Amazing Bird Tricks
October 27, 2011
“Angry Birds” are perhaps the best known species among electronic bird-watchers these days, but we should never forget that real birds are amazing creatures. Incredibly diverse (think ostrich to hummingbird to penguin), they continue to fascinate scientists and laymen. Here are some recent science stories about our feathered friends.
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.
Enjoy Your Body Gifts
September 29, 2011
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.

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.
It’s Still a Rare Earth
September 25, 2011
Now that hundreds of extrasolar planets are known, how do they compare to ours? The Kepler spacecraft has found a varied assortment of all sizes and distances away from their parent stars. Only a few reside in their star’s habitable zones. But that’s only the first of many requirements for life. Two recent studies indicate that Earth remains a rare bird in the celestial aviary.
Venus Flytrap De-Darwinized
September 12, 2011
Darwin had a fascination for the Venus flytrap, but is it appropriate to conjure up his ghost when talking about it? The carnivorous plant still defies evolutionary explanations, especially now, when a recent paper drew attention to more amazing design features from macro to micro. For some reason, writers still feel a compulsion to mention Darwin’s name when talking about a plant that defies his evolutionary ideas.
Are Biological Clocks Like Paley’s Watch?
September 9, 2011
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?
Adventures in Biomimetics
September 2, 2011
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
August 30, 2011
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”.
Lucky in the Sky with Diamonds
August 25, 2011
There are treasures all around us we do not perceive. Sometimes we speak figuratively about sparkling gems that are, if we realized it, literally real, right there under our noses. Children sing, “Twinkle, twinkle little star, how I wonder what you are, up above the world so high, like a diamond in the sky” without knowing that there really are diamond stars up there, with diamond planets, so magnificent and huge they are unfathomable in value. These are actual discoveries that have been announced by scientists this week.
Hi-Tech Pharmaceutical Plants Are Green
August 19, 2011
In environmental lingo, what could be greener than a tree? And what is more despised by many environmentalists than chemical companies, especially the pharmaceutical and pesticide industries? Maybe we should take a tip from plants. They are not just environmentally friendly, they produce a myriad of complex compounds that are slowly finding their way into healthful products—and evolutionists have no idea how they do it.
Your Rotary Engines Are Arranged in Factories
August 17, 2011
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.
Unique Mammal Senses
July 30, 2011
The ability to sense the environment is vital to all living things, and is a key characteristic that separates life from non-life. The senses are not limited to the five we learn as children – sight, hearing, touch, taste, and smell. In the animal kingdom there are more. Some of them repurpose existing organs; some detect other information from the world not detectable with the normal sense organs. In mammals, two very different animals – bats and dolphins – have expanded our understanding of sensation.
