Raytheon launches MathAlive! to encourage math, science education
Results of a new survey of America’s middle school students show that nearly half of students aged 10-14 enjoy learning math outside of school and consider hands-on activities their favorite method for experiencing new subject material; Raytheon launches MathAlive! to encourage students to study math, science, and engineering

Computer spots liars by looking at the way they talk
Computer scientists are exploring whether machines can read the visual cues of an individual’s conduct to discover whether or not that individual is lying; in a study of forty videotaped conversations, an automated system the researchers developed correctly identified whether interview subjects were lying or telling the truth 82.5 percent of the time

Robot for shipboard firefighting
In both war and peace, fire in the shipboard environment is serious and frequently results in excessive damage and high repair costs because the fire is not detected or controlled adequately; researchershave developed a humanoid robot that could fight fires on the next generation of combatants

National Academies calls for expanded nuclear-fusion research
A report out on Wednesday from the National Academies says university researchers studying nuclear fusion still have a long way to go before overcoming the many scientific hurdles to the commercial generation of what is hoped to be a virtually limitless supply of energy

Shift to green energy could mean crunch in rare Earth metals supply
A large-scale shift from coal-fired electric power plants and gasoline-fueled cars to wind turbines and electric vehicles could increase demand for two already-scarce metals — available almost exclusively in China — by 600-2,600 percent over the next twenty-five years

Balancing safety, risk in the debate over the new H5N1 viruses
This fall, the U.S. National Science Advisory Board for Biosecurity (NSABB) set off a debate when it asked the authors of two recent H5N1 research studies and the scientific journals that planned to publish them to withhold important details of the research in the interest of biosecurity; the scientific community is divided over the issue of best to balance free research and security

If Japan-like disaster happened in U.S., results would be far worse
An estimated 20,000 people died or are still missing after a massive earthquake-induced tsunami struck Japan on 11 March 2011, yet some 200,000 people were in the inundation zone at the time; experts say that if the same magnitude earthquake and tsunami hits the Pacific Northwest, the death toll will be much higher because of the lack of comparable preparation; that 90 percent rate could be the number of victims, not survivors

Industry: current chemical safety standards sufficient, should be extended
DHS’s management of the U.S. chemical plant safety has come under criticism lately, but he Society of Chemical Manufactures and Affiliates (SOCMA) said it strongly supports U.S. chemical security standards; the industry associated noted that since the program’s 2007 launch, more than 2,000 facilities have changed processes or inventories such that they are no longer considered high-risk under the Chemical Facility Anti-Terrorism Standards (CFATS)

Solving the major problem of renewable energy: intermittency
Intermittency, sometimes called the Achilles’ heel of renewable energy, has so far limited the penetration of renewable sources in most power grids; engineers imagine an energy future where giant transmission grids are backed up by massive energy storage units

National Weather Service budget cuts threaten poor IT infrastructure
The Obama administration has proposed cutting more than $39 million from the National Weather Service’s (NWS) budget, particularly from its IT department, and critics worry that the cuts could cause the agency’s already crippling infrastructure problems to grow worse

Increase in groundwater demands due to climate change
As precipitation becomes less frequent due to climate change, lake and reservoir levels will drop and people will increasingly turn to groundwater for agricultural, industrial, and drinking water needs; the resource accounts for nearly half of all drinking water worldwide, but recharges at a much slower rate than aboveground water sources and in many cases is nonrenewable

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.
