Emulating stingray movement to build next generation of submarines
Stingrays swim through water with such ease that researchers believe that emulating the fish’s unique way of swimming could improve deep-sea vehicles’ agility and fuel efficiency. “Most fish wag their tails to swim. A stingray’s swimming is much more unique, like a flag in the wind,” says one researcher.

Insects’ way of flying inspires design of tiny flying robots
Researchers have identified some of the underlying physics that may explain how insects can so quickly recover from a stall in midflight — unlike conventional fixed wing aircraft, where a stalled state often leads to a crash landing. The analysis improves the understanding of how insects fly and informs the design of small flying robots built for intelligence gathering, surveillance, search-and-rescue, and other purposes.

Chevron contributes $1.5 million to new engineering education initiative
Chevron has contributed $1.5 million to a new National Academy of Engineering (NAE) initiative that will provide expert, research-based guidance to those involved in overseeing engineering education in kindergarten through grade 12. The initiative will create a clearinghouse of curriculum materials and resources and connect engineering education experts with teachers, administrators, and others involved in providing engineering experiences to K-12 students.

Philippines prepares for worse disasters to come
On average, the Philippines experiences about twenty typhoons a year, including three super-typhoons and many incidents of flooding, drought, earthquakes, tremors, and occasional volcanic eruptions, making the country one of the most naturally disaster-prone areas in the world. Filipino government agencies, with the help of international disaster and relief agencies, have created new strategies for disaster preparedness, response, and mitigation which may well have potential applications in other parts of the world. As the impact of climate change grows more pronounced, the Philippines is becoming a hothouse for developing new methods and systems in the growing business of disaster relief.

Advanced police surveillance technologies pose significant privacy concerns
Much of the attention on surveillance in the media focuses on the National Security Agency (NSA), but there is not a lot of scrutiny on local domestic surveillance. In 1997, about 20 percent of police departments in the United States used some type of technological surveillance. By 2007, that number had risen to more than 70 percent of departments. Experts in criminal law and information privacy warn that the widespread use of advanced surveillance technologies such as automatic license plate readers, surveillance cameras, red light cameras, and facial recognition software by state and local police departments, combined with a lack of oversight and regulation, have the potential to develop into a form of widespread community surveillance, which ought to pose significant privacy concerns to law-abiding citizens.

Sunlight-activated nanogrid breaks down pollutants in water
Oil spills do untold damage to the environment — to the waters they pollute and to marine and other wildlife. The Deepwater Horizon spill in the Gulf of Mexico in 2010, for example, the largest accidental marine oil spill in the history of the petroleum industry, flowed unabated for three months. Typically, such oil spills are extraordinarily difficult to clean up. Soon, however, the process may become infinitely easier and ecologically friendly, the result of a new invention — “nanogrid” — a large net consisting of metal grids made of a copper tungsten oxide, that, when activated by sunlight, can break down oil from a spill, leaving only biodegradable compounds behind.

U.S. Navy dominates competition for number, quality of patents
The IEEE evaluated more than 5,000 organization patent portfolios, across the seventeen industry sectors evaluated in its scorecard, for the number of patents issued as well as the growth, impact, originality, and general applicability across their respective portfolios. A laser with the potential to jam heat-seeking missiles and sniff out chemicals was one of 358 technologies patented by the U.S. Navy in 2012, helping the service dominate the government category in an annual ranking of patent portfolios published 23 October. It is an achievement the Navy has held since the scorecard added the government category in 2008.

Chelyabinsk meteor explosion a "wake-up call," scientists warn
Three new studies have revealed details of the meteor that exploded above Russian city, Chelyabinsk, in February this year. Their findings provide information about the meteor’s origin, trajectory, power and damage by the airburst (the shock wave that travelled through the air from the explosion). These findings may help to refine theoretical models about the likely frequency of such events, the potential damage they could cause and hazard mitigation strategies needed for planetary protection.

DoD ends ambitious blimp program
The Department of Defensehas decided to end its Long Endurance Multi-Intelligence Vehicle (LEMV) project.The blimp was supposed to fly for as long as three weeks at a time, gather intelligence using 2,500 pounds worth of the most advanced cameras, sensors, and other intelligence technology. Operating at an altitude of 20,000 feet, the airship was designed to withstand enemy fire with its blend of fabrics, including kevlar. The Pentagon spent $297 million on the airship, but last month sold it back to one of the contractors which built it for $301,000.

Wildfire science returns to California’s Rim Fire
The challenging job of managing wildfires rests with other agencies, but the U.S. Geological Survey (USGS) provides the underlying science for sound land management decisions, before, during, and after wildfires. The USGS role studying natural hazards such as floods, landslides, earthquakes, and volcanoes is well known, but fewer people are aware of the USGS scientific work in major wildfire events, which are one of the most regular and sometimes most devastating natural hazards in the West.

War experiences harden group alliances
War is hell, and according to new research, experiencing its horrors can cause people to have a greater affinity for members of their own group, particularly if they are exposed to warfare in early adulthood or later in childhood. The researchers say that these effects have the potential to explain why conflict sometimes leads to cycles of war and sometimes stimulates nation-building in its wake.

Safe long-term CO2 storage possible
Since 2004, the German Research Centre for Geosciences (GFZ) has led an international research network to investigate the geological storage of the greenhouse gas (CCS, for carbon capture and storage). GFZ’s scientists say that their work at the Ketzin site, 40 km west of Berlin, has shown that geological CO2 storage on a pilot scale can be done safely and reliably.

Wireless device converts wasted energy into electric power
Using inexpensive materials configured and tuned to capture microwave signals, researchers have designed a power-harvesting device with efficiency similar to that of modern solar panels. The device wirelessly converts the microwave signal to direct current voltage capable of recharging a cell phone battery or other small electronic device.

Developing robots for bridge inspection, mine rescue with NSF grants
In 2011, at Carnegie Mellon University, President Barack Obama announced the National Robotics Initiative. The National Science Foundation announced it has awarded a total of more than $7 million to Carnegie Mellon researchers in the latest round of grants for the initiative — a multi-agency effort to develop robots that can work with humans to extend and augment human skills. Researchers are developing robots for bridge inspection, mine rescue, and aid for the blind.
