New research may be hard for some dog owners to accept; the study found that dogs do not understand every word a human says to them.The researchers say dogs cannot hear subtle differences between words the way humans can. For example, the difference between “dog” and “dig” sounds different to human ears, but not so different to dog ears.The researchers came to their conclusion after measuring brain activity of family dogs by taping electrodes to the animals’ heads. They then played recordings of instruction words they knew, like “sit,” then similar-sounding nonsense words, like “sut,” and finally an unrelated nonsense word or sound, like “bep.”The dogs in the study, who were not trained ahead of the study, could quickly tell the difference between the instruction words and the unrelated nonsense words."The brain activity is different when they listen to the instructions, which they know, and to the very different nonsense words, which means that dogs recognize these words," lead study author and postdoctoral researcher at E?tv?s Loránd University in Budapest, Lilla Magyari told CNN.So, the good news is, yes, dogs are listening to human words and understanding some.However, brain activity showed a similar reaction in the dogs between the instruction word and the similar nonsense word.Dogs are renowned for their auditory capacity and ability to hear words and sounds, however the results show they may not be able to distinguish between subtle speech sound differences.Magyari says more research is needed to understand why this is."They may just not realize that all details, the speech sounds, are really important in human speech. If you think of a normal dog: That dog is able to learn only a few instructions in its life," she told CNN.The study was published this week in the Royal Society Open Science journal. 1845

News helicopters in Philadelphia captured demonstrations turning into lawlessness as several people were seen breaking into businesses Tuesday evening.Philadelphia Police said that a crowd of approximately 1,000 people were looting a business in Philadelphia on Tuesday.The unrest began on Monday after Walter Wallace Jr., a 27-year-old Black man, was shot and killed by officers in Philadelphia. Spokesperson Tanya Little of the Philadelphia Police said that Wallace was ordered to drop a knife before being shot by officers.The incident was captured on video from a bystander, and Little confirmed that two of the officers were wearing body worn cameras. Whether that video will be publicly released will be determined in the coming days.Video of the incident showed officers pointing a weapon at Wallace. After trying to back away from Wallace, officers then fired at him.Police Commissioner Danielle Outlaw said that a full investigation of what transpired is underway.Shaka Johnson, an attorney representing the Wallace family, told the Inquirer that family called for an ambulance and not officers. Johnson said that Wallace's pregnant wife told officers that Wallace had a bipolar condition. 1206

NEW YORK (AP) — A new federal report shows vaping rates among U.S. teenagers fell dramatically this year.The drop comes in the wake of last year's outbreak of vaping-related illnesses and deaths.The national survey found that just under 20% of high school students and 5% of middle schools students were recent users of electronic cigarettes and other vaping products.That marks a big decline from a similar survey last year that found about 28% of high school students and about 11% of middle school students recently vaped. That's a decline of about 1.8 million teens total.The survey was done by the U.S. Food and Drug Administration and Centers for Disease Control and Prevention. They looked at survey data from middle school and high school students, grades 6-12.Despite the progress in lowering the number of teens using e-cigarettes, there are 3.6 million youth who currently use them. Of those, almost 83% use flavored e-cigarettes or vaping products.In addition to the survey, the FDA announced their premarket review requirement of tobacco products to ensure they go through a “robust scientific evaluation” before hitting store shelves. 1156

NEW YORK — An influential scientific panel on Tuesday voted to recommend to the CDC that when a COVID-19 vaccine becomes available, both front line health care workers and residents in long-term care facilities should be prioritized first. The Advisory Committee on Immunization Practices voted 14-1 in favor of adopting the following recommendation: When a COVID-19 vaccine is authorized by FDA and recommended by ACIP, vaccination in the initial phase of the COVID-19 vaccination program (Phase 1a) should be offered to both 1) health care personnel and 2) residents of long-term care facilities.Watch the meeting live here."About one (American) dies every minute from COVID-19. During this ACIP meeting, about 120 people will die," Dr. Beth Bell said during initial remarks at the beginning of the virtual meeting Tuesday.The ACIP met Tuesday afternoon in an open-to-the-public, virtual meeting to vote on the proposal that gives priority to health care workers and patients in nursing homes and other long-term care facilities. The two groups together represent around 23 million Americans out of a population of about 330 million; about 21 million in health care professions and less than 3 million adults living in long-term care facilities.Current estimates project around 40 million doses combined available by the end of 2020. And each vaccine product requires two doses.The CDC said Tuesday they expect 5-to-10 million doses available each week after a vaccine is authorized by the FDA. They say these numbers necessitate the need for sub-group prioritizing, since not all health care workers or long-term care facilities can be vaccinated at once. Another consideration the panel discussed is not having an entire unit or group get vaccinated at once; if there are side effects like fatigue or other symptoms that necessitates taking a day or two off, this could leave a unit critically short-staffed. During Tuesday's presentation, Dr. Kathleen Dooling talked about statistics from COVID-19 patients in the US and how it lead to health care workers and long-term facility staff and patients to be at the top of the vaccine list. Long-term care facilities are responsible for six percent of COVID-19 cases and 40 percent of COVID-19 deaths in this country, she said. Later this month, the Food and Drug Administration will consider approval of two vaccines made by Pfizer and Moderna. The panel meeting Tuesday said they hope to learn more about the safety and effectiveness of the vaccines as more information is released by the FDA.Dr. Dooling said one of the questions they hope to ask about the Phase 3 trial data of both Pfizer and Moderna is how effective one dose of the vaccine has shown to be. They will also be taking a deeper look at the age groups of those included in the trial, and the efficacy of the vaccines on older people. Some of the comments during the public comment section referenced the lack of transparency released at this time about the vaccines and the panel trying to make vaccination decisions without it. However, the panel, while voting, expressed faith in the FDA's process of approving the vaccine as safe for all Americans. Once vaccines are given, the CDC and FDA will be asking all health care providers and facilities to use the existing Vaccine Adverse Event Reporting System, VAERS, to monitor any side effects and adverse reactions to the COVID-19 vaccines. The advisory panel will meet again at some point to decide who should be next in line. Among the possibilities: teachers, police, firefighters and workers in other essential fields such as food production and transportation; the elderly; and people with underlying medical conditions.Experts say the vaccine will probably not become widely available in the U.S. until the spring.ACIP is a 15-member panel of outside scientific experts, created in 1964, that makes recommendations to the director of the Centers for Disease Control and Prevention, who almost always approves them. Childhood vaccine schedules are one example of the work of this group. The recommendations are not binding, but for decades they have been widely heeded by doctors, and they have determined the scope and funding of U.S. vaccination programs.It will be up to state authorities whether to follow the guidance. It will also be left to them to make further, more detailed decisions if necessary — for example, whether to put emergency room doctors and nurses ahead of other health care workers if vaccine supplies are low. 4517

Neighborhoods all across America are at a crossroads by figuring out how to grow and develop, without abandoning the people who made the communities so great in the first place.One group of women in Atlanta are facing that exact problem. They're putting up a fight against a new development, and they say we can all stake a stand for what we believe.Michelle Schreiner and Princess Wilson are two of the women who live in Atlanta's Old Fourth Ward neighborhood. It's a neighborhood Wilson has seen change before her eyes.“When I was growing up, it was a predominantly African-American neighborhood,” Wilson says. “It was a black neighborhood, and everybody knew everybody there lived here.But when a developer announced plans for a new condo building, the women said enough was enough. The developer’s original plan was to build a 21-story property with 16 luxury condos, selling for million each. 908
