Plants Outsmart Darwin

There are wonders in plants that continue to be uncovered with the tools of science.  Two recent papers in PNAS lend support to the feeling that plants are smarter than assumed. Trash collection:  Humans usually only employ one trash collection service, but plants have two.  Four Chinese investigators found redundant pathways in plant cells for […]

Brain Synapse Machinery Is Finely Tuned

The New York Times published a brief article on brain facts that is astonishing, when you think about all that goes on in thinking.  Nicholas Wade reported on a new inventory of the proteins involved in the synapses, the key junctions between neurons.  The research team, led by Seth Grant of the Sanger Institute near […]

Plant Wonders Are in the Details

When you step on a weed growing out of a crack in the sidewalk, do you have any idea what kind of amazing machinery you stepped on?  Maybe a closer look will help. Communications and switching systems:  When a seed sprouts, it needs to first grow upward in the dark while trying to protect itself.  […]

Cells Manage Stress and Death

Like soldiers in a foreign land, cells sometimes find themselves in unexpected situations.  Key equipment breaks down, or the environment puts stress on their resources.  Without the ability to adapt, they could perish – and in worst-case scenarios they must, like a squadron under ambush with no way out.  In such cases, like spies carrying […]

NASA Finds Life on Earth; or,Arsenic and Old Lake

A NASA teaser about an announcement coming Dec 2 that will “will impact the search for evidence of extraterrestrial life” had watchers on edge.  PhysOrg said, “Speculation that life has been discovered beyond Earth exploded on the Internet after NASA announced plans for a briefing involving scientists who study unusual life forms.”  It wasn’t to […]

Is Life More than Sewage?

Look at the sewer pipe accompanying an article on Science Daily.  The article claims that a bacterium in the sewer water is a “missing link” in our evolution.  How can this be?     For a long time, evolutionists have tried to bridge the gap between bacteria, which lack a nucleus, and eukaryotes which have […]

Even Your Trash Can Is High-Tech

Cells have the same problem as cities: disposing of trash.  Each of your cells has elaborate trash collector machines that not only dispose of damaged or unneeded proteins – they recycle them, too.  The structure of the proteasome, a fragile machine difficult to crystallize for imaging, has just become clearer thanks to researchers in Germany […]

Stem Cells of the Adult Kind Steal the Headlines

Stories about stem cell research need to be divided into two sections: those about adult stem cells (AS), which have no ethical ramifications, and stories about embryonic stem cells (ES), which raise many issues about the sanctity of human life.  As usual, most of the actual clinical progress is being made with adult stem cells […]

Evolutionists Try to Out-Complex Behe

The phrase irreducible complexity has reluctantly entered the working vocabulary of evolutionary biologists, though they usually disparage its source (Dr. Michael Behe, leading proponent of intelligent design).  The latest evidence is a paper in Science that was titled with an obvious play on words and an attempt to refute Behe’s principle.  They called it “irremediable […]

Cells Can Be Transformed

An astonishing feat has been performed in a Canadian lab: scientists turned human skin cells into blood cells.  Bypassing the need for stem cells, the technique provides hope for a supply of blood from a person’s own skin. Live Science calls it a “modern miracle.”  The technique avoids “the ethical concerns concerning embryonic stem cells […]

All Kingdoms of Life Have Ideas We Need

Inventors aren’t partial.  They are willing to find inspiration in plants, animals, and microbes.  Here are three examples showing that all kingdoms of life have great engineering ideas that researchers involved in biomimetics are seeking to understand. Plants:  We don’t fight walled cities with catapults any more, but storing elastic energy can still be useful.  […]

Purpose-Driven Science Ignores Darwin

While some Darwinists feel that the Intelligent Design (ID) movement is a major threat to science, many scientists unconnected to ID are acting as if it provides for them a more fruitful approach to research.  Several recent examples illustrated what might be called a silent “de facto” intelligent design movement. Purposeful proteins:  PhysOrg reported work […]

Cells Know Their Physics

At the microscopic level of cells, forces come into play that are unfamiliar to us at the macro level: quantum mechanics, Brownian motion, and subtle elastic forces that we might overlook.  Two recent papers in the Proceedings of the National Academy of Sciences explored physical mechanisms cells use to good advantage.  Good thing cells know […]

Automatic Turnstiles Found in the Cell

One of the things students learn about in high school biology classes is active transport: the ability to control flow through a semi-permeable membrane.  Contrary to osmosis, in which the flow goes naturally from high concentration to low concentration, cell membranes employ active mechanisms to push or pull the molecules through their membranes according to […]

Hairy Bacteria Walk and Talk

Little hair-like projections on some bacteria, nearly invisible with light microscopes, are not just for decoration.  They do amazing things – as a pair of recent discoveries brought to light.  They help bacteria walk and talk. But can they dance?  Bacteria swim, but they also land on surfaces – and when they do, they put […]
