Nature's Hidden Signals

Trees may act as large antennas capable of picking up radio waves, but the complexity of their structure requires further study. Meanwhile, star dunes, massive pyramidal formations found on Earth and other celestial bodies, can be dated using quartz grains that store solar energy. A recent discovery in Morocco revealed a 13,000-year-old star dune, showcasing the innovative methods scientists use to extract and analyze samples without exposure to light.
