The Trouble with Neanderthals
September 18, 2006
If nothing else, the scientific investigation of Neanderthal Man is valuable for illustrating how fluid scientific opinion can be.  Since we found out Sept. 1 that Neanderthal genes may be lurking among us, two more unexpected claims have been made about these wrestler-build members of genus Homo. Hideouts and Holdouts:  Some Neanderthals may have lived […]

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 […]

Voles Throw Evolutionary Genetics Into Disarray
September 16, 2006
What is it with voles?  These little gopher-like furballs with beady eyes, short tails and tiny ears are giving evolutionary geneticists fits.  A press release from Purdue University states, “Purdue University research has shown that the vole, a mouselike rodent, is not only the fastest evolving mammal, but also harbors a number of puzzling genetic […]

Record Dino Trove in Mongolia
September 15, 2006
67 dinosaurs in a week: that’s what diggers from Montana State University found in the Gobi Desert in Mongolia.  The team effort was led by veteran dinosaurologist Jack Horner.  Most skeletons were Psittacosaurs, thought to be predecessors of the horned ceratopsids, like Triceratops.  Seeking to understand the developmental biology of dinosaurs, the team was less […]

Ethane Cloud at Titan: Too Little, Too Late?
September 14, 2006
Those following the Titan exploration by Cassini-Huygens have wondered where the ethane went.  Oceans of ethane hundreds of meters deep, if not kilometers deep, were predicted but not found, as reported previously (see 04/25/2003 and 10/16/2003 pre-Huygens reports, 01/15/2005 and 01/21/2005 Huygens early results, and 12/05/2005 review; see also New Scientist analysis of the “total […]

Another Rotary Machine Found in Bacteria
September 13, 2006
A molecular “garbage disposer” in the cell membrane bearing some resemblance to the rotating motor ATP synthase has been described in Nature.1  This machine, called AcrB, expels toxins from the cytoplasm through the cell membrane to the outside.  Like ATP synthase, it has three active sites at one end where the binding occurs, and it […]

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 […]

Do Mammals Depend on Virus Help?
September 12, 2006
Researchers found that sheep depend on a retrovirus to become pregnant.  Retroviruses (those that can insert themselves into a genome of a host cell) include the dreaded HIV and generally have a bad reputation.  Remnant retroviruses are prevalent in many animal species and have been considered a class of “junk DNA,” having mutated away their […]

Patients in Vegetative State May Be Aware
September 11, 2006
Remember the arguments put forth for why Terry Schiavo should be allowed to die?  They revolved around the awareness of those said to be in a persistent vegetative state.  Now, researchers reported in Science1 that a patient diagnosed in a vegetative state was aware of what was going on: We used functional magnetic resonance imaging […]

Historian Reveals Isaac Newton as Biblical Economist
September 11, 2006
The image of Isaac Newton as pure mathematician and physicist ignores a big part of his persona, said Georgia Tech Professor Kenneth Knoespel in a press release reported by EurekAlert.  Living in an era when alchemy was still considered a serious subject for natural philosophers, Newton viewed alchemical research as part of his Biblical vision […]

Nature Backpedals Over Stem-Cell Hype
September 10, 2006
After Nature printed an upbeat press release last month that stem cells could be extracted without killing an embryo (see 08/25/2006), critics found that the experiment did indeed kill the embryos.  Also, it turns out none of the stem cell lines survived, and that more than one cell had been extracted from the embryos, contrary […]

Is the Fruit from Darwin’s Tree Edible?
September 8, 2006
Darwin’s “Tree of Life” fruit stand found an upbeat salesman in John Roach at National Geographic this week.  In his update on the “Assembling the Tree of Life” (AToL) project, he reported cheerfully that “New cures, supercrops, and secrets of evolution may emerge from the fast-growing branches of the ‘Tree of Life,’ scientists say.”   […]

Nothing in Evolution Makes Sense Except in the Light of Speculation
September 7, 2006
Welcome to an imaginary world of Red Queens, Green Beards and warring armies: the world of evolutionary theory.  Though its adherents work in prestigious universities and laboratories in the real world, they seem preoccupied with speculative visions of imaginative fitness landscapes – even when defending evolutionary theory as the best explanation for natural phenomena, and […]

Whistling in the Dark Matter Debate
September 7, 2006
Who’s right?  Douglas Clowe’s team at U of Arizona claimed two weeks ago that they found dark matter in the Bullet Cluster – they even had a picture of it.  The Chandra X-Ray Center called it “direct proof” of dark matter.  Two days later, EurekAlert posted a story about a new proposal to bring back […]
