• Hacker News1Open hardware desktop 3D printing is dead?The article discusses how open hardware in 3D printing is facing challenges due to aggressive patent filings from Chinese companies since 2020. This includes patenting existing open-source designs and creating a complex legal environment that makes it difficult for small innovators to compete and share their work freely.Patent system and IP reform:Discussion of how IP/patent system is broken, favors wealthy, needs reform to be 100x cheaper/faster. Debate around whether patents should be weakened or eliminated vs protected. Chinese patent abuse highlighted as major concern.China's manufacturing dominance:How China has become unbeatable in hardware manufacturing through state backing, cheap costs, fast iteration.

• 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
