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

New Mexico Democrat Deb Haaland and Kansas Democrat Sharice Davids became the first Native American women elected to Congress this week.Davids identifies as a lesbian, making her the first openly LGBT member of Congress from Kansas. She will enter Congress as a lawyer and a former mixed martial arts fighter.They are not alone in creating history: the first Muslim women, Rashida Tlaib (a Michigan Democrat) and Ilhan Omar (a Minnesota Democrat) were also elected to US Congress. Tlaib is endorsed by the Democratic Socialists of America, a burgeoning left-wing group that also counts New York Democratic congressional nominee Alexandria Ocasio-Cortez among its members.Omar, in addition to being one of the first Muslim women in Congress, will also be the first Somali-American member. She came to the US more than two decades ago as a refugee. Tlaib actually campaigned with Omar ahead of the latter's primary race earlier this year.In Colorado, Democratic US Rep. Jared Polis will be the state's next governor, becoming the nation's first openly gay man elected to a governor's mansion.During his gubernatorial bid, Polis has pushed for universal health care, free early childhood education and progressing Colorado to a 100% renewable energy state.This election also saw an age record set: New York Democratic congressional nominee Alexandria Ocasio-Cortez won her general election race easily and became the youngest woman ever in Congress.Having turned 29 last month, Ocasio-Cortez inched out the previous holder of the distinction, New York Democratic Rep. Elise Stefanik, who was elected to Congress at age 30.  1673

New research has found American workers took an average of 17.2 days of vacation in 2017, up almost a half-day from 2016.Project: Time Off, who are affiliated with the U.S. Travel Association, says "this marks the highest level for American vacation usage since 2010 (17.5 days) and more than a full-day increase since bottoming out at 16 days in 2014."But maybe these aren't enough days as 52 percent of Americans left an "accumulated 705 million unused days" in 2017, which has increased from 662 million in 2016.How? The increase in unused days, despite Americans taking more vacation, is attributed to employees earning more time off (23.2 days in 2017, compared to 22.6 in 2016).Further, nearly 25 percent of Americans have not taken a vacation in more than a year.Some possible barriers?  807

New video appears to show workers for Caltrans handing out campaign materials defending the state's recent gas tax increase while on the job. The video, shot Tuesday, was released by the Yes on 6 campaign, which is pushing to repeal the recent 12-cent-per-gallon hike on the November ballot. The video shows Yes on 6 campaign manager Matt Stockton in the drivers seat of a car. He is apparently stopped at a Caltrans contractor's site along the 78 near Ramona. The video shows a man in a hard hat approaching the window, handing Stockton what appears to be a No on 6 campaign flier defending the gas-tax increase.Stockton in the video asks the man if he is with Caltrans, and the man answers that yes, his crew is working with Caltrans. Other images released by the campaign appear to show the workers were with Pico Rivera-based Manhole Adjusting Inc., and that a Caltrans supervisor was on site. "The misuse, the abuse of taxpayer funds being used in a political campaign, it is shameful, it is outrageous, and it needs to stop right now," said Carl DeMaio, who is chair of the Yes on 6 campaign. Caltrans, a state agency, said in a statement that it is looking into the matter, and has contacted its contractors to say it does not condone political advocacy on project sites. The No on 6 campaign, fighting to keep the gas tax increase, says it was unaware of the incident and that it denounces any inappropriate use of public resources or venues for campaign purposes."The No on 6 campaign very carefully follows all rules prohibiting the use of public resources for campaigning and often reinforces those rules to anyone involved with the campaign," the campaign said in a statement. Calls to the on-site Caltrans supervisor and Manhole Adjusting Inc were not immediately returned."If this is happening on more than one occasion, it's egregious," said Seth Kaplowitz, a finance lecturer at San Diego State University. "It's egregious because they know they're not supposed to be doing it."Last year, Gov. Jerry Brown and the state legislature raised the gas tax by 12 cents-per-gallon with future increases planned. Already, the state says more than 0 million have poured into San Diego to fix county roads and highways. The measure to repeal the tax increase will be on the November ballot.  2378

NEW YORK (AP) — This year’s Black Friday was the biggest ever for online sales, as fewer people hit the stores and shoppers rang up .4 billion in transactions from their phones, computers and tablets.That’s just behind the .9 billion haul of last year’s Cyber Monday, which holds the one-day record for online sales, according to Adobe Analytics. Adobe measures sales at 80 of the top 100 U.S. online retailers.Adobe expects online sales to jump to another record this Cyber Monday with an estimated total of .4 billion. Much of the shopping is happening on people’s phones, which accounted for 39% of all online sales Friday and 61% of online traffic.Shoppers have been looking for “Frozen 2” toys in particular. Other top purchases included sports video games and Apple laptops.All the online shopping may have helped thin the crowd at malls on Black Friday.Traffic at stores fell 2.1% on Black Friday from a year ago, according to preliminary figures from RetailNext. It tracks in-store activity at tens of thousands of locations, including specialty apparel retailers, big-box stores and mall-based stores. The drop in traffic helped lead to a 1.6% dip in sales.Online and in-store shopping aren’t always completely separate, though. Many people buy things online, only to head to the store to pick them up. Such sales surged 43.2% on Black Friday from a year ago, according to Adobe.This holiday shopping season may be the most harried in years because it’s the shortest since 2013. Thanksgiving this year fell on the last Thursday in November — the latest possible date it could be.Much is riding on the success of the holiday season’s sales. The U.S. economy is still growing steadily, but gains have slowed since its sizzling start to the year. Economists say strong spending by households is helping to bolster growth and make up for weak confidence among businesses given all the uncertainties about the U.S.-China trade war and other factors. 1967
