Gen Xers Lead Happy, Balanced Lives - the University of Michigan Institute for Social Research publishes a 'surprisingly positive portrait' of GenX. Here is the full report on the cohort study (PDF).
The Harvard Study of Adult Development is the longest prospective study of mental and physical well-being ever conducted. For 72 years, researchers at Harvard have been following 824 individuals through war, career, marriage and divorce, parenthood and grandparenthood, and old age. Designer Laura Javier took ten of those cases and visualized them in the Elements of Happiness. [via flowingdata]
Epidemiology: Study of a lifetime. "In 1946, scientists started tracking thousands of British children born during one cold March week. On their 65th birthday, the study members find themselves more scientifically valuable than ever before." [more inside]
The winter of 1944–45 is known as the ‘Hunger Winter’ in The Netherlands, which was occupied by the Germans in May 1940. Beginning in September 1944, Allied troops had liberated most of the South of the country, but their advance towards the North came to a stop at the Waal and Rhine rivers and the battle of Arnhem. In support of the Allied war effort, the Dutch government in exile in London called for a national railway strike to hinder German military initiatives. In retaliation, in October 1944, the German authorities blocked all food supplies to the occupied West of the country. Despite the war, nutrition in The Netherlands had generally been adequate up to October 1944. Thereafter, food supplies became increasingly scarce. By November 26, 1944, official rations, which eventually consisted of little more than bread and potatoes, had fallen below 1000 kcal per day, and by April 1945, they were as low as 500 kcal per day. Widespread starvation was seen especially in the cities of the western Netherlands. Food supplies were restored immediately after liberation on May 5, 1945.But for many, who weren't even born when it started, the hongerwinter continues. Why? In part because "certain environmental conditions early in human development can result in persistent changes in epigenetic information" via DNA methylation. Epigenetics seems like a little bit of Lamarckism: environmental effects on a parent -- or even a grandparent -- can be passed to offspring, even without permanent changes to DNA. (previously)
