Using Aliens to Titillate the Public
June 28, 2010
Geologists cannot even figure out our own planet (next headline), but some of them claim to know a lot about other planets – their geological history, and even their prospects for life.  Is it fair to tease the public with the L-word life when so much remains to be understood on the ground under our […]

Fish Feet: Can Evolution Add by Subtraction?
June 26, 2010
How did fish grow feet?  One would think that feet require adding a lot of new parts: bones, muscles, nerves, blood vessels, and additional supporting tissues.  Each of those would require genetic instructions and changes to embryonic development.  One evolutionist, however, feels that switching genes off paved the way to the invasion of land.  The […]

The RNA Code: Pseudogenes Functional, Help Prevent Cancer
June 24, 2010
A surprising function has been discovered for a “pseudogene” – an apparently mutated copy of a regular gene that till recently was thought to be genetic junk.  This pseudogene, reported in Nature today,1 not only has a function unrelated to the production of proteins, but a function that could save your life.  It is part […]

Can the Earth Thwart Darwinism?
June 23, 2010
Microbes were all set to evolve into complex life, but the ocean held them back.  That seems to be the thinking of Dr. Simon Poulton of Newcastle University.  “Toxic seas may have been responsible for delaying the evolution of life on Earth by 1 billion years,” PhysOrg reported.  That seems to imply that it would […]

Butterfly Wing Shimmer Done With 3-D Crystals
June 15, 2010
Those shimmering flashes of light seen on butterfly wings are not done with pigments.  They’re done with tiny, geometric crystals called gyroids stacked in 3-D patterns, scientists have found.  They are so effective at concentrating color, the scientists want to imitate the trick.     “A precise characterization of color-producing biological nanostructures is critical to […]

The Limits of Scientific Speculation
June 14, 2010
How far can a scientist speculate and get a respectful hearing, just because he or she is a scientist?  One case to examine is a story on PhysOrg, “The Chance for Life on Io” (see also Astrobio.net).  Jupiter’s innermost large moon Io might be considered the last place to look for life.  It is the […]

Planets Seen Forming! (or Dust Spreading )
June 13, 2010
Science headline writers were almost beside themselves with joy at the prospect of watching other planetary systems in the process of forming.  Science Daily nearly set a record with a large-print, bold, 22-word headline: “Zooming in on an Infant Solar System: For the First Time, Astronomers Have Observed Solar Systems in the Making in Great […]

Flagellum Replaces Parts on the Fly
June 12, 2010
A new study appears to show that the bacterial flagellum, a molecular rotary motor that has become iconic of the intelligent design movement, can repair parts of its rotor while it is rotating.  The results of the study by Oxford University were published in PNAS,1 and were also the focus of a Commentary in PNAS […]

Darwin’s Sweatshop: Why Ethiopia Made People Hairless
June 10, 2010
Five scientists think they have figured out why people walk upright and don’t have fur like other mammals.  They had to evolve in Ethiopia, where it is hot.  This led to the loss of body hair, and the evolution of sweat glands and other adaptations to deal with the heat.     It’s not that […]

Plants Have Memories
June 9, 2010
June 09, 2010 — Have you ever noticed how plants have an uncanny ability to know, without eyes or brains, when the time has come to bloom?  Even when spring comes early or late in some years, they sense the right time, and out come the flowers.  This is even more remarkable when you consider […]

Your Nerves and Heart Depend on Cellular Pulleys, Latches and Switches
June 4, 2010
Biologists continue to peer closer and closer at cellular machines that work just like man-made ones, only at scales so tiny, they control individual atoms.  Of particular interest have been the gates in the membranes of cells that allow certain atoms in but keep others out.  A recent paper in Cell by an Australian team […]

Whale Evolution: Hurry Up and Wait
June 3, 2010
Whales evolved really fast, then just swam around with nothing to do for tens of millions of years.  “Whales Evolved in the Blink of an Eye” wrote Brett Israel for Live Science about a new study that claims “Whales evolved explosively fast into a spectacular array of shapes and sizes” about 35 million years ago, […]

Venter’s Synthetic Plagiarism Deflated by NY Times
June 2, 2010
How significant was Craig Venter’s achievement of a so-called synthetic genome?  Somewhat significant, but it pales in significance to creating life from scratch.  It was only like “peering over a fortress that is the mighty cell,” wrote Natalie Angier for the New York Times Monday, May 31.     The article was accompanied with a […]

Fooling Around with OOL
May 31, 2010
Origin of Life (OOL) research is one of those areas in science where one doesn’t have to make any real progress, as long as he or she looks busy.  Anything the scientist says, no matter how speculative, or even foolish, is likely to be taken seriously, because the alternative – creation – has already been […]

Darwin in Space without a Helmet
May 26, 2010
“Space agencies may one day have Charles Darwin to thank for the longevity of their spacecraft,” began an article in New Scientist.  This seems a strange thing to write about a biologist who knew nothing of space travel.  “The life expectancy of a popular type of ion engine has been almost doubled using software that […]
