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…)
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…)
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…)
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…)
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…)
Through a new Multidisciplinary University Research Initiative (MURI) awarded by the Air Force Office of Scientific Research, Brown will lead an effort to study new optical materials and their interactions with light at the quantum scale. The initiative, which includes six other top universities, will receive $4.5 million over three years, with a possible two-year extension.
Harnessing the power of light at the quantum scale could clear the way for superfast optical microprocessors, high-capacity optical memory, securely encrypted communication, and untold other technologies. But before any of these potential applications sees the light of day, substantial obstacles must be overcome — not the least of which is the fact that the wavelength of light is larger than quantum-scale objects, limiting the range of possible light-matter interactions.

One of the things that made digital technology evolving is the fact that the quality of videos and images are continuously improving through the years. With this, you need to have the best space to accommodate such changes. People all over the world can’t get stuck with a small space on their computer and for this reason, external memory for backup was made. Floppy discs are already a thing of the past. Now, flash drives and other compact but efficient devices have replaced these things. (more…)
