Half of the coral populations in the Great Barrier Reef off Australia’s coast have been killed off because of warming ocean waters, a new study says.Between 25-30 percent of all marine species rely on coral reefs at some point in their life cycle. The Great Barrier Reef is the world’s largest coral reef, covering nearly 133,000 square miles.It has more than 411 species of hard corals documented, as well as 1,500 species of fish and other animals.Researchers looking at coral populations over 30 years starting in 1995 found there was decline in both shallow and deeper water, and across different species. They said two in particular, branching and table-shaped corals, were especially hard hit in 2016 and 2017 because of record-breaking temperatures.The study finds climate change to be a key driver in reef disturbances that disrupt recovery.“The potential for recovery of older fecund corals is uncertain given the increasing frequency and intensity of disturbance events. The systematic decline in smaller colonies across regions, habitats and taxa, suggests that a decline in recruitment has further eroded the recovery potential and resilience of coral populations,” the researchers note.They also say the coral that spawn the larvae that makes more coral have declined dramatically over large stretches of the reef.“Corals are tremendously resilient because of their capacity to produce millions of babies but they/we desperately need a break from disturbances,” Andreas Dietzel, a professor at the ARC Center and a co-author of the paper, said in an email to the Washington Post. 1600

HAWTHORNE (CNS) - Southern California-based SpaceX will look to achieve another milestone late Friday evening when it attempts to launch the first test flight of its sleek capsule designed to carry astronauts to the International Space Station.The Crew Dragon, a stepped-up version of SpaceX's Dragon spacecraft that is used to carry cargo to the Space Station, is scheduled for to launch at 11:49 p.m. California time Friday from Cape Canaveral in Florida, propelled by a Falcon 9 rocket. The Crew Dragon mission will be unmanned, testing the new ship's capabilities and ability to self-dock at the Space Station.PHOTO GALLERY: SPACEX ROCKET LAUNCH LIGHTS UP EVENING SKYCargo-carrying Dragon capsules are usually captured by the Space Station's robotic arms and brought into the docking bay. The Crew Dragon is designed to dock and un-dock on its own.The Crew Dragon being launched Friday night will be carrying a sensor- laden mannequin, outfitted in a SpaceX spacesuit, along with about 400 pounds of supplies and equipment. The spaceship is expected to arrive at the International Space Station at about 3 a.m. California time on Sunday.The ship will remain docked at the station until about 11:30 p.m. Pacific time March 7, when it begins its journey back to Earth. It is expected to splash down in the Atlantic Ocean -- slowed by four parachutes -- about six hours later.VIDEO REPORT: No, it was not a UFO. SpaceX launches rocket into space off California coastAssuming the test flight goes well, SpaceX is scheduled to actually launch astronauts into space for a short demonstration flight this summer, possibly in July. NASA has already chosen astronauts Robert Behnken and Doug Hurley for the historic mission. Assuming no issues with that flight, two other astronauts -- Victor Glover and Mike Hopkins -- will later become the first humans carried by a Crew Dragon spacecraft to the International Space Station. 1929

Health care worker Amanda Solt is one of the lucky COVID-19 patients who survived the disease.“I remember them pulling my arms up over my head, under my pillow and then they took the pillow, and that's the last thing I remember,” said Solt.She was in the hospital and ICU for weeks back in June. It wasn't until she received a convalescent plasma donation that she started to turn a corner.“They helped me hold the phone up to my ear, so I could give a verbal consent. To help me sit me up in the bed, literally, they were holding me and helping me sign the paper, so I could give consent. And I just remember the nurses were like, ‘say yes.’ Yes, I remember that and honestly, I feel like I owe my life to them and to the person who donated for sure.”The nurses helped Solt take a picture the moment she got the plasma. She says it saved her life and now she's advocating for others to donate.Health and Human Services Secretary Alex Azar also pushed for donations Wednesday during a briefing on vaccines. HHS is increasingly concerned about supply with rising cases.Plasma is given to hospitalized patients earlier now.People with COVID antibodies can donate plasma as often as every seven days for up to three months. Just one donation can help up to four people.“You have the chance to truly, truly make a difference in life or death for somebody,” said Solt.The American Red Cross saw their distributions of convalescent plasma increase 250% in November compared to September. You can make an appointment to donate online through their app or over the phone. 1571

