Simulating supernovae on supercomputers
Multidimensional simulations of core-collapse supernovae will answer important questions about the creation and dissemination of elements that make life possible. They may also be important in the development of “enabling technologies” for other applications, such as combustion, climate, fusion, stockpile stewardship, and nuclear medicine.

New ceramic membranes may help hydrogen replace gasoline as auto fuel
If hydrogen fuel cells are ever to replace gasoline engines in cars, they will need a cheap source of high-purity hydrogen -- and Argonne technology could provide one. Argonne's Energy Technology Division has developed a ceramic membrane that can extract hydrogen from methane, the chief component of natural gas.

Bright future for tactical laser weapons
In a demonstration at the White Sands Missile Range in New Mexico, the solid-state heat-capacity laser (SSHCL) burned a 1-centimeter-diameter hole straight through a 2-centimeter-thick stack of steel samples in 6 seconds. The electrical current to do so came from a wall outlet and cost no more than 30 cents. While large chemical lasers have successfully shot down tactical rockets, the SSHCL design supports the weight and size requirements for a future mobile deployment.

DOE kicks off 'deep trek' to develop deeper, smarter drilling technology
Initiative Will Develop "Smart" Drilling System for Deep Gas To meet the Nation's growing demand for natural gas, drillers will likely have to probe deeper into more hostile formations to find new gas supplies. To develop a new high-tech "smart" drilling system that can tap into deep reservoirs, the Department of Energy is beginning "Deep Trek." A solicitation is now available to developers who are interested in proposing "Deep Trek" drilling and completion concepts.

A new generation of supercomputers
Using paper and pencil, theorists have captured new ideas, revealed intricate mathematical relations and carried out page-long calculations. But times have changed. For many applications, physicists now prefer to attack their models and equations with the best computers available. The Fermilab theory group became one of the top players in the area of computational physics with the installation of a supercomputer called ACPMAPS in 1989.
