Did Darwinism Build the Nuclear Pore Complex?
February 2, 2008
After nine years of work, three universities including a team at Rockefeller University completed a beautiful new model of the nuclear pore complex. The story is told by Science Daily. The article attributed the origin of this exquisite gatekeeper of the nucleus to evolution: “their findings provide a glimpse into how the nucleus […]
Deep Sea Hydrocarbons Dont Require Life
February 1, 2008
Remember the “Lost City” deep sea vents that were discovered by surprise in 2000 (12/13/2000)? It appears that they are producing large quantities of hydrocarbons (methane, alkanes, ethene, acetylene, propene, propyne) without the help of living organisms (cf. 08/13/2002). A team of scientists deduced that abiogenic reactions like the Fischer-Tropsch process and others may be […]
Nose Code Rockets Smell Discrimination
February 1, 2008
You have a code in your nose. Scientists working on fruit fly olfactory systems have found that a mapping mechanism between components maximizes the fly’s ability to discriminate smells. The coding system provides a non-linear response that appears finely tuned to maximize the information content of odor inputs. The components of this system […]
Explorer 1 Chief Discovers Design
January 31, 2008
On this day 50 years ago, America entered the space race. On January 31, 1958, America gave its answer to Sputnik: a civilian satellite named Explorer 1. Within a few hours of the time of day these words are being written, von Braun’s Jupiter-C rocket at Cape Canaveral, Florida, successfully launched a JPL satellite into […]
A Step Closer to Gecko Adhesive
January 30, 2008
Scientists are getting closer to imitating the amazing wall-climbing ability of geckos. Science Daily reports that a team from UC Berkeley manufactured tape with hard polymer fibers just 600 nanometers across that mimic the spatulae on gecko feet. This latest attempt at imitating the gecko works only on smooth, clean surfaces, but requires […]
Hidden Messages Found in DNA
January 29, 2008
DNA contains the language of life, but what would happen if someone found hidden messages in the genetic code? Such a thing actually happened, reported the New York Times. When Craig Venter’s lab produced an artificial organism, they inserted hidden “watermarks” into the genome: his name, the names of co-workers, and the name of the […]
A Pitcher of Health, and Reasons to Love Slime
January 28, 2008
Pitcher plants contain chemicals that just might help medicine and agriculture, reported PhysOrg. A Japanese team found a myriad of interesting proteins in this “evolutionary marvel,” a plant that eats insect meat. Now for some slimy good news. PhysOrg said, “You know algae. It’s the gunk that collects on the sides of a […]
Horseshoe Crabs Unchanged Since Ordovician
January 28, 2008
A fossil horseshoe crab has been discovered in Canada that pushes back their origins at least 100 million years in the evolutionary timetable. The previous record placed these marine arthropods in the Carboniferous (350 million years BP in the geologic column); others were known from the Jurassic. “Both the Carboniferous and the Jurassic fossil discoveries […]
Molecular Phylogeny Is a Mess of Uncertainty
January 26, 2008
Genomes galore – a great opportunity to study evolution, right? Think again. A paper in Science by Wong et al1 revealed systematic uncertainty in the way genomes are compared, leading to bias that makes genetic comparisons essentially useless. Antonis Rokas, in the same issue,2 began his commentary on this problem thus: Darwin relied on fossils, […]
Leslie Orgel’s Last Testament: Pigs Don’t Fly, and Life Doesn’t Just Happen
January 26, 2008
Leslie Orgel's last written article before his death shows no patience for hypothetical scenarios for the origin of life.
The Geologists Were Wrong
January 25, 2008
More examples of collapsing theories have appeared in the literature this week (compare last week, 01/21/2008): Dirty Comet: The Stardust spacecraft that collected comet samples in 2006 was so named because it was believed comets contained pristine material from the birth of the sun. That has all changed. National Geographic News summarized a paper in […]
Do Chicks Tell Dinosaur Tales?
January 25, 2008
For years, evolutionary biologists have battled over the origin of flight. Did dinosaurs run along the ground and take off, or did they jump from trees? The first idea is called the cursorial hypothesis; the latter, the arboreal hypothesis. In 2003, Ken Dial [U Montana] had an idea: maybe watching partridge chicks could inform the […]
Getting a Hand on Facts and Meanings
January 24, 2008
What could be more simple than pressing a button with your finger? That “seemingly trivial action is the result of a complex neuro-motor-mechanical process orchestrated with precision timing by the brain, nervous system and muscles of the hand.” So says a press release from University of Southern California posted on EurekAlert. Simple, everyday […]
Nuke Sand, Get Life
January 23, 2008
Glowing sand was your cradle, claimed The Telegraph. “The sifting and collection of radioactive material by powerful tides could have generated the complex molecules that led to the evolution of carbon-based life forms –including plants, animals and humans.” The article acknowledged that “radiation may seem an unlikely candidate to kick-start life because it […]
Life Influences Dating Method
January 22, 2008
The rate of calcium carbonate precipitation can double if microbes are present, says an article in PhysOrg. Scientists studying hot spring deposits in Yellowstone made this “surprising discovery about the geological record of life and the environment.” The article adds, “Their discovery could affect how certain sequences of sedimentary rock are dated, and how scientists […]
