SAN DIEGO (CNS) - A United Airlines flight scheduled to take off from San Diego International Airport was diverted from the runway just before departure Friday due to an undisclosed mechanical issue with one of the plane's engines.Flight 478 was scheduled to take off for Denver shortly before noon, but was recalled while on the airport's taxiway. The plane was safely escorted back to the airport's terminal and the issue occurred at low speed, according to United.``The aircraft safely returned to the gate and customers deplaned normally,'' a United spokesperson said in a statement. ``We are making arrangements to get our customers to their final destination as soon as possible.''Roughly 120 passengers were aboard the flight. United and San Diego International did not disclose the plane's model, and information on a future flight to Denver was not immediately available. 888

SAN DIEGO (CNS) - An international team of scientists, led by biologists at the University of California San Diego, has synthetically engineered mosquitoes that halt the transmission of the dengue virus, the university announced Thursday.Scientists at UC San Diego Associate Professor Omar Akbari's lab worked with Vanderbilt University Medical Center to identify a human antibody for dengue suppression. The broad-spectrum antibody stops the transmission of all four known types of the fever, compared to previous experiments, which have been able to limit single strains.The team then designed the antibody "cargo" to be synthetically expressed in the dengue-spreading Aedes aegypti mosquitoes.RELATED: UC San Diego study finds solutions for loneliness"Once the female mosquito takes in blood, the antibody is activated and expressed -- that's the trigger," Akbari said. "The antibody is able to hinder the replication of the virus and prevent its dissemination throughout the mosquito, which then prevents its transmission to humans. It's a powerful approach."Akbari works in the Division of Biological Sciences and is a member of the Tata Institute for Genetics and Society.These lab-engineers mosquitoes could be paired with a dissemination system, making it capable of spreading the antibody throughout wild disease- transmitting mosquitoes, Akbari said.Dengue fever is a virus that poses a severe risk to children and older adults in tropical regions in Asia and Latin America. There are an estimated 390 million infections every year, around 500,000 of which lead to Severe Dengue, and 25,000 people die of the disease every year.RELATED: UCSD Health, San Diego Zoo Safari Park team up to save gorilla's eyesightThe Pan American Health Organization recently reported the highest number of dengue cases ever recorded in the Americas. Infecting those with compromised immune systems, dengue victims suffer flu-like symptoms, including severe fevers and rashes. Serious cases can include life-threatening bleeding. No specific treatment exists and thus, prevention and control depend on measures that stop the spread of the virus.This development could go a long way toward limiting the disease's transmission."It is fascinating that we now can transfer genes from the human immune system to confer immunity to mosquitoes," said coauthor of the paper, Dr. James Crowe, Jr., director of the Vanderbilt Vaccine Center at Vanderbilt University Medical Center in Nashville, Tenn. "This work opens up a whole new field of biotechnology possibilities to interrupt mosquito-borne diseases of man."Akbari's lab is now in the early stages of testing methods to simultaneously neutralize mosquitoes against dengue and a suite of other viruses such as Zika, yellow fever and chikungunya. 2789

SAN DIEGO (CNS) - National University announced Wednesday its Board of Trustees approved a plan to reduce the cost of attendance through tuition cuts of up to 25% for full-time students and adding scholarships that will make enrollment nearly free for Pell Grant eligible students.The actions -- made possible through a 2019 gift to the La Jolla university's reserve fund by philanthropist T. Denny Sanford -- "reflect a heightened sense of urgency to reduce costs amid the COVID-19 pandemic and resulting, unprecedented U.S job losses," according to a university statement.The university, which was founded in 1971, said it has committed to:-- doubling the award amount of existing scholarships, enabling Pell- eligible students to earn a bachelor's degree for close to no cost-- creating "opportunity scholarships," valued at million total, for displaced workers and working adults in need of financial support to restart their college studies-- launching a "fast-track" scholarship which rewards students with a fourth tuition-free course for every three courses completed within a six-month period-- investing in additional student support services designed to remove barriers to degree completion"In a moment of enormous economic hardship, open-access universities have a responsibility to make dramatic changes to not only reduce costs, but to evolve their academic offerings to ensure tight coupling with the demands of the labor market," said David Andrews, president of National University. "Our trustees have challenged us to take immediate next steps to ensure that we substantially reduce tuition while simultaneously improving student experience and outcomes."Michael R. Cunningham, chancellor of the National University System, a network of nonprofit education institutions and initiatives that includes National University, said: "Working adults who are first to lose their jobs in a recession are often the last hired in an upswing."As we mark fifty years of serving working adults and veterans and enter this new era for higher education and our economy, this new tuition strategy will enable us to significantly expand access to working adults in need of opportunity today." 2204

