The Tallest, Smallest, and Oldest Science of 2019

In 2019, scientists made groundbreaking discoveries across biology, physics, and geology. They found what might be the world's oldest fungus in Arctic Canada, dating back nearly a billion years. In physics, a new circuit was designed to detect the weakest possible radio signals using qubits, potentially enhancing technologies like MRI and radio astronomy. Geologists discovered massive underground peaks at the 660 km boundary in Earth's mantle, which could rival the Himalayas if on the surface. These findings highlight the continuous pursuit of understanding in science.

In what ways could the technology developed for detecting single photons be applied in the future?

What methods did scientists use to analyze the boundary in the mantle?

What implications do the findings about the Earth's mantle have for our understanding of tectonic plates?
