Live from NPR News in Washington, I'm Janine Herbst. The U.S. and Iran held face-to-face peace talks in Pakistan today, with Vice President Vance leading the U.S. delegation as the fragile temporary ceasefire continues. President Trump says the talks are going well. I'm getting a lot of reports. They've been meeting for many hours, as you probably have noticed. We'll see what happens. Look, regardless, we win. Regardless what happens, we win. Speaking there as he left the White House to go to Florida, meanwhile the U.S. sent warships through the Strait of Hormuz today, and P.O.'s Franco Ordonez has more. Two U.S. Navy guided missile destroyers passed through the Strait of Hormuz today. Now this would mark the first transit of American warships since the start of the war, which began six weeks ago. The U.S. says this is the start of a process of reopening the Strait to commercial shipping. NPR's Franco Ordonez reporting. Around 20% of the world's oil transits through that Strait. The U.S. court of international trade heard arguments this week, in a case challenging President Trump's authority to impose sweeping new tariffs. NPR's Windsor-Johnston reports the lawsuit was brought by two dozen states and several businesses. That issue is President Trump's use of a 1974 trade law to justify the measures. The law allows temporary tariffs during a financial emergency tied to international trade imbalances. Ilya Somen is a law professor at George Mason University. He tells NPR the Constitution puts tariff authority squarely in the hands of Congress. The president has no independent power in this area of his own. He only has such authority as Congress has given him, and here they have not given him the kind of vast sweeping authority he's claiming. The outcome of the case could determine how far a president can go in reshaping trade policy without congressional approval. Windsor-Johnston, NPR News, Washington. This year's RSV season is lasting longer than usual, prompting most states to extend the window for immunizing babies against the dangerous respiratory virus. The respiratory sensitial virus, or RSV, is still spreading widely throughout the country, even though the virus has usually begun to fade by this time of year. In response, 48 states and jurisdictions have extended the period that babies can get immunized against the virus for free through a federal program until at least the end of April. That's according to the Association of Immunization Managers. RSV usually causes mild cold-like symptoms for most people, but the virus can cause serious complications for very young babies. In fact, it's the leading cause of hospitalizations for infants. Rob Stein, NPR News. This is NPR News. The four crew of the Artemis II lunar mission are now in Houston, where they got a big welcome from the NASA team on Earth. NASA Johnson Space Center director Vanessa Weisch says the mission was important. For the very first time, Orion's life support systems were tested with astronauts on board, an essential mission milestone for deep space when we go there, further and further ahead. The crew were the first humans to travel toward the Moon in more than 50 years, and they set a new record for the farthest distance any human has ever traveled from Earth after a fly by of the far side of the Moon. A new analysis finds Emperor Penguins are at risk of extinction. Imperial's Nate Roth reports melting sea ice and changing food availability are causing their decline. The world is getting warmer thanks to human activities, and temperatures at the poles are rising significantly faster than the global average. Hotter temperatures means less sea ice, and for Emperor Penguins, which rely on sea ice for breeding in his places to rest, it means fewer penguins are surviving. Twice in recent years, the ice has broken up early, causing thousands of chicks to drown in the frigid water. The International Union for the Conservation of Nature says Emperor Penguins are now considered to be endangered. Antarctic fur seals as well. Scientists involved in the analysis say urgent action is needed to reduce climate warming pollution. Nate Roth, NPR News. And I'm Janine Herbst, and you're listening to NPR News from Washington.
