Accurate Chemical Classifier Mimics Insect Nose

Two Germans have built a better chemical classification system by taking their inspiration from insect olfactory organs.  Here’s how they described their achievement in an abstract from PNAS:1 The chemical sense of insects has evolved to encode and classify odorants.  Thus, the neural circuits in their olfactory system are likely to implement an efficient method […]

Will Adult Stem Cells Cure Sickle Cell Anemia?

It’s been just weeks since two labs announced success harvesting pluripotent stem cells from skin cells (11/20/2007), and already beneficial applications are in sight.  Science Daily and Live Science reported on initial tests that show the new “induced pluripotent stem cells” offer hope for millions afflicted with sickle-cell anemia.  Though it’s too early to tell […]

What Keeps Skin Strong? Velcro!

Skin would fall to pieces were it not for velcro-like molecules that bind its cells together.  These molecules, called cadherins, make skin strong but also supple.  Their secret was explained by Ashraf Al-Amoudi of the European Molecular Biology Laboratory, quoted in Live Science.  “The trick is that each cadherin binds twice: once to a molecule […]

SETI: Physics Conspires to Keep the Aliens Isolated

Where are the aliens?  They’re too far away to get to know.  Don’t look for galactic federations to join any time soon, said SETI Institute Director Seth Shostak at Space.com.  The harsh realities of the speed of light make fellowship, both in person and via radio signals, too remote to be feasible.     Shostak […]

Origin of Life: Food for Queazy Thought

New theories of the origin of life seem to come and go like fashion trends.  A biochemist at University of California at Santa Barbara (Helen Hansma) put out a new plot line about biomolecules forming between the protective flakes of mica.  This was all Dave Mosher at Live Science (see reprint on MSNBC) needed to […]

Is Making Planets Child’s Play?

Are star children good at child's play? Like making mudballs, it should be easy to roll up dust into planets.

Evolutionists Explain Living Fossils

Here’s an old “evolutionary puzzle” to challenge your local Darwinist: explain living fossils.  Many living animals and plants were known only from the fossil record, thought to have gone extinct many millions of years ago, only to turn up in a local meat market or remote forest.  Science Daily tackled this question in the Nov. […]

Active Moons Challenge Old-Age Beliefs

Beyond the asteroid belt, where sunlight is weak, small bodies that should be old and cold seem young and active.  Here are some recent papers and reports about some of the moons around the gas giants showing more signs of vitality than expected for bodies assumed to be billions of years old. Jupiter’s Io: Astronomers […]

Hadrosaur Skin Flick

The press is abuzz with the story of a mummified hadrosaur found in North Dakota with skin and fossilized soft parts; see PhysOrg, Science Daily, Associated Press and BBC News.  Since the fully-articulated, uncollapsed, mummified fossil named “Dakota” was discovered in 1999, though, it appears that the announcement is being made now primarily as publicity […]

Cell Gatekeepers: Diverse, Complex, Accurate

Cargo moves around rapidly and ceaselessly in every cell.  Some moves in and out of the external membrane, and some moves in and out of organelles and the nucleus.  In a system of protected domains surrounded by impermeable membranes, how does the cell control what should pass?  Details of the amazing gatekeeping mechanisms embedded in […]

Wilson Duo Resurrects Darwin’s Taboo

Group selection (sociobiology) has long been a taboo subject, but now its time has come.  This is what an article on EurekAlert claims.  E. O. Wilson and David Sloan Wilson are on a new campaign to promote group selection.     The two Wilsons called for a new consensus on sociobiology in The Quarterly Review […]

Flowering Plants Do Big Bang in Darwin’s Face

There’s a big bang in botany.  The flowering plants, reported Science Daily, “evolved very quickly into five groups.”     The claim is based on the investigation of plant genes by scientists in Florida.  Their work “showed that a stunning diversification of flowering plants they are referring to as the ‘Big Bang’ took place in […]

New Dinosaur Finds Astonish Paleontologists

Some recent dinosaur discoveries on different sides of the world have produced amazement among scientists and the public as well. Tire tracks uncover dino tracks:  ATVs and dirt bikes have ridden for years over a place that is now found to be loaded with dinosaur tracks.  Near Coral Pink Sand Dunes State Park in Utah, […]

Who Knows the Age of Grand Canyon?

“In spite of over a century of work on the Grand Canyon, there are still fundamental questions about the age of the canyon and the processes that have formed it.”  Thus begins a paper in the November GSA Bulletin of the Geological Society of America.1  To re-evaluate the date of Grand Canyon, a team dated […]

Nehemiah’s Wall Found

Earlier this month, archaeologist Eilat Mazar found remnants of an ancient wall on the old city of David she believes is a remnant of the wall built by Nehemiah in 445 BC (see Nehemiah 3-6 that describes the project in detail).  This was reported on the Bible Places blog, with a link to The Trumpet […]
