COLUMBUS, Ohio – Both marriage and divorce can act as “weight shocks,” leading people to add a few extra pounds – especially among those over age 30 – according to a new study.

But when it comes to large weight gains, the effects of marital transitions are quite different for men than they are for women.

For men, the risk of a large weight gain increased most prominently after a divorce. But for women, the risk of a large weight gain was most likely after marriage. (more…)

Conflict Levels Don’t Change Much Over Course of Marriage

COLUMBUS, Ohio – Think about how much you fight and argue with your spouse today. A new study suggests that your current level of conflict probably won’t change much for the remainder of your marriage.

That may be good news for the 16 percent of couples who report little conflict or even the 60 percent who have only moderate levels of conflict. But it’s not such happy news for the 22 percent of couples who say they fight and argue with each other a lot.

The study followed nearly 1,000 couples over 20 years, from 1980 to 2000. (more…)

Jailhouse Phone Calls Reveal Why Domestic Violence Victims Recant

COLUMBUS, Ohio – A new study uses – for the first time – recorded jailhouse telephone conversations between men charged with felony domestic violence and their victims to help reveal why some victims decide not to follow through on the charges.

Researchers listened to telephone conversations between 17 accused male abusers in a Washington state detention facility and their female victims, all of whom decided to withdraw their accusations of abuse. For each of the couples, the researchers analyzed up to about three hours of phone conversations. (more…)

Salmonella Stays Deadly With a ‘Beta Version’ of Cell Behavior

COLUMBUS, Ohio – Salmonella cells have hijacked the protein-building process to maintain their ability to cause illness, new research suggests.

Scientists say that these bacteria have modified what has long been considered typical cell behavior by using a beta form of an amino acid – as opposed to an alpha form – during the act of making proteins. (more…)

Ecologist: Up-and-Coming Forests Will Remain Important Carbon Sinks

COLUMBUS, Ohio – The aging forests of the Upper Great Lakes could be considered the baby boomers of the region’s ecosystem.

The decline of trees in this area is a cause for concern among policymakers and ecologists who wonder whether the end of the forests’ most productive years means they will no longer offer the benefits they are known for: cleansed air, fertile soil, filtered water and, most important to climate change analysts, carbon storage that offsets greenhouse gas emissions.

One Tiny Electron Could be Key to Future Drugs That Repair Sunburn

COLUMBUS, Ohio – Researchers who have been working for nearly a decade to piece together the process by which an enzyme repairs sun-damaged DNA have finally witnessed the entire process in full detail in the laboratory.

What they saw contradicts fundamental notions of how key biological molecules break up during the repair of sunburn – and that knowledge could someday lead to drugs or even lotions that could heal sunburn in humans. (more…)

Omega-3 Reduces Anxiety and Inflammation in Healthy Students

COLUMBUS, Ohio – A new study gauging the impact of consuming more fish oil showed a marked reduction both in inflammation and, surprisingly, in anxiety among a cohort of healthy young people.

The findings suggest that if young participants can get such improvements from specific dietary supplements, then the elderly and people at high risk for certain diseases might benefit even more. (more…)

Public Firms Weathered Recession Better Than Expected

The prevailing narrative of the financial crisis revolves around banks’ reduced ability to issue loans, but a new paper by University of Arizona associate professor of finance Kathy Kahle reveals that the credit supply shock did not affect publicly traded firms as much as expected.

Bank losses from toxic assets were responsible for the credit contraction, but those toxic assets – mostly mortgage-backed securities – are not directly related to the performance of industrial firms. (more…)
