italian officials say they need more time to determine if a five euro entrance fee dissuaded day trippers from visiting venice. it was an experiment aimed at protecting the city's limited space and public resources. tourists have long flocked to venice for its crisscrossing canals and hand-blown glassware. cbs's dana jacobson traveled to a venetian island and introduces us to an artist who's turning the old world craft into modern art. >> this is not a bad place to work every day. >> no, it's pretty awesome, yeah. ♪ >> reporter: there are few places more picturesque than italy's island of murano. and here along its main canal, roberto beltrami found the perfect place to set up shop. >> it's unique because it's like a historic building. this is a byzantine arch from

the 1100s. >> reporter: this building is headquarters for his company, wave murano glass, where 15 skilled craftspeople create glassware, sculptures, and more. >> what's really exciting about this craft, every day you learn a little bit more about the material. you're able to control it a little bit more, and your muscle memory. it's almost like being an athlete, right? >> reporter: at 33, beltrami is the youngest glass master on the island, a designation that means he's an expert in a trade dating back to the 8th century. and with a workshop that's open to the public, his talent is on full display. [ applause ] beltrami grew up in the industrial city of brescia. the son of two entrepreneurs, he remembers a specific obsession that would eventually shape his life. >> i'd always been a pyro. i burned a couch before i could walk. i would do experiments in the

house, melt tin, plastic, make sculptures with wood, cardboard, wax, anything i could find around the house. i would melt soldering tin for circuits in a pot at home and pour it into plaster molds i had made to sell jewelry at school. >> that's great. so that side was always there? >> yeah. >> reporter: he spent his junior and senior years of high school studying in the u.s., then headed to boston university as a physics major. but before beltrami could graduate, he went to a life-changing exhibition by artist dale chihuly. >> many people cry when they see chihuly exhibitions. i understand. i walked through the exhibition once. then i walked another time through it. then i walked a third time through it, and i came home and started maniacally started looking at youtube videos about glass and researching it, and yeah. >> reporter: so beltrami headed back to italy, specifically murano, where he interned with a glass maker for a year and a half before finding paid work. not an easy undertaking since the craft is usually passed down

within families. >> were you accepted as somebody who wasn't from a glass-blowing family that wanted to learn this craft? >> well, initially i -- i guess i was because i wasn't a threat to anyone, right? i was just a little kid that was in love with glass. then over time, i found it more and more difficult to learn and grow because people are very protective of their craft. i always say my biggest teacher was my science background. >> reporter: wave murano was first based out of a small workshop with beltrami moving the company to this space in 2020. two years later, the european gas shortage hit. >> gas prices since we opened for business has always been around 10,000 euros a month, which for a very small start-up is an insane overhead. then our gas price hiked up to 60,000 euros in one month. >> that can end a business right there. >> yeah, and it would have ended us but the government thankfully helped us. it took a while for the money to get in our bank account, but in the end it arrived.

so we were able to, like, breathe. >> reporter: beltrami's science background also helped, steering him to embrace new technology to help lower operating costs. >> so these are like a new school furnace? >> yeah, these are actually from the united states, from my furnace guru from massachusetts. and together we designed this new format that employs a very efficient technology that's not unheard of, but it's done in a way that makes the furnaces an order of magnitude more efficient than other traditional murano furnaces. >> so it saves you a lot of money? >> yeah, like 80% to 90% gas savings. >> wow. >> reporter: the process of glass-blowing is fascinating to watch. >> okay. >> he's rolling the pipe inside of the molten glass and just like honey, he's picking it up because glass, when it's at that temperature, has the same viscosity as honey. >> reporter: but some of the veteran craftsmen make it look easy, like federico rossi, with

more than 30 years in the trade. >> right now he's always got to wait for this to cool down so he can add another layer of glass on top of it. and this is how we get enough material to make the piece that we want to make. >> reporter: one of the final steps requires a mold. this one is modular and made of wood, a less expensive alternative to the traditional cast iron molds. >> and as he blows, the glass inflates and, of course, takes the shape of the mold. >> this is incredible. >> reporter: the factory is staffed by professionals from around the world, including ana maria perez garrido from spain. >> there are not a lot of women that are glass blowing. what's it like being one of the few? >> well, in murano, it's not too much woman. it's a long tradition, and i understand the tradition. also we need to change that. >> reporter: one woman at a time. >> okay. >> so if i get hooked and i want a job --

>> well, yeah, we can work that out. >> we'll see how i do? >> this is your job interview. >> reporter: he wasn't kidding. a lesson and interview all rolled into one. >> what we do is we even out. see how the shape of the glass is evening out? >> yeah. >> and when it's nice and even, i'm going to start a bubble inside of the glass. there we go. you can put that back in the bucket. >> okay. >> and now i'm going to blow a bubble inside of the glass. >> reporter: the glass is heated some more. then a neckline is formed. >> see how that's cracking the glass from thermal shock? and now you're just going to use this to tap the pipe here. >> just tap? >> yeah. harder like this, yeah. >> this is so cool! >> i told you you were going to be hooked. >> oh, my god. >> the last step is going to be removing it, which is often the most critical.

baby to eat their vegetables. physicians say infants should not eat solid food until after 6 months of age. google a.i. even recommended eating, quote, at least one small rock per day, unquote, to increase vitamin and mineral intake. that advice was lifted from an article in the onion, a well-known satirical website. google says it has limited inclusion of satire in humor sites and overviews and removed ones that, for the wrong reason, went viral. a google spokesperson tells cbs news, for health queries, we've always had strong quality and safety guardrails in place, including disclaimers that remind people that it's important to seek out expert advice. but not all of it. cbs news confirmed that some health misinformation persists on the tool. queries about introducing solid foods to infants under 6 months old still returned tips in late june when we tested it. searches on the health benefits

of dubious wellness trends like detoxes or drinking raw milk included debunked claims. despite the quirks and outright errors, many health care leaders remain optimistic about a.i. chatbots. >> in the long run, i think these technologies are going to do us a lot of them. >> reporter: one of them is this chief data scientist at stanford health care. >> when google search came around, everyone was panicking that patients will self-diagnose, and all hell will break loose. didn't happen. same thing. we'll go through that phase with chatbots that, yes, of course, the new ones that are not fully formed will make mistakes, and a couple of them will be bad. but by and large, having information at your disposal whether there's no other option is a good thing. >> hi, i'm sarah. >> reporter: this is the world health organization's chatbot, sarah. sarah pulls information from the world health organization and trusted partners. >> how can i lower my risk of heart attack? >> focus on a balanced diet, regular exercise, managing

stress. >> reporter: advocates of chatbots are quick to say that physicians, like bots, can make mistakes. estimates vary, but a 2022 study by the department of health and human services found up to 2% of emergency room patients each year may have suffered harm from a misdiagnosis. with the right design and oversight, a.i. chatbots might one day give better medical advice and reach more patients in need. but if you are turning to an a.i. chatbot for health advice today, note the warning that comes with google's version. info quality may vary. major garrett,