SAN DIEGO (CNS) - Jurors reached a verdict Tuesday in the trial of a Navy SEAL accused of fatally stabbing a wounded teenage ISIS fighter in the neck, shooting at numerous Iraqi civilians and threatening fellow SEALs to keep them from reporting him.Jurors found Special Operations Chief Edward Gallagher not guilty on six out of seven charges, including not guilty verdicts for premeditated murder, two charges of attempted premeditated murder, obstruction of justice, retaliation, and willful discharge of a weapon. Jurors did find him guilty of wrongfully posing for a photo with the teen's body. That guilty charge carries a possible sentence up to four months. 673

SAN DIEGO (CNS) - As part of its reopening plan amid the coronavirus pandemic, the San Diego Unified School District allowed some students facing severe challenges to return to in-person learning today, but a timeline for the district to reopen fully remains unclear.Phase 1 of the district's plan to reopen is to allow elementary school students ``who have been uniquely identified by their teachers as experiencing learning loss'' to have limited in-person appointments.Participation is voluntary and students who participate in the sessions will continue to receive online learning.On Tuesday, Lafayette Elementary School in the Clairemont Mesa neighborhood invited back 25 of the 27 students who were asked to return to in- person instruction -- many of whom are part of a deaf and hard-of-hearing program at the school.The district's Phase 1 includes a mandate for less than 20% capacity for rooms and for schools, half days to avoid groups eating at schools and a six-foot distancing everywhere on school grounds -- barriers or no barriers.This summer, San Diego Unified adopted standards developed in consultation with experts from UC San Diego. As a result, conditions for the district's reopening local schools are considerably stricter than state standards, and much stricter than various other school districts in the region that have opened for in-person learning.According to the district, all California Department of Public Health criteria has been met to a level where limited in-person classes are possible.The next stage will be when both state and county data fit the district's stricter metrics. That date is anyone's guess, leading to some frustration from parents.Parents and guardians in the ``Reopen SDUSD'' group said the district's current reopening plan was ``riddled with vague language that is a far cry from a comprehensive plan that families have been asking for.''With the criteria SDUSD has in place, it could be weeks or months until in-person school becomes more widely used. Even then, it's not a guarantee school will head back as soon as the numbers fit.In the Chula Vista Elementary School District, a push from Superintendent Francisco Escobedo to reopen the state's largest elementary school district for in person instruction on Oct. 26 was met with significant backlash from the Chula Vista Educators union.Susan Skala, the union representative, said collective action and possibly even a strike was on the table unless Escobedo and the administration backed down. Chula Vista is seeing higher-than-average numbers of COVID-19 cases and hospitalizations, and after parents, guardians and educators spoke at a town hall last week, the district relented, moving the new start date to sometime ``near the end of the year.''That example leaves San Diego Unified with a difficult path to walk during the continuing pandemic with public safety, education, unions and families all playing a part.The district has made efforts to make schools and sites safe, purchasing million in personal protective equipment and other safety equipment. It has also received some 200,000 masks in child and adult sizes from the state, along with 14,000 bottles of hand sanitizer. 3211
