Lotus Glass Repels Water, Dirt, Bacteria
September 23, 2009
Imagine never having to wash your windows again.  That would be a huge boon not only for window washers on skyscrapers, but for astronauts on the space shuttle or space station.  It may become a reality, thanks to the lotus plant.     Science Daily reported on work by a company in Atlanta that has […]

Nature’s Designs Are Engineers’ Finds
September 18, 2009
Nature is a treasure trove of technology.  Though engineers have garnered inspiration from nature since the Wright brothers and before, it seems that in recent years there has been a gold rush to follow nature’s lead. Wet glue:  Worms may not be very inspiring to most people, but Science News reported that scientists at the […]

Your Eye Sees Trouble Before You Do
September 10, 2009
In slapstick comedy, the fall guy gets the pie in the face when the clown in front of him ducks.  It’s funny because most of us instinctively duck when we see something coming.  But two recent experimental studies are revealing new automated capabilities built into the eye and brain that are quicker and more automatic […]

Molecular Machines on Parade
September 3, 2009
Scientific papers continue to exhibit the exquisite mechanisms in the cell for handling all kinds of situations, through the operation of molecular machines.  Here are a few recent examples from this week’s issue of Nature (Sept 3, 2009). Molecular sieve:  What happens when a cell gets bloated?  Too much water entering a cell can increase […]

Your Throat Has Tasteful Antennae
August 30, 2009
Our airways are lined with cells that have beating oars called motile cilia.  Like galley slaves on a Roman ship, they beat in coordinated waves, setting up currents that propel dust and foreign matter out toward the mouth.  Scientists just found out another amazing capability of these motile cilia: they can “taste” toxic chemicals and […]

Plants Use Hourglass Mechanism
August 26, 2009
Plants need to know when to flower and produce seed.  They can read the sunshine, but what about plants living in shade or cloudy conditions?  It turns out they have two mechanisms for telling time: a light meter and an hourglass.  If the light meter doesn’t switch on, the hourglass lets the plant know it […]

DNA Translator More Complicated Than Thought
August 24, 2009
One of the most remarkable molecular machines in your body, the ribosome, is coming to light, nanometer by nanometer, as scientists find new ways to peer into the inner workings of the “black box.”     Science Daily reported on work at Berkeley that has given the clearest imagery yet.  “Ribosomes, which number in the […]

Protein Function: It’s All in the Fold
August 11, 2009
Most chemical reactions involve atoms or molecules bumping into one another and exchanging electrons.  Proteins, by contrast, derive their immense functional repertoire from their shapes.  Several recent studies explore the amazing potential for strength, motility and catalysis that derives from the way proteins fold. Clots:  A picture of fibrin graces an article in Science Daily.  […]

Crow Fulfills Aesop Story
August 11, 2009
The fabled intelligence of the crow has been tested, and the crows passed.  Bird and Emery tested an old Aesop fable and were amazed: In Aesop’s fable The Crow and the Pitcher, a thirsty crow uses stones to raise the level of water in a pitcher and quench its thirst.  A number of corvids have […]

Systems Biology Oddly Silent About Darwin
July 21, 2009
Two papers on the rise of “systems biology” appeared in Nature last week.  Both are astounded by the complexity of the cell, but neither had anything to say about evolution, Darwin, or phylogeny – mildly surprising when the proponents of evolution keep saying that “nothing in biology makes sense except in the light of evolution.” […]

Dragonflies Are Marathon Champs
July 15, 2009
Step aside, monarch butterflies: some of your fellow insects beat your distance flying wings down.  The BBC News reported on findings by a biologist in the Maldives about dragonflies that migrate 14,000 to 18,000 km from southern India to East Africa and back – including 800 km over open sea.  How these insects can navigate […]

A Rat Race to Build Whiskered Robots
July 11, 2009
Some scientists at Bristol Robotics Lab are pretty proud of themselves for building a robot with whiskers.  It can seek out and identify objects using its whiskers, just like rats do.  But they should still take their hats off to their living model, because the rat’s technology is far superior.  Science Daily mentioned several facts […]

Warning: Do NOT Mutate This Protein Complex
June 30, 2009
In each cell of your body there is a complex of 8 or more proteins bound together called the BBSome.  This protein complex, discovered in 2007, should not be disturbed.  Here’s what happens when it mutates: “A homozygous mutation in any BBSome subunit (except BBIP10) will make you blind, obese and deaf, will obliterate your […]

How Cells Proofread DNA Is Still Mysterious
June 29, 2009
An amazing fact about DNA transcription is that the machinery not only copies DNA onto RNA, but checks it for errors.  A story in Science Daily says that researchers would expect 100 times more errors statistically than the actual results of transcription in the cell.     One of the mechanisms revealed in more detail […]

Computer Programmers Borrow Eye Technology
June 28, 2009
Computer processing of video images may become twice as accurate with 10 times the speed of earlier models, thanks to what scientists are imitating in the human eye.  “The linear solution to one of the most vexing challenges to advancing computer vision has direct applications in the fields of action and object recognition, surveillance, wide-base […]
