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 […]

Dinosaurs Evolved from Birds

Birds evolved from dinosaurs, we are often told.  That’s backwards, reply some scientists at Oregon State University.  According to PhysOrg, the recently-published bi-plane model study of Microraptor gui (01/29/2010) demonstrates that theropod dinosaurs did not sprout wings and fly; instead, they became flightless after their bird ancestors came down from the trees.     Their […]

The Evolution of Religion – or Vice Versa?

A Harvard professor has evolutionized religion again.  Marc Hauser, the one who trains his little boy to adore Darwin (07/03/2007) and wrote a book on how natural selection created morality (10/27/2006), is now saying that religion is a by-product of our evolution.  “These findings suggest that religion evolved from pre-existing cognitive functions,” he wrote in […]

Small Hobbit Brain Means Little

Central in the debate whether Homo floresiensis (nicknamed hobbits) were human is the matter of their small brains.  Could diminutive human-like skeletons really be human with such small skulls? (cf. 03/04/2005).     Scientists at the University of Cambridge conducted a detailed analysis of brain size vs. body size for a number of primates.  They […]

Old Primordial Soup Is Spoiled

Don’t open it; that can of primordial soup sitting on the shelf for decades is rotten. PhysOrg announced, “New research rejects 80-year theory of ‘primordial soup’ as the origin of life.” In its place come new theories about tiny chemical cooking pots in the pores of deep-sea vents. Pioneered by Michael Russell (02/15/2008) and others, […]

Building a Cell: Staggering Complexity

“The living cell is a self-organizing, self-replicating, environmentally responsive machine of staggering complexity.”  Thus began a special section on “Building a Cell” in Nature last week.1  The section with five papers explores what is known about gene regulation, cell organization and signalling.  It’s an opportunity, as well, to see what scientists think about what they […]

SETI, Miracles, and Comfort

Would knowledge that the universe is filled with aliens bring you comfort?  Or are you more comfortable thinking humans are alone in the universe?  Seth Shostak, director of the SETI Institute, was interviewed briefly by Bill Hemmer on Fox News this morning, where only one answer to this idea was assumed.     Shostak came […]

Scientists Divine Deep Time in Dead Fish

Scientific experiments can certainly take on a wide variety of methods, from recreating the atmosphere of Titan to testing a drug on a genetic disease.  But if educators want to encourage students to become scientists, they had best keep silent about “some very unpleasant experiments” at the University of Leicester reported by the BBC News.  […]

Incredible Creatures that Support Evolution?

Paleontologists and biologists continue to uncover animals past and present that exhibit amazing diversity. Some of them are so weird and unexpected, they are almost unbelievable. Usually, the news media are quick to tally up points for Darwin by explaining to lay people how they shed light on evolution. But in the “discovery” stage of […]

Woese Slays Darwin

The king is dead!  Long live the king!  Such were the oxymoronic cries of olden times when royal succession took place.  Has Charles Darwin been dethroned?  One would think so, after reading Mark Buchanan’s article, “Horizontal and vertical: the evolution of evolution” in New Scientist.  Buchanan sets the stage: Just suppose that Darwin’s ideas were […]

Barefoot Is Better

Who do we wear shoes?  It seems obvious; we expect that they help us avoid injuries and provide comfort.  Maybe we should think of the injuries we are getting by wearing them.     The image of the barefoot person is usually of someone poor, deprived, lower-class, hick, unclean, redneck or something else unattractive.  Shoes […]

Convergence: Explanation or Rescue Device?

The news media are telling us that bats and dolphins both hit on the same genetic pathway to evolve echolocation – even though they are on vastly different evolutionary lineages and use echolocation differently (one in air, one in water).  Since it is inconceivable that a putative shrew-like common ancestor of these very different animals […]

Aliens Invade Science News

What are aliens doing in science news reports?  There is no evidence they even exist.  That has not hindered some scientists from speculating.  BBC News reporters Pallab Ghosh headlined an entry “Astronomers hopeful of detecting extra-terrestrial life,” and adorned it with a Hollywood-style alien corpse.  The article highlighted the optimism of Lord Rees, the president […]

Fermi Paradox Reasserts Itself

Paul Davies, no stranger to facing difficult questions and proposing imaginative solutions, is coming out with a new book in April about SETI.  In it, he tackles the Fermi Paradox: if aliens are out there, why haven’t they dropped by yet?  Amazon.com lists some of the ideas to be presented in The Eerie Silence: Renewing […]

Evolutionary Biogeography Requires Imagination

Biogeography – the study of the distribution of species – has been an important part of evolutionary theory, and has often been used as evidence for evolution.  Some recent findings about plants and animals should give scientists caution about trying to divine too much evolutionary history from locations of present-day organisms and fossils.     […]
