Well, allegedly. You think sophisticated man-made computers and the amounts of data they store are a lot, just wait until you find out what’s inside you.

Looking at both digital memory and analog devices, the researchers calculate that humankind is able to store at least 295 exabytes of information. (Yes, that’s a number with 20 zeroes in it.)

Put another way, if a single star is a bit of information, that’s a galaxy of information for every person in the world. That’s 315 times the number of grains of sand in the world. But it’s still less than one percent of the information that is stored in all the DNA molecules of a human being.

If you found a disc drive in the middle of the jungle, you’d just know that it was man-made. But we have something far more capable (and small) inside of us, but that just worked itself out on its own. Riiight.

One of the podcasts I listen to is Heading Right Radio with Ed Morrissey of “Captain’s Quarters”. He gets some great interviews, and last week (I’m behind in my podcast listening) he got Dinesh D’Souza and they talked about D’Souza’s book “What’s So Great About Christianity”. Fresh from his debate at King’s College with Christopher Hitchens, D’Souza covers a number of interesting topics from his book, including the truth about the Gallileo’s persecution, the limits of reason, why the recent increase in atheist apologetics, the supposed “war” between science and religion, thank-you letters to Portugese inquisitors, and other light topics. >grin<

In February, 2008, Ben Stein (yes, that Ben Stein) is coming out with a movie that exposes the scientific community’s rather non-scientific silencing of those not towing the line.

Evolution – and the explosive debate over its virtual monopoly on America’s public school classrooms – is the focus of the film “Expelled: No Intelligence Allowed.”

In the movie, Stein, who is also a lawyer, economist, former presidential speechwriter, author and social commentator, is stunned by what he discovers – an elitist scientific establishment that has traded in its skepticism for dogma. Even worse, say publicists for the feature film, “along the way, Stein uncovers a long line of biologists, astronomers, chemists and philosophers who have had their reputations destroyed and their careers ruined by a scientific establishment that allows absolutely no dissent from Charles Darwin’s theory of random mutation and natural selection.”

“Big Science in this area of biology has lost its way,” says Stein. “Scientists are supposed to be allowed to follow the evidence wherever it may lead, no matter what the implications are. Freedom of inquiry has been greatly compromised, and this is not only anti-American, it’s anti-science. It’s anti-the whole concept of learning.”

Nice to see someone taking on this issue in what looks to be a funny and informative, Ben Stein sort of way.

CBS News reports on new discoveries that are rewriting what evolutionists have thought about who begat whom.

Surprising research based on two African fossils suggests our family tree is more like a wayward bush with stubby branches, challenging what had been common thinking on how early humans evolved.

The discovery by Meave Leakey, a member of a famous family of paleontologists, shows that two species of early human ancestors lived at the same time in Kenya. That pokes holes in the chief theory of man’s early evolution — that one of those species evolved from the other.

And it further discredits that iconic illustration of human evolution that begins with a knuckle-dragging ape and ends with a briefcase-carrying man.

Scott Ott at ScrappleFace nails it as usual.

Far from casting doubt on Darwin’s theory, experts say that the lack of evidence and contradictory discoveries have helped to build “a consensus of certainty in the field.”

“Finding little physical evidence to substantiate the theory only means there must still be a great deal of supportive evidence out there to be found,” said an unnamed editor of the journal Nature, which plans to publish a paper on the African skulls this week. “The more we realize how little we know, the more certain we are that we’re right. As I once read in a scholarly paper somewhere, ‘faith is the assurance of things hoped for, the conviction of things not seen’.”

And not the robotic kind.

Around the world, a handful of scientists are trying to create life from scratch and they’re getting closer.

Experts expect an announcement within three to 10 years from someone in the now little-known field of “wet artificial life.”

“It’s going to be a big deal and everybody’s going to know about it,” said Mark Bedau, chief operating officer of ProtoLife of Venice, Italy, one of those in the race. “We’re talking about a technology that could change our world in pretty fundamental ways—in fact, in ways that are impossible to predict.”

What’s interesting to me is how they plan to solve some problems.

One of the leaders in the field, Jack Szostak at Harvard Medical School, predicts that within the next six months, scientists will report evidence that the first step—creating a cell membrane—is “not a big problem.” Scientists are using fatty acids in that effort.

Szostak is also optimistic about the next step—getting nucleotides, the building blocks of DNA, to form a working genetic system.

His idea is that once the container is made, if scientists add nucleotides in the right proportions, then Darwinian evolution could simply take over.

“We aren’t smart enough to design things, we just let evolution do the hard work and then we figure out what happened,” Szostak said.

This will be an interesting test of the evolution theory, but we’re years away from that.

Or ever have.

Biologists have uncovered a deep link between lifespan and cancer in the form of a gene that switches off stem cells as a person ages.

The critical gene, already well known for its role in suppressing tumors, seems to mediate a profound balance between life and death. It weighs the generation of new replacement cells, required for continued life, against the risk of death from cancer, which is the inevitable outcome of letting cells divide. To offset the increasing risk of cancer as a person ages, the gene gradually reduces the ability of stem cells to proliferate.

The new finding, reported by three groups of researchers online Wednesday in Nature, was made in a special breed of mice that lack the pivotal gene, but is thought likely to apply to people as well.

The finding indicates that many of the degenerative diseases of aging are caused by an active shutting down of the stem cells that renew the body’s various tissues, and are not just a passive disintegration of tissues under life’s daily wear and tear, as is often assumed.

“I don’t think aging is a random process – it’s a program, an anti-cancer program,” said Dr. Norman E. Sharpless of the University of North Carolina, senior author of one of the three reports.

I find this article interesting on a number of levels. Let’s start with the idea that this scientist says that aging is not a “random process”, rather that it is “an anti-cancer program”. This, to me, really stretches the credulity with which one must view evolution. Somehow, over the years of random changes, a program emerged through natural selection. But since the vast majority of mutations result in a degradation of the organism, the odds of such a program being written are astronomical, on top of all the other odds-beating events like the formation of life itself.
