Study shows math mentors much more effective in beginning of careerA new Northwestern University study of mentor-protégé relationships has found something that parents and children have known for a long time: the generation gap is real, and it matters. It not only affects communication but also who mentors young mathematicians successfully and who does not.Northwestern researchers analyzed 60 years of a "family tree" of mathematicians and the doctoral students they advised....
Three new UCSF studies describe the wide reach of the tobacco industry and its influence on young people, military veterans and national health care reform.The analyses will be published in a special July edition of the American Journal of Public Health titled "Modeling to Advance Tobacco Control Policy."Findings are available online at http://www.ajph.org/first_look.shtml and coincide with a global event designed to heighten awareness of tobacco use and its negative health effects: World No...
'South-South' biotech collaborations boost health, economies: StudyThe availability of more affordable drugs, vaccines and diagnostics that would help countless people worldwide is the foremost benefit expected from a growing number of collaborations between biotech firms in developing countries, according to a study to be published Mon. May 12 in the UK journal Nature Biotechnology.Researchers from five developing countries, together with colleagues at Canada's McLaughlin-Rotman Centre for...
DNA testing of garden ferns sold at plant nurseries in North Carolina, Texas, and California has found that plants marketed as American natives may actually be exotic species from other parts of the globe.The finding relied on a new technique called "DNA barcoding" that uses small snippets of DNA to distinguish between species, in much the same way that a supermarket scanner uses the black lines in a barcode to identify cans of soup or boxes of cereal.A team of North Carolina...
Children normally experience flights of fancy, including imaginary friends and conversations with stuffed animals, but some of them are also having hallucinations and delusions which might be the early signs of psychosis.A study of British 12-year-olds that asked whether they had ever seen things or heard voices that weren't really there, and then asked careful follow-up questions, has found that nearly 6 percent may be showing at least one definite symptom of psychosis.The children who...
University investment decisions can deepen job losses and other financial cuts when market collapses carve into budget-supporting endowment funds, a new study by the National Bureau of Economic Research found.Researchers say the findings show that universities need to re-evaluate investment portfolios and policies to cushion the blow when market downturns wither endowments, a growing economic engine for colleges over the last two decades."A secretary at Harvard probably had no idea her...
Imagine if your computer only allowed you to see one line at a time, no matter what you were doing "“ reading e-mail, looking at a Web site, doing research. That's the challenge facing blind computer users today. But new research from North Carolina State University is moving us closer to the development of a display system that would allow the blind to take full advantage of the Web and other computer applications."Right now, electronic Braille displays typically only show one line of text...
A group of astronomers [1], led by Tim Schrabback of the Leiden Observatory, conducted an intensive study of over 446 000 galaxies within the COSMOS field, the result of the largest survey ever conducted with Hubble. In making the COSMOS survey, Hubble photographed 575 slightly overlapping views of the same part of the Universe using the Advanced Camera for Surveys (ACS) onboard Hubble. It took nearly 1000 hours of observations.In addition to the Hubble data, researchers used redshift [2]...
A University of Illinois researcher advises caution when trying to characterize gender roles and sexual behavior among this country's Latino adolescents and young adults."When a recent documentary about U.S. Latinos featured two teen mothers in a 90-minute program, the Latino students in my classes thought it was an unbalanced portrayal of their community"”and they were right!" said Marcela Raffaelli, a U of I professor of human and community development and co-author of a...
Civil engineers at the University of Washington and the U.S. Army Corps of Engineers' Seattle office have taken a first look at how dams in the Columbia River basin, the nation's largest hydropower system, could be managed for a different climate.They developed a new technique to determine when to empty reservoirs in the winter for flood control and when to refill them in the spring to provide storage for the coming year. Computer simulations showed that switching to the new management system...
