Ep 836Cats, catnip, and curious chemicals
You've probably heard of catnip, which makes cats go crazy. There's also another plant called silver vine, which has a similar effect. Now scientists have been nailing down what in silver vine makes cats so excited, but also a surprising bonus effect of the chemical - it makes an effective mosquito repellent! Eva Higginbotham heard how from lead author on the study Masau Miyazaki from Iwate University, which has just been published in the journal Science Advances...Ref: https://advances.sciencemag.org/content/7/4/eabd9135 Like this podcast?

Ep 831Universal Flu Vaccine
The WHO estimates that up to 650,000 people globally die each year from the flu, and one of the tools in our arsenal against it is the seasonal flu vaccine. Recently there's been a huge breakthrough in the search for a universal flu vaccine, that is one vaccine that would give broad protection from lots of different strains of flu. Just published in the journal Nature Medicine, Eva Higginbotham spoke to one of the scientists behind the work: Lynda Coughlan... Like this podcast? Please help us by supporting the Naked Scientists

Ep 830Inhaled vaccines cross from lungs to blood
Traditionally, when someone says "vaccine", the image of a syringe and needle usually springs to mind. But injections need trained staff to administer them, and they're unpleasant, even for people who are not scared of needles. So vaccines you can inhale sound altogether more attractive. And that's what researchers at Rutgers University in the US have been working on. They've found a particular clutch of chemical compounds that are very good at passing harmlessly through the lungs and entering the bloodstream where they can interact with the immune system. What's exciting is that these... Like this podcast? Please help us by supporting the Naked Scientists

Ep 827Alzheimer's: early detection via AI
Recently news was published of an artificial intelligence system which has analysed bits of speech from participants of a long-running study on dementia. These participants were cognitively normal, didn't have signs of dementia, at the time. The system managed to predict the onset of dementia up to 7 years earlier than human doctors. Katie Haylor asked Susan Kohlhass, director of research at Alzheimer's Research UK what she made of the announcement... Like this podcast? Please help us by supporting the Naked Scientists

Ep 826Octopuses taste with their tentacles
Let's dive into the depths and consider the octopus. As well as being famous for its 8 arms, and 3 hearts, octopus vision is also impressive: it helps them spy out dinner, among other things. But light isn't always in great supply when you're hunting around on the seabed, so these creatures have a fascinating ability to taste their surroundings and therefore make decisions about what to eat or not, simply by touching things. Now, a paper from scientists at Harvard explains how this touch-taste system actually works on a molecular level. By studying the cells in the suction cups of the... Like this podcast?

Ep 819MS vaccine using your own brain cells
Could an injection of your own brain cells be a way to halt multiple sclerosis - MS? That's what researchers in the US are finding in mice with the disease. In MS, the immune system attacks the brain and spinal cord, damaging a material called myelin. An extract of this myelin material, injected into the bloodstream, can permanently deactivate the immune cells that cause MS... Like this podcast? Please help us by supporting the Naked Scientists

Ep 815HFpEF: heart failure type is underserved
Have you ever heard of the condition known as "heart failure with preserved ejection fraction"? If not, then you're not alone; despite it representing hundreds of thousands of heart failure cases every year in the UK alone, a new study shows that many doctors don't really understand it, and many patients don't even know they have it. In order to better understand the condition they call "heff peff", Emma Sowden from the University of Manchester and her colleagues have been speaking to people living with it - like Mancunian Mike Wardle - as well as to Phil Sansom...
