Jan. 21, 2013 In a joint research study conducted by the Department of Information Systems of the TU Darmstadt (Prof. Dr. Peter Buxmann) and the Institute of Information Systems of the Humboldt-Universität zu Berlin (Dr. Hanna Krasnova), Facebook members were surveyed regarding their feelings after using the platform. More than one-third of respondents reported predominantly negative feelings, such as frustration. The researchers identified that envying their "Facebook friends" is the major reason for this result.

Jan. 21, 2013 A team of researchers from the Universitat Politècnica de València and specialists from the Hospital Universitari i Politècnic La Fe have developed a new tool, a mathematical model to be exact, to help in the selection of embryos for transfer in fertility treatments.
The model is especially useful for transfers of intermediate quality embryos on the second...

From bullying to relationships: Mapping our online communications

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...

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...

Inaccurate diagnoses of melanoma by smartphone apps could delay doctor visits, life-saving treatment

Jan. 16, 2013 Smartphone applications that claim to evaluate a user's photographs of skin lesions for the likelihood of cancer instead returned highly variable and often inaccurate feedback, according to a study led by researchers at the University of Pittsburgh School of Medicine. The findings, published in JAMA Dermatology and available online January 17, suggest that relying on these "apps" instead of consulting with a physician may delay the diagnosis of melanoma and timely...

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...
