Harrison Ford Reveals His Preferred Version of ‘Blade Runner’

gizmodo.com Germain Lussier 2025-12-24 06:20:31

One of the nerdiest conversations two sci-fi fans can have is about the merits of the different versions of Blade Runner. Which is best? What does one decision mean? How about another? And one person you’d never expect to weigh in on that is Harrison Ford himself. Ford is, of course, the star of Blade Runner along with one or two other major sci-fi films. Even so, he’s not really a sci-fi nerd by any stretch of the imagination. However, in a new interview, he did offer a very specific answer to

Starlink Is Set to Receive Billions in Federal Subsidies but Analysis Says It Can’t Handle the Traffic

Key takeaways A new X-Lab analysis indicates Starlink can only support 6.66 households per square mile before speeds drop below FCC broadband minimums (100/20 Mbps). Currently, only 17% of Starlink users currently meet FCC broadband speeds, yet altered BEAD program rules could direct significant federal funds to Starlink as the lowest-cost option. While Starlink greatly improves internet access and quality for rural Americans, experts worry about its long-term viability for widespread broadban

How a New Jersey startup found an electrifying way to slash copper costs

techcrunch.com Tim De Chant 2025-12-24 06:09:47

Skyrocketing demand for copper promises to push prices to new heights. As the global economy transitions away from fossil fuels, it is going to need twice as much copper in the coming years than humanity has mined throughout all of its existence. Still Bright, a New Jersey-based startup founded in 2022, thinks it has found a novel (and cleaner way) to slash those costs. “The fact that we’ve already mined the easily mineable stuff, and the fact that we need many more mines to come into producti

The AI Hype Index: The White House’s war on “woke AI”

technologyreview.com The Editors 2025-12-24 11:37:10

Separating AI reality from hyped-up fiction isn’t always easy. That’s why we’ve created the AI Hype Index—a simple, at-a-glance summary of everything you need to know about the state of the industry. The Trump administration recently declared war on so-called “woke AI,” issuing an executive order aimed at preventing companies whose models exhibit a liberal bias from landing federal contracts. Simultaneously, the Pentagon inked a deal with Elon Musk’s xAI just days after its chatbot, Grok, spout

Linux PC acting up? How to check for bad blocks on a hard drive - before it's too late

YouTube loosens profanity rules for monetized videos

techcrunch.com Ivan Mehta 2025-12-24 16:01:21

YouTube is tweaking its profanity-related rules to allow creators to monetize videos with swearing in them, provided the profanity is contained to the first seven seconds of the video. In November 2022, YouTube changed its rules so that creators who used swear words in the first 8-15 seconds would potentially be ineligible for any ad revenue. After much backlash, the company changed its rules again in March 2023 so that such videos would be eligible for limited ad revenue, unless they use profa

Psychedelic Therapy Crashed and Burned. MAHA Might Bring It Back

This was supposed to be the year of the MDMA revolution. About this time last year, prescription MDMA looked like a sure thing. After decades of clinical research, political wrangling, and aggressive promotion, the popular underground club drug was set to be tamed and medicalized, with a stamp of approval from the US Food and Drug Administration. Then, it wasn’t. In a stark change of course, the FDA rejected the MDMA therapy it had been considering by a 10-1 vote. The decision derailed psyched
