To end the pandemic, there need to be enough people immune to COVID-19 and there are two ways to do that: immunity through infection or from a vaccine."I think racing to herd immunity is the dangerous thing that I’m concerned about," said Dr. Stuart Ray, a professor of medicine at Johns Hopkins University School of Medicine.Herd immunity is when the spread of the infection cannot be sustained because the number of people who are immune is high enough. Some countries are considering it as a strategy to combat COVID-19.But Ray said it could not work in the US unless much more effective treatments are developed.He says on average, a newly infected person infects two others, so to have herd immunity from COVID-19 about 60 percent of people would have to become immune."We would have something like another 100 million people, maybe more, infected. 150 million more and even if the major complication rate is a fraction of 1 percent, we will still have huge numbers of deaths," said Ray.He said we also don’t know if just having had the infection once will create lasting immunity to control the spread."It possible that you could be immune enough not to get sick and still not immune enough to prevent that spread and so herd immunity is a tough bar for us to aim for because not only do we need 60 percent of people to be immune but we need them to be immune in a way that prevents them from infecting other people," said Ray.The other way to achieve herd immunity would be through a vaccine."Vaccines can work better, provide better immunity than the natural infection does. The new shingles vaccine provides great immunity and protects more than 95 percent of people from getting shingles," said Ray.Several vaccines are still going through the last phase of clinical trials to see if any also creates enough immunity to prevent passing the virus along.This story was first reported by Abby Isaacs at WMAR in Baltimore, Maryland. 1946

There is no God -- that's the conclusion of the celebrated physicist Stephen Hawking, whose final book is published Tuesday.The book, which was completed by his family after his death, presents answers to the questions that Hawking said he received most during his time on Earth.Other bombshells the British scientist left his readers with include the belief that alien life is out there, artificial intelligence could outsmart humans and time travel can't be ruled out.Hawking, considered one of the most brilliant scientists of his generation, died in March at the age of 76."There is no God. No one directs the universe," he writes in "Brief Answers to the Big Questions.""For centuries, it was believed that disabled people like me were living under a curse that was inflicted by God," he adds. "I prefer to think that everything can be explained another way, by the laws of nature."Hawking suffered from amyotrophic lateral sclerosis (ALS), a neurodegenerative disorder also known as Lou Gehrig's Disease, for most of his adult life.The scientist died while still working on the book, which his family and colleagues finished with the help of his vast personal archives.'Increasingly looking inward'While Hawking spoke of his lack of belief in God during his life, several of his other answers are more surprising."There are forms of intelligent life out there," he writes. "We need to be wary of answering back until we have developed a bit further."And he leaves open the possibility of other phenomena."Travel back in time can't be ruled out according to our present understanding," he says. He also predicts that "within the next hundred years we will be able to travel to anywhere in the Solar System.""He realized that people specifically wanted his answers to these questions," the scientist's daughter, Lucy Hawking, who helped complete the book, told CNN.Hawking saw the world on the brink of a "vast transformative change" when he died, she noted, adding: "He's asking us not to go into the future blindly. How good is the track record of the human race in using advances in technology for the good of ordinary people?"In remarks prepared by Hawking and played at the launch of the book in London on Monday, the scientist also turned his attention to the world he was leaving behind."With Brexit and Trump now exerting new forces in relation to immigration and the development of education, we are witnessing a global revolt against experts, and that includes scientists," Hawking said.Hawking had been a critic of the United Kingdom's decision to leave the European Union, and called Donald Trump a "demagogue" in 2016.His greatest concern, his daughter said, "is how divided we've become," adding: "He makes this comment about how we seem to have lost the ability to look outward, and we are increasingly looking inward to ourselves."Hawking's final message to readers, though, is a hopeful one.Attempting to answer the question "How do we shape the future?" in the book's final chapter, the scientist writes: "Remember to look up at the stars and not down at your feet." 3096

"You are live on the Oscars right now."The rest of the celebs then trailed in as the moviegoers lept from their seats.The stars brought along some snacks, including candy, a 6-foot submarine sandwich and hot dogs shot out of hot dog guns.Kimmel said it was a good thing too as, according to the host, there was a distinct smell of marijuana in the air."Do not aim the hot dogs at the vegetarians," Kimmel joked.The host explained the stunt to the audience."We were talking about our appreciation for people who go to the movies and those are you people, so we wanted to say thank you to the moviegoers," Kimmel said. 1272

There’s a new resource for parents who’ve found themselves struggling to teach their children while maintaining a job.“We're stepping into this role that we have no experience,” said Amy Lundy, co-founder of The Learning Match. “And as far as education is concerned, they're teaching subjects in a way that we didn't even learn them as children.”Lundy found herself trying to juggle schooling three children from home and keeping her business running through the pandemic. Quickly, she started looking for help with the schooling aspect.“I realized this is a service I needed in my own family. What I was finding was I was connecting with a lot of teachers that friends were using. Their schedules were very filled. I couldn't get them when I needed them. I was going on a Facebook groups. I was having a very hard time navigating and finding people that fit the qualifications,” said Lundy.That's how TheLearningMatch.com was born. It's a website that's like a matchmaking service. It connects people studying education or retired teachers, really anyone with an educational background, to families that need help.The educator may just be there for accountability to make sure the child is doing and understanding assignments. Or they could play a more involved role.“And then there's more sort of part-time or full-time experiences where this person is coming inside your home or is on the computer several hours a day, or all day with your child, fulfilling those requirements that you have based on what your child's grade is,” said Lundy.Its free to sign up on The Learning Match. The site leaves it to families and the educators to work out how involved and how much their services will cost. 1706
