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.
Man, Mammals, and Ice Ages
November 7, 2011
What do scientists really know about early man and the creatures in his habitat? Some clues can be found by following science news in a historical fashion: that is, to look for reversals of previously-held opinions, surprises in fossils, and other evidences that scientists are not really making progress in their theories, despite the common […]
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.
SETI at Night
November 4, 2011
For 50 years, searchers for extra terrestrial intelligence (SETI) have thought that radio waves would provide the best signals, being able to traverse at the speed of light with little scattering. Now, two physicists suggest another way: looking for the lights of their cities at night.
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?
It Emerged from Warm Mud
October 31, 2011
How would you feel if evolutionists told you that you came from mud? It’s probably not any worse than other notions they’ve been telling mankind for years: we all came from slime, primordial soup, volcanoes, or were seeded here by space aliens. How these notions find their way into science is an interesting question.
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.
Aliens Among Us
October 26, 2011
Some SETI researchers are looking for intelligent design on Earth – by aliens! Paul Davies has written seriously about the possibility of “alien bioengineering” that could be detected in DNA. NASA’s tax-supported Astrobiology Institute gave the idea good press, apparently unaware that most SETI researchers and astrobiologists vociferously reject the theory of intelligent design.
The Blind Men and the Ape Man
October 25, 2011
“We have all seen the canonical parade of apes, each one becoming more human. We know that, as a depiction of evolution, this line-up is tosh. Yet we cling to it. Ideas of what human evolution ought to have been like still colour our debates.” So said Henry Gee, editor of Nature. Are other icons coloring scientists’ views of human origins? How close are they to describing scientifically where we come from?
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.
Evolutionary Guru Deceives Himself
October 12, 2011
Maybe you’ve had this experience: you’re in class, taking notes, and after a long lecture, the teacher realizes something wrong, and announces, “Forget everything I just said.” Frustrating, isn’t it? That’s what a recent article on evolution did. An evolutionary psychologist explained the origin of lying, then admitted he is self-deceived.
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.
