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, […]

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 Can’t 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 Darwin’s 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 […]

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 […]

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 […]

Peering Into Paley’s Black Box: The Gears of the Biological Clock
September 15, 2004
William Paley’s famous “watchmaker argument” for the existence of a Designer, though intuitively logical to many, has been criticized by naturalists on the grounds that one cannot compare mechanical devices to biological ones.  Biological “contrivances” might operate on totally different principles than mechanical ones made by humans we know.     Michael Behe’s 1996 book […]

Take Out the Garbage?  No– Feed the Worms
September 14, 2004
Every kitchen needs one, says National Geographic News: a popular new device that turns garbage into fertilizer.  What is it?  A new high-tech electronic machine?  No, something more ancient: a worm bin.  Modern homes are finding old benefits in vermiculture, the art of composting garbage into plant food via worms and bacteria.  A small bin […]

Salamander Genes Give Darwinists a Wake-Up Call
September 13, 2004
A press release from UC Berkeley says that the evolutionary family tree of salamanders, once thought secure, has been turned topsy-turvy by a study of the genes.  The opening paragraph is reminiscent of an irritating alarm clock going off in a comfy bedroom: Biologists take for granted that the limbs and branches of the tree […]

Is the Evolution of Bacterial Resistance a Just-So Story?
September 12, 2004
Evolutionists frequently point to the emergence of bacterial resistance to antibiotics as an example of Darwinian evolution occurring right under our noses.  Bruce R. Levin of Emory University, writing in the Sept. 10 issue of Science,1 is not so sure about that.  He points out that cells might just have a built-in mechanism to shut […]

Solar Particles Survive Genesis Crash
September 10, 2004
Scientists are relieved that they have been able to recover enough pieces from the crashed Genesis spacecraft to pursue the science objectives.  JPL Director Charles Elachi said they have snatched victory from the jaws of defeat and are bouncing back from a hard landing.  The highest-priority science goals may still be attainable, at least partially, […]
