NEW YORK (AP) — Health experts are hoping Joe Biden’s administration will put in place something Donald Trump has not — a comprehensive national testing strategy. They say such a strategy could systematically check more people for infections and spot surges before they take off. The health experts say it would be an improvement from the current practice. Some experts say the lack of such a system is one reason for the current national explosion in cases, hospitalizations and deaths. There are differing opinions on what a national testing strategy should look like. But many experts say rapid and at-home tests should be used so Americans can check themselves and stay away from others if they test positive. 721

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

Then I slammed into the ground.”MAP: Track crime happening in your neighborhoodHer service dog, Justice, was on the other side of her and made it away uninjured.Michaels said she didn’t break any bones, but along with scrapes and bruises, she has a lingering pain in her left shoulder.That has compounded problems from previous shoulder and arm injuries and has made it nearly impossible for her to lift herself into her car, which has been modified for her to drive without foot pedals but does not have a ramp or lift.She has been trying to raise funds to buy a van with a wheelchair lift for more than a year, but the need has become more urgent.“I have to,” she said of buying a van, “if I want to keep my independence.”Her GoFundMe page can be found here. 1178
