Your Nerves and Heart Depend on Cellular Pulleys, Latches and Switches

Biologists continue to peer closer and closer at cellular machines that work just like man-made ones, only at scales so tiny, they control individual atoms.  Of particular interest have been the gates in the membranes of cells that allow certain atoms in but keep others out.  A recent paper in Cell by an Australian team […]

Venter’s Synthetic Plagiarism Deflated by NY Times

How significant was Craig Venter’s achievement of a so-called synthetic genome?  Somewhat significant, but it pales in significance to creating life from scratch.  It was only like “peering over a fortress that is the mighty cell,” wrote Natalie Angier for the New York Times Monday, May 31.     The article was accompanied with a […]

Stem Cells: Hope, Politics, Charity, and Clarity

Those promising little cells that can differentiate into almost any tissue continue to make news – but they also continue to generate controversy.  Actually, only some of them generate controversy: the embryonic stem cells.  Not all of the articles about stem cells make that clear.  Defining life:  With the stroke of a pen, South Korea […]

Venter Group Plagiarizes Genetic Code

Is plagiarism a form of intelligent design?  We think of intelligent design in terms of God and creation, but in generic terms, I.D. only refers to purposeful, designed action by an agent – any agent, large or small, good or evil.  A planned murder, for instance, can be an evil form of intelligent design.  A […]

If Humans Build DNA Machines, Is It Intelligent Design?

Two teams have succeeded in building little robots that work on DNA tracks.  These resemble in many respects the machines that cells use to perform its functions on DNA.  No one denies that humans engineered their nanobots on purpose, but Darwinist scientists claim natural cellular machines evolved without purpose or design.  What’s the difference?   […]

Bacteria: Let’s Harness Those “Perfect Machines”

Ten Italian scientists have a novel idea.  They want to hitch up their wagons to bacteria and use them to power nanomachines.  It’s too much work to build such “perfect machines” from scratch, they said.  Why not just take advantage of what nature has already provided?     Their paper in PNAS1 is downright dreamy […]

Can Darwin Be Rescued from a New Eye Discovery?

Darwinists have claimed for years that the human eye is an example of bad design, because it is wired backwards – the photoreceptors are located behind a tangle of blood vessels and other material.  But then in 2007, German scientists found that cone-shaped cells called Müller cells act like waveguides that transmit the light through […]

Darwin’s Linux: Did Evolution Produce a Computer?

How is a cell like a computer?  Some Yale scientists asked that question, and embarked on a project to compare the genome of a lowly bacterium to a computer’s operating system.1.  Their work was published in PNAS.2  As with most analogies, some things were found to be similar, and some different – but in the […]

Update on Interplant Internet

One of the early “amazing” stories reported in these pages concerned the startling observation that plants use a kind of “email” system in their own interplant “internet” (see 07/13/2001).  What has been learned in the nine years since that story appeared?  Quite a lot, and another fascinating article about plant communication appeared this week in […]

Maxwell’s Demon Helps Run Your Muscles

James Clerk Maxwell once speculated that the second law of thermodynamics could be violated if an agent or “demon” could sort the hot and cold molecules at a barrier, thus overcoming the tendency toward thermal equilibrium.  Something like this has been found at work in the molecular machines in our muscles.  The actin-myosin motor is […]

Search for Intraterrestrial Life Scores Big

Single-celled organisms may be tiny, but what they lack in bulk they make up for in volume and importance.  Scientists have been appreciating more than ever the ubiquitous presence of microbes on our planet and the roles they play to sustain the biosphere.     PhysOrg reported that half of the world’s life may lie […]

Robotic Pothole Crew Keeps Your Genetic Highways in Good Repair

What a thought – a repair crew of molecular machines roaming the strands of your DNA, fixing errors 24 x 7.  It happens.  New techniques are showing the machines jumping from strand to strand like fleas, stopping at suspicious points, and fixing errors, reported Science Daily.  Dr. Bennett Van Houten (U of Pittsburgh Cancer Institute) […]

What Good Is Natural Selection without Progress?

Three papers recently claim to have seen natural selection.  None of them, however, identified a functional advantage that would have tied changes to novel benefits that could improve a species.  Yeast:  “New Type of Genetic Variation Could Strengthen Natural Selection,” trumpeted a headline in Science Daily.  It was about a study of two varieties of […]

Life Crams Stuff on the Long Road

This quote from UC Berkeley wins Stupid Evolution Quote of the Week: In the long evolutionary road from bacteria to humans, a major milestone occurred some 1.5 billion years ago when microbes started building closets for all their stuff, storing DNA inside a nucleus, for example, or cramming all the energy machinery inside mitochondria. Any […]

Life Leads the Way to Invention

Here’s a factoid for the party: a cell is 10,000 times more energy-efficient than a transistor.  PhysOrg tells us that “ In one second, a cell performs about 10 million energy-consuming chemical reactions, which altogether require about one picowatt (one millionth millionth of a watt) of power.”  This and other amazing facts lead to an […]
