• Hacker News1Typst: A Possible LaTeX ReplacementTypst is a new document typesetting program designed as a modern replacement for LaTeX. Created by two German developers starting in 2019, it offers faster compilation, simpler markup syntax similar to Markdown, better error messages, and integrated programming capabilities while producing output quality comparable to LaTeX.Typst vs LaTeX performance and ease of use:Users report massive performance gains with Typst, including 3-4x faster compile times and instant compilation vs 18 minutes for large documents in LaTeX. The developer experience is significantly better with clearer error messages, simpler syntax, and less debugging required.Academic adoption challenges:The main barrier to Typst adoption in academia is the lack of journal and publisher support. Researchers need LaTeX templates for submissions, and switching requires creating new templates and getting institutional acceptance before broader adoption can occur.Document authoring workflows:Many users employ hybrid approaches, writing in Markdown/reStructuredText and converting to LaTeX, or starting with simpler formats before moving to LaTeX for final formatting. Typst eliminates this need by being approachable for both writing and programming.
• Reddit science1Using 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.Using scented products indoors, such as flame-free candles and wax melts, can create significant indoor air pollution comparable to car exhaust. Research by Purdue University found these products release nanosized particles that can penetrate deep into lungs and potentially enter the bloodstream, posing serious respiratory health risks.Misleading title scope:Discussion about how study only focused on wax melts but title suggests all scented products, with debate about whether findings could logically extend to other scented itemsHealth concerns from chemist:A chemist's perspective against using scented products leads to sharing of personal health impact stories, from COPD to cancer cases, and debate about necessity of artificial scentsAir purification solutions:Discussion of HEPA filters and other air purification methods as solutions, with debate about effectiveness against different types of pollutants like VOCs and nanoparticles
