NASA Science News for October 3, 2006 http://science.nasa.gov/headlines/y2006/03oct_novarupta.htm?list111411
The most powerful volcanic eruption of the 20th century happened in Alaska at a volcano named Novarupta. Because Novarupta was located so near the Arctic, it did some curious things to Earth's climate. Almost a century after the blast, researchers are beginning to understand what happened.
Hilton Pond 09-22-06 (Goldenrod Predators) http://www.hiltonpond.org/ThisWeek060922.html
Although Carolina habitats might not be all that scary for humans, even such seemingly innocuous sites as Goldenrod patches can be places of no return for many small organisms.
For a close look at some of the denizens that lurk among the Solidago and raise havoc with everything from Honeybees to aphids, please visit the 22-30 September 2006 installment of "This Week at Hilton Pond".
Following the photo essay we include our usual tally of birds banded during the period, as well as a list of recaptures and several miscellaneous nature notes. Of particular interest is a follow-up note about Kudzu.
Space Weather News for Oct. 6, 2006 http://spaceweather.com
HARVEST MOON: Tonight's full moon has a special name--the "Harvest Moon." It is the full moon closest to the northern autumnal equinox. Long ago, before electric lights, farmers relied on the Harvest Moon to light up their fields at night, allowing them to harvest autumn crops even after sunset. The Harvest Moon of 2006 is a big one--almost 12% wider than some full Moons we've seen earlier this year. Why? Because the Moon is near perigee, the side of the Moon's lopsided orbit that comes closest to Earth.
Next on NOVA: "The Viking Deception" http://www.pbs.org/nova/vinland Tuesday, October 10 at 8PM ET/PT on PBS Check your local listings as dates and times may vary.
There are few more tantalizing or notorious historical documents than the Vinland Map. A faded, yellowing scrap of parchment bearing a faint tracery of lines, the map apparently shows part of the eastern seaboard of North America -- yet it was purportedly drawn at least half a century before Columbus reached the New World. It seems to present unshakeable proof that the Vikings were the real discoverers of the Americas. But for 40 years, a bitter debate over its authenticity has raged among cartographers, historians, and scientists. Despite chemical analysis and radiocarbon tests, the case remained unresolved. Now, in an exclusive investigation, NOVA presents fresh evidence confirming that the map was probably one of the cleverest forgeries of all time, and probes who might have wanted to carry out the deception.
Here's what you'll find online:
The Forger's Inspiration Early Viking tales and genuine medieval maps likely influenced the Vinland Map's author. http://www.pbs.org/wgbh/nova/vinland/inspiration.html
Who Were the Vikings? Smithsonian archeologist William Fitzhugh reveals what drove the Vikings on their unquestionably real adventures to distant shores. http://www.pbs.org/wgbh/nova/vinland/vikings.html
The Map in Question Is it authentic? Examine the entire map -- and the telltale evidence -- and decide for yourself. http://www.pbs.org/wgbh/nova/vinland/map.html
Famous Fakes Hitler's diaries, Howard Hughes's autobiography, and other famous forgeries were made for money, power, or simply the thrill of the hoax. http://www.pbs.org/wgbh/nova/vinland/fakes.html
[EDInfo] Teaching Resources: Earth Science, Cancer, the Brain
"Arctic and Antarctic" looks at research being conducted in the two polar regions of earth. These vast, icy, inhospitable environments provide "natural laboratories" for scientists to study basic questions: How did the universe begin? Is earth's climate changing? What are the limits of life in extreme environments? (NSF) http://nsf.gov/news/overviews/arcticantarctic/index.jsp
"Disasters" provides an overview of research aimed to anticipate disasters and minimize their effects. Learn about research on hurricanes, earthquakes, and volcanoes. See what scientists are discovering about how and when tornadoes will form. Watch a simulated fire spread up a hill. (NSF) http://www.nsf.gov/news/special_reports/disasters/index.jsp
"Climate Discovery Teacher's Guide" includes lessons on how the sun's magnetism interacts with the earth's magnetic field, how scientists study ancient climates, how the earth system works, how climate changes over time, and how climate models are used to predict the future of earth's climate. (NSF) http://eo.ucar.edu/educators/ClimateDiscovery/
"Inside Cancer" Inside Cancer uses animations and videoclips of experts to reveal what is known about cancer. Learn about kinds of cancer, how they start (cell mutations), and their distribution worldwide. Explore cancer related factors -- smoking, inheritance, diet, and others. Find out about diagnosis and treatment. See animations of key concepts; hear experts explain them. (NIH) http://www.insidecancer.org/
"MaudNESS Cruise" tells the story of a 56-day cruise into the Southern Ocean (Antarctic) to learn about conditions and events that cause ocean circulation, a key factor in setting the climate around the world. The story is told through the journal of a 5th grade teacher aboard the icebreaker ship. Learn about crew members (their roles and backgrounds). See instruments used to measure salinity, oxygen, ice, and weather. Discover what the crew learned. (NSF) http://www.esr.org/maudness_cruise/cruise_main.html
"Monarchs in the Classroom" focuses on research and understanding of monarch butterflies. Learn about their growth, natural enemies, interactions with milkweed, migration, population dynamics, and more. (NSF) http://www.monarchlab.umn.edu/default.aspx
"Neuroscience for Kids" explores the brain and nervous system. Learn about brain development, brain lobes, the cerebral cortex, the skull, blood supply, brain fitness, neurons, the autonomic nervous system, sensory systems, the spinal cord, laughter and the brain, the musical brain, face recognition, drug effects, neurological and mental disorders, and more. (NIH) http://faculty.washington.edu/chudler/neurok.html http://www.edu-cyberpg.com/NCFR/health.html
"ScienCentralNews" provides the latest news on developments in life sciences, physical sciences, and technology. Sort articles by topic -- genetics, animals, the brain, chemistry, physics, earth, oceans, astronomy, climate, engineering, biotechnology, computers, nanotechnology, and others. See articles on cancer causing genes, music for pain, fat vaccine, biofuel energy, no-mow grass, liquid armor, fouled beaches, phones and driving, auto-focus eyewear, activity breaks and memory, and more. (NSF) http://www.sciencentral.com/
