Exosomes are touted as a trendy cure-all. We don’t know if they work.
There’s a trendy new cure-all in town—you might have seen ads pop up on social media or read rave reviews in beauty magazines.
Exosomes are being touted as a miraculous treatment for hair loss, aging skin, acne, eczema, pain conditions, long covid, and even neurological diseases like Parkinson’s and Alzheimer’s. That’s, of course, if you can afford the price tag—which can stretch to thousands of dollars.
But there’s a big problem with these big promises: We don’t fully understand how exosomes work—or what they even really are. Read our story.

AI will add to the e-waste problem. Here’s what we can do about it.
The news: Generative AI could add up to 5 million metric tons of e-waste in total by 2030, according to a new study. That’s a relatively small fraction of the current global total of over 60 million metric tons of e-waste each year. However, it’s still a significant part of a growing problem.
Under the hood: The primary contributor is high-performance computing hardware that’s used in data centers and server farms. That equipment is full of valuable metals and hazardous materials, and it’s being replaced at a rapid rate as AI companies race to adopt the most cutting-edge hardware to power their models.
What can be done: Expanding hardware’s lifespan is one of the most significant ways to cut down on e-waste. Refurbishing and reusing components can also play a significant role, as can designing hardware in ways that makes it easier to recycle and upgrade. Read the full story.

Militaries are great testing grounds for AI tech, says Palmer Luckey
War is a catalyst for technological change, and the last couple of years have been marred by high-profile conflicts around the world. Geopolitical tensions are still rising now.
Silicon Valley players are poised to benefit. One of them is Palmer Luckey, the founder of the virtual-reality headset company Oculus, which he sold to Facebook for $2 billion. After Luckey’s highly public ousting from Meta, he founded Anduril, which focuses on drones, cruise missiles, and other AI-enhanced technologies for the US Department of Defense. The company is now valued at $14 billion. We interviewed Luckey about his new project: headsets for the military.
But the use of AI for the military is a controversial topic, with a long and bitter history that stretches from Project Maven to killer robots. Read the full story.

Meet the radio-obsessed civilian shaping Ukraine’s drone defense
September 2024
Drones have come to define the brutal conflict in Ukraine that has now dragged on for more than two and a half years. And most rely on radio communications—a technology that Serhii “Flash” Beskrestnov has obsessed over since childhood.
While Flash is now a civilian, the former officer has still taken it upon himself to inform his country’s defense in all matters related to radio. He studies Russian transmissions and tries to learn about the problems facing troops.
In this race for survival—as each side constantly tries to best the other, only to start all over again when the other inevitably catches up—Ukrainian soldiers need to develop creative solutions, and fast. As Ukraine’s wartime radio guru, Flash may just be one of their best hopes for doing that. Read the full story.
