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 […]

Are There Limits to Scientific Speculation?  A Royal Case

Question: When does science become like a priesthood?  Answer: When its practitioners engage in speculation on big questions impossible to verify with empirical observations.  Is this what the chief astronomer in Britain is doing?     Sir Martin Rees certainly would not have thought of himself as a priest as he wrote an article for […]

Scientist Sees Evolutionary Sense in Coordinated Complexity

An article on PhysOrg tells “A vertebrate story,” and a story it is: the more complex a phenomenon becomes, the more it makes evolutionary sense.     Portuguese scientists were studying the interaction of Hox genes with the development of the ribs in vertebrates.  You can imagine the control that these genes must have when […]

Southpaw Explanations Out of Left Field

All proteins are left handed.  Some humans are left handed.  Can evolution explain that?  Evolutionists are never known to be at a loss for words when asked to explain anything, provided they are allowed liberal use of the word perhaps.     A new projection theme for the first left-handed amino acids that comprise proteins […]

Clock Gene Same in Humans and Birds

Science Daily, this “not only sheds light on how our internal annual body clocks function but also shows a key link between birds and mammals that has been conserved over 300 million years.”     Mammals, including humans, have a hormone released by the pituitary gland that controls melatonin levels – known to affect the […]

Noah’s Ark on Mars

We apologize for this improbable headline to draw attention to two stories making the rounds: new claims about Noah’s Ark on Mt. Ararat, and new claims about life on Mars.  Headlines on these topics show up periodically in the news.  What do the subjects have in common?  How do they differ?  Do the most recent […]

New Theory on Evolution of Bat Flight

How did bats evolve the ability to fly?  Evolution helped them out by providing them with higher energy.  After all, “Flight is among the most energy-consuming activities” in the animal kingdom, said a team of Chinese and Canadian scientists reporting in PNAS,1 so it’s obvious that evolution must have provided the genes to get the […]

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 […]

What Can Fossil Leaf Measurements Tell About Evolution?

Flowering plants burst on the scene in the fossil record 140 million years ago in the geologic timescale, creating an “abominable mystery” for Charles Darwin.  What can be learned by measuring the stems and leaves of fossil specimens?     Dana Royer and colleagues from Wesleyan University in Connecticut embarked on a project to measure […]

Maxwell’s Demon Helps Run Your Muscles

James Clerk Maxwell once speculated that the second law of thermodynamics could be violated if an agent or “demon” could sort the hot and cold molecules at a barrier, thus overcoming the tendency toward thermal equilibrium.  Something like this has been found at work in the molecular machines in our muscles.  The actin-myosin motor is […]

Genetic Subcode Discovered

Computer programmers know all about subroutines.  One master program can easily call other programs, which can return results back to the master program.  That’s very 1960s.  Today’s modular software responds dynamically from disparate sources and responds to feedback from embedded triggers.  They can call routines written in other codes or languages.  We’re beginning to find […]

Psychologists Portray I.D. as a Form of Evolution

No need to draw a line between design and evolution, say two psychologists at the University of Iowa.  Intelligent design is really a lot like evolution.  They think we need to “better appreciate the actual forces that unite the processes of change across both evolutionary and developmental timescales.”     This strange theory was announced […]

Darwin as Canary in a Coal Mine

The state of evolution teaching is like the fabled canary in a coal mine, Sean Carroll told Science.1  That’s why the molecular biologist from the University of Wisconsin, Madison is cutting back on his research and undergraduate teaching to concentrate on his new appointment: vice president for science education at the Howard Hughes Medical Institute.  […]

SETI and other Pointless Gimmicks

Astrobiologist Paul Davies sure knows how to ask interesting questions, and ruffle feathers in the process.  His new book about SETI, The Eerie Silence, reviewed by Leslie Mullen in Astrobiology Magazine, defaced some long-standing notions.  But are his suggestions any improvement?     Davies thinks the Voyager record was a “pointless gimmick.”  He thinks that […]

Life, an Elegantly Simple Mistake

The ribosome is a complex molecular machine made up of multiple protein and RNA parts.  Last year, winners of the Nobel Prize in Chemistry (see 10/10/2009) were praised for elucidating the structure and activity of ribosomes.  News stories described “the whole complicated process of transcription initiation, an operation that is of crucial importance in all […]
