E-beam technology to keep food supply safe
More than two million people a year, most of them children, die from food-borne or water-borne illness; more than one-third, or 1.3 billion tons, of the food produced for human consumption every year is wasted or lost because of spoilage; the UN nuclear weapons watch dog, the IAEA, says that irradiating food is a more effective solution for preventing death, illness, and food spoilage than techniques currently in use: heating, refrigerating, freezing, or chemical treatment

U.S. Navy experience shows climate alterations
The U.S. Navy reports that because of its worldwide presence, it sees the effects of climate change directly; and expert tells a scientific audience at Sandia Lab that disparities in current climate science projections “mean that the Navy should plan for a range of contingencies, given our limited ability to predict abrupt change or tipping points for potentially irreversible change”

Water scarcity in California's Bay-Delta necessitates “hard decisions”
Simultaneously attaining a reliable water supply for California and protecting and rehabilitating its Bay-Delta ecosystem cannot be realized until better planning can identify how trade-offs between these two goals will be managed when water is limited

Containing a tunnel flood with an inflatable giant plug
Researchers have developed a giant plug to contain tunnel floods; the plug inflates (with water or air) to dimensions of roughly 32-feet-long and by 16-feet-wide, and holds 35,000 gallons, about the same capacity as a medium-sized backyard swimming pool

Some flame retardants make fires more lethal
Almost 10,000 deaths from fires occur in industrialized countries worldwide each year, including about 3,500 in the United States; scientists find that widely used flame retardants added to carpets, furniture upholstery, plastics, crib mattresses, car, and airline seats and other products to suppress the visible flames in fires are actually increasing the danger of invisible toxic gases that are the No. 1 cause of death in fires

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.
Falling Space Debris: How High Is the Risk I'll Get Hit?
An International Space Station battery fell back to Earth and, luckily, splashed down harmlessly in the Atlantic. Should we have worried? Space debris reenters our atmosphere every week.
Testing Cutting-Edge Counter-Drone Technology
Drones have many positive applications, bad actors can use them for nefarious purposes. Two recent field demonstrations brought government, academia, and industry together to evaluate innovative counter-unmanned aircraft systems.
Strengthening the Grid’s ‘Backbone’ with Hydropower
Argonne-led studies investigate how hydropower could help add more clean energy to the grid, how it generates value as grids add more renewable energy, and how liner technology can improve hydropower efficiency.
