The ability to regrow their tails has been a documented and life-saving skill of small reptiles like lizards and geckos. Now, researchers say they have details of larger reptiles, alligators, regrowing their tail.A team of scientists from Arizona State University and the Louisiana Department of Wildlife and Fisheries were surprised to discover the alligators have the ability to regrow their tails up to 9 inches. Their report was recently published in Scientific Reports.“Overall, this study of wild-caught, juvenile American alligator tails identifies a distinct pattern of wound repair in mammals while exhibiting features in common with regeneration in lepidosaurs and amphibia,” the researchers concluded.The wild-caught alligators most likely lost their tails by traumatic injury, the scientists stated. The team also had samples of regrown tails from alligators who had died."The regrown skeleton was surrounded by connective tissue and skin but lacked any skeletal muscle (which lizard tails do regenerate with)," Kenro Kusumi, co-senior study author and professor and director of ASU's School of Life Sciences and associate dean in the College of Liberal Arts and Sciences, told CNN.Even without muscles, a regrown tail is important for alligators’ survival.The team hopes their research will help scientists working on regenerative therapies in humans. Although humans are incapable of regrowing a limb, researchers said we have the same cells and pathways that alligators and other animals use for regeneration. 1532

Technology is constantly evolving, and often times, it makes things more convenient.Charley Sullivan uses smart technology a lot, specifically her Amazon Echo.The Echo’s virtual assistant, Alexa, will read Charley’s emails aloud to her, check the weather and more.She thought it’d be a great gift for her husband, Bobby, but he knew she’d enjoy it more.“I knew how much she was going to use that thing,” he says. “I mean, she uses it to read her bible listened to radio programs; she plays games on it.” Amazon’s Alexa has brought convenience to homes everywhere, by playing music, checking the news, ordering groceries and more. But it’s especially helpful when you can't see.Both Charley and Bobby are blind.“Well, it's so wonderful,” Charley says of the device. “And when I was a child, we had braille, and we had books on records.”Now, the two are using Alexa, along cell phones and an Apple watch to make life easier.While they wish the technology could do even more, the two are grateful.“If you are going to be blind, this is the time, the day and time to be blind, with all the technology that there is out there today,” Charley says. 1155

Tax refunds, a lifeline for many Americans to help get caught up on bills, or to buy much-needed items, could once again take some time to reach Americans in 2021.Earlier this year, many tax payers complained about delayed refunds amid the early days of the coronavirus pandemic. The IRS sent many of its employees to work from home, resulting in delays in processing refunds. It was also difficult for many Americans to contact the IRS.Meanwhile, the IRS was processing millions of economic impact payments as most American adults were eligible to receive a ,200 payment from the federal government.The IRS advised tax payers on Tuesday to not rely on a tax refund coming by a certain date.“The IRS always cautions taxpayers not to rely on receiving a refund by a certain date, especially when making major purchases or paying bills,” the IRS said on Tuesday. “Some returns may require additional review and processing may take longer. For example, the IRS, along with its partners in the tax industry, continue to strengthen security reviews to help protect against identity theft and refund fraud. Just like last year, refunds for tax returns claiming the Earned Income Tax Credit or Additional Child Tax Credit [lnks.gd], cannot be issued before mid-February. This applies to the entire refund, even the portion not associated with these credits.”The IRS said that the fastest way for tax payers to obtain a refund is to file electronically and request payment via direct deposit.The IRS said that once a tax return is received, Americans can track their refund using the “Where’s My Refund” tool on its website.According to the IRS, the agency issued 122 million refunds for tax year 2019, totaling 2 billion. The average refund was ,704. All told, the IRS processed 253 million tax returns for last year. 1825

Taylor Swift was once the sweetheart of Nashville and a frequent attendee of the CMA Awards.She racked up 11 wins and 26 nominations before crossing over to becoming a global pop star. Since that time she has moved away from her country roots. In fact, she has not seen a CMA nominee since 2014 when she was nominated for Female Vocalist of the Year. She is back on the CMA ballot this year not as a performer but as a songwriter. She wrote Little Big Town's chart-climber "Better Man", which is up for Single of the Year, Song of the Year and featured on a nomination for Album of the Year.Little Big Town is also nominated for Vocal Group of the Year. The Song of the Year nomination is what has Music Row talking about whether they will see Swift at this year's award show. That particular award is given to the writer of the song, not the performer.That means if the song is a winner tonight at Bridgestone Arena it would make sense to see Swift on stage to accept the award.Her last appearance at the show was just a year ago for the 50th anniversary when she presented Garth Brooks with the award for Entertainer of the Year.?Swift is in the middle of a busy week. In the past 24 hours she released the full track list for her upcoming album and also shared videos from a private listening party she had for lucky listeners at home.Swift's new album, "Reputation" drops Friday.To find out if she will make an appearance at the 51st Annual CMA Awards, tune in tonight at 7p.m. (CT) on ABC.  1518
