Q: Paragraph: Grown in-vitro from cattle stem cells at a cost of 250,000 euros ($332,000), the burger was cooked and eaten in front of television cameras to gain the greatest media coverage for the culmination of a five-year science experiment. Resembling a standard circular-shaped red meat patty, it was created by knitting together 20,000 strands of laboratory-grown protein, combined with other ingredients normally used in burgers, such as salt, breadcrumbs and egg powder. Red beet juice and saffron were added to give it colour. The two food tasters were reserved in their judgement, perhaps keen not to offend their host at the London event, noting the burger's "absence of fat". Pressed for a more detailed description of the flavour, food writer Josh Schonwald said the cultured beef had an "animal protein cake" like quality to it, adding that he would like to try it with some of the extras often served with traditional burgers - salt, pepper, ketchup and jalepenos. Even the scientist behind the burger's creation, vascular biologist Mark Post of Maastricht University in the Netherlands, was relatively muted in his praise of its flavour. "It's a very good start," he told the hundreds of reporters who had gathered to watch the meat being cooked and served. The Dutch scientist's aim was to show the world that in the future meat will not necessarily have to come from the environmentally and economically costly rearing and slaughtering of millions of animals. "Current meat production is at its maximum - we need to come up with an alternative," he said. The World Health Organization (WHO) says meat production is projected to rise to 376 million tonnes by 2030 from 218 million tonnes annually in 1997-1999, and demand from a growing world population is expected to rise beyond that. According to a 2006 report by the U.N. Food and Agriculture Organization (FAO), industrialised agriculture contributes on a "massive scale" to climate change, air pollution, land degradation, energy use, deforestation and biodiversity decline. The meat industry contributes about 18 percent of global greenhouse gas emissions, a proportion expected to grow as consumers in fast-developing countries such as China and India eat more meat, the report said. Chris Mason, a professor of regenerative medicine at University College London, who was not involved in the research, said it was "great pioneering science" with the potential to ease environmental, health and animal welfare problems. But, he added: "whilst the science looks achievable, the scalable manufacturing will require new game-changing innovation". Post said he was confident his concept can be scaled up to offer a viable alternative to animal meat production, but said it may be another 20 years before lab-grown meat appears on supermarket shelves. He also conceded that the flavour of his meat must be improved if it is to become a popular choice. Post resisted requests from journalists from all over the world eager to try a morsel of the world's first cultured beef burger, saying there was not enough to go around. Instead, he said, his children would be offered the leftovers. ($1 = 0.7528 euros) Claim: First taste of test-tube burger declared 'close to meat'.

A: The world's first laboratory-grown beef burger was flipped out of a petri dish and into a frying pan on Monday, with food tasters declaring it tasted "close to meat".

Q: Paragraph: "Campaigning for president in the liberal oasis of Madison, U.S. Sen. Bernie Sanders of Vermont rose to the defense of marijuana. Critical of the nation's war on drugs, Sanders said the lives of millions of Americans have been ""ruined"" because they got a police record for possessing marijuana. ""Today, under the federal Controlled Substance Act, marijuana is listed in the same Schedule I as heroin. That is nuts,"" Sanders declared March 26, 2016, 10 days before he defeated Hillary Clinton in Wisconsin's Democratic primary. ""Now people can argue -- although I suspect in this audience there may not be much of an argument -- about the pluses and minuses of marijuana,"" he said, drawing cheers from some of the thousands in attendance at the Alliant Energy Center. ""But everybody knows marijuana is not a killer drug like heroin."" Sanders then noted he had introduced legislation to remove marijuana from the Controlled Substance Act because possession of it ""should not be a federal crime."" We found that Sanders wasn't smoking anything funny in claiming that both marijuana and heroin are Schedule I drugs, which he has continued to say while campaigning in New York and Pennsylvania. But his claim is somewhat misleading: That classification is based on a drug's acceptable medical use and the drug's abuse or dependency potential, not on criminal statutes. The law The Controlled Substance Act, adopted in 1970, uses five schedules to classify drugs and narcotics by medical use and potential to incite substance abuse. On the low end is Schedule V, which includes substances such as cough medicines with small amounts of the narcotic codeine. At the high end is Schedule I, which lists the ""most dangerous"" drugs -- those that have ""no currently accepted