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

The 2016 election was psychologically traumatic for some, according to a new study published in the Journal of American College Health. It found that 1 out of 4 students surveyed experienced clinically significant event-related distress short term.Researchers from San Francisco State University, University of California, San Francisco and Arizona State University assessed a diverse group of nearly 800 undergraduates at Arizona State two to three months after the election.A key battleground, Arizona got a lot of political attention. Ultimately, Trump won Arizona by a narrow margin, earning 48.7% of the vote.The survey students filled out asked questions to determine the emotional effect of the event the election. It asked about the impact the election had on close relationships and assessed clinical symptoms of distress and subclinical impacts, meaning emotions that don't present definitive, more readily observable symptoms.Symptoms included "avoidance," a clinical term used to describe how someone deliberately stays away from whatever is causing them trauma, and "intrusion," a clinical term meaning the inability to keep memories of the source of their trauma from returning. The researchers also looked to see if demographics made a difference.Most of those surveyed, 65%, said the election had no impact on their close relationships. About 24% reported a slight or very negative impact and a little more than 10% reported a positive impact.If the election did have a negative emotional impact, avoidance was more common than intrusion among these students. One-fourth of participants showed clinically significant avoidance and intrusion symptoms in response to the election. Women, Democrats, people who did not identify as Christian and sexual minorities reported significantly more event-related distress, the study found.The students surveyed came from diverse backgrounds and held a mix of political opinions. Of the group, 18.5% reported that they were satisfied with the result of the election, 25% said they were somewhat satisfied, 19.2% said they were somewhat dissatisfied, and 37.2% said they were completely dissatisfied. Thirty-nine percent also reported that they were "considerably or extremely" upset by the election, 28.5% were not at all upset, the rest fell somewhere between.The study had limitations. The survey did not look at conditions long term. It couldn't rule out other stressors. It only looked at this one election and did not evaluate how students reacted in other years.Other studies looking at the 2016 election have found similar results. A study released in June that surveyed nearly 300 students two days before the 2016 election, on election night, and two days after, found that students who were concerned about Trump's ability to govern and those who were a part of the "non-dominant social group," including women and people of color, showed increased signs of stress before and during election night. Biological tests showed some signs of increased stress after the election, although there was a general recovery in mood, according to self-reported results.Lindsay Till Hoyt, who co-authored that study and is not connected with the current work, found this latest research interesting. She was not surprised that students felt increased stress."I think so much of the social media and news about the election really felt personal and aimed at specific groups like Mexican Americans and women," Hoyt, an?assistant professor of psychology at Fordham University,?said.For example, she cites Trump's justification for building a wall between Mexico and the US, saying in a debate "we have some bad hombres here and we're going to get them out." Or when a 2005 "Access Hollywood" tape was released in which Trump talked about how his celebrity status allowed him to behave aggressively with women, saying he could "grab them by the (expletive)" and that he would sometimes "just start kissing them.""Comments like those could hit very close to home, as opposed to arguments about abstract concepts like foreign policy and economic policy, students might not be as well versed in those topics," Hoyt said. "Because there was literal name-calling going on in the election cycle, even with students less politically engaged, that strong language and the harsher crassness of the rhetoric may have had a more broad effect on these students."In another study she and a graduate student are working on, they've noticed that both sides, conservatives and liberals, say they have felt discriminated against during the election, and preliminary results show it has caused them stress that interrupted their sleep."It's not just along ethnic and racial discrimination lines," Hoyt said "Conservatives also feel discrimination is affecting their sleep, it crosses both sides of the political aisle."Another 2018 study looking at how 700 teachers navigated the days after the election with K-12 students, and researchers found stories of such distress. One surveyed teacher remarked "for millions of people, this is real trauma."Beth Sondel,?who co-authored that study of teachers, finds this latest research on college students useful."Many of these young kids that the teachers were talking about in our study weren't privy to the policy being presented in the election, but the rhetoric was so strong it was impacting them," said Sondel, a research assistant professor in the department of instruction and learning at the University of Pittsburgh School of Education.Teachers reported they saw an immediate heightened fear of deportation among students. One teacher reported one of her seventh graders asked her if "Trump can come with a bus and get me?" Another teacher in Nebraska said a high school student who was expecting a baby asked if the teacher would take care of the baby if he was deported. Another teacher reported consoling a second-grade student who told her through tears that she was worried that when she'd get home from school her parents wouldn't be there."In general, I think our results are similar, in that we are finding that even these younger students are internalizing this rhetoric and it is causing stress and trauma," Sondel said. "I think the personal has become really political in this election."The authors hope this latest study will help mental health professionals better counsel college students have. Knowing that an election can cause distress, professionals should ask about it to better target treatment, they said. 6606

The Australian refugee deal that US President Donald Trump once derided as "stupid" and "horrible" is happening.The first group of refugees being held at Australian offshore detention centers on Nauru and Papua New Guinea's Manus Island will leave for the US in the "coming weeks," the Australian government has confirmed in a statement."There will be about 25 (refugees) from both Manus and Nauru, will be going to the United States and I just want to thank again President Trump for continuing with that arrangement," Australian Prime Minister Malcolm Turnbull?said in an interview with CNN's Australia affiliate Seven News.Under the terms of the arrangement, refugees selected by the Australian authorities for resettlement in the US are not guaranteed entry into the country. They must first pass a strict vetting process -- which can take months.An official at the US State Department told CNN on Wednesday that to date, they have determined one individual meets resettlement requirements and will be moved in "the coming weeks." The official said he expects the first batch of approved refugees to be notified within days."We expect refugees to travel to the United States in the coming weeks," the official said.Trump made it clear to Turnbull he was not a fan of the deal during their first phone call following Trump's inauguration in January, details of which were later revealed in a?leaked transcript?published by the Washington Post in August."I am the world's greatest person that does not want to let people into the country. And now I am agreeing to take 2,000 people and I agree I can vet them, but that puts me in a bad position. It makes me look so bad and I have only been here a week," Trump said."This is a big deal," Turnbull responded. "It is really, really important to us that we maintain it. It does not oblige you to take one person that you do not want.""This is a stupid deal. This deal will make me look terrible," Trump said, adding later "I think it is a horrible deal, a disgusting deal that I would have never made."The deal was negotiated by former US President Barack Obama and involved the transfer of 1,250 refugees from Australia in exchange for a group of Central American refugees from camps in Costa Rica.Towards the end of their phone call, Trump appeared to concede that he would stick with the deal, but he said he would tell the American people that "I hate it." 2432

The American Academy of Pediatrics said 61,000 children in the United States tested positive for COVID-19 last week.The medical professionals said the new child cases reported is the highest weekly figure since the pandemic began. The cases were reported in a one-week period that ended Oct. 29.The organization said that since the pandemic began up to Oct. 29, more than 853,000 children tested positive for the coronavirus. During October, nearly 200,000 new cases in children were reported by state health departments, who track the data"This is a stark reminder of the impact this pandemic is having on everyone – including our children and adolescents," said AAP President Sally Goza, MD, FAAP said in a press release. "This virus is highly contagious, and as we see spikes in many communities, children are more likely to be infected, too. We can help protect everyone in our communities by keeping our physical distance, wearing masks, and following other recommendations from our doctors and public health experts."The AAP said it believes the number of children with COVID-19 is higher because children's symptoms are often mild, and medical professionals may not test them for every illness." 1210
