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.
Spin or Sin
November 1, 2011
You are bureau chief for a science news organization. Your job is to convince the public that science is right, and their doubts are wrong. You believe in reason and evidence, but you are frustrated that large segments of the population doubt the scientific consensus on certain hot-topic issues. The way to reach them, you say, is by coaxing people they already respect to convey the message, and use graphics to present the evidence. Sound reasonable?
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.
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.
NCSE Takes on Creation Geologists
October 23, 2011
The science of geology operates in parallel universes. There are the mainstream, secular geologists in the Geological Society of America who have complete hegemony in the secular universities, the mainline journals and the secular press. Then there are the creation geologists, who publish in their own journals; these hardly enter the awareness of the other geologists. Once in a while, though, like disturbances in the Force, emanations from the creation universe into the secular universe are felt. The National Center for Science Education has become so alarmed at these emanations that they have warned secular geologists to (1) pay them no attention, and (2) pay attention.
Can Biomimetics Shed Light on Evolution?
October 17, 2011
Biomimetics is part science and part engineering. The scientific part is to observe and understand the structure and function of a living thing. The engineering part is to apply that science into useful products. Science news articles today are claiming that a biomimetic flying machine modeled on insects is shedding light on evolution. Such a claim deserves some scrutiny.
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.
September 26, 2011
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.
Evolution Fits Any Data
September 23, 2011
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:
Stretching Credibility in Evolutionary Stories
September 20, 2011
Improbable events happening numerous times; selective extinctions; voodoo phylogenetics – at what point do evolutionary explanations exceed the threshold of credibility a trusting public grants to the gurus of the culture, scientists?
