Local LLMs versus offline Wikipedia

news.ycombinator.com Evan Hahn 2025-07-19 21:49:02

Two days ago, MIT Technology review published “How to run an LLM on your laptop”. It opens with an anecdote about using offline LLMs in an apocalypse scenario. “‘It’s like having a weird, condensed, faulty version of Wikipedia, so I can help reboot society with the help of my little USB stick,’ [Simon Willison] says.” This made me wonder: how do the sizes of local LLMs compare to the size of offline Wikipedia downloads? I compared some models from the Ollama library to various downloads on Kiw

There could be “dark main sequence” stars at the galactic center

arstechnica.com Unknown 2025-07-27 02:30:58

For a star, its initial mass is everything. It determines how quickly it burns through its hydrogen and how it will evolve once it starts fusing heavier elements. It's so well understood that scientists have devised a "main sequence" that acts a bit like a periodic table for stars, correlating their mass and age with their properties. The main sequence, however, is based on an assumption that's almost always true: All of the energy involved comes from the gravity-driven fusion of lighter elemen

Google’s Discover feed may be getting an AI feature no one asked for

androidauthority.com Unknown 2025-07-29 08:49:42

Joe Maring / Android Authority TL;DR Google is testing AI summaries for articles in the Discover feed. Like AI overviews in Google Search, Discover feed summaries combine information from multiple sources instead of just referencing one. Google is also testing a new button to bookmark articles that can be revisited later. Of late, Google has been experimenting with multiple ways to make its AI applications more visible, especially to users who have steered clear of Gemini so far. After rolli

Scientists Discover Secret Weapon That Allows Pythons to Digest Bones

gizmodo.com Ellyn Lapointe 2025-08-07 11:00:40

Pythons are notorious for their eating habits. After suffocating their prey with their lithe bodies, these large snakes swallow the animal whole. Now, researchers have shed new light on the cellular mechanisms that allow them to digest entire skeletons. The study, presented July 9 at the Society for Experimental Biology Annual Conference in Belgium and published in the Journal of Experimental Biology, investigated the intestinal cells of Burmese pythons. Adult males can grow to be 10 to 16 feet

Cancer-targeting nanoparticles are moving closer to human trials

technologyreview.com Anne Trafton 2025-08-30 13:00:00

In the original production technique, layers with different properties can be laid down by alternately exposing a particle to positively and negatively charged polymers, with extensive purification to remove excess polymer after each application. Each layer can carry therapeutics as well as molecules that help the particles find and enter cancer cells. But the process is time-consuming and would be difficult to scale up. In the new work, the researchers used a microfluidic mixing device that al

You'll Be Flabbergasted to Learn Which Contains More Microplastics: Plastic Bottles or Glass Bottles

You'll Be Flabbergasted to Learn Which Contains More Microplastics: Plastic Bottles or Glass Bottles "We expected the opposite result." Bottom of the Bottle French government scientists have discovered something startling about the microplastic content in glass and plastic bottles. As the Agence France-Presse reports, scientists at the country's food safety regulator found that glass-bottled drinks contained about 100 microplastic particles per liter, which amounts to roughly 25 particles pe

Drinks in glass bottles contain more microplastics than those in other container

news.ycombinator.com Unknown 2025-09-03 13:01:34

The aim of the ANSES study was to determine the level of microplastic contamination in drinks such as water, soda, iced tea, wine and beer; it also sought to establish the impact of their containers on this level. For most of the drinks studied, the level of microplastics was found to be higher in glass bottles than in other containers. For example, on average, in glass bottles of cola, lemonade, iced tea and beer, there were around 100 microplastic particles per litre. This number was five to 5

I tried replacing Google Search with Perplexity. It didn’t go well

Joe Maring / Android Authority It’s no secret that Google Search is in a weird place right now. The regular search experience has seen better days, with ads and unhelpful results making the search engine feel far less helpful than it was a few years ago. Meanwhile, artificial intelligence features like AI Overviews and AI Mode aren’t where they need to be. Despite its imperfections, Google Search has remained my go-to search engine. But why should it when there are so many other options out th

Scented products cause indoor air pollution on par with car exhaust

news.ycombinator.com Patra Et Al. 2025-06-04 02:53:28

Using scented products indoors changes the chemistry of the air, producing as much air pollution as car exhaust does outside, according to a new study. Researchers say that breathing in these nanosized particles could have serious health implications. When you hear or see the words ‘air pollution,’ you most likely think of things like factories and car exhaust. That’s pollution that is out there – outside your house. But have you thought about how you’re contributing to air pollution inside of
