In the version of this article originally published, in the penultimate paragraph, the name of the Monash University scientist was misspelled; the correct spelling is Colin Pouton. In addition, the statement in paragraph 2 β€œthe SSCC, which is being supported by the same group that funded ESI, the Agency for Science, Technology and Research (A*STAR)” is incorrect. ESI is not funded by A*STAR. Its major investor is Bio-One Capital, a venture capital fund controlled through the Singapore Government's Economic Development Board. The SSCC is funded by A*STAR.
