Flatlife Has More Genes Than It Needs
August 23, 2008
The genome of a placozoan (“flat animal”) shows more complexity than one would expect for a simple life form.  According to evolutionists, it shows that even a barely-differentiated animal presumably ancestral to complex animals had the genetic toolkit of its more-advanced descendents.     Trichoplax adhaerens is a slimy-looking thing that sticks to aquarium walls.  […]

Membrane Switches Keep Your Brain Humming
August 14, 2008
Tunnels with rotating gates and rocker switches – this sounds like mechanical engineering.  It’s the machinery that helps power your brain, reported scientists from UCLA and the Pasteur Institute.     Their paper in Science described the structure of just one of many kinds of membrane channels.1  Cell membranes are lined with elaborate one-way gates.  […]

Admissions of Ignorance in Evolutionary Theory
August 11, 2008
For a scientific idea some have proclaimed as a fact no longer in need of proof, and as well-established as gravity, Darwin’s theory of evolution still reveals surprising weaknesses when its defenders speak about the details.  Detecting these weaknesses requires tuning out the media hype, and tuning into scientific papers and pro-evolution journals where evolutionary […]

Adult Stem Cells Race Ahead; Embryonics Falter
August 7, 2008
Major advances are being made with induced pluripotent stem cells (iPS), stem cells reconstituted from adult tissues, while interest in embryonic stem cells (ES) seems to be drying up.     Both Nature and Science reported advances in iPS technology last week.  Nature reported that the number of factors needed to reconstitute pluripotent stem cells […]

Tree of Life in the Genes? Not Yet
July 23, 2008
Now that we have hundreds of animal genomes in the bank (the GenBank), is Darwin’s tree of life becoming visible?  If the image is present, it is extremely weak, said Michael J. Sanderson of the Department of Ecology and Evolutionary Biology at University of Arizona.  Writing for Science,1 he showed that only a small fraction […]

Mangrove as Metaphor
July 22, 2008
The mangrove – that shoreline tree with the salt-tolerant roots that grows into dense thickets – is the fulcrum of two unrelated news stories.  It never met a force it couldn’t handle.  It also provides metaphors for evolution and creation.     PhysOrg reported that the mangrove is a key to saving lives.  “The replanting […]

Cellular Trucks Use Moving Highways
July 18, 2008
Imagine how cool it would be to get in your car and have the road do the driving.  The highway would stretch or shrink, moving this way or that, till you saw your destination and hopped off.  That appears to be what the cargo-bearing motors do in the cells in your body.  A new paper […]

The Cro-Magnon Were Europeans
July 16, 2008
There’s no genetic difference between Cro-Magnon Man and modern Europeans, a genetic study reported by Science Daily.  Researchers took extra care to avoid contamination of bones found in southern Italy, they said.  They claimed Cro-Magnon people were able to maintain genealogical continuity for 28,000 years, remaining distinct from Neanderthals, whom they said lived in Europe […]

Is Artificial DNA Intelligently Designed?
July 15, 2008
Japanese chemists have made a new kind of DNA, reported Science Daily.  It resembles natural DNA, but is composed of bases that are shorter, modified forms of the ones cells use.  “The finding could lead to improvements in gene therapy, futuristic nano-sized computers, and other high-tech advances,” the article says. An evolutionist should extend his […]

It’s Networks All the Way Down
July 8, 2008
New ways of seeing biology are finding life is full of networks.  At both ends of the complexity scale – from humans to bacteria – complex interactions are the rule.  Two teams studying different phenomena had the same reaction – astonishment. Bottom-up complexity:  Who would have thought one of the simplest life forms has a […]

Amazing Cell Tricks: Contour Map Navigation
July 5, 2008
Watch a cell divide, and if things go well, it always divides in the middle.  How does a cell figure out where its middle is?  It follows its contour map.  PhysOrg titled its entry, “Dividing cells find their middle by following a protein ‘contour map’.”     Cell division, or cytokinesis, is a precisely-controlled operation […]

How to Tell an Evolutionary Story
July 4, 2008
Thanks to Science Daily, we now know that “Evolutionary Origin Of Mammalian Gene Regulation Is Over 150 Million Years Old.”  The proof is easy.  It is so easy, in fact, that no proof is necessary.  One can merely assume it is true.  Trust them; they are scientists, after all. Here is how the E word […]

Birds of Different Feathers Evolve Together
June 26, 2008
Are pigeons like parrots?  Are hummingbirds like hawks?  And are falcons unlike eagles?  Scientists are all a-flutter after results of a massive genetic comparison of birds has put some members in unlikely pigeonholes.  “The largest ever study of bird genetics has not only shaken up but completely redrawn the avian evolutionary tree,” said Science Daily.  […]

Bacterial Flagellar Motor Has a Protein Clutch
June 24, 2008
The bacterial flagellum, the whiplike outboard motor that has become an icon of intelligent design, has another artificial-looking part: a clutch.  Science reported this in “machine language” as follows:1 The bacterial flagellum, powered by a motor that generates 1400 pN-nm of torque, can rotate at a frequency of greater than 100 Hz.  EpsE [the clutch […]

Animal Patterning Keeps Scientists Puzzle-Solving
June 23, 2008
Here’s a fascinating area of research for a budding young scientist: the development of animal patterns.  Look at the dazzling wing patterns on butterflies in an illustration on Science Daily or consider a zebra’s stripes.  How do such patterns emerge from a single fertilized egg?  “Although this has been studied for years,” said a researcher […]
