As of Tuesday, Petco says they no longer sell electronic "shock" collars and have removed them from its shelves and website.The company said they stopped selling the human- and bark-activated electronic pet collars in a press release on Tuesday because they wanted to strengthen their commitment to positive reinforcement training methods. They also wanted to solidify their evolution from "a leading pet specialty retailer to a category-defining health and wellness partner" for animals and their owners."Electricity may be critical to powering your microwave, but it has no role for the average pet parent training their dog," said Petco CEO Ron Coughlin in the press release. "Shock collars have been shown to increase fear, anxiety, and stress in dogs, and we believe there's a better way – Positive Reinforcement Training."The San Diego-based company is also calling on the pet industry and consumers to join in its newly launched "Stop the Shock" online campaign that will create "responsible regulation for the retail sale of shock collars to general consumers."Along with today's announcement, Petco also launched a new look declaring itself "Petco, The Health + Wellness Co." to reflect how they've evolved into a health and wellness company."As a health and wellness company, our mission is focused on improving pet lives, and we think selling shock collars does the opposite," Coughlin said in the news release. "It's our responsibility to ensure that we, and others, aren't putting potentially harmful products in the wrong hands." 1551

Attorneys for Maria Butina and the Justice Department gave more signs Thursday morning they are negotiating a plea deal for the accused Russian spy.In a conference call with a federal judge in Washington, the attorneys said another upcoming hearing in the case should be canceled and that subpoenas planned for American University, where Butina was a graduate student, may be withdrawn by the end of this week.Both prosecutors and defense attorneys have previously indicated they were negotiating to end Butina's case.Butina was charged this summer for illegally acting as a foreign agent for Russia and accused of trying to create a back channel for Russia through activist groups, including the National Rifle Association.She is currently being held in solitary confinement at a Northern Virginia jail, her attorneys have said. So far, she has maintained her innocence, saying she was never a foreign agent and simply a foreign student studying in America.If Butina were to change her plea in the case from not guilty to guilty, she would likely return to Russia.Prosecutors previously told a court she was in touch with Russian backers and agents as she ingratiated herself with politically powerful Americans.The-CNN-Wire 1233

ATLANTA, Ga. – The U.S. Marshals Service says it found 39 missing children in Georgia this month during an investigation called “Operation Not Forgotten.”The two-week operation in Atlanta and Macon resulted in the rescue of 26 children, the safe location of 13 kids and the arrest of nine “criminal associates,” the USMS announced Thursday.Additionally, investigators say they cleared 26 arrest warrants and filed additional charges for alleged crimes related to sex trafficking, parental kidnapping, registered sex offender violations, drugs and weapons possession, and custodial interference.The USMS says the missing children were considered to be some of the most at-risk and challenging recovery cases in the area, based on indications of high-risk factors such as victimization of child sex trafficking, child exploitation, sexual abuse, physical abuse, and medical or mental health conditions.Since its partnership with the National Center for Missing and Exploited Children, the USMS says it has recovered more than 1,800 missing children.“When we track down fugitives, it’s a good feeling to know that we're putting the bad guy behind bars. But that sense of accomplishment is nothing compared to finding a missing child," said Darby Kirby, Chief of the Missing Child Unit. “It's hard to put into words what we feel when we rescue a missing child, but I can tell you that this operation has impacted every single one of us out here. We are working to protect them and get them the help they need.”This month’s operation was the culmination of several months of planning and coordination between the USMS, NCMEC, Georgia Bureau of Investigation, Georgia Office of the Attorney General, Georgia Department of Family and Children Services, Georgia Department of Juvenile Justice, the Federal Bureau of Investigation and Children’s Healthcare of Atlanta.“The U.S. Marshals Service is fully committed to assisting federal, state, and local agencies with locating and recovering endangered missing children, in addition to their primary fugitive apprehension mission,” said Director of the Marshals Service Donald Washington. “The message to missing children and their families is that we will never stop looking for you.” 2233

  

