The Origin of Specious Ideas: Did Darwin Explain Speciation?
April 29, 2005
Even though Darwin’s best seller was titled On the Origin of Species by Natural Selection, Albert and Schluter in Current Biology1 claim his title was deceptive: “Darwin’s book is about adaptation and the origin of varieties and has surprisingly little to say about selection and ‘the origin of species – that mystery of mysteries’.” Is […]
Evolutionary Psychology Wrong in Almost Every Detail
April 28, 2005
Seems like Darwinism can’t get anything right about the human psyche. Sharon Begley, writing in the Wall Street Journal, discussed David J. Buller’s new book, Adapting Minds (MIT Press, 2005), and found it “the most persuasive critique of evo psych I have encountered.” Buller details why evolutionary psychology, despite its bravado, fails to explain rape, […]
Extinct Woodpecker Found in Arkansas
April 28, 2005
One of the world’s largest woodpeckers, the ivory-billed woodpecker, thought for over 50 years to be extinct, has been spotted alive in the remote woods of Arkansas. See National Geographic News, New Scientist, and MSNBC for details. Update 07/21/2005: The good news may be premature. News@Nature says that some experts believe the observers were mistaken, […]
Nature Alerts Researchers to Threat of Intelligent Design Movement
April 27, 2005
It can’t be ignored anymore, reported Nature in two articles this week. Geoff Brumfiel1 asked academic researchers, “Who has designs on your students’ minds?” He reported on the rise of IDEA Clubs (Intelligent Design and Evolution Awareness, such as the first one at UC San Diego), highlighting the story of Salvador Cordova’s prospering IDEA club […]
Genes Must Be Expressed in the Right Order
April 26, 2005
A team of scientists in Switzerland made neural cells switch on a transcription factor earlier during the embryo’s development. The result? Axons (long branches of nerve cells) refused to grow to the spinal cord and to the peripheral target. To the mice, this meant they couldn’t feel things on the skin due to stunted nerves. […]
Titans Atmosphere Is a Hydrocarbon Factory
April 25, 2005
A press release from Jet Propulsion Laboratory announced the discovery of complex hydrocarbons in Titan’s atmosphere. Some molecules have up to seven carbon atoms. The discoveries came from the recent flyby on April 16, the closest yet, at just 638 miles above the surface. Swooping into the upper layers of the atmosphere, the spacecraft came […]
Hubble Telescope Celebrates 15th Birthday with Stunning Images
April 25, 2005
Fifteen years old this month, the Hubble Space Telescope showed off new images of the Whirlpool Galaxy and Eagle Nebula (see ESA press release). Engineers at JPL who built the WFPC-2 (Wide Field and Planetary Camera), the camera that took most of those famous images that adorn our walls and calendars, took great satisfaction today […]
Bacterial Hydrogen Fuel Cell May Yield Cleaner World
April 24, 2005
Scientists at Penn State are working on a new, improved fuel cell. Its secret? Bacteria that can be coaxed with a little electricity to produce “four times as much hydrogen directly out of biomass than can be generated typically by fermentation alone.” Will you someday be able to harness hydrogen from organic waste to drive […]
Giant Carnivorous Amphibians Found in African Fossil Deposit
April 23, 2005
Meat-eating amphibians shaped like crocodiles? Be glad you didn’t live in West Africa 250 million years ago, say scientists at McGill University. Two species were described, one with large and small fang-like teeth, and another with curved horns on the back of its head. The fossils didn’t come with dates on them, and since amphibian […]
In the Beginning, Hydrogen: Was It Miller Time?
April 22, 2005
A press release from University of Colorado says that the spark-discharge experiments of Stanley Miller in the 1950s (see 05/02/2003 entry) might be relevant again. Why? Researchers used new models to estimate the amount of hydrogen in the early earth’s atmosphere, and came up with numbers 100 times higher than before. If hydrogen did not […]
Evolutionists Plan Secret Weapon for Kansas Debate
April 21, 2005
Pro-evolution scientists have changed their mind and decided to join the hearings about the Kansas science standards, but haven’t released a list of witnesses. Those in favor of the new standards, which call for critical thinking about evolution, have published a complete list. On March 31, Geoff Brumfiel in Nature1 reported, “Biologists snub […]
How to Get Asteroid Dust Ponds in Mere Millennia
April 19, 2005
A team of U. of Colorado and MIT scientists modeled the formation of the smooth dust ponds found in some of the craters on the asteroid Eros by the NEAR spacecraft (see 02/13/2001 entry). They calculated that micrometeoroid settling from impacts was too slow a process, and instead ran experiments with electrostatic levitation of fine […]
Butterflies Really Know How to Fly
April 18, 2005
The path of a butterfly may appear haphazard to us, but there is a method to the fluttering. A UK team of scientists put transponders on butterflies and monitored their flight paths. They found that the looping paths appear to help with orientation and food detection. The rest of the time, they flew straight at […]
Temple Mount Debris Yields Artifacts from Solomons Temple
April 17, 2005
Israelis were shocked and outraged when Palestinians undertook an illegal construction project in 1999 on the Temple Mount, and threw the debris into the Kidron Valley outside Jerusalem, but there was little they could do about it. Though this “archaeological disaster” caused irreparable damage to the site, the holiest place for the Jews, some Israelis […]
Dinosaur Fossilized in the Act of Laying Eggs
April 15, 2005
Two eggs, with shell material still attached, were found inside the oviducts of a theropod dinosaur, a Chinese team reported in Science.1 This first-time discovery of intact eggs in the body of the female “suggests that theropod dinosaurs had two functional oviducts (like crocodiles) but that each oviduct produced only one egg at a time […]
