Synthetic Evolution Is it Really Intelligent Design?
March 18, 2010
Some Cambridge scientists engineered a four-character genetic code and made some proteins with it. They guided the process at every step, but claim that they “evolved” this code. Is that a fair use of language? This strange admixture of concepts is found in today’s issue of Nature.1 The confusion began right in the title: “Encoding […]
The Copernican Geological Revolution
March 17, 2010
The Copernican Revolution did not just affect astronomy and physics: it revolutionized geology.
Search for Intraterrestrial Life Scores Big
March 16, 2010
Single-celled organisms may be tiny, but what they lack in bulk they make up for in volume and importance. Scientists have been appreciating more than ever the ubiquitous presence of microbes on our planet and the roles they play to sustain the biosphere. PhysOrg reported that half of the world’s life may lie […]
Mars Discoveries Change Paradigms
March 15, 2010
Mars is under assault by an armada of orbiters gathering intell from the planet with photons and radar beams. What kind of information has been seized recently? Dry rivers: Remember the networks of river channels that were telltale signs of water? Remember the hope for life those images generated? Some of those riverbeds could have […]
Robotic Pothole Crew Keeps Your Genetic Highways in Good Repair
March 14, 2010
What a thought – a repair crew of molecular machines roaming the strands of your DNA, fixing errors 24 x 7. It happens. New techniques are showing the machines jumping from strand to strand like fleas, stopping at suspicious points, and fixing errors, reported Science Daily. Dr. Bennett Van Houten (U of Pittsburgh Cancer Institute) […]
Fruit Flies: From Darwin to Design
March 13, 2010
The fruit fly Drosophila melanogaster is an icon of evolution. Since the 1930s these poor little bugs have been mutated endlessly and watched for signs of Darwinian change. So far, though, only useless mutants, unable to survive in the wild, have been produced. Recently, scientists seem more enamored with their design. Two recent articles had […]
Man Will Never Fly (to the Stars)
March 13, 2010
It’s risky to say “never” in science. The Man Will Never Fly Society had a short life. However, an article on Space.com makes it seem a safe bet that, Star Trek notwithstanding, warp-speed flights to the stars are out of the question for humans. “Warp speed will kill you,” the article announced; why? Because interstellar […]
Whos In Control: Your Brain or You?
March 12, 2010
Do you have a self that controls your brain, or is thought a secretion of the brain, as Darwin claimed? Do you use your brain, or does your brain operate you? Who is in charge? These are deep philosophical questions with a long history, that some people prefer to avoid, as in the common joke: […]
Science Proves the Morally Obvious
March 11, 2010
When scientists find that virtue brings reward and vice bring trouble, are they doing a better job than preachers and parents? Hold that thought while reading some of the things scientists have been telling us lately about ourselves. “R-Rated Movies Increase Likelihood of Underage Children Trying Alcohol.” Thank Science Daily for that bit of advice […]
Divining Violent gods as Natural Cosmic Creators
March 10, 2010
Ancient stargazers imagined the violent actions of gods in the heavens giving rise to the stars, earth and man. Today’s secular astronomers engage in a similar kind of lore. While not naming their gods after mythical heroes, they describe them as forces of nature whose violent clashes give rise to order and design. Sometimes they […]
This Tree of Life Is Real
March 9, 2010
Imagine a tree that can provide both nutritious food and clean water. Moringa oleifera is such a tree. It grows in Africa and Asia and is being looked at as a life-giving plant that can reduce bacterial contamination of water by 90 to 99.99% by filtering water with its seeds. Science Daily has […]
What Good Is Natural Selection without Progress?
March 8, 2010
Three papers recently claim to have seen natural selection. None of them, however, identified a functional advantage that would have tied changes to novel benefits that could improve a species. Yeast: “New Type of Genetic Variation Could Strengthen Natural Selection,” trumpeted a headline in Science Daily. It was about a study of two varieties of […]
Life Crams Stuff on the Long Road
March 7, 2010
This quote from UC Berkeley wins Stupid Evolution Quote of the Week: In the long evolutionary road from bacteria to humans, a major milestone occurred some 1.5 billion years ago when microbes started building closets for all their stuff, storing DNA inside a nucleus, for example, or cramming all the energy machinery inside mitochondria. Any […]
Natural Wonders Can Be Useful
March 6, 2010
To find great ideas, look to nature. Many plants and animals are as useful as they are ornamental. They can show the way to solve problems of great interest to humans. Mussel power: Want an abrasion-resistant, highly-extensible coating? PhysOrg reported that mussels are providing inspiration to materials scientists. They build a byssus, or network of […]
Dinosaur Evolution Is Relative
March 5, 2010
The science news media are all reporting that the “oldest known dinosaur relative” has been found. The artist reconstructions of Asilisaurus kongwe, found in middle Triassic layers in Tanzania, make the creature look quite dinosaurian; at least it was dog-sized and walked on thick legs under its body like its famous brethren did. Its early […]
