LA JOLLA, Calif. (KGTV) - Researchers at UC San Diego have found a way to improve radar technology that can make self-driving cars safer."Our vision is to make self-driving cars much more safer than how we humans drive," says Dinesh Bharadia, an Assistant Professor of Electrical and Computer Engineering at UC San Diego.Bharadia led a team of researchers working on ways to help autonomous vehicles see in bad weather.Currently, he says, self-driving cars rely on LiDAR, a light-based radar system. But it's performance is limited because it uses a low frequency that reflects in bad weather.Bharadia says his team tested wireless radar, which has a higher frequency wavelength and found it can rain and fog.However, the wireless radar's sight range is limited. So Bharadia's team built a system where five wireless radars work together to create a more full "view" of the road."From each radar's vantage point, you see something different," says Bharadia. "Those different things, observed from five different radars, gives you much more detailed aspect ratio of another car (on the road)."Bharadia says the combination of all five radars helps create a 3-D image of other objects on the road. That helps the car's self-driving system figure out how to avoid them."You need to know the exact aspect ratio of the other cars on the road," he says. "Only then can you drive around them if you need to."Bharadia says carmakers like Toyota and Honda have been helping with the research and development. He thinks this new technology could be on the road within 2-3 years."Radars are already out there," he says. "We just need to plug in our software to make the cars more autonomous..."It's a simple technology that can be widely deployed and used to make our roads safer for everyone."Bharadia and his team will present their findings at the Sensys Conference this week.

LAS VEGAS, Nev. — A 33-year-old Las Vegas woman’s dying wish has been fulfilled — she married her boyfriend on Wednesday at Southern Hills Hospital.Alysia began feeling ill about a month ago and thought it might be COVID-19. Instead, she found out that she has leukemia. 278
LARGO, Fla. — While many of us have spent the year wishing things were better, 93-year-old Virgil Sweet has spent the year trying to make it better.Sweet started by giving away his ,200 government stimulus check."I thought, 'I don’t really have a need for that so I’m going to give it to someone who does,'" said Sweet. ABC Action News did a previous story in May to help Sweet get the word out that he was asking people impacted by the pandemic to write him letters about why they needed the money. That story reached people all over the country. Letters poured in from people who needed help and Sweet picked one family to get his check."I found a lady who has two children. One of them is autistic and she has brain cancer so she got the ,200," said Sweet.But Sweet couldn’t stop thinking about the other heartbreaking letters. So he asked others to donate their checks to help. "We did it the old fashioned way, snail mail. We didn’t use email. We didn’t use TikTok or any of that stuff I don’t know anything about," said Sweet.Sweet got donations from California to Pennsylvania, from Alaska to Florida.He raised ,780 for more than 60 families across the country — and he did it from the comfort of his own home using mail as his main source of communication.Sweet says there are still many people in need and he hopes his story shows people you can make a difference no matter what age or what tools you have."You just have to have the passion to help people and you can do it from sitting in your own home," said Sweet.This story was first reported by Wendi Lane at WFTS in Tampa Bay, Florida. 1653
LA JOLLA, Calif. (KGTV) - Scientists at Stemson Therapeutics say they've found a way to create new hair cells that could become a cure for baldness."We're hoping this will be the breakthrough," says Chief Scientific Officer Alexey Terskikh.For a few years, they've been working on a two-part process that turns stem cells into hair follicles. It then implants the follicle cells into the scalp to grow new hair."We have the capability to generate brand new hair follicles," says Stemson CEO Geoff Hamilton.Using iPSC's, stem cells derived from a person's blood or existing cells, Terskikh's team can direct them to become folliculogenic cells, the building blocks of hair.They then put the cells into a microscopic scaffold-like mold made on a 3D printer. The molds are about 1/5 the size of a single strand of hair.RELATED: Here are some options if you start going baldThe scaffolds help keep the cells intact, while also telling the hair which direction to grow. That will help avoid in-grown hair or hair that grows in unnatural ways."Imagine transplanting thousands, or tens of thousands of those into a scalp," says Hamilton.Their technique is different from current hair restoration therapy because it grows new hair cells. Existing methods like Rogaine or Propecia try to revive dead cells or transplant existing cells from one area of the body to another."We're inventing as we go," says Hamilton. "We're making up the path ahead of us as we go."Eventually, they say the cost of the new cells will be similar to the cost of hair transplant surgery now, which can run upwards of ,000.In addition to being a cosmetic solution for people who have gone bald naturally, Hamilton says this could help people who have lost hair due to chemotherapy treatment or from severe burns or injuries.So far, testing has proven successful in mice. Human testing is still years away as the company works towards FDA approval.Stemson's lab is part of the Sanford Burnham Prebys Medical Discovery Institute. 2007
LA MESA, Calif. (KGTV) - A new group formed on social media in response to the destruction of looters and arsonists after Saturday's peaceful protest against injustice.La Mesa Civil Defense is a Facebook group formed Monday by Attorney Scott McMillan. McMIllan was devastated by the chaos Saturday night, "we lost our museum, we lost our art gallery, we lost two of our banks... I did not want to see it [La Mesa] burn to the ground."McMillan said the goal of the page is to communicate how they will protect the town should anything happen in the future, "La Mesa Civil Defense is going to stand in front of the buildings with fire extinguishers and garden hoses and their presence."He said he stood at Nebo Dr. and Lemon Ave. from 7:30 p.m. Saturday night until 6 a.m. guarding local businesses and trying to get looters to stop causing destruction.He said a few people spoke with him.One man explained he was upset about George Floyd's death, McMiIllan said he responded saying, "how does breaking (a neighboring boutique that's been around for 10 years) her windows and stealing her merchandise, honor the memory of George Floyd?"He said the man left and came back to tell McMillan he was right.Those are the conversations he hopes blossom from this group and bring peace to La Mesa.McMillan said he is not asking anyone to use lethal force unless they feel like their life is being threatened.He said they are stepping in to help police and firefighters overwhelmed during these times. 10News reached out to La Mesa PD for a comment and have not heard back. 1571
