and he goes on to say that. our correspondent, james waterhouse who is in the poltava region in central ukraine explained what this means. it is significant in the sense that ukraine can still navigate russian air defences and strike in the heart of a peninsula that russia has held so tightly onto since 2014. now, the novocherkassk was in port, in feodosiya, suggesting that it was probably being loaded with men, equipment, or both. now, this is a major vessel, it s enormous, and it will no doubt hamper russia s ability to supply troops further north in ukrainian territory it occupies. what is less clear is for how long operations will be disrupted. we ve seen ukraine launch long range missiles over the past year to great effect for kyiv. it has undermined russia s presence there and it has also frustrated supply lines. there is no doubt that russia s navy, the dominance it enjoys in the black sea and off the coast of crimea, that has been weakened slightly with these long
the nano world is really, really bizarre. when matter is reduced to its smallest dimensions, it s made up of quantum dots nanoparticles so tiny that their size determines their properties. alexey ekimov, moungi bawendi and louis brus discovered and developed this artificially created collection of semiconducting nanoparticles. they are just a few millionths of a millimetre wide and glow blue, red or green when exposed to light. quantum dots already have commercial and scientific uses and, in future, could contribute to flexible electronics, thinner solar cells and encrypted quantum communication. so, moungi bawendi, erm, i don t know, viewers may be watching this programme on qled tv one of the things that have arisen from the work that you ve done so just tell us about how your work collectively can be used to improve lives. so, qleds is one of the biggest moneymaking applications of quantum dots, but the field, in the last few decades, has grown enormously and there s
three us military personnel one of them critically. pictures of the attack have been posted on social media the bbc has not yet verified these videos. in a statement us defence secretary lloyd austin said that military forces conducted necessary and proportionate strikes on kataib hezbollah and affiliated groups in iraq. he added, we are committed and fully prepared to take further necessary measures to protect our people and ourfacilities. live now tojerusalem and our correspondent shaimaa khalil. thank you forjoining us on the programme. what more do we know about this us air in northern iraq? we know that this is the latest in what has been an escalation in strikes and targeting of us facilities, both in iraq and in syria. this time, it was the erbil air base which resulted in three injuries of us military personnel, one of them seriously. the statement that you mentioned from lloyd austin, the defence secretary, saying that the us will respond and protect its faci

of sweden and prince daniel, as well as students from here in sweden. welcome to nobel minds and the second of our two programmes. laureates, this is the first time that some of you have been brought together in discussion on television. congratulations to you all. thank you. applause. first, let s look at the chemistry prize with its scientific breakthroughs that have myriad uses that will benefit humankind. let s have a short video looking at what the prize for chemistry was made for. it s very strange. the nano world is really, really bizarre. when matter is reduced to its smallest dimensions, it s made up of quantum dots nanoparticles so tiny that their size determines their properties. alexey ekimov, moungi bawendi and louis brus discovered and developed this artificially created collection of semiconducting nanoparticles. they are just a few millionths of a millimetre wide and glow blue, red or green when exposed to light. quantum dots already have commercial and scie
