From bullying to relationships: Mapping our online communications

  • PDF
Jan. 19, 2013 — When we typically think of kids who are the victims of school bullying, what comes to mind are isolated youth who do not fit in. A new study, however, shows that when that harassment occurs online, the victims tend to be in mainstream social groups -- and they are often friends or former friends, not strangers.

The research is part of a burgeoning field of study into the effects of social media on everyday relationships and behavior. Personality and social psychologists are finding surprising ways in which people's online environments and relationships reflect and influence their real-world ones, as presented January 19 at the Society for Personality and Social Psychology (SPSP) annual meeting in New...

Vulnerabilities in security of personal genetic information

  • PDF
Jan. 17, 2013 — Using only a computer, an Internet connection, and publicly accessible online resources, a team of Whitehead Institute researchers has been able to identify nearly 50 individuals who had submitted personal genetic material as participants in genomic studies.

Intent on conducting an exercise in "vulnerability research" -- a common practice in the field of information security -- the team took a multi-step approach to prove that under certain circumstances, the...

Jan. 16, 2013 — For the last ten years, theoretical physicists have shown that the intense connections generated between particles as established in the quantum law of 'entanglement' may hold the key to eventual teleportation of quantum information.

Now, for the first time, researchers have...

Robot allows 'remote presence' in programming brain and spine stimulators

  • PDF
Jan. 16, 2013 — With the rapidly expanding use of brain and spinal cord stimulation therapy (neuromodulation), new "remote presence" technologies may help to meet the demand for experts to perform stimulator programming, reports a study in the January issue of Neurosurgery.

The preliminary study by Dr. Ivar Mendez of Queen Elizabeth II Health Sciences Centre in Halifax, Nova Scotia, Canada, supports the feasibility and safety of using a remote presence robot -- called the "RP-7"...

Fashion blogs: How do ordinary consumers harness social media to become style leaders?

  • PDF
Jan. 15, 2013 — The Internet has given consumers the unprecedented opportunity to reach a mass audience and thereby advance their social position through displays of good taste, according to a new study in the Journal of Consumer Research.

"Ordinary consumers were previously limited to sharing their views and tastes within their circle of friends and acquaintances, and only media professionals and others in powerful positions could reach a mass audience. But the Internet has...
