Credit Card Debt: Younger People Borrow More Heavily and Repay More Slowly, Study Finds

COLUMBUS, Ohio – Younger Americans not only take on relatively more credit card debt than their elders, but they are also paying it off at a slower rate, according to a first-of-its-kind study.

The findings suggest that younger generations may continue to add credit card debt into their 70s, and die still owing money on their cards.

“If what we found continues to hold true, we may have more elderly people with substantial financial problems in the future,” said Lucia Dunn, co-author of the study and professor of economics at Ohio State University. (more…)

Yale Team Finds Order Amidst the Chaos Within the Human Genome; Mom and Dad’s Contributions Counted and Fossil DNA Not Dead After All

The Encyclopedia of DNA Elements (ENCODE) project is the effort of hundreds of scientists to describe the workings of the human genome. Their research, outlined in 30 papers published in multiple journals Sept. 5, has confirmed our genome is far more complex than originally thought.  Regions that contain instructions for making proteins, which carry out life’s functions, account for only about 1 percent of our genome. ENCODE has shed light on the other 99%. Almost 80 percent of the genome is biochemically active, much of it involved in some sort of regulation of genes. Vast regions of our DNA once considered “junk” contain some 400,000 regulators called enhancers, which play a key role activating or silencing genes despite residing far away from the gene itself. Yale University researchers played a key role ENCODE, helping to author 9 of the 30 papers published in four journals on Sept. 5. Some of their work is described below.

The massive Encyclopedia of DNA Elements (ENCODE) unveiled Sept. 5 reveals a human genome vastly more rich and complex than envisioned even a decade ago. In a key supporting paper published in the journal Nature, the lab of Yale’s Mark Gerstein, the Albert L. Williams Professor of Biomedical Informatics, has found order amidst the seeming chaos of trillions of potential molecular interactions. (more…)

Model Shows Dramatic Global Decline in Ratio of Workers to Retired People

A new statistical model predicts that by 2100 the number of people older than 85 worldwide will increase more than previously estimated, and there will be fewer working-age adults to support them than previously expected.

The findings, reported by researchers at the University of Washington and the United Nations, suggest an even greater decrease in the coming decades in support for social security programs for elderly adults.

Lead author Adrian Raftery, UW professor of statistics and sociology, was surprised by how dramatically the proportion of the world’s “oldest old” will increase by the end of the century. (more…)

Income Inequality Leads to More U.S. Deaths, Study Finds

COLUMBUS, Ohio – A new study provides the best evidence to date that higher levels of income inequality in the United States actually lead to more deaths in the country over a period of years.

The findings suggest that income inequality at any one point doesn’t work instantaneously – it begins increasing mortality rates 5 years later, and its influence peaks after 7 years, before fading after 12 years.

“This finding is striking and it supports the argument that income inequality is a public health concern,” said Hui Zheng, author of the study and assistant professor of sociology at Ohio State University. (more…)

Scientists Project Changes in Rainfall Patterns for Next 30 Years

Scientists at the University of Hawaiʻi at Mānoa have projected an increased frequency of heavy rainfall events, but a decrease in rainfall intensity during the next 30 years (20112040) for the southern shoreline of Oʻahu, according to a recent study published in the Journal of Geophysical Research.

Chase Norton, a Meteorology Research Assistant at the School of Ocean and Earth Science and Technology (SOEST) at UH Mānoa, and colleagues (Professors Pao-Shin Chu and Thomas Schroeder) used a statistical model; rainfall data from rainfall gauges on Oahu, Hawaiʻi; and a suite of General Circulation Models (GCMs) from the Intergovernmental Panel on Climate Change (IPCC) to project future patterns of heavy rainfall events on Oʻahu. GCMs play a pivotal role in the understanding of climate change and associated local changes in weather. (more…)
