On Sites Like eBay, Strangers No Longer Seen as ‘Just Like You’
COLUMBUS, Ohio – An anonymous stranger you encounter on websites like Yelp or Amazon may seem to be just like you, and a potential friend. But a stranger on a site like eBay is a whole different story.
A new study finds that on websites where people compete against each other, assumptions about strangers change.
Previous research has shown that people have a bias toward thinking that strangers they encounter online are probably just like them. (more…)
Study Points to Need for Interventions That Address Neighborhood Poverty
COLUMBUS, Ohio – Living in a poor neighborhood as an adolescent is linked to an increased risk of getting the sexually transmitted infection (STI) chlamydia in young adulthood, according to new research.
Ohio State University researchers analyzed data from a large national study that tracked youths over time. The analysis suggested that children who lived in poor neighborhoods during their teenage years had an almost 25 percent greater risk of having chlamydia in their early 20s – even if they themselves weren’t poor – than did teenagers living in wealthier settings.

Scientists Design ‘Fishing’ Technique to Show How Foods Improve Health
COLUMBUS, Ohio – New research suggests that a compound abundant in the Mediterranean diet takes away cancer cells’ “superpower” to escape death.
By altering a very specific step in gene regulation, this compound essentially re-educates cancer cells into normal cells that die as scheduled.
One way that cancer cells thrive is by inhibiting a process that would cause them to die on a regular cycle that is subject to strict programming. This study in cells, led by researchers at The Ohio State University’s Comprehensive Cancer Center, found that a compound in certain plant-based foods, called apigenin, could stop breast cancer cells from inhibiting their own death.

COLUMBUS, Ohio – Scientists have delved deeper into the evolutionary history of the fruit fly than ever before to reveal the genetic activity that led to the development of wings – a key to the insect’s ability to survive.
The wings themselves are common research models for this and other species’ appendages. But until now, scientists did not know how the fruit fly, Drosophila melanogaster, first sprouted tiny buds that became flat wings. (more…)
Genomic techniques facilitate discovery that gene expression causes disparity
Although they live in similarly extreme ecosystems at opposite ends of the world, Antarctic insects appear to employ entirely different methods at the genetic level to cope with extremely dry conditions than their counterparts that live north of the Arctic Circle, according to National Science Foundation- (NSF) funded researchers.
Writing in the Proceedings of the National Academy of Sciences, the researchers concluded, “Polar arthropods have developed distinct… mechanisms to cope with similar desiccating conditions.” (more…)
BOSTON — An Ohio State University statistician says that the natural human difficulty with grasping probabilities is preventing Americans from dealing with climate change.
COLUMBUS, Ohio — Though scientists have long believed that complex organic molecules couldn’t survive fossilization, some 350-million-year-old remains of aquatic sea creatures uncovered in Ohio, Indiana, and Iowa have challenged that assumption.
The spindly animals with feathery arms—called crinoids, but better known today by the plant-like name “sea lily”—appear to have been buried alive in storms during the Carboniferous Period, when North America was covered with vast inland seas. Buried quickly and isolated from the water above by layers of fine-grained sediment, their porous skeletons gradually filled with minerals, but some of the pores containing organic molecules were sealed intact.

COLUMBUS, Ohio – New research suggests that zinc helps control infections by gently tapping the brakes on the immune response in a way that prevents out-of-control inflammation that can be damaging and even deadly.
Scientists determined in human cell culture and animal studies that a protein lures zinc into key cells that are first-responders against infection. The zinc then interacts with a process that is vital to the fight against infection and by doing so helps balance the immune response. (more…)
