MLB and the MLBPA jointly announced on Friday that 31 players tested positive for COVID-19 this week amid the first round of tests as players resume training ahead of this year’s shortened season.Teams began working out this week at ballparks across the US as the coronavirus-shortened season is slated to get underway in three weeks. As part of MLB’s plan to resume, players and support staff will be frequently tested for the virus.But MLB is unique insofar that other major team sports in the US are planning on resuming play in hub cities instead of traveling from city to city. Both the MLS and NBA will play out of Orlando, Florida, while the NHL will resume in the near future at two yet-to-be determined hubs..All told, MLB said it conducted 3,185 samples, with 1.2% coming back positive. In addition to 31 players testing positive, seven staff members also had a positive COVID-19 result.Nineteen of MLB’s 30 teams had at least one player or staff member test positive for the virus 999

NASA has unveiled its billion plan to send the first woman to the moon.On Monday, the agency said they hope to have a woman and man land on the moon in 2024.“With bipartisan support from Congress, our 21st-century push to the Moon is well within America’s reach,” said NASA Administrator Jim Bridenstine in the press release. “As we’ve solidified more of our exploration plans in recent months, we’ve continued to refine our budget and architecture. We’re going back to the Moon for scientific discovery, economic benefits, and inspiration for a new a generation of explorers. As we build up a sustainable presence, we’re also building momentum toward those first human steps on the Red Planet.”The last time humans landed on the lunar surface was 1972, the agency said.While on the moon, the astronauts will collect samples and conduct experiments for a week before heading home on Orion. 901

Video of the scene showed a cloud of tear gas that sent people running and screaming, including families with young children.The incident forced a temporary closure of the major border crossing into San Diego. 751

Most people, when they retire, get a gold watch. James Harrison deserves so much more than that.Harrison, known as the "Man With the Golden Arm," has donated blood nearly every week for 60 years. After all those donations, the 81-year-old Australian man "retired" Friday. The occasion marked the end of a monumental chapter.According to the Australian Red Cross Blood Service, he has helped saved the lives of more than 2.4 million Australian babies.First, a note about antibodiesHarrison's blood has unique, disease-fighting antibodies that have been used to develop an injection called Anti-D, which helps fight against rhesus disease.This disease is a condition where a pregnant woman's blood actually starts attacking her unborn baby's blood cells. In the worst cases, it can result in brain damage, or death, for the babies.Here's why:The condition develops when a pregnant woman has rhesus-negative blood (RhD negative) and the baby in her womb has rhesus-positive blood (RhD positive), inherited from its father.If the mother has been sensitized to rhesus-positive blood, usually during a previous pregnancy with an rhesus-positive baby, she may produce antibodies that destroy the baby's "foreign" blood cells. That could be deadly for the baby.How Harrison made a differenceHarrison's remarkable gift of giving started when he had major chest surgery when he was just 14, the Australian Red Cross Blood Service said.Blood donations saved his life, so he pledged to become a blood donor.A few years later, doctors discovered his blood contained the antibody which could be used to create Anti-D injections, so he switched over to making blood plasma donations to help as many people as possible.Doctors aren't exactly sure why Harrison has this rare blood type, but they think it might be from the transfusions he received when he was 14, after his surgery. He's one of no more than 50 people in Australia known to have the antibodies, the blood service says."Every bag of blood is precious, but James' blood is particularly extraordinary. His blood is actually used to make a life-saving medication, given to moms whose blood is at risk of attacking their unborn babies. Every batch of Anti-D that has ever been made in Australia has come from James' blood." Falkenmire said. "And more than 17% of women in Australia are at risk, so James has helped save a lot of lives."Why his donations were a game changerAnti-D, produced with Harrison's antibodies, prevents women with rhesus-negative blood from developing RhD antibodies during pregnancy. More than three million does of Anti-D have been issued to Australian mothers with negative blood types since 1967.Even Harrison's own daughter was given the Anti-D vaccine."That resulted in my second grandson being born healthy," Harrison said. "And that makes you feel good yourself that you saved a life there, and you saved many more and that's great.The discovery of Harrison's antibodies was an absolute game changer, Australian officials said."In Australia, up until about 1967, there were literally thousands of babies dying each year, doctors didn't know why, and it was awful. Women were having numerous miscarriages and babies were being born with brain damage," Jemma Falkenmire, of the Australian Red Cross Blood Service, told CNN in 2015. "Australia was one of the first countries to discover a blood donor with this antibody, so it was quite revolutionary at the time."  3451

Moderna announced Thursday they have started giving teenagers their COVID-19 vaccine as part of their study on how the vaccine works in those under 18.Pfizer, the other vaccine maker with an emergency use request for their COVID-19 vaccine in adults before the FDA, started including teens in their trial in October.In the Moderna’s press release, they say the Phase 2/3 study of the mRNA vaccine is now underway and is being conducted on children between the ages of 12 and 18.“We are pleased to begin this Phase 2/3 study of mRNA-1273 in healthy adolescents in the U.S. Our goal is to generate data in the spring of 2021 that will support the use of mRNA-1273 in adolescents in advance of the 2021 school year,” said Stéphane Bancel, Chief Executive Officer of Moderna in a company statement. “We hope we will be able to provide a safe vaccine to provide protection to adolescents so they can return to school in a normal setting.”The Phase 2/3 study from Moderna is being done to test the safety and immunogenicity of the two-dose vaccine they submitted to the FDA for emergency use approval last month.They plan to enroll about 3,000 teenagers in the U.S. in the trial, with each receiving either a placebo or the vaccine in two doses, 28 days apart. 1262
