WASHINGTON -- The current policy and legal framework regulating use of cyberattack by the United States is ill-formed, undeveloped, and highly uncertain, says a new report from the National Research Council. The United States should establish clear national policy on the use of cyberattack, while also continuing to develop its technological capabilities in this area. The U.S. policy should be informed by open national debate on the technological, policy, legal, and ethical issues of cyberwarfare, said the committee that wrote the report.

The oxymoron stems from the reality of complex social processes. But this complexity is paralyzing educational reform efforts, said Century, director of science education at the University of Chicago's Center for Elementary Mathematics and Science Education.

A comprehensive assessment of the risk factors for preventable deaths in the United States has found that smoking and high blood pressure are responsible for the greatest number of preventable deaths – each accounting for around 1 in 5 deaths in US adults.

Houston is a reflection of where most of America's cities will be in the next 20 years, according to Stephen Klineberg, Rice University sociologist and director of the annual Houston Area Survey.

Klineberg, who has led the study since its inception 28 years ago, said that along with the major immigration capitals of Los Angeles and New York City, and closely following upon Miami, San Francisco and Chicago, Houston is at the forefront of the new diversity that is refashioning the social and political landscape of urban America.
