Need To Know
Trade Talks Collapse
The trade dispute between the US and Canada escalated sharply over the weekend after last-minute negotiations ended without agreement. A raft of US tariffs on Canadian goods kicked in Friday at midnight, while Prime Minister Mark Carney announced Canada would apply dollar-for-dollar tariffs going into effect Sept. 8.
The new US tariffs apply a 50% levy to about $20B in Canadian imports, or roughly 5% of the goods exported to the US. Items range from alcohol to agricultural products but exclude energy-related goods (full schedule in the first three links here). Carney said the retaliatory tariffs would be equal in monetary value, with specific items listed in the coming days.
Both countries and Mexico signed a free-trade agreement replacing NAFTA during President Donald Trump’s first term. Trump declined a 16-year extension in July, switching to an annual review (see an analysis of issues).

Anthony Retrial Denied
A Texas judge rejected Karmelo Anthony’s request for a new trial Saturday following his conviction in the murder of 17-year-old Austin Metcalf. The case drew national attention over the issue of race, even as both legal teams sought to downplay its role in the violence.
Nineteen-year-old Anthony, who is Black, received a 35-year prison sentence for fatally stabbing Metcalf, who was white, at a high school track meet in April 2025. Anthony’s team says he acted in self-defense, while prosecutors say Anthony initiated the altercation and pulled a knife. Since the trial, Anthony’s supporters have questioned courtroom conduct, evidence, and the jury’s racial makeup. A recent hearing uncovered both teenagers’ disciplinary records that weren’t previously acknowledged due to an informal agreement between the legal teams. The court recused the original judge after Anthony’s team questioned his impartiality over comments he made about the trial (watch the full interview).
Anthony's lawyers have appealed the decision.

Robot Race Returns
A Chinese-made robot defeated Jamaican athlete Usain Bolt's 100-meter sprint record Saturday, crossing 109 yards in 9.39 seconds, below Bolt’s 9.58 seconds. The showmanship was part of China’s second annual World Humanoid Robot Games in Beijing. Watch the moment here, after which the robot slams into a padded wall and collapses (via YouTube).
More than 2,000 humanoid robots are participating in this year’s Olympics-style games, with matches including racing, fighting, table tennis, and soccer. There are also more practical competitions, including contests on industrial assembly, packing, and tool manipulation. China leads the world in humanoid robot production, responsible for more than 80% of global shipments. The country has already begun replacing human workers on some domestic assembly lines and food delivery services, though robots have not yet been widely adopted.
The competition comes weeks after the US banned imports of foreign-made humanoid robots, citing national security concerns. See analysis on how China's approach to AI differs from the of the US.
