A new study finds that “off-peak” electricity production and transmission capacity could fuel 84 percent of the country’s 220 million vehicles if they were plug-in hybrid electrics. This is the first review of what the impacts would be of very high market penetrations of PHEVs. Researchers at the Department of Energy’s Pacific Northwest National Laboratory also evaluated the impact of PHEVs, on foreign oil imports, the environment, electric utilities and the consumer.
Small insects that inhabit some of the most remote parts of the United States are sending a strong message about climate change. New research suggests that changes in midge communities in some of these areas provide additional evidence that the globe is indeed getting warmer. Researchers created a history of changing midge communities for six remote mountain lakes in the western United States.
Scientists at the University of Illinois at Urbana-Champaign have again broken their own speed record for the world’s fastest transistor. With a frequency of 845 gigahertz, their latest device is approximately 300 gigahertz faster than transistors built by other research groups, and approaches the goal of a terahertz device.
New findings indicate that the aurora and other near-Earth space weather are driven by the rate at which the Earth’s and sun’s magnetic fields connect, or merge, and not by the solar wind’s electric field as was previously assumed.
Researchers employing some of the world’s most sophisticated weather research equipment recently captured details on winds and other conditions in a rapidly intensifying hurricane. This data will help to advance the understanding of these complex storms.
The Society for Cardiovascular Angiography and Interventions (SCAI) has released recommendations for the prevention of contrast induced nephropathy (CIN) — potentially fatal kidney damage that can occur when a special dye is injected during certain cardiovascular procedures. The consensus document, the first to be written on this topic, appears in the January 2007 issue of Catheterization and Cardiovascular Interventions: Journal of the Society for Cardiovascular Angiography and Interventions.
Even a small-scale, regional nuclear war could produce as many direct fatalities as all of World War II and disrupt the global climate for a decade or more, with environmental effects that could be devastating for everyone on Earth. A team of scientists at Rutgers University, the University of Colorado at Boulder and UCLA conducted rigorous scientific studies reported at an AGU press conference today.

Researchers at the Department of Energy’s Lawrence Berkeley National Laboratory have discovered two molecular pathways that regulate the organization of heterochromatin, the nucleolus, and other features of nuclear architecture that maintain genome stability in the fruit fly Drosophila melanogaster.
MIT engineers have demonstrated a technology that could introduce an important new phase of the microelectronics revolution that has already brought us iPods, laptops and much more.
