Josh Kelly suffered from epilepsy, a brain disorder that forced him to drop out of high school nine days before graduation. But Kelly was determined not to miss out on another educational milestone. For nearly a decade, Kelly attended Idaho State University working toward a degree in geology, with his faithful service dog, a black pit bull named Cletus, by his side. The pair would dutifully walk two miles both ways to catch the bus to campus.

Unfortunately, Kelly passed away in February just two classes shy of his degree. Nonetheless, ISU granted him a posthumous degree on May 10. In the young man's place, Kelly's tearful father, Terrell, walked across the stage with Cletus by his side, accepted the diploma, lifted it to the sky and said almost inaudibly, "This is for Josh."

In honor of Kelly's hard work and his service dog, who gained celebrity status among the students, the undergraduate study hall in the geosciences department has been officially named "Cletus' Corner." Watch the video below. --Lauren Hansen

While Monday night's first presidential debate had record-breaking viewership in the U.S., it also caught the attention of vested interests abroad. Russia state-sponsored media reportedly liked what they were seeing, but it was hardly the same scene in Mexico City:

"You want to go to Mexico or some other country? Good luck," Donald Trump told U.S. manufacturing companies during Monday night's presidential debate against Hillary Clinton.

Thousands of miles away, the 200 people packed into Pinche Gringo, a Texas-style barbecue restaurant in Mexico City, broke into cheers and clinked their glasses frothed with beer.

It was just one of Trump's six references to Mexico last night, and a signal to drink for U.S. expats watching in Mexico.

The patio, filled with wooden tables, a bar pouring draft beers, and a kitchen designed to look like an Airstream trailer, was packed with Democrats and Hillary Clinton supporters who would raise their glasses and yell Salud! everytime Trump mentioned "Mexico." Predictably, there weren't any/many Trump fans in the bar — or anywhere else in Mexico, for that matter. [Fusion]

Up to a million American citizens live in Mexico; the event at Pinche Gringo, organized by Democrats Abroad, also helped expats register to vote. "Trump is having a huge effect. His comments have really helped gin up interest," Doug Hall, an American citizen who now lives in Mexico, told Fusion. "There is a lot of momentum this year. We are registering a lot of people."

Mother Earth isn't the only one suffering from rising levels of air pollution. A new report by the World Health Organization out Tuesday revealed that in 2014, 92 percent of the world's population was living with levels of air pollution that exceeded what WHO considers to be safe.

In particular, WHO is concerned about higher concentrations of pollution particles that are smaller than 2.5 micrometers, as these particles are tiny enough to "be inhaled, travel into the lungs, and enter the bloodstream," The Washington Post reported. "People think of air pollution as a respiratory disease," said Carlos Dora, head of WHO's air pollution team. "And in fact, it's heart disease, strokes and cardiovascular. Because there's very small particles that go into the blood. ... The damage air pollution does to the vessels is similar to the damage that cholesterol or high blood pressure do."

In 2012, an estimated 7.3 million people died from air pollution, produced both inside the home and outdoors. The problem is particularly acute in "low- and middle-income countries," which WHO reported accounted for 88 percent of the 3 million premature deaths caused by outdoor air pollution in 2012.

Still, wealthier countries certainly aren't in the clear. In Europe, cities including Paris and London failed to meet air quality standards, and in America, both Los Angeles and Manhattan fell short. Becca Stanek

Senate Democrats blocked the government spending bill 55-45 Tuesday, threatening a government shutdown if an agreement is not reached by Friday's midnight deadline. The GOP resolution, which would have funded the government through Dec. 9, was rejected on the grounds that it did not give aid to Flint, although it did for flood victims in Louisiana, Maryland, and West Virginia. Democrats have said they don't oppose the flood aid but that it should not be included unless aid also goes to Flint for the water crisis.

"Why do you feel you have to punish people in Louisiana ... for Flint when there's a pathway forward on Flint through the WRDA bill?" Sen. Bill Cassidy (R-La.) said, naming a bill the Senate approved to give Flint $220 million for water infrastructure, although it was not included in the House's draft, meaning the two chambers would need to negotiate it after the elections.

