Redefining what it means to be narcissistic in a social media world

  • PDF
TechAndComputer (July 11, 2012) — A new study conducted by associate professor Bruce McKinney at the University of North Carolina Wilmington shows Facebook users are not as narcissistic as once thought.

While previous studies such as Laura Buffardi and W. Keith Campbell's 2008 paper in Personality and Social Psychology Bulletin showed a correlation between Facebook and narcissism, McKinney's new study, Narcissism or Openness?: College Students' Use of Facebook and Twitter found no relationship between Facebook usage sand narcissistic traits. Lynne Kelly and Robert L. Duran of The University of Hartford coauthored the study, which was recently published in the newest volume of Communication Research Reports.

TechAndComputer (June 13, 2012) — Viewing Facebook and Flickr photos on a smart phone are becoming common practice. But according to a recently published Journal of Vision study, pictures on the small screen often appear distorted. Vision scientists found that perceptual distortions occur because picture takers do not take their viewing distance into account.

The researchers propose the use of longer focal lengths -- 100mm -- to create content that is viewed on the small screens...

Copper-nickel nanowires could be perfect fit for printable electronics

  • PDF
TechAndComputer (May 29, 2012) — While the Statue of Liberty and old pennies may continue to turn green, printed electronics and media screens made of copper nanowires will always keep their original color.

Duke University chemists created a new set of flexible, electrically conductive nanowires from thin strands of copper atoms mixed with nickel. The copper-nickel nanowires, in the form of a film, conduct electricity even under conditions that break down the transfer of...

Tiny robots for less invasive surgery

  • PDF
TechAndComputer (May 25, 2012) — Millions of Europeans undergo abdominal surgery each year to treat a range of different disorders, from cancer and heart disease to obesity. EU-funded researchers are developing innovative micro-robotics and micro-system technologies to make such surgeries less complicated, invasive and costly.

Surgical procedures have improved rapidly in recent years aided by technology that is gradually making the surgeon's scalpel a thing of the past --...

New research could mean faster computers and better smart phones

  • PDF
TechAndComputer (May 15, 2012) — Graphene and carbon nanotubes could improve the electronics used in computers and mobile phones, reveals new research from the University of Gothenburg, Sweden.

Carbon nanotubes and graphene are both made up of carbon and have unique properties. Graphene comprises an atom-thick layer of carbon atoms, while carbon nanotubes can be likened to a graphene sheet that has been rolled up to form a tube.

"If you stretch a graphene sheet from end to...
