Hundreds gathered in Flint, Mich., Tuesday, to celebrate the return home of Olympian Claressa Shields. At 17, Shields became the first U.S. woman ever — and the only American this summer — to win a gold medal in boxing.

In a rare moment of joy, Flint greeted the high school student with a marching band and a motorcycle escort.

After a tsunami disabled the Fukushima Dai-ichi plant in March of 2011, residents of the nearby city of Minamisoma, just 14 miles from the plant, were evacuated.

But within a few months, most returned to their homes. Still, many communities near the plant have remained skeptical and concerned about possible radiation exposure.

To find out how much radiation exposure these people have received, Japanese researchers measured levels of radioactive cesium in nearly 10,000 residents starting six months after the incident.

The Muslim holy month of Ramadan has fallen on the longest and hottest days of the year, which means up to 15 hours of fasting in soaring temperatures.

This seems to have increased the number of Muslims who aren't fully observing the fast, and may be sneaking a bite or a drink — though no one wants to say so on the record.

Mitt Romney's new running mate has authored some provocative policy proposals to cut budget deficits and overhaul Social Security, Medicare and Medicaid. But Rep. Paul Ryan has also been an advocate for a different course for the central banking system of the United States, the Federal Reserve.

For the past 35 years, the Fed has had a dual mandate from Congress: to set interest rates at levels that will both foster maximum employment and keep prices stable. Put another way, the Fed's goals are to get unemployment as low as possible while keeping inflation in check.

Britain's fifth-largest bank has agreed to pay $340 million to settle charges by New York regulators that it laundered money for Iranian clients.

NPR's Chris Arnold filed this report for our Newscast unit:

"In court documents, the regulator alleged that for 10 years Standard Chartered Bank quote 'schemed with the Government of Iran and hid from regulators roughly 60,000 secret transactions... involving $250 billion dollars and reaping hundreds of millions of dollars in fees for the bank.'

As part of the NPR Cities Project, we're exploring some "gee-whiz" questions about how cities work. Melissa Block talks to Gideon Berger, Fellowship Director for the Urban Land Institute, on the street in Washington, D.C.'s Chinatown. They talk about the trickiness of timing traffic lights

The British bank accused of using its New York branch to launder money from international transaction has agreed to pay New York's top banking regulator $340 million. Regulators said the bank schemed to hide more than 60,000 financial transactions totaling $250 billion for Iranian clients. The bank denied the charges. Audie Cornish talks with Jim Zarroli.

In light of this summer's record high temperatures, we find perspective on really hot temperatures. In an experiment, scientists at Europe's CERN laboratory claim to have achieved the highest temperature ever produced by humans — about 5.5 trillion degrees. Audie Cornish and Melissa Block have more.
