Survey of Mexican Migrants, Part Two: Attitudes About Voting in Mexica
This survey, released in March 2005, reports that of the "nearly 5,000 Mexican migrants who were interviewed while applying for identity cards at Mexican consulates in the United States ... an overwhelming majority would vote in Mexican elections scheduled for next year if they had the opportunity."Includes a summary and the complete report. From the Pew Hispanic Center. New record in the area of prime number decomposition of cryptographica
An international team of scientists has obtained the prime factors of the RSA challenge number RSA-768, using the Number Field Sieve. Man-made Wetland's Effectiveness Similar To Natural Marsh
Researchers who studied a man-made wetland in Ohio for two years concluded that the created wetland filtered and cleaned water as well as or better than would a natural marsh. Sun's Direct Role In Global Warming May Be Underestimated, Duke Physic
At least 10 to 30 percent of global warming measured during the past two decades may be due to increased solar output rather than factors such as increased heat-absorbing carbon dioxide gas released by various human activities, two Duke University physicists report. 'Orbitronics' Could Keep Silicon-based Computing Going After Today's T
For about 40 years, the semiconductor industry has been able to continually shrink the electronic components on silicon chips, packing ever more performance into computers. Now Stanford University physicists present ''orbitronics,'' an alternative to conventional electronics that could someday allow engineers to skirt a daunting limit while still using cheap, familiar silicon. Where Religious Belief And Disbelief Meet
While the human brain responds very differently to religious and nonreligious propositions, the process of believing or disbelieving a statement, whether religious or not, seems to be governed by the same areas in the brain. Diabetes, Hypertension And Obesity Negatively Effect Joint Replacement
Using a database of nearly 1 million Americans who underwent major joint replacement surgery, a team led by researchers at Duke University Medical Center have determined those surgical patients with diabetes, hypertension or obesity were significantly more likely to suffer post-operative complications. NASA'S Live Tropical Sea Surface Temperature Web Site Gives Climate, H
Sea surface temperatures give scientists information about ocean currents, climate, climate change and how a hurricane may evolve. Now, NASA has a Web page that provides frequent updates on changing ocean temperatures. Canada: Alberta's Hidden Valleys Offer Both Resources And Danger
Alberta is crisscrossed with hidden glacial valleys that hold both resource treasures and potential danger. Researchers discovered a 300-meter-deep valley hidden beneath the surface of the ground near the community of Rainbow Lake in northwestern Alberta. Scientists Seeking Biocontrols Against Sharpshooters
Help may be on the way from Agricultural Research Service (ARS) scientists in Argentina and Texas for grape growers in California who are battling the glassy winged sharpshooter. A parasitic wasp could help growers ward off the glassy winged sharpshooters (GWSS) that have been spreading plant-damaging Xylella fastidiosa bacteria in southern California vineyards since the 1990s.
