WASHINGTON (AP) — For decades, there were tales from fishermen and tourists, even lots of photos, of a mysterious killer whale that just didn't look like all the others, but scientists had never seen one.Now they have.An international team of researchers says they found a couple dozen of these distinctly different orcas roaming in the oceans off southern Chile in January. Scientists are waiting for DNA tests from a tissue sample but think it may be a distinct species.The National Oceanic and Atmospheric Administration felt confident enough to trumpet the discovery of the long rumored killer whale on Thursday. Some outside experts were more cautious, acknowledging the whales are different, but saying they'd wait for the test results to answer the species question."This is the most different looking killer whale I've ever seen," said Robert Pitman, a NOAA marine ecologist in San Diego. He was part of the team that spotted the orcas off Cape Horn at the tip of South America.How different? The whale's signature large white eye patch is tiny on these new guys, barely noticeable. Their heads are a bit more rounded and less sleek than normal killer whales and their dorsal fins are narrower and pointed.They likely mostly eat fish, not marine mammals like seals, as other killer whales do, Pitman said. Fishermen have complained about how good they are at poaching off fishing lines, snatching 200-pound fish away.Pitman said they are so different they probably can't breed with other killer whales and are likely a new species. At 20 to 25 feet long (6 to 7.5 meters), they are slightly smaller than most killer whales. In the Southern Hemisphere, killer whales are considered all one species, classified in types A through C. This one is called type D or subantarctic killer whales.Michael McGowen, marine mammal curator at the Smithsonian, said calling it a new species without genetic data may be premature. Still, he said, "I think it's pretty remarkable that there are still many things out there in the ocean like a huge killer whale that we don't know about."Scientists have heard about these distinctive whales ever since a mass stranding in New Zealand in 1955. Scientists initially thought it could be one family of killer whales that had a specific mutation, but the January discovery and all the photos in between point to a different type, Pitman said.He said they are hard to find because they live far south and away from shore, unlike most killer whales."The type D killer whale lives in the most inhospitable waters on the planet. It's a good place to hide."Pitman got interested in this mysterious killer whale when he was shown a photograph in 2005. When he and others decided to go find them, they followed the advice and directions of South American fishermen, who had seen the whales poaching their fish.After weeks of waiting, about 25 of the whales came up to the scientist's boat, looking like they expected to be fed. Equipment problems prevented the scientists from recording enough of the whale songs, but they used a crossbow to get a tissue sample. Pitman said the whales are so big and their skin so tough that it didn't hurt them, saying the arrow "is like a soda straw bouncing off a truck tire."Pitman said he'll never forget Jan. 21 when he finally saw his first and then a bunch of the type D orcas."For 14 years I was looking for these guys. I finally got to see them," Pitman said.He acknowledged that he did sound like the revenge-seeking captain in the classic novel "Moby-Dick.""I guess I know how Ahab felt, but for a good reason," Pitman said. 3606

WASHINGTON — A new poll finds that only about half of Americans are ready to roll up their sleeves for COVID-19 vaccines, even as states frantically prepare to begin months of vaccinations that could end the pandemic. The survey from The Associated Press-NORC Center for Public Affairs Research shows about a quarter of U.S. adults aren't sure if they want to get vaccinated when their turn comes, and roughly another quarter say they won't. The Food and Drug Administration is poised to decide in the coming days whether to allow emergency use of two candidates, one made by Pfizer and the other made by Moderna. 621

VISTA (CNS) - A Vista vodka distillery that shifted its operations to producing hand sanitizer during the coronavirus pandemic announced Tuesday that it will donate a portion of the proceeds to fund COVID-19 research.Misadventure & Co. said 15% of profits generated by its hand sanitizer sales will go to "scientific research institutions, including The National Institutes of Health Foundation, John Hopkins Medical Foundation and University of California San Diego Health Foundation in the name of COVID-19 research and response."In March, the company pivoted operations to manufacturing hand sanitizer after pandemic restrictions prevented patrons from visiting its distillery or tasting room."We are so thankful that we were able to pivot our business and save jobs when the coronavirus first struck. We want to give back by donating to institutions that will help find a vaccine," said co-founder Sam Chereskin."Now just like our sustainable vodka, consumers can feel good about purchasing their hand sanitizer through our website because they know they will support efforts to end this pandemic," he said. ``We call on more companies to join this movement and help donate a portion of their proceeds in a similar manner." 1239

  

WASHINGTON (AP) — Navy officials said Wednesday they are pulling achievement medals from prosecutors who argued the case against a decorated Navy SEAL who was acquitted in the death of a wounded Islamic State captive after President Donald Trump intervened.Trump tweeted earlier Wednesday that he had directed the secretary of the Navy and the chief of naval operations to "immediately withdraw and rescind" the Navy Achievement Medal from prosecutors who argued the case against Special Operations Chief Edward Gallagher, who was acquitted by military jurors earlier this month."The Prosecutors who lost the case against SEAL Eddie Gallagher (who I released from solitary confinement so he could fight his case properly), were ridiculously given a Navy Achievement Medal," Trump complained, adding, "I am very happy for Eddie Gallagher and his family!"Navy spokesman Cdr. Jereal Dorsey said that on Wednesday, after Trump's tweet, Navy Secretary Richard Spencer rescinded the awards. As secretary, he has that authority, Dorsey said. 1042

  

WASHINGTON — Senate Republicans are proposing changes to police procedures and accountability, according to a draft of a bill obtained by The Associated Press.The JUSTICE Act — Just and Unifying Solutions To Invigorate Communities Everywhere Act of 2020 — would establish an enhanced use-of-force database, restrictions on chokeholds and new training and commissions to study law enforcement and race.In addition to the use-of-force database, the JUSTICE Act would also begin tracking — but would not ban — the use of no-knock warrants. In March, a Louisville woman named Breonna Taylor was killed when police entered her home on such a warrant.The JUSTICE Act is the most ambitious GOP policing proposal in years. It's a direct response to the massive public protests over the death of George Floyd and other black Americans.The package is set to be introduced Wednesday. As the outlines emerged, Democrats said it didn't go far enough.The Justice in Policing Act, a bill introduced by Democrats in the House last week, would introduce more sweeping changes, including a ban on police chokeholds. The Democrats' bill would also amend federal law to make it easier to charge police officers with civil rights violations.The introduction of the GOP bill will be introduced a day after President Donald Trump signed an executive order aimed at changing police practices. Trump's order calls on police departments to utilize social workers in some emergency calls. It also encouraged the formation of a nationwide database to track officers who may be fired from one department in an effort to prevent another department from hiring them. 1643
