Abstract The average fuel consumption of light vehicles can be reduced several-fold by the use of currently available technology. This conclusion is based on a simple computer model which has been… (More)
Some—but by no means all—of the Chernobyl story can now be told. Soviet scientists have assembled enough information from interviews, plant records and computer simulations to describe the chronology… (More)
The 560 square miles of desert occupied by the Hanford Site in southeastern Washington are strewn with the silent hulks of reactors and processing plants that once produced plutonium for nuclear… (More)
As you cool a conventional superconductor, it acts as a metal until it reaches the critical temperature Tc, below which it rapidly goes superconducting. But some of the high‐temperature, copper oxide… (More)
A stunned physics community is asking whether coauthors, institutions, or referees should have caught the misdeeds at an earlier stage.
Researchers interested in exploring the competition between forces that pair electrons and those that align the atomic spins have found it useful to look at the area around magnetic flux lines… (More)
Researchers report evidence that fusion has occurred within collapsing bubbles of deuterium-containing vapor. Critics would like to see more definitive proof.
If semiconductor quantum‐well lasers are so successful, shouldn't quantum‐wire or quantum‐dot lasers be even better? That's a question that many researchers have set out to answer. Quantum wells… (More)
Until recently, no free‐electron laser was able to convert more than 5% of the energy from an electron beam into microwave radiation. Last fall, however, a team from Lawrence Livermore National… (More)
