World's largest airship inflated Wednesday for the first time
The world’s largest airship — 235 feet long and 65 feet in diameter — was inflated on Wednesday for the first time; the test took place inside the Garrett Coliseum in Montgomery, Alabama which, the proprietors state, can hold as many as 1,500 cattle (“with milking parlor”); the airship features many innovations, including propelling ducted fans which are mounted along the centerline of the hull rather than beneath it, so that the nose does not lift when more power is applied

DARPA looking for automated insider threat spotter
The U.S. National Counterintelligence Strategy asserts that “Trusted insiders — are targeting the US information infrastructure for exploitation, disruption, and potential destruction”; DARPA, the Pentagon research arm, is soliciting idea for technology which will automatically spot — and eliminate — insider threat to U.S. information infrastructure

The day of transportable, refrigerator-size nuclear reactor nears
The need for more energy and the growing interest in energy not based on fossil material have led to a revival of interest in nuclear power; there is a competition afoot among several companies for designing and building — and receiving a operation license for — a refrigerator-size nuclear reactor; the $50 million, 25-megawatt unit is transportable by truck, and would put electricity into 20,000 homes

Cigarette butts may be used to prevent corrosion of oil pipes
Cigarettes butts are so toxic, they kill fish; still, 4.5 trillion cigarette butts find their way into the environment each year; Chinese scientists find that chemical extracts from cigarette butts be used to protect steel pipes from rusting; rust prevention and treatment cost the oil industry millions of dollars annually

Wisconsin researcher punished for unauthorized research on bioterror agent
A university of Wisconsin researchers conducted unauthorized research on bioterror agent; the researcher developed antibiotic-resistant variants of brucellosis and tested them on mice; the University of Wisconsin was fined $40,000 by the National Institutes of Health, and the professor was ordered to stay out of a lab for five years

Tiny sensors embedded in cell phones identify, map airborne toxins in real time
Cell phones are everywhere people are, so University of California-San Diego’s researchers want to turn the devices into chemical sensors; the tiny sensor, a porous flake of silicon, changes color when it interacts with specific chemicals. By manipulating the shape of the pores, the researchers can tune individual spots on the silicon flake to respond to specific chemical traits

New detection technology identifies bacteria, viruses, other organisms within 24 hours
In the area of biodefense, current systems are centered on the detection of smaller prioritized sets of high-risk pathogens, rather than testing for a much broader spectrum of organisms; a new detection method from Lawrence Livermore allows not only the identification of the biological pathogens on a priority screening list, but also any other already-sequenced bacteria or virus in a sample that first responders, doctors, or regulatory agencies might not have been expecting to find, including possible novel or emerging pathogens

Cobham develops more accurate, cost-effective landmine detector
The Red Cross estimates that 60-100 million mines are in place in 62 countries, causing 800 deaths each month; clearing mines is an expensive proposition, averaging £1m/km2; much of this cost is owed to high number of false alarms from metal detectors; British company develops a dual-sensor mine detector that enables nearly 33 percent more land to be cleared within existing budgets

New method to develop latent fingerprints
Most of the techniques currently used for developing fingerprints rely on the chemistry of the print, but as prints dry or age, the common techniques used to develop latent fingerprints, such as dusting or cyanoacrylate — SuperGlue — fuming often fail; Penn State professor says that using the physical properties of the fingerprint, not the chemistry of the substances left behind, would solve these problems

Sensors emulate insects' acoustic capabilities
Researchers build sensors emulating the way a mosquito senses an oncoming predator or the swat of a human hand; these sensors have the potential to improve the industrial use of acoustic sensors and actuators, from medical ultrasound imaging, non-destructive testing of materials, and even robot guidance

Drive-by sniffing out of homemade bomb factories
Terrorists may not be safe for long — stealthily developing home-made explosives in their bath tubs; Swedish researchers are working on developing an explosive detection systems to be mounted atop police vehicles; the system would effectively monitor urban areas for possible bomb-making activities while on normal patrol; the system’s sensors would detect elevated levels of suspicious substances and then use integrated GPS technology to record the time and location the molecules are being emitted from

New video camera offers very high resolution from afar -- and up close
A new, 360° surveillance video promises high-resolution detail, multiple views, and DVR features; coverage this sweeping, with detail this fine, requires a very high pixel count; the new camera has a resolution capability of 100 megapixels — this is as detailed as fifty full-HDTV movies playing at once, with optical detail to spare

Remotely controlled robot inspects dangerous structures
A remotely controlled robot uses laser sensors to look inside damaged structures to look for survivors; when inside the structure, the robot takes multiple scans using Light Detection and Ranging (LIDAR) unit that takes up to 500,000 point measurements per second. It also can scan through walls and windows

Non-toxic cleaners for terrorist attacks
Traditional chlorine- and lye-based cleaning agents are potentially hazardous and can react with chemical weapons and other materials in the environment to form new toxic substances; military researchers non-toxic, ultra-strength cleaners that could be used in the aftermath of a terrorist attack; the peroxide-based “green” decontaminants are tough enough to get rid of nerve gas, mustard gas, radioactive isotopes, and anthrax

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.
