Toxic Cloud May Have a Silver Lining.

Ever since the first Paleolithic Ph.D applied for an NIH Grant, researchers have sought a "silver bullet" that would be effective against the legion of cancers afflicting humanity. Now hope may come from a most unlikely source - a toxic waste site.

The September 2007 issue of Wired Magazine features "Creatures From the Black Lagoon" by Guy Gugliotta - a former Washington Post science writer. This article chronicles how chemists Don and Andrea Stierle stumbled upon potentially useful microorganisms in an abandoned Montana copper mine. Berkeley Pit Lake was born after the open pit operation closed, and water was no longer being pumped out. Minerals leaching from the soil created a highly toxic lagoon. As a result, many an unfortunate creature breathed its last after dropping in for a drink.

But as Jeff Goldblum's character says in Jurassic Park, "Life, uh . . . finds a way." So resourceful BPL microbes fulfilled their Darwinian destiny - and adapted. The outcome was strains of bacteria and fungi that exist nowhere else in the world.

This discovery would have been reward enough for many scientists, but Don and Andrea then took their research in a new direction. Their lifelong passion has been to discover nautical plants and animals with pharmaceutical potential. So they did what any surf loving scientists would do when stuck in Montana - they brought the medical mountain to Muhammad (or Butte, as the locals call it). By subjecting their new bug buddies to the same assays they used with oceanic life, they discovered that some appeared to kill cancer cells. And that - as the white coats at Sloan Kettering will tell you - is a good thing.

The Stierles' work is preliminary, and requires further investigation. Hopefully Big Pharma will now get involved to determine if cancer fighting drugs can be developed from these candidates. I've come up with a few brand names for them: Tumor-Tox, Contamin-Oma, and Berkeley-Balm. And to give their campaign more zing, pharmaceutical sales reps could call on doctors' offices in HazMat suits! (Hey, I'm not married to the last idea - just spitballing here . . .)

Author Guy Gugliotta does a masterful job of presenting this story. His prose is clear and concise, which unfortunately is not the norm in science writing. Many technical journalists fall in love with their own special vocabulary, and forget that we mere mortals can't recite the periodic table by heart. In addition, Gugliotta's compelling imagery captured my imagination. While reading "Creatures From the Black Lagoon", I felt like I was watching a "Nature" TV program. The only thing missing was the sound track.

Gugliotta seamlessly moves his account forward, while covering such diverse topics as Butte's geography and economic history, the Stierles' academic credentials and research, NIH funding, and pharmaceutical drug discovery. The author's narrative flow made me believe that the entire story could have been written in one (really big) paragraph, without losing continuity or comprehension.

I live in New Jersey, whose unofficial nickname is "The Landfill of Opportunity". Thus I am painfully aware of how pollution can damage an environment. This story gives me hope that my state can also find something good in its toxic terrain.

Intelligent Thought by John Brockman

"It will not be possible to rule out the supposition that the process of evolution may be guided by an intelligent design." - Oxford scholar, F.C.S. Schiller, 1897

“Today, the theory of evolution is an accepted fact for everyone but a fundamentalist minority, whose objections are based not on reasoning but on doctrinaire adherence to religious principles."
- James D. Watson.

Intelligent Design
advances the idea that our world was created by a supernatural being. ID proponents believe that this concept is a scientifically valid alternative to Charles Darwin's Theory of Evolution.

In his book Intelligent Thought - Science Versus the Intelligent Design Movement, author John Brockman presents essays on ID by some of the world's top scientists. Contributors include:

Leonard Susskind - the Felix Bloch Professor of theoretical physics at Stanford. He is the author of The Cosmic Landscape: String Theory and The Illusion of Intelligent Design.

Richard Dawkins - an evolutionary biologist, is Charles Simonyi Professor of the Public Understanding of Science at Oxford University. His book The Selfish Gene has generated much discussion among scientists and lay people.

Lisa Randall - is Professor of Physics at Harvard University. She is the author of Warped Passages: Unraveling the Mysteries of the Universe's Hidden Dimensions.

The overwhelming conclusion of the book's contributors is that ID is not science - for three fundamental reasons:

  • A primary rule of science is that natural causes must be attributed to natural phenomena. ID relies on supernatural causality, (i.e. God) which violates this rule. Once you abandon natural causation, you enter into the area of magic or metaphysics - neither of which is science.
  • Intelligent Design has failed to gain acceptance in the scientific community. As a result, it has not been presented in peer-review journals. Such publication is de rigueur for any new theory to be validated.
  • ID is not subject to scientific methodology, so the accuracy of ID's claims cannot be independently authenticated.

The same conclusion was reached in 2005 by the United States District Court, for the Middle District of Pennsylvania in the famous case of Kitzmiller et al. v. Dover Area School District. The court determined that ID was not science, and that teaching it (as science) in the classroom violated The Establishment Clause of The First Amendment. This clause states that "Congress shall make no law respecting an establishment of religion".

In his Introduction, Brockman notes an irony about presiding Judge John E. Jones III: "Readers can rely on the writings of the scientists in this volume (Brockman's book). They can also rely on the words of this lifelong Republican jurist, who was appointed to the court by the current President of the United States (himself a born-again Christian fundamentalist)."

