For a photo essay about what was happening in our natural world, please see "This Week at Hilton Pond" for the week of 15-21 March 2007 at <<http://www.hiltonpond.org/ThisWeek070315.html>> As always we include a tally of all birds banded or recaptured, plus a slew of shorter phenology notes. There are also links to some recent newspaper and magazine articles about Hilton Pond. 2) Kids Learn Words Best By Working Out Meaning http://www.edu-cyberpg.com/Linguistics/ Toddlers learn new words more easily when they figure out the words' meaning for themselves, research by a 22-year-old Johns Hopkins undergraduate suggests. Not a 'blicket' in the bunch. Meredith Brinster uses nonsense words to determine how toddlers acquire and comprehend unfamiliar vocabulary. Meredith Brinster's original research, suggesting that learning words by inference is more powerful for 3-year- olds than just being told their meaning, is intriguing and may have important implications for the future of teaching, her faculty adviser said. "One of the things that is particularly exciting about the work Meredith is doing is its potential to change the way we think about education and learning," said Justin Halberda, assistant professor of psychological and brain sciences at Johns Hopkins.Interested in how very young children learn to attach the names of objects to the objects themselves, Brinster designed a study to measure which word-learning strategy was more effective: direct instruction, in which an adult "directly" points to and names an unfamiliar object, or inference, in which toddlers use reason (such as process of elimination) to mentally "fasten" an unfamiliar word to an unfamiliar object. Based on previous research, Brinster posited that the young children would learn words more quickly via inference. According to her preliminary results, she was correct. "We found that our hypothesis was true, and that inference is better than instruction," said Brinster, a psychology major. 3) Creepy: Spiders Love to Snuggle http://www.livescience.com/animalworld/070319_sweet_spiders.html Birds do it, bees do it, even baby arachnids do it... While not usually considered paragons of tender, familial love, some spiders do have a touchy-feely side. Scientists have discovered two arachnids that caress their young and snuggle together. Social behavior is extremely rare in arachnids, a group of critters typically defined by their aggression, clever hunting methods and even predatory cannibalism. ?This was the best example I had ever seen of friendly behavior in an arachnid,? said lead study author Linda Rayor, a Cornell University entomologist. 4) Official Defends Editing Climate Papers http://www.physorg.com/news93596017.html A former White House official accused of improperly editing reports on global warming defended his editing changes Monday, saying they reflected views in a 2001 report by the National Academy of Sciences. House Democrats said the 181 changes made in three climate reports reflected a consistent attempt to emphasize the uncertainties surrounding the science of climate change and undercut the broad conclusions that man-made emissions are warming the earth. Philip Cooney, former chief of staff at the White House Council on Environmental Quality, acknowledged at a House hearing that some of the changes he made were "to align these communications with the administration's stated policy" on climate change. The extent of Cooney's editing of government climate reports first surfaced in 2005. Shortly thereafter, Cooney, a former oil industry lobbyist, left the White House to work at Exxon Mobil Corp. 5) 'Generalist' Genes Linked To A Variety Of Learning Disorders http://www.sciencedaily.com/releases/2007/03/070314093311.htm According to a review in the premier issue of Mind, Brain, and Education, the latest research into learning disabilities suggests that ?generalist? genes are responsible for a wide range of learning disorders. ?Old studies tend to focus on finding the genes responsible for single disorders,? says review author Robert Plomin, ?but with the new analysis techniques available, new studies are providing evidence that genes can be responsible for a wide range of learning disorders.? According to Plomin, these ?generalist? genes can be linked to language and math disorders, and even spatial and memory functions. 6) The Brain Loses Neurons During Adolescence http://www.sciencedaily.com/releases/2007/03/070314093257.htm Earlier studies in humans have found gradual reductions in the volume of the prefrontal cortex from adolescence to adulthood, said psychology professor and principal investigator Janice M. Juraska. ?But the finding that neurons are actually dying is completely new. This indicates that the brain reorganizes in a very fundamental way in adolescence.? 7) Action Of Nerves Is Based On Sound Pulses, Anesthetics Research Shows http://www.edu-cyberpg.com/Culdesac/Stars/funkbrothersCulture.html Science Daily Danish scientists challenge the accepted scientific views of how nerves function and of how anesthetics work. Their research suggests that action of nerves is based on sound pulses and that anesthetics inhibit their transmission. The figure shows a biological membrane at its melting point. The green molecules are liquid, and the red are solid. Molecules of anesthetics reduce the number of red areas so that the sound pulse can no longer transport its signal. The nerve is anesthetised. 8) China bans firm from selling land on the moon http://www.physorg.com/news93360534.html 9)_ Cold is hot in evolution -- Researchers debunk belief species evolve faster in tropics http://www.physorg.com/news93190618.html University of British Columbia researchers have discovered that contrary to common belief, species do not evolve faster in warmer climates. UBC Zoology PhD candidate Jason Weir and his mentor Prof. Dolph Schluter, director of the UBC Biodiversity Research Centre, charted the genetic family tree of 618 mammal and bird species in the Americas over the last several million years. By analyzing the DNAs of species that are closely related to one another, the researchers found that speciation the process in which one species splits into two takes place faster in temperate zones than in the tropics. Their findings are published in today?s edition of the journal Science. "It?s been long established that the tropics have more species, but it?s not clear why," says Weir. "The common assumption is that species simply evolve faster in warmer climates." "Our analysis shows that new species actually evolve faster as we move towards the poles. It would take one species in the tropics three to four million years to evolve into two distinct species, whereas at 60 degrees latitude, it could take as little as one million years." The higher speciation rate in higher latitudes, however, is counteracted by a high extinction rate, both likely due to more intense climate fluctuations, says Weir. 10) Music classes are often among the first to be cut when school budgets get tight.
