In a breakthrough study published in Science Advances, researchers from the Technical University of Denmark and Universidad Politécnica de Madrid have developed a novel device called an acoustic rainbow emitter (ARE). This innovation can receive broadband white-noise signals from a point source—one that radiates sound equally in all directions—and scatter them so that individual sound frequencies are emitted in different directions. Much like how a prism disperses white light into a spectrum of colors, the ARE splits sound into its constituent frequencies, producing an “acoustic rainbow.” The concept is inspired by natural hearing systems, such as the complex ears of humans, bats, and dolphins, which have evolved passive structures capable of capturing and shaping sound with remarkable precision. Despite nature's elegance, replicating this level of broadband acoustic manipulation in artificial systems has proven difficult. Traditional sound control methods rely heavily on active components or resonance-based mechanisms, which are typically limited in bandwidth and spatial flexibility. https://github.com/AidenKLM/ATHENA-Blood-Twins-MOD-unlimited-diamonds-and-emeralds https://github.com/BlakeRNW/Dark-War-Survival-unlimited-rubies-MOD-2025 https://github.com/BradyTDN/Asphalt-8-unlimited-money-and-tokens-latest-version https://github.com/CalebGNS/Hill-Climb-Racing-unlimited-money-and-diamonds-and-paint-buckets-MOD https://github.com/CarterSNB/Motorcycle-Real-Simulator-unlimited-money-MOD-2025 https://github.com/ColeDSB/Extreme-Car-Driving-Simulator-unlimited-money-and-VIP-Pass-2025 https://github.com/ConnorDVS/Moto-Rider-GO-Highway-Traffic-unlimited-money-MOD-2025 https://github.com/DylanKMP/Balkan-Drive-Zone-unlimited-money-MOD-2025 https://github.com/EthanBKT/Car-Parking-Multiplayer-2-unlimited-money-and-gold-MOD-2025 https://github.com/PaulHMB/OTR---Offroad-Car-Driving-Game-unlimited-money-unlock-all-cars-2025 https://github.com/JakeGNT/NFS-No-Limits-unlimited-money-and-gold-MOD-2025 https://github.com/JaxonLVB/Cars-Arena-Fast-Race-3D-MOD-unlimited-money https://github.com/LeviAMT/Drift-2-Drag-MOD-unlimited-money-latest-version-2025 https://github.com/MasonBKT/Rally-Fury-unlimited-money-and-tokens-and-speed-MOD-2025 https://github.com/NathanKNW/Driving-School-Simulator-Evo-unlimited-money-2025 https://github.com/NolanGBT/Real-Racing-3-unlimited-money-and-gold-2025 https://github.com/ParkerGNS/Drift-Max-Pro-unlimited-money-and-gold-unlock-all-cars-2025 https://github.com/RyanHND/Driving-Zone-Germany-unlimited-money-MOD-2025 https://github.com/TylerGRT/Offroad-Outlaws-VIP-unlocked-unlimited-money-2025 https://github.com/DavidFND/Stunt-Car-Extreme-MOD-unlimited-money-and-gems https://github.com/TylerDVS/Rebel-Racing-unlimited-money-gold-and-keys-latest-version https://github.com/WadeTMD/Dyno-2-Race-unlimited-money-2025 https://github.com/ChrisGNW/My-Dream-Store-unlimited-money-and-gems-2025 https://github.com/AndrewTMD/Wasteland-Life-Survival-Idle-MOD-unlimited-money-and-gems https://github.com/ChrisPGN/Pizza-Ready-unlimited-money-and-gems-unlocked-everything-2025 https://github.com/MarkLTN/Top-Eleven-2025-unlimited-tokens-MOD https://github.com/KevinEMD/eFootball-2025-unlimited-coins https://github.com/TerryABD/Score-Hero-unlimited-money-and-life-2025 https://github.com/RobertGRT/Real-Boxing-2-unlimited-diamonds-MOD-2025 https://github.com/WilliamPTB/The-Grand-Mafia-MOD-unlimited-gold-2025 https://github.com/DavidFMW/Forge-of-Empires-MOD-unlimited-diamonds-2025 https://github.com/ThomasDTS/Static-Shift-Racing-unlimited-money-and-gems-2025 https://github.com/MatthewPRT/Ultimate-Car-Driving-2-2025-unlimited-money-MOD https://github.com/AndrewTNS/Drag-Racing-Streets-unlimited-money-MOD-latest-version https://github.com/BrianMWA/Hero-Wars-Alliance-unlimited-money-and-gems-latest-version https://github.com/KevinGCT/Shadow-Fight-4-Arena-unlimited-everything-and-max-level-MOD-2025 https://github.com/StevenBKN/Shadow-Fight-3-unlimited-gems-and-shadow-energy-MOD-2025 https://github.com/JoshBNG/Assoluto-Racing-unlimited-money-2025 https://github.com/KevinBKT/CarX-Highway-Racing-unlimited-money-MOD-2025 https://github.com/JeffreyTKT/Beach-Buggy-Racing-unlimited-money-and-gems-2025-MOD https://github.com/JasonGMB/Universal-Truck-Simulator-unlimited-money-2025-MOD