Despite being tiny, cyanobacteria have a disproportionately large impact on the ecosystem. Kyle Frischkorn, a member of the Simons Collaboration on Ocean Processes and Ecology, describes the efforts to uncover the secret lives of diverse and remarkable microbes.
The study relates to the theory that our bodies co-evolved with bacteria over millions of years. Over that time, microbes gradually came to help regulate bodily processes from digestion to energy processing to immune defenses.
The road to discovery is littered with judgment calls, educated guesses and assumptions. Some scientists, especially in physics and astronomy, have come to embrace a system of thinking that lays all the subjective laundry out — it's called Bayesian statistics.
In this oral history video, Dick Karp, founding director of the Simons Institute for the Theory of Computing, discusses some of the key developments in theoretical computer science during his long and distinguished career. He stepped down as director at the end of 2017.
