Science Discoveries of 2019

In 2019, scientists made groundbreaking discoveries in biology, physics, and geology. They found what might be the world's oldest fungus in Arctic Canada, designed a circuit to detect the weakest possible radio signal, and discovered massive underground peaks in Earth's mantle. These findings help us understand the history of life on Earth, improve technology, and explore the planet's inner layers.
