Cells Optimize Their Tasks
December 28, 2011
The key to design in manufacturing is optimization – hitting the “sweet spot” between competing interests. It’s not always possible to have all the elements of a product be ideal. A laptop computer, for instance, can’t have an extra-large monitor and simultaneously have long battery life and compact design. A muscle car cannot be expected to have the best gas mileage. In the heyday of “faster, better, cheaper” spacecraft, engineers often joked, “pick any two.” In the same way, living cells have to optimize their operations. A couple of recent papers explore how they find that sweet spot.
Dino Expert Plays Chicken
December 28, 2011
Jack Horner, the dinosaur hunter who was science advisor to the Jurassic Park movies, wants to create a real dinosaur. He won’t use the movie method, trying to extract blood from Jurassic amber, because “DNA degrades too quickly,” he said. But he has a method he thinks will work: un-evolve a chicken back into its dinosaur ancestor.
Humans Evolved from Pigeons
December 26, 2011
Experiments with pigeons show that their intelligence matches or exceeds that of chimpanzees. If evolutionists can infer that chimpanzees are our closest living relatives based on intelligence, why wouldn’t it be just as logical to infer that humans evolved from birds? As some recent articles show, such a whimsical story does not exceed in silliness what some evolutionists actually do claim.
Naturalizing Miracles, or Miracle-izing Nature?
December 24, 2011
Certain scientists feel a need to explain all phenomena by means of natural processes, including reports of miracles. The word “natural,” however, is slippery, taking on a variety of meanings. Is scientific reasoning, for instance, natural? If so, it is not composed of atoms and forces acting according to “natural law.” Is it possible that the tables can be turned on the naturalizers, to rescue Christmas from materialist re-interpretation?
Human Variability Can Be Rapid
December 19, 2011
All living humans are interfertile – one species by definition. People from all parts of the globe can marry and have children, even though global travel is relatively recent in human history. Yet we know there is considerable variability between tribes and nationalities. Does this variability take millions of years? Does it lead to the origin of new human species? Recent evidence shows that variations can be rapid, both genetic and acquired, without reducing interfertility.
Philosophy on the Phringe
December 17, 2011
Some philosophy is just common sense. Some is abstruse, recondite, and technically challenging. But when employed against common sense, such as to support the belief that everything came from nothing, philosophy can get downright weird.
Hopping Fish and Other Darwin Mysteries
December 12, 2011
The chieftans of evolutionary theory insist that their doctrines have come a long way since Darwin. Discoveries in molecular biology, population genetics, biogeography, paleontology have left the Victorian concepts of evolution outdated and antiquated, they would say. Yet a look at the evolutionary literature shows otherwise. Simplistic just-so stories, Darwinian phrases like “survival of the fittest” and “missing link,” iconic fossils, and antiquated principles continue to be the rule, as the following articles illustrate.
Biomimetics for Your Christmas Wish List
December 8, 2011
Biomimetics (the imitation of nature) continues to promise cool gadgets and useful materials that will someday yield prized gifts under the tree. Some of them might even save your life.
Cambrian Predator Had Modern Eyes
December 7, 2011
An exquisite fossil alleged to be 515 million years old shows a compound eye so complex, it looks as good as any modern insect’s eye. The eye belonged to Anomalocaris, the fearsome predator of Cambrian seas, one of the key players in the Cambrian explosion – the sudden appearance of all the animal phyla in the earliest rock layers.
The Science of Atheism
December 6, 2011
Science news sites have recently included some unusual articles: reports about the science of atheism. What can scientists say about atheism without leaving the domain of science altogether?
Fungi Shed Light on Deep Biological Mysteries
November 20, 2011
Fungi are among the least studied and least understood organisms. Elevated from plants to their own kingdom in 1969, they are extremely diverse yet difficult to observe, since many species cannot be grown in the lab. The gaps in our knowledge of the fungi are being filled by new efforts to catalog them, but one of the most interesting findings may come from analysis of their genomes. A new study shows that introns (intragenic regions) are more dynamic than previously thought.
Phillip Johnson Re-Buries Darwin
November 13, 2011
Darwin may still rule from the grave, but Phillip Johnson has good reason to hope Darwin’s ghost will decay with the old evolutionist’s interred bones. A father of the intelligent design movement, Johnson wrote and spoke and influenced many with his focus on the linch pin of Darwinism, its insistence on undirected natural processes. It’s […]
Animal Plan: It Works Well
November 10, 2011
There were Greek and Roman naturalists who were intrigued by what they saw in the living world, but their observational tools were limited to their five senses. Modern science has expanded our senses far beyond the capabilities known just a century ago. We are privileged to live in an age of discovery that is revealing even more wonders beneath the surface of living things, wonders worth knowing about. Here are just a few.
Your Copper Pipes
November 8, 2011
Each of us is part metal. Our bodies contain iron, copper, zinc, magnesium, manganese, vanadium, molybdenum, selenium, and even nickel like the coins in our pockets or purses. Unlike the other common elements of life (carbon, oxygen, hydrogen, calcium, nitrogen, phosphorus), our metals are not synthesized and recycled, but must be imported and handled with care. Copper is a good example of a biological metal that performs multiple useful functions – that is, unless something goes wrong with the machinery handling it.
Preventing Aging Through Darwin-Free Science
November 3, 2011
Will new discoveries in biochemistry lead to longer lives? There are hopeful signs that aging can be delayed, if not prevented. Whether or not that happens in our lifetimes (causing new worries for Social Security), scientists are learning amazing things about how cells work that should give us more reason for Thanksgiving.
