Students build giant antenna to explore far reaches of Earth’s atmosphere

Undergraduates at the University of Hawaiʻi at Mānoa were inspired to build a giant antenna to explore hundreds of miles above the planet. The antenna, known as an ionosonde, project began after a lecture from atmospheric sciences Professor Giuseppe Torri about phenomena that can occur in the ionosphere, one of the highest layers of the Earth’s atmosphere. The ionosphere …

For healthy reefs, productive watersheds, resource managers are turning to AI

Artificial Intelligence (AI) is changing the way we work–not just for chatbots in customer service or conjuring fake images. AI excels at repetitive and redundant tasks; it can increase workflow efficiency and speed up data analysis. These types of tasks are not limited to office work; even the work of protecting natural resources from invasive …
