(CNN) -- Earlier this month, an AeroMexico plane made an important flight from Mexico City to Madrid. The flight wasn't notable for who was inside the cabin, but for what was inside the fuel tank: it was the world's first transatlantic commercial flight using biofuel. The engines on that flight were powered by a fuel mixture that was 30% biofuel from the jatropha plant, and the trip followed a pair of Mexican domestic commercial flights by Interjet that used the same formula. Mexico is known for its oil production, but it could be its less obvious flats of arid and marginal land that will be the future of Mexico's energy resources. The country has quietly positioned itself to become a potential leader in biofuel production as scientists develop a second generation of fuels derived from sources that don't compete for arable land or with food. Jatropha-based biofuels are being increasingly used in Mexico, and agave -- the plant from which tequila is made -- is being studied as a new source for ethanol. But some observers warn that Mexico's cumbersome land laws make it too hard to purchase the land needed for cultivation at competitive prices. Some biofuels, such as ethanol derived from corn and sugar, can indirectly raise the prices of staple foods in many places, along with raising ethical issues, said Gilberto Lopez Meyer, director of Airports and Auxiliary Services (ASA), the Mexican government agency that oversaw the biofuel flights. So in 2007, Mexico, along with 14 other member countries of the International Civil Aviation Organization, committed to developing new strategies for second-generation biofuels that would not affect food production. "We returned to Mexico with a mission," Lopez told CNN. Lopez's agency teamed up with the state of Chiapas, where Gov. Juan Sabines had already made a name for himself pushing his state toward alternative fuels. Chiapas began cultivating jatropha, whose seeds contain oil that can be extracted and converted into biofuel. The state already uses a jatropha biofuel mix on its buses and trucks, and President Felipe Calderon was on hand in November of last year to inaugurate a biodiesal plant there. ASA partnered with American company UOP, which refined the Chiapas jatropha into jet fuel. When the standards for biofuel use in commercial flights was approved July 1, Mexico was ready to make the domestic Interjet and international AeroMexico flights a possibility. The goal of ASA, which provides almost 100% of the jet fuel in Mexico, is to commercialize and distribute biofuels, Lopez said. "We've been working on this project as part of a global effort to combat climate change," he said. By 2015, the goal is to have 1% of all jet fuel in Mexico be biofuel, and by 2020, 15%, he said. "This is a huge goal," Lopez said. "One percent doesn't sound like a lot, but it equals more than 40 million liters (10.6 million gallons)." Mexico has several things in its favor to become a leader in biofuels, he said. It has plenty of land not being used for food, it has a high demand for energy, and it is located next door to the energy-hungry United States. "Mexico has made the very important first step to be in a very priviledged place," Lopez said. Halfway across the world, researchers at Oxford recently published a study extolling the benefits that ethanol derived from agave. Agave can grow in arid land, and produces less than half of the carbon dioxide emissions produced by corn-based ethanol, Oliver Inderwildi, one of the study's authors, told CNN. Sugar-based ethanol produces even less emissions, but it needs arable land for cultivation. "We need every space we can get, every arable land, for food," Inderwildi said. "We think agave may be one part of the solution." For their study, the researchers did a life-cycle analysis for the production of ethanol based on a hypothetical plant in Jalisco, Mexico, where 90% of tequila is produced. Potentially, agave plantations could boost local economies and create jobs, Inderwildi said. Mexico, the native home of agave plants, stands to benefit if such an ethanol industry takes off. Food prices would be spared, but would drinkers have to pay more for their margaritas and tequila shots? The tequila business is very small compared to the fuel business, and is also more expensive than fuel ethanol, so Inderwildi predicts that alcohol prices would remain stable. And unlike tequila, which requires the harvesting of the agave stem only, ethanol production would also require harvesting the leaves of the plant. "Our study backs up that this is a good idea from an environmental perspective," he said. The catch, for now, is that neither jatropha or agave biofuel production is cost-effective. But technological advances and oil prices make such alternatives more desirable. When that tipping point comes, Mexico will be ready, the experts said. But James Row, CEO of Houston-based Producers Energy and part owner of a Mexican-based biodiesel company, told CNN that Mexico is still far from being an ideal place to produce biofuels. "Mexico is absolutely a perfect country for biodiesel, especially if it can be domestically grown," he said, but the country's ejido system -- collectively-held land in rural areas -- creates hurdles for private investment. The result is difficulty in finding continuous large areas of rural land that can be negotiated for use for cultivation, or high prices that make it cost prohibitive. Without land reform, issues with land availability will continue, and Mexico will fall a decade or more behind other countries in the biofuels sector, Row said. The demand is there, the land is there, but there is no way to get it, he said. "Now is the time for Mexico to get its act together for biofuels," he said.

