The Helix Nebula: Bigger in Death than Life

A dying star is refusing to go quietly into the night, as seen in this combined infrared and ultraviolet view from NASA’s Spitzer Space Telescope and the Galaxy Evolution Explorer (GALEX), which NASA has lent to the California Institute of Technology in Pasadena. In death, the star’s dusty outer layers are unraveling into space, glowing from the intense ultraviolet radiation being pumped out by the hot stellar core.

This object, called the Helix nebula, lies 650 light-years away in the constellation of Aquarius. Also known by the catalog number NGC 7293, it is a typical example of a class of objects called planetary nebulae. Discovered in the 18th century, these cosmic works of art were erroneously named for their resemblance to gas-giant planets. (more…)

UCLA Astronomers Discover Star Racing Around Black Hole at Center of Our Galaxy

Discovery crucial to revealing fabric of space and time around black hole

UCLA astronomers report the discovery of a remarkable star that orbits the enormous black hole at the center of our Milky Way galaxy in a blistering 11-and-a-half years — the shortest known orbit of any star near this black hole. (more…)

Second-generation Immigrants Outperform Mainstream Populations in the US, Canada, and Australia

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…)

Omega-3 Supplements May Slow a Biological Effect of Aging

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. (more…)

Easy Guider: Intuitive Visual Control Provides Faster Remote Operation of Robots

Using a novel method of integrating video technology and familiar control devices, a research team from Georgia Tech and the Georgia Tech Research Institute (GTRI) is developing a technique to simplify remote control of robotic devices. (more…)

Technology in the Classroom

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…)
