Paragraph: Democrats on a subcommittee of the House of Representatives Committee on Oversight and Reform released a cache of internal Juul emails and other documents that committee staff described as early attempts to "enter schools and convey its messaging directly to teenage children." Juul's use of social media influencers to promote its vaping devices in the years after it launched in 2015 also came under scrutiny. James Monsees, Juul's co-founder and chief product officer, told the committee that the company's target audience from the beginning has been adult cigarette smokers. Among efforts cited in the Juul documents released were a $134,000 payment to set up a five-week "holistic health education" summer camp at a Maryland charter school, recruiting children from third through 12th grades, and offering $10,000 to schools using the company's "youth prevention and education" programs for students, including those caught using e-cigarette products. "You don't think that sounds strange at all?" Representative Katie Hill, a Democrat, asked Juul's chief administrative officer, Ashley Gould. "All of these educational efforts were intended to keep youth from using the product," Gould responded. When Juul realized how the school involvement could be perceived as negative, "we stopped the program," she said. In a statement after the hearing, Juul said the $134,000 donation was to "facilitate already-existing community outreach and youth-prevention programs," and said the company "did not have any direct interaction with the students." Several committee members said Juul's initiatives appeared similar to past efforts by the tobacco industry to reach young people under the guise of smoking prevention programs. Gould said Juul, which is 35 percent owned by Marlboro maker Altria Group Inc (MO.N), halted its program last year once it became aware of the tobacco industry's past moves. Caleb Mintz, 17, a New York city high school student, testified at a separate hearing on Wednesday that a Juul representative came to his school as part of an educational program on mental health and addiction last year. He said in an interview Thursday that students received "mixed messages" about the product, being told it was safe but not to buy it. Mintz said after the hearing that the Juul presentation seemed to be "playing to the side of teens as rebellious. When a teen is told not to do something, they're more likely to do it." Members of the committee also quizzed Gould and Monsees over the use of social media influencers to promote Juul's vaping devices. Company executives early on agreed that "younger consumers age 25 to 34 was going to be the target of our initial campaign," Monsees said. "They would be more receptive to new technology solutions," such as the Juul device. Amid an enormous uptick in teenage use of e-cigarettes in 2018 a 78% increase among high school students from 2017 to 2018, according to federal data Juul said it ended all social media advertising last fall. Juul also pulled many flavored nicotine pods, except mint, menthol and tobacco, from retail stores, which Monsees said represented more than half of the company's sales at that time. Claim: U.S. lawmakers grill e-cigarette maker Juul over efforts targeted at schoolchildren.
E-cigarette maker Juul Labs Inc funded a "holistic health education" camp as part of efforts to market directly to school-aged children, members of a U.S. congressional panel said on Thursday, citing internal company documents.

Paragraph: We'll give the story a "N/A" in this category since it makes clear early on that this research is in the earliest of stages, done in an animal model, and says clearly that clinical trials are a future hope. This is way too early to consider costs which, we assume, would be substantial. The story says the stem cell intervention extended the rodents' lives "by 10-15% compared to untreated animals." At another point, it said, "the mice lived longer than controls, typically several months more, an increase of about 15%." The story makes no mention of the potential harms that might arise from this approach. Since this has never been tested in humans, we have no idea what they risks are. The story needed to point this out. Theoretically, the stem cells would have to be delivered into human brains via injections, which would make the intervention incredibly risky and possibly a non-starter. In the original paper, the stem cells were injected into the hypothalamus of the mice using viruses as "vectors." The researchers used lentiviruses, which are used often as vectors for research, but can be deadly in humans. Some discussion of this hurdle also was warranted. The story does a good job at explaining various aspects of the research and depicting the stages through which the research team drew its conclusions. It also is up front about this being animal research, so far untried in humans at even the earliest stages of clinical trials. Of note, the original paper mentions that this study was conducted in very few mice (total of about 20) and only in male mice. That detail would have been useful to include. One thing we wanted to point out that was problematic: The story said "if a similar extension was achieved in humans, a person with a life expectancy of 80 years could live to 92." We have no idea how this may impact humans; the evidence doesn't support that kind of speculation. The story doesn't appear to commit disease mongering, though it could have pointed out that aging in and of itself is not a disease. The story does quote one source unaffiliated with the research and we didn't detect any