the fight to be the world's most valuable company heats up, after apple announces new ai tools on its devices. and how long can you survive without your smartphone? we put a group of british teenagers to the test. hello and welcome to business today. i'm arunoday mukharji. apple shares have surged to a record high, after it unveiled new ai tools. apple is now a $3.18 trillion dollar company, just behind microsoft which remains the world's most valuable company. from new york, erin delmore has the details. investors have been waiting for months to see how apple would

embrace ai and propelled many other tech trains to big market gains. on monday they got their answer, a partnership with openai. and chatgpt powers for cre plus some enhancements like proof reading and writing help and ai generated images in the mode geez. and even though the news came on monday, it was not until tuesday that the market rewarded apple's efforts. on monday apple she was actually closed down around 2%. but on tuesday, shares ended the day up tuesday, shares ended the day up 5% to around $203 per share. that is a new record high for apple, betterthan that is a new record high for apple, better than december. those new ai tools are only available on newer models of apple products at the iis pro the older series will do it neither will the base model iis neither will the base model i15 and i've max will need to have apple preparatory and one chip or newer. and that if suitors are betting that consumers will upgrade their devices to take

advantage of the new tools which would lead into mower sales for apple. staying with al investments. shares in oracle havejumped by as much as 11 percent after it announced cloud deals with google and openai. it comes despite the software giant's fourth quarter results fell short of expectations. oracle is trying to catch up with cloud giants like microsoft who are seeing rapid growth as a result of tie ups with openai. policymakers at the us central bank are in session to decide on the cost of borrowing. the fed is expected to hold interest rates steady. inflation data is also due, but could that sway the fed's rate cut decision? let's bring in david chao, global market strategist at invesco. we have seen some depreciating pressures in cases like japan with the currency given the interest rate differential and certainly all asian central banks are waiting with baited

breath for the fed to cut rates. at the same time, i think that asian economies are on a much better suited this time around with their external buffers that can withstand some of this pressure, but certainly, rates are too high in asia in places like korea and thailand and they should have been cut already. we are countin: have been cut already. we are counting down _ have been cut already. we are counting down to _ have been cut already. we are counting down to the - have been cut already. we are counting down to the us - counting down to the us presidential elections and i want to get your thoughts. how do you think given the political scenario there, how are the politics likely to play on the economics going forward? from the market perspective, we have done crushed analysis and there is no rhyme or reason in terms if a democratic president or republican president is in the white house, what that means for asian markets. asian markets have largely shrugged this off. so let me say that heading into the presidential election, there could be a few jitters with asian markets, but we think it is mostly a

near—term phenomenon. certainly president trump has previously said that he is going to increase tariffs against places like china and also other places around the world. that certainly would not be conducive to trade. whereas, joe biden has shown that he is more strategic when it comes to trading partners. so i think it is something that we are keeping a close eye on, but we are not worried from a long—term perspective in terms of the impact it will happen asian markets. let's take a look at airlines and travel trends. a number of countries have been easing visa rules, to try and boost numbers, but that hasn't quite panned out as hoped. international trips are up in asia, but they're still below pre—pandemic levels. for a closer look at summer travel trends in asia, we're joined by aviation expert ellis taylor from consultancy cirium. thank you for your time here.

it's summer time, normally a busy time, but we are still not seeing those numbers, why is that? largely it is because the china usa air routes are still quite constrained from where they were previously. a lot of other markets travel within southeast asia has been strong, but it is notjust asia has been strong, but it is not just the long asia has been strong, but it is notjust the long calls asia has been strong, but it is not just the long calls from china it is also shore house from thailand etc. the tourism traffic pre—covid has not returned. a lot of travellers from china are choosing to holiday domestically or close to their home like japan or south korea instead. i also want to get _ south korea instead. i also want to get thoughts - south korea instead. i also want to get thoughts on i south korea instead. i also l want to get thoughts on your news on the singapore airlines turbulence incident in the conversation that the airline has announced, it's in such a big amount, do you see that as unusual? it big amount, do you see that as unusual? , . , ., unusual? it is an unusual circumstance _ unusual? it is an unusual circumstance and - unusual? it is an unusual circumstance and i - unusual? it is an unusual circumstance and i guess unusual? it is an unusual. circumstance and i guess to give singapore airlines their credit, they have been very proactive in putting out very

