City of Lions – Hospitals, health care facilities, and ambulances in Ukraine have been under attack in recent weeks. Since the start of the conflict, there have been more than 70 attacks on hospitals, doctors, and ambulances, according to the World Health Organization. Medical facilities are quickly running out of vital medical supplies like oxygenators, blood transfusion equipment, and PPE. The International Medical Corps (IMC) has plans to intervene. Scott Pelley embeds with the IMC as they deliver much-needed supplies, training, and resources into Ukraine. The "City of Lions" is the nickname for Lviv, Ukraine. Londongrad – One of the ways the West is hoping to derail Vladimir Putin's invasion of Ukraine is by waging war on his inner circle: the hundreds of mega-rich oligarchs who hide Putin's money abroad and prop up his regime. For decades, Britain has actively courted the Russian billionaires, ignoring reports of their suspicious wealth. Billions of dollars poured in. Today, there's so much Russian cash in London; the capital is nicknamed "Londongrad." Now, with Russia laying waste to Ukraine, Britain is under pressure to show it can stop the flood of corrupt money. Bill Whitaker goes to the heart of Russia's capital abroad – London – to find out. Laurie Anderson – 60 MINUTES' Anderson Cooper profiles artist Laurie Anderson, one of America's most unusual – and visionary – creative pioneers. There is little Anderson hasn't done over a genre-blurring five-decade career as a performance artist, composer, filmmaker, electronics whiz, and, first and foremost, storyteller. She has won a GRAMMY for an album about Hurricane Sandy, served as the first official artist in residence for NASA, and still, today, at 74, remains uncategorizable and busy as ever. 60 MINUTES catches up with Anderson as her largest-ever U.S. exhibition is on display at the Smithsonian's Hirshhorn Museum in Washington, D.C.
