Moth eyes inspire more efficient solar cell design
Moth eyes do not reflect light: They have orderly bumps on their corneas, and the the array of bumps creates a situation in which almost no reflection exists, thus keeping the defenseless moth hidden from nocturnal predators; researchers want to increase the efficiency of solar panels by emulating moth eyes, allowing the panels to absorb and utilize — rather than reflect and waste — more of the sun’s light

Researching new laser and sensor technology
New materials would allow laser light to be generated in ranges that are not currently accessible; “These lasers could be used for sensing such as in detecting environmental conditions in a building,” says Binghamton University’s professor Oana Malis; “There are defense applications as well”

Maintaining security at Israel's Ben Gurion Airport
In 2006, Israel’s Ben Gurion Airport handled 9 million international passengers and 405,000 domestic passengers; it did so while being among the world’s most secure — if not the most secure — airports; two Israeli companies, Hi-Tech Solutions and Rontal, made their own contributions to achieving that level of security

Preventing future Deep Impact
The recent shooting down of a dysfunctional U.S. satellite, let alone the damage that a large asteroid would inflict if allowed to hit Earth, highlight the need to prevent natural or man-made space objects from doing damage on Earth; nine Israeli science students offer a solution

Solar energy conversion breakthrough
Scientists say that sunlight falling on only 9 percent of California’s Mojave Desert could power all of the U.S. electricity needs — if the energy could be efficiently harvested; this is a big “if,” since current-generation solar cell technologies are too expensive and inefficient for wide-scale commercial applications; Northwestern University researchers show a way to increase solar cell efficiency

TSA lab's new concept in airport security: Tunnel of Truth
Futuristic vision of airport security would see passengers stand on a conveyor belt moving under an archway as different sensors scan them for weapons, bombs, and other prohibited items; no need to take the shoes off; by the time they step out of the tunnel, they have been thoroughly checked out

Cleaner water through nanotechnology
As global warming causes more and more countries to have less and less fresh water for human consumption and irrigation, the purification and re-use of contaminated water becomes more urgent; Aussie researchers offer a nanotechnology-based method to purify water which is more effective and cheaper than conventional water purification methods

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.