generous compensation they are. it is one of those things where if you are in a major incident where there is composition that is there. but what we are seeing this with the larger airlines, they will top the st martin's of that. and singapore airlines has done so previously, they have been quick to give payouts and above the limits. so it could be something we could see more of. we are hearing that turbulence is going to be more common going forward given climate change and other aspects. does this set a precedent, what about other airlines, will they be able to do the same? it goes down to, be able to do the same? it goes down to. as _ be able to do the same? it goes down to, as more _ be able to do the same? it goes down to, as more airlines - be able to do the same? it goes down to, as more airlines come| down to, as more airlines come forward and give very generous payments when there is an incident or accident, it raises the benchmark quite a bake and comes something that globally the interesting works towards. so i think we will see these payments become a little bit more normalised in a bit more

generous compared to what you may have thought of before. really, it will depend on how isolated these incidents are. the opposite may also happen where if severe turbulence happens more often that the airlines may look to actually reduce those payments just because it becomes a bit more part of what is involved in travelling.— part of what is involved in travelling. we will leave it there, thank _ travelling. we will leave it there, thank you - travelling. we will leave it there, thank you for - travelling. we will leave it there, thank you for yourl there, thank you for your thoughts and your time. how long can you last without your smartphone? a few hours? a day? well, we've followed a group of british teenagers to see how they cope without their smartphones for five whole days. the bbc�*s kristian johnsonjoined them, to see how they got on. it's fair to say some teenagers are pretty glued to their phones. 0k, guys, point of no return. thank you. but this group of students are doing the unthinkable, locking them away for almost a week.

you said your goodbye. yes. no tik—tok. no snapchat. no whatsapp. so, guys, these are your. new mobile phone instead that we're using these for the next five days. j the only way of communicating texts and calls. they're going to have to learn a whole new set of skills for the next week to be able to adapt and continue their life as close to what it used to be. but with that mobile phone underpinning most of their activities, it's going to be a real challenge. not being involved in group chats means it's harder for ruby to meet up with friends. some others are struggling to not knowing what's going on, like a group chat. itjust makes me like,

what am i missing out on? usually before i go to bed, i usuallyjust watch like disney plus for like an hour and then just drift off. but since then i've just gone straight to sleep and it's weird. i feel much better the more time goes on, but it becomes a lot easier. will's journey home takes over an hour. this is a service to actually have campus, a tram first, then a bus. so in terms of not having a smartphone, it makes it more difficult because i can't check the timetable. and when they say it's been delayed or something, i could at least ring my dad and ask for a lift, you know? will's mum, allison admits not being able to use family tracking apps like life360 is a hindrance. but she's noticed big changes in her son just three days into the detox. actually, quite nice seeing you without headphones. don't see you that much normally. no. i think it'sjust become the norm. whereas actual social interaction does require you to put these things away and engage a little bit more. five days later, it's the end of term and time to get those smartphones back. maybe i'll put my - phone away in the car and i'll put my phone away, like when i'm _ around my friends.

but in general, like, _ going on to tik—tok everything, i'm still going to do that. like, if anything, i'm - going to do it more now. i think it's been pretty difficult without a smartphone, but i've managed to get through it all right. i'll try and use less tiktok, that's for sure. i know my screen time is quite high on that. judging by their initial reaction, perhaps the students aren't quite ready to give up their smartphones entirely, but the detox might start to slowly change their habits. christian johnson, bbc news. joey "jaws" chestnut has been told he cannotjoin america's premiere hot dog contest after striking a deal with a vegan brand. his removalfrom next month's nathan's hot dog eating contest in new york came after he struck a sponsorship deal with impossible foods a vegan hot dog maker in competition with the nathan's brand. for more food for thought the bbc news website. that's all for us today. but do continue
