What Are the Odds of a Truly Catastrophic, Even Extinction-Causing, Disaster?
The Forecastong Research Institute (FRI) brought together forecasters from two groups with distinctive claims to knowledge about humanity’s future — experts in various domains relevant to existential risk, and “superforecasters” with a track record of predictive accuracy over short time horizons. FRI asked tournament participants to predict the likelihood of global risks related to nuclear weapon use, biorisks, and AI, along with dozens of other related, shorter-run forecasts.

A Quantitative Analysis of the In-Orbit Collision Risk and Its Effects on the Earth
Since the launch of the first satellite in 1957, the proliferation of space debris has continued unabated. The European Space Agency (ESA) estimates that over 131 million useless objects, ranging from 1 millimeter to 10 centimeters in size, currently orbit the Earth at an average speed of 36,000 kilometers per hour. “Any fragment larger than 1 centimeter poses a potentially lethal threat in the event of a collision,” says an expert.

Sooner Than You Might Think: Virtual Power Plants Are Coming to Save the Grid
Networks of thousands of home-based batteries could be key to a cleaner, more reliable electricity system. After years of pilot projects, utilities and battery companies now have networks with thousands of participants in California, Utah, and Vermont, among others.

Researchers Devise a Way to Evaluate Cybersecurity Methods
A savvy hacker can obtain secret information, such as a password, by observing a computer program’s behavior, like how much time that program spends accessing the computer’s memory. Security approaches that completely block these “side-channel attacks” are so computationally expensive, so engineers often apply what are known as obfuscation schemes. MIT researchers have developed a system which analyzes the likelihood that an attacker could thwart a certain security scheme to steal secret information.

U.S. Agencies Buy Vast Quantities of Personal Information on the Open Market – a Legal Scholar Explains Why and What It Means for Privacy in the Age of AI
The issues pf the protection of personal information in the digital age is increasingly urgent. Today’s commercially available information, coupled with the now-ubiquitous decision-making artificial intelligence and generative AI like ChatGPT, significantly increases the threat to privacy and civil liberties by giving the government access to sensitive personal information beyond even what it could collect through court-authorized surveillance.

Four Ways Criminals Could Use AI to Target More Victims
Warnings about artificial intelligence (AI) are ubiquitous right now, but we have been using AI tools for a long time. AI is a tool to increase efficiency, process and sort large volumes of data, and offload decision making – and these tools are open to everyone, including criminals. Observing how criminals have adapted to, and adopted, technological advances in the past, can provide some clues as to how they might use AI.

Robots Could Help Verify Compliance with Nuclear Arms Agreements
Ensuring that countries abide by future nuclear arms agreements will be a vital task. Inspectors may have to count warheads or confirm the removal of nuclear weapons from geographical areas. Those hotspots could include underground bunkers and require confirmation that no weapons exist in a location at all. Now, researchers have devised an automated way to ensure compliance.

AI-Controlled Weapons Should Be Banned from the Battlefield: Experts
AI expert says autonomous systems being used in the current Ukraine conflict need to be prohibited in the same way as chemical and biological weapons. “I’m quite hopeful that we will, at some point, decide that autonomous weapons also be added to the lists of terrible ways to fight war like chemical weapons, like biological weapons. What worries me is that in most cases, we’ve only regulated various technologies for fighting after we’ve seen the horrors of them being misused in battle,” he says.
Using Quantum Computing to Protect AI from Attack
Despite their incredible successes and increasingly widespread deployment, machine learning-based frameworks such as AI remain highly susceptible to adversarial attacks – that is, malicious tampering with their data causing them to fail in surprising ways. AI can thus be fooled into making mistakes, sometimes risking lives — but quantum computing could provide a strong defense.
Training Students to Succeed in the “Fourth Industrial Revolution”
Transformational changes are already underway in the manufacturing industry as technological advancements, such as artificial intelligence (AI) and smart devices from the “fourth industrial revolution” or Industry 4.0., inspire a digital-first approach to engineering. University of Missouri researchers are using a $1 million grant to support the development of an Industry 4.0 lab, training engineering students for the future of digitization in manufacturing.
Tech Breakthrough Could Increase States’ Use of Geothermal Power
Lawmakers in some states have been laying the groundwork to add geothermal power to the electrical grid and pump underground heat into buildings. Now, a technological breakthrough could dramatically expand those ambitions — and perhaps unleash a new wave of policies to tap into geothermal sources. If the technology’s promise is fulfilled, geothermal could power as much as 20% of the U.S. grid.
Using Hydrogen to Power Disaster Relief
A new vehicle will not only get emergency responders safely to the site of an emergency, but also directly provide power at the scene for up to 72 hours as they assess next steps. And it does all this running on hydrogen—a much more sustainable solution for our environment.
Wastewater Can Help Tackle Water Shortages
Europe has experienced severe heat and drought over the last few summers, and 2023 has been no different. Vast swathes of Central and Southern Europe are simply too dry from a lack of rainfall. Water shortages are causing tensions in some countries. But, for now, there’s enough water to go around. Using the precious resource more efficiently is key.
Sediment Movement During Hurricane Harvey Could Negatively Impact Future Flooding
Enormous amounts of sediment, or sand and mud, flowed through Houston waterways during Hurricane Harvey in 2017, due in part to modifications made by humans to bayous, rivers and streams over the past century. Harvey was the largest rainfall event in U.S. history, and it moved 27 million cubic meters of sediment, or 16 Astrodomes, through Houston waterways and reservoirs. This could seriously impact future flooding events and be costly to the City of Houston.
A Review of NIST’s Draft Cybersecurity Framework 2.0
Cybersecurity professionals, and anyone interested in cybersecurity, have noted that the gold standard of cybersecurity is getting a needed polish. “But all that glitters is not gold,” Melanie Teplinsky writes. NIST’s voluntary cybersecurity framework leaves organizations vulnerable to the nation’s most capable cyber adversaries. NIST’s proposed overhaul won’t change that.
