DOI:10.1128/msphere.00209-25 https://journals.asm.org/doi/10.1128/msphere.00209-25 Dust from California's drying Salton Sea doesn't just smell bad. Scientists from UC Riverside found that breathing the dust can quickly re-shape the microscopic world inside the lungs. Genetic or bacterial diseases have previously been shown to have an effect on lung microbes. However, this discovery marks the first time scientists have observed such changes from environmental exposure rather than a disease. Published in the journal mSphere, the study shows that inhalation of…

πŸ’₯ Discover this trending post from Hacker News πŸ“– πŸ“‚ Category: πŸ’‘ Here’s what you’ll learn: I've always worked better under pressure. High workload. Making things happen fast. Multiple projects I actually believe in. That's when I'm at my best. When there's a lot on the line and I'm building something that matters. The more projects on my plate, the more I want to take on. It's like a dopamine rush. Extra fuel to go even harder. When work is calm, I get distracted. Lose focus. If something comes up, I'm not really in the mood. Then it becomes stressful,…

We investigate whether LLMs internally encode problem difficulty in a way that aligns with human judgment, and whether this representation tracks generalization during reinforcement learning post-training. We train linear probes across layers and token positions on 60 models, evaluating…

πŸš€ Discover this insightful post from Hacker News πŸ“– πŸ“‚ Category: πŸ“Œ Key idea: My tutorial and take on C++20 coroutines Over the last 25 years, I’ve written a lot of event-driven code in C++. A typical example of event-driven code is registering a callback that gets invoked every time a socket has data to be read. Once you have read an entire message, possibly after many invocations, you parse the message and invoke another callback from a higher layer of abstraction, and so forth. This kind of code is painful to write because you have to break your code…
