Will It Be Sunny in Philadelphia?

After a turbulent Republican convention, Democrats are hoping to show a more unified front. Bernie Sanders isn’t going to pull a Ted Cruz, as he’s calling for unity to defeat Donald Trump. How his supporters react is another question, especially after WikiLeaks released hacked emails suggesting the party plotted to undermine Sanders during the primary. The revelation already has triggered the resignation of DNC Chairwoman Debbie Wasserman Schultz.

Hillary Clinton’s Left Turn

Lots of Sanders supporters weren’t happy with Clinton’s pick of Tim Kaine as a running mate, rather than a more progressive standard-bearer like Elizabeth Warren. Based on Clinton’s positions this campaign season, though, some view her as one of the party’s most liberal nominees in recent history. “Two years ago, it was almost unimaginable that Hillary Clinton would be campaigning on debt-free college, expanding Social Security, breaking up ‘too big to fail’ banks and all these other progressive issues,” says one observer. Here’s how that could play into voters’ frustration with the status quo.

Why U.S. Hospitals Weren’t Warned About Scopes

In early 2013, after superbug outbreaks in France and the Netherlands, Olympus Corp. alerted its European customers that a medical scope it manufactured could become contaminated. As the company investigated a similar outbreak in Pittsburgh, a top executive in the U.S. emailed its Tokyo headquarters asking if the same information should be sent out in America. The answer was no. Since 2013, at least 35 people at U.S. hospitals have died after infections from contaminated Olympus scopes, according to hospitals and public health officials. Here’s more from The Times’ investigation.

Zika and the Life of a Single Mom

In Brazil, as many as one-third of mothers are unmarried – and the rate is even higher in its poorest areas. Those regions are also the hardest hit by Zika. Now, as babies are born with disabilities linked to the virus, women increasingly face the strain not only of raising a baby alone but also of caring for a child that may require near-constant attention. Sometimes, even if there is a father in the picture, he may drift away.

Occupy Oaxaca

Since May, teachers have been living in a tent city on the central plaza of Oaxaca and blocking roads to protest education reforms by Mexico’s federal government. Last month, eight people died and more than 100 were injured in a clash with police. For many students, though, the standoff means they’ve lost up to six weeks of school. For others, it means a damper on an annual celebration of indigenous and mestizo heritage that usually draws lots of tourists to the city starting today -- but not so many this year.

The Bitter, and the Sweet Science

Zenon Balderas says he pushed his son Carlos hard for a reason – to keep him out of the strawberry fields and the gangs in California. “Was I too tough?” he wonders. “Sometimes I feel bad.” Now Carlos is heading to the Olympic Games in Rio de Janeiro with the U.S. boxing team.
