Children’s learning to spell, read aided by pattern recognition, use
Rebecca Treiman says the “i before e” rule is just the tip of the iceberg when it comes to spelling patterns found in the English language.
Human Genome Project is complete
Researchers at Washington University School of Medicine in St. Louis and other members of the International Human Genome Consortium announced the successful completion of the Human Genome Project more than two years ahead of schedule. By completing the Human Genome Project, researchers believe they are launching a new age of discovery that will transform human health. Knowing the order of the genetic building blocks — commonly abbreviated A, T, C and G (adenine, thymine, cytosine and guanine) — should allow scientists to learn more about human development and disorders such as heart disease, psychiatric illness and cancer. Already the genome sequencing effort has helped spur discoveries about breast cancer, colon cancer, prostate cancer, cystic fibrosis, Huntington’s disease, Parkinson’s disease and sickle cell disease.

An air pollution expert at Washington University in St. Louis says the air pollution created by the Iraqi war is regional and should remain that way
This NASA image shows the smoke from Iraq’s oil fires set early in the confrontation.An air pollution expert at Washington University in St. Louis says the air pollution created by the Iraqi war is regional and should remain that way unless something catastrophic happens such as the torching of the Kuwaiti oil wells in the 1991 Gulf War.
System considered that links video camera with automatic target recognition
The St. Louis arch has been thought to be a potential target for terrorists.Researchers at Washington University’s Center for Security Technologies are planning a surveillance system that recognizes aberrant traffic flow and then, using automatic target recognition, identifies and analyzes the danger.
Blind and visually impaired Web users offered taste of multimedia future
A still from *Having a Ball*, one of three circus-themed e-cards by Kristine Ng.For the estimated 7 to10 million blind and visually impaired Americans, the Internet has proven to be the most powerful — and most empowering — tool since Braille. Widely available software programs such as JAWS for Windows and Windows-Eyes can read aloud online newspapers and magazines and other previously inaccessible materials. Yet as bandwidth and memory improve, businesses have increasingly sought to drive customers to glitzy, graphics-heavy Web sites that are more difficult, if not impossible, for blind users to navigate. Thanks to a group of senior design students at Washington University in St. Louis, blind and visually impaired Web users can now experience some of the Internet’s increasingly expansive potential. The 23 students — design, illustration and advertising majors in the School of Art — have created some of the first Web sites showcasing new accessibility components of Macromedia Flash MX, the increasingly popular authoring tool for Web interfaces, interactive video, Web-based games, streaming music and other multimedia content.
