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 […]

Cells Use Cloud Computing
June 19, 2009
“Cloud computing” is the up-and-coming trend in information technology.  It allows processes to run in parallel on multiple networked processors with more robustness, because other processors can pick up the slack if a major server fails.  Scientists are finding that cells have been using this technology all along.     Science Daily reported on work […]

What Makes You Human?
June 17, 2009
If you are a war-mongering beast who likes to burn things, you’re displaying your evolutionary past.  That’s what a couple of news reports are claiming.  New Scientist has a review of two books: Fire: The spark that ignited human evolution by Frances D. Burton, and Catching Fire: How cooking made us human by Richard Wrangham.  […]

Plants Use the Perfect Propeller
June 16, 2009
What kid hasn’t played with maple seeds to watch them spin in the air like helicopters?  Scientists watch them, too.  A team from the Netherlands and California found out how they stay in the air for so long without engines to drive them.  One would think in an era of advanced aeronautical engineering the physics […]

Fighter Jet of the Animal World
June 10, 2009
A male hummingbird in its aerial display achieves speeds proportionally faster than a jet fighter with its afterburners on, reported the BBC News – and that’s on nectar and wings, without jet fuel.  The tiny birds even resemble top-gun fighter jets in the pictures accompanying the article.     It took a camera shooting 500 […]

Tickle Me Darwin
June 8, 2009
Observation: orangutans seem to laugh when tickled.  Conclusion: humans evolved laughter from our ape past.  This is the story being promoted by the science news outlets.  “At least 10 million years ago, our ancestors may have been laughing it up over the latest stone-age prank or bout of tickling,” announced Live Science.     New […]

Bees’ Knees Bridle the Breeze
June 5, 2009
Bees stabilize their flight in windy conditions by extending their hind legs.  Even though this costs 30% more energy and produces more drag, it provides stabilization against turbulence by increasing their moment of inertia (i.e., their resistance to being flipped over).     A team of scientists videotaped the insects flying when blasted by powerful […]

Grasses Ratchet Their Seeds Into Distance Travelers
June 2, 2009
John Muir said we should not pity plants as prisoners to one spot.  In their own ways, they travel the world as we humans do.  Anyone who has walked through wild dry grass may have been annoyed at how many foxtails get buried in their socks and how hard it is to get them out.  […]

Protein Springs Keep Crabs Happy
June 1, 2009
Crabs and crayfish contain “exquisite” protein springs around their mouth parts that enhance motion, signaling, and sensing of their environment, Science Daily reported, about work done at the University of Cambridge.     The protein involved, called resilin, is almost perfectly elastic.  “The exquisite rubbery properties of resilin are known to be put to use […]

Another Crow Species Impresses Scientists with Tool-Making Skills
May 26, 2009
Who would have thought that crows rival chimpanzees in intelligence?  Members of the corvid group, which includes crows and ravens, are amazing researchers with their ability to make tools.     Previous studies with New Caledonian crows (08/09/2002, 10/07/2007, 02/23/2007) impressed researchers with the birds’ abilities to fashion simple tools out of available materials to […]
