ROY, Gene, Representative discussed on The Naked Scientists


And it turns out that there are constraints to the extent that we think that we can predict this. And there is a new generation of flu vaccines that that are being produced were the strain that's in the vex. Gene is not the best Representative of the strain that circulating in February, but is actually an educated guess of what's going to circulate the following year. These vaccines that will enter clinical trials in about two years from now. It's a bit like when you're driving down the motorway, you should always look at the car not directly in front, but the one in front of the car in front because you see the brake lights go on on that one before the car in front of us going to break. And so it gives you advance warning. You're sort of saying, what if I look at what the viruses doing now, and then I second guess ROY is going to be later. I'll get a much more accurate picture. This is exactly what's happening and and for me, it's really beautiful integration of of basic science, evolutionary biology and fantastic's Valence because the other thing that we have when we drive down the motorway is we have the experience of doing this before and because there is this great surveillance over so many years. One can go back and do retrospective studies. To imagine that it is nineteen eighty nine and then see if we can predict what happens in nineteen ninety in one thousand nine hundred one ninety two and know whether or not the methods of working on and erica's promised me. He's coming back in two years time when the clinical trial launches and tell us how he's getting on that was professor Jerry Smith. Thank you to my other guesses week. We had Sean Lang, Wendy Barclay and Otmar ankle hot and now to finish. It's time for question of the week and not a Murphy has been stuck on this question from Tom. Why is blue sticky blue tack is everywhere probably in every home and every office holding up our posters on our notices, but figuring out what's in this puts us in something of a sticky situation to learn more. I spoke to Jennifer Gakuen a researcher in Dublin, City University. We don't know exactly what blue tech is made of because it's a trade secret, but we do know that contain something called hydrocarbon. Palmer's hydrocarbon polymers are included in most clues at our what turns blue. Back into an adhesive polymers, which are molecules. The form these long chains do tend to be quite sticky because from a chemical point of view, they have a lot of hydrogen on their surface which likes to form very strong physical bums with anything that they touch. So that's part of it, but it's not the whole sticky story. It's actually the squishy nature of the blue tack. That's the real trick, though. Blue tech is put like substance that's movable and able to four blue tech seeps into any little indents on the surface that it's sticking to. This makes it even stickier, but might be whether still blue talk on.
