How kinesin actually moves

Horizontal grid lines (dotted lines) are spaced 8 nm apart. Data were median-filtered with a window width of 60 ms. b, Normalized histogram of pairwise distances between all pairs of data points in this record, showing a clear 8-nm periodicity. c, Normalized power spectrum of the data in b, displaying a single prominent peak at the reciprocal of 8 nm (arrow). d, Variance in position, averaged over 28 runs at 2 microM ATP (dots), and line fit over the interval 3.5 ms to 1.1 s. The y-intercept of the fit is determined by equipartition,  left fencex2right fence = kT/alpha, where alpha is the combined stiffness of the optical trap and bead–microtubule linkage. The rapid rise in variance at short times reflects the brownian correlation time for bead position.

Recently, Carl Zimmer made a criticism of the computer animations of molecular events (it’s the same criticism I made 8 years ago): they’re beautiful and they’re informative, but they leave out the critical aspect of stochastic behavior that is important in understanding the biochemistry. He’s talking specifically about kinesin, a transport protein which the animators …

I get email: Still looking for an obliging geophysicist

This guy wrote to me back in September, when he was regurgitating creationist rationalizations for the global flood, at the behest of wacky ol’ Walt Brown. He called me again this morning and sent me another missive. On the phone, he sounded a bit miffed that I didn’t immediately remember who the heck he was, …

Polls of the American public are so depressing

AP-GfK-March-2014-Poll_SCIENCE

Especially when they poll them on science knowledge. An AP poll on science doesn’t surprise me at all. At least it’s good to know that finally, after 50+ years of hard lobbying and information campaigns, it has finally sunk in that smoking causes cancer. What isn’t so good are the numbers on evolution and climate …

Teaching confidence rather than knowledge

Dunning-Krueger strikes again! A survey of Oklahoma students showed that their high school biology course caused a net reduction in their knowledge of evolution. The study, conducted by Tony Yates and Edmund Marek, tested biology teachers and students in 32 Oklahoma public high schools via a survey the pair called “the Biological Evolution Literacy Survey.” …

Here’s something else oppressing Ken Ham

tiktaaliklimb

He hates Tiktaalik. He hates it so much he even has a hard time spelling its name correctly. Tikaalik is again being popularized through the new PBS series "Your Inner Fish.” it’s really a desperate con job on the part of evolutionists who can’t defend their evolutionary fictional story. He actually surprises me a little …

Ken Ham gets his wish

Poor ol’ Ken has been feeling oppressed lately — there was that Noah movie (unbiblical!) and this Cosmos series (godless!), and it was so unfair. Where was the Cosmos show that gave equal time to the one true Biblical story of the universe? He gets his wish at last. Here it is, Creationist Cosmos. Creationist …

No! Not the list of stumpers again!

There’s a common tactic used by creationists, and I’ve encountered it over and over again. It’s a form of the Gish Gallop: present the wicked evolutionist with a long list of assertions, questions, and non sequiturs, and if they answer with “I don’t know” to any of them, declare victory. It’s easy. We say “I …

How embarrassing

Republicans in Minnesota are endorsing Aaron Miller as a candidate to challenge Tim Walz, a Democrat in the first congressional district. What’s embarrassing about it is that Miller is a creationist kook. Miller likes to repeat a story on the campaign trail about his daughter being driven to tears because her teacher taught evolution that …

Today is the 10th Annual Paul Nelson Day!

I think the appropriate way to celebrate is to do nothing at all, but just to pretend to have a big party. Paul Nelson Day commemorates the fabulous concept of Ontogenetic Depth, a metric that Paul Nelson invented and presented at the 2004 Society for Developmental Biology meetings — he claimed that it was a …

Islam and science are compatible, as long as you cut out the bits of science you don’t like

I visited Brighton, once. I took a pleasant stroll down along the beach, dipped my toe in the water, and I liked it! Therefore, my current physiological state is entirely compatible with swimming the English Channel, and how dare anyone criticize my lack of swimming practice and stamina and strength as somehow incompatible with being …
