The Future of Nuclear Waste: What’s the Plan and Can It Be Safe?
The UK is planning to significantly expand its nuclear capability — from approximately 8 gigawatts (GW) today to 24GW by 2050, which would meet around 25% of the forecast UK energy demand — in an effort to decrease its reliance on carbon-based fossil fuels. New reactors will inevitably mean more radioactive waste. Above-ground nuclear waste storage isn’t a feasible long term plan. What are the alternatives?

Boosting Efforts to Predict Harmful Solar Weather Events
When big blasts of energy from the sun envelop the Earth, they can very strong: a 2015 event so weakened Earth’s protective magnetic field that it penetrated to the atmosphere, posing a threat to everything from circling space station astronauts to delicate electronics and communication systems.

The Movement to Ban Government Use of Face Recognition
Our faces are unique identifiers that can’t be left at home, or replaced like a stolen ID or compromised password. Facial recognition technology facilitates covert mass surveillance of the places we frequent, people we associate with, and, purportedly, our emotional state. Communities across the country are fighting back.

How Our Bushfire-Proof House Design Could Help People Flee Rather Than Risk Fighting the Flames
Building houses better at withstanding the impacts of climate change is one way we can protect ourselves in the face of future catastrophic conditions. I’m part of a research team that developed a novel, bushfire-resistant house design, which won an international award last month.

Ensuring Human Control over AI-Infused Systems
Human control over technology was a concern thousands of years ago when early humans sought to ensure safe use of fire. Later, control over horse-drawn wagons and eventually steam engines led to debates about how to make the most of their benefits while limiting dangers. Now questions of control are central in the design of AI-infused technologies, for which some advocates envision full machine autonomy while others promote human autonomy.

Americans Move to More Solar and Wind Power in 2021
In 2021, Americans used 5 percent more energy than in 2020. Solar and wind energy production increased drastically this past year, with jumps of 20 percent and 11 percent, respectively; biomass-derived energy also increased by 7 percent. These increases contrasted with hydro, geothermal and nuclear power, which decreased by 12 percent, 4 percent and 1 percent, respectively.

Artificial Intelligence and Chemical and Biological Weapons
A recent article in Nature offers a disturbing look at the use of artificial intelligence (AI) in the creation of chemical and biological weapons. “Anyone unfamiliar with recent innovations in the use of AI to model new drugs will be unpleasantly surprised,” Paul Rosenzweig writes. “The benefits of these innovations are clear. Unfortunately, the possibilities for malicious uses are also becoming clear.”

New Tool in the Fight Against Hackers
A new form of security identification could soon see the light of day and help us protect our data from hackers and cybercriminals. Quantum mathematicians have solved a mathematical riddle that allows for a person’s geographical location to be used as a personal ID that is secure against even the most advanced cyberattacks.

Risk Models Overlook an Important Element
Earthquakes themselves affect the movement of Earth’s tectonic plates, which in turn could impact on future earthquakes, according to new research. This new knowledge should be incorporated in computer models used to gauge earthquake risk, according to the researchers behind the study.

Aces-High Frontier: Space War in 2053
There are good reasons why the best science and speculative fiction ranks high on the reading lists of many military scholars and leaders. Done well, speculative military fiction projects thoughtfully beyond the here and now, and renders real operational and strategic concepts in terms of plausible future technologies.
What Is Microstamping, and Can It Help Solve Shootings?
Laws to expand the technology’s use have passed in three states and the District of Columbia. But some are questioning its effectiveness.
Creating Buildings That Can Withstand the Most Extreme Stress Loads
Combined ballistic impacts pose a major challenge for engineers who build structures that must withstand extreme stresses. An explosion can hurtle fragments and debris at enormous velocities so they strike the surroundings. Then comes the shock wave. It’s a scary combination.

Illuminating the Barrier to Next-Generation Battery That Charges Very Quickly
In the race for fast-charging, energy-dense lithium metal batteries, researchers discovered why the promising solid electrolyte version has not performed as hoped. This could help new designs – and eventually battery production – avoid the problem.
Great Leap Nowhere: The Challenges of China’s Semiconductor Industry
China is struggling in the battle for advanced semiconductor technology. With President Joe Biden’s most recent round of export controls on semiconductors, China is now facing an increasingly urgent challenge as it seeks to ramp up its domestic innovative capacity for high-end chips. These difficulties and challenges notwithstanding, Elliot Ji writes, “U.S. policymakers should be keenly aware that China’s relative success with creative adaptation means that it can boost certain sectors of the chip industry by exploiting leaky export controls and engaging in cyber espionage.”
AI Nuclear Weapons Catastrophe Can Be Avoided
There is a growing concern that emerging AI features will only increase the potential for disaster through the possibility of semiautonomous or fully autonomous nuclear weapons. Noah Greene writes that “As the Soviet-era Col. Petrov case kindly taught us, without a human firmly in control of the nuclear command-and-control structure, the odds of disaster creep slowly toward an unintended or uncontrolled nuclear exchange.”