As more and more public spaces open back up, many people are finding themselves a little jumpy when they hear someone cough nearby. Are they sick, is it allergies, is it coronavirus?Chances are, we are jumping to conclusions about those “sick” sounds we find disgusting, according to a recently published study from the University of Michigan and University of California, Irvine.“We find no evidence that perceivers can reliably detect pathogen threats from cough and sneeze sounds, even though they are reasonably certain they can,” said Nicholas Michalak, the study’s lead author and a University of Michigan psychology graduate student.In other words, we humans are not very good at distinguishing the seriousness of a cough or sniffle by the sound of it. In fact, the study found that the more disgusting a person perceived the sound to be, the more likely they were to believe the sound came from an infected person, regardless of whether it did.Previous research has indicated people can accurately diagnose infection in others using other senses, like sight and smell.The research is based on four studies that had participants judge whether a cough or sneeze sound came from people infected with a communicable (easily spread) disease or not. On average, participants guessed four out of ten sounds correctly.“Moreover, there was no evidence that accuracy improved when participants knew the true number of infectious sounds in advance or when participants focused on how clear or disgusting they perceived the sounds,” Michalak said. “Despite this poor overall accuracy, perceivers consistently reported reasonable certainty in their judgments.”The study’s authors theorized that people have a belief that a sound that disgusts them is likely to represent a disease threat - this could lead them to exhibit biases to avoid interactions with others who make disgusting but noninfectious noises, according to Mickalak.The study’s co-authors are Oliver Sng, assistant professor of psychological science at UC-Irvine, and U-M graduate student Iris Wang and U-M associate professor of psychology Joshua Ackerman.Read the full study here. 2150

  

As novel coronavirus cases soar across the country, states are struggling to keep up with the demand for testing. Some states are reporting big backlogs and difficulty getting tests.“We need to actually continue doing a bunch of work in America to figure out additional approaches to do testing,” said Dr. Bob Kocher.Dr. Kocher is the former co-chair of California's Testing Task Force. The state formed the team back in March to figure out how to get everyone tested. Back then, they were struggling to do 2,000 tests a day. Now, they're doing more than 100,000 a day.“California, and most states, had giant shortages of the world’s most expensive Q-tips, called swabs, that you need to collect the samples and the people who make them couldn’t make more of them,” Dr. Kocher explained. “We worked with companies to 3-D print them and to source those from other places in the world and buy them and bring them to California.”They worked to find labs that could do high-capacity testing and expanded the number of testing sites. But as cases increased across the state and nation, five months into the pandemic, testing turnaround time is an issue.“It’s something I’m concerned about as demand for testing grows everywhere in the country and on the earth, the labs are going to sporadically have backlogs, and over time, they could have backlogs because it’s hard to make more supply of the test,” Dr. Kocher said.Dr. Kocher says it depends on where the test is sent. Some labs have backlogs and it’s a logistics issue. If the lab your test site is using is in another part of the country, it'll likely take longer to get results.In a statement, Quest Diagnostics said, "We are grappling with surging demand that is outpacing capacity. This is due to surging cases of COVID-19 across much of the United States, particularly the West, Southwest and South. We have a prioritization program to help direct testing to patients most in need. Our turnaround time for priority one patients is 1 day on average."In a recent press conference, California's Health and Human Services Agency Secretary Dr. Mark Ghaly said supply chain challenges forced the state to prioritize who gets tested first.“Surges across the nation have created challenges of getting tests processed, not just collected, and ensuring our guidelines not only say who needs to be tested but give guidance to labs on which specimens to process first,” Dr. Kocher said.Right now, priority means those who are hospitalized, healthcare workers, first responders, social service employees, those who are 65 and older and those with chronic medical conditions. But, we simply need more tests.“The challenge with COVID-19 is that each person infects two, three more people and that leads to exponential growth of people who are infected and exponential growth in demand for testing,” Dr. Kocher said. “The companies who manufacture tests have been extraordinary scaling up their capacity to manufacture tests they can grow them by 10, 30 maybe a 100 percent, but the demand for COVID testing is growing 1,000 percent.”The American Clinical Laboratory Association which represents Quest and other labs released a statement saying many labs are getting more test orders than they're able to process in a single day.In a statement, the company said, "We can’t do it alone. Laboratories, diagnostic manufacturers, ordering providers, public health officials, states and importantly, the federal government – including Congress and the Administration – all have a role to play in addressing the challenges hampering our nation’s response to this public health crisis."The test, Dr. Kocher says, only tells you if you're infectious at the time you were tested. It's yet another hurdle for states to tackle."So, we need to figure out what is the mechanism to test people at the right frequency to make us all safe and fell confident in going to work, school, nursing home or being an essential worker,” he said. “It’s really important.”Figuring out what that looks like means looking at new technologies, getting the government involved and working on our manufacturing sector so we have more tests and fewer logistical problems as we consistently try to keep up with the virus that seems to be one step ahead of us all. 4276
