Butterfly Wing Veins Are Not in Vain

Inventors made an artificial butterfly modeled on the tiger swallowtail.  First they made the wing without veins.  It didn’t fly as well as when they added veins like the real butterfly, according to a short video clip in an article on New Scientist.  The veined wing provided more lift.     The inventors at Harvard’s […]

Venter Group Plagiarizes Genetic Code

Is plagiarism a form of intelligent design?  We think of intelligent design in terms of God and creation, but in generic terms, I.D. only refers to purposeful, designed action by an agent – any agent, large or small, good or evil.  A planned murder, for instance, can be an evil form of intelligent design.  A […]

Like Magic: Spiders Convert Fluid to Steel-Strong Silk

How do they do it?  Spiders spin their webs with such ease, but scientists know they are working a kind of material magic.  Inside the storage sac, the proteins act like a fluid.  Outside the spinnerets, that fluid turns into a structural rope that is stronger than steel, but elastic enough to absorb the energy […]

If Humans Build DNA Machines, Is It Intelligent Design?

Two teams have succeeded in building little robots that work on DNA tracks.  These resemble in many respects the machines that cells use to perform its functions on DNA.  No one denies that humans engineered their nanobots on purpose, but Darwinist scientists claim natural cellular machines evolved without purpose or design.  What’s the difference?   […]

Bacteria: Let’s Harness Those “Perfect Machines”

Ten Italian scientists have a novel idea.  They want to hitch up their wagons to bacteria and use them to power nanomachines.  It’s too much work to build such “perfect machines” from scratch, they said.  Why not just take advantage of what nature has already provided?     Their paper in PNAS1 is downright dreamy […]

Archer Fish Sees Clearly Up and Down

The archer fish, which lives in mangrove swamps and rivers, is able to spit insects off leaves above the water with remarkable accuracy (09/30/2002, 09/07/2004, 10/10/2006).  Scientists have been fascinated by this ability because in order for the fish to calculate the trajectory of its missiles, it needs to take into account both chromatic aberration […]

Blood Clotting Fibers May Lead to Better Networks

We all know that blood clotting has kept us alive many times.  We would never have survived childhood scrapes and cuts had it not been for a cascade of responses in blood that builds a network of fibers quickly upon which a scab of tissue stops the flow of blood and begins repairs.  That first […]

Blind Fish Lead the Blind

Imagine miniature subs that can negotiate tight spaces or murky waters in the dark.  Meet Snookie: a device created by researchers at the University of Technology Munich, who took their inspiration from blind cave fish.     The report on Live Science says that the blind Mexican cave fish Astyanax mexicanus is born with eyes […]

Biomimetics: Science for Now

Do you want science that makes a difference in our lives?  Look at real plants and animals with real solutions to practical problems.  That’s where researchers are making amazing discoveries with practical spinoffs. Shellfish materials:  Strong, lightweight structures are coming, thanks to the imitation of oysters and shellfish.  PhysOrg reported that researchers at the University […]

Search for Intraterrestrial Life Scores Big

Single-celled organisms may be tiny, but what they lack in bulk they make up for in volume and importance.  Scientists have been appreciating more than ever the ubiquitous presence of microbes on our planet and the roles they play to sustain the biosphere.     PhysOrg reported that half of the world’s life may lie […]

Life Leads the Way to Invention

Here’s a factoid for the party: a cell is 10,000 times more energy-efficient than a transistor.  PhysOrg tells us that “ In one second, a cell performs about 10 million energy-consuming chemical reactions, which altogether require about one picowatt (one millionth millionth of a watt) of power.”  This and other amazing facts lead to an […]

Spider Hair: The Perfect Water Repellant Surface

To keep dry, make like a spider.  “Engineering researchers have crafted a flat surface that refuses to get wet,” began a press release from University of Florida.  “Water droplets skitter across it like ball bearings tossed on ice.  The inspiration?  Not wax.  Not glass.  Not even Teflon.”  The audience waits breathlessly for the answer.  “Instead, […]

The Brain You Use, and How It Uses You

Neuroscientists continue to find out amazing things about the human brain.  In some ways we are responsible to use our brains, but in other ways the brain does things to us.  If nobody has figured out where the dividing line is for thousands of years, it’s unlikely we will today; but the following findings can […]

Life Masters Physics

Living things, especially cells, have mastered the forces of advanced physics in ingenious ways.  This ingenuity sometimes inspires physicists to try to copy it.  Here are some recent examples: Photosynthesis and quantum mechanics:  Nature reported that plants take advantage of quantum mechanics in photosynthesis.1  “The photosynthetic apparatus of cryptophyte algae is odd – its pigments […]

Spider Webs Are Precision Dew Collectors

Photographs of dew drops on spider webs are favorite targets for nature photographers, because they resemble strings of pearls on fine jewelry (example 1, example 2).  But did you know the reason dewdrops bead up so well on webs is due to the fine microstructure of the spider silk?  A team of Chinese scientists studied […]
