A collection of small antennas can amplify and control polarization in any direction
A new polarization-independent, highly resonant metasurface directs incoming light (top left) and allows accurate amplification and control of light without the need to move in a specific direction. Credit: Bo Zhao Antennas receive and transmit electromagnetic waves, and distribute information to radio, television, mobile phones, etc. Researchers at McKelby’s Faculty of Engineering at Washington University in St. Louis imagine a…

Hurricane Helen drone flight breaks data collection and flight time records
S0 Drone Sensors, Components, and Hardware. Credit: Black Swift Technologies As Hurricane Helen formed in the Gulf of Mexico, NOAA researchers collected critical data from the sea and air to better understand tropical cyclones and support forecasters at the National Hurricane Center. This real-time data gives meteorologists a clearer picture of the storm environment and structure, reducing forecast uncertainty. Researchers…

New microchip captures exosomes, enabling faster and more sensitive lung cancer detection from blood collection
The twisted disc shape of gold nanoparticles creates chirality, or asymmetry, and ensures strong interaction with light. A cavity in the center, less than 100 nanometers wide, helps the nanoparticles trap exosomes. Credit: University of Michigan A new method for diagnosing lung cancer by drawing blood is 10 times faster and 14 times more sensitive than previous methods, according to…
