More Impacts on Crater Count Dating
September 25, 2007
Planetary scientists have relied on crater counts to estimate the surface age of a planet or moon. The more craters, the older the surface. This method has recently come under closer scrutiny (see 10/20/2005) because of the phenomenon of secondary cratering. A simplistic look at a crater-scarred planet or moon might lead one […]
Upsets: Assumptions About Genes, Atmospheres Challenged
September 24, 2007
It’s not fun when a whole superstructure of scientific theories and models is found to rest on a shaky foundation. That’s just what may be happening in two very different fields: genetics and planetary science: Lateral pass to the opposing team: Building evolutionary trees by comparing genomes was supposed to be simple. Sure, geneticists knew […]
Thermodynamics: The Real Theory of Everything
September 23, 2007
Need a theory of everything? Try thermodynamics. Mark Haw reviewed a new book by Peter Atkins on the subject in Nature,1 Four Laws that Drive the Universe (Oxford, 2007). He had high praise for the achievements of the “19th century grandees” Joule, Maxwell and Kelvin: Thermodynamics ought to be the cornerstone of any scientist’s understanding […]
Early Beetle Was Armed
September 23, 2007
According to Live Science, a beetle preserved in amber, dated at 100 million years old, was caught in the act of using chemical warfare. “Soldier beetles” capable of this kind of advanced defense system were not thought to have evolved till 60 million years later. This article contains several statements worthy of the […]
Was Velociraptor a Dragon?
September 22, 2007
As if Velociraptor, the terror of Jurassic Park, was not scary enough, some scientists are now saying it was feathered. (This, of course, does not imply it could fly after its human prey like some movie dragon.) The latest claim in Science is based on the apparent presence of “quill knobs” on the radius bone […]
Mars Was and Is Dry
September 21, 2007
The cover story of Science this week has bad news for those hoping for Martian lakefront property. A series of articles by planetary scientists who studied images from the Mars Reconnaissance Orbiter casts strong doubt on the presence of water on Mars, even in the planet’s early days. The overview article by Richard Kerr in […]
Geological Dates Adjust Catastrophically to Evolutionary Assumptions
September 19, 2007
Pick a date for the rise of a land mass: 3 million years or 30 million years. Either one will work, depending on the current evolutionary assumptions, if one is to follow the logic of an article on the Discovery Channel website. Here’s how it began: The geologic rise of the Ethiopian Plateau may have […]
Early Reptile Had Modern Ears
September 18, 2007
Modern ears are nothing new; they go back 260 million years. That’s the gist of a paper in PLoS ONE that reported on a Russian reptile fossil.1 The research team was surprised to discover that the creature had impedance-matched ears, a novelty thought to have evolved 50 million years later. Somehow this innovation survived one […]
Dust to Dust, or Dust to Life?
September 17, 2007
National Geographic gave prominent press to last month’s theory of living dust (see 08/10/2007, bullet 1). Criticisms were mild; scientists were quoted who thought this claim raises interesting questions about the definition of life. Tsytovich’s ideas were described by Mihaly Horanyi (U of Colorado) as “amazing.” He said, “This is a very original, very intelligent […]
Dark Matter Sheds Light on Invisible Stars: Come Again?
September 17, 2007
Can one unknown shed light on another unknown? That’s what some UK astronomers seem to be saying. Before describing their model, consider this conundrum with which they ended a story in the BBC News: “We don’t know what the dark matter is, we don’t know what the first stars are. If we bring these two […]
Review: The Case for Christ DVD
September 16, 2007
A film adaptation of Lee Strobel’s best seller The Case for Christ (1998) was released by La Mirada Films on September 11. Strobel, a former legal reporter for the Chicago Tribune, and an atheist, was determined to disprove the miracles and resurrection of Jesus Christ after his wife converted to Christianity. His two-year investigation of […]
Some Christian Colleges Love Darwin More than Jesus
September 14, 2007
“If you love me, keep my commandments,” Jesus said. He told his disciples to expect persecution. He commanded them to take up their cross and follow him, explaining that as the world hated him, it would hate them. Counting the cost, the early disciples did indeed love and follow him to the death. […]
Iapetus update
September 13, 2007
The data have returned from Cassini’s closest-ever flyby of Iapetus (see 09/07/2007). All the images can be found at Cassini Multimedia raw images, with good samples posted by the imaging team here and here. Amateurs and pros at Unmanned Spaceflight started getting really excited at 12:40 a.m. Tuesday when the images hit the […]
Genetics Central Dogma Is Dead
September 12, 2007
The science of life is undergoing changes so jolting that even its top researchers are feeling something akin to shell-shock.
New World Record for Winged Migration
September 11, 2007
The BBC News reports that a female bar-tailed godwit flew 11,500km (almost 7200 mi) nonstop from Alaska to New Zealand. The journey took about a week. Observers at Massey University used electronic tags to catalog the birds’ flight. This distance is nearly double what ornithologists used to consider an “extremely long” flight. This […]
