Vaporware Phantom Haunts Us All
Last year was a vintage year for vaporware. Not only did lots of promised products fail to materialize in 2004, but several companies also made repeat appearances on our annual roll call of shame. By Leander Kahney. Researchers Discover New Function Of Cardiac Sodium Pump
Scientists at the Max Delbrück Center for Molecular Medicine Berlin-Buch have discovered a new function of the cardiac sodium pump. During embryonic heart morphogenesis, the pump generates a change in the ion concentration within and outside the cells (ion gradient). The scientists were able to demonstrate that the ion gradient determines the top (apical) and bottom (basal) of heart cell surfaces. Scientists call this cell polarity, a phenomenon vital for heart function. What's That Stuff?: Process Cheese
Explains the differences between various types of processed cheese products, such as pasteurized process cheese spread and imitation cheese. Discusses specific brands (such as Velveeta and Cheez Whiz), regulations for processed cheese products, the production process, and related topics.

The Aznalcóllar mining accident more than 11 years ago, which contaminated part of the Doñana National Park, also damaged reptile habitat there. Now a team of Spanish researchers, who have been studying the reptile community since 2000, have shown, by setting up artificial refuges, that the disappearance of natural refuges had a serious impact on lizard and snake numbers. Rare Hawaiian monk seal brought to marine lab for study and treatment
A young Hawaiian monk seal that was removed from the wild last year for treatment and rehabilitation is providing researchers with a rare opportunity to study the physiology of this critically endangered species. Washington's Comprehensive Wildlife Conservation Strategy

Cassini's nose dives through Saturn's E ring have yielded insights on the give and take of ice particles between Enceladus and the ring. Some of the moon's jets are successful in shooting ice grains far enough to become part of the E ring. But even the ice grains that make it to the E ring tend to be recaptured by Enceladus within a few orbits as the moon moves around Saturn. 'Best Practices' For Handling Nanomaterials In The Workplace
The International Council on Nanotechnology (ICON) has issued a comprehensive review of existing efforts to develop "best practices"for handling nanomaterials in the workplace. The report was prepared by researchers at the University of California, Santa Barbara as part of a two-phase project to catalogue how industry is managing the potential occupational safety risks posed by nanomaterials. ICON is a coalition of academic, industrial, governmental and civil society organizations. Retinal Scans Eyed For New Mexico Show Cattle
It sounds like science fiction, but New Mexico State University researchers are testing advanced eye-scanning technology on cattle as part of a national tracking system for animal health. Presidents of the United States: Selected Images From the Collections
