Previously Unknown Pathway to Batteries with High Energy, Low cost and Long Life
The road from breakthrough in the lab to practical technology can be a long and bumpy one. The lithium-sulfur battery is an example. It has notable advantages over current lithium-ion batteries powering vehicles. But it has yet to dent the market despite intense development over many years. That situation could change in the future, as scientists discover surprising pathway to better lithium-sulfur batteries by visualizing reactions at the atomic scale.

How the Drone War in Ukraine Is Transforming Conflict
From drones that fit in the palm of the hand to drones weighing more than 1,000 pounds (454 kilograms), Ukraine has built and acquired a diverse fleet of remotely piloted aircraft to complicate and frustrate Russia’s advances. The constantly evolving scope of this technology and its ever-growing use signal not only the potential for drones to level the playing field in the Russia-Ukraine war, but also their ability to influence how future conflicts are waged.

Iceland Battles a Lava Flow: Countries Have Built Barriers and Tried Explosives in the Past, but It’s Hard to Stop Molten Rock
Fountains of lava erupted from the Sundhnúkur volcanic system in southwest Iceland on Jan. 14, 2024, invading the outskirts of the coastal town of Grindavík. Humans have tried many ways to stop lava in the past, from attempting to freeze it in place by cooling it with sea water, to using explosives to disrupt its supply, to building earthen barriers. It’s too soon to say if Iceland’s earthworks will succeed in saving Grindavík, a town of about 3,500 residents, and a nearby geothermal power plant.

Don’t Bring a Patriot to a Drone Fight—Bring Fighter UAVS Instead
Recent conflicts such as the war in Ukraine and the 2020 war in Nagorno-Karabakh demonstrate the growing importance of unmanned aerial vehicles. Naturally, there have been attempts to defeat this new threat. No matter the defense mechanism chosen, there just are not enough systems to provide sufficient protection against swarms of UAVs. The solution for this dilemma is to take the next step in UAV evolution: air superiority drones.

“Killer Robots” Are Coming, and UN Is Worried
Long the stuff of science fiction, autonomous weapons systems, known as “killer robots,” are poised to become a reality, thanks to the rapid development of artificial intelligence. In response, international organizations have been intensifying calls for limits or even outright bans on their use. Human rights specialist lays out legal, ethical problems of military weapons systems that attack without human guidance.

California’s Salton Sea Region a Rich Domestic Lithium Resource
The United States currently has limited capabilities to recover, refine, and produce domestically sourced lithium, meaning nearly all lithium for U.S. needs must be imported. The most comprehensive analysis to date quantifying the domestic lithium resources in southern California’s Salton Sea region found that the total resources in the region could contain more than 3,400 kilotons of lithium, enough to support over 375 million batteries for electric vehicles (EV).

Identifying Types of Cyberattacks That Manipulate Behavior of AI Systems
AI systems can malfunction when exposed to untrustworthy data – what is called “adversarial machine learning” — and attackers are exploiting this issue. New guidance documents the types of these attacks, along with mitigation approaches. No foolproof method exists as yet for protecting AI from misdirection, and AI developers and users should be wary of any who claim otherwise.

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.

The Tech Apocalypse Panic is Driven by AI Boosters, Military Tacticians, and Movies
From popular films like a War Games or The Terminator to a U.S. State Department-commissioned report on the security risk of weaponized AI, there has been a tremendous amount of hand wringing and nervousness about how so-called artificial intelligence might end up destroying the world. There is one easy way to avoid a lot of this and prevent a self-inflicted doomsday: don’t give computers the capability to launch devastating weapons.
