Detecting radioactive material remotely
Physicists have developed a powerful new method to detect radioactive material. By using an infrared laser beam to induce a phenomenon known as an electron avalanche breakdown near the material, the new technique is able to detect shielded material from a distance. The method improves upon current technologies that require close proximity to the radioactive material.

Historic, widespread flooding to continue through May
Nearly two-thirds of the Lower 48 states face an elevated risk for flooding through May, with the potential for major or moderate flooding in 25 states, according to NOAA’s U.S. Spring Outlook issued today. The majority of the country is favored to experience above-average precipitation this spring, increasing the flood risk.

Rapidly melting tall ice-cliffs may trigger faster sea-level rise
Glaciers that drain ice sheets such as Antarctica or Greenland often flow into the ocean, ending in near-vertical cliffs. As the glacier flows into the sea, chunks of the ice break off in calving events. Although much calving occurs when the ocean melts the front of the ice, and ice cliff above falls down, a new study presents another method of calving: slumping. And this process could break off much larger chunks of ice at a quicker rate.

Offshore wind energy potential not exploited by U.S. energy companies
When it comes to wind energy, the United States is sitting on a gold mine, so to speak. It’s a moment of untapped potential that, if harnessed properly, could transform the way the U.S. uses energy, one expert says.

Satellite technology detects, and may prevent, genocide
Many of the world’s worst human rights abuses, including genocides, occur in areas that are difficult to observe. “Smallsat” — short for small satellite — technology can detect human rights abuses and violations. The information collected by this technology provides evidence that can be used to corroborate refugee accounts of atrocities in international courts.

Potential impacts of future heat waves on humans and wildlife
Climate change is often talked about in terms of averages — like the goal set by the Paris Agreement to limit the Earth’s temperature increase to 2 degrees Celsius. What such numbers fail to convey is that climate change will not only increase the world’s average temperature, it will also intensify extreme heat waves that even now are harming people and wildlife.

Smart sensor to enhance emergency communications
First responders run toward danger; their jobs require it. Often, their only connection to the outside world during these rescue missions is their colleagues at the command centers who coordinate the rescue effort. with the ubiquity of IoT devices now, first responders have access to a vast, timely, and smart network of connections to the outside world.

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
By Trina West
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.
