Lithium in water 'curbs suicide' Drinking water which contains the element lithium may reduce the risk of suicide, a Japanese study suggests.
Researchers examined levels of lithium in drinking water and suicide rates in the prefecture of Oita, which has a population of more than one million. The suicide rate was significantly lower in those areas with the highest levels of the element, they wrote in the British Journal of Psychiatry. High doses of lithium are already used to treat serious mood disorders. But the team from the universities of Oita and Hiroshima found that even relatively low levels appeared to have a positive impact of suicide rates. Levels ranged from 0.7 to 59 micrograms per litre. Bolivia holds key to electric car future. High in the Andes, in a remote corner of Bolivia, lies more than half the world's reserves of a mineral that could radically reduce our reliance on dwindling fossil fuels.
Lithium carries a great promise. It could help power the fuel efficient electric or petrol-electric hybrid vehicles of the future. But, as is the case with fossil fuels, it is a limited resource. Lithium carbonate is already in the batteries of laptop computers and mobile phones. El misterio de la multiplicación del agua en la Luna.
