SAN DIEGO (KGTV) — San Diego Zoo's 7-month-old endangered Matschie’s tree kangaroo has finally emerged from her mother's pouch. The young "joey" has not been named, but is beginning to spend more time outside her mom, Polly, according to zoo officials.“The joey, right now, cannot get enough things in her mouth,” said Breanne Barney, keeper at the San Diego Zoo Safari Park. “She’s constantly trying to eat leaves, greens, various vegetables, corn—even chewing on moms’ ears, tail, hands and feet!”The little kangaroo doesn't stray far from her mom though, as she learns to climb and maneuver outside of the pouch, the zoo says.Matschie’s tree kangaroos have an estimated gestation period of about 45 days and are about the size of a jelly bean when born. Once born, they crawl back into their mom's pouch and attach to a nipple to gain nourishment and grow. Tree kangaroos remain in the pouch for a few months.“Polly is an excellent mother, and consistently grooming her little one,” Barney said. “Due to their small population numbers, this joey provides a spark of hope for the future of this species.”The kangaroos are listed as endangered on the International Union for Conservation of Nature's list of threatened species. There are less than 2,500 of the kangaroos in their native habitats of Papua New Guinea and the Huon Peninsula.Unfortunately, they are hunted by humans for food and trade, according to the zoo. The zoo's Matschie’s tree kangaroos came to the Safari Park’s Walkabout Australia in 2018 as part of a Species Survival Plan breeding program. 1573

SAN DIEGO (KGTV) -- School grades have been a sensitive topic between parents and their kids for as long most can probably remember.Whether you agree with a report card or not – it's used as a sign of academic performance or to highlight areas that may need improvement.With school back in session, most from a distance, teachers across California are trying to figure out how to properly measure students' learning.Back in March, when stay at home orders were announced, some school districts shifted from the traditional A to F system to credit/no credit grading."Many of them did look to what the universities were asking and what would be in the best interest of students in that before they made a decision," said Dina Wilson, division director at the Los Angeles County Office of EducationThat was five months ago and a temporary measure.A new school year is underway, and each district's current approach to grading could have an impact on students' future and finances."We want to make sure we're doing right by our kids," said San Diego County Superintendent of Schools Dr. Paul Gothold. "We don't want our kids to be at a disadvantage when they start to apply for colleges."Gothold has a strong opinion on how grading should be handled this school year."Letter grades need to be the default practice," he said.The San Diego County Office of Education provides its recommendations, but they don't have to be implemented by local districts.Gothold said while the education system needs to figure out a way to hold students harmless for learning challenges, moving away from a traditional grading system could have long-term impacts."We are putting our kids at a disadvantage if they're applying for schools nationally," he said. "Not every college, not every institution is even accepting pass/fail or credit/no credit. We've seen this in some of the art schools across the country where kids have applied and have been told they aren't going to recognize those grades."There's also the issue of grant money and scholarships.Gothold said credit/no credit had an impact on some student's finances."Kids that needed a 3.0 to qualify for Cal Grant, for those that were on track to get As and Bs to boost their GPA the second semester of their senior year, some were shut out and not eligible for that funding that they so desperately needed and deserved because of pass-fail credit/no credit," he said.Reporter Adam Racusin asked a handful of the state's largest schools what type of grading system they're using this academic year. All who responded said they were using a traditional A through F system.Back in March, the University of California implemented temporary measures which relax undergraduate admissions requirements for students looking to enroll at UC for fall 2020 and future years as applicable. According to the UC system, these measures will help mitigate some of the extraordinary challenges students and their families face in the midst of the COVID-19 pandemic.A spokesperson for the California State University said they relaxed some undergraduate admissions standards for both newly admitted students and prospective students to account for changes in grading and administration of standardized tests. 3238

SAN DIEGO (KGTV) — Some COVID-19 survivors are noticing a surprising symptom months after their battle with the virus: hair loss.Nikki Privett said she had a mild case of COVID-19 back in April, but several months later, she says her hair started falling out in chunks.“I noticed that more and more was coming out in my hands and then eventually in July it became handfuls,” she told our sister station WRTV in Indianapolis. Dr. Nancy Maly, a physician in dermatology at Sharp Rees-Stealy, said she has seen more patients with complaints about hair loss recently, both from those who have recovered from COVID and those who have not been infected."I definitely have seen more patients lately coming in for hair loss -- with and without having had COVID," Maly said. "From what we know about COVID, there's not really a compelling reason to believe that it's the virus itself but more likely it's this stress-induced kind of hair loss that we know about and see all the time."Doctors believe it’s most likely a condition called telogen effluvium, a type of hair loss that can affect both women and men, and typically starts about three months after a stressful event.It can be triggered by emotional stress like a job loss or the death of a loved one, or by physical stress like a serious illness.Typically, adults shed about 100 hairs a day. But Dr. Maly said when your body is in shock or fighting a disease, there can be backlog on that hair loss.“During that stressful time, your body is prioritizing the most important functions and shedding your hair is not one of them,” she said. “So you end up having that delayed reaction where the hairs that were supposed to fall out during that time fall out later.”There is not a direct treatment for telogen effluvium but this temporary form of hair loss usually resolves itself after about three to six months, she said.There’s also early research showing a different kind of link between hair loss and the virus.Two small studies showed that bald men may be up to 40 percent more at risk of developing a severe case of COVID-19. Scientists theorize it’s because bald men have higher levels of a hormone called adrogen that seems to help the virus enter cells. 2216

SAN DIEGO (KGTV) -- Seven people were displaced following a house fire in Mountain View early Saturday morning, according to San Diego Fire-Rescue.The fire was reported just after 3:30 a.m. on Teak Street near Ocean View Boulevard.

SAN DIEGO (KGTV) — Some University City residents are upset over the city's lethal methods to curb the squirrel population at Nobel Athletic Area park. Many see the park as an escape from the neighborhood's concrete jungle. "One of the joys of being here is to watch the wildlife in the morning-- the rabbits and the squirrels especially," resident, Tracy Benson said. But that began to change once Benson started seeing more green boxes on the ground, similar to water irrigation units.RELATED: Chula Vista seeks public input on future bayfront parks in online survey"There is a hole back here, and in this hole is where the bait is placed. So the idea is the animal eats the bait, comes out, and essentially dies," Benson said. The more of these boxes the animal lover saw, the fewer squirrels she ran into on her walks.10News contacted the City of San Diego to get answers. A spokesman explained that the green apparatus is a "bait box." It helps manage what they call an "overabundant squirrel population."The City's Parks and Recreation Department began using them a few years ago to stop the squirrels from damaging their athletic facilities, landscaping, and eroding the hillside. While Benson understands the need, she believes the method is too cruel.RELATED: San Diego crews work to repair road after massive water main break in North Park"Poison has no place in a public community like this," Benson said. The facility caters to young children and includes an off-leash dog park, both could potentially be affected by the poison nearby. Instead of bait boxes, Benson suggests educating the public by putting up more signs around the park."[The public] are going to have an understanding that if they feed the animals, they actually do more harm than good. And that nature will always balance itself. It's human interaction that creates an imbalance," Benson said.RELATED: Street signs prompt Coronado buzz over possible 'Top Gun' filmingNot always. The city adds, if they do not control the squirrel population in this way, the effects go up the food chain. There will be more coyotes and snakes, animals that would be dangerous to park users. Still, Benson says there must be another way."I think that is upsetting, and I don't think that is the measure that should have been taken to properly control the population of squirrels," Benson added.The city says they periodically place the bait boxes in their parks when needed.  2491
