarbles!” to that. There should be a “Govoreet Like a Droog Day.” I think that would be real horrorshow.

Psychotropic Walls

Via Technovelgy – Where Science Meets Fiction, here’s an article on a wild display surface upon which small panels move with precision and “ripple,” creating strange, almost biologically protoplasmic motion:
HypoSurface Walls Are Full of Life.
Bill Christensen, the author of the Technovelgy article on HypoSurface notes that this technology is a close approximation of science fiction writer J.G. Ballard’s warped domiciles:

HypoSurface is a pretty good implementation of the plastex walls in J.G. Ballard’s psychotropic houses from his 1960′s Vermillion Sands stories:
It was a beautiful room all right, with opaque plastex walls and white fluo-glass ceiling, but something terrible had happened there. As it responded to me, the ceiling lifting slightly and the walls growing less opaque, reflecting my perspective-seeking eye, I noticed that curious mottled knots were forming, indicating where the room had been strained and healed faultily. Deep hidden rifts began to distort the sphere, ballooning out one of the alcoves like a bubble of overextended gum.

Here’s a clip:

More examples may be found on the HypoSurface web site. This company is based in Cambridge MA. Perhaps its location explained why the surface of Spring Street was so pocked and wavy.

A Sale of Two Titles

It was the best of times, it was the worst of times, it was.. Oops. Sorry, already been done. Start again.
The other day I brought up some thoughts concerning the high cost of college textbooks. In the arena of science and engineering there are issues with the fairly narrow audience and resultant low volume, and some difficulties with the used book market. There is, of course, the issue of the publishers. I am going to risk having my snout slapped by biting the hand that feeds me, but hey, I noticed something the other day that has my head spinning anyway.

Language Trends in Embedded Systems Programming

The latest Embedded Systems Design features an overview of their annual comprehensive programmer’s survey. ESD (an unfortunate acronym for a hardware journal) has offered the same survey for the past few years to engineers and programmers in both the USA and Europe, seeking info on their current and anticipated needs, projects, tools, and the like (N>1000 for the past three surveys). There are many useful tidbits in here but one in particular caught my eye, and that’s the trend in development languages used.

Hitchens’ Supreme Sense of Humor

I concede. As self-deprecatory as I can be, I am left in the dust, gasping and quivering, by the mighty Christopher Hitchens who aptly displays the gloriously superior sense of humor that is characteristic of the human male. I am humbled, Mr. Hitchens. My hat’s off to you.
Hitchens_mudmask.jpg
In the latest Vanity Fair, Hitchens writes about his experience at the spa of the Four Seasons Biltmore Resort in Santa Barbara, CA: On the Limits of Self-Improvement, Part I.
It’s an entertaining – and funny – article on the micro-economy of self-improvement. Be sure to check out the slide show!

The High Cost of College Textbooks

We’re a couple weeks into the semester and the ever-popular subject of the cost of textbooks has raised its head. Along with my students, I often wonder why they shell out so much for these works. I think there are several things at play here, but first a little background: I’ve been teaching at the college level for over 25 years and I’ve written a few textbooks myself, for two different publishers: West and Delmar/Thomson Learning (including the ever-exciting Op Amps and Linear Integrated Circuits mentioned on the sidebar, complete with color-coordinated matching laboratory manual). The thoughts that follow are my own and do not necessarily represent those of my publishers, my college, or college bookstore.