https://github.com/PatrickDFK/Truck-Simulator-USA-Revolution-unlimited-money-MOD-2025 https://github.com/AdamFNG/APEX-Racer-unlimited-money-and-gold-MOD-2025 https://github.com/NathanWDN/F1-Clash-2025-unlimited-money-MOD https://github.com/ChrisJNK/Pocket-Champs-MOD-unlimited-money-and-gems-latest-version https://github.com/DavidHKD/Pocket-Styler-unlimited-money-and-gems-latest-version-2025 To overcome these challenges, the research team employed computational morphogenesis—a process that combines structural optimization algorithms and finite element analysis to create highly efficient forms. By leveraging tools like topology optimization, advanced wave modeling, and 3D printing, the researchers designed complex, solid-state structures capable of controlling sound in new ways. They used the Helmholtz equation to simulate how sound waves propagate and scatter in the presence of a rigid, sound-reflecting object. This modeling enabled them to fine-tune the shape of the structure to manipulate how different frequencies are dispersed. The result is a single-material passive device that can take incoming sound waves and split them into a directional spectrum based on frequency—essentially creating a rainbow of sound. In addition to the ARE, the team also developed a "lambda splitter," which separates low and high-frequency sound waves, sending them in opposite directions. Both devices function entirely through passive scattering—interactions between the material’s surface and sound waves—with no need for electricity or moving parts. These innovations show that carefully engineered passive structures can control sound with high precision, providing a low-energy alternative to traditional acoustic technologies.

Floating solar—installing solar panels on bodies of water—can generate more electricity per square foot than land-based solar, but its broader impacts on ecosystems, climate resilience, and community use are still not fully understood. A new study published June 13 in Cell Reports Sustainability offers a comprehensive framework to help guide the responsible implementation of this emerging technology. The research, led by postdoctoral researcher Adam Gallaher, highlights the significant energy potential of floating solar in the Northeastern United States while emphasizing the need to account for environmental and social trade-offs in siting decisions. https://github.com/AidenKLM/ATHENA-Blood-Twins-MOD-unlimited-diamonds-and-emeralds https://github.com/BlakeRNW/Dark-War-Survival-unlimited-rubies-MOD-2025 https://github.com/BradyTDN/Asphalt-8-unlimited-money-and-tokens-latest-version https://github.com/CalebGNS/Hill-Climb-Racing-unlimited-money-and-diamonds-and-paint-buckets-MOD https://github.com/CarterSNB/Motorcycle-Real-Simulator-unlimited-money-MOD-2025 https://github.com/ColeDSB/Extreme-Car-Driving-Simulator-unlimited-money-and-VIP-Pass-2025 https://github.com/ConnorDVS/Moto-Rider-GO-Highway-Traffic-unlimited-money-MOD-2025 https://github.com/DylanKMP/Balkan-Drive-Zone-unlimited-money-MOD-2025 https://github.com/EthanBKT/Car-Parking-Multiplayer-2-unlimited-money-and-gold-MOD-2025 https://github.com/PaulHMB/OTR---Offroad-Car-Driving-Game-unlimited-money-unlock-all-cars-2025 https://github.com/JakeGNT/NFS-No-Limits-unlimited-money-and-gold-MOD-2025 https://github.com/JaxonLVB/Cars-Arena-Fast-Race-3D-MOD-unlimited-money https://github.com/LeviAMT/Drift-2-Drag-MOD-unlimited-money-latest-version-2025 https://github.com/MasonBKT/Rally-Fury-unlimited-money-and-tokens-and-speed-MOD-2025 https://github.com/NathanKNW/Driving-School-Simulator-Evo-unlimited-money-2025 https://github.com/NolanGBT/Real-Racing-3-unlimited-money-and-gold-2025 https://github.com/ParkerGNS/Drift-Max-Pro-unlimited-money-and-gold-unlock-all-cars-2025 https://github.com/RyanHND/Driving-Zone-Germany-unlimited-money-MOD-2025 https://github.com/TylerGRT/Offroad-Outlaws-VIP-unlocked-unlimited-money-2025 https://github.com/DavidFND/Stunt-Car-Extreme-MOD-unlimited-money-and-gems https://github.com/TylerDVS/Rebel-Racing-unlimited-money-gold-and-keys-latest-version https://github.com/WadeTMD/Dyno-2-Race-unlimited-money-2025 https://github.com/ChrisGNW/My-Dream-Store-unlimited-money-and-gems-2025 https://github.com/AndrewTMD/Wasteland-Life-Survival-Idle-MOD-unlimited-money-and-gems