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.

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.

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.

Encryption Breakthrough Lays Groundwork for Privacy-Preserving AI Models
In an era where data privacy concerns loom large, a new approach in artificial intelligence (AI) could reshape how sensitive information is processed. New AI framework enables secure neural network computation without sacrificing accuracy.
AI-Controlled Fighter Jets May Be Closer Than We Think — and Would Change the Face of Warfare
Could we be on the verge of an era where fighter jets take flight without pilots – and are controlled by artificial intelligence (AI)? US R Adm Michael Donnelly recently said that an upcoming combat jet could be the navy’s last one with a pilot in the cockpit.
The Potential Impact of Seabed Mining on Critical Mineral Supply Chains and Global Geopolitics
The potential emergence of a seabed mining industry has important ramifications for the diversification of critical mineral supply chains, revenues for developing nations with substantial terrestrial mining sectors, and global geopolitics.
AI and the Future of the U.S. Electric Grid
Despite its age, the U.S. electric grid remains one of the great workhorses of modern life. Whether it can maintain that performance over the next few years may determine how well the U.S. competes in an AI-driven world.
