Follow the Leader: Nature
June 21, 2011
Ever since biomimetics (the imitation of nature) gradually emerged around 2002 and really took off in 2005, it has not slowed down. Over 90 previous entries in these pages have reported teams all over the world seeking out natural designs for ideas. The reports have accelerated in recent years to the point where there is only space for short summaries that give a taste of the wide variety of engineering work taking inspiration from plants, animals, and even cells. You yourself might inspire some inventor. Here are a few more highlights from recent adventures in biomimetics.

Stem Cell News
June 20, 2011
Stem cells continue to be hot subjects for research. They are divided into two basic “political” parties: embryonic stem cells (ES), which raise ethical issues about tampering with human life, and adult stem cells (AS), found throughout the body, which have no ethical issues and show the most progress for therapy. The latter include the induced pluripotent stem cells (iPS), coaxed from adult cells to recover the ability to differentiate into multiple tissue types. Even though AS is leading, some scientists are still demanding federal funding for ES.

Genetic Entropy Confirmed
June 5, 2011
In Darwinian evolution, variations must add new information to produce innovations. Neo-Darwinism ascribes those variations to genetic mutations. In 2005, geneticist John Sanford (Cornell) argued that the accumulation of mutations always decreases fitness in a process he called “genetic entropy.” The downhill trend is amplified by a number of factors, including selection interference and epistasis (interactions between mutations). Now, genetic entropy from epistasis has received support by two new papers in Science.

Biological Information Symposium a Success
June 4, 2011
Friday morning June 4, participants were on their way homes across America and in Europe from a successful conference entitled Biological Information: New Perspectives. They had come to hear leading lights in the Intelligent Design movement deliver 27 scientific presentations on a variety of subtopics under the umbrella theme of information in biology. From all appearances, everyone had a great time of fellowship, encouragement and intellectual stimulation. No protesters or critics detracted from the event—partly because it was not widely advertised, in order to protect the identity of those wanting to take part without jeopardizing their careers.

Embryonic Stem Cells Left in iPS Dust
May 23, 2011
A few years ago, scientists were clamoring for access to human embryos for stem cell research. Now, the discovery of induced pluripotent stem cells (iPS) from human skin and other adult tissues has sidetracked interest in embryonic stem cells. The momentum is clearly going with iPS. Is there any longer a need for embryonic stem cell research? (includes 9 bullet topics)

Intelligent Design Found in Bacteria
May 1, 2011
Poetry has been found in a bacterial genome.  We know it was intentional, because we know the poet who did it: Christian Bok.  The BBC News tells how Bok “encoded his verse into a strip of DNA and had it inserted into a common bacterium, E. coli.”  Would scientists of the future be able to […]

Embryonic Stem Cell Decision Overturned
April 30, 2011
Judge Lamberth’s decision to block federal funding of embryonic stem cell (ESC) research last fall (09/03/2010) has been overturned by a 2-1 vote in a federal appeals court.  PhysOrg called this a “major victory to President Barack Obama’s administration.”  Theistic evolutionist Francis Collins, head of the NIH, expressed delight at the reversal.  The earlier decision […]

More Complexity in Simplicity Found
April 28, 2011
Primitive things aren’t.  That seems to be a common thread in some recent stories that found more complexity in simple living things. Box jellyfish eyes:  Jellyfish are among the simplest of animals, so why do box jellyfish have two dozen eyes but no brain?  Some of these eyes have now been found to detect features […]

Why Stuff Evolves: Not Having Stuff Would Be Terrible
April 23, 2011
The delicate yet effective choreography of DNA Damage Repair was described by Lawrence Berkeley National Lab in terms of amazement: “Safeguarding genome integrity through extraordinary DNA repair.”  DNA repair is essential for health: “To prevent not only gene mutations but broken chromosomes and chromosomal abnormalities known to cause cancer, infertility, and other diseases in humans, […]

Complexity Appears “Earlier than Thought”
April 14, 2011
Widely-separate branches of science seem to converge on a common puzzle: complexity goes farther back than scientists expected – evolutionary scientists, that is. Cosmology:  More evidence has come that galaxies formed very early.  A mature galaxy detected through gravitational lensing was announced by the Hubble Telescope team, with an estimated redshift of 6.027.  In the […]

Adult Stem Cell Advances Continue
April 7, 2011
The momentum for stem cell therapy is still on the side of adult stem cells (ASC), not embryonic stem cell (ESC) research.  Here are some recent findings: Blood vessel repair:  A press release from King’s College London says, “Scientists from King’s College London have uncovered the first genetic evidence that shows cells found on the […]

Your DNA Repairman Is Handy as an Octopus
March 27, 2011
Some 10 times a day in a given cell, your DNA breaks on both strands.  This is an emergency.  Unless repaired quickly, serious diseases, like cancer, can develop.  But no fear: the first responder is an octopus-shaped protein complex that rushes to the rescue, wraps around the damaged site, and brings in all the parts […]

Neurons Know What to Do
March 27, 2011
Neurons are among the most vital cells in the body: after all, your brain is largely composed of neurons.  Neurons are transmission lines of information that keep a body in touch with itself and the world.  None of the other body organs would work without neurons.  The increasingly powerful tools of microscopy are allowing neuroscientists […]

We Are Filled with Viruses
March 26, 2011
Viruses have a bad connotation.  We immediately think of the ones that cause disease: “I’ve got a virus,” you say when feeling under the weather.  Actually, you have trillions of them all the time, even in the best of health.  A single gram of stool sample can have 10 billion of them!  What does that […]

Double Ratchet Found in ATP Synthase
March 16, 2011
ATP synthase, the rotary engine in all living things, has another trick in its design specs: a ratcheting mechanism that improves the efficiency of ATP synthesis.  ATP is the “energy currency” of cellular life, so the efficiency of production of ATP is of vital importance.  (For background and animation, see CMI article.)     Three […]
