Making the Electron Microscope

🚀 Explore this awesome post from Hacker News đź“– đź“‚ Category: 📌 Main takeaway: Biological structures exist across a vast range of scales. At one end are whole organisms, varying in size from bacteria only a few micrometers across to mammals measured in feet. These can be seen with the naked eye or with simple light microscopes, which have been in use since the mid-1600s. At the smaller end, however, are atoms, amino acids, and proteins, spanning angstroms to nanometers in size.Observing molecules at this smaller scale allows us to untangle the finer mechanisms of life: how individual neurons connect…

Smartphones manipulate our emotions and trigger our reflexes — no wonder we’re addicted

🔥 Read this awesome post from Hacker News đź“– đź“‚ Category: âś… Key idea: The frequency and length of daily phone use continues to rise, especially among young people. It’s a global concern, driving recent decisions to ban phones in schools in Canada, the United States and elsewhere. Ă€ lire aussi : School smartphone bans reflect growing concern over youth mental health and academic performance Social media, gaming, streaming and interacting with AI chatbots all contribute to this pull on our attention. But we need to look at the phones themselves to get the bigger picture. As I argue in…

Alzheimer’s disease is notorious for scrambling patients’ daily rhythms. Restless nights with little…

Welcome to » LaserTweezer – Optical Trap

đź’Ą Check out this awesome post from Hacker News đź“– đź“‚ Category: âś… Here’s what you’ll learn: LaserTweezer – Optical Trap Optical Tweezers are scientific instruments to manipulate objects of microscopic size. These can be small plastic beads or biological material like cells. The trapping is achieved by focusing a laser beam on the dielectric particles that are then attracted to the region of strongest electric field, which is the center of the beam. The fact that samples under a microscope can be manipulated gives new possibilities to explore. The force applied on the object depends linearly on its displacement…

These include supporting projects that are facing licensing challenges, collecting copyright assignments, and addressing GPL violations. In this session, though, there was really only one topic that the audience wanted to know about: the interaction between free-software licensing and large language models (LLMs). Anybody hoping to exit the session…

You should feed the bots: (Maurycy’s blog)

🚀 Discover this trending post from Hacker News đź“– đź“‚ Category: đź’ˇ Here’s what you’ll learn: Aug 3, 2025 (Programming) A week ago, I set up an infinite nonsense crawler trap – now it makes up 99% of my server’s traffic. What surprised me is that feeding scrapers garbage is the cheapest and easiest thing I could do. Meet the bots: These aren’t the indexing bots of old, but scrapers collecting data to train LLMs. Unlike search engines, which need the websites they crawl to stay up, AI companies provide a replacement. It should come as no surprise that these…
