Last April, an excited crowd gathered at a compound in Berkeley, California, for a three-day event called the Vitalist Bay Summit. It was part of a longer, two-month residency that hosted various events to explore tools—from drug regulation to cryonics—that might be deployed in the fight against death.

One of the main goals, though, was to spread the word of Vitalism, a somewhat radical movement established by Nathan Cheng and his colleague Adam Gries a few years ago. Consider it longevity for the most hardcore adherents—a sweeping mission to which nothing short of total devotion will do.

Although interest in longevity has certainly taken off in recent years, not everyone in the broader longevity space shares Vitalists’ commitment to actually making death obsolete. And the Vitalists feel that momentum is building, not just for the science of aging and the development of lifespan-extending therapies, but for the acceptance of their philosophy that defeating death should be humanity’s top concern.

The ability to remember you and your preferences is rapidly becoming a big selling point for AI chatbots and agents.

Personalized, interactive AI systems are built to act on our behalf, maintain context across conversations, and improve our ability to carry out all sorts of tasks, from booking travel to filing taxes.

But their ability to store and retrieve increasingly intimate details about their users over time introduces alarming, and all-too-familiar, privacy vulnerabilities––many of which have loomed since “big data” first teased the power of spotting and acting on user patterns. Worse, AI agents now appear poised to plow through whatever safeguards had been adopted to avoid those vulnerabilities. So what can developers do to fix this problem? Read the full story.

The eastern half of the US saw a monster snowstorm over the weekend. The good news is the grid has largely been able to keep up with the freezing temperatures and increased demand. But there were some signs of strain, particularly for fossil-fuel plants.

One analysis found that PJM, the nation’s largest grid operator, saw significant unplanned outages in plants that run on natural gas and coal. Historically, these facilities can struggle in extreme winter weather.

Much of the country continues to face record-low temperatures, and the possibility is looming for even more snow this weekend. What lessons can we take from this storm, and how might we shore up the grid to cope with extreme weather? Read the full story.

The flawed logic of rushing out extreme climate solutionsEarly in 2022, entrepreneur Luke Iseman says, he released a pair of sulfur dioxide–filled weather balloons from Mexico’s Baja California peninsula, in the hope that they’d burst miles above Earth.

It was a trivial act in itself, effectively a tiny, DIY act of solar geoengineering, the controversial proposal that the world could counteract climate change by releasing particles that reflect more sunlight back into space.

Entrepreneurs like Iseman invoke the stark dangers of climate change to explain why they do what they do—even if they don’t know how effective their interventions are. But experts say that urgency doesn’t create a social license to ignore the underlying dangers or leapfrog the scientific process. Read the full story.
