We summarize the week's science breakthroughs every Thursday.
- Tech
Batteries not included
Researchers have developed a sensor that, when flexed, generates enough charge to send wireless signals.
- Tech
New technique spins superlong nanowires
Made from any number of materials, fibers are millionths of a millimeter across and kilometers long.
- Tech
Social Networks
Power networks in Congress, Twitter’s crystal ball and iPhone contagion in news from an MIT workshop on information in social media.
- Tech
Information flow can reveal dirty deeds
An analysis of Enron e-mails reveals that corrupt networks have a distinctive shape.

Nuclear energy: As Germany goes…
The German government surprised many energy analysts May 30, with its pledge to phase out use of nuclear power. What makes the announcement particularly noteworthy is that this government is not offering to walk away from a bit player. Nuclear power currently supplies almost one-quarter of that nation’s electrical energy — more than its share in the United States.

Cans bring BPA to dinner, FDA confirms
Federal chemists have confirmed what everyone had expected: that if a bisphenol-A-based resin is used to line most food cans, there’s a high likelihood the contents of those cans will contain at least traces of BPA.

Fishy fat from soy is headed for U.S. dinner tables
Most people have heard about omega-3 fatty acids, the primary constituents of fish oil. Stearidonic acid, one of those omega-3s, is hardly a household term. But it should become one, researchers argued this week at the 2011 Experimental Biology meeting.

U.S. network detects Fukushima plume
Traces of radioactivity attributable to the earthquake-damaged Fukushima reactor complex in Japan have reached the West Coast of the United States.
- Tech
Chernobyl’s lessons for Japan
Radioactive iodine released by the Chernobyl nuclear accident has left a legacy of thyroid cancers among downwinders — one that shows no sign of diminishing. The new data also point to what could be in store if conditions at Japan’s troubled Fukushima Daiichi nuclear-power complex continue to sour.

Radiation: Japan’s third crisis
As if the magnitude-9 earthquake on March 11 and killer tsunami weren’t enough, a new round of aftershocks — psychological ones over fear of radiation — are rocking Japan and its neighbors.
