In part 1 of this series, I discussed how shared ion channels in potatoes and mammalian brains exemplify molecular convergence. Such convergence supports the case for intelligent design better than it … more
Ion channels are fascinating structures composed of amino acids embedded within cell membranes. Among other functions, ion channels act as intracellular messengers and make muscle contractions … more
We’re big movie fans in our house and we love to see how our favorites were made. While exploring the “behind-the-scenes” featurettes on our copy of Disney•Pixar’s Brave I … more

Dr. Fuz Rana reports on phase 2 of the Encode project, biochemical research that he calls the most important of his lifetime.
UPDATE June 2013: This updated version of Dr. Rana's talk includes … more
For several decades, biochemists thought a vast proportion of most organisms’ genomes consisted of junk—DNA sequences that once had value but decayed into nonfunctional elements as a … more

They prey on their own kind. Some might call it cannibalism, but it’s the only way they can survive. Indeed, the zombie apocalypse is here.
So-called “zombies” exist … more
A few days ago I wrote about the ENCODE project and the new recognition that, at minimum, 80 percent of the human genome consists of functional DNA elements. Despite some skeptics’ complaints … more
“I think that the formulation of [DNA’s] structure by Watson and Crick may turn out to be the greatest developments in the field of molecular genetics in recent years.” … more
A few days ago I wrote about a recent advance in biotechnology that highlights the incredible information-carrying capacity of DNA. This biomolecule can store information, because it is an … more
“When I get a little money I buy books; if any is left I buy food and clothes.”
I love books. As soon as you walk into our house, you will see that this is true. … more
RTB’s Fuz Rana calls it the biggest discovery of his lifetime as a biochemist.
A massive new DNA research project called ENCODE has dramatically increased understanding of the human genome and … more
A few days ago I wrote about the molecular rotary motor F1-F0-ATPase, arguing that its supramolecular architecture and operation bear an uncanny similarity to a man-made machine. This similarity … more
I don’t like to be criticized—not. one. bit. But if I am honest with myself, there is almost always some measure of validity to the critical comments directed my way.
As my friend, who is … more
A few days ago, I described new work that demonstrates the optimal design of the cell’s metabolism. Many other features of the cell’s chemistry are optimized as well. In fact, optimality … more
One of the biggest shocks I experienced when we moved from Cincinnati to the Los Angeles area thirteen years ago was the traffic—and the complexity of the Southern California freeway … more
In a few days, fervent fans will scatter to the nearest theater to catch one of the most anticipated movies of the summer: The Amazing Spider-Man.
An exciting little detail about this franchise … more
