A collaboration led by scientists at the U.S. Department of Energys Brookhaven National Laboratory has revealed a new mechanism that explains why adding calcium to a high-temperature superconductor increases its current-carrying capacity. The findings refute the current explanation and open the door for similar additives with potentially better current-boosting abilities.

A battery with a lifespan measured in decades is in development at the University of Rochester, as scientists demonstrate a new fabrication method that in its roughest form is already 10 times more efficient than current nuclear batteries - and has the potential to be nearly 200 times more efficient. The details of the technology, already licensed to BetaBatt Inc., appears in todays issue of Advanced Materials.

In a challenge to conventional wisdom, scientists have found that buckyballs dissolve in water and could have a negative impact on soil bacteria. The findings raise new questions about how the nanoparticles might behave in the environment and how they should be regulated, according to a report scheduled to appear in the June 1 print issue of the American Chemical Society's peer-reviewed journal Environmental Science & Technology. ACS is the world's largest scientific society.
