Sleuthing by Computer

Article Abstract:

Computers are important tools for solving crimes. Computer systems, such as that at the Georgia Crime Information Center, handle and access large volumes of data compiled as evidence for cases. Instruments providing information for these data bases include spectrophotometers, scanning electron microscopes, and chromatographs. Computer processing of fingerprints allows for extensive searches for suspect identification. The technology of the FBI's Automatic Fingerprint Identification System (AIDS) is illustrated and explained. The digitizing of fingerprints is under study. Other technologies under investigation include a voice identification system and a mug-shot tracing system. Photographs and graphs illustrate these technologies.

Nurturing Energy Infants and Orphans

Article Abstract:

The U.S. Department of Energy's Division of Advanced Energy Projects (AEP) has an $8.3 million budget to fund smaller energy projects that no one else otherwise would care about. The division is primarily an applied research program. The areas that get AEP funds are new approaches to fusion power, new sources of electromagnetic radiation, chemical energy conversion, solar energy devices, electromagnetic acceleration, and energy-efficient membranes. A table lists projects funded by AEP.

Biological Effects of Electromagnetic Fields

Article Abstract:

Although research is incomplete, researchers are finding changes in organisms due to irradiation by weak electromagnetic fields. Results in recent work have found magnetic fields to effect chromosomes, nerve and bone cells, immune cells, and developing fetuses. Data from these various experiments are given in photographs, graphs and tables.
