The Food and Drug Administration (FDA) has announced the release of a final guidance document titled "Mouse Embryo Assay for Assisted Reproduction Technology Devices." This guidance provides recommendations on conducting the mouse embryo assay (MEA), which is used to evaluate the potential for embryotoxicity of devices that come into contact with gametes and/or embryos. The FDA has revised the guidance based on public comments and has made several technical clarifications. The document emphasizes that following FDA guidelines is not mandatory and alternative approaches are acceptable if they meet relevant requirements.

The Environmental Protection Agency (EPA) finalized its review under the Clean Air Act for perchloroethylene (PCE) dry cleaning facilities' emission standards but did not make changes to current regulations. This decision follows the Toxic Substance Control Act's recent rule to phase out PCE use in dry cleaning over the next ten years, starting with a ban on new machines and ending with a full phase-out. The EPA opted not to require additional controls because of this phaseout, rendering further revisions unnecessary. The action will not impact existing requirements and is not expected to significantly affect most dry cleaners economically.

The Networking and Information Technology Research and Development (NITRD) Program is organizing public meetings throughout 2021. These meetings are facilitated by the Joint Engineering Team (JET) and the Middleware And Grid Interagency Coordination (MAGIC) Team. They provide a platform for people to engage with federal agencies and participate in discussions about research and technological developments. Interested individuals can find meeting details and sign up for updates via the NITRD website or their mailing lists. Public comments are encouraged and may be submitted for consideration.

The Maritime Sustainment and Technology Innovation Consortium (MSTIC) has updated its membership as of April 9, 2025. Various organizations have been added, including Connecticut Center for Advanced Technology, Inc. in Connecticut, and Velo3D, Inc. in California, while others, like Progeny Systems LLC in Virginia, have withdrawn. These changes were filed under the National Cooperative Research and Production Act of 1993 to limit antitrust liabilities. MSTIC plans to continue updating its membership and disclosing any further changes.

The Environmental Protection Agency (EPA) issued a correction to a previous rule document related to hazardous air pollutants and dry cleaning facilities. The correction is about a date listed in the document. Originally, the date was mistakenly written as "January 7, 2024" and should be "January 7, 2025". This correction ensures the rule reflects the correct year for compliance or reference.

The NITRD Joint Engineering Team (JET) and Middleware And Grid Interagency Coordination (MAGIC) Communities of Practice hold public meetings throughout 2025, providing opportunities for interaction between federal agencies and the public. These meetings, facilitated by the National Science Foundation, focus on sharing information about research and technology development. Interested individuals can participate in these meetings, which will be available via Zoom, and can sign up for notifications or submit comments through designated email addresses. Meeting details, including dates and agendas, are posted on the NITRD Public Meetings webpage.

The Federal Communications Commission (FCC) is seeking additional information about allowing direct communication between unlicensed client devices in the 6 GHz band. Currently, these devices must connect through an access point, but comments are being invited on whether a limited form of device-to-device communication should be permitted. Apple, Broadcom, and others suggest allowing direct communication if the devices can receive a certain signal from a low-power indoor access point. The FCC wants to know how this setup might work without causing interference to licensed services and is considering different technical requirements and safeguards.

The Maritime Sustainment Technology and Innovation Consortium (MSTIC) has updated the Department of Justice and the Federal Trade Commission about changes in its membership. New members include various companies and institutions like Amaero Advanced Materials and Manufacturing, Inc. and Carnegie Mellon University. These notifications are part of a process to limit the amount antitrust plaintiffs can recover in certain legal circumstances. MSTIC remains open to new members and will continue to report changes as they occur.

The Networking and Information Technology Research and Development (NITRD) Program, supported by the National Science Foundation, holds public meetings throughout 2021. These meetings are conducted by the Joint Engineering Team (JET) and the Middleware And Grid Interagency Coordination (MAGIC) Team, providing an opportunity for sharing information among Federal agencies and the public. Meetings are announced 30 days in advance, with participation possible via WebEx or teleconference. Public comments can be submitted and will be publicly available under the Federal Advisory Committee Act.

The Federal Aviation Administration (FAA) has issued a final rule regarding the airspace around the Tri-County Regional Airport in Lone Rock, Wisconsin. This rule revokes the Class E surface airspace designation at the airport and revises the Class E airspace extending from 700 feet above the ground. The changes are due to the decommissioning of a navigation aid, and they update geographic coordinates to match the FAA's database. The rule is not expected to significantly impact the environment or have major negative consequences.
