House bill allows Border Patrol to ignore environmental, safety protections along borders
The House of Representatives passed a sweeping bill which would allow the Border Patrol to ignore dozens of environmental protection laws — among them the Wilderness Act and Endangered Species Act — on all federally managed land within 100 miles of the Mexico and Canada borders; supporters argue that the measure is necessary to give the border patrol more freedom to chase illegal immigrants and drug smugglers; critics charge that the measure has little, if anything, to do with border security, and more to do with opening federally managed land to exploitation by private businesses, or pandering to local political constituencies

Carbon capture and storage likely to cause earthquakes
Carbon capture and storage, or CCS, is a major component of the world’s greenhouse gas reduction strategy; to make a significant contribution to emission reduction, however, CCS would need to operate on a massive scale, potentially sequestering upward of 3.5 billion metric tons of CO2 each year; researchers say that the injection of massive quantities of CO2 would be likely to induce small temblors which would break the reservoirs’ seals and release the stored CO2 into the atmosphere

Do nano-pesticides hold promise or pose threat to greener agriculture?
Nanotechnology has developed significantly in the past decade and was able to create many new materials with a vast range of potential applications; the risk that nano-particles may pose to human and environment health, however, is not yet fully understood; a precautionary principle suggests keeping environmental release of nano-particles minimal until their fate and toxicity is better understood

Exploring the Bermuda Triangle's swirling vortices
Researchers, funded by the Office of Naval Research, deployed twenty-one underwater probes to study vortices at the Bermuda Triangle; a vortex is a swirl of water that can be created in several ways, including water being pushed between land masses and then released into the open ocean; the oceanographers did well to lose only one of the underwater probes, considering they were studying the notorious Triangle

3-in-1 water monitoring system
All water treatment plants using membrane technology are required to be able to perform three processes to comply with international standards: identify whether there are any bacteria or contaminants; detect any broken membrane filters in the treatment plant; and pinpoint which filter is broken — accurate to 1 in 100,000 filters; a new, innovative device performs all three processes

For safer offshore drilling, government should modify monitoring practices
Since the April 2010 Deepwater Horizon blowout and explosion, the federal government as well as the offshore oil and gas industry have been undergoing major changes, including the issuance of regulations requiring operators of offshore facilities to adopt and implement comprehensive Safety and Environmental Management System (SEMS) programs by 15 November 2011

Nuclear waste repositories in suburbia?
Finding sites for nuclear waste storage is a growing problem, with decision makers running into the “not in my back yard” problem; the demise of Nevada’s Yucca Mountain project is but the latest example; researchers find that acceptance of sites for spent nuclear fuel repository may well depend on gender and economic background: in Finland, at least, affluent men more often are more receptive to the idea of locating such facilities near their neighborhoods than women or disadvantaged people

Automated pavement crack detection and sealing system to extend roadways life
Researchers from the Georgia Tech Research Institute developed a prototype automated pavement crack detection and sealing system; in road tests, the system was able to detect cracks smaller than one-eighth-inch wide and efficiently fill cracks from a vehicle moving at a speed of three miles per hour

New method uses gunshot residue to determine caliber, type of weapon used in crime
Researchers have developed a method to determine the caliber and type of weapon used in a crime by analyzing gunshot residue (GSR); using near-infrared (NIR) Raman microspectroscopy and advanced statistics, the new technique may play a pivotal role in law enforcement cases and forensic investigations

Belief in hell associated with reduced crime
A broad study, study following143,197 people in sixty-seven countries over twenty-six years, found that criminal activity is higher in societies in which people’s religious beliefs contain a strong punitive component than in places where religious beliefs are more benevolent; a country where many more people believe in heaven than in hell is likely to have a much higher crime rate than one where these beliefs are about equal

Seabed carpet could harness wave energy
A synthetic “seabed carpet” that mimics the wave-damping effect of a muddy seafloor could be used to extract energy from waves passing over it. As well as offering a new way to produce clean and cheap electricity, the carpet — which has not yet been built — could be used to protect coastal areas against strong waves and provide areas of safe haven for boats in stormy seas

Knowledge of fractions and long division predicts long-term math success
From factory workers to Wall Street bankers, a reasonable proficiency in math is a crucial requirement for most well-paying jobs in a modern economy; yet, over the past thirty years, mathematics achievement of U.S. high school students has remained stagnant — and significantly behind many other countries, including China, Japan, Finland, the Netherlands, and Canada; a new study has identified a major source of the gap — U. S. students’ inadequate knowledge of fractions and division

Key to U.S. future prosperity: world-class research universities
American research universities are essential for U.S. prosperity and security, but the institutions are in danger of serious decline unless the federal government, states, and industry take action to ensure adequate, stable funding in the next decade, says a new report by the National Research Council; “The talent, innovative ideas, and new technologies produced by U.S. research universities have led to some of our finest national achievements, from the modern agricultural revolution to the accessibility of the World Wide Web,” says the chairman of the committee that wrote the report

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.
