From the closer-look department: New Mexico's legislature passed bills last week that would ban consumer products containing PFAS, joining a small but growing number of states taking action against these persistent "forever chemicals." If signed by the governor, the legislation would prohibit the sale of many products with added per- and polyfluorinated alkyl substances (PFAS) in New Mexico, making it the third state after Maine and Minnesota to enact such comprehensive restrictions.
At least 29 states have PFAS-related bills before state legislatures this year, according to Safer States, a network of advocacy organizations. Research shows PFAS accumulate in the environment and human bodies, potentially causing health problems from high cholesterol to cancer. EPA figures indicate almost half of Americans are exposed to PFAS in their drinking water.
Wired reports that chemical and consumer products industries are aggressively fighting state-level bans on "forever chemicals" through lobbying and legal action as regulations spread across the United States. The Cookware Sustainability Alliance, formed in 2024 by major cookware manufacturers, has testified in 10 statehouses against PFAS restrictions and sued Minnesota in January, claiming its ban is unconstitutional. (The New Mexico bills include notable exemptions, particularly for fluoropolymers used in nonstick cookware, following successful lobbying by industry groups.)
Industry groups are also targeting federal regulators, with the American Chemistry Council and others recommending the EPA adopt a narrower definition of PFAS. "The federal regulatory approach is preferable to a patchwork of different and potentially conflicting state approaches," said Erich Shea from the American Chemistry Council.

From the how-about-that department: AmiMoJo writes: The Shenzhen 8K UHD Video Industry Cooperation Alliance, a group made up of more than 50 Chinese companies, just released a new wired media communication standard called the General Purpose Media Interface or GPMI. This standard was developed to support 8K and reduce the number of cables required to stream data and power from one device to another. According to HKEPC, the GPMI cable comes in two flavors -- a Type-B that seems to have a proprietary connector and a Type-C that is compatible with the USB-C standard.
Because 8K has four times the number of pixels of 4K and 16 times more pixels than 1080p resolution, it means that GPMI is built to carry a lot more data than other current standards. There are other variables that can impact required bandwidth, of course, such as color depth and refresh rate. The GPMI Type-C connector is set to have a maximum bandwidth of 96 Gbps and deliver 240 watts of power. This is more than double the 40 Gbps data limit of USB4 and Thunderbolt 4, allowing you to transmit more data on the cable. However, it has the same power limit as that of the latest USB Type-C connector using the Extended Power Range (EPR) standard. GPMI Type-B beats all other cables, though, with its maximum bandwidth of 192 Gbps and power delivery of up to 480 watts.

From the how-about-that department: The internet's physical mass remains contested among scientists, with estimates ranging from a strawberry to something almost unimaginably small. In 2006, Harvard physicist Russell Seitz calculated the internet weighed roughly 50 grams based on server energy, a figure that would now equate to potato-weight given internet growth.
Christopher White, president of NEC Laboratories America, has dismissed this calculation as "just wrong." White suggests a more accurate method that accounts for the energy needed to encode all internet data in one place, yielding approximately 53 quadrillionths of a gram at room temperature. Alternatively, if the internet's projected 175 zettabytes of data were stored in DNA -- a storage medium scientists are actively exploring -- it would weigh 960,947 grams, equivalent to 10.6 American males. Though scientists debate measurement methods, White asserts the web's true complexity makes it "essentially unknowable."
