DENVER — Three unvaccinated children who are visiting Colorado from another state tested positive for measles after traveling to a country with an ongoing measles outbreak, according to a Tri-County Health Department news release on Monday.The children flew into Denver International Airport with their family Wednesday. DIA officials said people who were in concourse A, on the train to the terminal, the west baggage claim or at the west passenger pick up area on that day between 1:15 p.m. and 5:45 p.m. may have been exposed. However, DIA said there is no ongoing risk of exposure. The exposure risk in other areas of the city is unknown at this time. Health officials said they are working to identify people who may have been exposed to the highly contagious infectious viral disease.The three patients are currently being treated at Children’s Hospital in Aurora, according to the health department.More cases of measles have occurred in the US during 2019 than any year since 1992, according to the Colorado Department of Public Health and Environment. The last case of measles in Colorado was in January of this year.This article was written by Robert Garrison for 1186

DENVER, Colo. – Buying a Christmas tree can represent the start of the holiday season. But trees can be expensive. If you want it to last until the big day, there are simple steps to take when buying the perfect tree.Doug Brown is the owner of Reindeer Ranch in Denver, Colorado. He’s been selling Christmas trees since 1997. So, he knows a thing or two about what type of Christmas tree lasts the longest.Brown says, "the noble firs and the Fraser firs tend to be the Cadillacs of trees. Those are going to be the ones that give you the best look and the most longevity."When picking a tree on the lot, Brown suggests doing the touch and smell test. If no needles fall off and it smells like pine, it’s a healthy tree.As for the price of the tree, this year you might be paying a little extra.Brown says, “we are in a tree shortage right now." That means the demand outweighs the supply. Before you leave the lot, make sure you get a fresh cut on the bottom of your tree. That way it soaks up all the water when you bring it home.Once your home Brown says, "get it into your stand and put water in it right away no longer than 6 to 8 hours."Make sure to check the water daily. A tree drinks about a gallon of water a day.Also, never place your tree next to a vent, fireplace or window because that will dry out the tree. There’s also no need to put fertilizer or Miracle Grow in the water.Brown says, if you follow these simple tips, you and your loved ones will be enjoying your perfect tree the entire holiday season.Brown is not only selling trees this year. He is also holding a toy drive too. On Saturday, December 14, they will be giving away 200 toys to families in need. The toy drive starts at 10 a.m. 1723

Dinosaurs are no longer roaming the earth, but their tracks live on. In the foothills on the Front Range of Colorado, a story can be told from pieces of the past left behind.Dinosaur Ridge has been ranked by a panel of esteemed paleontologists as the no. 1 track site in all the U.S. One of those world-renowned paleontologists is Martin Lockley, who has spent his life studying dinosaur tracks.“You're looking at a snapshot of an ancient environment," Lockley says.In an area of just a few hundred square feet, 330 dinosaur tracks have been discovered. However, the land was very different 100 million years ago. Lockley says the giant prehistoric animals weren't a mile high in the Rocky Mountains.They were on the beach at sea level in an environment very similar to present day Gulf of Mexico.“We like to joke and call this beach-front property a 100 million years ago," Lockley says.The soft, wet, sandy land made conditions ideal for preserving tracks."If they're walking on wet sediment, like a beach or a mud flat or the shores of a lake, and it dries out, it becomes hard like concrete," Lockley explains. "And the next time there's a flood washing in more sediment, it will bury those tracks without them being eroded away."Experts believe three different dinosaurs made their mark on this patch of land. Lockley says it's possible they were migrating along what used to be a coast. It's clear the western U.S. was a popular place to be, because there are more than 120 dinosaur track sites from Kansas to Utah. Martin suggests part of the reason is less vegetation in these states means more fossilized rock is exposed.But if there are so many track sites, what makes Dinosaur Ridge the top of all track sites? Executive Director Jeff Lamontagne, with Friends of Dinosaur Ridge, says there was a list of criteria the panel considered."How many tracks there are, the variety of dinosaurs seen in the tracks, the importance of the tracks, the clarity of the tracks, the accessibility and number of visitors," Lamontagne explains.Accessibility is the main reason Dinosaur Ridge has become so highly regarded."It's right outside a major metropolitan area, and there's a major road just a quarter mile from here," he says. "It's easy to see this compared to most other dinosaur track sites in the United States and in the world."People can get so close to the tracks; in some places you can even touch them. Although the tracks have been well-preserved for millions of years, their current exposure to humans and the elements could make them erode over time.Thankfully, with current technology, scientists can scan the surface and re-create it as 3-D permanent record. They also plan to build a cover to protect the land.However, Friends of Dinosaur Ridge believe the hands-on part of the site is important for kids to continue learning about the planet's past. A past that can teach us about topics like climate change, evolution and extinction."We used to think that the dinosaurs all went extinct, but then we realized that some of them survived and evolved into birds," Lockley says.For modern-day humans, Dinosaur Ridge will continue to be an intriguing learning opportunity, reminding people we aren't the only ones to experience life on Earth."It gives you a sense of wonder to imagine these enormous beasts living, playing, dying, a hundred million years ago," Lamontagne says.********************************************If you'd like to reach out to the journalist for this story, email elizabeth.ruiz@scripps.com 3540

Drinking coffee could activate the body's fat-fighting defenses, a discovery that could have potential implications in the battle against obesity and diabetes.In a study published Monday, researchers at the University of Nottingham said that coffee may help stimulate our brown fat reserves, also known as brown adipose tissue, which play a key role in how quickly we can burn calories.There are two forms of fat cells, brown cells and white cells, and each plays a different role in our metabolism.While brown cells help generate heat, white cells are responsible for the storage of fat -- or, energy -- ready for release as needed. Levels of brown fat are known to be high in children but recent findings on the presence of brown fat in adults has restored hope to use them as targets to treat obesity."Brown fat works in a different way to other fat in your body and produces heat by burning sugar and fat, often in response to cold, said professor Michael Symonds, from the School of Medicine at the University of Nottingham, who co-directed the study."Increasing its activity improves blood sugar control as well as improving blood lipid levels and the extra calories burnt help with weight loss. However, until now, no one has found an acceptable way to stimulate its activity in humans."The scientists started by testing out coffee on stem cells to see if it would stimulate brown fat. Once they found the right dose, they moved on to humans to see if the results were similar.The team used a thermal imaging technique on four men and five women to trace the brown fat reserves and see how it produced heat."From our previous work, we knew that brown fat is mainly located in the neck region, so we were able to image someone straight after they had a drink to see if the brown fat got hotter," Symonds said.So will drinking a cup of coffee help you lose weight, as well as get out of bed?The study only involved nine people and the research is still at a very early stage. Scientists say they still need to determine what it is exactly about coffee that busts fat."The results were positive and we now need to ascertain that caffeine as one of the ingredients in the coffee is acting as the stimulus or if there's another component helping with the activation of brown fat," Symonds said."Once we have confirmed which component is responsible for this, it could potentially be used as part of a weight-management regime or as part of glucose regulation program to help prevent diabetes." 2507