conflicts of interest. (The paper itself notes that the authors of the study have no conflicts of interests.) The story is all about basic research that suggests an approach that one day might slow, or possibly reverse, the aging process. There are no real alternatives available now to affect the aging process beyond lifestyle choices that might be healthier and appropriate treatments for illnesses that might otherwise shorten lifespans. It's clear from the story that this research is preliminary. The story clearly says, "The next step is to create human neural stem cells in the lab for testing." It also states that, "Researchers at Albert Einstein College of Medicine in New York hope to launch clinical trials of the procedure soon, but must first produce supplies of human neural stem cells in the lab which can be implanted into volunteers." The story heralds this research as a "tour de force" and a "breakthrough." Yet is it accurate in a news story to call anything done in animals a "breakthrough?" That word implies relevance to humans, and this is far from established in a mouse study. Studies in mice are essential but many of them fail to show similar evidence in humans. Likewise, stem cell research is often seen as a magic bullet for some conditions but there have been few cases where the preliminary hope/hype has born out. The story does not appear to rely on a news release. Claim: Stem cell brain implants could 'slow ageing and extend life', study shows
This story describes some interesting but very early research into the mechanisms of aging and how they might be altered. The story made it clear that this was mouse-level research and has several hurdles to go before it's ever tested in people. One weak point for the story was how the story assumed there might be benefits in people yet overlooked the potential risks. Considering this intervention involves inserting stem cells into the brain via the assistance of a viral strain known to be harmful to humans, it's logical to assume there could be some safety concerns. It also overplayed the novelty here by quoting an expert who called it a "tour de force" and a "breakthrough." The desire to somehow combat aging seems inherent in humans. If there is a fairly straightforward "switch" that can control the aging process and this story suggests so then this would be a major advance. Yet we are looking at decades before this becomes a rigorous Phase III human trial, let alone a potential intervention in humans. The bottom line is: We are talking about approximately 20 male mice.

Paragraph: Virtually unknown just months ago, New York congressional candidate Alexandria Ocasio-Cortez arrived in Los Angeles as a rising political star, about a month after her improbable upset of 10-term U.S. Rep. Joe Crowley in a New York City Democratic primary. On Thursday, she intentionally avoided politicians and Hollywood celebrities, instead choosing to share the stage at the low-dollar fundraiser with activists pushing for broader rent-control laws in California and a public-backed banking system in the city. In her speech, she warned of a broken economy in which luxury apartments stand vacant while homeless crowd the streets, and talked of a Democratic Party in which the working class and marginalized are ascendant. Bursts of applause followed her calls for universal health care and a cost-free education through college. She swiped repeatedly, if indirectly, at President Donald Trump. "It is not us who are crazy, not with that man in the White House," the former Bernie Sanders organizer said to cheers. Ocasio-Cortez was lauded by those who paid $27, or $10 for students, to see the candidate seen as the new face of the emerging democratic socialist movement. "She really inspires me, because she's so young and she's getting so far," said Melainey Jane Foerster, 16, a high-school student from suburban Santa Clarita. Salesman Jon Pelzer, 65, said he's "impressed by and energized by what she was able to do in New York." "We share all the same values," added Pelzer, a Democrat who ran on a similar platform in California's 30th Congressional District but didn't advance to November. The surprise victory by the political novice in a district that includes parts of the Bronx and Queens came after a low-budget campaign that she built around liberal and social causes, not the traditional Democratic Party machine. Crowley had been expected to win easily. Her platform includes expanding the Medicare program to people of all ages and abolishing Immigrations and Customs Enforcement. Her trip to California comes at a time when state and national Democrats have been contending with friction between their establishment and liberal wings. California Sen. Dianne Feinstein is being challenged in November by a fellow Democrat, state Sen. Kevin de Leon, who has positioned himself as a liberal alternative to the long-serving centrist. She warned of the influence of "coastal elites" in politics, and she recalled that her candidacy was largely dismissed. Ocasio-Cortez said she didn't receive an endorsement from any incumbent "but we won anyway." She urged the crowd to "engage in the fights that you know that are right." Claim: Rising liberal Democrat star on West Coast fundraising swing.
She visited Los Angeles' notorious Skid Row neighborhood, where the homeless crowd the streets. She met with liberal activists eager to see universal health care and expanded rent-control laws. And she was cheered by hundreds of supporters at a downtown fundraiser, where she warned of those who scheme to turn liberal-minded Americans against each other.
