Dangalabba, a nearly 14-foot Estuarine Crocodile, has now made its home at the Perth Zoo in Australia after being rescued after officials feared for the crocodile's safety. Dangalabba was rescued from a crocodile farm in Broome, Australia, which is clear 1,400 miles from Perth. Dangalabba then made the journey to the Perth Zoo in a climate-controlled truck. "Dangalabba’s move to Perth was no small feat," the Zoo said. "It was planned to precision and involved a climate-controlled truck to keep the crocodile as happy and comfortable as possible, whilst a roster of truck drivers drove continuously so we could complete the 2000km+ journey quickly and safely."On Thursday, Dangalabba jumped into his pool, which is kept at 80 degrees. The Perth Zoo said that the the Estuarine Crocodile was hunted intensely and was listed as a threatened species. It has since been removed from the threatened species list in Australia. 937

DENVER — While riding on two wheels, bicyclist Mike Stejskal has one goal: safety.The long-time bike rider knows how sketchy sharing the streets with cars can be.“The traffic volume is too high and it's stressful interacting with all the cars.,” Stejskal said while riding. "There’s way more chill routes." So before going out for a spin, Stejskal maps out at all the routes that will get him to where he’s going in the least amount of danger.“To me, I don’t understand why we would pick as the same place to send cyclists down as buses,” he said. Now, 565

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

  

Cosmetic products such as perfume, nail polish and shampoo help us feel and look good. But in the wrong hands -- especially those of the very young -- these products can be harmful, or even deadly. More than 64,000 kids in the United States younger than 5 years old had a cosmetic-related injury between 2002 and 2016, according to estimates in a study published Monday in the journal Clinical Pediatrics.Researchers looked at the type of product, route of exposure, location of the injury and other factors in children younger than 5 who were treated in US emergency departments. The findings came from the National Electronic Injury Surveillance System, a database operated by the US Consumer Product Safety Commission that reports on injuries and poisonings involving consumer products.The study noted that from 1999 through 2015, cosmetics were the cause of seven deaths among children, according to the National Poison Data System."Although a cosmetic product may not be harmful when used according to the directions, it is important for parents and caregivers to know that a young child could be seriously injured by these products," Rebecca McAdams, a research associate at Nationwide Children's Hospital and an author of the study, said in an email.The cosmetics most likely to cause injuriesThe authors defined cosmetic products as those that "cleanse, beautify, promote attractiveness, or alter appearance." These include hair relaxers, nail polish, moisturizers, skin oils, deodorants and make-up. The products were categorized into five groups, based on how they're used: nail care, hair care, skin care, fragrance and other, which included deodorants and make-up.The most common injuries came from nail care products (28.3%), followed by hair care products (27%), skin care products (25%) and fragrance (12.7%). About 75% of the injuries occurred when children swallowed products. The remaining exposures came from skin or eye contact. Patients were most likely to be hospitalized after exposure to hair products.The products most likely to land children in the hospital? Hair relaxers and permanent solution. Children exposed to them were more than twice as likely to have a chemical burn and more than three times as likely to be hospitalized, when compared to all other products.The study also found that younger children had a higher risk for injury and hospitalization, with the average rate of injury in children less than 2 years old being two times higher than children between the ages of 2 and 4. Those younger than 2 were also more likely to be injured from hair products.Stages of childhood development could account for these injury risks, the study's authors wrote. By 6 months of age, many kids can crawl and grab things to put in their mouths. They can pull themselves upright and walk by the time they're 1 year old, which allows them to close doors and reach across counters."These new abilities and the natural curiosity that accompanies them, coupled with a lack of previous experience in discriminating between harmful and neutral or pleasant stimuli ... can help explain why children less than 2 years of age are at greater risk," McAdams wrote.'People don't childproof their homes'Each year, doctors in emergency departments across the country treat about 4,300 young children with cosmetic-related injuries on average. The number and rate of these injuries did not significantly change across the 15 year period. This highlights the need for better cosmetic product injury prevention strategies, the study authors wrote."People don't childproof their homes, which I say without judgment because my toddlers have gotten into numerous dangerous items and I do this for a living," Dr. Emily MacNeill, a pediatric emergency medicine doctor at Carolinas Medical Center in Charlotte, North Carolina, said in a text message. MacNeill was not involved with the study.The study had limitations, including the fact that the data came only from US emergency departments and didn't include cases that were treated at home, urgent care or pediatric offices. Emergency departments may also have different standards for documenting injuries, the authors noted.While the study didn't show any increases in cosmetic-related injuries, it raises awareness that people shouldn't "underestimate the danger of certain products, hair products specifically," MacNeill wrote.The best thing parents and child caregivers can do is to keep their cosmetic products stored safely and in their original containers. The American Academy of Pediatrics recommends storing cosmetic products like medications -- locked in a place that's high and out of sight for young children.If a child is accidentally exposed to a cosmetic product, parents and caregivers can call the national poison help line at 1-800-222-1222. 4829
