WASHINGTON — U.S. health officials have started two new studies to test various blood thinners to try to prevent strokes, heart attacks, blood clots and other complications in COVID-19 patients.Doctors increasingly are finding blood clots throughout the bodies of many people who died from COVID-19 along with signs of damage they do to kidneys, lungs, blood vessels, the heart and other organs.National Heart, Lung and Blood Institute Director Gary Gibbons says that hospitals have been giving seriously ill patients anti-clotting drugs to try to prevent this, but “quite frankly, we didn’t know how best to treat it” in terms of which drugs or doses to use and at what stage of illness.The National Institutes of Health will coordinate a study in hospitalized patients comparing low and regular doses of the blood thinner heparin. The study will involve more than 100 sites around the world participating in a research effort with various governments, drug companies, universities and others to speed coronavirus therapies.A second study in COVID-19 patients not sick enough to need hospitalization will test various strategies against placebo pills: baby aspirin or low or regular doses of the anti-clotting drug apixaban, sold as Eliquis in the United States. The goal there is preventing blood clots or hospitalization.A third study starting later will test blood thinners for people who have recovered and no longer test positive for the coronavirus. Evidence is building that they may remain at higher risk for blood clots. 1538

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

Want to see 16 sunrises in one day? Float in zero gravity? Be one of the few to have gazed upon our home planet from space?In just four years' time, and for an astronomical .5 million dollars, it's claimed you can.What's being billed as the world's first luxury space hotel, Aurora Station, was announced Thursday at the Space 2.0 Summit in San Jose, California.Developed by US-based space technology start-up Orion Span, the fully modular space station will host six people at a time, including two crew members, for 12-day trips of space travel. It plans to welcome its first guests in 2022."Our goal is to make space accessible to all," Frank Bunger, CEO and founder of Orion Span, said in a statement. "Upon launch, Aurora Station goes into service immediately, bringing travelers into space quickly and at a lower price point than ever seen before."Astronaut experienceWhile a million trip is outside the budget of most people's two-week vacations, Orion Span claims to offer an authentic astronaut experience.Says Bunger, it has "taken what was historically a 24-month training regimen to prepare travelers to visit a space station and streamlined it to three months, at a fraction of the cost."During their 12-day adventure, the super-rich travelers will fly at a height of 200 miles above the Earth's surface in Low Earth Orbit, or LEP, where they will witness incredible views of the blue planet.The hotel will orbit Earth every 90 minutes, which means guests will see around 16 sunrises and sunsets every 24 hours.Hometown heroActivities on board include taking part in research experiments such as growing food while in orbit -- which guests can take home for a super-smug souvenir -- and soaring over their hometown.Guests can have live video chats with their less-fortunate loved ones back home via high-speed wireless Internet access and, upon return to Earth, will be greeted with a specially arranged hero's welcome.While enjoying the thrills of zero gravity, the travelers will be able to float freely through the hotel, taking in views of the northern and southern aurora from the station's windows.Deposits are already being accepted for future stays on the space hotel. The ,000 is fully refundable, should applicants find themselves unable to rise to the full .5 million.Travelers will complete a three-month Orion Span Astronaut Certification (OSAC) program before take-off. Orion Span has a team of space industry veterans who together have more than 140 years of human space experience.Chartered tripsOrion Span isn't the only venture boldly pushing the frontiers of elite travel into space.Axiom Space, a Texas-based company with a former International Space Station manager at the helm, has plans to put a commercial space station in orbit by 2024.It says it will begin to take tourists to the ISS in 2019 and later to its own station.As yet, Axiom hasn't priced its off-world excursions, but says it'll be considerably lower than the tag paid by previous space tourists like Dennis Tito, who stumped up a reported million for a seven-day trip in 2001.Virgin Galactic, founded by Richard Branson with the aim of taking passengers briefly into sub-orbital space, will charge for 0,000 for its trips. Branson originally said flights would begin in 2009, but an official date has yet to be set for its maiden voyage.Whatever the price tag, the tourist demographic with spare cash for space jaunts is presumably quite small.However, Bunger says that Aurora Station "has multiple uses beyond serving as a hotel."It plans to offer fully chartered trips to space agencies and support zero gravity research and space manufacturing.Adds Bunger: "Our architecture is such that we can easily add capacity, enabling us to grow with market demand."Orion Span's next mission? To launch the world's first condominiums in space.The-CNN-Wire 3876

VISTA, Calif. (KGTV) -- Authorities are searching for a suspect they say groped a 14-year-old girl at a Vista restaurant.According to the San Diego County Sheriff’s Department, a man walked into the Panda Express on Main Street in Vista and grabbed a 14-year-old on the buttocks on March 21.The department says the man then left the restaurant driving a black sedan.The suspect is described a black man between 35 to 45-years-old who is five feet, nine inches tall and weighs about 200 pounds.Anyone with information is asked to call Crime Stoppers at 888-580-8477. 573

VISTA, Calif. (KGTV) — A group of teachers with the Vista Unified School District rallied Thursday against the district's current reopening plan.The district's Board of Education voted late Thursday to finalize a plan to bring students and teachers back to in-person learning on Oct. 20. The group of teachers say there's now a chance they hold a vote over whether to vote of no confidence in the district's superintendent on Monday."We now face a rush to open without the protocols in place to ensure the health and safety of all stakeholders. School board members’ openly dismissive behavior toward educators and their safety concerns is hurtful and disappointing to every committed educator who calls VUSD their professional home," said Keri Avila, president of the Vista Teachers Association. "We are extremely disappointed in the lack of concern expressed at last night’s board meeting for the health and safety of students, teachers, and staff. We have scheduled and emergency executive board meeting to determine next steps."The board heard from parents and teachers on both sides. Some said they are for the full reopening, while others said bringing students back at normal capacity is too risky.Many teachers have expressed concerns that the plan just isn't safe enough during a pandemic."I think it's reckless, I think it's misguided," said Craig Parrot, an eighth-grade science teacher at Roosevelt Middle School. "There are entire schools in our district that don't have windows that open, kids are coming in without temperature checks."Parents that want to keep their students in virtual distance learning may do so.While many school districts have limited the number of students returning in-person, Vista Unified's website states, "It is important to note that while many health and safety precautions are in place for the Vista Classic learning model, all classrooms will have the normal amount of students enrolled. This means that while we will be following social distancing procedures, student seating arrangements will be less than six feet apart."Parrott said he was able to continue with distance learning because a colleague who teaches the same subject will return in-person. "The kids are too close, we have desks that are 6 inches or 12 inches apart," said Parrott.The Vista Teachers Association (VTA) sent ABC 10News pictures showing what they call a lack of spacing in between desks in some classrooms.Members of the VTA worry about the spread of COVID-19 as teachers and students return to school. Avila started a petition demanding that the Vista Unified Board of Education Trustees modify the reopening plans."We want our district to mitigate the 'Four C's', that is close, closed, crowded and continuous," said Avila. "They're going to be in crowded conditions especially if we have 38 kids in a room at one time."The district's Superintendent of Schools, Dr. Matt Doyle, sent the following statement to ABC 10News. 2958
