RIP to Horror Icon Scott Spiegel, Co-Writer of ‘Evil Dead II’

You might not immediately recognize the name Scott Spiegel, but if you—like most horror fans—are a sworn devotee of the legendary splatter comedy Evil Dead II, you are well familiar with his work. Spiegel, who passed away this week at age 67, co-wrote that film with a buddy of his since high school: director Sam Raimi. He had also acted in Within the Woods, Raimi’s proof-of-concept that later helped him make the first Evil Dead. Spiegel’s other credits include co-writing the Clint Eastwood thri

TED leader’s $300M ‘valley of death’ fund might be just what later-stage climate tech needs

Like many startups, climate tech companies often face a “valley of death” that lies between early stage funding and growth capital that helps proven technologies reach commercial scale. But because climate tech startups are often hardware focused — physical problems tend to require physical solutions, after all — this valley of death tends to be a lot wider. Financing a first-of-a-kind power plant or factory can cost tens or hundreds of millions of dollars. Now, a new fund hopes to bridge this

This Electric Shaver Is Made From Aircraft-Grade Aluminium, Because Why Not?

Nothing says “premium” like aerospace-grade aluminum alloy, am I right? I guess. I don’t know, it sounds fancy and it looks fancy, too, which makes Laifen’s new electric shaver, the T1 Pro, the swankiest electric shaver I’ve seen all day. The T1 Pro, which was announced at IFA 2025, is apparently crafted with “a single block of aerospace-grade aluminum alloy,” which makes this over-engineered shaver both light and very durable, according to Laifen.

Going to Space Could Make Your Cells Age Faster

Spaceflight pushes the human body to its limits, exposing astronauts to microgravity, high levels of radiation, and extended periods of isolation. These stressors affect their health in various ways, many of which scientists are still working to fully understand. But if we are ever to boldly go where no human has gone before, we need to know all the risks before we take the leap. And now new research published Thursday, September 4 in the journal Cell Stem Cell offers clues to another facet of

Electromechanical reshaping offers safer eye surgery

A high schooler writes about AI tools in the classroom

AI has transformed my experience of education. I am a senior at a public high school in New York, and these tools are everywhere. I do not want to use them in the way I see other kids my age using them—I generally choose not to—but they are inescapable. During a lesson on the Narrative of the Life of Frederick Douglass, I watched a classmate discreetly shift in their seat, prop their laptop up on a crossed leg, and highlight the entirety of the chapter under discussion. In seconds, they had pul
