When spring arrives and the heating season comes to an end, keeping warm becomes less of an issue. However, scientists remind us that it is not just a seasonal necessity – heat is also a valuable energy resource that can be stored and used when needed most. Researchers at Kaunas University of Technology (KTU) have discovered an innovative solution beneath our feet: using soil as an efficient thermal energy storage system.

The core of multispectral compatible camouflage technology lies in multispectral modulation, which requires the design of spectral characteristics based on the operational bands and principles of detectors. The intrinsic properties of natural materials depend on the inherent attributes of their microscopic components (e.g., molecules, atoms) and their arrangement, limiting their ability to modulate electromagnetic fields and making arbitrary tuning according to practical needs difficult. As a two-dimensional form of metamaterials, metasurfaces overcome the optical limitations of natural materials by designing artificial unit structures at a microscopic scale with periodicities between microscopic particles and operational wavelengths, enabling the modulation of macroscopic physical properties. Leveraging the metasurface's ability to flexibly control the amplitude and phase of electromagnetic waves, subwavelength structures can be designed on demand across different bands, providing critical support for the development of multispectral-compatible camouflage technologies. Ideal photoelectric camouflage materials must maintain compatibility with various detectors across the full spectrum while ensuring structural simplicity and ultrathin characteristics to reduce fabrication complexity and enhance practicality. However, a challenging contradiction exists between multifunctional multispectral integration and structural simplicity: whether in one-dimensional photonic crystals or metasurfaces, increasing the number of tunable bands often relies on multilayer stacking or complex configurations, significantly escalating design and fabrication difficulties.

The National Comprehensive Cancer Network (NCCN)—an alliance of leading cancer centers—celebrated 30 years of helping people with cancer to live better lives during the NCCN 2025 Annual Conference, March 28-30 in Orlando, Florida. The yearly event brings together leading minds and subject matter experts in front of a multidisciplinary audience to share the latest recommendations for cancer treatment and prevention.
