A woman was caught on camera removing some of them this afternoon. Im saving the safety of a lot of students.

Reporter coulter is a right wing pundit and best selling author. Develin said his liberal classmates can learn from her point of view. It just becomes a Power Dynamics game. We can no longer have rational discussions and debates with one another, and thats all we are trying to do with having ann coulter come back to berkeley. Reporter coulter canceled an event two years ago due to security concerns. While its clear some students dont want her at cal, others say they are willing to listen. I can definitely understand how some communities on the campus might feel offended or scared by having her here. And i sympathize with those communities.

Reporter Berkeley College republicans say they will put up more fliers here tomorrow. They expect they will be promptly removed. Protests are expected here next week.

You may not know, but people with chronic pain are lining iny pay derely for the hope of relief. Anything to relieve the pain, but that also leads to false promises. Spent the past six months investigating claims by a south bay clinic using stem cells to fix chronic pain. Our consumer investigator chris chmura talked to patients, doctors and regulators and really theres a lot of concern. Not just in the bay area, but around the country. Certainly, yeah. And these are tiny microscopic cells that potentially huge all at the same time. Researchers are in labs every single day trying to figure out if stem cells can regenerate cartilage or muscle. Thats not proven, and yet many clinics are already offering treatments. Some say theyre too early, too risky, and too expensive. I have all kinds of stuff here. Marilyn is in pain. I wanted to fix all that so i didnt feel like i was 0 years old. This inquichiropractors ad to her. Relief using stem cells. 80 chance of success. That sounds really good. I signed that contract for almost 13,000. She got four shots, two in her hips, two in her shoulders for her 13 grand. But . I got nothing for my money. I got nothing. Marilyns sister barbara got the stem cell treatment, too. Same clinic, same money, same result. I cannot tell you any relief that i received. Experts we talked to arent surprised. What we would call bogus therapy. All the scientists. I would be very cautious about this. Doctors. Theres no proof they help. And regulators we interviewed voiced the same concerns. But theyre using it to promise people cures which we dont actually know they can deliver. Look at this advanced Health Center ad. The chiropractors say dont mask your pain, fix it with stem cells. Knee pain, hip pain, arthritis, shoulder pain. Is stem cell treatment approved for knee pain . No. Hip pain . No. Arthritis . No. Shoulder pain . No. So what is it approved for . Its approved for transplants and thenhr other conditions, two of them quite rare. At u. C. Berkeley, no bell prize winning biologist randy cheick man says its years away and not even guaranteed. Stem cell injections that are part of a rlk sterd Clinical Trial might be okay, but in a regular cairo practice und no. And yet lots of people are getting the treatment. We asked advanced Health Center to review barbara and marilyns cases and tell us what was in their shots. It declined to participate in our story. Who knows whats being injected. May not be any kind of stem cell at all. The doctor questions whether they are giving People Living stem cells. The patient has no way of knowing. Do you have any idea what they actually injected into you . No. Marilyns paperwork says she was injected with a product called sure force. Its made fro donated pla ten t placental tissue. The doctors we talkeskepcal. By the time placenta is processed and injected, any stem cells are still alive. We tried to get details and a sample from the manufacturer. But the company did not return our calls. Is pain keeping you up at night . Stem cell clinics are popping up all over. The food and Drug Administration estimates 700 nationwide. They just produced this cautionary video about unapproved stem cell treatment. None are proven to work to treat these conditions, worse, some may cause harm. Why doesnt the fda shut down stem cell clinics and their suppliers . Because they straddle a gray area, according to the fda. So buyer beware, especially since insurance doesnt cover unapproved stem cell injections. People are paying money out of pocket and unfortunately if they dont work, even if they arent necessarily harmed physically, they can be harmed very much financially. The money can be big. Online medical consultants are promoting stem cells to chiropractors. One in arizona touts an easy new revenue stream. And we implement and manage your entire regenerative program. Another in florida posts testimonials from chiropractors on youtube. Hi, im dr. Brian coil in san jose, california. Including dr. Coyle of advanced Health Center in san jose, the clinic that treated marilyn and barbara. Were going to definitely double our practice and easily make a Million Dollars more next year. We