Rubisco “Highly Tuned” for Fixing Atmospheric Carbon
June 22, 2006
Rubisco sounds like a brand of cracker or something, but it’s actually an air cleaner your life depends on.  It’s an enzyme that fixes atmospheric carbon for use by photosynthetic microbes and plants.  In doing so, it sweeps the planet of excess carbon dioxide – the greenhouse gas implicated in discussions of global warming – […]

Reach Out and Touch Some Robot
June 13, 2006
The news media were excited to report an advance in materials science last week that could pave the way for touchy-feely robots (see BBC News, News @ Nature, LiveScience and National Geographic News, for instance).  Two scientists produced a thin film with touch resolution comparable to that of a human finger, an order of magnitude […]

Bioneers Update: International Conference Held on Animal-Inspired Design
May 13, 2006
Georgia Tech came out with a press release about progress at their Center for Biologically Inspired Design (CBID) that opened last year (see 10/29/2005).  At a two-day conference May 11-12, international representatives from 20 institutions shared their inspirations on how nature can “help them solve some of the most complex problems of the day,” just […]

Insects Lead the Way
April 28, 2006
Why engineer things from scratch, when we can imitate nature?  Two recent examples come from the world of insects.  A press release from UC Berkeley begins, “Using the eyes of insects such as dragonflies and houseflies as models, a team of bioengineers at University of California, Berkeley, has created a series of artificial compound eyes.”  […]

Experimental Biologists Look to Animals for Inspiration
April 5, 2006
Whether insects, fish, birds or mammals, animals have a lot to teach scientists and engineers.  Here are some recent stories that begin to answer, “How do they do that?” with hopes that humans might be able to mimic their feats. Hard sponges:  Aimee Cunningham in Science News (03/25/2006; 169:12, p. 184) described the astonishment Joanna […]

What’s Darwin Got to Do With It?
February 28, 2006
Is evolutionary theory useful?  We saw Donald Kennedy et al. claiming last week (see 02/24/2006) that doctors need training in evolutionary thinking.  This week, Christopher Beard (U of Pittsburgh Medical Center) claimed that a study of dinosaur evolution can help doctors understand human lower back pain (see EurekAlert).  These, however, are announcements after the fact.  […]

Alien Engineering: Is It Intelligent Design?
February 16, 2006
The SETI Institute finished airing a 2-part series on the History Channel called Alien Engineering (it will be rebroadcast on Feb. 18).  The series, featuring SETI Institute scientists Seth Shostak and Frank Drake, asks the following questions: Prepare for an exercise in imagination.  Suppose that an alien spacecraft crashed in the desert and we humans […]

Eyes on the Prize: Science Sees Gold in Biomimetics
November 19, 2005
A fly eye made the cover of Science this week.1  It’s not that the compound eye is interesting to entomologists; MSNBC News picked up on the real message: “Animal eyes inspire new technology – Researchers learn optics lessons from biology.”  The cover story is about biomimetics, or reverse-engineering nature.  Scientists are looking for ways to […]

Scientists Learning How to Harness Cellular Trucks
November 15, 2005
In an article that blurs the line between biology and technology, a press release from the Max Planck Institute (see EurekAlert for English translation) described the amazing performance of the nanoscopic trucks that ride the cell’s microtubule superhighways.  Kinesin and myosin motors, fueled by ATP, usually “sprint” on the trackways for short distances, but working […]

Living Wonders at a Glance
November 4, 2005
Here is an assortment of recently-reported biological marvels at the cellular level.  Researchers into creation and evolution explanations may wish to delve into these more deeply. Clock Conductor:  The brain is a “time machine,” reports EurekAlert on research at Duke University about the human biological clock.  Each structure in the brain has a resonant frequency […]

Georgia Tech “Bioneers” Plagiarize Mother Nature to Advance Science
October 29, 2005
“Copying the ideas of others is usually frowned upon, but when it comes to the work of Mother Nature, scientists are finding they can use nature as a template.”  That’s how an interesting press release from Georgia Tech begins (reproduced on EurekAlert) about a new center on campus called the Center for Biologically Inspired Design […]

Sponges Use Fiber Optics for Interior Lighting
November 20, 2002
51; Sponges are among the simplest of multicellular organisms, but they contain an advanced human technology: fiber optics.  In a case of reverse biomimetics, scientists have determined that one of the products of proud human engineering was already at work in a lowly sponge.     Fiber optical properties of sponge spicules was already known, […]

Flight Design Inspires Research
November 20, 2002
There are flying machines hovering over our planet that can turn on a dime, making rapid 90-degree turns.  Their instruments process images ten times faster than we can, and possess precision gyros that tell them how fast they are rotating in space – yet their computers are smaller than the head of a pin.  They’re […]

Intelligent Design Put to Good Scientific Use
November 20, 2002
51; Evolutionists try to portray intelligent design as something outside of science that threatens science.  Actually, the techniques of intelligent design are hard at work within science, and have been for some time.  Examples are not hard to find on a variety of fronts. Archaeology:  “The ability to tell the difference between crystals that formed […]

Mutating Evolution Into Design
July 20, 2002
51; The word evolve gets used in funny ways.  As Paul Nelson has noted, it often becomes a Designer substitute.  Look how an article in New Scientist employed it: Could a 3D printer help to create in minutes what nature took millions of years to evolve – the perfect insect wing? Tiny robotic insects would […]
