How Does the Emperor Penguin Dive So Deep?
December 1, 2006
Using a small recorder mounted on an emperor penguin, researchers at Scripps Institute measured the bird diving as deep as 1,800 feet – six times the depth any human has survived unassisted.  This is much deeper than scientists had expected.  Live Science surmises that if we could figure out how they do it without getting […]

Little Animals, Big Technologies
November 28, 2006
You can’t always say bigger is better.  In the animal world, some of the smallest critters have capabilities that belie their size and compare well with their less dimensionally-challenged brethren.  Bee secure:  Honeybees are being trained to sniff bombs.  Really.  Read all about it in a press release from Los Alamos National Laboratory.  Bees were […]

ID Support from Unlikely Quarters
November 27, 2006
While Nature 11/24 described intelligent design (ID) as a threat to science, support for it came from two new scientific books reviewed in the same issue.  Both of them, while not using the phrase intelligent design, deal with concepts that imply science must reach beyond material causes. Just right universal soup:  Jim Al-Khalili (U of […]

It’s Hard to Break a Bone
November 14, 2006
People wearing a cast right now may not feel comfortable, but should be thankful it’s hard to break a bone.  Scientists at Max Planck Institute discovered “a novel construction principle at the nanoscale which prevents bones from breaking at excessive force,” making them “nearly unbreakable.”  Because of the way the rigid components of bone tissue […]

You’ll Love Beetle-Foot Tape
November 6, 2006
If beetles can do it, scientists should be able to: climb the wall, that is.  Some researchers at Max Planck Institute have invented an adhesive that sticks to glass like beetle feet.  The secret was to manufacture thousands of microscopic pads that adhere to smooth surfaces by van der Waals forces (the attraction of neighboring […]

Self-cleaning Surfaces Take the Lotus Position
October 17, 2006
Photovoltaic cells and microelectromechanical systems have a problem: they collect dirt.  What to do?  Look to the lotus, says a EurekAlert article about research at Georgia Institute of Technology.  Dr. C. P. Wong and team took inspiration from the self-cleaning surfaces of lotus leaves.  “Despite growing in muddy conditions, the leaves and flowers remain clean […]

Whiskers Inspire Technology
October 4, 2006
The latest gadget on robots or Mars rovers could be whiskers.  These tactile sensors provide ways to see in 3D, says a report on National Geographic News.  Information about latitude, longitude and elevation can be gleaned from whiskers.  Rodents continually rotate their whiskers to gather information, but seals and sea lions let the ocean currents […]

Yoke Up Those Bacteria
September 6, 2006
My, how history repeats itself – often in unexpected ways.  In ancient times, our ancestors got the heavy work done by hitching oxen, horses or slaves (like Samson, see pictures 1 and 2) to a harness and making them turn a grinding wheel.  The same principle is now on the cutting edge of modern applied […]

Grass Shack Makes a Comeback
August 28, 2006
Oh, what a feeling: Toyota Roof Garden wants to replace your roof with grass.  Bill Christensen at Live Science says that the car company’s grass tiles include imbedded irrigation piping, provide good thermal insulation and reflect less urban heat to the atmosphere.  The special grass only needs mowing once a year.  Company website (Japanese): Toyota […]

Honey More Effective than Antibiotics
July 27, 2006
A good old nature remedy is making a comeback: honey for wounds.  An article on EurekAlert about research at the University of Bonn states that honey is more effective than antibiotics at healing cuts and wounds.  Apparently the ancient Egyptians knew about its healing power.  Honey rejects dead tissue faster, repels bacteria, promotes more rapid […]

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 […]
