L-3's millimeter wave scanning technology tested at ten U.S. airports
Two technologies — backscatter X-rays and millimeter wave — compete in the airport security scanning market; TSA is currently testing millimeter wave at ten airports, and the fact that the technology is faster than its rival may make it the scanning technology of choice

Anti-invisibility cloak would render invisible objects visible again
A perfect invisibility cloak guides rays so effectively that none reaches the cloaked object within, keeping it in total darkness — a disadvantage if invisibility cloaks are ever to be used to shield tanks, steer microwaves in space, or hide humans; scientists find a solution

Scientists use bacteria to pinpoint chloride toxins
Chloride toxins are carcinogens and dangerous to the environment; they may contaminate food, or used to poison people intentionally (as was the case with Ukrainian president Viktor Yuschenko in 2004; the Russian secret service is suspected of trying to kill him); scientists are using the sensor with which bacteria detect chloride compounds to devise an early detection system

The long view
Nuclear Has Changed. Will the U.S. Change with It?
Fueled by artificial intelligence, cloud service providers, and ambitious new climate regulations, U.S. demand for carbon-free electricity is on the rise. In response, analysts and lawmakers are taking a fresh look at a controversial energy source: nuclear power.
Exploring the New Nuclear Energy Landscape
In the last few years, the U.S. has seen a resurgence of interest in nuclear energy and its potential for helping meet the nation’s growing demands for clean electricity and energy security. Meanwhile, nuclear energy technologies themselves have advanced, opening up new possibilities for their use.
