Deep Life Is Right at Home in Total Darkness
October 10, 2008
It seems every year scientists find organisms thriving in environments thought too inhospitable for life. A new word was coined for these organisms: extremophiles – lovers of the extreme. Two recent discoveries push the envelope of extreme environments almost to the deep limit. Pressurized fish: The bottoms of the deep ocean trenches of the Pacific […]
A Turtle Missing Link: Are We Missing Something?
October 9, 2008
Everyone knows the iconic drawing of the parade of human evolution (see 09/23/2008 commentary); now, its turtle counterpart is making the rounds. An article on New Scientist shows the march of progress from lizard to turtle. The title says, “Fossil reveals how the turtle got its shell.” Something is missing from the article, though: a […]
Its Fun Seeing Evolution Falsified
October 8, 2008
“Mysterious Snippets Of DNA Withstand Eons Of Evolution” is the strange title of an article on Science Daily. Gill Bejerano and Cory McLean from Stanford are wondering why large non-coding sections of DNA are very similar, or “ultraconserved,” from mice to man (see 08/18/2007). Evolutionary theory would expect that non-functional genetic material would mutate more […]
Are We Getting Biased Science?
October 7, 2008
Much more scientific research is being done than ever gets reported, say three researchers in a story reported by Science Daily. High-impact journals tend to report selectively from a large field of medical and laboratory research. As a result, “only a small proportion of all research results are eventually chosen for publication, and these results […]
Walk the Ediacara Two-Step
October 6, 2008
Controversy is swirling around claims that footprints have been found in rock 30 million years earlier than the Cambrian explosion. The press release on Ohio State shows a picture of parallel rows of dots that a team from Ohio State claims look like footprints of a worm-like or millipede-like animal. The rocks are said to […]
Dark Energy May Be an Optical Illusion
October 5, 2008
Cosmologists can get rid of the burden of their worst imponderable substance, dark energy, if they are willing to jettison the Copernican Principle. Science Daily reported thinking by a team of Oxford physicists who make the apparent acceleration of the universe an artifact of our viewing position. When distant galaxies are viewed without the assumption […]
Living Better Bioelectrically
October 4, 2008
Electric eels are inspiring a new generation of fuel cells. Science Daily reported that a remarkable fusion of engineering and biology may lead to tiny electronic devices that run on biology’s own energy currency, ATP. “Engineers long have known that great ideas can be lifted from Mother Nature, but a new paper by researchers at […]
Bangin Around to Get Something New Under the Sun
October 3, 2008
You’ve heard of the Big Bang, and the Cambrian Explosion. Now, to get the solar system started, astronomers have added a Little Bang to move things along in the naturalistic path from nothing to everything. Science Daily, Space.com and PhysOrg all reprinted a press release from the Carnegie Institution claiming that a nearby supernova led […]
Reducing Human Behavior to Natural Laws
October 2, 2008
Can human behavior be reduced to natural laws that science can study in a morally neutral way? Darwin sought to incorporate all aspects of the living world, including behavior, in natural laws that were amenable to scientific explanation. Evolutionary biologists and neuroscientists continue in that tradition today. Consider two recent examples in the literature that […]
Brain Candy as Tiger Milk
October 1, 2008
Observation: the human brain appears able to use lactate as fuel instead of glucose during strenuous exercise (see Science Daily). Deduction: From an evolutionary perspective, the result of this study is a no-brainer. Imagine what could have or did happen to all of the organisms that lost their wits along with their glucose when running […]
How the Evolution Story Became Like Jellyfish
September 30, 2008
“How the [blank] got its [blank]” is the template for story titles imitating Rudyard Kipling’s Just-So Stories: i.e., How the Camel Got His Hump and How the Leopard Got His Spots. Kipling wrote these as silly stories to entertain children, not to be taken seriously by scientists. Knowing that creationists often criticize Darwinian explanations as […]
Did This Dino Have Bird Breath?
September 29, 2008
Birds are the only vertebrates with a unique one-way, flow-through breathing system that includes hollow bones. Their unique respiratory system is part of the set of features that allows flying with its need for rapid metabolism. Science news outlets are clucking wildly about another putative missing link between dinosaurs and birds: “Meat-eating dinosaur from Argentina […]
Darwinists Root for Obama
September 28, 2008
Ministers in churches are not allowed to promote political candidates, even though they do not take government money.1 Scientists, who often do take federal money in the form of grants, openly take positions on the presidential candidates they feel will further their interests. Is this proper? Both Nature and Science this week did […]
Fastest Squirt Gun in the Fungi
September 26, 2008
A paper on PLoS One described the highest-speed flights in all nature: the spore discharge mechanisms in certain fungi. A dozen scientists in Ohio worked to capture the action on ultra-high-speed cameras. It took 250,000 frames per second to reveal how fast the projectiles accelerate. The answer: from 20,000 to 180,000 g (where g = […]
Trees Communicate with Aspirin
September 25, 2008
Plants communicate with each other through chemical signals. Scientists found a form of aspirin that works as a distress call.
