Cell Motors Play Together

If one molecular machine by itself is a wonder, what would you think of groups of them playing in concert?  Recent papers and news articles are claiming that’s what happens in living cells: molecular motors coordinate their efforts.     Science Daily led off a story on this by saying, “Even within cells, the left […]

Assassins Roam Our Highways

Slinking surreptitiously through our blood streams, the assassins prowl about, looking for their targets.  These are not terrorists or vigilantes.  They have a license to kill.  Be glad they are there; they have saved your life many times.  They are called natural killer cells.     PhysOrg reported on work going on at Howard Hughes […]

Songbirds Sing on a Fast Wing

Purple martins and wood thrushes are common songbirds of the eastern United States.  Until recently, it has not been possible to follow their movements accurately.  Now, a team of biologists in Toronto, Erie and Cambridge was able to track them with tiny geolocators.  They found that the little birds fly farther and faster than previously […]

The Uses of Wood Rot

Wood rot fungus doesn’t sound like a useful thing.  Most people would rather get rid of it – especially those who have seen their houses decay because of it.  Some scientists, however, are intrigued by it.  It may have properties that could some day help power your car.     Science Daily reported that the […]

Modeling Solar Cells on Butterflies

Sunlight is free – if we could just learn how to use it better.  For decades, engineers have been trying to improve the efficiency of solar cells.  Why not look at nature?  Science Daily reported on work going on in China and Japan: “The discovery that butterfly wings have scales that act as tiny solar […]

Evolution as Efficiency Expert

Who would have thought that a lowly bacterium is a “master of industrial efficiency”?  That’s what a researcher at the Weizmann Institute of Science called it.  E. coli, the best-studied microbe, “can be thought of as a factory with just one product: itself,” a press release said.  “It exists to make copies of itself, and […]

Corn Is Fuel in More Ways than One

There’s been controversy lately about the diversion of corn crops from food for humans to ethanol for engines.  Why not both?  A new pilot program announced by Fraunhofer-Gesellschaft saves the corn cobs for eating but makes ethanol out of the straw.  If so, this would make the whole plant an energy factory for the human […]

Biology Now Includes Fluid Dynamic Construction

There’s an old legend that Tibetan monks built a wall by levitating heavy stones with sound by beating their drums and gongs.  Something not quite so fantastic but still amazing is done by cells in the embryo.  Scientists have filmed zebrafish embryos using beating cilia to build little stone structures that they use for balance. […]

Watch for Flying Giraffes (and Convergent Evolutionists)

Imagine giraffe-sized animals that could fly.  They lived.  National Geographic News has an illustration of an extinct pterosaur, tall as a giraffe, that was able to leap into the air and flap its wings for sustained powered flight.     Live Science discussed work by Michael Habib [Johns Hopkins U School of Medicine] on the […]

Your Brain Decides Best Unconsciously

A report on Science Daily claims your subconscious brain makes the best decisions possible.  This is based on work by cognitive neuroscientists at the University of Rochester.  Alex Pouget believes the brain is hard-wired to make optimal decisions – when we are not consciously thinking about them. Pouget has been demonstrating for years that certain […]

Handy Motor Found in Virus

Your job today is to stuff a delicate chain into a barrel without breaking it and make it wrap neatly inside.  A tiny virus does this with helping hands, reported Purdue University.  A research team uncovered the mechanism of a “powerful molecular motor” that crams the viral DNA tightly into the capsid with the help […]

Plants Heal Humans and Vice Versa

Flowers in your hospital room do actually make you heal faster.  A study by Kansas State researchers reported by PhysOrg found that more patients recovered from abdominal surgery faster with flowers in the room.  It may be due to more than the psychological benefit of enjoying their colors, fragrances and the get-well wishes behind them: […]

Cilium Likened to GPS

A story on Science Daily says that the primary cilium, a protrusion on most human cells that looks like an antenna, acts like a GPS system.  They “orient cells to move in the right direction and at the speed needed to heal wounds, much like a Global Positioning System helps ships navigate to their destinations.” […]

Fish and Reptiles Converge on Magnetic Navigation

Two very different kinds of animal both have outstanding ability to navigate by earth’s magnetic field: salmon and sea turtles.  A new hypothesis by scientists at University of North Carolina at Chapel Hill, published in PNAS,1 suggests that the young are “imprinted” with their local magnetic field signature at birth. From a navigational perspective, some […]

Fly Swiftly

The common swift is being eyed by aircraft engineers who want to go fast, high, and green.  Science Daily says these engineers are “inspired by nature.”     Calling Apus apus a common “swift” is like calling an orange an orange.  They are swift!  These incredible birds dart about effortlessly and spend their lives almost […]
