The number of young Americans watching online videos every day has more than doubled, according to survey findings released Tuesday. They’re glued to them for nearly an hour a day, twice as long as they were four years ago.And often, the survey found, they’re seeing the videos on services such as YouTube that are supposedly off limits to children younger than age 13.“It really is the air they breathe,” said Michael Robb, senior director of research for 469

The National Hurricane Center said on Tuesday that it plans on sending a US Air Force reconnaissance aircraft on Wednesday as a storm system spins in the northern Gulf of Mexico. The National Hurricane Center said on Tuesday that the storm has a 70 percent chance of becoming a tropical depression or tropical storm by Thursday, and an 80 percent chance of becoming a depression or storm by the weekend. The center of the storm was located just off the Florida Gulf Coast. Regardless of the disturbance's status, it is still likely to bring heavy rain from the upper Texas coast to the Florida panhandle. The National Hurricane Center warns that the northern Gulf of Mexico has favorable conditions to form a tropical system. The next tropical storm in the Atlantic basin will be named Barry. The unnamed system is spinning in the same general area where Hurricane Michael gained strength last October. Hurricane Michael became a Category 5 hurricane just two days after becoming a hurricane. Hurricane Michael struck Florida, with the center coming on shore 20 miles east of Panama City. 1101

The creator of the Labradoodle cross-breed has said he inadvertently unleashed a "Frankenstein('s) monster."Wally Conron, 90, who worked for Guide Dogs Victoria in Australia when he bred the first Labrador-Poodle cross in 1989, spoke of his regrets at having begun a trend for designer breeds on an ABC podcast."I opened a Pandora's box and released a Frankenstein('s) monster," he said.His "big regret" is that his invention paved the way for "unethical, ruthless people" to breed the dogs without thinking of the health of their offspring.According to Conron, the majority of Labradoodles are "either crazy or have a hereditary problem," with healthy examples of the breed "few and far between."He believes that people have now gone too far with cross-breeding, which can increase a dog's risk of congenital disease, particularly down the generations. On the podcast, he laid particular scorn on the new Rottweiler-Poodle hybrid, known as a Rottle or a Rottie-Poo.Conron's original purpose in crossing a Labrador with a standard Poodle (which has a non-shedding coat) had been to provide a guide dog for a blind woman in Hawaii whose husband was allergic to dogs.The resulting litter of three was small, but one of the puppies did not trigger the husband's allergies and was sent to Hawaii to be her guide dog.As no one wanted the two remaining puppies, Conron asked the PR department at his work to spread the message of this new breed. Labradoodles quickly became popular in Australia and further afield.Now, designer breeds have become widespread -- but so has criticism of the consequences. Labradoodles, for example, can develop health problems common to Labrador Retrievers and Poodles such as hip dysplasia and eye disease.Colin Tennant, a British expert on dog behaviour with 45 years of experience in the industry, told CNN: "In essence, you are blindly breeding and altering genetics of the line without foreknowledge."Although Tennant said he doesn't have a problem with cross-breeding in general, he noted that breeders should pay more attention to dog's health.One example, he said, was the Bichon Frise, whose eyes water. "It must be in agony all the time," he explained. "They breed the face flat so they look humanoid because we find that attractive, with no consideration for the permutations we are producing with regards the dog's welfare or health." 2383

The number of foreign students coming to U.S. colleges and universities continued to fall last year, according to a new report, but the Trump administration says the drop should be blamed on high tuition costs and not students’ concerns over the nation’s political atmosphere.An annual report from the Institute of International Education found that the number of newly enrolled international students dipped by 1% in fall 2018 compared to the year before. It follows decreases of 7% and 3% in the previous two years, which were the first downturns in more than a decade.The downturn is a worry for universities that have come to rely on tuition from foreign students, who are typically charged higher rates. Some schools have blamed President Donald Trump’s rhetoric against immigrants for driving students away, but officials at the State Department, which pays for the annual report, dismissed the idea.Caroline Casagrande, deputy assistant secretary for academic programs at the department’s Bureau of Educational and Cultural Affairs, said students are deterred by the high cost to attend U.S. schools. She said the downturn is tied to students who were applying to college during the Obama administration, and that the numbers appear to be rebounding under Trump.“What we’ve seen today is a dramatically better picture compared to last year’s declines,” Casagrande said during a call with reporters. “The Trump administration has dedicated more resources than ever to international student mobility.”While fewer new students are coming, the study found that more are staying for professional training after they graduate. More than 220,000 were granted permission to stay for temporary work through a federal program, an increase of about 10% over fall 2017.China continued to send more students than any other country, followed by India and South Korea and Saudi Arabia. But booming years of growth from China have leveled off. The number of overall Chinese students in the country ticked up by less than 2%, and some campuses have seen major decreases in Chinese enrollment.The number of Chinese students at the University of Alabama has decreased by 43% over the past two years, to 266, according to the university’s annual enrollment report. At the University of Iowa and at Kansas State University, Chinese enrollment fell by about a third in that span.Declines from China have been attributed to several factors. Chinese students have reported difficulty getting U.S. visas amid a trade war between the two nations. Universities in Australia and Canada have worked harder to attract Chinese students. And some scholars say concerns over academic espionage have fueled anti-China sentiment on U.S. campuses.State Department officials said that they’re working to ease tensions and encourage Chinese students to study in the U.S. The department recently sent a delegation to China to promote academic exchange, and U.S. Ambassador Terry Branstad recently wrote an op-ed in a Chinese youth publication inviting students to study at U.S. schools.“The State Department has been working hard to make sure Chinese students know they’re welcome in the United States,” Casagrande said. “We want these Chinese students here.”The report also found that far fewer students are coming from Saudi Arabia, a shift that began in 2017 after the Gulf nation scaled back a scholarship program for global study. There were also dips in students coming from South Korea, Japan and Mexico.Meanwhile, the U.S. attracted growing numbers of students from Asia, Latin America and Africa. Numbers from Brazil and Bangladesh jumped 10% last year, the report found, while Nigeria ticked up 6%. Many universities have shifted their recruiting efforts to those areas in recent years as they look to offset losses from China.“More institutions are expanding their outreach in more regions,” said Mirka Martel, the head of research, evaluation and learning at the Institute of International Education, which is based in New York. “This growth demonstrates how attractive a U.S. education is for students around the world.”The academic subjects students come to study are also starting to shift. The number of students studying business, an area that has long been a draw for Chinese students, fell by 7% last year, the report found. Meanwhile, math and computer science saw a 9% increase and surpassed business as the No. 2 subject behind engineering.While the report focuses on data from 2018, it also included early findings for this year. Among more than 500 schools surveyed, the number of newly enrolled foreign students fell by 1% again, while the number of total international students fell by about 2%.___Collin Binkley can be reached on Twitter at 4748

The Federal Bureau of Investigation has quietly been searching for private contractors who could gather and feed to law enforcement tremendous amounts of user data straight from social media platforms such as Twitter, Facebook and Instagram.The U.S. government needs "real-time access to a full range of social media exchanges" to better fight terrorist groups and domestic threats, the FBI said in its 415
