The News story ‘How Trump’s science cuts could hurt his supporters’ (Nature 545, 273–274; 2017) misstated the number of advanced manufacturing institutes funded by the US government — there are 14, not 9. The graphic also gave the funding amounts in US$ instead of millions of US$.

The News Feature ‘The electric cure’ (Nature 545, 20–22; 2017) erroneously stated that Kevin Tracey initiated the first trial for vagus nerve stimulation in humans. In fact, the trial was started by SetPoint Medical. And Paul-Peter Tak, who ran the trial, first joined GlaxoSmithKline in 2011, not 2016.
