ESCONDIDO, Calif. (KGTV) -- The San Diego Zoo is now five years into its ambitious attempt to save a critically endangered species, the Northern White Rhino, from extinction. There are currently just two Northern White's still alive, both females who are unable to give birth. They live at a preserve in Kenya.“It’s the only thing that keeps me going, thinking that this is possible and that we can save a species," says Dr. Marisa Korody, part of the team working on the project. The concept sounds like a science fiction novel. The plan is to take skin cells from Northern White rhinos preserved at the Safari Park's Frozen Zoo. Using Nobel Prize-winning technology developed 14 years ago, Dr. Korody is working to use those skin cells to make stem cells. Stem cells can then be converted into any other kind of cell. In this case, the genetically pure Northern White Rhino sperm and eggs that could be used for in vitro fertilization, with Southern White Rhinos, a close genetic cousin of the Northern White, to use as surrogate mothers. Dr. Korody says her team has made great progress, including successfully turning skin cells from Angilifu, a male Northern White rhino who died at the Safari Park in 2014, into stem cells and turning those stem cells into heart cells. They even recorded incredible video of those living heart cells beating in a petri dish. “We basically jumped up and down in the lab. That was probably one of the most exciting days we’ve had. We were pulling people in from the hallways to say, come look and see what we did.” Along with the cell portion of the project, tremendous progress has also been made with the in vitro research. This fall, the Zoo celebrated the first birthdays of two Southern White Rhinos who were born using the technology the team hopes to use with the Northern White embryos. “These two, Edward and future, are so healthy, so happy, so well-adjusted. I don’t have children of my own, but I think it must be the same kind, on some scale, of pride you feel in your own children," said Dr. Barbara Durrant, who leads that portion of the project. When ABC 10News first began covering the Northern White Rhino plan in 2015, Dr. Durrant estimated it would be ten years before a Northern White calf would be successfully born. Now halfway through that timeline, she says she believes they are right on track. 2366

Even as the U.S. hit a single-day record of new coronavirus cases this month, the CDC’s latest statement calls for schools to reopen. But critics say there is vague guidance for what happens if there is a school outbreak.As states across the country weigh the risks of reopening schools this fall, the message from the White House has been loud and clear.Last week, President Donald Trump stated he would like schools to reopen, stating, “Yeah, I would like to see the schools opened, open 100 percent.”Most doctors, educators, and psychologists agree that going back to school would be in the best interest of students. But what happens if just one student contracts the coronavirus? Would that force a shutdown?Some health experts are wary.“Once you start getting into dozens, or even more kids and teachers starting to get infected, it's going to be very hard to keep that school open, said Dr. Ashish Jha, a professor of medicine and the director of Harvard University’s Global Health Institute.“We have to have really smart planning and we have to have a clear protocol for how to identify kids and teachers and staff who get infected and then know what to do when we identify them. I just haven't seen that kind of clear protocol yet.”Late last week, the CDC did issue new guidelines for school reopening. They include encouraging social distancing, spacing out desks and requiring face coverings.But the guidance leaves it up to states, schools and local health departments how to precisely handle an actual outbreak.“What we have is patchwork, not just across states, but even within states across communities,” said Dr. Jha. “States are turning over the responsibility to individual communities and saying, ‘You figure it out.’”Recommended strategies from the CDC’s guidelines include:Immediately separating staff and children with COVID-19 symptomsSetting up safe transport for anyone who is sick to their home or to a healthcare facilityClosing off areas used by a sick person, cleaning and disinfecting after 24 hours when possibleImmediately notifying health officials, staff, families and anyone who may have had close contact with an infected person while maintaining confidentiality lawsStill, there is concern.A recent survey from The Associated Press-NORC Center for Public Affairs Research found, “46 percent of Americans believe schools need major modifications to deal with the coronavirus pandemic, and another 31 percent think they shouldn’t reopen for in-person learning at all.”“We can open schools safely but key to that is making sure the level of community transmission is pretty low, so you don't have sort of raging wildfires in the community,” said Dr. Jha. “Because it's going to be very hard to keep those fires out of the school.” 2772
