Smart bricks could monitor buildings, save lives

A “smart brick” developed by scientists at the University of Illinois at Urbana-Champaign could monitor a building’s health and save lives. “This innovation could change the face of the construction industry,” said Chang Liu, a professor of electrical and computer engineering at Illinois. “We are living with more and more smart electronics all around us, but we still live and work in fairly dumb buildings. By making our buildings smarter, we can improve both our comfort and safety.”

Should Memphis Build for California Style Earthquakes?

The federal government is urging Memphis and other parts of the Midwest to adopt a new building code that would make buildings as earthquake resistant as those in southern California, where shaking is much more likely to seriously damage a building. A new study by researchers at Northwestern University, the Reaves Firm in Memphis, and Los Alamos National Laboratory finds that the prescribed measures for the Midwest’s New Madrid seismic zone (NMSZ) would cost far more than the damage prevented. The New Madrid seismic zone includes parts of Tennessee, Kentucky, Missouri, Arkansas, Illinois, Indiana, and Mississippi.

New Molecular Self-Assembly Technique May Mimic How Cells Assemble Themselves

Researchers report that they have created tree-like molecules that assemble themselves into precisely structured building blocks of a quarter-million atoms. Such building blocks may be precursors to designing nanostructures for molecular electronics or photonics materials, which “steer” light in the same way computer chips steer electrons.

Gov’t asks public for help in World Trade Center investigation

U.S. government investigators say they need more help from the public and news media in their massive investigation of the September 11 destruction of the World Trade Center towers in New York. Specifically, officials at the U.S. Commerce Department’s National Institute of Standards and Technology want more photographs and videotape that could yield insights into what happened to the collapsed WTC buildings, occupants and first responders.