GUERNEVILLE, Calif. (AP) — Tom Orr began moving lyrics and scripts, clothes and photo albums from his apartment as authorities ordered evacuations along a rapidly rising Northern California river that was threatening to reach a historic crest.But the actor and writer couldn't move costumes, computers and performance videos. So he shifted those to his loft bed about 10 feet up and prayed they would survive. On Wednesday, television news footage showed muddy brown water nearly swallowing his ground-level unit and much of the tiny town of Guerneville, part of Sonoma County's famed wine country and a popular tourist destination.Residents woke up Thursday to assess the damage as water started receding. Orr, 48, was among those still unable to get into his house after the rain-swollen river climbed to its highest peak in more than 20 years."I feel so helpless just sitting here and waiting before I can go back and start salvaging whatever I can," Orr said in text messages to The Associated Press before preparing for a friend to take him by canoe to work at the Main Street Bistro, one of the few places in town that did not flood.The Russian River in wine country north of San Francisco crested at more than 46 feet (14 meters) Wednesday night, and floodwaters were receding after a two-day storm inundated the area. One National Weather Service station measured 20 inches of rain in 48 hours.While no flood-related serious injuries or deaths were reported in Sonoma County, a man about 150 miles (330 kilometers) to the north in Ferndale died trying to rescue three children.The unidentified man was trying to walk from a barn to his home through up to 5 feet (1.5 meters) of water Wednesday evening when he was carried away by the fast-moving current, said Samantha Karges, a spokeswoman with the Humboldt County Sheriff's Office.Two adults and a child tried to rescue the man, but their tractor stalled in the water. Deputies in a boat then rescued them and the three children from the home, Karges said.The missing man's body was found Thursday morning. He was the father of a 12-year-old trapped in the home with two children under 4, Karges said. She was not sure if all three children were related. The low-lying rural area about 215 miles (473 kilometers) north of San Francisco is home to many dairy farms and flooded when the Eel River went over its banks.In Sonoma County, Guerneville and Monte Rio were cut off by floodwaters that swamped the communities. About 2,000 homes, businesses and other structures were flooded by water up to 8 feet (2.4 meters) deep and about 3,500 people were under evacuation orders.In addition, two wastewater treatment plants were not working, leading to concerns about sewage spills, said Briana Khan, a Sonoma County spokeswoman.Guerneville, a town of 4,500, is a former logging community now popular with day-tripping tourists, including gays and lesbians who flock to the town's resorts and fine restaurants. Throughout the storm, residents with canoes and kayaks gave rides to neighbors and documented the rising water with photos posted to social media.Locals are accustomed to the Russian River flooding in rainy weather, but not like this.In Monte Rio, 28-year-old Michael Super watched helplessly as water seeped in from five different entry points, including doors and walls. He grabbed the cat and dog and found higher ground.He said the landlord has insurance, but the silt and dirty water are a mess to clean."A lot of the furniture will have to go into the dump," he said. "We've seen oil and gas sheens and alcohol bottles so the water is unsafe."Sandra Jagger, 69, said that within hours of her morning walk Wednesday, the water had reached the bottom of the steps leading to her apartment in Guerneville."It came up real fast," she said. "I was thinking, 'Well it's going to be fine, it'll stop.' But when it started coming up the steps, I got a little nervous."Officials received no calls for help overnight from hundreds of people who stayed in their homes instead of heeding evacuation orders, the Sonoma County Sheriff's Office said in a statement.Orr moved to Guerneville about five years ago, driven out of San Francisco by rising costs. He helped create a dinner theater show at a local restaurant. It didn't work out, but he stayed on, unable to move back to the city.He started moving items out of his house Tuesday afternoon, humming a version of "My Funny Valentine" called "My Floody Valentine" to keep up his spirits. By 10 p.m., the water was too high for him to get inside.He doesn't have insurance, but the items he hopes survive are not easily replaceable: computers, floppy disks and video containing decades of essays, performances, ideas for musicals and "sassy satirical parodies of Broadway show tunes.""It is what it is," he said. "Family and friends across the country are reaching out and offering shelter and funds to help re-locate. I'm lucky."___Har reported from San Francisco. Associated Press Writer Olga R. Rodriguez in San Francisco also contributed to this report. 5075

Here's something scary: Even if you have the legal right to vote and have done everything to prepare yourself for Election Day, you could still be turned away at the polls.In recent years, almost two dozen US states have implemented laws that impose new restrictions on voting, which critics say disproportionally affect minority voters.The stricter laws stem from a 2013 Supreme Court decision that struck down parts of the 1965 Voting Rights Act, which required the approval of the Justice Department before states made any changes to their voting laws.In the last five years at least 23 states have placed restrictions on voting by closing polling places, cutting early voting, purging ineligible voters from electoral rolls and imposing stricter voter ID laws, reports the federal Commission on Civil Rights.With midterm elections around the corner and early voting already underway, it can be a tricky situation for thousands who are just looking to legally exercise their civic right as American citizens.But no matter what unexpected issues you encounter at your polling place, there are ways to make sure your vote gets in safely. Here are some tips. 1166
