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 dont know, viewers may b...

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, lets look at the chemistry prize with its scientific breakthroughs that have myriad uses that will benefit humankind. lets have a short video looking at what the prize for chemistry was made for. ...

the nano world is really, really bizarre. when matter is reduced to its smallest dimensions, its 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 use...

then this photo of star swimmer riley gaines and leah thomas after they raced each other spurred this issue. gaines was shouted down when she spoke out to support herself and other women athletes. so today the majority gop in the house of representatives passed a bill to protect female athletes while democrats called this bill and them for doing so trans bullies. >> this bull fuels a virulent hate campaign against kids. >> you want to be a transgender, thats your right. but what about ...

are warning this winter could be extra hard. not just for covid, but for flu, and now a childhood respiratory virus thats going around. it is an important message and were going to go to the white house when he begins speaking. speaking of the president and midterms, biden is going to syracuse this week. yes, syracuse, yes, new york. yes, new york, in the last two weeks before the midterms. hes coming here because as blue as new york is, some of the congressional races are looking a li...

space center where the uncrewed artemis i mission is scheduled to lift off between 8:33 and 10:33 a.m. heres the thing, there are technical issues right now. a hydrogen leak and potentially an engine problem threatening this mornings launch. >> the plan is for artemis one to eventually fly around the moon with three mannequins, including one named commander moonequin. nearly 50 years ago apollo went to the moon. the artemis plans to land humans on the lunar south pole of the moon in th...

links between extremist groups like the oathkeepers and the proud boys and members of former president trumps inner circle. marshall cohen is live in washington this morning with a preview for us. how does the committee plan to connect those dots, marshall? >> reporter: good morning, it is all about the right wing extremist groups and donald trump and the committee has been making the case that this was so much more than a wing k and a n, this was a real affiliation to create a violent...

study. >> did it work? what did they find? >> well, again, i want to say again, it is early, these are small studies, i think in some ways this was proof of concept, but look at some of the findings here. gamma waves, the shorter, high energy waves that were stimulating the front part of the brain, they found that that actually did improve overall longer term sort of memory. they were giving people lists of words, people were able to remember the earliest words better when they stimula...

lady also laid flowers at a memorial site before meeting with the families of the ten victims all killed while shopping and working at a grocery store simply because they were black. this hatred is what led president biden to run for president. and its detailed in the suspects plans. weve learned he made multiple trips to that store as early as march. even speaking with a security guard who the shooter would later kill in this attack we are live from buffalo. joe, first to you. tell us...
