摘要:
As evidence for a liquid‐metal Earth core was beginning to accumulate early in the last century, Joseph Larmor suggested in 1919 that dynamo action of that conducting fluid circulating in Earth's interior might be what sustains the geomagnetic field. But Larmor's idea, which geophysicists now take for granted, lay dormant for the next two decades, even as seismological evidence for a liquid core surrounding a solid iron inner core became ever more detailed.

摘要:
If you drop a spoonful of sour cream into a bowl of borscht, the two liquids will barely mix. But if you stir them, the spoon will drag filaments of cream through the soup. Stir further, and the filaments will stretch and fold. Eventually, if that's your taste, the cream and soup will blend.

摘要:
A dentist in Alexandria, Egypt, seeks a replacement for decaying bone. To that end, a sol–gel chemist in Lisbon, Portugal, is working to create glass structures with continuous porosity that would let cells and nanofibers grow and nutrients flow. The structures will be characterized by scientists at Lehigh University in Bethlehem, Pennsylvania, and the interface between the candidate bone replacement and biological tissue will be investigated in Senegal and at Princeton University.

摘要:
Some two dozen power plants are scheduled to be built or refurbished during the next five years in Canada, China, several European Union countries, India, Iran, Pakistan, Russia, and South Africa. In the US and the UK, governmental preparations are under way that may lead to 15 new reactor orders by 2007.

摘要:
To better understand and anticipate what one researcher calls the “risk, hope, hype, and fear” of nanotechnology, NSF is funding two new centers and two related projects to create a four‐university network that will study the “societal implications” of the rapidly expanding field of science. The five‐year grants, which total $14.3 million, will fund the sixth major NSF nanotechnology research network and add yet another piece to the $1 billion‐per‐year US National Nanotechnology Initiative.

摘要:
As the rest of the US government's fiscal year 2006 budget was being finalized by Congress in November and December, the Department of Defense budget was mired in congressional fights over a host of provisions that had little or nothing to do with defense—oil drilling in the Arctic, a ban on torture, hurricane relief, and preparations for a bird‐flu pandemic. And although Congress added $50 billion to the defense authorization for the wars in Iraq and Afghanistan, the Bush administration is expected to continue funding the conflicts through multi‐billion‐dollar supplemental requests outside the regular budget process.

摘要:
When Norman Augustine, the former chairman of Lockheed Martin Corp, oversaw the 10‐week effort to put together the US National Academy of Sciences' “Gathering Storm” report, he was worried that the broad scope of the report's four recommendations and the high cost of implementing them could doom the study to gather dust like so many reports before it. The report, which calls for spending several billion dollars to rejuvenate US science and research, “is sailing into a headwind,” Augustine said in October (see PHYSICSTODAY, December 2005, page 25).
