SAN DIEGO (KGTV) — A new cancer screening method is promising to eliminate the need for painful biopsies and greatly reduce the cost of the procedure.It's part of a line of research known as liquid biopsy and the latest advancement is being ramped up for mass production by an entrepreneurial couple in Torrey Pines at the research firm, BioFluidica.  Among billions of blood cells, the company has developed a chip capable of finding a single abnormal cell afflicted with cancer or other diseases."It is probably the most sophisticated injection molding piece in this world," said molecular biologist Rolf Muller, as he holds up a thin, plastic chip about two inches square.First developed by researchers in North Carolina, the chip is injected with a small blood sample which can contain billions of individual cells. The blood passes through 150 tiny tunnels within the chip which are coated with antibodies. Those antibodies do their natural work of isolating the abnormal cells.Researchers can then identify them for any possible threat and treatment.The Mullers say the screenings have the potential to dramatically increase survival rates for cancer patients. And to eliminate the need for the often painful biopsies currently in use.They also envision the test becoming a normal part of standard blood screenings. The chip is currently in clinical trials. It could be available for general use within two years. 1432

SAN DIEGO (KGTV) — A man was arrested Thursday after attacking police with railroad spikes and rocks in a Barrio Logan train yard, police said.San Diego Police were called to the BNSF Railway Yard along Harbor Drive around 10 a.m. to reports of a trespasser. Officers arrived to find a man who had armed himself with a stick and railroad spikes, police said.The suspect reportedly threw the spike at officers and fled under a rail car, refusing to come out. The man also threatened to kill a police K-9 on scene, SDPD added.Police created "decision making space" and tried to talk the suspect into surrendering. After those efforts failed, officers used shotgun beanbags, pepper balls, and eventually a K-9 officer to get the man to surrender. He was pulled from under the railcar and taken to a nearby hospital for treatment of injuries, including dog bites, police confirmed.No officers were injured during the event. 927

SAN DIEGO (KGTV) - A San Carlos resident is sharing video of what he believes is a large mountain lion running across a busy street in his neighborhood.Mike Johanning was driving home from dinner at 11 p.m. when his dash cam captured the animal.The incident happened on Navajo Road near the Mission Trails Golf Course and Cowles Mountain trailhead.The possible mountain lion was as wide as his car, Johanning told 10News.Johanning has lived or worked in San Carlos since 1997 and said he had never seen a mountain lion in the area.Wildlife Research Institute researcher David Bittner saw Johanning’s video and confirmed it was likely a mountain lion.  Bittner is leading a project that has set up cameras throughout the county looking for mountain lions.  He says a sighting in San Carlos is rare.Bittner says he may be a juvenile striking out on his own hunting for deer. "Usually they go back home after a few days," said Bittner.  966

SAN DIEGO (KGTV) -- A new program at three San Diego-area community colleges is hoping to bridge the gap between minority students and their teachers.The Deber Program at Mesa, Southwestern, and City colleges hopes to encourage more bilingual people to become teachers."We don't have enough people of color in the classrooms," said Laurie Lorence, Teacher Education Director at Mesa College.The program will help recruit bilingual college students who want to become teachers. It will assist them throughout their college careers with applications, transfers, testing, and mentoring."We're hoping a lot of students want to give back to their community and reach down to give them a hand up," said Lorence.Right now, there's a wide disparity between the number of minority teachers and students of color in San Diego.According to the San Diego County Office of Education, 69% of students in local schools are students of color. But only 26.3% of teachers identify themselves as teachers of color. Bridging that gap can help minority students succeed."A student can look up at the teacher and say, 'Wow, if that person's done it, maybe I can too,'" said Lorence.For Karina Vidro, one of the students already in the Deber Program, the help it provides is vital."I know where I want to be, but I don't know all the details in between," she said. "So knowing that someone is going to be there to support me in that direction is fantastic."The Deber Program is funded through a five-year grant from San Diego State University. Lorence says the first few years will focus on Hispanic and LatinX students. They plan to expand to other minority groups after that. 1662
