across asia mean some workers live from our studio in singapore. this is bbc news. it s newsday. welcome to bbc news broadcasting to viewers in the uk and around the world. we begin in washington where the head of the company behind the artificial intelligence tool chatgpt has told lawmakers that government regulation is crucial to keep the industry safe. we ve seen tech ceos get a congressional grilling before. but that s not what happened here. appearing before a senate panel, sam altman said that al could be as significant as the invention of the printing press, claiming it had the potential to improve nearly every aspect of our lives. but he also admitted the technology also poses serious risks. my worst fears are that we cause significant. we the field, the technology, the industry cause significant harm to the world. i think that could happen in a lot of different ways. it s why we started the company. it s a big part of why i m here today and why we ve been here in
first, i think heat does not get the same kind of attention compared to other climate and weather hazards, because it is largely invisible. and also in this case, we undertake work in singapore and beyond singapore, in southeast asia, looking at workers under extreme conditions, in hope to recommend practical strategies to optimise health and work productivity. and you actually mentioned the physical toll on delivery riders in seoul, the same as on an ultra marathon runner. can you just talk us through? yeah, i think that was quite disturbing on one hand, because coming from a sport science perspective, and one look with internal temperature of 38 ish, heart rate, cardiovascular strain of 130 beats per minute, from an acute exercise perspective, it
and you actually mentioned the physical toll on delivery riders in seoul, the same as on an ultra marathon runner. can you just talk us through? yeah, i think that was quite disturbing on one hand, because coming from a sport perspective, and one look with internal temperature of 38 ish, heart rate, cardiovascular strain of 130 beats per minute, from an acute exercise perspective, it seems to be doable. but bear in mind these workers are doing this job every day, sometimes seven days a week, many weeks, many months, many years. so it s not rocket science for us to realise that at some point, the physiological system will be compromised. and yeah, if you just compare that ultramarathon, it would probably do one or few races a year to have that kind
that s how significant that is. reporter: and nasa came up with this technology to help their astronauts. in space you re weightless. one of the big concerns from an exercise perspective was about weight bearing. if you re at the space station for 90 days and you re not bearing any weight, your bone will demineralize. reporter: just about everyone can use it. recreational runners like jenna. patients recovering from injuries. people with weight issues or osteoporosis. to use it runners or walkersrsut on special shorts. then they step into a chamber. they re zipped in and air is taken ouou like what happens in an airplane. the speed and incline is adjusted. but what does running without weight feel like? if you re at the county fair and you lay out in this thing and the wind blows you up and then brings you up and down that way, that s how i compare it to, only you re standing up but able to bear weight. reporter: if you take weight off the calorie burn won t be the same. bria
