Bloomberg School of Public Health and Temple University. The study, titled “The Effect of Medical Marijuana Laws on Health and Labor Supply,” appeared in the spring 2019 issue of the “Journal of Policy Analysis and Management.” It suggests medical marijuana laws may improve the health and employment prospects of older Americans. “Our study is important because of the limited availability of clinical trial data on the effects of medical marijuana,” says Lauren Hersch Nicholas, assistant professor in the Bloomberg School’s Department of Health Policy and Management. “While several studies point to improved pain control with medical marijuana, research has largely ignored older adults even though they experience the highest rates of medical issues that could be treated with medical marijuana.” Among those who had a health condition that would qualify for medical marijuana in their home state, a 4.8 percent decrease in reported pain and a 6.6 increase in reported "very good or excellent health" were seen in the responses from more than 100,000 survey participants older than 51, according to a statement on the study from the Bloomberg School. The data came from the data from the 1992-2012 Health and Retirement Study, which is the largest nationally representative survey to track health and labor market outcomes for older Americans. Researchers looked for responses and symptoms that might affect a subject’s ability to work.“The study found that medical marijuana laws lead to increases in full-time work,” a statement from the school said. Looking at the sample of survey participants who qualified for medical marijuana treatment, researchers found a greater increase in full-time work after laws allowing access to medical cannabis passed in those states. The study suggests that the potential negative effects medical marijuana may have on worker productivity are outweighed by the increased capacity of those under such treatment to work. The results of the study may inform policy discussions about medical marijuana, potentially broadening support for more research into its use as effective medical treatment, the school said. Currently marijuana’s status as a Schedule 1 drug at the federal level limits opportunities to study the substance and build evidence that could be used for treatment or policy decisions. Currently 33 states and Washington, D.C., have laws that legalize marijuana for medical use. 2439

YouTube Kids has struggled with disturbing videos, like beloved Disney characters in violent or sexual situations, sneaking past its automated filters.Now the app is adding new settings to give parents more control over what videos their kids can see.The company announced Wednesday an option to filter videos by "approved content only," so parents can whitelist channels and subjects.The effort comes four months after reports called attention to troves of videos with inappropriate themes on the video-sharing site's kid-friendly platform. Content for YouTube Kids is selected from the main YouTube app and screened using machine learning algorithms. But some videos, such as cartoons disguised as age appropriate, slip through the cracks.Once the new setting is turned on, users can pick collections from trusted creators such as PBS and Kidz Bop, or themed collections curated by YouTube Kids itself.YouTube is launching another tool later this year that will let parents choose every video or channel their kid can see in the app."While no system is perfect, we continue to fine-tune, rigorously test and improve our filters for this more open version of our app. And, as always, we encourage parents to block and flag videos for review that they don't think should be in the YouTube Kids app," the company said in a blog post announcing the new features.It's the kind of control parents have been asking for from the popular app, but it also puts the onus on them to filter content. It's a side effect of the way YouTube Kids finds its videos.When a video for children is uploaded to the main YouTube platform, it is not automatically added to the YouTube Kids library. The videos are reviewed by machine learning algorithms to determine whether or not they are appropriate for the app.The automated process -- one YouTube calls very thorough -- can take days. A human doesn't check the videos before they're added, but parents can flag videos they find alarming later and a content reviewer will check it out.However, it's unlikely parents are constantly watching YouTube Kids videos along with their children. It's possible this safety guard isn't sufficient for catching every odd video your kid might see.The flag-the-video-later system has created some problems for the service. Some YouTube creators have uploaded concerning videos marked as kids content that slips past the screening process. These videos have included Spiderman urinating on Frozen's Elsa, Peppa Pig drinking bleach, and Micky Mouse getting run over by a car.The company continues to change its rules to crack down on the issue, but creators are constantly looking for ways to trick the system.YouTube Kids still has its main library available by default for now, and the company says it is working on more controls for parents. 2837

-- meaning wind, humidity and other conditions are ripe for fires.The Hillside Fire is far from over -- officials urge about 1,300 people in an evacuation zone in the north of the city to stay away. But the flames were out in Valdavia's neighborhood by late morning, and Valdivia returned to find only charred remains of his house. He'd lived there a little more than a year."It hurts, but this can get replaced," he said. "You can't replace a life. That was my priority -- just my kids, and making sure everybody was aware."One thing he regrets not grabbing: a laptop with the only copies of some baby photographs of his kids."That's the only thing that hurts my feelings a lot -- pictures I didn't save," he said.The fire was first reported just north of San Bernardino around 1:40 a.m. PT (4:40 a.m. ET) and swept into neighborhoods on the city's edge, consuming about 200 acres by mid-morning, officials said.Authorities rushed to alert residents who'd been sleeping. No injuries have been reported.490 homes in San Bernardino evacuatedFirefighters were working to keep the fire from advancing Thursday."This fire moves so fast that it's imperative that people evacuate when we ask them to," San Bernardino County Fire Deputy Chief Kathleen Opliger said. "It's not a safe place to be."Evacuations have been ordered for about 490 homes in northern San Bernardino, the county fire department said.The fire was a few miles away from Cal State San Bernardino, which was closed Thursday because the regional utility intentionally cut power as a precaution, hoping to prevent fires in the red-flag conditions. The campus lost power at 3:20 a.m. Thursday.Julien Cooper, 53, and his father were sleeping in Cooper's San Bernardino home when he heard his phone ringing. He woke up and smelled smoke."Ten seconds later, I hear the doorbell and I already know what it is since we had a fire a week ago," he told CNN. "It was the neighbor saying that there was a fire in the field."Cooper grabbed his dad and his dog, crossed the street to help the neighbor's elderly mother evacuate and met up with a relative at a McDonald's. Minutes later he returned home and grabbed some valuables -- and his neighbor's home was on fire.Cooper took video of the neighbor's house engulfed in flames. His nephew Henri Moser, who lives out of state, shared it on Twitter. Cooper said he heard firefighters say they'd try to save his house, which had 2428