If Mitt Romney were to write a bumper sticker slogan for the past month, it would probably be, "Detroit DID go bankrupt. Russia IS a geopolitical foe." Reality isn't quite so simple as to perfectly apply recent developments on Detroit and Russia to the American debate in 2012, but neither were Romney's arguments on the car industry and on Russia. That didn't stop Democrats and pundits from using them to beat Romney down. And it would be a good retort to Joe Biden's often-repeated 2012 bumper sticker slogan: "Osama bin Laden is dead and General Motors is alive!" Biden used the phrase to simultaneously flaunt what the Obama administration accomplished in the war on terror and hit Romney for his position against the auto bailout. Romney had different ideas than the president about the war on terror, and he also had outspoken ideas on Russia, which he told Wolf Blitzer on CNN in March of 2012 was "without question our number one geopolitical foe." His statement drew snickers in Washington and complaints in foreign policy circles that he was stuck in the Cold War. Archives: Hillary Clinton criticizes Romney's remarks on Russia . "You don't call Russia our No. 1 enemy -- not al Qaeda, Russia -- unless you're still stuck in a Cold War mind warp," President Barack Obama said at the Democratic National Convention last September. The president probably still wouldn't call Russia this country's top foe. But now that Russia has given NSA leaker Edward Snowden a year of asylum, and the two countries can't find accord on Syria or Iran, he might choose not to put the line in his convention speech. Snowden asylum could cancel planned Obama-Putin talks . "Now is the time to fundamentally rethink our relationship with Putin's Russia," Sen. John McCain said upon hearing news of Snowden's asylum. "We need to deal with the Russia that is, not the Russia we might wish for. We cannot allow today's action by [Russian President Vladimir Putin] to stand without serious repercussions." "Russia has stabbed us in the back," said Sen. Chuck Schumer, the New York Democrat. He called on Obama to protest by demanding the upcoming G-20 summit for world economic powers be moved away from Russia. Biden's slogan, "General Motors is alive!" drew a direct contrast between the candidates on the auto bailout that Obama engineered after initial action by President George W. Bush. Romney's much-cited New York Times op-ed argued the car industry should be shepherded into a managed bankruptcy and not propped up with taxpayer dollars. The headline of Romney's op-ed in November 2008 was "Let Detroit Go Bankrupt." That headline followed him all the way to November of 2012 when he lost the election. Romney's argument in the opinion piece was directed at the car industry, but it foreshadowed last month's news that the Detroit the city, once the powerhouse of the American economy, was going bankrupt. "[W]e refused to throw in the towel and do nothing," Obama said in a video message in October of 2012. "We refused to let Detroit go bankrupt, I bet on American workers, and American ingenuity and three years later that bet is paying off in a big way." A conservative might apply the high labor costs Romney cited as part of the downfall for the auto industry to the cost of government worker pension plans that have helped put the city in trouble. How to deal with promises made to public employees is an issue Americans will face in the coming decades in places far flung from the Motor City. Hatch: After Detroit, replace public pensions . The federal government has made pretty clear there won't be any sort of bailout for the city of Detroit like there was for the auto industry that lives there. CNNMoney: Why Obama won't bail out Detroit . Campaigns are full of little moments like the Detroit and Russia storylines that may have worked against Romney. They add up. More damaging for Romney than either the Detroit op-ed or the Russia as a foe storyline was his statement to fundraisers about giving up on the 47% of Americans who would not vote for him no matter what. This week we also got the most in-depth explanation from Romney on those comments in the form of a book excerpt from Washington Post writer Dan Balz. Romney said he was misunderstood. More: Romney regrets 47% comments . Archives: Romney doesn't back away from message caught on secret tape . In politics, eight months is an eternity. It's enough time for the Romneys to welcome four new grandchildren into the world. How Detroit and Russia and the 47% factored into 2012 are interesting historical questions, but the national dialogue has moved on. Romney is retired from national politics and the pundits and press have moved on to the 2016 parlor game. Trio of potential 2016 GOP contenders heading to South Carolina .

(CNN) -- Ryan Alexander Jenkins, a reality TV contestant suspected in his wife's slaying, was found hanging from a coat rack in a motel room in an apparent suicide, according to Canadian officials. Police were hunting for Ryan Alexander Jenkins after the death of Jasmine Fiore. Staff at a motel in Hope, British Columbia, found Jenkins dead, officials said. "It was a man hanging by a belt from a coat rack," Kevin Walker, the manager of the budget Thunderbird Motel, told CNN affiliate CTV on Sunday. Walker said a woman, about 20 to 25 years old, dropped off Jenkins at the motel on Friday in a silver Chrysler PT Cruiser with Alberta tags. Police have not been able to identify the woman.  Watch how suspect found in hotel » . Earlier Sunday, Canadian authorities said they had credible information that Jenkins was in Canada and called on him to turn himself in. He was believed to be armed and dangerous.  Watch what led police to hotel room » . The nude body of Jenkins' wife, former swimsuit model Jasmine Fiore, was found last weekend in Orange County, California. CNN has not confirmed reports that the marriage was annulled. Fiore's body was found last Saturday in a Dumpster behind an apartment complex in Buena Park, just outside Anaheim, California. Her teeth had been extracted and fingers removed in what police said was an apparent attempt to conceal her identity. Law enforcement sources have told CNN that Fiore was identified through the serial numbers on her breast implants. Fiore lived in Los Angeles and was last seen alive in San Diego at a poker game with Jenkins, the night before the body was found. Jenkins reported Fiore missing last Saturday night to the Los Angeles County Sheriff's Department, authorities said. The body was identified Monday as Fiore. While the cause of death had not been confirmed, a preliminary coroner's report indicated she was strangled. According to court records in Las Vegas, Nevada, Jenkins was charged in June with battery for allegedly striking Fiore in the arm with his fist. And in 2007, Jenkins pleaded guilty in Calgary, Alberta, Canada to assault in a separate case. He was sentenced to 15 months probation, ordered to undergo counseling for domestic violence and sex addiction and to stay away from the person involved, according to court records. Jenkins, who appeared on the VH1 show "Megan Wants a Millionaire," is from Calgary. 51Minds, which produced "Megan Wants a Millionaire," said Thursday in a written statement that it "was not aware of Ryan Jenkins' record when it cast him. "The company did have in place what it thought was a thorough vetting process that involved complete background checks by an outside company for all contestants on its shows," it said. "Clearly, the process did not work properly in this case. 51 Minds is investigating what went wrong and taking steps to ensure that this sort of lapse never occurs again." CNN's Paul Vercammen contributed to this report.
