Google is the dominant player in the $278.6 billion US digital-ad market, controlling most of the technology used to buy, sell and serve online advertising.

The US and Germany are poised to announce they’ll provide main battle tanks to Ukraine, a significant escalation that nevertheless offers Kyiv a powerful new weapon to counter Russian aggression and reaffirms unity among NATO allies. Germany had indicated it was unwilling to provide such tanks unless others acted as well. Meanwhile, the US has confronted China’s government with evidence that state-owned companies are backing Russia’s war.

US public health chief Rochelle Walensky continued reconfiguring her agency to fight crises after criticism of its Covid-19 response. The Centers for Disease Control and Prevention created new offices on health equity and said it aims to shore up gaps in monitoring for potential threats.

In Japan, getting divorced is relatively simple, but issues of custody and visitation can last for years—and sometimes carry extreme consequences. Child welfare in failed Japanese marriages often turns on single-parent custody, where the other parent is largely excluded from a child’s life.
