Rockefeller researchers discover a biological clock within a clock
Eurekalert ^ | 1/12/06 | Joseph Bonner

Posted on 01/13/2006 7:25:46 AM PST by Michael_Michaelangelo

Just as a pocket watch requires a complex system of gears and springs to keep it ticking precisely, individual cells have a network of proteins and genes that maintain their own internal clock -- a 24-hour rhythm that, in humans, regulates metabolism, cell division, and hormone production, as well as the wake-sleep cycle. Studying this "circadian" rhythm in fruit flies, which have genes that are similar to our own, scientists have constructed a basic model of how the cellular timekeeper works. But now, a new report in this week's issue of the journal Science turns the old model on its head: By providing a glimpse into living cells, Rockefeller University researchers have uncovered a previously undetected clock inside the circadian clock. The scientists made the finding with a rarely used technique called FRET, which enabled them to follow circadian proteins over an extended period of time and watch the clock as it ticks away in a living cell.

The movie allowed them to follow the interactions between Period and Timeless with a resolution never before possible. 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. "Some switch is thrown at six hours that lets the complex explode. The proteins pop apart and roll into the nucleus," Young says. "Somehow, implanted within the system is a timer, formed by Period and Timeless, that counts off six hours. You have a clock within a clock." He notes that this precise timer shows how carefully orchestrated interactions between proteins really are.

Only if it will put me in a protected category and shower me with government grants.

I do not agree that you are qualified to tell professed Christians belonging to any Christian Church that they are not, in fact, Christians.

Comprehension....


I told no one anything.

I posted Scripture and asked questions.

Just like FOX: I report, you decide.

I was a SF fan myself, in my younger days; then I discovered the REAL world was complex enough for me to try to understand! ;^)

It is not true that other possibilities are ignored and rejected on their face.

Are there other possibilities?

Ping us when you get God's exact construction methods figured out to anywhere near the kind of detail that the biologists have already achieved.

That is the job of eternal-life folks, aka creationists.

This -> eternal-life <- should have 'evolved' by now. Merely staying alive is a WHOLE lot simpler than all this reproducing we see goin' on all the time.

(It musta been REAL rough for them first critters, tryin' to stay alive long enough to evolve the reproduction thingies.)

No, you said you saw a conflict between their professed Christianity and certain quotes from the Bible.

Me: "It's my understanding that most professional scientists (including those on Free Republic) are also believing Christians (or Jews) of some brand.
I see no conflict myself."
 
You: "I do.....[followed by various quotes and a question]"

But, from intro Astronomy class I took last year, I read about Big Bang, not God pointing his finger and *poof* the universe came into being.

You mean using THIS formula??

E=Mc2?


Re-arranging we get...

M=E/c2

NOW the question is: From Where did the ENERGY come?

What kind of evolutionists believe in resistance to death?

You may want to think on that for a while.

Matthew 7:7  "Do not judge, or you too will be judged.
 
 
Ah yes; the great verse that is used by those who do not wish to be judged by mere humans.
 
Too bad they tend to ignore others...
 


NIV Luke 12:57
  "Why don't you judge for yourselves what is right?
 

NIV 1 Corinthians 5:12-13
 12.  What business is it of mine to judge those outside the church? Are you not to judge those inside?
 13.  God will judge those outside. "Expel the wicked man from among you."
 
 
NIV 1 Corinthians 6:2-4
 2.  Do you not know that the saints will judge the world? And if you are to judge the world, are you not competent to judge trivial cases?
 3.  Do you not know that we will judge angels? How much more the things of this life!
 4.  Therefore, if you have disputes about such matters, appoint as judges even men of little account in the church!
 
NIV 1 Corinthians 10:15
  I speak to sensible people; judge for yourselves what I say.
 

NIV 1 Corinthians 11:13
  Judge for yourselves: Is it proper for a woman to pray to God with her head uncovered?

Yup, you are right!

I certainly DID say that I saw a problem.

I did NOT say anyone else was NOT a Christian if they saw it differently.

Complete the thought .... Matthew 7:1-5 ... why does everyone love to quote verse one and leave out the rest?

Would you let a convicted, time served, released child molester babysit your children? How about if he told you he was reformed?

And all these proteins and molecules decided to be friends in the primordial ooze, all on their own. No intelligent design involved at all! (/sarcasm off)

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

By kings made quiet
And priests made wise
They love better the heat of their hearths
Than the light of her eyes.

" This -> eternal-life <- should have 'evolved' by now. Merely staying alive is a WHOLE lot simpler than all this reproducing we see goin' on all the time."

Who says it is "simple"? Only to those who believe in magic and supernatural it is "simple". To the rational people, it is anything but simple. Yes, life should "simply" evolve into eternal, but "life" itself is made up of cells that die constantly. Eventually, a body cannot replenish all those dead cells, thus "life" ends.

"(It musta been REAL rough for them first critters, tryin' to stay alive long enough to evolve the reproduction thingies.)"

Indeed the first, most primitive forms of life are ASEXUAL. Meaning they don't reprouduce in a traditional sense. Get a grip, please.
