SAN DIEGO (CNS) - Two researchers, including one from the Scripps Institution of Oceanography at UC San Diego, are in Antarctica in an effort to uncover the planet's oldest ice.The research trip is part of a cordial international race to find the ice, which will give geologists and climate scientists new insight into Earth's climate history. Scripps paleoclimatologist Jeff Severinghaus and University of Minnesota-Deluth geologist John Goodge arrived this month at an ice-drilling outpost at McMurdo Station, Antarctica.In October, Severinghaus and researchers at Princeton University published a study in the journal Nature analyzing a two-million-year-old ice core. However, that core was incomplete in its historical portrait of ancient air. According to Severinghaus' ice dating lab, the planet's oldest ice is roughly 2.7 million years old.RELATED: San Diego Zoo welcomes second rhino born via artificial inseminationSeaWorld frees whale tangled in 900 feet of rope off La JollaSan Diegans can fly over rush-hour traffic with FLOAT air service"That core ... was all broken up," Severinghaus said of the Princeton study. "It's like in archaeology when you find pieces of broken pottery you're trying to put back together."The two researchers are attempting to expedite the conventional ice drilling process, which currently takes roughly five years to dig two miles to the Antarctic ice shelf's deepest point. They believe their 50-ton drill could secure a 50-meter ice core with a full timeline of the continent's geologic development. Eventually, it could be used to dig to the continent's bedrock, which dates back 3 billion years.In addition to each other, geologists and climate scientists in the southern hemisphere are in a race against nature, as climate change continues to melt Antarctic ice and cause sea levels to rise, particularly on the continent's western edge, according to Goodge."The bigger question is what's happening in East Antarctica because there's a lot more sea level rise potential if it begins to melt as well," he said. "So we really need to understand what those conditions are."Once collected, the researchers will pack the ice samples in boxes until January, when the Antarctic sea ice thaws and the samples can be shipped to Port Hueneme in Ventura County. They will then be transported to the National Science Foundation's Ice Core Facility in Lakewood, Colorado, for study in late spring. 2439
SAN DIEGO (KGTV) — A jury has reached a verdict in the trial of a woman accused of drunkenly dragging her co-worker with her car before fatally running him over in Kearny Mesa.Latisha Ingram, 33, was convicted of second-degree murder, gross vehicular manslaughter while intoxicated, hit-and-run and drunken driving in the death of 25- year-old Ha Minh Ta.Prosecutors say Ingram, Ta, and a group of co-workers went out for drinks on Convoy Street last June, when Ingram tried to driver herself home. Ta tried to stop her, eventually grabbing the door of her car.

SAN DIEGO (KGTV) — A 91-year-old La Jolla resident is the first confirmed case of West Nile virus of the year in the county.The man was hospitalized with encephalitis in September but was confirmed Thursday to have the virus by the California Department of Public Health.He has been discharged from the hospital and is recovering, according to the county.RELATED: Community gives gift of mobility to young West Nile survivorThe man had not traveled outside of the county within the month prior to becoming ill, leading officials to believe the mosquito bite was local.Mosquitos trapped near the man's home tested negative for West Nile by the county Department of Environmental Health. Nearby residents have still been notified of the case.Last year, there were two confirmed cases of West Nile in the county, a drastic decrease from the 22 cases reported in 2016, in which two people died. So far this year, there have been 132 cases in California, including two deaths.RELATED: Mosquitoes in Santee test positive for West Nile virusMany of those infected with West Nile do not experience symptoms, the county says. About two out of 10 cases may suffer a headache, fever, nausea, fatigue, skin rash or swollen glands.The county reminds residents to protect themselves from mosquitos bites by wearing long sleeves and and pants, and using repellent when outdoors. Residents should also prevent breeding by dumping standing water and using mosquito fish if needed. 1486
SAN DIEGO (CNS) -- UC San Diego denounced an Instagram account claiming an affiliation with the university that posted "hateful, racist content" on its page, while a similar investigation was underway at the University of San Diego.On Sunday night, UCSD officials were made aware of the page, which featured several racist posts and represented a connection with the university."We firmly denounce what was shared on this account," the school wrote in a Monday afternoon Twitter statement, "and condemn all forms of racism and hate."UCSD said similar posts were seen on another account, which apparently claimed affiliations with a different university.RELATED: USD investigating white supremacist Instagram accounts that claim ties to schoolThough the other university was not identified in UCSD's statement, the University of San Diego posted a statement last weekend indicating the school was aware "that abhorrent and hateful Instagram accounts, claiming ties to USD, have been used to post white supremacy propaganda."In a statement, USD said the content of the accounts "tears at the very fabric of who we are as a Catholic university and the values we hold dear."The school says it has initiated an investigation into the posts and asked Instagram to take the pages down, along with any other affiliated accounts.USD officials said anyone with information regarding the accounts' creator should contact Dr. Donald Goodwin at deanofstudents@sandiego.edu."Hate speech and actions directed at intimidating or harassing any members of our campus community have no place at USD and cannot be tolerated," the school said.UCSD says its Office for the Prevention of Harassment and Discrimination -- which provides assistance to students, faculty and staff regarding reports of bias, harassment and discrimination -- is working with the school's chief information security officer to investigate the account.Anyone with information regarding the account's creator was asked to contact the Office for the Prevention of Harassment and Discrimination at OPHD@ucsd.edu."If found that UC San Diego community members are involved, they will be held accountable," the statement said. "UC San Diego stands with our Black community members and firmly against all forms of racism and hate. We encourage our community to actively counter racist speech and to be an ally and advocate to any group that is harmed, by upholding UC San Diego's Principles of Community and our commitment to each other as Tritons." 2504
SAN DIEGO (KGTV) - 36 students reportedly felt sick at a Bay Terraces elementary school due to possible construction-related fumes, according to the San Diego Fire Department.San Diego Fire-Rescue crews responded to Zamorano Fine Arts Academy around 10:30 a.m. following the reports of students feeling ill. Crews said the kids complained of not feeling well and were being held in the school's cafeteria.An ambulance brought one child to a nearby hospital, SDFD said. Around 11:45 a.m. SDFD began releasing students who were being held in the cafeteria. A nearby construction site was in the process of pouring resin when the smell caused some children to start feeling sick, according to San Diego Unified School District. The resin is non-toxic, but fire crews were called to check out the students. 835
