More than 60 companies now produce organs on chips commercially, focusing on five major organs: liver, kidney, lung, intestines, and brain. They’re already being used to understand diseases, discover and test new drugs, and explore personalized approaches to treatment. Could this be the end of animal testing?

Figuring out how the human body can withstand underwater pressure has been a problem for over a century, but a ragtag band of divers is experimenting with hydrogen to find out.

Palmer Luckey, the founder of Oculus VR, has set his sights on a new mixed-reality headset customer: the Pentagon.

His company Anduril Industries, which focuses on drones, cruise missiles, and other AI-enhanced technologies for the US Department of Defense, announced it would partner with Microsoft on the US Army’s Integrated Visual Augmentation System (IVAS), arguably the military’s largest effort to develop a headset for use on the battlefield.

Anduril’s contribution to the project will be Lattice, an AI-powered system that connects everything from drones to radar jammers to surveil, detect objects, and aid in decision-making. It’s a tool that allows soldiers to receive instantaneous information not only from Anduril’s hardware, but also from radars, vehicles, sensors, and other equipment not made by Anduril. Now it will be built into the IVAS goggles. Luckey says the IVAS project is his top priority at Anduril.

If designed well, the device will automatically sort through countless pieces of information—drone locations, vehicles, intelligence—and flag the most important ones to the wearer in real time.

But that’s a big “if.” Though few would bet against Luckey’s expertise in the realm of mixed reality, few observers share his optimism for the IVAS program. They view it, thus far, as an avalanche of failures.

Podcaster Joe Rogan, former presidential candidate Robert F. Kennedy, Jr., and football quarterback Aaron Rodgers are all helping revive AIDS denialism—a false collection of theories arguing either that HIV doesn’t cause AIDS or that there’s no such thing as HIV at all.  

These ideas were initially promoted back in the 1980s and ’90s by a cadre of scientists from unrelated fields, as well as many science-adjacent figures and self-proclaimed investigative journalists. But as more and more evidence stacked up against them, and as more people with HIV and AIDS started living longer lives thanks to effective new treatments, their claims largely fell out of favor. At least until the coronavirus arrived.

The newest versions of generative AI are bedazzling, with lifelike videos, seemingly expert-sounding prose, and other all too humanlike behaviors. Business leaders are fretting over how to reinvent their companies as billions flow into startups, and the big AI companies are creating ever more powerful models. Predictions abound on how ChatGPT and the growing list of large language models will transform the way we work and organize our lives, providing instant advice on everything from financial investments to where to spend your next vacation and how to get there.

But for economists, the most critical question around our obsession with AI is how the fledgling technology will (or won’t) boost overall productivity, and if it does, how long it will take. Think of it as the bottom line to the AI hype machine: Can the technology lead to renewed prosperity after years of stagnant economic growth?

It could. But getting there will take some serious course corrections.

Despite it being over 100 years old, radio technology is still critical in almost all aspects of modern warfare—including in the drones that have come to dominate the Russia-Ukraine war. But before the war, there was a frightening vacuum of expertise. Serhii “Flash” Beskrestnov, who has been obsessed with radios since childhood, stepped in to fill it. Now, the unlikely hero is sharing expert advice and intel on the ever-evolving technology that’s taken over the skies. His work may determine the future of Ukraine, and wars far beyond it.

You can practically hear the shrieks from corner offices around the world: “What is our ChatGPT play? How do we make money off this?”

Whether it’s based on hallucinatory beliefs or not, an AI gold rush has started to mine the anticipated business opportunities from generative AI models like ChatGPT.

But while companies and executives see a clear chance to cash in, the likely impact of the technology on workers and the economy on the whole is far less obvious.

Pump jacks and pipelines clutter the Elk Hills oil field of California, a scrubby stretch of land in the southern Central Valley that rests above one of the nation’s richest deposits of fossil fuels.

Oil production has been steadily declining in the state for decades, as tech jobs have boomed and legislators have enacted rigorous environmental and climate rules. Companies, towns, and residents across Kern County, where the poverty rate hovers around 18%, have grown increasingly desperate for new economic opportunities.

In late 2023, one of the state’s largest oil and gas producers secured draft permits from the US Environmental Protection Agency to develop a new type of well in the oil field, which it asserts would provide just that. If the company gets final approval from regulators, it intends to drill a series of boreholes down to a sprawling sedimentary formation roughly 6,000 feet below the surface, where it will inject tens of millions of metric tons of carbon dioxide to store it away forever.

Hundreds of similar projects are looming across the state, the US, and the world. Proponents hope it’s the start of a sort of oil boom in reverse, kick-starting a process through which the world will eventually bury more greenhouse gas than it adds to the atmosphere. But opponents insist these efforts will prolong the life of fossil-fuel plants, allow air and water pollution to continue, and create new health and environmental risks that could disproportionately harm disadvantaged communities surrounding the projects, including those near the Elk Hills oil field.
