Since taking office, US President Donald Trump has thrown American science and medical research into disarray.

Through a flurry of executive orders, he withdrew the US from the World Health Organization, imposed a communications blackout on the Centers for Disease Control and Prevention and ordered the removal of publications, guidelines and databases “that inculcate or promote gender ideology”.

Thousands of government webpages were taken offline, erasing references to gender, race and sexual orientation.

The impact is spreading to Australian medical researchers, whose concerns range from losing their access to funding, the censorship of their findings and the disruption of global health alert systems.

Today, science journalist and contributor to The Saturday Paper Bianca Nogrady, on America’s ideological war on science and the implications for Australia.