A primary difference between Intelligent Design and the Theory of Evolution is in answering the question - "How did today's life forms get here?" ID advocates state that all life was created abruptly - by a supernatural designer. As as a result, today's flora and fauna have the same form as when they first appeared on Earth. In other words, evolution of species never occurred.

However an overwhelming majority of scientists support an opposing view - the Theory of Evolution, with natural selection and gradual adaptation as its driving forces.

Another tenet of ID is that - Where Evolution is discredited, Intelligent Design is confirmed. This logic is fundamentally flawed, as indicated below:

Item A is red

Item B is blue

If Item C is not red, then it must be blue.

Analysis:
Item C does not have to be blue. It could be yellow, black, white, green, or any other color of the light spectrum. Item C could also be a color that hasn't been discovered yet.

The Wedge Document is an internal memorandum of the Discovery Institute - one of the primary supporters of ID. The Wedge Document was leaked to the Internet in 1999, and was later authenticated by the Institute. Many scientists believe that this document spells out ID advocates' real agenda - to introduce religious doctrine into schools and science. The Wedge Document states "The social consequences of materialism have been devastating. As symptoms, these consequences are certainly worth treating. However, we are convinced that in order to defeat materialism, we must cut it off at its source. That source is scientific materialism. This is precisely our strategy. If we view the predominant materialistic science as a giant tree, out strategy is intended to function as a "wedge" that, while relatively small, can split the trunk when applied at its weakest points. . . Design theory promises to reverse the stifling dominance of the materialistic worldview, and to replace it with a science consonant with Christian and theistic convictions."

Well known proponents of ID include:

Michael J. Behe - author of Darwin's Black Box (1996). One of the arguments of this book is that many biological systems are irreducibly complex at the molecular level. Therefore, they could not have gradually evolved to their current state.

Pervical Davis and Dean H. Kenyon - who authored Of Pandas and People. ID advocates are promoting this as a (required) high school biology text.

Former Pennsylvania Republican Senator Rick Santorum - Wikipedia states "In 2001, Santorum tried unsuccessfully to insert language which came to be known as the Santorum Amendment into the No Child Left Behind bill that sought to promote the teaching of intelligent design while questioning the academic standing of evolution in public schools."

Scott Minnich - whose slogan Teach the Controversy has been praised and condemned by opposing sides. The scientific community's view is that unless intelligent design can be proven to be a valid scientific discipline, then it is inappropriate to compare intelligent design to evolution in a science class. This discussion is better suited for a course in philosophy or religion.

Phillip E. Johnson - a retired UC Berkley Law Professor, is considered by many to be The Father of Intelligent Design. He is the author of Darwin on Trial which argues that science should allow for supernatural explanations.

Intelligent Thought, gives the following bio for author John Brockman - "John Brockman, editor of many books including The Next Fifty Years, Curious Minds, What We Believe But Cannot Prove, and My Einstein, is also the author of By the Late John Brockman and The Third Culture. He is the founder and CEO of Brockman, Inc., a literary and software agency, and the publisher of the website Edge, the forum for leading scientists and thinkers to share their research with the general public."

Brockman's editorial skills contributed greatly to the success of this book. The essays that he presents are written in uncomplicated and focused prose. This makes them easy to understand -even for non-technical readers. The physicist Ernest Rutherford once said "If you can't explain a result in simple, nontechnical terms, then you really don't understand it."

In this post, I have tried to provide the basic elements of this controversy, and also to provide resources - so that readers can make an informed decision about what to believe. I invite your comments.

Will Liechtenstein Conference Deny the Existence of the Kong-ocost?


Today Liechtenstein one of the world's smallest countries, announced a Conference to examine whether The Kong-ocost (King Kong's 1933 rampage through New York City) ever really happened. The meeting is scheduled for February 2007. The announcement drew angry protests from some elderly New Yorkers.

Simon Plotsky, 96, voiced his objections. "We were there and saw with our own eyes what that monkey did to our city! It was Horrible! Horrible! We should never forget!" When Simon was asked where he lived in New York at the time of the incident, he could not remember. He also couldn't remember where he lives now.

CNN Reporter Mindy Lee spoke with Hans Frichter, the President (and also Mayor and Police Chief) of Liechtenstein about the meeting. Mr. Frichter said "We are a small country with limited income. Postage stamp sales to collectors have dropped off sharply in the past 10 years because of e-mails and the internet. Iran brought in a bundle of tourist dollars with their Denial Conference. Why shouldn't we cash in as well?"

When Miss Lee pointed out that King Kong was just a movie, not a real event, Mr. Frichter commented "Well, that is yet to be determined. You should come to the Conference and find out. I can get you a good deal on a hotel! Breakfast is included!"

Reaction to the Conference from the monkey world has been positive. P Monkey faithful sidekick of LonelyGirl15 said "The media should pay more attention to primate issues. After all, we've been around a lot longer than you humans!" The Bronx Zoo's Monkey and Ape Coalition also voiced support for the Conference. Spokesman Bongo Bongo (a 10 year old orangutan) commented "It's time to stop blaming us for the decline of Western Civilization. It's been more than 100 years since Darwin's book came out. Get over it!"

Hotel bookings and airline reservations for the tiny country have risen sharply. Mr Frichter is hoping for a slow news week, to increase press coverage. Or as he put it, "If nobody gets blown up, then Cha-Ching!"
