Big Pieces Missing in Darwins Theory, Says USC Scientist
September 27, 2004
A USC professor of gerontology has “explored a new way to look at aging that directly opposes principles set forth by Darwin in his theory of natural selection,” reports EurekAlert (Emphasis added in all quotes). Valter Longo’s theory of aging employs group selection instead of individual selection (see 05/31/2004 headline). He thinks that in […]
Does Psychology Find Anything New Under the Skull?
September 25, 2004
Two recent psychological reports seem to either state the obvious or underscore teachings of old-time religion. Coping: EurekAlert tells about a University of Washington study that concluded, “Americans had strong need for spiritual support following 9/11 attacks.” Strangely, Christians and Jews, who believed in forgiveness, seemed to do better than Muslims who believed in retaliation. […]
Clean-Air Laws and Tree-Planting Cause Increased Air Pollution?
September 24, 2004
A major source of volatile organic compounds (VOCs), precursors of ozone pollution, is tree leaves, says a report in EurekAlert. Surprisingly, the increase in trees due to abandoned farms has worsened the pollution. Industry-caused nitrogen-oxygen (NOx) compounds also lead to ozone, and it is not clear how these sources interact. Nevertheless, it appears that reductions […]
Update: Intelligent Design Paper
September 24, 2004
The controversy over Stephen Meyer’s intelligent design paper (see 09/16/2004 headline) continues. Science printed a brief but dismissive news item claiming its publication was a mistake, but journal editor Rick Sternberg has answered the charges on his personal website. Meyer has responded to criticisms leveled by Richard Monastersky in the Chronicle of Education. The Discovery […]
Name-Calling at the Human Evolution Meeting
September 23, 2004
As predicted earlier this month (see 09/03/2004 commentary), Lucy’s lovers were not going to take her demotion lying down. Proponents of Orrorin claim their 6 million year old rival walked upright millions of years before the 2-4 million year old australopithecines, and even had a gait more human-like than Lucy. To Ann Gibbons, reporting in […]
Cell Exhibits Robust Engineering Design
September 22, 2004
Cells are so good at robustness against perturbations and uncertainty, engineers could well learn from their design principles.
Can Naturalism Design Anything?
September 22, 2004
Philip Ball in the Sept. 23 issue of Nature1 gave a title to a news feature that might catch a reader off guard and think he is allowing the Intelligent Design Movement to have a voice in a scientific debate: “Enzymes: By chance, or by design?” Upon further reading, however, it is clear the debate […]
New Treatment for Hyperactivity: Nature Walks
September 21, 2004
Hiking in the woods seems to alleviate ADHD, say two researchers from University of Illinois, in two studies mentioned briefly in Science News.1 The article begins, “Does spending more playtime amid greenery improve behavior in children with attention-deficit hyperactivity disorder?” (emphasis added). Apparently, yes. The setting, not just the activity, is part of the equation, […]
Introducing: The Spinach Cell Phone
September 21, 2004
The next spinach sandwich you hear about may not be an item at the health food bar but an electronic device powered by the sun. According to an MIT press release, chloroplasts from spinach leaves have been successfully sandwiched into a solid-state electronic photocell that could be used before long to power cell phones and […]
Scientists Try to Read Neandertal Minds
September 21, 2004
If dead men tell no tales, living ones certainly do. Most of us have trouble reading one another’s minds when staring face to face, but some paleoanthropologists, with nothing but skeletons and a few stone tools and burial sites to look at, have no hesitation in reading the Neandertal mind. Bruce Bower writes in Science […]
Termites: If You Cant Lick Em, Mimic Em
September 21, 2004
Termites, despite their bad rap, have something to teach human homebuilders. Their mounds are self-sufficient, air-conditioned, environmentally friendly and cheap to run, according to a story in EurekAlert. “The mounds incorporate a complicated network of tunnels and air conduits designed to channel air flow for the control of internal air quality, temperature and moisture levels.” […]
Arrow Worms Miss the Mark in Darwins Tree
September 17, 2004
Nature this week1 claims that “The origins of the arrow worms have long been obscure, but molecular studies are finally bringing the true evolutionary position of these beautiful marine predators into sharper focus.” (Emphasis added in all quotes.) Arrow worms, or Chaetognatha, are “strikingly beautiful marine animals.” writes Maximilian J. Telford. “Their transparent, slender bodies […]
Secrets of the Spliceosome Revealed
September 17, 2004
A husband and wife team from Hebrew University has revealed the structure of the spliceosome, one of the most complex molecular machines in the cell (see 09/12/2002 headline), in more detail than ever before, says EurekAlert. The spliceosome is responsible for cutting out the introns in messenger RNA after it has transcribed DNA, and also […]
Plants Use Quantum Mechanics to Harvest Light
September 16, 2004
In a News and Views item in Nature Sept. 16,1 Graham R. Fleming (UC Berkeley) and Gregory R. Scholes (U Toronto) explain how the light-harvesting centers of plant photosynthetic organs take advantage of quantum mechanics to focus energy on their reaction centers. Their illustration shows a chromophore diagram from a photosynthetic bacterium. Understanding energy transfer […]
Discovery of Transfer RNA Recounted
September 16, 2004
In the Sept. 16 issue of Nature,1 Mahlon Hoagland recounts how he did the key experiment in 1957 that proved DNA used “soluble RNA” intermediates, later named transfer RNA (tRNA), on the way to protein synthesis in the ribosome, only to find that Francis Crick had predicted the existence of such intermediates. By this time […]

David Coppedge, B.S. Education, B.S. Physics, founded Creation-Evolution Headlines in late 2000 as a way to share science news he was encountering at NASA. It has grown into a highly-trusted source of news and commentary critical of the pro-Darwin consensus, providing analysis of breaking news of interest to creationists and evolutionists, without the Darwin spin. He has authored over 7,000 entries at CEH since its inception.