https://github.com/ChrisPGN/Pizza-Ready-unlimited-money-and-gems-unlocked-everything-2025 https://github.com/MarkLTN/Top-Eleven-2025-unlimited-tokens-MOD https://github.com/KevinEMD/eFootball-2025-unlimited-coins https://github.com/TerryABD/Score-Hero-unlimited-money-and-life-2025 https://github.com/RobertGRT/Real-Boxing-2-unlimited-diamonds-MOD-2025 https://github.com/WilliamPTB/The-Grand-Mafia-MOD-unlimited-gold-2025 https://github.com/DavidFMW/Forge-of-Empires-MOD-unlimited-diamonds-2025 https://github.com/ThomasDTS/Static-Shift-Racing-unlimited-money-and-gems-2025 https://github.com/MatthewPRT/Ultimate-Car-Driving-2-2025-unlimited-money-MOD https://github.com/AndrewTNS/Drag-Racing-Streets-unlimited-money-MOD-latest-version https://github.com/BrianMWA/Hero-Wars-Alliance-unlimited-money-and-gems-latest-version https://github.com/KevinGCT/Shadow-Fight-4-Arena-unlimited-everything-and-max-level-MOD-2025 https://github.com/StevenBKN/Shadow-Fight-3-unlimited-gems-and-shadow-energy-MOD-2025 https://github.com/JoshBNG/Assoluto-Racing-unlimited-money-2025 https://github.com/KevinBKT/CarX-Highway-Racing-unlimited-money-MOD-2025 https://github.com/JeffreyTKT/Beach-Buggy-Racing-unlimited-money-and-gems-2025-MOD https://github.com/JasonGMB/Universal-Truck-Simulator-unlimited-money-2025-MOD https://github.com/PatrickDFK/Truck-Simulator-USA-Revolution-unlimited-money-MOD-2025 https://github.com/AdamFNG/APEX-Racer-unlimited-money-and-gold-MOD-2025 https://github.com/NathanWDN/F1-Clash-2025-unlimited-money-MOD https://github.com/ChrisJNK/Pocket-Champs-MOD-unlimited-money-and-gems-latest-version https://github.com/DavidHKD/Pocket-Styler-unlimited-money-and-gems-latest-version-2025 “Rather than focusing solely on where floating solar is cheapest and most efficient, we wanted to think holistically about the ecological and social value of waterbodies,” Gallaher said. “Our framework could also apply to other renewable technologies—it’s really about understanding how energy systems intersect with the landscape and what trade-offs we may face.” The team assessed the suitability of waterbodies across the region based on proximity to energy infrastructure and accessibility. They found that about 3.5% of existing waterbodies are both technically feasible and realistically usable for floating solar. They modeled four different deployment scenarios: • Utilizing all eligible waterbodies; • Avoiding waterbodies critical to biodiversity and climate resilience; • Preserving recreational water use; • A precautionary model excluding both biodiversity-sensitive and recreational sites. If all eligible sites were used, floating solar could meet 25% of the region's solar energy demand by 2050, offsetting the need for terrestrial solar entirely. Even under the most restrictive model—excluding biodiversity and recreational areas—floating solar could still supply 5% of the region’s needs, a nearly 200% increase from current terrestrial solar output. “That 5% is substantial,” said senior author Steven Grodsky, assistant professor of natural resources in Cornell’s College of Agriculture and Life Sciences. “It means thousands of acres of land could be spared while still making meaningful progress on clean energy goals.” In New York alone, floating solar could provide up to 55% of projected 2030 solar needs under full deployment, and 24% when biodiversity is protected. However, floating solar is not impact-free. In a related study, Grodsky’s team found that floating panels raised greenhouse gas emissions on small ponds by nearly 27%. This underscores the need for informed planning that weighs energy gains against possible environmental costs. “Freshwater is far more limited than land,” Grodsky noted. “We need to consider not just the benefits of floating photovoltaics but also the socioecological consequences, like effects on fish, water quality, and recreational use.” Accounting for these factors could also improve community support, which often determines whether projects are approved. “People care deeply about their local lakes and reservoirs,” Grodsky said. “If you ignore that and only model technical viability, you risk backlash. By integrating social and ecological data, we can make smarter, more sustainable decisions.”
