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:

In-brief analysis

September 11, 2025

Data source: Natural Gas Intelligence
Note: Prices are adjusted for inflation based on June 2025 Bureau of Labor Statistics’ Consumer Price Index data.

Monthly average natural gas spot prices in the northwestern United States reached historic lows in 2025, as ample supply from Canada coincided with subdued regional demand for natural gas-fired electricity. At Northwest Sumas, a key pricing hub for natural gas in the U.S. Pacific Northwest, the daily spot price averaged $1.59 per million British thermal units (MMBtu) in 2025 through August and reached its lowest ever monthly average price of $0.56/MMBtu in June, according to data from Natural Gas Intelligence. The monthly average price for the first eight months of this year is the lowest for this period of any year since at least 1999, and it is about
