A small thing like a bit of fresh air can be good for fishes as well as for humans. But a diet that is too fatty or sugary can be damaging to the brain. Come along to this evening of pints and science, and learn from local scientists about the latest research on an eclectic mix of jumping fish and high-density diets. Join us for a great night of science chat and for a chance to win Pint of Science goodies!
Airtime: who jumps and how high… out of the water?
Fish like being in water, and there seems no reason for them to ever want to leave it. But some species enjoy a little airtime every now and then, momentarily breaching the water after a powerful burst of vertical swimming up to the surface. Some aquatic mammals do the same - dolphins and even some whales are famous for their jumping. Why do some water-borne species breach the surface, which species are the most athletic breachers, and what are the universal factors that limit the height they can obtain? Join us to learn more about jumping fish and cetaceans: discover the latent power of Britain’s biggest fish, the basking shark, and find out about the best pound for pound jumpers in the world – you may well have eaten one for dinner!
Diets and dementia: are we overeating our way to Alzheimer’s?
Leigh Gibson (Reader)
You may not be surprised to learn that eating a diet high in saturated fat for most of one’s life increases one’s risk of dementia in old age – what is bad for the heart is bad for the brain. However, rather more worrying is evidence that relationships between poor diet and poor cognitive abilities, especially memory and learning, can be seen in younger adults and even children, despite appearing otherwise healthy, and certainly not obviously malnourished. I will present and discuss some of these findings, and introduce an emerging idea that energy-dense diets high in fat and sugar may damage the very part of the brain that would normally help us regulate our appetites and resist overeating such foods – a potential diet-obesity-dementia vicious circle.
