• Hacker News1Trump's global tariffs struck down by US Supreme CourtThe Supreme Court struck down Trump's emergency tariff powers in a 6-3 decision, ruling against tariffs imposed on global imports. Trump responded by announcing new 10% tariffs under Section 122 law, affecting countries with existing trade deals. The ruling creates uncertainty about refunds for businesses and impacts Trump's foreign policy tools, though he plans workarounds to maintain tariff revenue.Refunds and profit distribution:Discussion centers on whether companies that collected tariffs from consumers will refund the money or keep it as profit. Complex scenarios involve middlemen like Cantor Fitzgerald buying refund rights, while consumers who paid higher prices likely won't see their money back.Presidential power vs congressional authority:Debate over constitutional separation of powers regarding tariff authority. Many argue the Constitution clearly gives Congress power to levy taxes/tariffs, not the president, though some justices disagreed in a 6-3 ruling.Howard Lutnick conflicts of interest:Extensive discussion about Commerce Secretary Howard Lutnick's sons at Cantor Fitzgerald offering "tariff refund products" - paying companies 20-30% of potential refunds upfront, then collecting 100% when tariffs are struck down.
• 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
