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

ENSENADA, Mexico (KGTV) — A San Diego dirt bike racer is recovering tonight in Mexico after a bizarre mid-race crash with a mystery SUV.On Saturday morning, about 60 miles southeast of Ensenada, 29-year-old Josear Carrasco was racing a course he knew well. On this day, he would not finish."Just devastated. It's really hard. He's my everything, so it's hard to see him like this," said his wife, Kylie.Kylie was in a truck along the course when she got the news. Josear was in second place, nearly done with his 100-mile stretch and about to turn his bike over to a teammate. That's when he says he collided with an SUV that had driven onto the course, headed toward him. "He tried to veer off to the right ... the car veered off in same direction. Then, a head-on collision. He doesn't remember anything after that," said Kylie.Josear was discovered by spectators and a teammate, with car parts scattered nearby."Something exploded. When they found him, his gear was just melted off," said Kylie.Josear suffered second-degree burns up and down the left side of his body and broken bones in his arms, legs, shoulder and shin. He also suffered a ruptured intestine, but he was alive."Once I saw him breathing, my heart dropped ... because that's all that matters," said Kylie.Josear has already undergone several surgeries at a hospital in Ensenada. His family trying to raise money for a medical transport back to San Diego, while Mexican authorities hunt for the hit-and-run driver. A GoFundMe campaign has been set up to help his family with expenses. 1562

Experts say the coronavirus pandemic has led to a decline in both planned and unplanned pregnancies.Experts added that people are meeting less because of COVID restrictions, job loss, and the uncertainty of the future has caused people to hit pause on having kids.On Wednesday, Modern Fertility published a survey that found out of nearly 4,000 people, 30% of them said they had changed their fertility plans due to the pandemic.In March, Modern Fertility found that 31% of those surveyed had decided to change their family planning timelines.Several reasons people gave behind their decision to delay having children was “it doesn’t seem like a good time to bring kids into the world,” “I need to improve my financial position,” and “I’m worried about contracting COVID-19.”On Thursday, the Brookings Institute projected that Americans would see 300,000 fewer births next year. 886

  

Farmers across the country are hard at work preparing their summer harvest. After a devastating spring, they're seeing the market may be picking back up."We did see kind of a dip in produce buying in that mid-April period, a pretty significant dip in produce buying. But we began to normalize and climb out of that dip as we headed into May," said Ian Lemay, the President of the California Fresh Fruit Association.Lemay said farmers are now cautiously optimistic about the summer harvest, which is full of stone fruits like peaches, nectarines and plums."As long as the consumer has been able to make it into the grocery store, which as shelter in place has been eased, we've seen a bit more of a normalization of purchasing habits," Lemay said.When the COVID-19 pandemic first hit, some farmers were forced to throw out their crops or leave them in the fields to rot as supply chains crumbled, and demand quickly shifted. Some farmers can adjust their crops according to demand. Others, like stone fruit growers, have permanent crops like trees and vines that will produce fruit no matter what is happening to the market."We don't have the ability to throttle back or stop the harvest," said Tricia Stever Blattler, the Executive Director of the Tulare County Farm Bureau in California. "A permanent orchard that grows stone fruit like nectarines and peaches, plums or grapes, and certainly we can't tell our dairy cows to stop giving milk."Blattler said packing houses are facing longer production times due to new COVID-19 safety processes, but they're still able to put out plenty of produce. She is concerned, though, that the economic downturn will affect what shoppers buy at the grocery stores."Specialty produce, fresh eating produce will suffer and be less chosen. Less than it would in a good economic cycle," Blatter said. "People are going to buy the canned goods and more affordable choices at the grocery store and maybe skip some of those items that they see to be a little bit pricier like specialty crops."Farmers will also be at the whim of international markets, as many export up to 40% of their produce. The California Fresh Fruit Association is also hopeful that schools will be open in the coming months, as much of their fruit goes into a number of school lunch programs."We're hoping that meaningful plans by different educational institutions can be laid out, and maybe schools are back operating this fall," Lemay said. "We obviously like to get fresh fruit in the hands of children, and if they're not in school, it gets a little bit more difficult."As for what the near future holds for produce farming, many are hopeful that demand will continue. 2686

  

Employees at the Buffalo Museum of Science found something they didn't know they had in their collection.According to Kathy Leacock, director of collections, that isn't difficult to do considering that the museum has over "700,000 items in their collection."What they found was an egg from the now extinct Elephant Bird. It's huge to say the least, weighing 3 1/2 pounds. The egg was not really lost, it was just thought to be a model or a replica. That's how it had been mislabeled for many years. "We found in our documentary evidence that's it's been here since 1939," Leacock said. There are only a handful of the rare eggs in existence.The Elephant Bird is believed to have gone extinct around the 17th century. This egg, thought to be priceless, will go on display at the Museum of Science May 1st. You can get more information at the museum's website.  902
