The romaine lettuce outbreak has many consumers thinking about where their crops are grown.One rooftop greenhouse company in Chicago says their lettuce is safer and longer-lasting.Jenn Frymark, the chief agriculture officer and manager of Gotham Greens, pulls out a head of lettuce and immediately starts to eat it."No, you don't need to wash it,” Frymark says. “We don't have that on our package, but there's no reason for me to wash it. I never wash any of our lettuce at home. It's amazing; nothing touches it; it’s so clean.”Here at Gotham Greens, lettuce is grown differently.  They do it hydroponically. That means it’s grown without soil, but in a nutrient-rich water. Instead of a traditional farm field, this lettuce is grown on rooftop greenhouses.Their space on Chicago's south side is the largest rooftop greenhouse in the country.  Because of the controlled environment, crops can grow in a third of the time of a traditional field.“We're giving this plant everything it wants: the right day temp, the right night temp, the nutrients, CO2 levels, air circulation, the water,” Frymark explains. “I mean, these are very coddled plants and they have everything they need, and they can just grow in this perfect environment and reach maturity very quickly.”Gotham Greens sells to grocery stores in the Chicago and New York metro areas, as well as select Whole Foods stores. The product goes from the greenhouse directly to grocery shelves in a day and a half.The company’s lettuce also lasts longer than the traditional grocery lettuce out here. Frymark says their product can last up to two to three weeks in the fridge. Additionally, Gotham Greens prices are comparable to other organic produce.Frymark also says their method dramatically lowers the risk for foodborne illness.“There [are] no manures, there’s no water sources that could be contaminants,” she says. “We don't have birds and animals getting into the field.”She says the company is expanding and plans to open more rooftop greenhouses in the near future. 2053

The Smithsonian National Zoo in Washington is welcoming its newest member — a baby Lowland gorilla.On Sunday, 15-year-old Calaya gave birth to a son, Moke — "junior" or "little one" in Lingala, a language spoken in Central Africa.“The birth of this western lowland gorilla is very special and significant, not only to our Zoo family but also to this critically endangered species as a whole,” said Meredith Bastian, the National Zoo's curator of primates, according to the Smithsonian. “The primate team’s goal was to set Calaya up for success as best we could, given that she is a first-time mother. Doing so required great patience and dedication on the part of my team, and I am very proud of them and Calaya.”According to the zoo, Cayala has been adjusting well to motherhood and has learned how to care for Moke by watching other gorillas and through the help of staff. Zookeepers helped trained Cayala, in part, by showing her pictures of mother gorillas and presenting her with toys to cuddle and kiss.“This infant’s arrival triggers many emotions—joy, excitement, relief—and pride that all of our perseverance in preparing Calaya for motherhood has paid off,” said animal keeper Melba Brown. “We will provide support to her if need be, but I have every confidence that Calaya will be a great mom to Moke. I am excited to see how he will fit into the group dynamic. There are a lot of different personalities in this family troop, but they all work well together.”Alex Hider is a writer for the E.W.

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 stock market is on the comeback trail.After another wobbly session, the Dow soared 287 points, or 1.2%, on Friday. It was the index's best day since August.The Dow had soared 400 points at the open before giving up most of those gains and then resuming its rally. The Dow lost 1,378 points over Wednesday and Thursday.The broader S&P 500 jumped 1.4% on Friday. The Nasdaq, which has taken the brunt of the recent stock market turbulence, spiked 2.3%.Despite Friday's rebound, all three major indexes suffered their worst weeks since March. And the S&P 500 is down three straight weeks. That hasn't happened since the Brexit referendum of June 2016.Investing experts weren't exactly sure what turned stocks negative by midday. The driving forces behind this week's downturn -- trade war and interest rate fears -- were around before this week, and yet market volatility is spiking."The sellers have control right now," said Justin Walters, co-founder of Bespoke Investment Group. "The scariest sell-offs are the ones you can't tie to a specific reason."Stocks had turned sharply south over the past week because investors are concerned about rising interest rates. As the Federal Reserve raises rates to keep the economy from overheating, investors have been getting out of bonds, driving down their price and driving up their yields. Suddenly, the return on bonds has become competitive with some stocks — particularly risky tech stocks.Rising interest rates also increase borrowing costs for households and businesses, eating into corporate profits."What we are seeing now is changing sands. The ground isn't stable and people are figuring out where to go next," said JJ Kinahan, chief market strategist with TD Ameritrade.Tech stocks have come under fire because they are some of the riskiest and most expensive parts of the market. Investors fear that tech companies may not hold up well in a downturn, particularly as interest rates spike. A proxy for the tech sector had its sharpest plunge in seven years on Wednesday.But Big Tech on Friday regained some of its losses. Facebook (FB), Apple (AAPL), Amazon (AMZN), Netflix (NFLX) and Google (GOOGL) were all up.Asian and European markets also came back Friday. The Hang Seng soared 2.2%. Stocks in Shanghai rose 0.9% and the Nikkei rose 0.5%. Stocks in London, Germany and France all rose about a half percentage point.Markets had bounced back Friday morning following news that President Donald Trump plans to meet next month with Chinese leader Xi Jinping at the G-20 summit. That eased some of the investors' fears about another trade war escalation. China also reported its exports rose nearly 15% in September, stronger than expected. That suggests China is weathering the first waves of new tariffs that the Trump administration imposed on billion of Chinese exports this summer.But Kinahan is still worried about US-China trade talks. He thinks that a deal is key in order for the markets to get back on track, adding that a full-blown trade war could undo much of the positives from the Trump administration's pro-business policies."The concern is that if nobody blinks, it could negate all the tax cuts we had," he said.Earnings season also kicked off Friday morning, with JPMorgan (JPM) and Citigroup (C) reporting their quarterly finances before the bell. Wall Street analysts expected the financial sector to post another incredibly profitable quarter — and JPMorgan managed to?beat their already lofty expectations.In times of market turbulence, there's nothing like soaring profits to calm investors' nerves.Rebounds after disastrous market selloffs are common. Investors who think the market may be oversold look to buy stocks they think are suddenly cheap.But markets are fickle. 3804

The State of Utah sent face masks showing a handgun and controversial political image to a Salt Lake City family.The free masks are part of the “A Mask For Every Utahn” campaign, where federal COVID-19 money purchased more than two million masks to stop the spread of the virus.“I was just shocked,” said Chrstine Passey-Spencer outside her Rose Park home.Two masks delivered to the family show an American flag with a handgun printed across them with “Don't Tread on Me” written below a coiled rattlesnake.“I think the thing that bothered me most is that I knew my tax dollars paid for this and this is very politically charged speech,” Passey-Spencer said.The “Don't Tread on Me” image stems from the Revolutionary War but has become controversial in recent years. The Gadsden Flag has been used by the Tea Party, anti-gun control activists and white supremacists.In 2016, it was deemed to have “racially-tinged” messaging in some contexts by the federal government.More recently, the image has been used by people believing COVID-19 health restrictions take away their constitutional rights.“We hope this is an isolated incident that we just missed these couple of masks,” said Governor’s Office of Economic Development’s Ben Hart, who oversees the state’s mask program.Since April, the state purchased millions of masks from local and international manufacturers.Hart admits about 100 of the “Don't Tread on Me” masks were included in a shipment last month. Hart says the staff deemed them “inappropriate” and attempted to set all of them aside.“We will not be using taxpayer dollars to pay for these masks. We will be working with the manufacturer and ensuring we do not pay for them,” said Hart.The governor’s office replaced the masks for Passey-Spencer on Tuesday.KSTU's Hailey Higgins first reported this story. 1828