Minority Leader Harry Reid (D-Nev.) said, “The Republicans are essentially saying the disasters in our states are more important than the disasters in your state. It is unfair, and it is wrong.” Jeva Lange

The first presidential debate of the 2016 election cycle was the most-watched debate ever, with 80.9 million people tuning in to see Donald Trump and Hillary Clinton go head to head. Clinton and Trump's first presidential showdown topped the second-most viewed debate in U.S. history, between Jimmy Carter and Ronald Reagan in 1980, by 300,000 viewers.

The debate was especially accessible for viewers this year as it was shown on every major news network, in addition to being streamed on Facebook and YouTube. By comparison, the first debate between Mitt Romney and President Obama in 2012 garnered only 67 million viewers on average. And while some analysts had expected viewership to drop after the first hour of the debate, Nielsen data showed early signs of viewers sticking around to watch the whole thing.

The official Nielsen number tallies only traditional TV viewers, disregarding online streaming or group-watching events, so likely many more than 80.9 million people actually watched the debate. Still, Monday's record falls short of some early expectations the debate would attract 100 million or more viewers, which would have been comparable to Super Bowl 50. Jeva Lange

Former New York City Mayor Rudy Giuliani said in a Monday night interview that Hillary Clinton might be "too stupid to be president," if she really believed her husband Bill Clinton over then-White House intern Monica Lewinsky when he denied early allegations of their affair in the 1990s. "She didn't just stand by him, she attacked Monica Lewinksy," Giuliani said. "After being married to Bill Clinton for 20 years, if you didn't know the moment Monica Lewinsky said that Bill Clinton violated her that she was telling the truth, then you're too stupid to be president."

While Donald Trump was too "gentlemanly" and "reserved" to bring up the subject at the presidential debate Monday night, Giuliani suggested he would not have hesitated to mention Bill's past indiscretions. Giuliani also said the fact that Trump didn't broach the topic is evidence he's a feminist.

Monday night's presidential debate at Hofstra University in New York began at 5 a.m. Tuesday in Moscow, but that didn't deter journalists of the country's state-owned media from rising bright and early to cover the event. They didn't exactly take an unbiased stance, either: "At the very least, [the coverage] shows exactly how smoothly Donald Trump's policy positions dovetail with Moscow's," Julia Ioffe wrote at Foreign Policy.

One such example was when Trump claimed the U.S. shouldn't be the "world's policeman," a stance that Russian President Vladimir Putin has strongly backed. The quote was promptly shared by Russian newspaper Izvestia:

Ioffe runs through other examples of where Trump sounds eerily similar to the Kremlin's messaging, such as in his assertion that Americans created the conditions for the rise of the Islamic State or his denial that there is any evidence to suggest Russia hacked the DNC. See more examples of the overlap at Foreign Policy, here. Jeva Lange

Hillary Clinton wasn't particularly impressed with Donald Trump's debate performance Monday night, and she suggested Tuesday that Trump's complaints about his microphone indicate he wasn't either. Earlier Tuesday, Trump wondered whether his debate microphone was purposely tampered with, because he said his volume seemed lower than Clinton's and his microphone seemed to be capturing a sound some thought sounded like the sniffles. "Anyone who complains about the microphone is not having a good night," Clinton said, in response to a question about their microphones during a brief presser aboard her plane.

Clinton thought Trump's biggest stumbles of the night were his "charges and claims that were demonstrably untrue" and the opinions he offered that "a lot of people would find offensive and off-putting." "I'm excited about where we are in this country," Clinton said. "He talks down America every chance he gets. He calls us names. He calls us a third-world country."

Clinton and Trump will face off again Sunday, Oct. 9, in a presidential debate hosted by Washington University in St. Louis and moderated by ABC's Martha Raddatz and CNN's Anderson Cooper. Becca Stanek
