"A New Leaf" The cultivation of coca, the main ingredient in cocaine, has nearly tripled over the past five years in Colombia. As part of the 2016 peace agreement between the government and the Revolutionary Armed Forces of Colombia (FARC), the country has embarked on a unique experiment to try and end coca farming and production, but freeing Colombia from its cocaine problem is proving difficult. Charlet Duboc travels to the remote towns where coca farming is a way of life to examine the struggle for a cocaine-free Colombia. "Quantum Supremacy" Computer giants are racing to build the first quantum computer, a device with millions of times more processing strength than all the computers currently on Earth combined. This technology will harness the unusual laws of quantum mechanics to bring unimaginable advances in fields like materials science and medicine, but could also pose the greatest threat to cybersecurity yet. Taylor Wilson meets the scientists at the cutting edge of this new age of computing.
