The Naked Scientists at the Cambridge Science Festival, with interview guest Dr. Cynan Ellis-Evans, discuss subglacial lakes like Lake Vostok, what Lake Vostok might tell us about life on other planets, whether there is life in lake Vostok, plus how long will the sun last, and what would happen if a bird drank fizzy water ?
World record for the deepest dive with on a single breath is 50 metres
It's False much more at 162 metres, set last year by Loic Leferme. Possible because of an ancient response programmed into all of us called the mammalian diving reflex - when the face hits the water the heart slows by 50% and the circulation shifts, shutting down less essential organs in favour of maintaining blood flow to the heart and brain.
The world's longest hiccupping attack lasted 69 years
It's True American Charles Osbourne died in 1991 having hiccuped continuously since 1922. Long term hiccup attacks can also run in families and are more common in men than women. The only cure with any scientific basis is breathing into a paper bag to raise blood carbon dioxide levels.
A pond containing goldfish becomes alcoholic after a long winter
It's True when the pond freezes over the fish survive the low-oxygen conditions by reducing their metabolism by over 90%, swimming very slowly, and burning up the sugar glucose. Without oxygen they turn the products of their metabolism into alcohol which is peed out into the pond water.
The moon is a quarter of the size of the Earth
It's True but only in terms of its 'diameter'. Obviously the volume of the moon is significantly smaller than the volume of the Earth. The moon has a diameter of 2156 miles and is 239,000 miles (384,000 km) from the Earth. This is still tiny compared with the sun (which is 92 million miles away) and has a diameter 110 times that of the earth and could comfortably accommodate a million planet Earths inside.
The world population is growing
It's True Experts are predicting that the world population will reach 8.9 billion by the year 2050. They had suggested that the population would rise to 9.3 billion from its current total of 6.3 billion, but they have revised their estimate because of a reduction in the present birth rate, and the impact of AIDS.
