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 […]

Rubisco “Highly Tuned” for Fixing Atmospheric Carbon

June 22, 2006

Rubisco sounds like a brand of cracker or something, but it’s actually an air cleaner your life depends on. It’s an enzyme that fixes atmospheric carbon for use by photosynthetic microbes and plants. In doing so, it sweeps the planet of excess carbon dioxide – the greenhouse gas implicated in discussions of global warming – […]

Reach Out and Touch Some Robot

June 13, 2006

The news media were excited to report an advance in materials science last week that could pave the way for touchy-feely robots (see BBC News, News @ Nature, LiveScience and National Geographic News, for instance). Two scientists produced a thin film with touch resolution comparable to that of a human finger, an order of magnitude […]

Foot Facts: Frogs and Flies Fulfill Feet Feats

June 13, 2006

How do frogs walk on wet leaves without slipping? Eric Jaffe in Science News1 describes how they have dual-purpose footwear: a mucous film that holds on by wet adhesion, plus microscopic bumps that protrude above the wet layer to make dry contact. Though a frog foot doesn’t appear as fancy as that of a gecko, […]

Can the Origin of Life Be Simplified?

June 12, 2006

Evolutionists looking for a materialistic explanation for the origin of life know that there is a huge gap between a sea of chemicals and a self-replicating cell. Over the years since the Miller experiment (see 05/02/2003 entry), there have been several approaches trying to bridge this gap. One has been the RNA World hypothesis, that […]

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 […]

Beavers Achieve Environmental Reprieve

June 8, 2006

In what might be considered an unexpected convergence between geology and zoology, it has been found that beaver dams influence large tracts of land both above and below ground. “Impact of beaver dams wider than thought” announced a headline on LiveScience summarizing studies by scientists in Rocky Mountain National Park. The dams take […]

Protein Dressing Room Has Electronic Walls

June 7, 2006

Properly folded proteins are essential to all of life. When a polypeptide, or chain of amino acids, emerges from the ribosome translation factory on its way to becoming a protein, it looks like a useless, shapeless piece of string. It cannot perform its function till folded into a precise, compact shape particular for its job. […]

Hummingbirds: Small Wonders

June 5, 2006

Do you enjoy watching the world’s smallest birds, right from your backyard? Susan Healy and T. Andrew Hurly provided interesting tidbits about them in a Quick Guide to Hummingbirds in Current Biology this week.1 There are 330 species of these small flyers noted for their aerobatics and iridescent colors. Typically, they weigh a […]

Stupid Evolution Quote of the Week: Handy Dandy Modus Operandi

June 2, 2006

Charles G. Gross and Asif A. Ghazanfar win the prize for this gem in Science1 from a book review of The Sensory Hand by Vernon B. Mountcastle (Harvard, 2006): In one of the first systematic attempts to describe the differences between primates and other mammals, Thomas Huxley argued that the former are distinguished by virtue […]

Fitness Costs What? Say That Again?

May 9, 2006

Good news: evolution has figured out how to make your wounds heal faster. Bad news: the required mutation makes you go deaf. Believe it or not, that is the story told on News@Nature. “Deafness gene has health benefit,” wrote Alison Abbott. “Protein from genetic mutation helps wounds to heal.” The article treats this […]

Q: Who Fights With Supercharged Harpoons? A: Jellyfish

May 8, 2006

Weak, transparent, limp, and drifting in the water – who would have thought these creatures possess one of the most powerful weapons in the animal kingdom? Jellyfish and hydras have stinging cells called nematocysts that fire so fast, no one has been able to catch the action of their microscopic harpoons – till now. […]

The Evolution of Slapstick

May 2, 2006

Some Darwinists think they have figured out the origin of laughter. When our ape-like ancestors started walking, they found it awkward and often tripped over their feet. Bystanding apes apparently found this humorous for some reason, and thus slapstick comedy was born. The Times Online found this story good for some one-liners. How can this […]

What Use Is Half a Wing?

May 1, 2006

Ken Dial is at it again, trying to explain bird flight from the ground up with his own version of a Darwinian story (see 01/16/2003). The title of his paper in BioScience1 harks back to an old criticism of Darwin’s theory: “What use is half a wing?” Well, half a wing could be a half […]

Stupid Evolution Quote of the Week: Astrobiology Takes on I.D.

April 26, 2006

The Center for Astrobiology at the University of Boulder is hosting a symposium today entitled, “Fossils and Genes: Exploring the Evolution of Life.” Douglas Futuyma (State University of New York) calls Evolution the “most important theory in biology.” By his own admission, though, it is a theory filled with paradoxes: Evolution is both a fact […]
