Michel Guillot (U-Penn) evaluates potential explanations for the migrant mortality advantage found in prior studies, including methodological pitfalls.

Kaare Christensen (Duke) searches for genes/variants associated with healthy aging phenotypes in all surviving participants of the Long Life Family Study.

Jenny Tung (Duke) and colleagues examine the relationship between chronic social stress and gene expression in immune cells among female macaques.

John Trojanowski (U-Penn), director of the Udall Center for Parkinson’s Research, studies the molecular mechanisms of neuron dysfunction and degeneration in PD.

Ronald Lee and Andrew Mason (UC-Berkeley) collect and analyze data on formal and informal support systems for the elderly across the globe via the NTA.

Sanjay Basu (Stanford) develops ‘cohort filtering models’ to link health outcomes and social program participation data at the individual level over decades.

Using vital records, decennial census, Social Security, and Medicare data, William Dow (UC-Berkeley) is constructing state-level estimates of all-cause mortality by age, sex and year, 1933-2007.

Teresa Seeman (UCLA), Chloe Bird (RAND), and colleagues examine WHI data to identify factors contributing to optimal aging among women 80 years and older.

Karen Cruickshanks (Wisconsin) studies the epidemiology of sensory and cognitive changes in Baby Boomers to further the development of interventions to prevent or delay older-age impairments.

Luis Rosero-Bixby and William Dow report a significantly higher age-adjusted mortality rate among the poorest quartile of Americans than their Costa Rican counterparts. They attribute this to more unequal life expectancy outcomes across the economic spectrum in the U.S. than in Costa Rica. Poor Americans under 65 die at a rate 3.4 times higher than their rich counterparts, while that difference is just 1.5 in Costa Rica. The researchers say: “From a life-expectancy standpoint, it is better to live in Costa Rica for low-[income] individuals, whereas it is better to live in the United States for high-[income] people younger than 65.”
