Cell Chaperones Keep Proteins Properly Folded
August 2, 2011
Imagine linking together a chain of 300 plastic shapes, some with magnets at various places. Then let it go and see if you could get it to fold spontaneously into a teapot. This is the challenge that cells face every minute: folding long chains of amino acids (polypeptides) into molecular machines and structures for the cell’s numerous tasks required for life. DNA in the nucleus codes for these polypeptides. They are assembled in ribosomes in single-file order. How do they end up in complex folded shapes? Some polypeptides will spontaneously collapse into their native folds, like the magnetic chain in our analogy. Others, however, need help. Fortunately, the cell provides an army of assistants, called chaperones, to monitor, coax, and repair unfolded proteins, to achieve “proteostasis” – a stable, working set of proteins. That army is so well-organized and complex, scientists continue to try to figure out how it performs so well in the field.
Clue or Clueless on Plant Evolution
August 1, 2011
An article on The Scientist promised to provide “clues to plant evolution,” but the data seemed like clues to something else – namely, design. The article was about how plant proteins interact with one another – the “interactome” (another word to add to genome and proteome). Did the work actually fulfill evolutionary predictions? Even if they claim it did, did it really?
Earth Uniqueness Up; SETI Down
July 29, 2011
Our earth seems special – maybe because it is. Some astronomers are seriously considering that life might be rare or unique on our rare (or unique) planet. If so, hopes for finding sentient aliens on the celestial radio dial drop accordingly. The 50th anniversary of the first SETI search came, unfortunately for search enthusiasts, came at a time when funding is harder to get.
Archaeopteryx Reclassification Raises Fear of Creationists
July 28, 2011
Archaeopteryx isn’t the first bird. At least, not today. It may be reclassified again, but Xing Xu, the man who brought a panoply of “feathered dinosaurs” to the world’s attention, has announced another Chinese fossil that led him to shuffle the bird evolution tree around, putting Archaeopteryx, an “icon of evolution” since its discovery in1861, onto a branch that includes dinosaur terrors like Deinonychus. At least, today. The backstory behind the shuffling of family trees, an upset that raises questions about everything evolutionists that they knew about the evolution of birds, is political, not scientific. Evolutionists are worried about how creationists are going to “spin” the news.
Weird Evolution Tales
July 27, 2011
Evolutionary theory leads to some fantastic tales. Since evolution is often presumed to be a fact that explains everything in biology, and is itself not subject to testing or doubt, everything in biology must be viewed through an evolutionary lens. This hard-core stance on evolution often leads to assertions and explanations that appear contrived, if not preposterous, to Darwin doubters. Here are some recent examples of weird evolution stories that made it past the logic inspectors simply because evolution is unquestioned.
Butterfly Swarm Buries Darwin
July 25, 2011
Billions of butterflies, flashing their gossamer wings with brilliant colors, have swarmed over Darwin, leaving him unable to breathe. Figuratively, that is. Illustra Media’s new documentary Metamorphosis, just released on Blu-Ray last week, leaves little room for Darwin’s theory, while making a powerful case for intelligent design. The film is already being hailed as a masterpiece.
Norway Killer Cultural Christian, Practical Darwinian
July 24, 2011
Initial news reports about mass murderer Anders Breivik, who slew over 90 civilians in his home country on July 23, described him as a “right-wing fundamentalist Christian.” Now that his 1500-page manifesto has been published, it is clear that any associations with Christianity were cultural and political, not personal. His prime motivation was to halt the Islamization of “Christian” Europe brought on by political correctness and multiculturalism. A review of his writings show him closer to secular science and the social Darwinists than to the teachings of Jesus Christ.
Texas Press Perpetuates ID Myths
July 22, 2011
Some reporters refuse to listen. Advocates of intelligent design (ID) have clarified their definitions, their evidences, and their goals for years now, with numerous books, essays, web articles, papers and lectures, but the secular mainstream press continues to misrepresent their positions, and divert discussion from the issues to red herrings. A vote by the Texas School Board concerning supplementary materials to match science standards offered the latest example. The Associated Press story is filled with talking points and generalities; the Discovery Institute response is detailed and to the point, citing scientific journal references for support. Will intelligent design ever get a fair hearing in the mainstream media?
OOLs for Evolution
July 21, 2011
Soviet communists may or may not have needed Rules for Revolution, but Darwinists, without doubt, need OOLs for Evolution: i.e., origin-of-life scenarios. Obviously, Darwinian evolution won’t get past square one without a self-replicating system complex enough to call “life” in place. Whether or not a given evolutionist is a Marxist materialist or a theistic Darwinist, OOL is a key link in the naturalistic dream of an unbroken chain of natural causes from big bang to man. It’s proving a tough link to find.
Fossil Finds Feed Facile Fables
July 20, 2011
Remarkable fossils continue to come to science’s attention, yielding clues about past ecological conditions. Once in awhile, whole fossil specimens – even graveyards of many organisms – are uncovered, but most fossils are mere fragments. Placing fossils into interpretive stories requires knowledge of other fossils and comparisons with living species. Even then, the history of life is not directly observable. Fossils, being silent, can only show their current state; the lack of access to the past, combined with ignorance of all the clues, leaves room for alternative interpretations. Evolutionists, in their desire to fit fossils into a preconceived story, sometimes go far beyond what the actual fossil evidence is capable of saying – and some of their explanations border on the miraculous.
Evolutionary Psychology Is So 1980
July 19, 2011
Evolutionary psychology, popular in the 1980s, has been criticized by some evolutionists as flawed in its basic assumptions. In practice, evo-psych explanations were often so speculative, they amounted to little more than “evolutionary storytelling,” according to an article on PhysOrg. Popular articles still arise from time to time telling us that our minds evolved to cope with hunting and gathering, not the stresses of modern city life (see for instance, “Evolutionize Your Life” from the 07/14/2011 entry). A team now admits that the foundations of evolutionary psychology were always questionable. But never fear, they say: new evo psych is coming!
Body Language Says Design
July 17, 2011
Your body is speaking to scientists. Some of them hear it saying evolution. Others think it says intelligent design. What characteristics would each side expect? Most people intuitively know design when they see it. Here are three recent scientific papers that may help interpret body language.
Cell Operations Amaze, Inspire
July 16, 2011
A student's view of a cell under a light microscope is misleading. It reveals only a tiny fraction of what is really going on. Within that package of life, invisible to the student's gaze, complex machines work together in cellular factories. Signals pass back and forth in complex networks. Libraries of code are transcribed and […]
Evolutionary Contradiction As Mental Illness
July 14, 2011
In their efforts to get their theory accepted, have some evolutionists crossed the line into irrationality? It is mentally sound to espouse well-argued points of view, even if controversial. What is marginal is arguing self-contradictory beliefs. Let the reader judge whether any of these ideas from evolutionists make sense.
Plant Patterns Prolong Perplexity
July 11, 2011
Plants perform a wonder that has attracted the admiration of scholars from ancient Egypt, Greece and Rome to modern times: the ability to reproduce mathematically perfect patterns. This ability, called phyllotaxis, can be described mathematically with the Fibonacci Series and the Golden Angle. The beautiful spirals in sunflowers, artichokes, cacti, dandelion heads and other plants continue to fascinate children and adults today, but those are not the only examples. Leaves on a stem can emerge in phyllotactic patterns like a spiral staircase, and depending on the environment, plants can switch patterns at different stages in development. Scientists have learned a lot about the players in the phyllotaxis game, but still do not understand the script. The details of how genes and proteins produce the patterns remain elusive.
