A wet spring in Las Vegas has spawned hordes of grasshoppers so large, they're showing up on the weather radar.In viewing the radar, CNN meteorologist Allison Chinchar said it looked like there were two storms over the Vegas area: one north of the city (that was actual rain) and another right over Las Vegas. But the second one wasn't moving as rain normally would, she said."It looked as though it should be torrentially downpouring in Las Vegas," said Chinchar.By changing the settings on the radar, meteorologists could see that the other "storm" was actually the massive hordes of grasshoppers that have settled over the city in recent days, Chinchar said. 673

After targeting keto and paleo dieters, Chipotle is courting vegetarians.The fast casual chain on Monday expanded its new line of diet-based bowls to include vegan and vegetarian options. "Lifestyle bowls" launched earlier this year with Whole30 and double protein meals in addition to the keto and paleo bowls.The lifestyle bowls are a way for Chipotle to market itself to a wide variety of customers focused on health, especially as it rebounds from E. coli and norovirus scares from a few years ago. And the vegetarian and vegan options could help raise awareness among an increasingly important customer base.Chipotle first introduced its vegan protein option, Sofritas, in 2014. Demand for Sofritas has continued to grow, the company said. Last year, it cooked 7.5 million pounds of Sofritas. Vegetarian and vegan meals made up roughly 12% of all the meals Chipotle sold in 2018."We've found that many people are increasingly looking for plant-based protein options," said Chris Brandt, Chipotle's chief marketing officer. The bowls don't include new vegan or vegetarian ingredients. They're only available as pre-configured options on Chipotle's website or mobile app.Taco Bell recently tried a similar tactic.In January, Taco Bell announced a plan to test out a vegetarian menu board that would highlight the restaurant's current vegetarian options, including tacos, tostadas burritos and crunchwraps. Putting all of the meat-free items on one menu should make it easier for vegetarians to see their options, Taco Bell explained. For Chipotle, the lifestyle bowls are a way not only to lure vegetarian eaters, but to create positive hype for the brand.During an earnings call in February, CEO Brian Niccol said that the lifestyle bowls "resonated with consumers in a big way." CFO John Hartung said the bowls "created an awful lot of buzz and interest.""The whole idea here is to really emphasize again that Chipotle can be an option for virtually any diet," said Sharon Zackfia, an analyst who covers restaurants for the research group of asset manager William Blair. By raising awareness of the many different diets Chipotle is compatible with, it is "eliminating the veto factor," she said.Chipotle has come a long way since it suffered following an E. coli outbreak that 60 Chipotle customers in 14 states ill in late 2015 and early 2016.Now, customers are coming back. In 2018, the company reported a revenue increase of 8.7% compared to the previous year. Sales at restaurants open at least a year jumped 4% in that time frame, and digital sales surged 42.4%.To help drive the rebound, Chipotle unrolled its "for real" marketing campaign, which highlights ingredients and offers transparency into its operations, streamlined its pickup options, expanded its delivery services and made its production lines more efficient, among other things. 2897

A tiny deer-like creature about the size of a rabbit has been photographed in the wild for the first time in three decades in southern Vietnam, delighting conservationists who feared the species was extinct.The silver-backed chevrotain, also called the Vietnamese mouse deer, was last recorded more than 25 years ago when a team of Vietnamese and Russian researchers obtained a dead chevrotain from a hunter."For so long, this species has seemingly only existed as part of our imagination," said Vietnamese biologist An Nguyen, an associate conservation scientist with Global Wildlife Conservation, a nongovernmental organization, and a PhD student with the Leibniz Institute for Zoo and Wildlife Research."Discovering that it is, indeed, still out there, is the first step in ensuring we don't lose it again, and we're moving quickly now to figure out how best to protect it," he said in a statement.Scientists had thought the tiny creature, which had been among 976
