Low-grade methane leaks are bad for business (that gas could be heating up a home) and bad for the environment (it traps heat up in the atmosphere). Because a methane spill is invisible and has no smell — unless there's about to be an explosion (and if so, run!) — it can be hard to track one down.

That's where a tricked-out Google Street View car comes into play. Google Earth Outreach and the Environmental Defense Fund have teamed up to turn several Subaru Imprezas into mobile methane trackers. As Bloomberg reports, scientists add tubing across the front grill, which helps push a constant stream through a very small dehumidifier and then into a gas analyzer. Real-time data is streamed to a monitor, showing how fast the car is driving and the amount of methane on the street.

The pilot project's results were released on Wednesday, with information coming in from Boston, Indianapolis, and Staten Island. The findings seem to show that older cities have more of an issue with leaks, likely due to old infrastructures. Indianapolis, which has newer pipes, was the cleanest, with just one leak recorded for every 200 miles.

Those involved in the project are excited to use the information as a way of influencing how cities plan in the future. "This is the beginning of what I really see as a big shift in the way we can give people data about the environments they live in," Steven Hamburg, chief scientist for the EDF, told Bloomberg.

The United States will not recognize the results of Venezuela's presidential election, U.S. Deputy Secretary of State John Sullivan announced Sunday.

Venezuelan President Nicolas Maduro is expected to secure another six-year term as his country goes to the polls despite the dire conditions Venezuelans face under his leadership. Venezuela has been in a state of crisis for several years, suffering grave shortages of food, medicine, and other necessities as well as hyperinflation.

Some of Maduro's critics are boycotting the election, which they say will be rigged regardless of participation, in an attempt to delegitimize Maduro's win. The two most popular opposition candidates have been banned from running by the Maduro government.

Sullivan indicated the U.S. is also considering oil sanctions on Venezuela and will broach the topic at Monday's G20 meeting in Buenos Aires. "We need to make sure we adhere to our goal which is to target corrupt regime officials and not the people of Venezuela," he said. "We don't want to damage the country in a way that makes it difficult to repair after democracy is restored." Bonnie Kristian

A North Korean military officer and a civilian defected from their country early Saturday morning. They were found in the Yellow Sea, the ocean area between the Korean Peninsula and mainland China, close to the border between North and South Korea. The two North Koreans reportedly expressed a desire to defect and were taken to South Korea.

This is the first military defection from North Korea in a decade, and it comes shortly before the planned talks between President Trump and North Korean leader Kim Jong Un. Bonnie Kristian

In August of 2016, President Trump's eldest son, Donald Trump Jr., met in Trump Tower with an emissary of two Saudi princes offering his father help in winning the presidential election, The New York Times reported Saturday.

Per the Times report, the meeting was arranged by Erik Prince, founder of the private military firm formerly known as Blackwater and brother of Education Secretary Betsy DeVos. Also present was an Israeli social media specialist who wanted to work for the campaign.

Trump Jr. said through a representative the meeting happened, but he rejected the offers. The Times story says otherwise, citing unnamed sources to report "Trump Jr. responded approvingly," and the emissary, George Nader, "was quickly embraced as a close ally by Trump campaign advisers — meeting frequently with Jared Kushner, Mr. Trump's son-in-law, and Michael T. Flynn, who became the president's first national security adviser." The social media specialist, Joel Zamel, was later paid a "large sum of money" by Nader, though the reason for the payment is disputed.

This rendezvous took place two months after Trump Jr.'s meeting with a Russian lawyer with ties to the Kremlin who offered opposition research on Hillary Clinton. Bonnie Kristian

Saturday Night Live veteran Tina Fey closed out the show's 43rd season hosting a star-studded episode. Her 30 Rock costar, Alec Baldwin, returned once again as President Trump, and Robert DeNiro and Ben Stiller reprised their recent appearances as Special Counsel Robert Mueller and Trump attorney Michael Cohen, respectively.

But not every cameo happened in character: Jerry Seinfeld, Fred Armisen, Donald Glover, Anne Hathaway, Tracy Jordan, Benedict Cumberbatch, Chris Rock, and more showed up for a meta bit about whether the show is disadvantaging newer cast members by bringing in so many celebrities for choice roles.

After extensive trade negotiations, Washington and Beijing said in a joint statement Saturday China will buy more American exports.

"To meet the growing consumption needs of the Chinese people and the need for high-quality economic development, China will significantly increase purchases of United States goods and services," the statement said. "This will help support growth and employment in the United States. Both sides agreed on meaningful increases in United States agriculture and energy exports."

The statement did not specify the quantity or timeline of the increase, nor did it say whether China would be exempted from President Trump's steel and aluminum tariffs. Rather, the "United States will send a team to China to work out the details." Bonnie Kristian

President Trump tweeted Saturday evening in apparent response to Friday's news that an American academic working as an FBI informant met with several members of his 2016 campaign as part of the agency's then-beginning probe into Russian election meddling.

Friday's New York Times report about the informant said there is no evidence "the informant acted improperly" or that the inquiry was "politically motivated." Rep. Devin Nunes (R-Calif.), chair of the House Intelligence Committee, has already subpoenaed the Justice Department for documents pertaining to the informant, and House Freedom Caucus leader Rep. Jim Jordan (R-Ohio) said Friday the FBI's actions, if reports are correct, are "as wrong as it gets." Bonnie Kristian

The 10 people killed in Friday's mass shooting at Santa Fe High School near Houston, Texas, were identified by Galveston County authorities Saturday: Sabika Sheikh, Ann Perkins, Angelique Ramirez, Shana Fisher, Kim Vaughan, Chris Stone, Cynthia Tisdale, Christian "Riley" Garcia, Jared Conard Black, and Kyle McLeod.

Perkins and Tisdale were substitute teachers; the other eight victims were Santa Fe students. Houston Texans player J.J. Watt has announced he will cover the cost of all 10 funerals.

Sheikh was an exchange student from Pakistan, and Secretary of State Mike Pompeo on Saturday sent his "deepest condolences" to her loved ones. "I don't blame the murder of my girl on American society but on that terrorism mindset that is there in all societies. We need to fight it all over the world," said her uncle, Ansar Sheikh. "I do ask the American government to make sure weapons will not be easily available in your country to anybody. Please make sure this doesn't happen again. It really hurts."

The suspect, Dimitrios Pagourtzis, has been arrested on multiple murder charges. He has given a statement "admitting to shooting multiple people" and reportedly told police he "did not shoot students he did like so he could have his story told." Bonnie Kristian
