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.
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in molecular biology, population genetics, biogeography, paleontology have left the Victorian concepts of evolution outdated and antiquated, they would say.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.
Follow the Stem Cell Money
November 15, 2011
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?
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.
Animal Magnetism and Other Wonders
October 30, 2011
What is it that so attracts us to animals? Is it animal magnetism? Some animals do have magnetic senses that can guide them across oceans. The more we learn about animals, the more we should admire their high-tech equipment. Here are some recent examples of amazing animals, some of them suitable for Halloween decorations.
Your Motor/Generators Are 100% Efficient
October 14, 2011
ATP synthase astounds again. The molecular machine that generates almost all the ATP (molecular “energy pellets”) for all life was examined by Japanese scientists for its thermodynamic efficiency. By applying and measuring load on the top part that synthesizes ATP, they were able to determine that one cannot do better at getting work out of a motor – a motor that is also a generator.
Biomimetics to the Rescue of Science
October 10, 2011
The booming field of biomimetics (imitating nature’s designs) is fascinating not only for the amazing products it promises, but for the fresh new opportunities it provides for science and engineering. From viruses to mammals, everything in the living world is now being seen in a new light: agents of innovation that humans can learn from. Here are just a few examples in recent news, arranged in order from large to small inspirational creatures.
Mighty Mitochondria Conduct Energy Exquisitely
October 7, 2011
None of us could live without mitochondria. These are the power centers ubiquitous in eukaryotic cells. They contain molecular machines in factories whose jobs are to generate and conduct electrical currents. The currents run turbines that packetize the energy in molecules of ATP, which are then used by most processes in the cell. New discoveries continue to fascinate scientists with how mitochondria work. Some scientists use their energy to find ways Darwinian evolution could build the machinery of life.
Lucky LUCA Was Already Complex
October 5, 2011
Simple to complex: that’s been the essence of evolutionary theory ever since Charles Darwin imagined some organic molecules coming together in a warm little pond eons ago. Whatever simple life form emerged from his pond started his evolutionary process that led to the human brain. But what if the “last universal common ancestor” was already highly complex? What if bacteria and archaea are “devolved” remnants of a more complex ancestor? That’s exactly what a new study is claiming.
