Evolutionary Predictions Fail Observational Tests
March 8, 2007
Lately, some expectations by evolutionists have not been fulfilled.  Here are several recent examples of evolutionary upsets: Dinobird genes cook up scrambled eggs:  Scientists expected that the dinosaurs presumed ancestral to birds would show a decreasing genome size.  The thinking was that the cost of maintaining a large genome takes its toll on flight.  In […]

Watch a Ribosome in Action
February 21, 2007
A remarkable article about a remarkable machine: that’s what Chemical and Engineering News has published about the ribosome, a molecular machine vital to everything alive in the world.  Stu Borman’s article lavishes praise on the details of this assembly-line factory that translates RNA into proteins.  He surveys the history of investigation into the ribosome’s secrets.  […]

Blind Cave Fish: Can Darwinism Be Credited for “Regressive Evolution”?
February 16, 2007
It is a worldwide phenomenon that cave creatures go blind.  Some cave fish lose their eyes entirely; in others, the eyes shrivel and lose function.  In many cave fish, scale pigmentation also changes.  Are these gradual modifications due to natural selection, Darwin’s mechanism of evolution, or to genetic drift?  Darwin himself could not see any […]

Cells Perform Nanomagic
February 13, 2007
The cell is quicker than the eye of our best scientific instruments.  Biochemists and biophysicists are nearing closer to watching cellular magic tricks in real time but aren’t quite there yet.  They know it’s just a trick of the eye, but it sure is baffling how cellular machines pull off their most amazing feats.  Think, […]

Contingency and the Structure of Life’s Building Blocks
February 6, 2007
Some Yale scientists found they could construct protein-like molecules using amino acids of a type not found in living things.  They found that beta-amino acids can fold into shapes similar to the proteins made of alpha-amino acids used in living things.  Beta-amino acids have an extra carbon on the backbone.  “Yale chemists show that nature […]

Cell Quality Control Runs a Tight Ship
January 31, 2007
Without the surveillance and rapid response of quality control, cells would collapse and die.  Here are some recently-published examples of nanoheroes in action. Plant checkpoints:  Picture a child watching the wonder of a seedling breaking through the soil into the light for the first time.  Within hours, the ghostly-white stem turns green, and a day […]

Cells Perform Sporting Interactions
January 31, 2007
The components of living cells perform such acrobatic moving interactions, one would think they are having fun.  Here’s the news from the Wide World of Cellular Sports. Speedway:  A news release from Penn Medicine talks about how motor proteins step on the gas and the brakes in their motions around the cell.  The announcer from […]

Cell Membrane Has Ticket-Operated Turnstiles
January 27, 2007
Cells are like castles surrounded by walls.  A wall without gates, however, would prevent commerce and trap the inhabitants inside.  The cell has ingenious gates that control the flow of goods and services through its outer membrane under tight surveillance and quality control.  This controlled flow, as opposed to passive diffusion or osmosis, is termed […]

The Evolution of Electrical Engineering:  An Imaginary Tale
January 17, 2007
Nerves carry electrical impulses.  Ipso facto, they are subject to laws of physics concerning conductance, capacitance, and resistance.  Getting a signal from one end of an animal to the other in time can be a matter of life and death.  In order to maintain optimum levels of electrical conductivity to meet their lifestyle requirements, animals […]

Are Cellular Motors Related by Evolution?
January 5, 2007
Just because two things go round and round, does that make them related by common ancestry?  A Japanese team thinks so.  A bacterial flagellum rotates (06/04/2002).  So does ATP synthase, though it is about 10 times smaller (04/30/2004).  Publishing in PNAS,1 these researchers looked for a relationship, and noted that these two motors bear some […]

This Bacterium Moves Like a Tank
January 3, 2007
Mark McBride (U of Wisconsin) has been trying for a decade to figure out how a gliding bacterium glides.  His conclusion: the microbe has tire treads like a conveyor belt that make it roll over a variety of surfaces, like an all-terrain vehicle.     According to a U of Wisconsin press release, the Department […]

In Science and Politics, Expect the Unexpected
December 29, 2006
Two findings reported this month illustrate how science changes.  Paradigms and policies can have their scientific underpinnings yanked out from under them, causing both consternation and opportunities for new ways of thinking. Bring back the acid rain:  Pick your poison: acid rain or global warming.  Acid rain was the bogeyman of the 1980s, leading to […]

Incredible Stasis in Evolution: What Does It Mean?
December 26, 2006
Quite often in phylogenetic research, evolutionists find examples of extreme conservation of genes or traits.  How they explain the lack of change is almost as interesting as the phenomenon itself.  Here are two recent examples. Your cousin the shark:  Surprise: you have more in common with horn sharks than bony fishes do.  Craig Venter’s international […]
