In Coastal Communities, Sea Level Rise May Leave Some Isolated
Amid the threat of dramatic sea level rise, coastal communities face unprecedented dangers, but a new study reveals that as flooding intensifies, disadvantaged populations will be the ones to experience some of the most severe burdens of climate change.

Evolution Might Stop Humans from Solving Climate Change
Central features of human evolution may stop our species from resolving global environmental problems like climate change, says a new study. Can humans continue to survive on a limited planet? “We don’t have any solutions for this idea of a long-term evolutionary trap, as we barely understand the problem,” says one expert.

The Link Between Climate Change and a Spate of Rare Disease Outbreaks in 2023
The temperature-sensitive pathogens that caught U.S. communities off guard are a grim preview of the future. Scientists have warned that climate change would alter the prevalence and spread of disease in the U.S., particularly those caused by pathogens that are sensitive to temperature.

Does AI Enable and Enhance Biorisks?
The diversity of the biorisk landscape highlights the need to clearly identify which scenarios and actors are of concern. It is important to consider AI-enhanced risk within the current biorisk landscape, in which both experts and non-experts can cause biological harm without the need for AI tools, thus highlighting the need for layered safeguards throughout the biorisk chain.

Generative AI and Weapons of Mass Destruction: Will AI Lead to Proliferation?
Large Language Models (LLMs) caught popular attention in 2023 through their ability to generate text based on prompts entered by the user. Ian J. Stewart writes that “some have raised concerns about the ability of LLMs to contribute to nuclear, chemical and biological weapons proliferation (CBRN). Put simply, could a person learn enough through an interaction with an LLM to produce a weapon? And if so, would this differ from what the individual could learn by scouring the internet?”

Evaluating the Truthfulness of Fake News Through Online Searches Increases the Chances of Believing Misinformation
Conventional wisdom suggests that searching online to evaluate the veracity of misinformation would reduce belief in it. But a new study by a team of researchers shows the opposite occurs: Searching to evaluate the truthfulness of false news articles actually increases the probability of believing misinformation.

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.

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.
Falling Space Debris: How High Is the Risk I'll Get Hit?

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.
Testing Cutting-Edge Counter-Drone Technology
Drones have many positive applications, bad actors can use them for nefarious purposes. Two recent field demonstrations brought government, academia, and industry together to evaluate innovative counter-unmanned aircraft systems.
