tesla's sales improve in the second quarter, sending its stock soaring 10%. with the olympics nearly upon us, we take a look at how technology is transforming the games. hello and welcome to business today. i'm steve lai. we begin in the us, where we've had comments from sticking with the us — shares in tesla surged 10% after billionaire elon musk�*s firm reported better—than—expected vehicle delivery and production numbers in the second quarter. the bbc�*s north america business correspondent michelle fleury has all the details. after going through a slump, tesla may have finally turned a corner thanks to demand for its model three sedan and its model y suv. the company delivered nearly 444,000 cars in the last three months, a figure that is up sharply from the previous quarter, although it's still down nearly 5% from a year ago. as a result of these

better than expected performance, tesla retains the title as the world's top seller of electric cars. meanwhile, there was also good news out of general motors. the detroit auto—maker said electric car sales hit a new record, but those double digit gains still account for only a small percentage of its overall business. nonetheless, the upbeat news is being seen as a positive sign at a time when us car—makers face increased competition from the likes of chinese firm byd, as well as lukewarm consumer demand for electric vehicles. we're getting reports that skydance has reached a preliminary deal to buy paramount's controlling shareholder national amusements. according to the new york times and wall street journal, skydance will pay $1.75 billion for national amusements, giving skydance full control of paramount. shares of paramountjumped in afterhours trade after the reports, but we have yet to get confirmation from any of the media entities in this potential acquisition.

federal reserve chairmanjerome powell. speaking at a european central bank forum mr powell acknowledged there has been significant progress on inflation. however, he wants to see a more sustained downtrend before lowering the cost of borrowing, which currently sits between 5.25% and 5.5%. he said he wanted to see more sustained downtrend, it currently sits between 5.25 and 5.5%. the clock is ticking for chinese and the european union negotiators who are in talks over the eu's plans to impose tariffs on chinese electric vehicles. the provisional tariffs are expected to kick in, on the 4th ofjuly. last month, the eu announced it would impose duties as much as 38% on evs shipped from china. that's on top of the 10% levy on all cars imported to eu countries. these proposed tariffs vary depending on how much each car—maker cooperated with eu investigators looking into chinese government subsidies for the ev industry. among china's biggest car—makers, the tariffs are highest

for saic, which makes the m64 electric car. geely, which owns a stake in volvo, faces a tariff of 20% while a 17.4% duty will be applied to byd brands. i'm joined by automotive industry expert, tu le from sino auto insights. they explained what is at stake for chinese car—makers if no solution is reached. mainly, they're just trying to find a way for the chinese government to reduce or eliminate the tariffs and with the eu they are just trying to do everything they can to stand firm. there is internal pressures from the german auto—makers to reduce or eliminate the tariffs as well, so last week they actually reduced the tariffs by a little bit, but it's more insult to injury. it seems like the eu is going to do everything they can to stand firm with these severe increases on the tariffs.- increases on the tariffs. china sa s it increases on the tariffs. china says it once — increases on the tariffs. china says it once a _ increases on the tariffs. china says it once a mutually - says it once a mutually acceptable solution but what can that realistically look like? i

can that realistically look like? ~' can that realistically look like? ~ ., �* , can that realistically look like? ~ ., �*, ., like? i think what's important is, ou like? i think what's important is. you know. _ like? i think what's important is, you know, before - like? i think what's important is, you know, before my. like? i think what's importantj is, you know, before july four is, you know, beforejuly four if there is any movement, it might be minimum on either sides, both sides specifically looking at the saic close to 50% on the tariffs. they need to be able to sell something to the domestic audience that they are being strong and/ or they are being strong and/ or they are being strong and/ or they are being facing some sort of reduction to save face on both sides. at the eu seems very serious, i would also look at these tariffs as the eu really acknowledging that the chinese tvs that are being built and currently are about 25% of all euv's currently are about 25% of all euv�*s imported into the eu are made in china. its acknowledgement of these products are really good and the domestic competition probably isn't up to the task competing with them. generative ai is getting smarter, on some

university exams. a recent study by the university of reading has found that on tests for psychology courses, answers generated by ai scored higher than those done by undergraduate students. the study also found that 94% of the ai answers were undetected by those marking the exams. to understand the implications this has for the education professor peter scarfe. laid out the implications of this. ai is really not going to be going anywhere, our study has showed is an issue for academic integrity. i think going forward will be looking at a new kind of assessments where we have a set of assessments which are completed in a supervised fashion, so we now know that al can be used and on a set of assessments where we are using and embracing ai and an assessment itself. it are using and embracing ai and an assessment itself.— an assessment itself. it seems almost like _ an assessment itself. it seems almost like counterintuitive - an assessment itself. it seems almost like counterintuitive to | almost like counterintuitive to be tested on how well you can

bad. we can kind of off—load some of the kinds of legwork which allows us to open up our time to think a bit more detail about things. with the olympic games in paris just weeks away, new technology is increasingly important both in sporting arenas and for the audiences watching coverage of the events. lara lewington from the bbcs click programme caught up with olympic gymnastics champion max whitlock to look at technology aiming to enhance viewing experiences at the games. max whitlock is britain's greatest gymnast. he's won multiple titles including three world championship golds and six 0lympic medals, three of those were also gold. but this will be his last time competing at the games. he is retiring after paris, so fans may want to watch his every move. the

olympics of course it provides 0lympics of course it provides great excitement all over the world but despite the fact that athletes move fast, they can't be everywhere all at once. so maybe this is the solution. 29 cameras makeup this volumetric studio which will have more than one use for athletes. all than one use for athletes. all those than one use for athletes. fill those cameras are then fed into a captured pc that runs on intel processing power. we can capture human performances, interactions, singing, dancing, whatever, and full 40. —— full for the. whatever, and full 40. -- full for the. , , ., for the. the end result is a diuital for the. the end result is a digital version _ for the. the end result is a digital version of _ for the. the end result is a digital version of the - for the. the end result is a l digital version of the person which can be beamed into tv studios around the world during broadcast interviews. i am studios around the world during broadcast interviews.— broadcast interviews. i am a team gb — broadcast interviews. i am a team gb gymnast _ broadcast interviews. i am a team gb gymnast and - broadcast interviews. i am a team gb gymnast and i'm l broadcast interviews. i am a - team gb gymnast and i'm going to do— team gb gymnast and i'm going to doa— team gb gymnast and i'm going to do a full somersault in

immediately. and so in the reconstruction process in 3d we had to get it perfect. greece has become the first european nation to introduce a six—day work week across some industries. the new law came into effect on monday, and hopes to boost productivity amongst workers. it is only applicable to certain industries for now. but the change also means that the traditional 40—hour work—week could now be extended to 48 hours, which some labour unions have criticised over concerns of burn—out and fatigue. you can find out all of ours but the stories on her website, just log onto bbc .com/ business, susie mentioned tesla and that is up there as well in the headlines today. i can tell you that the tesla hit significant sales slump earlier this year but is showing significant signs of revival with sales of more than i4% from the prior quarter. that's it from us you're on this edition of business today,

thanks for watching.
