Why is Canada threatening retaliation over the 50% U.S. tariffs?
Live from NPR News in Washington, I'm Dan Ronan. Canada's Prime Minister Mark Carney says his country will retaliate against the fifty percent tariffs imposed by the White House on Canadian products. As Dan Karpinchuk reports, the move comes after talks aimed at heading off those levies collapsed last night just before the deadline.
Prime Minister Kearney says the new fifty percent tariffs amount to an economic attack on Canada, and he is vowing retaliatory tariffs on U.S. goods dollar for dollar starting September eighth.
Unacceptable.
Carney also says the US wanted changes to auto tariffs and to restrict Canadian protections of language and culture, and in effect, sovereignty. Most provincial premiers say they support Kearney's decision not to sign a bad deal for Canada. For NPR News, I'm Dan Karpinchuk in Toronto. No new talks or schedules.
How did a federal judge rule on the Trump administration’s visa ban?
Scheduled. A federal judge says the Trump administration acted illegally when it started processing immigrant visas for citizens of seventy five countries, including Afghanistan, Brazil, and Yemen. The State Department had said visa applicants from those nations were likely to need public assistance if they came to the U.S. NPR's Michael Copley reports.
U.S. District Judge Jeanette Vargas struck down the Trump administration's visa ban in part because she said it discriminated on the basis of nationality, in violation of federal immigration law. Under the Immigration and Nationality Act, consular officers are barred from issuing visas to people who are unlikely to be able to support themselves in the U.S., but that determination has to be made on a case by case basis. Judge Vargas said the visa ban overrode the discretion of consular officers. Officers. The judge also set aside any visa denials that were based solely on the ban.
What sparked the latest deadly clashes between Russia and Ukraine?
Neither the State Department nor the White House immediately responded to a request for comment. Michael Copley, NPR News.
The latest exchange of attacks in Russia and Ukraine today killed at least ten people. The fresh fighting comes a day after Russia bombed a shopping center that killed at least sixteen people and wounded more than one hundred thirty others. As NPR's Charles Maines reports from Moscow, the fighting in recent days has stepped up between the two countries.
The Russian attack took place in the Ukrainian city of Kriviri and amounted to a double tap. One drone hit them all during peak business hours, followed by a second tap after rescuers arrived on the scene. Ukrainian president Vladimir Zelensky denounced the tactic as despicable and vowed a response that appears to have come in several waves. In Russia's Krasnodar region, authorities said two children died amid Ukrainian drone strikes on a town on the Azov Sea. Ukraine also continued its targeting of energy and logistics centers, this time hitting an oil facility and retail warehouse in the Samara region.
How are five‑year‑old brain organoids changing neuroscience research?
Charles Maynes, NPR News, Moscow.
This is NPR. Human brain development remains one of the most complex mysteries in biology. A new study out this week in the journal Nature shows that tiny clumps of human cells could one day help solve that mystery. NPR's Rachel Carson reports
Organoids are tiny clusters of human cells grown in labs. Scientists use them to study human brain development. But organoids usually last for months, maybe a year. That means they only show researchers very early stages of the human brain. But for this new study, scientists managed to make some organoids grow for five years. Dr.
What does the new Colorado River plan mean for water supplies in the Southwest?
Goli Ming is a neuroscientist at the University of Pennsylvania. She wasn't involved in this study, but says it's the longest lifespan of organoids to date. This is a technology breakthrough. During this time, the organoids matured to show characteristics of a four-year-old human brain. Ming says this means researchers could potentially use organoids in longer term developmental studies. Rachel Carlson, NPR News.
A new plan to manage the water supply from the shrinking Colorado River will mean big cuts for the water supply in the states of Arizona with California and Nevada also expected to get less water.
