ID Support from Unlikely Quarters
November 27, 2006
While Nature 11/24 described intelligent design (ID) as a threat to science, support for it came from two new scientific books reviewed in the same issue.  Both of them, while not using the phrase intelligent design, deal with concepts that imply science must reach beyond material causes. Just right universal soup:  Jim Al-Khalili (U of […]

Urchin Genome Hyped by Media as Human Cousin

You’ll Love Beetle-Foot Tape
November 6, 2006
If beetles can do it, scientists should be able to: climb the wall, that is.  Some researchers at Max Planck Institute have invented an adhesive that sticks to glass like beetle feet.  The secret was to manufacture thousands of microscopic pads that adhere to smooth surfaces by van der Waals forces (the attraction of neighboring […]

Oxygen YoYos and Wings
October 18, 2006
Molecular oxygen: you can’t live with it, and you can’t live without it.  We breathe it in constantly or else we would turn blue and die within minutes.  Yet we take antioxidants because of the harm that oxygen radicals can wreak in our cells.  Like fire, it is a useful substance, but only when tightly […]

Should Elephants and Lions Be Reintroduced to North America?
October 2, 2006
Believe it or not, some scientists think large mammals that existed in North America in prehistoric times should be brought back.  This is called “rewilding,” in hopes of healing some of the ecological disruption caused when early humans “played a significant role in their demise 13,000 years ago.”  A dozen scientists provided a detailed proposal […]
