The U.S. has carried out the first federal execution in nearly two decades, putting to death a man who was convicted of killing an Arkansas family in the 1990s in a plot to build a whites-only nation in the Pacific Northwest. Forty-seven-year-old Daniel Lewis Lee, of Yukon, Oklahoma, died Tuesday after receiving a lethal injection at the federal prison in Terre Haute, Indiana. Lee said before his execution that he was innocent. “I didn’t do it,” Lee said just before he was executed. “I’ve made a lot of mistakes in my life, but I’m not a murderer. ... You’re killing an innocent man.” 597

The U.S. has now seen two straight weeks in which at least 100,000 people are confirmed to have contracted COVID-19 each day.On Monday, the U.S. reported 166,000 new cases of the virus, marking the 14th consecutive day with 100,000 or more new cases of the virus, according to a database kept by Johns Hopkins University.The last day new cases totaled less than 100,000 was on Nov. 2. Since then, about 1.9 million Americans have contracted the virus, the rolling 7-day average of hospitalizations across the country has increased from 50,000 to 65,000 and daily deaths on a rolling 7-day average have ticked up from 824 a day to 1,114 a day.That 14-day time span has also seen seven days in which record numbers of new cases were reported. The current record was set on Friday when 177,000 people in the U.S. were confirmed to have contracted COVID-19.The current spike in caseloads has led hospitals across the country to become inundated with patients, overwhelming resources. The COVID Tracking Project reports that most of those hospitalizations are occurring in the Midwest, where rural hospitals in places like Iowa and South Dakota are running short on bed space.The current standard was predicted in June by Dr. Anthony Fauci, the nation's highest-ranking infectious disease expert. During a Senate hearing, Fauci stunned lawmakers by predicting that the U.S. could reach a point where 100,000 people were being infected each day if "disturbing trends" continued.Fauci's comments in June came during a summer spike in cases which saw infection rates top out at about 77,000 new cases each day.The current spike in cases comes as drugmakers like Pfizer and Moderna have reported encouraging results in vaccine trial results. While both vaccine candidates are on track for Emergency Use Authorization by the end of 2020, the drug likely won't be widely available to the general public for several months — Fauci has predicted that a vaccine will be widely available in the U.S. by April. 2002

The recommended amount of sleep for adults is six to eight hours a night. Sleeping more than those hours is associated with an increased risk of death and cardiovascular diseases, says a global study published Wednesday in the European Heart Journal.Looking at data from 21 countries, across seven regions, the research team found that people sleeping more than the recommended upper limit of eight hours increased their risk of risk of major cardiovascular events, like stroke or heart failure, as well as death by up to 41%.But a possible reason for this could be that people have underlying conditions causing them to sleep longer, which in turn could raise the risk of cardiovascular disease or mortality, explain the authors of the study.The team, led by Chuangshi Wang, a Ph.D. student at McMaster and Peking Union Medical College in China, also identified a rising risk among daytime nappers."Daytime napping was associated with increased risks of major cardiovascular events and deaths in those with [more than] six hours of nighttime sleep but not in those sleeping [less than] 6 hours a night," Wang said.In those who underslept, "a daytime nap seemed to compensate for the lack of sleep at night and to mitigate the risks," Wang explained.Previous studies into this topic were mainly carried out in North America, Europe and Japan. The new study brings a global picture.But the findings are observational, meaning the cause of this association remains unknown."Even though the findings were very interesting they don't prove cause and effect," said Julie Ward, a senior cardiac nurse at the British Heart Foundation, who was not involved in the study.Having less sleep -- under six hours -- was also shown to increase these risks by 9%, compared with people who slept for the recommended six to eight hours, but this finding was not considered to be statistically significant by the team.In 2014, 35.2% of American adults reported not getting enough sleep with less than seven hours per night, according to the CDC. 2049

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
