There is data available at http://www.who.int/mental_health/prevention/suicide/country_reports/en/index.html which contains PDFs split by country.

Here is some badly formatted data form the Japan PDF (at http://www.who.int/entity/mental_health/media/japa.pdf )

Number of suicides by age group and gender. JAPAN, 2004. Age 5-14 15-24 25-34 35-44 45-54 55-64 65-74 75+ All Males 27 1233 2677 3248 4807 5232 2659 1876 21955 Females 22 579 1088 935 1108 1592 1348 1595 8292 Total 49 1812 3765 4183 5915 6824 4007 3471 30247

The age distribution is interesting with the rate increasing and then falling after reaching the age of 65+. I'm not qualified to make any assumptions based on the data, so I'm leaving that somebody else.

Buckyballs Can Store Concentrated Hydrogen 193

Pickens brings news that researchers from Rice University have discovered that it's possible to store hydrogen inside buckyballs. Hydrogen can be an excellent power source, but it is notoriously difficult to store. The buckyballs can contain up to 8% of their weight in hydrogen, and they are strong enough to hold it at a density that rivals the center of Jupiter. "Using a computer model, Yakobson's research team has tracked the strength of each atomic bond in a buckyball and simulated what happened to the bonds as more hydrogen atoms were packed inside. Yakobson said the model promises to be particularly useful because it is scalable, that is it can calculate exactly how much hydrogen a buckyball of any given size can hold, and it can also tell scientists how overstuffed buckyballs burst open and release their cargo."
