Embryonic Stem Cell Decision Overturned

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

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

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”

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

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

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

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

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

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 […]

Go to the Cell, Thou Sluggard

Solomon ordered the lazy man, Go to the ant, thou sluggard; consider her ways, and be wise (Proverbs 6:6).  Today, he would probably tell lazy materialists needing wisdom to consider the cell.  Several recent scientific papers and news stories illustrate why materialism faces a stiff challenge from design features found in the fundamental units of […]

Human Genome Project Supports Adam, Not Darwin

Science magazine last week had a special series of articles on the 10-year anniversary of the Human Genome project.  Most of the articles expanded on how different the findings were from predictions.  The publication of the genome did not identify our evolution; it did not lead to miracle cures.  What it did most of all […]

Tipping Point for Embryonic Stem Cells?

At any time, courts could rule on whether funding of embryonic stem cell research can continue or must be halted.  Whichever way a decision is rendered, whether by Judge Lamberth on the legality of the NIH guidelines, or by the Court of Appeals for DC, the issue will probably wind up before the Supreme Court.  […]

How Bacteria Use Their Flagella

Do an imaginary mind-meld with a bacterium for a moment.  Visualize yourself encased in a membrane, surrounded by fluid.  You have no eyes, ears, or hands.  You need to find where food is, and avoid danger, so you have organelles that can take in molecules that provide information about what is going on outside, where […]

Extreme Biomimetics

Imitating spider silk or gecko feet is one thing, but some researchers are going to extremes to try to do what living organisms do. DNA railcar:  Researchers at University of Oxford have constructed a “programable [sic] molecular transport system” that travels like a railcar on DNA molecules, reported PhysOrg.  And that’s not all: they would […]

Molecules as Traffic Cops

One of the cutting-edge developments in cell biology and genetics is the realization that there are networks of molecules that are regulated by other molecules.  Some molecules stimulate growth while others repress it.  The dynamic interplay between signals, hormones, repressors and other processes somehow leads to “homeostasis” – a dynamic balance that is responsive to […]
