The fossil of a large egg dating from the time of the dinosaurs has been found for the first time on the continent of Antarctica. In addition to its large size and unique location, this discovery is also challenging how scientists think about marine births millions of years ago.The details of the egg and its discovery were published this week in the journal Nature.The egg, measuring 11 inches long and 7 inches wide, was found back in 2011 by Chilean scientists, and sat in Chile’s National Museum of Natural History, labeled only as “The Thing.” David Rubilar-Rogers was one of the scientists who discovered the fossil and works at the museum. He reportedly showed it to every geologist who visited the museum, hoping someone could identify it. Julia Clark from the University of Texas at Austin visited in 2018.“I showed it to her and, after a few minutes, Julia told me it could be a deflated egg!” Rubilar-Rogers said. 933

The British Broadcasting Corporation has reportedly opened an investigation into how journalist Martin Bashir secured Princess Diana's 1995 interview with the network after a shocking allegation aired during a two-part documentary on the British network ITV on Monday and Tuesday.According to USA Today, Bashir allegedly asked a graphic designer to create fake bank statements to persuade Princess Diana to talk to him on camera.According to the New York Times, doubts rose about how Bashir obtained the interview, but an earlier BBC internal investigation exonerated him.During the Nov. 20, 1995 interview, which aired on the BBC's program Panorama, the Princess spoke about how she desperately wanted her marriage to Prince Charles to work. She also spoke about the pressure from the media and her husband's infidelity that caused her to "escape" in binges of eating and vomiting, the Associated Press reported.According to the AP, an estimated 15 to 20 million viewers watched the Princess discuss her life, her children, and her estranged husband Prince Charles. 1074

The first experimental COVID-19 vaccine in the U.S. is on track to begin a huge study next month to prove if it really can fend off the coronavirus, while hard-hit Brazil is testing a different shot from China.Where to do crucial, late-stage testing and how many volunteers are needed to roll up their sleeves are big worries for health officials as the virus spread starts tapering off in parts of the world.Moderna Inc. said Thursday the vaccine it is developing with the National Institutes of Health will be tested in 30,000 people in the U.S. Some will get the real shot and some a dummy shot, as scientists carefully compare which group winds up with the most infections.With far fewer COVID-19 cases in China, Sinovac Biotech turned to Brazil, the epicenter of Latin America’s outbreak, for at least part of its final testing. The government of S?o Paulo announced Thursday that Sinovac will ship enough of its experimental vaccine to test in 9,000 Brazilians starting next month.If it works, “with this vaccine we will be able to immunize millions of Brazilians,” said S?o Paulo′s Gov. Joao Doria.Worldwide, about a dozen COVID-19 potential vaccines are in early stages of testing. The NIH expects to help several additional shots move into those final, large-scale studies this summer, including one made by Oxford University that’s also being tested in a few thousand volunteers in Brazil.There’s no guarantee any of the experimental shots will pan out.But if all goes well, “there will be potential to get answers” on which vaccines work by the end of the year, Dr. John Mascola, who directs NIH’s vaccine research center, told a meeting of the National Academy of Medicine on Wednesday.Vaccines train the body to recognize a virus and fight back, and specialists say it’s vital to test shots made in different ways — to increase the odds that at least one kind will work.Sinovac’s vaccine is made by growing the coronavirus in a lab and then killing it. So-called “whole inactivated” vaccines are tried-and-true, used for decades to make shots against polio, flu and other diseases — giving the body a sneak peek at the germ itself — but growing the virus is difficult and requires lab precautions.The vaccine made by the NIH and Moderna contains no actual virus. Those shots contain the genetic code for the aptly named “spike” protein that coats the surface of the coronavirus. The body’s cells use that code to make some harmless spike protein that the immune system reacts to, ready if it later encounters the real thing. The so-called mRNA vaccine is easier to make, but it’s a new and unproven technology.Neither company has yet published results of how their shots fared in smaller, earlier-stage studies, designed to check for serious side effects and how well people’s immune systems respond to different doses.Even before proof that any potential vaccine will work, companies and governments are beginning to stockpile millions of doses so they can be ready to start vaccinating as soon as answers arrive.In the U.S., a program called “Operation Warp Speed” aims to have 300 million doses on hand by January. Under Brazil’s agreement with Sinovac, the Instituto Butantan will learn to produce the Chinese shot.___AP journalist Marcelo Silva de Sousa contributed to this report.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

The deadly wildfires are not only destroying homes and burning everything in their path -- but they're also causing poor air quality.On Tuesday, a thick haze blanketed parts of the Northwest, including Seattle, as fires across the border in Canada burned.The smoke that is blanketing Washington, Oregon and California is smoke coming from the wildfires burning in British Columbia, according to the National Weather Service Seattle.Air quality advisories are in effect for portions of Washington and Oregon, according to the NWS. 537

The COVID-19 pandemic has been a difficult and stressful time for families, but we're seeing one silver lining when it comes to fathers and their kids.Nearly 70% of dads in a recent study from the Harvard Graduate School of Education say they're feeling closer to their kids right now.The dads have had to be home more than usual, but one of the people involved with the study also believes it's helping that dads may be less distracted with work than they usually are.Also, parents' social lives have changed, so they're doing things with their kids they may have done with their friends previously.Dads in the study say they're also getting to know their kids better. More than half say they're spending more time talking to their children about things that are important to them.“I think we're all better parents when we know our kids better,” said Richard Weissbourd, who directs the Making Caring Common Project at Harvard. “I mean it's respectful to enable our kids to really speak, but we also learn a lot about them and it deepens our relationships with them and it also helps us I think in being mentors and guides to them when they make key decisions in their lives.”The Making Caring Common Project is a national effort to make moral and social development priorities in raising kids.Weissbourd is worried there will be a strong pull to return to our normal lives and dads' relationships won't continue in the same way.But you can take steps now to keep those bonds.“I really encourage fathers to establish rituals and routines with their kids now, like if you're going for a walk every weekend with your kid, continue doing that even when the pandemic is over,” said Weissbourd. “If you're playing games with your kid, develop a ritual around playing games with your kids or activities.”He says more fathers are also watching TV with their kids and talking with them about what's going on in the world surrounding the pandemic and the protests. He's hopeful that ritual will continue too. 2008
