Gymnastic Enzyme Acts Like Logic Gate

An enzyme named vinculin undergoes “drastic” conformational changes, reports William A. Weis in the July 29 issue of Nature.1  Vinculin, with over a thousand amino acid links, is important at membrane junctions for transporting materials in and out of the cell.  It helps cellular “glue” exit the membrane so that neighboring cells can adhere to […]

In the Last Days There Shall Be Scoffers

Current Biology this week contains two entries either attacking creationism or exalting Charles Darwin.1,2  Nigel Williams reports on the 100th birthday of Ernst Mayr (see 07/02/2004 headline), and his “tireless campaign against creationism”: Ernst Mayr, the renowned evolutionary biologist and champion of Darwin, celebrated his 100th birthday earlier this month by leading a scathing attack […]

Cell Technology Celebrated

Humans are just beginning to imitate the manufacturing techniques cells use all the time, right under our noses.  A book just came out about the subject, entitled Bionanotechnology: Lessons from Nature by David S. Goodsell.  It’s hard to tell if Christof M. Niemeyer was more impressed with the book or with the living machines themselves, […]

ID Book Survives Nature Relatively Unscathed

Considering the intemperate disdain intelligent design books usually receive from the major journals – when they are even noticed (see, for example, Nature’s review of a book by William Dembski in the 07/11/2002 headline) – a new ID book fared surprisingly well this week.  In Nature1 June 24, Douglas A. Vakoch (SETI Institute) reviewed the […]

NASA-Ames Gives Darwin Credit for Antenna Design Project

A press release from NASA-Ames Research Center claims, “NASA ‘Evolutionary’ Software Automatically Designs Antenna.”  Using artificial intelligence software, their approach converged on the best design.  The article explains: “The AI software examined millions of potential antenna designs before settling on a final one,” said project lead Jason Lohn, a scientist at NASA’s Ames Research Center, […]

Gene Regulation: When Nonsense Makes Perfect Sense

Nature June 31 reports on another use for “junk DNA.”  A portion of previously-considered “nonsense” genetic code, which does not produce a protein as does a gene, nevertheless has an important role: it regulates the expression of the neighboring gene.  This opens a whole new realm of function for portions of our genetic material that […]

Cell Requires Two Keys to Let Cargo Pass

For high-security environments, guards sometimes require two independent authentication methods.  Before humans came up with this trick, the cells in their bodies were already using it.  Itoh and Camilli explain in the May 13 issue of Nature:1 Our cells contain a series of distinct compartments that do different jobs and have different properties.  The membranes […]

Former “Junk DNA” Now Considered Essential

The term “junk DNA” seems to be fading with each new discovery.  Helen Pearson, reporting for Nature Science Update, leads with the line “‘Junk’ DNA reveals vital role: Inscrutable genetic sequences seem indispensable.”  They don’t know what it does yet, but the assumption is it must be important for evolution to hang onto it for […]

Science Bashes I.D.

The Intelligent Design movement took another lashing by the journal Science,1 in the form of three book reviews by Steve Olson, a Washington DC area science writer.  Olsen reviewed one pro-ID book, Darwin, Design and Public Education by John Angus Campbell and Stephen C. Meyer, and two anti-ID books, God, the Devil and Darwin by […]

SETI Researcher Analyzes Language Mathematically

Space.com had a story April 22 about Dr. Laurance Doyle, who studies non-human communication with information theory.  The article is mostly about his study of whale and dolphin signaling, but mentions how information theory is related to the intelligence of the communicating entities: Doyle’s team uses statistical tools from a field known as “information theory” […]

Fake Darwinism Created by Intelligent Design

Scientists have created enzymes with enhanced ability to select between left- and right-handed molecules, using an “evolutionary” process, claims Manfred Reetz in a Perspective article in PNAS:1 A fundamentally new approach to asymmetric catalysis in organic chemistry is described based on the in vitro evolution of enantioselective enzymes.  It comprises the appropriate combination of gene […]

Articles

The cover story of World Magazine for April 3 is a series of prophetic articles for the Year 2025, called “Darwin’s Meltdown: Intelligent Design scientists … ponder a future free from the dogma of evolution.”  Looking back on how and why Darwinism declined into the “dustbin of discarded ideologies”, four intelligent design leaders, Phillip E. […]

Privileged Planet Website Opens

A website featuring a new book by Guillermo Gonzalez and Jay Richards, The Privileged Planet, has opened.  The subtitle of the book is How Our Place in the Cosmos Is Designed for Discovery.  The authors take issue with pessimistic views, such as those of Steven Weinberg and Carl Sagan, that our planet is “pointless” or […]

Evolution Battle Heats Up in Ohio

CNN has reported that the Ohio school board voted 13-5 in favor of an optional set of lessons called “Critical Analysis of Evolution.”  The usual opponents are lining up on both sides; some scientific organizations are claiming it is a “religious effort cloaked as science,” but others consider it a victory for students and for […]

Anthropic Principle Won’t Go Away

The so-called “Anthropic Principle” is the observation that the universe, whether by accident or design, appears to have been fine-tuned for our existence.  Dating back decades, if not centuries, the idea has been alternately criticized and seriously pondered by the world’s greatest cosmologists.  During the 1990s the idea was ridiculed to the point that, if […]
