Good morning, and TGIF! Here are some of the stories we're following today:

1. Tensions cool dramatically in St. Louis suburb

After nearly a week of clashes between police and protesters amid racial tensions, Thursday night took a different turn in Ferguson, Missouri, where the atmosphere was more like a block party. That change can be attributed to a new police force — the state Highway Patrol — being put in charge of overseeing safety. Gov. Jay Nixon tasked Highway Patrol Capt. Ron Johnson, who is black and grew up in Ferguson, with leading troopers in the city. He was greeted by cheers and promised the crowd that his officers were “going to march with you.” Still, some protesters are demanding the name of the officer who fatally shot 18-year-old Michael Brown, whose death Saturday became a flashpoint for the unrest. That officer could be identified Friday. Read more in NEWS.

2. Iraq’s al-Maliki agrees to give up post

The political winds are shifting in Iraq, which has seen major cities overrun by Islamic militants who’ve created a flood of refugees looking to escape the deadly violence. In the latest announcement, Nouri al-Maliki, the country’s prime minister for eight years, said late Thursday he will relinquish the post to fellow Dawa Party member Haider al-Abadi. Al-Maliki has been struggling for weeks to stay in power amid opponents accusing him of failing to secure the country and alienating the Sunni minority. Read more in NEWS.

3. Robin Williams was in early stages of Parkinson’s

The late comedian’s wife revealed Thursday that before he took his life, he was suffering from the early stages of Parkinson’s. The stunning admission could have contributed to his state of mind, doctors say, because the disease itself can produce depression. “I think it makes absolute sense that if you have a pre-existing depression and you get a disorder that by itself has a tendency to cause depression and you also just learned you have the disorder, it creates the perfect storm,” one doctor told NBC News. Williams’ body was found Monday in his home in Northern California, and he had been known to be struggling with depression and addiction throughout his life. Read more in HEALTH.
