AIRPORT SECURITYPrototype 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.

AUTONOMOUS VEHICLESAutonomous 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.

CRITICAL MINERALSChina Shows How Western Governments Should Stockpile Minerals
The US, Australia and partner countries should take a page from China’s stockpiling playbook. They should build up stockpiles of critical minerals, managing inventories to optimize prices for domestic mineral producers and consumers and to guard against decreased supply and increased demand in wartime.

TEXAS WILDFIRESHow Climate Change Primed Texas to Burn
Over the past 10 days, five wildfires in the region have burned more than 1.2 million acres. The largest of them — dubbed the Smokehouse Creek Fire, for a creek near its origin — stretches across an area larger than Rhode Island. The state’s high plains get a month more fire weather now than they did in the 1970s.

TEXAS WILDFIRESTexas Requires Utilities to Plan for Emergencies. That Didn’t Stop the Panhandle Fires.
Experts say utilities need to be ready for extreme weather, which could be a challenge in a state where discussing climate change is often taboo. A review of portions of the state’s electricity code shows utilities have to plan for maintaining their equipment and responding in emergencies, but how they do so is largely left to the companies.

CRITICAL MATERIALSRevolutionizing Resource Renewal: Scaling Up Sustainable Recycling for Critical Materials
Permanent magnets, which retain magnetic properties even in the absence of an inducing field or current, are used extensively in clean energy and defense applications. Rare earths are challenging to access because they are scattered across Earth’s crust, yet they are key components in many modern technologies. Recycled rare earths can be used to make new permanent magnets, accelerate chemical reactions and improve the properties of metals when included as alloy components.
EMERGENCY RESPONSESaving Seconds, Saving Lives: NIST-Funded Challenge Crowns Winners in 3D Tracking Technology
NIST has awarded $1.9 million to six teams for innovative 3D tracking solutions in the final phase of a competition. The winning designs combine localization and biometric monitoring, using sensors affixed to first responders’ equipment. This competition is part of an $8 million NIST-funded initiative to address first responders’ need for improved tracking in emergency settings where GPS falls short.
DISASTERSNumber of People Affected by Tropical Cyclones Has Increased Sharply Since 2002
The number of people affected by tropical cyclones has nearly doubled from 2002 to 2019, reaching nearly 800 million people in 2019, according to a new study. More people are affected by tropical cyclones in Asia than any other region, but every affected world region saw an increase in the number of people exposed to tropical cyclones, which are expected to become more intense and possibly more frequent as the climate warms.
