The Pac-12 has set Sept. 26 as the start of its 10-game conference-only football schedule. The Pac-12 announced three weeks ago it would eliminate nonconference games for its 12 member schools.. The new plan adds an additional cross-divisional game to each team’s slate and moves the conference championship game back two weeks to Dec. 18 or 19. That game was set to be played for the first time at the new NFL stadium in Las Vegas. It will now be hosted by the highest-seeded team.“From the onset of the COVID-19 crisis, we have been committed to prioritizing the health and safety of our student-athletes and all those connected to our athletic programs,” said Pac-12 Commissioner Larry Scott. “The schedule and plans approved today and path to return to competition are subject to public health orders and will be taken in accordance with the health and well-being guidelines developed by our Pac-12 Medical Advisory Committee. The schedule and return to play plans provide for maximum flexibility and the best opportunity to play all fall sports in an environment that prioritizes safety. At the same time, we will continue to evaluate the best available science, data and advice of public health officials as we make decisions and any required adjustments going forward.” 1284

The hunter becomes the hunted!In April, a nature photographer along Florida's Gulf Coast captured some incredible images of an osprey with a fresh kill, flying hundreds of feet in the air.The man who took the stunning pictures, Doc Jon, said he knew he took some great shots. But when he looked at them on his computer, they got even better.He noticed that the prey, which he thought was a fish, was in fact a small shark.Then, he saw the shark also had prey clenched in its jaws -- a small fish!It was a lucky, double payday for the osprey.  I guess you could say: a bird in the hand is worth two in the bush or a fish in the talons is worth two in the nest.The photos have been shared thousands of times since being posted.Courtesy CNN Newsource 795

The National Transportation Safety Board is finishing up its initial examination into the deadly Southwest Airlines engine failure Thursday -- but many questions remain unanswered.Investigators can't explain with certainty why the left engine of Southwest Airlines Flight 1380 malfunctioned when the plane was reaching over 32,000 feet. It's too soon to determine what happened, said National Transportation Safety Board Chairman Robert Sumwalt."I know people would want answers right away. We would do a very methodical investigation," Sumwalt told reporters Wednesday in Philadelphia. "Right now, we just want to document everything that we can." 656

The NFL and the players' union have sent a planner to the 32 teams outlining procedures for the full reopening of their practice facilities.A lengthy memo written by Commissioner Roger Goodell and approved by the NFL Players Association described protocols focusing on screening, testing, infection prevention, and treatment for COVID-19, including response for new infections. In the memo, which CBS Sports' Jonathan Jones shared via Twitter, gives details on how NFL officials want teams to reconfigure their locker rooms to keep lockers 6-feet apart. 561

The month of March for Diana Berrent was one she could’ve done without. The 46-year-old woman was one of the first people in New York State to catch COVID-19.To this day, she's still living with residual symptoms six months later.“COVID is supposed to go away like the flu, and it’s not necessarily going away after two weeks,” she explained.In an effort to help find treatments and develop a vaccine, Berrent has been donating plasma as often as she can. It's in her antibodies, where the key to fighting this virus may lie.Dr. Wesley Self, a researcher at Vanderbilt University Medical Center, has spent the last few months trying to figure out what antibodies are telling us about COVID-19 and how to fight it.“Understanding how the immune system responds to the virus will help development of the vaccines,” Dr. Self said.Dr. Self and his colleagues spent the last few months studying 3,000 people. All of them were healthcare workers who had tested positive for COVID-19. They found that a majority of people who had the most severe cases started out with the most antibodies. But the study also found after 60 days, almost everyone who had coronavirus lost all antibodies.That could be bad news when it comes to our bodies' ability to fight off the virus a second time.“The antibodies are one piece of the immune system. It’s possible they’ll ramp up again quickly and prevent reinfection,” Dr. Self added.All of this also means researchers now need to get blood samples from people fairly quickly after they're infected before antibodies disappear.“We need to be thoughtful about vaccines and treatments that are specific for this virus,” he said. 1662
