DNA Translation Has Codes Upon Codes
December 17, 2007
The DNA code is protected by another code, and is read with a machine that reads a third code.  This is an emerging picture from ongoing research into DNA transcription, as reported in Science.1     In the 1950s, scientists were astonished to find a code at the genetic basis of life.  DNA’s four-letter alphabet, […]

Will Adult Stem Cells Cure Sickle Cell Anemia?
December 9, 2007
It’s been just weeks since two labs announced success harvesting pluripotent stem cells from skin cells (11/20/2007), and already beneficial applications are in sight.  Science Daily and Live Science reported on initial tests that show the new “induced pluripotent stem cells” offer hope for millions afflicted with sickle-cell anemia.  Though it’s too early to tell […]

Cell Gatekeepers: Diverse, Complex, Accurate
December 2, 2007
Cargo moves around rapidly and ceaselessly in every cell.  Some moves in and out of the external membrane, and some moves in and out of organelles and the nucleus.  In a system of protected domains surrounded by impermeable membranes, how does the cell control what should pass?  Details of the amazing gatekeeping mechanisms embedded in […]

Flowering Plants Do Big Bang in Darwin’s Face
December 1, 2007
There’s a big bang in botany.  The flowering plants, reported Science Daily, “evolved very quickly into five groups.”     The claim is based on the investigation of plant genes by scientists in Florida.  Their work “showed that a stunning diversification of flowering plants they are referring to as the ‘Big Bang’ took place in […]

Darwin As Prognosticator
November 15, 2007
How good was Darwin at making predictions?  A good scientific theory should make predictions, at least according to a common assumption about science.  PBS thinks Darwin hit a home run, according to an interactive feature on the website for Judgment Day, the documentary about evolution vs intelligent design shown on Nova this week (11/14/2007).  The […]

More Cell Codes and Authentication Mechanisms
November 13, 2007
Here are more “cool cell tricks” that ensure a smoothly-functioning system inside the cell that can adapt to changes while protecting assets. Ribosome code:  Why don’t all ribosomes look alike?  Perhaps they know a secret code.  Another possible coding mechanism has been found in ribosomes, those important organelles in the cytoplasm that translate messenger RNA […]

Mighty Mouse Has Arrived
November 6, 2007
Geneticists at Case Western Reserve University have genetically engineered mice that “can run five to six kilometres at a speed of 20 meters per minute on a treadmill, for up to six hours before stopping,” according to a report on the BBC News.     Professor Richard Hanson explained, “They are metabolically similar to Lance […]

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 […]
