year's nobel prize for medicine. first i want to bring you the story. in the first major sign of how the us presidentjoe biden will tackle trade tensions with china is trade representative has outlined us strategy for working with beijing. the us and china all the worlds two biggest economies and for years now there have been tariffs on more than half of what they sell to each other. in a speech she said she would employ all tools to try to change the dynamic between the us and china on trade. she said she would allow some us companies to apply for in exemption from punitive us tariffs but she refused to rule out further tariffs being imposed if there were further disagreements in there were further disagreements in the future. l115 there were further disagreements in the future. ,,

workers, grow our economy and createjobs at american workers, grow our economy and create jobs at home. american workers, grow our economy and createjobs at home. he believes we need to manage the

have it on the programme. this decision to allow some us manufacturers to apply for an exemption to tariffs, surely that's a good sign, isn't it?— a good sign, isn't it? certainly in the short term _

other than we will start talking with the chinese. i think in the short term this suggestibility but the framing of the speech and where policy is likely headed is probably in a more hawkish

today emphasised on renewing america's infrastructure, promoting r&d on manufacturing, our own competitiveness, something we didn't see in the trump administration and working with allies on both individually, in groups like the quad and with the eu and in the wto. again, she sees most of those things as important in changing the playing feel and that we are negotiating with the chinese. in fact it's clear the administration has made more progress on those two parts then in figuring out exactly what it can negotiate with the chinese about. given that background, where do you see trade relations, to be honest, all relations with the us and china going from here? i all relations with the us and china going from here?— all relations with the us and china going from here? i think what

she wants to have several months' time to talk to the chinese about where we are with regard to the phase i agreement both for purchases and china's commitments to make regulatory changes. as well as talk about chinese industrial policies, subsidies and probably sometime in early 2020 to come up with some verdict. it could mean that that verdict. it could mean that that verdict is likely to be negative in which case we will see the us administration start to move more clearly down a line of investigation and potential penalties. scott kennedy. _ and potential penalties. scott kennedy, thank

republicans while blocking his plans to try to raise the us governments step feeling of acting recklessly and dangerously. america's borrowing has reached 28 point or trillion dollars in unless congress agrees to an increase within about a fortnight many parts of the government will have to shut down. mister biden said the effects will be far—reaching. the days ahead even before the defaulting, people may see the value of their retirement accounts strength. will see interest rates go up. which will ultimately raise their mortgage payments and car payments. your savings in your

people want social distancing but because the winning research was all about how we humid sense things without the joints winners american scientists used chilly to identify the senses that enabled the body to feel temperatures and pressure. and that's important because it could lead to new ways of treating pain. the challenge that we set out to solve in the lab was to understand the molecules and signalling pathways that underlie our sense of touch. professorjulius and his team set out to better understand how we experience the world, how touch helps us experience everything from our morning coffee to a hug from a loved one. you might think it is pretty obvious when a cup of coffee is too hot or a drink is too cold, but scientists haven't actually understood fully how we experience those sensations, and that is why this research is deemed to be so important. not only does it improve our understanding, but it could have huge implications for how we manage pain. the research initially came from investigating the burning sensation we feel from eating a hot chilli pepper. they discovered the specific type of receptor that responded to it. from there, the team found other receptors that respond to things like pressure. touch is one of the five senses. but it does something very special, because most cells in our bodies communicate through chemicals. and yet, these touch neurons have to sense physical stimuli, such as pressure and temperature, and in a way transform this information into chemical signals that cells can understand, and no one really knew how this happened. places like san francisco are in the grip of an opioid crisis. more people died here in the city of drugs, mainly from fentanyl overdoses, than from covid last year. the hope is that this research will allow scientists to create more targeted and perhaps even less addictive pain relief in the future. james clayton, bbc news, san francisco. just time to tell you that william
