Trump Clears US For Supersonic Flights Ending +50 Year Ban

“President Trump has issued an executive order ‘leading the world in supersonic flight’ which requires the Federal Aviation Administration to remove restrictions on supersonic flights within U.S. airspace. The existing noise rules have been in place since 1968, and a corresponding FAA restriction on flights exceeding Mach 1 established in 1970. These rules previously prevented Concorde operations on transcontinental flights.

The FAA has reviewed this rule in recent years but made no changes to the overland flight restriction. The new Trump executive order requires the FAA to repeal its ‘prohibition on overland supersonic flight, establish an interim noise-based-certification standard, and repeal other regulations that hinder supersonic flight.’

The FAA would need to repeal the prohibition on overland supersonic flight in 14 CFR 91.817 within 180 days and issue a Notice of Proposed Rule Making to establish a standard for supersonic aircraft certification within 18 months of the order.”

New FCC Rules Could Drastically Improve Starlink Capacity

“The Federal Communications Commission (FCC) voted on Thursday [4/30/26] to modernize its satellite spectrum-sharing rules, which could increase capacity for space-based broadband services by up to sevenfold…

The recent announcement comes as a revamp of the Equivalent Power Flux Density (EPFD) framework, developed in the late 1990s. The original framework was designed to prevent radio signal interference caused by satellites in low-Earth orbit, or non-geostationary orbit (NGSO), from affecting higher-orbiting geostationary satellites (GSO). As a result, it limited the amount of energy transmitted by satellites in low-Earth orbit to ground-based equipment, thereby slowing broadband speeds for consumers.”

First Malaria Drug for Babies Is Approved in Major Milestone

“The first malaria treatment for babies has been approved by the World Health Organization, opening the door to widespread use around the globe.

In parts of Africa, up to 18% of children under six months will be infected with malaria, but there has historically been no safe treatment for the smallest of them. There were 610,000 deaths from malaria in 2024, about three quarters of which were under-fives in Africa…

Medical leaders hope that Coartem Baby, which can be used to treat infants as small as 2kg (4.4lb), will fill the treatment gap. The drug comes as sweet cherry-flavoured tablets that can be dissolved into liquids, including breast milk…

Coartem Baby now has WHO prequalification, which indicates it meets international standards of quality, safety and efficacy, and will enable public-sector procurement for many countries with high rates of malaria, particularly in sub-Saharan Africa.”

NRC Unveils New Path for High-Volume Microreactor Licensing

The U.S. Nuclear Regulatory Commission (NRC) has proposed a sweeping new licensing framework designed to push microreactors out of the lab and onto the grid at unprecedented speed. The proposed rule, called Part 57, is paired with a broader agency overhaul that earlier this year created the Office of Advanced Reactors (OAR), headed by longtime NRC official Jeremy S. Bowen. Together, the two moves represent the most significant shift in U.S. nuclear regulation in a generation—a direct response to White House Executive Order 14300 (Ordering the Reform of the Nuclear Regulatory Commission) and the bipartisan Accelerating Deployment of Versatile, Advanced Nuclear for Clean Energy (ADVANCE) Act.

Announced April 24, the proposed Part 57 rule creates a streamlined, risk-informed pathway for licensing microreactors and other reactors with comparable risk profiles. The NRC and industry estimate it will save between $3.76 billion and $11.84 billion, depending on discount rate, largely by ‘reducing exemption requests and streamlining reviews.’ Construction permit and operating license timelines could shrink to six months to a year.”

California Salmon Population Rebounds, Fishing Open Again

“Federal fishery managers voted Sunday to open waters off the coast of California to commercial salmon fishing for the first time since 2022, with the population rebounding after wet winters ended a long drought.

The decision by the Pacific Fishery Management Council to allow limited commercial and recreational salmon fishing off the coast is a win for the state’s salmon fishing industry, which has grappled with years of season closures due to dwindling fish stocks. The council, which manages fisheries off the West Coast, barred commercial salmon fishing off California for the past three years. It voted last year to allow some recreational fishing for the first time since 2022.”
