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.

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.

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in molecular biology, population genetics, biogeography, paleontology have left the Victorian concepts of evolution outdated and antiquated, they would say.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.

Methuselah Seed Now a Tree

December 4, 2011

The world’s oldest viable seed is now a tree 8 feet tall. The Methuselah palm, discovered in the 1960s as a seed at the Judean fortress of Masada, sprouted in 2005 under controlled conditions. It is the oldest seed verified by radiocarbon dating to be 2,000 years old – from the time the Romans were besieging the mountain fortress built by Herod the Great.

Evolutionists Flaunt Falsifying Fossils

November 26, 2011

If Darwin’s theory were true, would you expect to find fossils that haven’t changed for a billion years? Would you expect that kind of stasis for organisms that lived in vastly different conditions than today? Would you expect, furthermore, to find an explosion of diverse forms of life suddenly, without ancestors? Rather than mourn their fate, evolutionists flaunt these falsifying fossils as trophies of their theory.

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.

Follow the Stem Cell Money

A major clinical trial using embryonic stem cells was suddenly halted this week. Meanwhile, trials with adult stem cells are steamrolling ahead. Why the difference?

Whale Fossils: Challenge or Support for Evolution?

November 14, 2011

When most fossils consist of small shelly creatures, finding a whale is indeed big news. Two whale fossil discoveries on opposite sides of the world are spectacular and puzzling. Do they support the theory that whales evolved from land mammals?

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.

Engineers Tip Hat to Nature

November 6, 2011

It’s conventional in blogging to give an HT (hat tip) to a friend who makes you aware of a cool item. Engineers are giving hat tips to plants and animals as they seek for amazing new products that do wonderful things, just like the ones in nature.

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.

Vitamin C Loss Is Not Evolution’s Gain

November 2, 2011

Evolution predicts gain of function; genetic entropy predicts loss of function. A gene that helps synthesize Vitamin C provides a test between the two views.
