Generating fuel from sunlight
Researchers have made significant progress towards developing a process of Artificial Photosynthesis (AP) that could replace the use of fossil fuels in the future. AP is the industrial process of preparing fuels and chemicals from nothing more than carbon dioxide, water and sunlight. It is a vital process that would be the foundation of a world that would no longer need fossil fuels.

Cockroach cyborgs use microphones to detect, trace sounds in collapsed buildings
Researchers have developed technology that allows cyborg cockroaches, or biobots, to pick up sounds with small microphones and seek out the source of the sound. The technology is designed to help emergency personnel find and rescue survivors in the aftermath of a disaster. The researchers have also developed technology that can be used as an “invisible fence” to keep the biobots in the disaster area. “In a collapsed building, sound is the best way to find survivors,” says one of the researchers.

Mental-health apps may reduce number of mass shooting events
Between 1982 and 2011, mass shootings occurred every 200 days on average. S since 2011, mass shootings have occurred every sixty-four days on average. Mass shootings have one thing in common: the culprits all suffered from mental illness and the condition was known to at least one person. New mobile app educates the public about mental illness and provides local and national resources for early intervention and treatment.

Sandia Lab’s mobile neutron imager shines in urban emergency response exercise
A nuclear device has been hidden in a high-rise building in a major metropolitan area. Emergency responders have intelligence that narrows down the location to a single city block, but it is not safe to search door-to-door. Can they identify the exact location of the device quickly without the culprits realizing a search is on? The answer is a definite yes. Sandia Lab’ mobile imager of neutrons for emergency responders (MINER) system did just that at an emergency response exercise in downtown Chicago earlier this year. The exercise used a sealed laboratory radiation source that mimics the radioactive signature of more nefarious material.

Students point to future of ocean robotics in new global game
College students from around the world demonstrated they could have a hand in shaping the future of ocean robotics as they competed in the first Maritime RobotX Challenge, which was held 24-26 October in Singapore. “Developing autonomy for surface vessels is still in its early stages, and these students have the opportunity to come up with solutions that could set new standards in this field,” said Assistant Chief of Naval Research Capt. Rob Palisin, who helped judge the competition. “In turn, the Navy gets the chance to observe the best young engineers in action and learn from their approaches.”

Next-generation technology for first responders: intuitive, instinctive, and interoperable
DHS’s Science and Technology Directorate (S&T) has a vision for a new age of first responders, a vision which will enable first responders and their technology to be more intuitive, instinctive, and interoperable.TheNext-Generation First Responder suit will incorporates wearables, the Internet, and cellular connectivity, along with multiple environmental and biological sensors to help firefighters, law enforcement, and aid workers, better perform their jobs safely.

Light frequencies help sniff out deadly materials from a distance
Spectroscopic chemical sensing, which measures the frequency of light absorbed or scattered from a substance to help determine its molecular identity, can be used to detect traces of biological and chemical agents and residue from explosive materials. New program aims to develop chip-sized, optical frequency combs which accurately identify even tiny traces of dangerous biological and chemical substances several football fields away.

Building a better lie detector
The Intelligence Advanced Research Projects Activity (IARPA), within the Office of the Director of National Intelligence (ODNI), announced the other day the winner of its first public challenge contest, Investigating Novel Statistical Techniques to Identify Neurophysiological Correlates of Trustworthiness (INSTINCT). The winning solution, JEDI MIND — Joint Estimation of Deception Intent via Multisource Integration of Neuropsychological Discriminators — uses a combination of innovative statistical techniques to improve predictions approximately 15 percent over the baseline analysis.

Fusion reactor concept could be cheaper than coal
Fusion energy almost sounds too good to be true — zero greenhouse gas emissions, no long-lived radioactive waste, a nearly unlimited fuel supply. Perhaps the biggest roadblock to adopting fusion energy is that the economics have not penciled out. Fusion power designs aren’t cheap enough to outperform systems that use fossil fuels such as coal and natural gas. University of Washington engineers hope to change that. They have designed a concept for a fusion reactor that, when scaled up to the size of a large electrical power plant, would rival costs for a new coal-fired plant with similar electrical output.

Sensor network will track down illegal bomb-making
Terrorists can manufacture bombs with relative ease, few aids, and easily accessible materials such as synthetic fertilizer. Security forces do not always succeed in preventing the attacks and tracking down illegal workshops in time. Bomb manufacturing, however, leaves its traces. A network of different sensors will detect illicit production of explosives and improvised explosive devices (IEDs). Traces on doorknobs, in sewage, or in the air will be detected by the sensors and the data will be fused in a command center.

Blackout? Robots can help
Big disasters almost always result in big power failures. Not only do they take down the TV and fridge, they also wreak havoc with key infrastructure like cell towers. That can delay search and rescue operations at a time when minutes count. Now, researchers have developed a tabletop model of a robot team that can bring power to places that need it the most. In addition to disaster recovery, their autonomous power distribution system could have military uses, particularly for Special Forces on covert missions.

Turning mobile phones into detectors of disease-spreading insects
Insects transmit many of the world’s most infectious diseases, but there has been a decline in the expertise needed to recognize species of insects most likely to transmit illness to people. In a new effort to safeguard human populations, a team of scientists, computer programmers, public health officials, and artists is working to enable mobile phones to link up to computers that automatically identify species of disease-carrying insects.

Cheap, easy-to-install water purifying system for remote communities
About 1.5 million people — and 90 percent of them children — die every year from consuming untreated or contaminated water. University of Adelaide mechanical engineering students and staff have designed a low-cost and easily made drinking water treatment system suitable for remote communities in Papua New Guinea (PNG) — using foil chip packets and some glass tubing.
