The scariest thing at Wormtown Brewery in Worcester, Massachusetts this fall has nothing to do with Halloween. This small independent brewery ran out of aluminum cans for the first time in company history."We have had a couple of loads of cans canceled on us, but last week was the first time we truly ran out of cans," said co-owner David Field.Shipments of cans are becoming very rare for breweries and beverage producers nationwide. Americans are drinking less at bars and restaurants and more at home, putting greater demand on liquor stores and breweries like Wormtown.Typically, this craft beer producer would send out about 20 percent of their product in kegs to area bars, but because of the pandemic, close to 100 percent of the beer they produce is being sent directly to consumers."People drink more often at home; they drink more in small social circles," Field said.In the U.S., there are only a small handful of can distributors. Most years, they produced about 100 billion aluminum cans. However, this year, there's a nationwide shortage of close to 10 billion cans.Everyone-- from major soda companies to small craft breweries--has started to feel the impact. Part of the shortage is being caused by the explosion of hard seltzers into the market. Only making the situation worse, many recycling plants were forced to go offline during the spring.But, mostly, experts say the can shortage is simply being caused by supply and demand."It's going to catch up with everybody. If they haven’t been hit, they will be, and it looks like it’s gonna be a little while," Field added.Perhaps one of the biggest buzzkill for small breweries is if customers can’t find their product on a shelf, they might be gone for good and turn to another product that's more available. Field says that could have long-lasting impacts on his company's bottom line."That person who loves our beer might be introduced to somebody else’s beer they like and may not come back to us," he said.The problem is impacting brewers all over the country. The Brewers Association, which represents more than 5,000 breweries, says they're even hearing about some manufacturers having a difficult time getting glass bottles."There’s been a huge increase in demand for cans that then when the pandemic hit, was just accelerated. Not just with beer, but all package types to cans," explained Chuck Skypeck, who serves as the group's technical brewing projects manager.What it all means for the American consumer is fewer options for beer and other soft drinks as well. It’s a difficult task for the nation's brewers as they try their best to quench this country's thirst for beer. 2662

The Wake Forest Institute for Regenerative Medicine says it has a new use for its bioprinting system. In the past they've 3D printed normal-size organs and tissues in hopes of someday implanting them in patients.For the coronavirus, the lab is creating organs using human cells that can be as small as a pinhead. They're focusing on the organs most likely to be infected by the disease. like the lungs.“And so we've been playing with a number of agents to, on both prongs what can make it more infective, what can make it less infective to try to sort this out for the future,” Anthony Atala, director for the institute said.Atala says he hopes the system will help in testing drugs before they hit the market.Drug companies do extensive testing and clinical trials in people before releasing a new medication.Atala says sometimes those companies find no serious side effects, but then years later, discover that it's toxic to patients taking it. Atala says testing a drug using the bioprinting system can tell if a drug is toxic in weeks instead of after years on the market.“Even though we've used the tool extensively for toxicity testing, it's also a tool that can be used for screening,” Atala said. “So we can test agents that are currently being considered for testing against COVID and test the efficacy of the treatment on miniature human organs made up of normal cells”To be clear, Atala said drug tests on 3D printer organs are not meant to replace clinical trials in humans, be are an added step to better predict what will happen in those trials. 1567

The U.S. dollar is cooling off after a red-hot surge.Though it rose in the weeks following President Trump's election victory last November, the greenback has steadily fallen this year. It's now down to its lowest level since January 2015. Since January 3, the first trading day, the dollar is down 11 percent.It's down nearly 17 percent against the Mexican peso this year, a reversal of fortunes after Trump's campaign threats caused the peso to plunge. It's also down 12 percent against the euro and 7% against the pound. 541

The US economy added 155,000 jobs in November, the Labor Department reported Friday. That's fewer than expected, but the unemployment rate remained steady at 3.7%.October's jobs numbers were also revised down slightly, to put the monthly average over the past year at about 204,000 jobs, and the average over the last quarter at 170,000.The report is a sign of a slowing but still strong labor market — and further support for the idea that the Federal Reserve may hold off hiking interest rates over the next year as quickly or as much as initially planned.That's reassuring to investors who had been worried that the Fed would move too fast to cool off an already decelerating economy."My reaction is a sigh of relief," said Leo Grohowski, chief Investment Officer at BNY Mellon Wealth Management. "I think a mild miss is more than acceptable in order to help the Fed understand that multiple rate increases may not be warranted for 2019."Paychecks grew by 3.1% over the last year, a relatively robust number that is in line with expectations as employers have had to fight to attract workers in recent months.The percentage of people participating in the labor force remained the same and the median number of weeks people remained unemployed dropped from 9.4 to 8.9 weeks in November, suggesting that people are getting jobs more quickly after losing them.However, the number of people "marginally attached" to the labor force — those who had looked for a job in the past year but stopped in the past month because they couldn't find one — has risen by nearly 200,000 over the past year. The percentage of people working part time who would rather work full time also rose slightly.Despite high demand for workers in some sectors, that may show that people who want jobs increasingly aren't in the places where employers need them — and that the economy still has room to expand before running out of workers entirely.The strongest job growth came in health care, transportation and warehousing, and manufacturing, which added another 27,000 jobs for 288,000 total growth over the past year. Tariffs and fears of a larger trade war may not be having a huge positive impact, but they're definitely not choking the sector either.The-CNN-Wire? & ? 2018 Cable News Network, Inc., a Time Warner Company.
