    ScienceDaily (Dec. 1, 2010) - Many coastal wetlands worldwide -- including several on the U.S. Atlantic coast -- may be more sensitive than previously thought to climate change and sea-level rise projections for the 21st century.

    A thought to keep in mind as you read this - what happens to the already overburdened graduate whose job gets outsourced, and then can't find another because he's deemed "overqualified" for the low skilled, low wage jobs available? Answer: Look up "capitalization of interest" and then note that one can't erase student loan debt by declaring bankruptcy. What will result will be the mathematical equivalent of charging compound interest on a loan that the graduate has been deprived of the means of repaying.

    In the past 30 years, a scientific revolution has completely transformed our understanding of babies and young children. Babies both know more and learn more than we would ever have thought possible, and we have recently begun to grasp the mechanisms by which they do this. I wrote The Philosophical Baby to try to show that thinking about childhood can help us answer deep questions about truth, imagination, love, consciousness, identity and morality. Without exaggeration, I believe it can tell us how we came to be human.

    It was supposed to be the first great scientific discovery of the 21st Century - or so many researchers thought when they rushed down to the bookmakers to place bets at what were deemed at the time to be ludicrously generous odds. The physicists believed that they were close to making the first direct detection of gravitational waves, the ripples in space-time generated by supernovas and coalescing neutron stars.

    For anyone who's ever forgotten something or someone they wish they could remember, a bit of solace: Though the memory is hidden from your conscious mind, it might not be gone. In a study of college students, brain imaging detected patterns of activation that corresponded to memories the students thought they'd lost.

    Many, perhaps even most stars, are members of binaries -- two stars that orbit each other. Symbiotic stars are a small subset of binaries with an attitude: they display characteristic, dramatic, episodic changes in the spectra of their light because (it is thought) one star of pair is a very hot, small star while the other is a cool giant.

If bonobo Kanzi can point as humans do, what other similarities can rearing reveal? - 0 views

apes pointing culture learning bonobo

  • The difference between pointing by the Great Ape Trust bonobos - the only ones in the world with receptive competence for spoken English - and other captive apes that make hand gestures is explained by the culture in which they were reared, according to the paper's authors: Janni Pedersen, an Iowa State University Ph.D. candidate conducting research for her dissertation at Great Ape Trust; Pär Segerdahl, a scientist from Sweden who has published several philosophical inquires into language; and William M. Fields, an ethnographer investigating language, culture and tools in non-human primates. Fields also is Great Ape Trust's director of scientific research. Because Kanzi, Panbanisha and Nyota were raised in a culture where pointing has a purpose - The Trust's hallmark Pan/Homo environment, where infant bonobos are reared with both bonobo (Pan paniscus) and human (Homo sapiens) influences - their pointing is as scientifically meaningful as their understanding of spoken English, Fields said. The pointing study supports and builds on previous research on the effect of rearing culture on cognitive capabilities, including the 40-year research corpus of Dr. Duane Rumbaugh, Dr. Sue Savage-Rumbaugh and Fields, which is the foundation of the scientific inquiry at Great Ape Trust. Those studies included the breakthrough finding that Kanzi and other bonobos with receptive competence for spoken English acquired language as human children do - by being exposed to it since infancy. The bonobos adopted finger-pointing behavior for the same reasons, because they were reared in a culture where pointing has meaning.

    You may have more in common with Kanzi, Panbanisha and Nyota, three language-competent bonobos living at Great Ape Trust, than you thought. And those similarities, right at your fingertip, might one day tell scientists more about the effect of culture on neurological disorders that limit human expression. Among humans, pointing is a universal language, an alternative to spoken words to convey a message. Before they speak, infants point, a gesture scientists agree is closely associated with word learning. But when an ape points, scientists break rank on the question of whether pointing is a uniquely human behavior. Some of the world's leading voices in modern primatology have argued that although apes may gesture in a way that resembles human pointing, the genetic and cognitive differences between apes and humans are so great that the apes' signals have no specific intent. Not so, say Great Ape Trust scientists, who argued in a recently published scientific paper, "Why Apes Point: Pointing Gestures in Spontaneous Conversation of Language-Competent Pan/Homo Bonobos," that not only do Kanzi, Panbanisha and Nyota point with their index fingers in conversation as a human being might, these bonobos do so with specific intent and objectives in mind.

home schoolling Christian evolution propoganda

shared by Skeptical Debunker on 07 Mar 10 - Cached
  • 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!'"

    "A quest that began over a decade ago with a chance observation has reached a milestone: the identification of a gene that may regulate regeneration in mammals. The absence of this single gene, called p21, confers a healing potential in mice long thought to have been lost through evolution and reserved for creatures like flatworms, sponges, and some species of salamander. In a report published today in the Proceedings of the National Academy of Sciences, researchers from The Wistar Institute demonstrate that mice that lack the p21 gene gain the ability to regenerate lost or damaged tissue."

    "Oxygen may not be the staple of modern complex life that scientists once thought. Until now, the only life forms known to live exclusively in anoxic conditions were viruses, bacteria and Archaea. But in a new study, scientists have discovered three new multicellular marine species that appear to have never lived in aerobic conditions, and never metabolized oxygen. "

    For many years, neurons were thought to be alone in executing this task, and glia were consigned to a supporting role regulating a neuron's environment, helping it to grow, and even providing physical scaffolding (glia is Greek for 'glue'). In the past couple of decades, however, this picture has been changing.

particle physics supersymmetry

shared by Charles Daney on 31 Jan 11 - No Cached
  • Charles Daney on 31 Jan 11
     
    Of the many ideas for new physics that can be tested at the Large Hadron Collider (LHC), supersymmetry is one of the most promising. The theory proposes that each fundamental fermion particle has a heavier bosonic superpartner (and vice versa for each fundamental boson) and by doing so, offers an extension of the standard model of particle physics that fixes many of its problems. None of the known particles appear to be superpartners, however, which leads to the daunting conclusion that if supersymmetry is correct, there are more than twice as many fundamental particles as we thought, but we have only been left with the lightest partners; that is, supersymmetry is broken.

New MRSA superbug discovered in cows' milk - health 03 June 2011 Scientist

    A new strain of MRSA has been identified in cows' milk and in people, but don't stop drinking milk - the bug is killed off in pasteurisation. However, the strain evades detection by standard tests used by some hospitals to screen for MRSA (methicillin-resistant Staphylococcus aureus), potentially putting people at risk. Laura Garcia Alvarez, then at the University of Cambridge, and colleagues were studying infections in British cows when they discovered antibiotic-resistant bacteria that they thought were MRSA. However, tests failed to identify the samples as any known strains of the superbug. Sequencing the mystery bacteria's genomes revealed a previously unknown strain of MRSA with a different version of a gene called MecA. The new strain was also identified in samples of human MRSA, and is now known to account for about 1 per cent of human MRSA cases.

    Most people would agree that culture can have a large effect on our daily lives - influencing what we may wear, say, or find humorous. But many people may be surprised to learn that culture may even effect how our brain responds to different stimuli. Indeed, until recently, most psychology and neuroscience researchers took for granted that their findings translated across individuals in various cultures. In the past decade, however, research has begun to unravel how cultural belief systems shape our thoughts and behaviors.
