Piotr (and KS, DNA_Jock, VS, Z et al) and “compensation” arguments vs the energy audit police . . .

It seems to be time to call in the energy audit police. Let us explain, in light of an ongoing sharp exchange on “compensating” arguments in the illusion of organising energy thread. This morning Piotr, an objector (BTW — and this is one time where expertise base is relevant —  a Linguist), at 288 dismissed Niwrad: Stop using the term “2nd law” for something that is your private misconception. You’ve got it all backwards . . . This demands correction, as Niwrad has done little more than appropriately point out that functionally specific complex organisation and associated information cannot cogently be explained away by making appeals to irrelevant energy flows elsewhere. Organisation is not properly to be explained on spontaneous Read More ›

Jerry’s Question — Crash Course in Base Pairs and Complementary Strands

Our longtime commenter Jerry several months ago asked a question about DNA (regarding complementary strands). I presume he got an answer by now. At the time, I wanted to respond to his question with this video, but I just never got around to it! But the video would still be incredibly valuable to all our readers. If I showed this video to ID sympathizers, it’s rather easy to persuade them of ID. It’s only about 13 minutes long, but you’ll learn a lot about DNA, chemistry, and ID (indirectly if you know what I mean), and the history of Rosalind Franklin’s contribution. I love the narrator’s fast talking. Slow talking puts me to sleep! [youtube 8kK2zwjRV0M]

VIDEO: A look at the ATP Synthase in action, courtesy Discovery Institute (and Wikipedia)

DI has just released a video on the ATP Synthase in action (HT: ENV): [youtube XI8m6o0gXDY] The blurb at Youtube reads: ATP Synthase is a molecular machine found in all living organisms. It serves as a miniature power-generator, producing an energy-carrying molecule, adenosine triphosphate, or ATP. The ATP synthase machine has many parts we recognize from human-designed technology, including a rotor, a stator, a camshaft or driveshaft, and other basic components of a rotary engine. This machine is just the final step in a long and complex metabolic pathway involving numerous enzymes and other molecules—all so the cell can produce ATP to power biochemical reactions, and provide energy for other molecular machines in the cell. {Added, courtesy commenters below, here Read More ›

A process sequence chart view of the ribosome in action — a guest post by EP

For some months now, I have been having a behind the scenes correspondence with a regular viewer of UD, whom we shall call EP. He works with industrial robots, and has been fascinated by the way the ribosome works as a nano-scale automated machine cell. Accordingly, a process sequence diagram (‘map”) has been developed, based on accessible descriptions of the ribosome in action. The result is a fascinating look at the ribosome as industrial robot work-cell. (The tRNA’s are molecular scale position-arm devices with a universal CCA coupler — yup, the AA bond is universal, it is the loading enzyme that sets up which tRNA gets what AA — to load and click AAs to a protein chain.) So, enough Read More ›

More popcorn: A virtual tour of the cell (and a link to another)

Courtesy North Dakota State U: [youtube YM2X1c4K1x0] (And for those wanting a narrated version of the famous XVIVO vid, cf here.) Remember, we are looking at these videos in light of Denton’s remark of 1985: To grasp the reality of life as it has been revealed by molecular biology, we must magnify a cell a thousand million times until it is twenty kilometers in diameter [[so each atom in it would be “the size of a tennis ball”] and resembles a giant airship large enough to cover a great city like London or New York. What we would then see would be an object of unparalleled complexity and adaptive design. On the surface of the cell we would see millions Read More ›

Popcorn: watching kinesin in action, as we digest that Christmas turkey and pudding . . .

Sometimes, seeing is believing. Here is a nice, short summary of the kinesin microtubule highway “walking truck” protein in action: [youtube lLxlBB9ZBj4] This vid gives a bit of context: [youtube 8RULvE9rw6Y] Especially notice the role played by Brownian motion, and that played by ATP. So, post turkey and pudding vid no 3: ATP Synthase in action: [youtube KU-B7G6anqw] Walking trucks in the cell, fuelled by batteries made in a molecular factory that uses a nanotech motor  . . . And, a highway network that has to go where it is needed, with need for directions — that delivery truck has to know where to go, when! And the best explanation for all of this functionally specific, complex organisation and required Read More ›

News Release: Harvard’s XVIVO Video

News Release: Harvard’s XVIVO Video By William A. Dembski | originally posted November 26, 2007 | updated November 27, 2007 Back in September of 2006 I announced at my blog UncommonDescent that a “breathtaking video” titled “The Inner Life of Cell” had just come out (see www.uncommondescent.com/…/the-inner-life-of-a-cell). The video was so good that I wanted to use it in some of my public presentations, but when I tried to purchase a DVD of it (I sent several emails to relevant parties), I was informed it wasn’t ready (to my knowledge the video is still not available for sale in DVD or any other format — if it were, I would gladly purchase it and encourage others to do so). Moreover, Read More ›

Yet Another Irreducible Complexity No-Brainer — Twisted Ropes

For those who missed it, check out this animation presented by DaveScot.

I find the phenomenon of the DNA supercoiling problem and its biochemical solution even more compelling than examples like protein synthesis and the bacterial flagellum, since twisted ropes are familiar to everyone. This might make for another highly persuasive ID mascot.
