    By Zulfikar Abbany, Julia Vergin, and Katja Sterzik

    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.

  • 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.

    By Christoph Schmon

    In a milestone judgment—Podchasov v. Russia—the European Court of Human Rights (ECtHR) has ruled that weakening of encryption can lead to general and indiscriminate surveillance of the communications of all users and violates the human right to privacy.

  • CRITICAL MINERALSChina Shows How Western Governments Should Stockpile Minerals

    By Gregory D. Wischer

    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

    By Naveena Sadasivam

    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.

    By Emily Foxhall

    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.

  • ENERGY WEAPONSHigh-Energy Laser Weapons: How They Work and What They Are Used For

    By Iain Boyd

    Laser weapons have been a staple of science fiction since long before lasers were even invented. More recently, they have also featured prominently in some conspiracy theories. Both types of fiction highlight the need to understand how laser weapons actually work and what they are used for.

  • POWER-GRID SECURITYScientists Put Forth a Smarter Way to Protect a Smarter Grid

    By Tom Rickey

    Proliferation of programmable devices presents more gateways for cyberattack. That makes the electric grid, increasingly chock full of devices that interact with one another and make critical decisions, vulnerable to bad actors who might try to turn off the power, damage the system or worse.

  • AI CHIPDemand for Computer Chips Fueled by AI Could Reshape Global Politics and Security

    By Kirk Chang and Alina Vaduva

    A global race to build powerful computer chips that are essential for the next generation of artificial intelligence (AI) tools could have a major impact on global politics and security. The US is currently leading the race in the design of these chips, also known as semiconductors. But most of the manufacturing is carried out in Taiwan.
