Microscopic world of bacteria, fungi and viruses
|
This week on the Naked Scientists we have a whole host of experts in bacteria, fungi and viruses. We'll have Dr Tim Wreghitt (Addenbrooke's Hospital) discussing noroviruses, Dr Ali Ashby discussing her fun work with fungi and in kitchen science with the help of Dr Gillian Fraser we'll be discovering where there are more bacteria: on a toilet seat or a kitchen worktop?

Scott Manalis tells us about the technique he has developed for weighing tiny objects underwater, such as single cells, and even down to a femtogram (thats 0.000000000000001 grams!)
This week, Bob and Chelsea look at how we react to bacteria. Bob looks into how bacteria could protect us from Asthma, while Chelsea explores our skin's reaction to bacterial invasion.
Do suncreams reduce the energy of each photon, thereby taking them below the threshold that could damage your DNA, or do they merely reduce the number that are transmitted through the cream?
Dr Tim Wreghitt explains how noroviruses spread themselves through projectile vomit and use cruise ships as the perfect culture vessel.
I used to be a pig man, and many years ago we had a really bad bout of E. coli, we were losing something like 15-20% of piglets born. A herbalist claimed credit for clearing it up. He put bramble tips and coal dust into the adult pigs’ feed. Was it purely coincidence, or was t...
For kitchen science we tried to see if there's any truth to the urban legend that there's more bacteria on a kitchen worksurface than on a toilet seat.
Dr Ali Ashby on all that is fantastic about fungi. From the worlds largest organism to the flavour of chocolate, we've got lots to thank fungi for!
Norovirus have been compared to influenza viruses, so do noroviruses show the same seasonality as flu?
