Fast Protein Fine-Tunes the Ear
February 13, 2008
Remember prestin?  It’s a motor protein in the inner ear, discovered in 2001 (03/27/2001), that acts so fast – within millionths of a second – its discoverers named it after the word “presto!” (02/21/2002).  Scientists have been studying its role as a volume adjuster (07/31/2007) that allows it to amplify sound 10,000-fold (09/19/2002) .  New […]

Migrating Birds Measure Longitude
February 13, 2008
Migrating birds are able to get back on course, even when released 1000 km east of their normal migration path.  This shows that long-distance migrating birds are capable of true bicoordinate navigation: the ability to make course corrections both in latitude and longitude.  The results of experiments, published in Current Biology,1 left the researchers baffled: […]

Did Birds Evolve Aeronautical Engineering?
February 8, 2008
Two news stories on birds may not seem to flock together.  One is about their supreme aeronautical engineering.  The other ponders when they evolved.     A story on EurekAlert and Science Daily describes how engineers are eyeing birds, bats and insects for design ideas.  The appeal is clear from the following comparisons: A Blackbird […]

Nose Code Rockets Smell Discrimination
February 1, 2008
You have a code in your nose.  Scientists working on fruit fly olfactory systems have found that a mapping mechanism between components maximizes the fly’s ability to discriminate smells.  The coding system provides a non-linear response that appears finely tuned to maximize the information content of odor inputs.     The components of this system […]

Quality Control Ensures Accurate Cell Division
December 28, 2007
Cell division (mitosis) is a very complex process in which every part must be accurately duplicated and sent to the proper destination.  Picture a marching band where each flute player or tuba player is able to clone itself.  The players congregate at the center in two lines, divide, and move apart, forming two marching bands […]

DNA Translation Has Codes Upon Codes
December 17, 2007
The DNA code is protected by another code, and is read with a machine that reads a third code.  This is an emerging picture from ongoing research into DNA transcription, as reported in Science.1     In the 1950s, scientists were astonished to find a code at the genetic basis of life.  DNA’s four-letter alphabet, […]

Geology Sinks in the Mud
December 14, 2007
Question: what is the most abundant sedimentary rock in the world?  Follow-up question: what would happen to the science of geology if the consensus theory of how this most abundant sedimentary rock was deposited turns out to be wrong?  Prepare for a paradigm shift: experiments have shown mistakes in long-held assumptions about mudstone formation. Here’s […]
