Without water reform Asia will face food shortage by 2050
There are three options for meeting the food needs of Asia’s population, which will expand by one-and-a-half billion people over the next forty years: The first is to import large quantities of cereals from other regions; the second to improve and expand rainfed agriculture; and the third to focus on irrigated farmlands

Through the wall, clearly: Radio waves "see" through walls
A network of radio transmitters can track people moving behind solid walls; the system could help police, firefighters, and others nab intruders, and rescue hostages, fire victims, and elderly people who fall in their homes. It also might help retail marketing and border control

iRobot shows morphing blob robot
Massachusetts-based robotics specialist shows a blob robot which moves forward by inflating and deflating, or “jamming”; the jamming techniques allows the robot to transition from a liquid-like to a solid-like state; the goal is to build a robot that can squeeze through tiny openings smaller than its own dimensions, which could be valuable in a variety of military, surveillance, and search-and-rescue missions

China ponders: Are a few big hydropower projects better than many small ones?
China is moving aggressively to build dams along the upper reaches of the Yangtze River, in part to protect the Three Gorges Dam, but can such hydropower development be done better? “It’s not just dams versus no dams,” one expert says; “It’s about elegant dams”

New compartment design protects vehicle crew in battle
By putting the backs of the crew toward the center of the crew compartment, the new design concept moves the crew away from the outside walls to reduce the likelihood of injury from side blasts, provides better visibility for the crew to monitor their surroundings, and allows blast-resistant seats to be frame mounted

Asteroid collision: How to defend Earth, II
Asteroid impacts are much rarer than hurricanes and earthquakes, but they have the potential to do much greater damage; moreover, what if an asteroid hits Earth in the Middle East or the Asian subcontinent? Such an event could be misinterpreted as a nuclear attack — both produce a bright flash, a blast wave, and raging winds; the result may be a nuclear war

The long view
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.
