The Maine State Police are launching a Cold Case Deck of Cards initiative to generate leads for unsolved cases. "The deck features 52 of Maine State Police’s unsolved homicides and suspicious missing person cases and will be distributed to inmates in correctional facilities across the state," reports Jim Leonard of the Midcoast Villager. "This marks the first time the concept has been implemented in Maine. Similar initiatives in more than two dozen states have been credited with helping solve multiple homicide investigations."

Just because cranberries are tart doesn't mean they require a ton of sugar to become tasty. "Diabetics or anyone who wants to reduce the added sugars they’re consuming can try a few culinary tactics to lower their sugar intake while still enjoying this holiday treat," writes food scientist Rosemary Trout for The Conversation. "Don’t cook your cranberries much longer after they pop. You’ll still have a viscous cranberry liquid without the need for as much sugar. … For a richer flavor and a glossy quality, add butter. … Adding chopped walnuts, almonds, or hazelnuts can slow glucose absorption, so your blood glucose may not spike as quickly."

In a tribute to snail mail and history buffs, a new podcast, "People of Agency," offers listening excursions into "the stories of individuals who have shaped USPS over its 250-year history," reports Sean Michael Newhouse of Government Executive. The show is co-created and co-hosted by Aileen Day, a political communications consultant, and Maia Warner-Langenbahn, who co-hosts the "Well, I Laughed" podcast. In the show's first episode, the duo recount the story of Mary Katherine Goddard, who was "put in charge of Baltimore’s mail in 1775 and printed the first copy of the Declaration of Independence that listed all of its signatories."

In a bid to have more control over production and supply, Walmart recently opened its "second U.S.-owned milk processing facility in Valdosta, Ga., a $350-million plant supplying milk to more than 650 Southeast stores," reports Taylor Leach of Dairy Herd. While the company does purchase milk from local farmers, "some critics have warned Walmart buys milk from only a handful of large farms, putting smaller farms under further pressure. … The opening also follows Walmart’s recent investments in case-ready beef plants in Thomasville, Ga., and Olathe, Kansas."

Shaking your real Christmas tree before bringing it 
into your home can keep bugs from coming inside.

The holidays can be full of surprises, but discovering six-legged stowaways in your freshly cut Christmas tree shouldn't be one of them. "Bringing a real Christmas tree into your warm living room can accidentally wake up thousands of dormant bugs, turning your cozy holiday into a surprise visit from nature," reports Jenn Jordan of The Weather Channel. To prevent insect or spider visitors from entering your home, while your tree is still outside, give it more than one seriously hard shake. Many tree farms use mechanical shakers, which can also do the trick.

From the bubonic plague to cholera pandemics to deadly staph infections, bacterial illnesses often pose one of the biggest challenges to human survival. But with innovation, microorganisms can also help humans do remarkable things. "In the boulder-strewn desert east of Tucson, Arizona, miners are using sulfuric acid and bacteria to bring online the first new U.S. copper production in more than a decade," reports Ryan Dezember of The Wall Street Journal. Advances in technology are key to how this copper is mined. The enterprise uses "microbes to strip copper from ores that are otherwise uneconomical to mine." The Grand Canyon's state motto just happens to be Ditat Deus, which is Latin for "God Enriches." Last year, 70% of U.S. copper came from Arizona.

More states are restricting junk food purchases with Supplemental Nutrition Assistance Program benefits to increase the federal funding they receive. "Six more states agreed to ban the use of SNAP benefits for junk food under new deals with the Trump administration," reports April Rubin of Axios. "The new waivers restrict the purchase of non-nutritious items like soda, energy drinks, certain juices, prepared desserts and candy." While which foods and drinks are restricted varies by state, all states with added nutritional restrictions will all receive more federal dollars to support their SNAP programs.
