All molecular interactions within cells are interesting. The complexity, coordination, and beauty is awe inspiring.
If there is no God, then Nature does one hell of an imitation.

The article concludes: Young and Meyer, who's now a postdoctoral researcher at Columbia University, have yet to figure out exactly how the timer works, but its discovery opens up the door to a whole new suite of questions. "How does this interval timer tick? Is it made from additional proteins? Is this the only such timer in the circadian clock? Each of these questions are ahead of us," Young says. "A couple of years ago, we had identified lots of genes and had this sweeping picture of how circadian clocks work. But this indicates that there are much more formidable properties of the system that were overlooked."
All I can say is how awesome and marvelous the Lord God is.

FRET?
... So he turned to a technique invented in 1948, called fluorescence resonance energy transfer; FRET gauges interactions between proteins by fluorescently tagging them and measuring how they react to different wavelengths of light. But although the technique can provide useful information, it's so complicated that researchers rarely use it. And no one had ever thought to use it to follow proteins in a single cell for an extended period of time...

"Somehow, implanted within the system is a timer. . .that counts off six hours. . . .This precise timer shows how carefully orchestrated interactions between proteins really are.
It's a FESTIVUS Miracle!
It's amazing what random, non-intelligent, lack-of-design is capable of accomplishing.
To: Michael_Michaelangelo
Cool! I wonder who designed that?

No one designed it. It just happened. There is no designer and no beginning. The evolutionists will explain it in greater detail. :)

Intelligent design would be simpler than the mess we actually have, really.

They discovered that, rather than randomly colliding, the two proteins bind together in the cytoplasm almost immediately and create what Young and Meyer refer to as an "interval timer." Then, six hours after coming together, the complexes rapidly break apart and the proteins move into the nucleus singly, all of them within minutes of each other. Why, I'll bet there's a team of tiny angels that push the proteins around just so.

Intelligent design would be simpler than the mess we actually have, really. Much simpler. Any grade-school dropout could master the subject in a few moments. And many claim to have done so.

Yes. The Larsen cartoon on horse medicine comes to mind. Every condition was followed by the treatment: "Shoot."

Given your tagline

Happy Birthday, Dasher!
