Month-End Close-Out
October 31, 2007
Sometimes the creation-evolution news comes in too fast.  Here’s a baker’s dozen from the October shelf, lest they go stale; time to start a new batch for November. Charity begins at worldview:  David Cyranoski in Nature (450, 24-25, 10/31/2007) investigated why the level of charitable giving in prosperous Japan is a tenth of that in […]

Cilia Are Antennas for Human Senses and Development
October 26, 2007
The little hair-like projections on cells, called cilia, have more functions than previously believed.  A press release from Johns Hopkins University said that researchers found cilia are important for the sense of touch – particularly, for heat sensation.  In fact, cilia are implicated in at least three of the five traditional senses.     The […]

Searching for Natural Selection in a Wildflower
October 19, 2007
Evening snow (Linanthus) is an amazing little wildflower that adorns desert areas of southern California.  Its blossoms open in the evening, spreading fragrance across a harsh landscape.  Two varieties have been noticed; one with white flowers, and one with blue flowers.  Scientists noticed that the white ones sometimes grow on one side of a ravine, […]

Make Your Face Sparkle With Diatoms
October 10, 2007
Human engineers may join forces with cellular architects to produce the next generation of paints, cosmetics and holograms, reported Science Daily.  Scientists are finding ways to harness the rapid growth of diatoms.  Manufacturing consumer products with these properties currently requires energy-intensive, high-temperature, high-pressure industrial processes that create tiny artificial reflectors.  But farming diatom shells, which […]

Darwin Saves Junk, Makes Treasure Out of It
October 5, 2007
The Stupid Evolution Quote of the Week award goes to a press release from the Howard Hughes Medical Institute, which began by personifying Evolution1 as a tinkerer in its own junkyard:   Evolution has mastered the art of turning trash to treasure – though, for scientists, witnessing the transformation can require a bit of patience.  […]

Bacteria and Plants Know Network Tech
October 1, 2007
An article on Science Daily says, “plants have their own chat systems that they can use to warn each other.”  Many herbal plants such as strawberry, clover, reed and ground elder naturally form networks.  Individual plants remain connected with each other for a certain period of time by means of runners.  These connections enable the […]

Molecular Machines Under the Nanoscope
September 28, 2007
Seeing machines just billionths of a meter long seems impossible, but cell biologists are now routinely looking into the cellular black box.  Using indirect but powerful methods, they can actually begin to visualize the gears and wheels and cogs of the protein machines that make life possible.  Some of our favorite cell gadgets were examined […]

Don’t Just Sit There; Evolve
September 27, 2007
Have you ever wondered why your body doesn’t evolve?  After all, it is kind of like a population of trillions of organisms.  Why shouldn’t it follow the rules of natural selection?  Philip Ball asked this question in News@Nature recently.  “Evolution is usually thought of as something that happens to whole organisms,” he teased.  “But there’s […]

Stem-Cell Advocates Try to Shield Ethical Concerns
September 26, 2007
Would an embryonic stem cell by another name cease being human?  Several recent articles on embryonic stem cells are going beyond just touting the potential cures from the controversial research, which involves creating and destroying a human embryo.  Some are blurring the line between embryonic and adult stem cells (cf. 12/02/2006) and attempting to avoid […]

Upsets: Assumptions About Genes, Atmospheres Challenged
September 24, 2007
It’s not fun when a whole superstructure of scientific theories and models is found to rest on a shaky foundation.  That’s just what may be happening in two very different fields: genetics and planetary science: Lateral pass to the opposing team:  Building evolutionary trees by comparing genomes was supposed to be simple.  Sure, geneticists knew […]

Thermodynamics: The Real Theory of Everything
September 23, 2007
Need a theory of everything?  Try thermodynamics.  Mark Haw reviewed a new book by Peter Atkins on the subject in Nature,1 Four Laws that Drive the Universe (Oxford, 2007).  He had high praise for the achievements of the “19th century grandees” Joule, Maxwell and Kelvin: Thermodynamics ought to be the cornerstone of any scientist’s understanding […]

Do Genes Reveal the Cambrian Explosion?
September 4, 2007
A Croatian geneticist believes he can find the Cambrian Explosion in the genes.  Science Daily told about Tomislav Domazet-Loso from the Rudjer Boskovic Institute in Zagreb, whose team employed a “novel methodological approach in evolutionary studies” they called “genomic phylostratigraphy.”  Looking for a “genetic trigger” for the Cambrian explosion, they hoped their method can “shed […]

Mystery of the Ultraconserved Elements, Cont.
August 18, 2007
ejerano et al reported ultraconserved elements in the human genome (05/27/2004).  These were non-coding regions that, for some unknown reason, showed no evolution between mouse and human – a time span over tens of millions of years.  Since many of these ultraconserved regions are also found in bird genomes, they added that some genetic regions […]