medical use and a high potential for abuse."" Marijuana is stronger than when the Controlled Substance Act was adopted (as ex-GOP presidential candidate Carly Fiorina correctly stated). Nevertheless Schedule II includes some drugs often considered more dangerous than marijuana. Here's a look at some of the drugs in the two schedules: Schedule I Schedule II Marijuana Cocaine Heroin Methamphetamine LSD Methadone Ecstasy OxyContin Peyote Fentanyl The Huffington Post in April 2016, citing figures from the federal Centers for Disease Control and Prevention, said the nation recorded no marijuana overdose deaths in 2015. Likewise, there were zero in 2014. It's possible marijuana might soon be moved off of Schedule I. A week after Sanders' speech, the Washington Post reported that the U.S. Drug Enforcement Administration said it hopes to decide by July 2016 whether to change the federal status of marijuana. Now let's get to Sanders' implication that the schedule relates to criminal law enforcement. Marijuana treated differently Distribution, manufacturing or possession of a Schedule I substance is indeed a federal offense. Additionally, marijuana being on Schedule I, drug policy experts told us, makes it more difficult for licensed dealers in states that have legalized marijuana or medical marijuana to get bank accounts and to deduct business expenses on their taxes. And the classification makes it more difficult for researchers to study marijuana in clinical trials. But judges come down harder on heroin possession than marijuana possession. And when it comes to enforcement of criminal statutes, the federal government to some extent has looked the other way when it comes to marijuana. As PolitiFact National stated in a related fact check: Schedule I substances cannot legally be used for medical purposes, however, 20 states and the District of Columbia have passed laws legalizing medical marijuana. In 2009, the administration of President Barack Obama, a Democrat, told federal law enforcement agencies to stop targeting medical marijuana dispensaries, signaling a change from the approach of Obama's predecessor, Republican President George W. Bush. Similarly, in 2013, the Department of Justice said it would not target new laws in Colorado and Washington legalizing recreational marijuana. While Sanders equates the handling or marijuana and heroin, it's difficult to imagine the federal government not enforcing the law if states started legalizing heroin. Our rating Criticizing the nation's war on drugs, Sanders says that under the federal Controlled Substance Act, ""marijuana is listed in the same Schedule I as heroin,"" even though ""marijuana is not a killer drug like heroin."" Like heroin, marijuana is indeed listed as a Schedule I drug, the federal designation given to drugs considered the most dangerous. But at least under the Obama administration, the federal government doesn't treat it as one under the law. For a statement that is accurate but needs clarification, our rating is . Claim: "Under the federal Controlled Substance Act, marijuana is listed in the same Schedule I as heroin,"" even though ""marijuana is not a killer drug like heroin."

Q: Paragraph: The FireWagon is equipped with Drier's tools of the trade: a delicate torch, a small cylinder of propane and a stock of borosilicate glass that can tolerate heat and is chemically inert. Drier frequently takes the portable lab-on-wheels around the city to demonstrate his passion: scientific glassblowing. But his real home base is his expansive shop in the lower level of the UW-Madison chemistry building, the Wisconsin State Journal reported. Here, wearing special dark glasses and using a glassblowing technique called flame-working or lamp-working, Drier makes customized, highly specialized glassware used in cutting-edge research across campus: from chemistry to the departments of medical physics, geology, medicine, food science, molecular and civil engineering, material science, medical engineering, and more. "Definitely a lot of people," request glassware, he said. "And a lot of work." Drier's craft is also showcased at the Madison Children's Museum, where his Rube Goldberg-esque maze of scientific glassware hangs in a window called the "Sidewalk Surprise." The piece can be viewed inside the museum's free community concourse area and also from the street, and will be on display through summer. Drier built the glass bubble columns that are a permanent feature in the "Wayback" area of the museum's second floor, as well. When he brings his FireWagon to the children's museum, "the kids just love to watch because it's mesmerizing," said museum exhibit designer and developer Nadia Niggli. "It almost feels like magic." "It's such a specialized art," she said. "He's got this interesting crossover between art and science. And here (with his 'Sidewalk Surprise'), he's using these serious, very functional pieces in a new, more playful way. It has a little of the 'mad scientist' feel to it." Drier, for one, can't believe his luck. As a scientific glassblower, he's not just shaping glass, but inventing new processes. "How awesome is that," he said, as he lit a gas blower and