Seeking Explanations for Plant Fibonacci Spirals
May 6, 2007
The spiral patterns on an artichoke are enough to make a physicist choke.  How do plants like cacti, sunflowers, strawberries and artichokes produce geometric patterns of left- and right- handed spirals?  Why do these spirals follow a mathematical rule called the Fibonacci sequence?  A new theory suggests that it is the optimal energy arrangement for […]

Update on Plant Communication
April 26, 2007
Plants have both an intranet and an extranet.  Some recent papers investigated further about how plants, though rooted in the ground, keep in touch with the inside and outside economy. Intranet:  In 2001 (07/13/2001), and periodically since (10/04/2004, 11/09/2004) we reported the current thinking about how a plant knows when to flower, and described a […]

Orchid Deception: Is It Evolution?
February 26, 2007
Orchids comprise the most exotic and diverse group of flowering plants.  Some 30,000 species strong, this group contains members with unusual sex organs.  Some have organs that look and smell like the female of the insect species that pollinate them.  They seduce the males without giving them a reward of nectar for their stopover.  How […]

In Science and Politics, Expect the Unexpected
December 29, 2006
Two findings reported this month illustrate how science changes.  Paradigms and policies can have their scientific underpinnings yanked out from under them, causing both consternation and opportunities for new ways of thinking. Bring back the acid rain:  Pick your poison: acid rain or global warming.  Acid rain was the bogeyman of the 1980s, leading to […]

Plant Pores March to Their Own Beat
December 22, 2006
Plants have pores called stomata that open and close (see 09/13/2006).  These gates of the leaf surface provide plant protection from invaders, and allow the transpiration of gases and water vapor in and out, depending on conditions.  The stomata of many plants open wide during the day to allow in carbon dioxide, but close at […]

Plants Have an Immune System, Too
November 26, 2006
We know that animals fight disease with an army of patrols swimming in blood, but how do plants cope?  They are exposed to pathogens, too: everything from bacteria to fungi, worms and insects.  Without a central nervous system or circulatory system to help, are our gentle green friends at the mercy of what comes?  The […]

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 […]

What’s Inside a Spore?  Nanotechnology
September 17, 2006
The spores that are emitted from fungi and ferns are so tiny, the appear like dust in the wind.  Who would have ever thought such specks could exhibit nano-technological wonders like scientists have found recently: Evapo-Motors:  Scientists at U of Michigan were intrigued by how ferns turn the power of evaporation into launching pads.  The […]

Plant Protection: A Modern Medieval Castle Story
September 13, 2006
Vigilant guards stand at the gates.  In times of peace, they let down the drawbridge, and the townspeople carry on their trade.  Farmers bring in their crops for the marketplace, and local craftsmen and pedlars keep the local economy bustling.  Yet the sentries maintain a watchful eye, aware that numerous interlopers are about.  Aliens constantly […]

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 […]

Darwin’s Yard De-Evolves
July 21, 2006
According to the BBC News biodiversity in Darwin’s yard at Down House in England has declined 15% since he fastidiously catalogued plant species there in 1855. This story signifies nothing significant.  Biodiversity naturally declines in some grasslands as forests encroach and a climax community develops.  Evolutionists would not expect noteworthy genetic change in just 150 […]

Plants Use Electrical Sunscreen
June 23, 2006
Perhaps only a scientist, or a kid, would worry about how a plant doesn’t get sunburn, but it took elaborate scientific work for six months to find the answer.  EurekAlert told about research at the Biodesign Institute at Arizona State that found how plants get rid of excess solar energy.  They use carotenoids, molecules responsible […]

Plant Hula-Hoop Railroads Build Cell Walls
June 9, 2006
Solving a long-standing mystery about how plants build cell walls, Stanford scientists imaged molecular machines traveling along hoop-shaped rings around the inside of the cell.  Publishing in Science, Paradez, Somerville and Ehrhardt proved that cellulose synthase (CESA), a machine that manufactures cellulose composed of six subunits arranged in rosettes, rides like a rail car on […]

Cactus Evolution Explained
May 12, 2006
Phew, finally: now we know how cacti evolved, reports EurekAlert.  Ouch!  On second thought, how’s that again?     Two Yale scientists set out to figure out how the succulent plants turned leaves into spines.  Using molecular methods, they identified the earliest cactus, but then said it “already showed water use patterns that are similar […]
