CHICAGO — U.S. President Donald Trump signed an executive order on Tuesday to bolster the use of artificial intelligence and provide an additional $50 million in research grants aimed at finding cures for childhood cancers, according to a White House official. The order builds on the National Cancer Institute’s Childhood Cancer Data Initiative, a 10-year, $500 million program announced by Trump during his 2019 State of the Union Address focused on gathering and sharing data on childhood cancers. The data initiative proposed $50 million in funding over 10 years. According to the World Health Organization, some 400,000 children from infants to age 19 are diagnosed with cancer worldwide each year.
