Love Your Planet
July 13, 2008
Modern astronomy and space travel have given humans the ability to view the earth from a distance and ponder its significance. Some astronomers expected the earth to be ordinary-looking. In many respects, however, astronomy is teaching us otherwise. Clara Moskowitz, staff writer for Space.com began an article by saying, “Earth is one special planet.” […]
What Mean These Stars?
July 12, 2008
There are more things in heaven and earth than are dreamt of in current astronomical models. Two articles recently underscored the fact that astronomers still have a lot to learn. Cluster generation conundrum: The members of globular star clusters were long thought to be old stars of the same age, like seniors at a care […]
Flatfish Evolution Revealed
July 11, 2008
Darwin has been vindicated again, to hear the media reports. Science Daily said, “Flatfish Fossils Fill in Evolutionary Missing Link.” National Geographic News ruled out the competition by saying, “Odd Fish Find Contradicts Intelligent Design Argument.” In a nutshell, Science Daily said, “Hidden away in museums for more that 100 years, some recently rediscovered flatfish […]
Why Academic Freedom Is Dangerous
July 10, 2008
Barbara Forrest has a tough case on her hands. The veteran creationist-fighter has to convince the people of Louisiana that they did a bad thing by passing the Academic Freedom Bill, because academic freedom when it comes to discussing intelligent design and evolution is dangerous (cf. 05/12/2008, bullet 3). The bill passed by 94-3 in […]
First Mercury Research Papers in from MESSENGER
July 9, 2008
Science published a suite of papers analyzing data from the first MESSENGER spacecraft flyby of Mercury.1 The flyby last January was the first since Mariner 10 visited in the 1970s. Mariner 10 had left many questions that are now being revisited. Among the dozen papers and articles, here are three that discuss the most significant […]
Feather Fossil Fallacy?
July 9, 2008
Imprints of melanocytes have been found in fossil feathers. What does this mean? The popular science news reports, like Science Daily, Live Science, PhysOrg and the BBC News seem convinced it can tell us something about how birds evolved from dinosaurs. Understanding what was discovered requires sifting through claims that go far beyond the evidence. […]
Its Networks All the Way Down
July 8, 2008
New ways of seeing biology are finding life is full of networks. At both ends of the complexity scale – from humans to bacteria – complex interactions are the rule. Two teams studying different phenomena had the same reaction – astonishment. Bottom-up complexity: Who would have thought one of the simplest life forms has a […]
Leaky Fat Blobs Produced Life
July 7, 2008
“How life began remains an open question,” said David Deamer in Nature,1 then filled the opening with a speculation: maybe life started in leaky blobs of fat. The imaginary first primitive cells would have had a problem. Without transport proteins that control entrances and exits, any lucky ingredients that might have come together […]
Darwinist Reporter Calls Everyone a Hypocrite
July 6, 2008
In a surprising show of journalistic hubris, reporter Robin Nixon of Live Science accused every human being in the world of being a moral hypocrite. “Why We’re All Moral Hypocrites” reported results of a study by Piercarlo Valdesolo at Northeastern University that indicated people tend to judge themselves more leniently than others. […]
Amazing Cell Tricks: Contour Map Navigation
July 5, 2008
Watch a cell divide, and if things go well, it always divides in the middle. How does a cell figure out where its middle is? It follows its contour map. PhysOrg titled its entry, “Dividing cells find their middle by following a protein ‘contour map’.” Cell division, or cytokinesis, is a precisely-controlled operation […]
How to Tell an Evolutionary Story
July 4, 2008
Thanks to Science Daily, we now know that “Evolutionary Origin Of Mammalian Gene Regulation Is Over 150 Million Years Old.” The proof is easy. It is so easy, in fact, that no proof is necessary. One can merely assume it is true. Trust them; they are scientists, after all. Here is how the E word […]
Leaf Vein Patterns Are Not in Vain
July 3, 2008
The vein patterns in a leaf approach perfection. If the requirement is to reach every cell with the shortest and most efficient paths, leaves do it just right. A team of scientists at Cornell, “inspired by plant leaves,” tried to build a network in a polymer substrate that would maximize distribution of fluid with evaporation-driven […]
Saturn Rings: F is for Flamboyant
July 2, 2008
Cassini provides additional evidence that Saturn's F-ring is young.
Can Psychology Figure Out Humans?
July 1, 2008
Psychology is often considered a soft science. Anything they pronounce one year is likely to be modified or overturned the next. A few years ago (and still in some quarters), self-esteem was all the rage (now fading, though; see 05/12/2003). We should be assertive and confident, we were told, and make our feelings […]
Cosmology at the Outer Limits
June 30, 2008
Those who think cosmology could not get any weirder than it already is (01/15/2008) may want to take note of recent pronouncements by the gurus of universal physics. Physics teachers in particular may feel an obligation to state Bob Berman’s disclaimer (10/06/2004) before class: viz, “Warning: The following contains contemporary cosmology. Reading it can produce […]
