Law-enforcement agencies eager for Web-surveillance tools
Private technology firms are pitching software capable of analyzing large swaths of the Internet to local law enforcement looking for ways to stop the next mass shooting or domestic terrorist event before it happens; police departments hope the software will help them detect online information from terrorists, traffickers, pedophiles, and rioters

Coastline erosion due to rise in sea level greater than previously thought
The effects of coastline erosion as a result of rising sea-level rise can be measured by acceptable engineering tools, but such an erosion in the vicinity of inlets, such as river estuaries, has until now been underestimated – and more difficult to calculate; scientists have develop a new model to calculate this more complex erosion, making a valuable contribution to coastal management, planning, and infrastructure protection

Many of the U.S. 20 million manholes are in need of immediate rehabilitation or replacement
The EPA estimates that there are about twenty million manholes in the United States – or one manhole for every 400 feet of pavement on average; many of those manholes are in serious decay or in need of immediate rehabilitation or replacement

MIT expert: “toxic” political discussions limit climate response
In a talk at the Sandia National Lab, an MIT expert says the inability of natural and social scientists to convince political leaders that “we’re spinning a roulette wheel over climate change” puts humanity at “extreme risk,” and that the difficulties in using science to push for mitigation strategies are more political than scientific

As shoe-scanning devices fail, passengers continue to remove their shoes
In the last five years the U.S. government has tested several scanning devices for detecting explosives and other weapons concealed in the shoes of airline passengers; after spending millions of dollars on these devices, TSA has concluded that the detection systems are ineffective; the result: removing shoes at security check points is going to be a part of air travel for the foreseeable future

Trade-offs between water for food and for curbing climate change
Earth’s growing human population needs fresh water for drinking and food production. Fresh water, however, is also needed for the growth of biomass, which acts as a sink of carbon dioxide and thus could help mitigate climate change. Does the Earth have enough freshwater resources to meet these competing demands?

As Hurricane Isaac beats on New Orleans, new infrastructure is holding up
This week, as Hurricane Isaac was threatening to replicate the physical damage that Katrina inflicted, it has become apparent that $14 billion worth of changes and improvements in infrastructure, planning, and emergency response procedures have given the city of New Orleans and the Gulf states the ability to withstand the worst of the storm

Isaac leaves flooding, power outages in its path
Hurricane Isaac lost its Category 1 hurricane status midday Wednesday and was downgraded to a tropical storm, but the severe rains and winds which it brought with it have not let up much; the number of power outages continues to increase as the number of homes and businesses without electricity is now up to 834,000 between Louisiana, Mississippi, Alabama, Florida, Texas, and Arkansas, with over one-third of the outages in Louisiana alone

Drones being used to track hurricanes
Federal hurricane trackers will start experimenting with unmanned boats and aircrafts to learn more about how to anticipate and track the movements of hurricanes; NASAand the National Oceanic and Atmospheric Administration(NOAA) are teaming up and using a pair of military-surplus Global Hawk spy drones, which are known more for spying on battlefields than chasing storms

Industry fights Pentagon efforts to restrict exporting of infrared products
The global market for infrared technology products will be worth about $2.6 billion dollars by 2017; the technology can be used for commercial products such as automotive, surveillance, and security industries – and is heavily used by the military; three major U.S. infrared equipment makers fight the Pentagon’s efforts to restrict exports of devices based on the technology for fear these devices may enhance the military capabilities of adversaries of the United States

Autonomous Vehicle Technology Vulnerable to Road Object Spoofing and Vanishing Attacks
Researchers have demonstrated the potentially hazardous vulnerabilities associated with the technology called LiDAR, or Light Detection and Ranging, many autonomous vehicles use to navigate streets, roads and highways. The researchers have shown how to use lasers to fool LiDAR into “seeing” objects that are not present and missing those that are – deficiencies that can cause unwarranted and unsafe braking or collisions.
Tantalizing Method to Study Cyberdeterrence
Tantalus is unlike most war games because it is experimental instead of experiential — the immersive game differs by overlapping scientific rigor and quantitative assessment methods with the experimental sciences, and experimental war gaming provides insightful data for real-world cyberattacks.
Prototype Self-Service Screening System Unveiled
TSA and DHS S&T unveiled a prototype checkpoint technology, the self-service screening system, at Harry Reid International Airport (LAS) in Las Vegas, NV. The aim is to provide a near self-sufficient passenger screening process while enabling passengers to directly receive on-person alarm information and allow for the passenger self-resolution of those alarms.
