Dr. Unwins, a young geologist in Queensland, may have discovered the most important biological finding of the past century. Her microscopic "nanobes," ten times smaller than any known living thing, could unlock the secrets of life's origins. These tiny organisms appear to consume plastic, possibly originated from space, and have been linked to cancer. First discovered in 1998 in petroleum samples, these resilient entities survived for millions of years deep within the Earth. When given oxygen and nutrients, they grow, reproduce, form colonies, and contain DNA – the fundamental building blocks of life.
