Astronomy Grab Bag
December 29, 2012
For year's end, here's a clean-out of astronomy articles—from planetary science to cosmology—to motivate further inquiry.
Titan Is as Titan Does
December 23, 2012
Saturn's giant moon Titan keeps revealing mysterious dynamics in the here and now, leaving interpretation to fallible scientists who sometimes predicted otherwise.
Globular Clusters Look Young and Old: Is This Scientific Explanation?
December 19, 2012
Globular clusters supposedly all formed at the same time long ago, but some look young. How do astronomers rescue the belief that they are ancient groupings of stars?
Evolution of Flight: A Story Looking for Evidence
December 3, 2012
An evolutionary dogma is that land dinosaurs evolved into flying birds. When the claims are acid-washed with critical analysis, what evidence remains?
Two Studies May Indicate Problems for Vast Ages
December 1, 2012
Two articles in secular science literature point to possible upsets in long-age assumptions for the earth and mankind.
Flaky Cosmic Notion Gets Good Press
November 26, 2012
Does the universe grow like a giant brain? If anyone but a scientist said that, it would be in the cartoons.
Proteins Conduct Electricity

Biological solutions to physical challenges are inspiring new technologies.
Archer Fish Amplifies Muscle with Physics
October 25, 2012
The secret of the archer fish’s powerful spits has been discovered, and it isn’t powerful muscles. The fish that shoots bugs out of the air uses physics, a paper in PLoS ONE declared. By letting physics amplify the momentum in the drop shot out of the water, the fish achieves six times the wallop its […]
Butterfly Cities and Spider Optics
October 22, 2012
Skycrapers of the future may shine in brilliant butterfly colors. Optical biosensors may be made from spider webs. These are just a few of the engineering marvels coming from biomimetics—the imitation of nature.
Shining Light on Dark Energy
October 21, 2012
Fifteen years after cosmologists proposed the existence of dark energy, they have learned nothing about it. In “Cosmology: Out of the Darkness,” Matthew Chalmers discussed the current thinking of Brian Schmidt, who shared the Nobel prize in 2011 for discovering cosmic acceleration (actually, an inference based on light from supernovae; see 9/30/2012). “Fifteen years after […]