Worldwide markets plummeted again Thursday, deepening a weeklong rout triggered by growing anxiety that the coronavirus will wreak havoc on the global economy. The sweeping selloff pushed the Dow Jones Industrial Average down nearly 1,200, its biggest one-day drop ever.The benchmark S&P 500 dropped down4.4% Thursday, its worst one-day drop since 2011.The S&P 500 has now plunged 12% from the all-time high it set just a week ago. That puts the index in what market watchers call a "correction," which is decline of at least 10% from a high. The six-day correction is the fastest in history.Stocks are now headed for their worst week since October 2008, during the global financial crisis.The losses extended a slide that has wiped out the solid gains major indexes posted early this year. Investors came into 2020 feeling confident that the Federal Reserve would keep interest rates at low levels and the U.S.-China trade war posed less of a threat to company profits after the two sides reached a preliminary agreement in January. Even in the early days of the outbreak, markets took things in stride.But over the past two weeks, a growing list of major companies issued warnings that profits could suffer as factory shutdowns across China disrupt supply chains and consumers there refrain from shopping. Travel to and from China is severely restricted, and shares of airlines, hotels and cruise operators have been punished in stock markets. As the virus spread beyond China, markets feared the economic issues in China could escalate globally.One sign of that is the big decline in oil prices, which slumped on expectations that demand will tail off sharply."This is a market that's being driven completely by fear," said Elaine Stokes, portfolio manager at Loomis Sayles, with market movements following the classic characteristics of a fear trade: Stocks are down. Commodities are down, and bonds are up.The Dow dropped 1,190.95 points, its largest one-day point drop in history, bringing its loss for the week to 3,225.77 points, or 11.1%. To put that in perspective, the Dow's 508-point loss on Oct. 19, 1987, was equal to 22.6%. Bond prices soared again Thursday as investors fled to safe investments. The yield on the benchmark 10-year Treasury note fell as low as 1.246%, a record low, according to TradeWeb. When yields fall, it's a sign that investors are feeling less confident about the strength of the economy.Stokes said the swoon reminded her of the market's reaction following the Sept. 11, 2001 terrorist attacks."Eventually we're going to get to a place where this fear, it's something that we get used to living with, the same way we got used to living with the threat of living with terrorism," she said. "But right now, people don't know how or when we're going to get there, and what people do in that situation is to retrench."The virus has now infected more than 82,000 people globally and is worrying governments with its rapid spread beyond the epicenter of China.Japan will close schools nationwide to help control the spread of the new virus. Saudi Arabia banned foreign pilgrims from entering the kingdom to visit Islam's holiest sites. Italy has become the center of the outbreak in Europe, with the spread threatening the financial and industrial centers of that nation.At their heart, stock prices rise and fall with the profits that companies make. And Wall Street's expectations for profit growth are sliding away. Apple and Microsoft, two of the world's biggest companies, have already said their sales this quarter will feel the economic effects of the virus.Goldman Sachs on Thursday said earnings for companies in the S&P 500 index might not grow at all this year, after predicting earlier that they would grow 5.5%. Strategist David Kostin also cut his growth forecast for earnings next year.Besides a sharply weaker Chinese economy in the first quarter of this year, he sees lower demand for U.S. exporters, disruptions to supply chains and general uncertainty eating away at earnings growth.Such cuts are even more impactful now because stocks are already trading at high levels relative to their earnings, raising the risk. Before the virus worries exploded, investors had been pushing stocks higher on expectations that strong profit growth was set to resume for companies after declining for most of 2019. The S&P 500 recently traded at its most expensive level, relative to its expected earnings per share, since the dot-com bubble was deflating in 2002, according to FactSet. If profit growth doesn't ramp up this year, that makes a highly priced stock market even more vulnerable.Goldman Sach's Kostin predicted the S&P 500 could fall to 2,900 in the near term, which would be a nearly 7% drop from Wednesday's close, before rebounding to 3,400 by the end of the year.Traders are growing increasingly certain that the Federal Reserve will be forced to cut interest rates to protect the economy, and soon. They are pricing in a 96% probability of a cut at the Fed's next meeting in March. Just a day before, they were calling for only a 33% chance, according to CME Group.The market's sharp drop this week partly reflects increasing fears among many economists that the U.S. and global economies could take a bigger hit from the coronavirus than they previously thought.Earlier assumptions that the impact would largely be contained in China and would temporarily disrupt manufacturing supply chains have been overtaken by concerns that as the virus spreads, more people in numerous countries will stay home, either voluntarily or under quarantine. Vacations could be canceled, restaurant meals skipped, and fewer shopping trips taken. "A global recession is likely if COVID-19 becomes a pandemic, and the odds of that are uncomfortably high and rising with infections surging in Italy and Korea," said Mark Zandi, chief economist at Moody's Analytics. The market rout will also likely weaken Americans' confidence in the economy, analysts say, even among those who don't own shares. Such volatility can worry people about their own companies and job security. In addition, Americans that do own stocks feel less wealthy. Both of those trends can combine to discourage consumer spending and slow growth.MARKET ROUNDUP:The S&P 500 fell 137.63 points, or 4.4%, to 2,978.76.