aimed a flame at a glass tube while doing an interview in his shop. "That's why this job is so fantastic. This is a great job, and every day I give thanks." Associate Professor of Chemistry Zach Wickens, who came to UW-Madison last fall, was partly lured here because the university has its own resident glassblower. Harvard University, where Wickens previously was a postdoctoral research scholar, does not. "It's been amazing" to have a scientific glassblower on campus, said Wickens. Along with making a broad range of glassware for chemistry labs across the department, Drier "has been helping me get into a new area of chemistry that there isn't commercial glassware for, where we're using electricity to help run chemical reactions. And this lets us reduce chemical waste really dramatically. "I'm actually working with Tracy to design new glassware that we can use to quickly test these ideas," Wickens said. "With this glassware, we're going to be able to ask questions we couldn't otherwise ask, and develop reactions we otherwise couldn't develop. So it's pretty profound. I don't know what I would be doing without him." Drier first got into glass as a kid, when his father brought home a how-to book from the library. It kindled an avid hobby for Drier, his father and his brother Tim. Tim dove into scientific glassblowing right out of high school, enrolling at Salem Community College in Alloway, New Jersey the only college in the country offering a two-year degree in scientific glassblowing and then moved to jobs at Kodak and Dow Chemical. Drier, instead, got a degree in paper engineering from Western Michigan University in Kalamazoo, Michigan, and went to work in the pulp and paper industry. At age 30, he quit and enrolled at Salem. "Our family always kind of worked with our hands. Engineering is fascinating, but at the end of the day you don't have much to show," said Drier, 55. "With glassblowing, you have something at the end of the day that you've done." He came to UW-Madison in 2000 after working as a scientific glassblower at a chemical company in Milwaukee. Having a background in engineering isn't essential, "but I think it's what helped me get this job here," he said. "Breaking things down, critical thinking, is definitely a plus. But also, creativity is a plus," Drier said. "You have a drawing, and it doesn't matter how you get there. That's one of the nice things about this there's more than one way to do it." Drier has become something of an ambassador for the field of scientific glassblowing. He takes his Wisconsin FireWagon to schools and works with students from the glass program at UW-Madison. He also presents papers and shares tips with fellow members of the American Scientific Glassblowers Society, or ASGS. "I'll share anything that can be useful to the next guy," he said. At UW-Madison, "I'm one guy here. I don't know everything. So having the network to say, 'Hey, Jimmy I've never done these platinum seals. Can you give me something to work with?' There are a number of books, but nothing beats having someone who's done it before." The approximately 500 ASGS members include about 200 who are professional scientific glassblowers, said Jim Cornell, ASGS office co-manager. He estimates about 40 or 50 work in universities. Drier is the only scientific glassblower employed at UW-Madison. The society's membership also includes students, international members, independent glassblowers and even those who create "functional art" glass paraphernalia that's useful in a day when the legalization of medical marijuana is becoming more commonplace. On the science end of things, "there are not enough scientific glassblowers in this world," said Drier, who makes the job look easy. That's mainly thanks to "practice, practice, practice." And patience. "That would be the thing do you have patience? Because this thing will eat you alive if you don't," he said. "Glass breaks. For people watching, I would imagine it's like watching paint dry. It's a very slow process. Each of the steps is hand-work, and it does not go fast." But Drier also loves the puzzles he must solve to turn a researcher's ideas and diagrams into a working piece of the lab. "One of the beautiful things with this job, specifically, is the collaboration with the scientists," he said. "That's some serious science these guys are doing, state of the art, and I get to work with them. They tell me about it, and it's exciting for me." At the West Side home he shares with wife Amy Anderson, Drier has a shop in his garage for his main hobby: more glassblowing. "Honestly, what I do here helps me with what I do at home, and what I do at home helps me here," he said. "This is the greatest job I've ever had. I can't say enough about it," Drier said. "And I think everybody should be a scientific glassblower." ___ Information from: Wisconsin State Journal, http://www.madison.com/wsj Claim: Wisconsin glassblower customizes glassware for scientists.

A:
When Tracy Drier comes to Science Expeditions, the annual public open house held across the UW-Madison campus, he'll arrive with a wealth of scientific glassblowing knowledge and, of course, his Wisconsin FireWagon.
