2006 AAAS Annual MeetingErnst Mayr's theory illustrated in genetic epidemiology studies An evolutionary and population biologist at Washington University in St. Louis says that Mayr's theory has been illustrated nicely in recent years in human genetic epidemiology and population biology studies. Alan R. Templeton, PhD, Washington University professor of biology in Arts & Sciences, said that there is an extensive documentation of genetic interaction over the past few years including his own genetic epidemiology studies of coronary artery disease (CAD).

2006 AAAS Annual MeetingModern mathematical proofs changing due to collaborations, computers A Missouri mathematician believes that the state's moniker has great bearing on the status of modern mathematical proofs: Show me. Steven Krantz, PhD, a professor of mathematics in Arts & Sciences at Washington University in St. Louis, said that it is becoming more difficult to verify proofs today and that the concept of the proof has undergone serious change over the course of his 30-plus years career.

2006 AAAS Annual MeetingToxic waves According to new statistics, 2005 was the second deadliest on record for Florida's endangered manatees. A leading cause of the fatalities was the toxins produced by "red tide" blooms of the dinoflagellate Karenia brevis, which appear to be growing increasingly common in Florida. Gregory Bossart, from the Harbor Branch Oceanographic Institution in Ft. Pierce, Fla., and colleagues, have conducted research to be presented at AAAS suggesting that the impacts of the toxins are increasing for humans as well.

2006 AAAS Annual MeetingScience education lacks a good narrative There is a good story behind science, but no one is telling it in American classrooms. According to Ursula Goodenough, PhD, a professor of biology in Arts & Sciences at Washington University in St. Louis, science continues to be taught from K-12 to the college and university levels, in fragmented, incoherent bits and pieces rather than a coherent narrative, a history of nature.

2006 AAAS Annual MeetingPennsylvania tackles nano engineering education From medicine to materials and manufacturing, nanotechnology is today's watchword but what we do with these new technologies depends on people, and Pennsylvania is leading the way in training nanotechnologists at all levels for all types of nanotech.

2006 AAAS Annual MeetingBesides food, farming can provide wildlife habitat and reduce global warming When people hear the word "agriculture," most think of food. But the benefits of agriculture are much more than farm fresh corn or dairy products. Now scientists are investigating how farmers can manage their land to offer everyone more environmental benefits, and whether farmers could be paid for providing these benefits.

2006 AAAS Annual MeetingStanford scholar, aka NPR's 'Math Guy,' explains changing nature of mathematical proof On Feb. 18, Keith Devlin will reveal how mathematicians know what they know. ''Mathematics was built on this comforting idea, of truth being established by proof, that was around for 2,000 years,'' Devlin said. ''Then, in the second half of the 20th century, several major results were proved by methods that challenge that, and as a result we've had to reassess what we mean by proof.''

2006 AAAS Annual MeetingCrossing the Valley of Death: Moving science into practice and policy Society can't afford to take decades to put new insights about the environment into practice, say two scientists from The University of Arizona in Tucson. To shorten the time between the scientific acceptance of new knowledge and its widespread application by citizens and policymakers -- the so-called "Valley of Death" -- environmental scientists need to apply research on how innovations are disseminated and research from marketing.

2006 AAAS Annual MeetingCan science-based resource management work? The Valles Caldera National Preserve in New Mexico is a unique experiment in integrating science into the management of public lands. Thomas W. Swetnam, an original board member of the trust that manages the preserve, will discuss the history of the preserve and its innovative management on Friday, Feb. 17 at the American Association for the Advancement of Science meeting in St. Louis.

2006 AAAS Annual MeetingDetermining curriculum effectiveness "This discussion of how to establish curricular effectiveness in mathematics is particularly relevant in light of President Bush's State of the Union address and budget, which includes significant expenditures on improving mathematics and science education in this country," said Jere Confrey, PhD, a professor of mathematics education at Washington University in St. Louis. "If the funds are to make a difference, thorough, valid and fair evaluations of materials will be critical." Contact: Neil Schoenherr

2006 AAAS Annual MeetingWorld faces challenge as life expectancies lengthen, scientist says In the 21st century, state-of-the-art anti-aging technologies may extend human lifespans at an unprecedented rate, bringing with them a host of social and economic challenges, says biologist Shripad Tuljapurkar of Stanford University. He will present his findings on Feb. 17 at the annual AAAS meeting in St. Louis. Contact: Mark Shwartz

2006 AAAS Annual MeetingGrand challenges, national lab-style The W.R. Wiley Environmental Molecular Sciences Laboratory (EMSL), a Department of Energy-sponsored national scientific user facility, is seeing early promise from its two scientific "grand challenges" that have been investigating enigmas in microbiology and biogeochemistry.

2006 AAAS Annual MeetingHigh school AP courses do not predict college success in science A survey of 18,000 college students enrolled in introductory biology, chemistry, and physics has found little evidence that high school Advanced Placement (AP) courses significantly boost college performance in the sciences. The study by researchers at Harvard University and the University of Virginia found the best predictors of success in college science courses to be high school classes that foster mathematical fluency, value depth over breadth, and feature certain types of laboratory work.

2006 AAAS Annual MeetingToo much sugar not good for coral reefs The race is on to buy up inexpensive land along coastlines for vacation homes and tourist hotels. But increased development can mean more nutrient rich runoff that threatens the very coral reefs attracting tourists in the first place. David Kline at the Smithsonian Tropical Research Institute and colleagues find that bacteria on coral reefs grow out of control as the level of simple sugars in seawater increases. Contact: Beth King

2006 AAAS Annual MeetingNew 'active cookie' helps protect Internet users from cyber crooks A new technique developed by Indiana University cybersecurity expert Markus Jakobsson provides a strong shield against identity theft and cyber attacks. His "active cookie" is designed to protect against scams involving domain spoofing. Such attacks "poison" a domain name server by planting false information in it, causing a user's request to be redirected elsewhere while telling the user they are at the correct Web site. Jakobsson believes active cookies can provide protection from such attacks. Contact: Joe Stuteville

2006 AAAS Annual MeetingVirtual playmates help real children with language Can "virtual" playmates -- what the Northwestern University researcher who created them calls "embodied conversational agents" -- help "real world" children develop language and literacy skills? A Northwestern researcher explains how virtual peers listen to, interact with, interrupt, and tell stories to real-life children and enhance children's emergent literacy.

2006 AAAS Annual MeetingStudent group develops grassroots effort to create science policy dialogue What began as a small group of University of Washington students organizing a public forum on a controversial science policy question has since grown into an organization that is fostering dialogue between scientists, the public, and political leaders. Their project has created a forum for discussion of science, ethics, and public policy, and their success holds lessons for other students interested in organizing similar grassroots groups.
