Ars Technica reports: Cities and counties around the U.S. are angry at the Trump administration over a proposal to override local rules that govern the deployment of wired broadband networks... The Federal Communications Commission [FCC] argues that too many local governments "excessively delay approvals and seek to extract exorbitant sums from providers, resulting in costs that render some deployments infeasible." The FCC plan is supported by broadband providers, but local governments told the FCC that it would override rules that protect public safety. Local governments say the plan is illegal and that the FCC should instead focus on how Internet providers thwart competition with permit-hoarding and other tactics that prevent competitors from deploying networks... They object to FCC plans to impose a 120-day deadline for processing permits and to proposed limits on fees and compensation that local governments can require from providers... Another filing submitted by the League of California Cities said the FCC has no authority to adopt the proposal. "Federal preemption of traditional state and local authority over public property, construction, public safety, permitting, and rights-of-way management should rest on clear congressional authorization," the filing said. "The commission should not infer broad preemptive authority where Congress did not expressly provide it...." A filing by Minnesota cities said the current FCC is making the same mistake it made during the first Trump administration, when its attempt to preempt state net neutrality laws was blocked in court... If the FCC finalizes its new preemption plan, city and state governments could sue and ask a court to rule that the agency exceeded its authority... Democratic Commissioner Anna Gomez approved the step of asking the public for input but signaled she would vote against the final proposal. "I am dubious about the commission's authority under Section 253 to use rulemaking to preempt states and localities when it comes to their management of rights of way and fees charged to providers," she said.

More than 200,000 barrels of low-level radioactive waste were stored on the floor of the Atlantic Ocean between 1949 and 1982, reports ScienceAlert. Whatever happened to those barrels? Scientists have descended to the wreckage in a crewed submersible to investigate — and found many of the barrels corroded and degraded, their contents spilling across the seafloor. Surprisingly, this isn't necessarily a subversion of the original plan... The International Atomic Energy Agency recommends that low-level waste be disposed of in robust containment in isolation for at least a few hundred years — but back in the mid-20th century, the recommendations were a little different. The contemporaneous guidelines recommended that containers needed to reach the seafloor intact and remain sealed only long enough for the short-lived radionuclides to decay. After that, the remaining waste was expected to slowly escape and disperse through the surrounding ocean. Not everything in the barrels would conveniently decay away, however. They contained a radioactive hodgepodge, including cesium-137, plutonium isotopes, and tritium, some of which can persist for thousands of years... [A] few years ago, nuclear engineer Patrick Chardon and marine geologist Javier EscartÃn of the French National Center for Scientific Research started to wonder what had become of the dumped waste. That question eventually became NODSSUM — Nuclear Ocean Dump Site Survey Monitoring — an interdisciplinary project bringing together nuclear physics, geology, oceanography, biology, and marine chemistry to find the barrels and investigate what, if anything, they were doing to the surrounding environment.... [T]he barrels also appeared to function as tiny oases on the otherwise sparsely populated sandy seafloor. Anemones had attached themselves to the barrels. Sponges, sea cucumbers, fish, and crustaceans lived around them, with crabs apparently particularly fond of the artificial shelters... Instruments aboard the ship detected significant signals of cobalt-60 and niobium-94, which the researchers could specifically link to the dumped waste... [Samples are now being analyzed] There is precedent, however, to suggest that even striking levels of radioactivity around a source don't necessarily spread very far. A recent study of the sunken Soviet submarine Komsomolets found radionuclide levels hundreds of thousands of times above background immediately around the leaking reactor — but those levels dropped sharply within just a few meters as the material dispersed through the seawater. The NODSSUM team similarly found that, despite the significant radioactive signals around the barrels, activity levels weren't high enough to pose major radiation-protection problems for the scientists handling the samples. [Their three-person submersible] Nautile and the instruments it carried showed no signs of contamination. The real achievement was mapping the exact location of the barrels. "None of this means the waste is harmless," the article concludes — but it also doesn't mean we're about to be overrun by radioactive crabs."
