Martyn Poliakoff, chemistry professor at the University of Nottingham and owner of the best head of hair in science, has a video today exploring the properties of aluminum (or as chemists call it, "aluminium"). There are a lot of fascinating facts in here, but most interesting is a special periodic chart showing all the elements like usual, but with the size of each box adjusted to reflect their relative abundance. Apparently, there is more aluminum than iron on this planet!

During Monday's debate, Donald Trump defended his decision to not pay some contractors who worked for him on different projects.

Hillary Clinton told Trump she has met with dishwashers, painters, glass and marble installers, and other contractors who were "stiffed by you and your businesses." An architect that Clinton said designed the clubhouse for one of Trump's golf courses was in the audience at Hofstra University, and although the man built a "beautiful facility that was immediately put to use," Trump wouldn't pay him.

"Maybe he didn't do a good job and I was unsatisfied with his work," Trump interjected. Clinton said the workers deserved "some kind of apology from someone who has taken their labor, taken the goods they produced, then refused to pay them," adding that she was "relieved" her late father never did business with Trump. Trump responded by saying he does pay contractors and his "obligation right now is to do well for myself my family my employees for my companies and that's what I do." Trump added that he has plenty of workers who are "unbelievably happy and love me," then used the remainder of his time to plug his new hotel near the White House. "If I don't get there one way," he vowed, "I'll get to Pennsylvania Avenue another." Catherine Garcia

At Monday's debate at Hofstra University, Donald Trump blamed Hillary Clinton for her husband's signing of NAFTA, saying she has ruined the economy over the past 30 years, when she was a first lady, senator, and secretary of state, and he also said she has been fighting the Islamic State "for your entire adult life." Clinton at one point quipped, "I have a feeling that by the end of the evening, I will be blamed for everything that's ever happened." Trump jumped in: "Why not?" "Why not, yeah, why not?" Clinton responded, laughing. "Just join the debate by saying more crazy things." Peter Weber

Hillary Clinton and Donald Trump got into their first heated exchange of the presidential debate in a fiery clash over the North American Free Trade Agreement. "You approved NAFTA," Trump interrupted Clinton, "which is the single worst trade deal ever approved."

Trump continued to charge Clinton and her husband, former President Bill Clinton, over NAFTA, to which Clinton snapped, "Donald, I know you live in your own reality, but that is not the facts."

Hillary Clinton didn't wait too long during Monday night's debate to use earlier comments made by Donald Trump during the Great Recession against him.

Trump, she said, was one of the "people who rooted for the housing crisis." In 2006, Clinton continued, Trump said, "'Gee, I hope it does collapse, because then I can go in and buy some and make some money.' Well, it did collapse." She was interrupted by Trump, who embraced his remarks, saying, "That's called business, by the way." Clinton finished her statement by reminding the audience that "nine million people lost their jobs, five million lost their homes, and $13 trillion in family wealth was wiped out" during the Great Recession.

From the beginning of Monday's presidential debate, Hillary Clinton has referred to her Republican rival, Donald Trump, as "Donald." Trump, at least in the first few minutes, made a show of referring to Clinton as "Secretary Clinton." In a response about NAFTA, Trump said "Secretary Clinton — yes, is that okay? I want you to be very happy. It's very important to me."

Later, he called her "Hillary." Peter Weber

Hillary Clinton wants to get a rise out of Donald Trump at the presidential debate, and she plans to do so ... by calling him by his name. "Mrs. Clinton is eager to play offense and try to get under [Trump's] skin, by doing things like calling him 'Donald' and questioning his net worth," The New York Times reported last week.

And calling him Donald she certainly is. "How are ya, Donald?" Clinton asked her opponent as soon as they walked out on stage.

Trump, for his part, is apparently calling Clinton "Secretary Clinton" — for now. Jeva Lange

It's been 10 years since the final episode of Will & Grace aired, but everyone's favorite BFFs have reunited — and they're with her.

In a nearly 10-minute video released Monday, Eric McCormack, Debra Messing, Megan Mullally, and Sean Hayes reprised their roles as the 2016 versions of Will, Grace, Karen, and Jack. Will and Grace, unsurprisingly, are Hillary Clinton supporters (as is Messing in real life), while Karen is firmly ensconced aboard the Trump Train, even having sent her maid Rosario to Trump University (where she studied dusting). Jack, meanwhile, is an angry, unemployed white man who happens to be registered to vote in Pennsylvania, making him the one to court this election.

After running through the many reasons why he should vote for Clinton, Grace finally convinced him by dangling a pop star supporter in front of his face (and no, it's not Cher). It's the same Will & Grace as before, with off color jokes (and some NSFW language), but the underlying message is serious: Get out and vote. Watch the reunion below. Catherine Garcia
