Scientists in Korea have engineered magnetic nanohelices that can control electron spin with extraordinary precision at room temperature. By combining structural chirality and magnetism, these nanoscale helices can filter spins without complex circuitry or cooling. The breakthrough not only demonstrates a way to program handedness in inorganic nanomaterials but also opens the door to scalable, energy-efficient spintronic devices that could revolutionize computing.

Synopsis

Wildland fire is a powerful force on the planet, one that is rapidly accelerating in complexity beyond our current understanding. A new approach is needed. This approach requires a proactive and scalable perspective that recognizes the variety and connectedness of components of wildland fire. Coordinated scientific research and education that enables large-scale, cross-cutting breakthroughs to transform our understanding of wildland fire is urgently needed. In an era of rapid change, our society needs forward-looking research built on new frameworks that will realign our relationship with wildland fire.

The Fire Science Innovations through Research and Education (FIRE) program invites innovative multidisciplinary and multisector investigations focused on convergent research and education activities in wildland fire. All areas of science, engineering, and education supported by the U.S. National Science Foundation are included in this program. Projects developed by a wide array of groups including, for example,

DENTON, Texas – Preliminary Flood Insurance Rate Maps (FIRMs) are available for review by residents and business owners in the cities of Bruceville-Eddy, Golinda, Lott, Marlin and Rosebud and the unincorporated areas of Falls County, Texas.

Property owners are encouraged to review the latest information to learn about local flood risks and potential future flood insurance requirements. Community residents can identify any concerns or questions about the information provided and participate in the appeal and comment periods for the maps.

This is Falls County’s first complete set of digital FIRMs. These maps serve multiple purposes, including defining Special Flood Hazard Areas (SFHAs). SFHAs are areas at high risk for flooding. Community leaders can use these maps to make informed decisions about building standards and development that will make the community more resilient and lessen the impacts of a flooding event.

FEMA stresses that flooding can and does happen outside of the most vulnerable areas.

Review the preliminary flood maps by visiting the local floodplain administrator (FPA). A FEMA Map Specialist can help identify community FPAs. Specialists are available by telephone at 877-FEMA-MAP (877-336-2627) or by email at [email protected].

The preliminary maps may also be viewed online:

CHICAGO – Preliminary flood risk information and updated Flood Insurance Rate Maps (FIRMs) are available for review by residents and business owners in Richland County within the Kickapoo River Watershed. Property owners are encouraged to review the latest information to learn about local flood risks and potential future flood insurance requirements. Community stakeholders can identify any concerns or questions about the information provided and participate in the 90-day appeal and comment period.

The 90-day appeal period will begin on or around September 18, 2025. The preliminary maps and changes from current maps may be viewed online at the FEMA Flood Map Changes Viewer: http://msc.fema.gov/fmcv

The updated maps were produced in coordination with local, state, and FEMA officials. Significant community review of the maps has already taken place, but before the maps become final, community stakeholders can identify any concerns or questions about the information provided and submit appeals or comments. Contact your local floodplain administrator to do so. 

Appeals must include technical information, such as hydraulic or hydrologic data, to support the claim. Appeals cannot be based on the effects of proposed projects or projects started after the study is in progress. If property owners see incorrect information that does not change the flood hazard information, such as a missing or misspelled road name in the Special Flood Hazard Area or an incorrect corporate boundary, they can