wanted to talk with dr. Coyle or anyone else at advanced Health Center. They never responded to our emails. So we went in person. They declined to speak with us. Thats the same response we got from everyone else we contacted in the stem cell industry. The doctors, manufacturers, suppliers, consultants. Silence. The public needs to know. Marilyn feels shes being ignored, too. So shes filed complaints with the state. They get your hopes up and you think, oh, my god, this is the fountain of youth. You know . Its going to fix all my problems. And then youre so crushed when it doesnt do anything for you. And they got your money. The state board that oversees chiropractors tells us they are looking into the industry. Also chiropractors are not licensed to do injections. What happened in marilyn and barbaras case . A medical doctor they hadnt previously met was hired by the clinic to give them the shot. That doctor also declined to participate in our story. Do you have a stem cell story to tell . We want to hear from you and try to talk to your doctor. Scan this 2 r code to contact us or use the smartphone to call us, 888996tips. Back to you guys. Fascinating story. Theyre spending a lot of money. And they have the physical pain. The hope. Mental and emotional pain. Very good story. Jeff is here now to talk about our weather as we friday. Today was a wacky day. Well start with more of that cloud cover and also some areas of drizzle as you start off on that friday morning commute. And then eventually well get some sunshine in here for you. Le b into the things about at cooler air that moved in, little bit of drizzle as well and the cloud cover helped to stir up the atmosphere enough that we have good air quality right now. And we do think good air quality as we move into tomorrow. Thats quite a bit of relief after some of those smoke particles we had earlier in the week. And also just those stagnant conditions. So just know youll breathe a little bit easier as we hit your friday forecast. For the morning we begin with that cloud cover. Chilly 40s here for the south bay peninsula and the trivalley. So youll need the jacket. And probably not the sunglasses as you start off here, even the possibility of some drizzle. I think the best chance, once again here in san francisco, and right through the north bay. This also goes for anyone at the immediate coast line. A closer look at that cloud cover and youll see while were socked in for the Morning Hours with that drizzle, once we hit 1 00 it tries to break up. I still think well have some high overcast still at 1 00 p. M. Eventually by 3 00 p. M. We should start to get some sunshine in here, but its going to be that short window just because the sunset is coming a lot earlier in the 5 00 hour. Nonetheless well see brief clearing as we hit friday afternoon, right into the evening. Temperatures still in the jacket weather territory for the afternoon. At least for some of us. Down here in the south bay 66 in morgan hill. 65 los gatos, 66 in milpitas. Closer to the bay, 63 in hayward. 64 in fremont. Right back to antioch 69. Over to the peninsula, 62 in redwood city. San francisco, 50s right near the ocean from the outer sunset to the marina. And 62 in the mission. And for the north bay going up to wine country on your friday, maybe a threeday weekend, 69 in napa, 66 sonoma, 66 as well in right . Like fall outside,d refreshing, little bit crisp as well. This g is High Pressure building in, and thats going to take all it, and shove it way back to the north as the High Pressure noses its way in. It will warm us up. Youll see in san francisco, we go back to 67 once we hit sunday and were dry over the next seven days. Inland valleys, i have you also back in the 70s this weekend. Notice you get some morning fog back for saturday morning. Sun for the afternoon. Sunday looks really great. 76 degrees. And i think by next wednesday weve been talking about these updated rain chances. It will be frustrating. Well be sandwiched between two different storms, one to the north, one to the south. So no big rain chances at this point. I dont know about you guys, bu weekend. Were almost there. Friday is tomorrow. We are. Thanks, jeff.

Stanford doctors using Cutting Edge Technology to save the life of a little boy. This is incredible. Ari had a rare and lifethreatening tumor growing at the base of his brain. He needed a special surgery to remove it, but at just two years old, his doctors say it had never been performed on a patient so young. So a team at stanford had a groundbreaking approach. Go through aris nose to reach and remove the tumor. The team spent hours practicing on a virtual o. R. And using a 3d printed replica of aris skull. The 16hour surgery was a success, and ari is doing great. His parents say their little superhero isk. He ugly incident in the nfl. Stay with us. We made usaa insurance for members like kate.

Just endangering the other team. He knows that. Its inexcusable. He knows that. I hope he does now. Its tough. Myles garrett did apologize just a few moments ago in the locker room to the media.
