How to Call Your Opponent Stupid Using Evolution
February 27, 2010
It may be that Professor Kanazawa was intending to be compassionate by couching his assessment in the language of evolutionary theory, but he essentially made a categorical judgment that conservatives and Christians are stupid, and atheists and the sexually promiscuous are smart. How could he say such a thing? He could dodge the charge of […]
Making Evolution Simple
February 25, 2010
Getting the vast diversity of highly complex creatures seems an impossible task for evolutionary theory, but some recent stories claim it’s not so hard. Beak of the finch: Darwin’s finches keep pecking their way into the media. A new study claims that the wide diversity of beak shapes that have evolved can be explained by […]
Spider Hair: The Perfect Water Repellant Surface
February 24, 2010
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, […]
Multiverse Explanations Are Fashionable, If Not Justifiable
February 22, 2010
How can scientists get away with speculating about unobservable universes, when science is supposed to concern itself with observation? “In the end, there is no way to know for sure what other universes are out there, or what life they may hold,” an article in PhysOrg ended, “But that will likely not stop physicists from […]
The Brain You Use, and How It Uses You
February 21, 2010
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 […]
Molecular Highway Motor Comes into Focus
February 19, 2010
A beautiful new image of kinesin, a molecular machine that carries cargo on cellular highways, has been produced in greater detail than ever by a team at Berkeley and Brandeis Universities. Science Daily published a picture and description of how kinesin works. “Life’s smallest motor – a protein that shuttles cargo within cells and helps […]
Who Should Be Listening to Scientists?
February 17, 2010
“Stop Listening to Scientists?” is an unusual title for a letter to Science.1 In a commentary last week prompted by the recent scandals regarding climate change, Kevin Robert Gurney (Purdue) made a shocking exclamation: don’t listen to scientists. Here’s how he began. As a climate scientist and a contributing author to the Intergovernmental Panel on […]
Life Is Smarter Than We Know
February 15, 2010
How can toads calculate? How can cells without a brain or central nervous system figure out a balanced diet? How can bugs navigate the wind for optimum flight time? These are some of the questions that can arise from observations of the living world. The more we learn about life, the more we find unexpected […]
Life Masters Physics
February 10, 2010
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 […]
The Evolution of Religion or Vice Versa?
February 8, 2010
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 […]
Spider Webs Are Precision Dew Collectors
February 4, 2010
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 […]
Building a Cell: Staggering Complexity
February 2, 2010
“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 […]
Scientists Divine Deep Time in Dead Fish
January 30, 2010
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. […]
Woese Slays Darwin
January 28, 2010
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 […]
