Foxes zero in on prey via Earth's magnetic field - life - 12 January 2011 - New Scientist - 0 views

  •  
    It sounds like something a guided missile would do. Foxes seem to zero in on prey using Earth's magnetic field. They are the first animal thought to use the field to judge distance rather than just direction.

    If this can be confirmed to be correct, then it should also be able to detect changes in the earth's axis that may be a result of an earthquake or series of earthquakes.

How ancient plants and soil fungi turned Earth green - 0 views

  •  
    ScienceDaily (Nov. 2, 2010) - New research by scientists at the University of Sheffield has shed light on how Earth's first plants began to colonize the land over 470 million years ago by forming a partnership with soil fungi.

New, tighter timeline confirms ancient volcanism aligned with dinosaurs' extinction | E... - 0 views

  •  
    A definitive geological timeline shows that a series of massive volcanic explosions 66 million years ago spewed enormous amounts of climate-altering gases into the atmosphere immediately before and during the extinction event that claimed Earth's non-avian dinosaurs, according to new research from Princeton University. A primeval volcanic range in western India known as the Deccan Traps, which were once three times larger than France, began its main phase of eruptions roughly 250,000 years before the Cretaceous-Paleogene, or K-Pg, extinction event, the researchers report in the journal Science. For the next 750,000 years, the volcanoes unleashed more than 1.1 million cubic kilometers (264,000 cubic miles) of lava. The main phase of eruptions comprised about 80-90 percent of the total volume of the Deccan Traps' lava flow and followed a substantially weaker first phase that began about 1 million years earlier.

Top home-school texts dismiss Darwin, evolution - Yahoo! News - 1 views

  • Christian-based materials dominate a growing home-school education market that encompasses more than 1.5 million students in the U.S. And for most home-school parents, a Bible-based version of the Earth's creation is exactly what they want. Federal statistics from 2007 show 83 percent of home-schooling parents want to give their children "religious or moral instruction." "The majority of home-schoolers self-identify as evangelical Christians," said Ian Slatter, a spokesman for the Home School Legal Defense Association. "Most home-schoolers will definitely have a sort of creationist component to their home-school program." Those who don't, however, often feel isolated and frustrated from trying to find a textbook that fits their beliefs. Two of the best-selling biology textbooks stack the deck against evolution, said some science educators who reviewed sections of the books at the request of The Associated Press. "I feel fairly strongly about this. These books are promulgating lies to kids," said Jerry Coyne, an ecology and evolution professor at the University of Chicago. The textbook publishers defend their books as well-rounded lessons on evolution and its shortcomings. One of the books doesn't attempt to mask disdain for Darwin and evolutionary science. "Those who do not believe that the Bible is the inspired, inerrant Word of God will find many points in this book puzzling," says the introduction to "Biology: Third Edition" from Bob Jones University Press. "This book was not written for them." The textbook delivers a religious ultimatum to young readers and parents, warning in its "History of Life" chapter that a "Christian worldview ... is the only correct view of reality; anyone who rejects it will not only fail to reach heaven but also fail to see the world as it truly is."

    Home-school mom Susan Mule wishes she hadn't taken a friend's advice and tried a textbook from a popular Christian publisher for her 10-year-old's biology lessons. Mule's precocious daughter Elizabeth excels at science and has been studying tarantulas since she was 5. But she watched Elizabeth's excitement turn to confusion when they reached the evolution section of the book from Apologia Educational Ministries, which disputed Charles Darwin's theory. "I thought she was going to have a coronary," Mule said of her daughter, who is now 16 and taking college courses in Houston. "She's like, 'This is not true!'"

Vlastimil Hart: Frontiers in Zoology | Abstract | Dogs are sensitive to small variation... - 0 views

  •  
    "We measured the direction of the body axis in 70 dogs of 37 breeds during defecation (1,893 observations) and urination (5,582 observations) over a two-year period. After complete sampling, we sorted the data according to the geomagnetic conditions prevailing during the respective sampling periods. Relative declination and intensity changes of the MF during the respective dog walks were calculated from daily magnetograms. Directional preferences of dogs under different MF conditions were analyzed and tested by means of circular statistics. Results Dogs preferred to excrete with the body being aligned along the North-south axis under calm MF conditions. This directional behavior was abolished under Unstable MF. The best predictor of the behavioral switch was the rate of change in declination, i.e., polar orientation of the MF. "
