TORONTO, ON – A new study published by the Social Science Research journal reveals that second-generation Chinese and South Asian immigrants in the US, Canada, and Australia are more successful than the respective mainstream populations (third- and higher-generation whites).

Jeffrey G. Reitz and Naoko Hawkins from the University of Toronto and Heather Zhang from McGill University examined survey and census data from these countries to compare the achievements of immigrants and their offspring. (more…)

COLUMBUS, Ohio – Taking enough omega-3 fatty acid supplements to change the balance of oils in the diet could slow a key biological process linked to aging, new research suggests.

The study showed that most overweight but healthy middle-aged and older adults who took omega-3 supplements for four months altered a ratio of their fatty acid consumption in a way that helped preserve tiny segments of DNA in their white blood cells. (more…)

A professor uses clickers and UD Capture to make a large class feel smaller

Susan McGeary, associate professor in the Department of Geological Sciences at the University of Delaware, incorporated clickers and UD Capture for the first time in spring 2012 to see if she could increase student participation. What McGeary did not expect was the level of engagement in her Geological Hazards course, which is a 250-300 person class.

“Clickers seemed to remove the barrier between me and the students; they approached me more, asked more questions, were more involved during the class — it was exciting,” McGeary said. (more…)

For Some Women, Genes May Influence Pressure to Be Thin

EAST LANSING, Mich. — Genetics may make some women more vulnerable to the pressure of being thin, a study led by Michigan State University researchers has found.

From size-zero models to airbrushed film stars, thinness is portrayed as equaling beauty across Western culture, and it’s an ideal often cited as a cause of eating disorder symptoms in young women. The researchers focused on the potential psychological impact of women buying into this perceived ideal of thinness, which they call thin-ideal internalization. Changes in self-perception and behavior, caused by this idealization, can lead to body dissatisfaction, a preoccupation with weight and other symptoms of eating disorders. (more…)

Obama, Romney supporters: R-E-S-P-E-C-T (just a little bit)

ANN ARBOR— It’s a common refrain during the political season—Republicans and Democrats talk past one another. They claim they live in different universes or come from different species, with little hope for extending empathy across the political aisle.

But University of Michigan researcher Yesim Orhun and her colleague Oleg Urminsky of the University of Chicago say that there exists a greater respect for one another’s views than is generally assumed. (more…)

A new species of plant-eating dinosaur with tiny, 1-inch-long jaws has come to light in South African rocks dating to the early dinosaur era, some 200 million years ago.

This “punk-sized” herbivore is one of a menagerie of bizarre, tiny, fanged plant-eaters called heterodontosaurs, or “different toothed reptiles,” which were among the first dinosaurs to spread across the planet. (more…)

Sticky Paper Offers Cheap, Easy Solution for Paper-Based Diagnostics

A current focus in global health research is to make medical tests that are not just cheap, but virtually free. One such strategy is to start with paper – one of humanity’s oldest technologies – and build a device like a home-based pregnancy test that might work for malaria, diabetes or other diseases.

A University of Washington bioengineer recently developed a way to make regular paper stick to medically interesting molecules. The work produced a chemical trick to make paper-based diagnostics using plain paper, the kind found at office supply stores around the world. (more…)
