New Nuclear Deflection Simulations Advance Planetary Defense Against Asteroid Threats
As part of an effort to test different technologies to protect Earth from asteroids, a kinetic impactor was deliberately crashed into an asteroid to alter its trajectory. However, with limitations in the mass that can be lifted to space, scientists continue to explore nuclear deflection as a viable alternative to kinetic impact missions. Nuclear devices have the highest ratio of energy density per unit of mass of any human technology, making them an invaluable tool in mitigating asteroid threats.

Planning for an Uncertain Future: What Climate-Related Conflict Could Mean for U.S. Central Command
The Middle East and Central Asia are projected to become hotter and drier, with reduced access to fresh water, resulting from climate change. These changes could lead to greater conflict in U.S. Central Command’s (CENTCOM) area of responsibility.

Artificial Intelligence Systems Excel at Imitation, but Not Innovation
Artificial intelligence (AI) systems are often depicted as sentient agents poised to overshadow the human mind. But AI lacks the crucial human ability of innovation. While children and adults alike can solve problems by finding novel uses for everyday objects, AI systems often lack the ability to view tools in a new way.

Why Federal Efforts to Protect Schools from Cybersecurity Threats Fall Short
In August 2023, the White House announced a plan to bolster cybersecurity in K-12 schools – and with good reason. Between 2018 and mid-September 2023, there were 386 recorded cyberattacks in the U.S. education sector and cost those schools $35.1 billion. K-12 schools were the primary target. While the steps taken by the White House are positive, as someone who teaches and conducts research about cybersecurity, I don’t believe the proposed measures are enough to protect schools from cyberthreats.

ChatGPT Could Help First Responders During Natural Disasters
A little over a year since its launch, ChatGPT’s abilities are well known. The machine learning model can write a decent college-level essay and hold a conversation in an almost human-like way. But could its language skills also help first responders find those in distress during a natural disaster?

AI Networks Are More Vulnerable to Malicious Attacks Than Previously Thought
Artificial intelligence tools hold promise for applications ranging from autonomous vehicles to the interpretation of medical images. However, a new study finds these AI tools are more vulnerable than previously thought to targeted attacks that effectively force AI systems to make bad decisions.

Smart Microgrids Can Restore Power More Efficiently and Reliably in an Outage
It’s a story that’s become all too familiar — high winds knock out a power line, and a community can go without power for hours to days, an inconvenience at best and a dangerous situation at worst. Engineers developed an AI model that optimizes the use of renewables and other energy sources to restore power when a main utility fails.

Seaworthy Solution Yields Green Energy, Fresh Water
Engineers have refined a model that not only cultivates green energy, but also desalinates ocean water for large, drought-stricken coastal populations.By pumping seawater to a mountaintop reservoir and then employing gravity to send the salty water down to a co-located hydropower plant and a reverse osmosis desalination facility, science can satisfy the energy and hydration needs of coastal cities with one system.

Researchers Fabricate Commercial Grade Uranium Dioxide HALEU Fuel
As the world clamors for carbon-free power, U.S. nuclear reactor developers have responded with several advanced reactor designs. Nuclear energy from light water reactors already ranks among the safest forms of energy production, and most advanced reactors will use safety systems that rely on the laws of physics to virtually eliminate the possibility of a serious accident.

National Opportunities to Remove Carbon Dioxide at the Gigaton Scale
Researchers have completed a first-of-its-kind high-resolution assessment of carbon dioxide (CO2) removal (CDR) in the United States. The report concludes that with today’s technologies, removing 1 billion metric tons of CO2 per year will annually cost roughly $130 billion in 2050, or about 0.5% of current GDP.

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.
