Your Motor/Generators Are 100% Efficient

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

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

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

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.

Enjoy Your Body Gifts

When you eat right and exercise to do your body good, you may have little idea how much your body is giving back all the time. From recent scientific discoveries, here’s a look at a few mechanisms under our skin that not only keep us alive, but provide us with a shopping mall of good things.

Amazing Adaptations

All biologists agree – creationists and evolutionists alike – that organisms show remarkable adaptations to their environment. They differ only in their explanations for how they got that way. Here are some remarkable examples of adaptation that will challenge any theory of origins.

Evolution Fits Any Data

At first blush, it might seem a wonderful thing when many different kinds of evidence can be explained by one simple, elegant theory. Actually, though, too much confirmation can be a theory’s downfall. When a theory explains too much – even opposite things – it really explains nothing. For instance, everything in the universe can be explained by the phrase, “Stuff happens.” Such a theory is useless, even if true. That’s why any theory that explains too much should be looked at askance. Here are some recent observations offered in support of the theory of evolution:

Human Genome Individuality Adds New Questions

Mission accomplished: “The Human Genome Project” was in the bag by 2003. Now we understand how humans are genetically wired, right? Not so fast. Another human genome was just published, raising a whole new set of questions. The big issue is that we all have two genomes in one – one from each parent. Biologists knew this, of course, but for the first time, those two genomes were untangled from one another, and a lot of differences were found: two million, in fact. How do our two separate genomes behave toward each other? And if genomes differ this much, what does a concept like “the human genome” really mean?

Are Embryonic Stem Cells Obsolete?

Adult stem cells can apparently do everything embryonic stem cells can – and they are moving regenerative medicine forward faster, with more results. Since the use of human embryos for research is ethically repugnant to many people, what motivations remain to continue the practice? Here is a rapid-fire list of stem cell news this month:

Are Biological Clocks Like Paley’s Watch?

What is a clock made of? We think of springs, gears and moving parts made out of metal. But a clock could, in theory, be designed with almost any material. There are water clocks, sundials, and electromagnetic oscillators that all function to tell time. What difference does it make if the parts are made of liquids, laser beams, or plastic? What if a clock was made of biological material—would it be any less a device for keeping time? Would it surprise you that such clocks exist in your body and in every living thing?

A Tale of Two Falsifications of Evolution

In diatribes against creationists, evolutionists have long pointed to antibiotic-resistant bacteria as examples of evolution in action. Since antibiotics were unknown before the 1920s, debaters have taunted their creationist opponents with the claim that evolution is such an observable fact, we’re watching it happen right before our very eyes. The force of that argument has been undermined with a new discovery this week that pushes the “evolution” of such resistance way back before human civilization arrived. Another article is claiming that human brain chemistry existed way, way back, “long before animals, brains and even nerve cells existed.”

Adventures in Biomimetics

The imitation of nature in engineering has become one of the hottest trends in science. Almost every week, amazing technologies are being advanced the easy way – by observing how living things do it. We all stand to benefit from the design-based science of biomimetics. Here are a few recent examples.

Pascal to Your Health

Blaise Pascal joins Louis Pasteur among the ranks of creation scientists who have improved the safety and nutrition of our food. We all know about pasteurization, the process of eliminating germs by gentle heating, but have you heard of pascalization? It’s “a century-old food preservation technology, finding a new life amid 21st century concerns about food safety and nutrition,” reported Science Daily. The process “more than doubles the levels of certain healthful natural antioxidants in fruit.” Pascalization will give new meaning to the term “fresh squeezed”.

Your Rotary Engines Are Arranged in Factories

As if ATP synthase was not amazing enough, a team of scientists in Germany now tells us they are arranged in rows with other equipment to optimize performance. From electron micrographs of intact mitochondria, they were able to detect the rotary engines of ATP synthase and other parts of the respiratory chain. Their diagram in an open-source paper in PNAS looks for all the world like a factory.

Would Wood Evolve?

The woods. We call them by their primary substance: wood. But would wood evolve from plants lacking woody stems? Was there some evolutionary pressure to force plants to grow tall to reach the sun, so that lucky mutations found a way to produce lignin and the other building blocks of wood? What other mutations did the blind evolutionary algorithm have to find to organize the components into trunks for trees? Two discoveries, a fossil and a mechanism, offer evolutionists a way to enhance their woody story.
