The days of passengers bringing rabbits, turtles and birds on planes as emotional-support animals could be ending. The U.S. Department of Transportation on Wednesday proposed that only specially trained dogs qualify as service animals, which must be allowed in the cabin at no charge.Airlines could let passengers bring other animals on board, but hefty fees would apply. Airlines have complained that some passengers try to get their pets on board for free by claiming they need them for emotional support under the current rules. 543

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 2019 Nobel Prize for Medicine has been jointly awarded to William Kaelin Jr., Sir Peter Ratcliffe and Gregg Semenza for their pioneering research into how human cells respond to changing oxygen levels.Announcing the prize at the Karolinska Institute in Stockholm on Monday, the Nobel committee said that the trio's discoveries have paved the way for "promising new strategies to fight anaemia, cancer and many other diseases."The 2019 medicine laureates, the committee added, have identified molecular machinery that regulates the activity of genes in response to varying levels of oxygen.The importance of oxygen has long been established, the committee explained, but how cells adapt to changes in its levels remained unknown.Randall Johnson, prize committee member, described the trio's work as a "textbook discovery.""This is something basic biology students will be learning about when they study, at aged 12 or 13, or younger, biology and learn the fundamental ways cells work. This is a basic aspect of how a cell works and, from that standpoint alone, it's a very exciting thing."The winnersNew York-born Kaelin established his own research laboratory at the Dana-Farber Cancer Institute in Boston and became a full professor at Harvard Medical School in 2002.Semenza, also born in New York, became a full-time professor at Johns Hopkins University in 1999 and since 2003 has been the Director of the Vascular Research Program at the Johns Hopkins Institute for Cell Engineering.Ratcliffe, who was born in Lancashire, England, studied medicine at Cambridge University and established an independent research group at Oxford University, becoming a full professor in 1996. 1694

The family of retired FBI agent Robert Levinson says U.S. government officials have concluded that he has died while in the custody of Iran. The family says in a statement posted on Twitter that it did not have information about how or when Levinson had died, but it occurred before the recent coronavirus outbreak. The family says it “will spend the rest of our lives without the most amazing man, a new reality that is inconceivable to us.” Levinson disappeared on Iran's Kish Island in 2007 while on an unauthorized CIA mission.President Donald Trump was asked whether he was aware of the reports. He said Levinson's status "wasn't looking good," but did not accept reports that Levinson has died. 713
