Tales of Two Footprints
August 27, 2007
Footprints in the sands of time have been found at two different locations. What tales do they tell? One is a footprint of a Roman soldier. EurekAlert described how the sandal print was uncovered at Hippos, or Susita, on a hill east of the Sea of Galilee. It hints that soldiers participated in […]
Evolution Takes Credit
August 24, 2007
It may be more blessed to give than to receive, but evolution often just takes.
Fossil Gorilla Forces Hominid Ancestor Earlier
August 23, 2007
A set of gorilla teeth found in Ethiopia pushes the evolutionary story of a split between apes and humans back almost twice as far as previously thought. Nature reported the fossil announcement that estimated the date of the teeth as 10.5-11 million years old.1 The prior estimate for a human-ape divergence was about 6 million. […]
Hollywood Film to Expose Darwin Dogma
August 22, 2007
Darwin is going to get a surprise on his birthday next year. Ben Stein is releasing a film on Feb. 12, 2008, entitled “Expelled: No Intelligence Allowed.” The gift may not be what Darwin wants. The press release subtitle asks, “Whatever happened to free speech?” Apparently Premise Media decided to document the trend among Darwinists […]
Crows Use Tools on Tools
August 21, 2007
Crows can use one tool on another to get food. A report in Science Daily says they appear to use analogical reasoning, not just trial and error, to figure out how to manipulate objects. They used a short stick to get a longer stick out of a toolbox in order to reach a snack too […]
Two Ways to Look at a Fin
August 21, 2007
Two science articles this month showed very different ways to look at a fish fin. One looked for evolution; the other looked for design. One tried to trace an evolutionary story with no practical application; the other tried to find ways to improve our lives. The evolutionary story involved a fossil coelacanth. Science […]
Mystery of the Ultraconserved Elements, Cont.
August 18, 2007
ejerano et al reported ultraconserved elements in the human genome (05/27/2004). These were non-coding regions that, for some unknown reason, showed no evolution between mouse and human – a time span over tens of millions of years. Since many of these ultraconserved regions are also found in bird genomes, they added that some genetic regions […]
SETI Camp Promotes Make Believe
August 17, 2007
“Every kid loves to play make believe,” wrote Lisa Grossman for Space.com’s “SETI Thursday” feature. How did Lisa spend her summer? Playing make believe with 16 undergraduates at a NSF- and NASA-funded SETI camp. “For many of us, the experience was nothing short of fantasy fulfillment,” she cheerfully said in her report entitled, “How I […]
Artificial Selection Is Not Natural Selection
August 16, 2007
From Nature1 comes this point to ponder: Evolution has crafted thousands of enzymes that are efficient catalysts for a plethora of reactions. Human attempts at enzyme design trail far behind, but may benefit from exploiting evolutionary tactics. The subheading summarized a commentary by Michael P. Robertson and William G. Scott (UC Santa Cruz) on “directed […]
Stupid Evolution Quote of the Week: Shark Chefs and
Finger Food
August 15, 2007
A press release from University of Florida wins this week’s prize for trying to make dogmatism funny (or at least appealing to snackers): When the first four-legged animals sprouted fingers and toes, they took an ancient genetic recipe and simply extended the cooking time, say University of Florida scientists writing in Wednesday’s issue of the […]
Largest Dinosaur Mass Grave in Switzerland Found
August 15, 2007
As many as 100 plateosaurs may be buried in a mass grave in Switzerland, reported the Reuters news service. “The finds show that an area known for Plateosaurus finds for decades may be much larger than originally thought” – as much as a mile in width in the town of Frick, near the German border. […]
Gratitude Protects Against Health Loss
August 15, 2007
A study in the “new science of gratitude” showed that thankfulness is good therapy. Researchers at UC Davis and Mississippi University for Women tracked 12 female patients who kept journals of their hospital stays while receiving organ transplants. A control group just reported “medication side-effects, how they felt about life overall, how connected they were […]
DNA Repair Is Highly Coordinated
August 14, 2007
The remarkable ability of cells to repair DNA damage has been the subject of several recent articles. As a long, physical molecule subject to perturbing forces, DNA is subject to breakage on occasion. If repair mechanisms were not in place, the genetic information would quickly become hopelessly scrambled and life would break down. Studies are […]
Science Confronts Philosophy, or Vice Versa
August 13, 2007
Practicing scientists often disdain philosophy. To them, it seems like mumbo-jumbo with convoluted arguments telling them why they don’t exist or why two-ness cannot be represented on a chalkboard. To a scientist dealing with real lab rats or chemicals off the shelf, such ramblings seem detached and worthless. Who would know more what science is […]
Immune System Appeared Early
August 12, 2007
“Social amebas” or slime molds have gotten praise recently as inventors of the immune system. These amebas can band together in a “slug” that can move as a unit and generate stalks and spores. Science Daily reported on research at Baylor College of Medicine that found “sentinel cells” in a colony of amebas that patrol […]
