The Right to Vote
A lot is up for grabs this November in America—the presidency of the United States, for one. Not to mention a third of U.S. Senate seats, all seats in the U.S. House, and state-level amendments on issues ranging from voter ID to same-sex marriage (Minnesota has both on the ballot).
But almost six million Americans will sit this one out because of something they’ve done. They’re felons—perpetrators, at some point in their lives, of a serious crime. (more…)
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

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…)
