first indian-american woman to run on a major political party's presidential ticket. political analysts say harris will likely motivate at least one group of voters. >> women, especially older women are going to be very drawn to having her as part of this ticket. >> former president barack obama says joe biden mailed his decision while president trump called harris, quote, nasty and just about the most liberal person in the u.s. senate. california has shaped kamala harris' politics almost as much as california has shaped her. liz kreutz is here with her bay area background. hi, liz. >> yeah, kamala harris is well-known to all of us here thin bay area. of course often called the daughter of oakland she has a steep history in california politics. so as the choice to pick her as vp may come as a surprise to some a look at her past shows how her political trajectory has in many ways been leading to this moment. born in oakland in 1964.

contributor phil mater for his perspective so stay tuned for that. now the potential link between covid-19 and vaping. abc 7 news reporter david louie tonight looks at some eye opening numbers. >> reporter: the research involved a survey with 2,400 teenagers and adults. it includes those who vape, smoke cigarettes or both along with nonusers. those who ever used cigarettes were five times more likely to test positive for covid-19 and seven times greater if they ever used both e-cigarettes and cigarettes. researchers said what surprised them most was the rate of a positive covid-19 diagnosis was 6.8 times greater if a young person used both in the past 30 days. principle investigator dr.

fe felcher explained what could be the cause. >> there's some question whether there is coronavirus that the virus itself is being carried in that big plume of aerosol that you see. >> reporter: she also cited the impact of lung function by nicotine and e-cigarettes. she tested positive for covid-19 after club 'ing spain last march. >> i was so lucky i had such a mild case. if i'd been vaping it might have been a different story. i think so many people especially my age just feel so invincible. >> reporter: an advocacy group for vaping products disputes the findings pointing out this study found no association between having vaped exclusively during the prior 30 days and reporting a positive covid test. david louie, abc 7 news. >> the study also found that blacks, hispanics and multiracial surveyed participants were almost twice

as likely to have covid-19 symptoms. a reversal from the school district means teachers can work from home. teachers can now choose whether they want to rurp eturn to scho to teach virtually. a challenge for many cities is finding funding for online learning. as lyanne melendez explains salesforce is now doing something about that. >> reporter: he's financially supporting the way san francisco public schools can reimagine education through the pandemic. >> and we're committed to help our schools reimagine the future of learning that is equitable and safe from anywhere. >> reporter: they'll also invest in programs for san francisco unified that can improve student outcomes. students learn by doing rather than just sitting in the classroom learning the material. >> they can go deeper into

>> reporter: the needs and wants of schools throughout the years have changed. in 2013 he gave san francisco unified $2.7 million to buy 750 tablets distributed throughout their 13 middle schools. each principal also received $100,000 to spend in those areas most in need. today the donation is $9 million, and those middle school principals will each receive $200,000. oakland unified will also receive financial support from salesforce. oakland unified will also get $9 million to support the challenges they'll face during the pandemic. >> realizing everything we do we have to reimagine and re-create it to figure out how to make it work and succeed virtually. >> reporter: special attention in oakland will be given to newcombers such as unaccompanied

immigrant youth, refugees and asylum seekers. researchers here in the bay area have made a discovery they say could help protect yourself from covid-19. the key is something which you may actually already be doing. since the covid-19 outbreak experts have asked us to wear face masks to protect against spreading the virus to others. but now researchers at ucsf have evidence that may wearing a mask you might be guarding your own health as well. >> we have learned over the last couple of months there's a huge advantage of masking which it protects you. >> reporter: dr. monica gandhi she and her colleagues compared groups practicing masking with others with the behavior. the conclusion is not just masks can help prevent transmission but what happens when they don't. >> even if you happen to get a couple of viral particles into a mask you may get infected but you're very likely to have mild

or no symptoms at all. so it reduces the severity of disease to wear a mask. >> first it's important to understand researchers have looked at virus outcomes in human and animal models for decades. and in the case of many viruses how much you ingest matters. a smaller viral load can potentially give your body a big head start, time to fight off the infection and most importantly build immunity. >> if you're unlikely to get sick. you're just going to have mild symptoms or be asymptomatic, no symptoms. >> the question now what could that mean for the population at large if we all wear masks? the vaccine is still key obviously. researchers believe less severe disease now could drive the overall population towards what's known as herd immunity. the tipping point when there are not enough carriers left for the virus to spread. >> we may start to get immunity from this virus while we're waiting for a vaccine. >> an outcome easily worth the

inconvenience of covering up. researchers say a greater prupiration of new covid-19 cases have been mild or even asymptomatic but more data is needed to see if that's due to higher rates of people wearing masks. surveillance video captures a man unloading a bag on a doorstep. inside of all the makings of what some say are a voodoo curse. it's all about turning your android phone into a mini seismometer. and if fans can't come to and if fans can't come to see the drag queens then the - [narrator] did you just reward yourself for spending a perfectly reasonable amount of time on the couch with tacos from grubhub? rewarded! get a free delivery perk when you order. - [group] grubhub.

parking issue. >> the people living here as either tenants or owners were using the visitors parking spots as a residential spot. >> reporter: he even collaborated with his neighbors posting these signs which have helped cleared vehicles out. san jose police tell me they are not aware of any similar incidents and that no suspects have been identified. he has this message for whoever the man in the video is. >> all i'm trying to do is make the community a better place. i'd rather the person, you know, approach me and talk to me instead of putting my family in harm and affecting them. >> reporter: in san jose, dion lim, abc 7 news. latin-american studies professors dion spoke with say while some of the items can be used in religious offerings the bloody animal parts should be seen as disturbing. well, your cellphone may soon become an earthquake sensor. the state teamed up with google and usgs to create an early warning system for android
