It is a social bookmarking site and users can save links to interesting articles for later use or reference. Its technology is very interesting as it is using a toolbar to take its users to other interesting sites. It has changed its icon but it is still StumbleUpon. Read More …
Researchers have found the emerging “tribes” – communities – on the social networking sites such as Twitter. These communities have common characters, occupation or interest and have their own particular languages.
They worked with functional magnetic resonance images (fMRI) on cortico-striatal connection in the brain of 12 participants, who were diagnosed with internet addiction, and 11 healthy participants. Cortico-striatal circuitry in the brain is associated with the usual addiction related disorders.
Researchers found decreased functional connectivity between frontal and parietal regions of the brain. They found about 24% of reduced connections between the subcortical regions and frontal regions while nearly 27% of reduced connections between the subcortical regions and parietal cortices as compared to the healthy participants. Based on these findings, researchers are of the opinion that decreased functional connectivity between the frontal and parietal regions of the brain could also be found in the different types of addiction.
“Internet addiction is associated with a widespread and significant decrease of functional connectivity in cortico-striatal circuits, in the absence of global changes in brain functional network topology.” Researchers noted.
Researchers wrote that dopamine could be an important chemical in the brain about the functional connectivity differences.
Researchers in this study worked on male participants. However, further research can be done on the differences of the addiction-related consequences on the brain of different genders.
“We may test a hypothesis that structural differences in the brain of men and women would affect the function (e.g., addiction-related symptoms or behaviors) in different manners when they get addicted.” Prof. Soon-Beom Hong, first author of the paper, told SayPeople.com in an email interview.
“Another possibility is that, when men and women get addicted, they may show different clinical features.
“For example, when they get addicted to the “internet”, men may favor online gaming and women may favor social networking.
“If this is plausible, then we may expect different fMRI findings. But we’ll need to question whether the difference is due to gender or other factors.” Soon-Beom Hong added. Read More …
Yahoo Inc. is planning to shut down seven of its products including BlackBerry app. According to the company, the shutdown is among the regular efforts to evaluate and review the series of products.
“The most critical question we ask is whether the experience is truly a daily habit that still resonates for all of you today,” wrote Jay Rossiter, Yahoo’s executive vice president of Platforms.
This is the second group shutdown by the company.
At an investor conference last month, Chief Executive Marissa Mayer signaled about the removal of unwanted apps noting that 60 to 75 mobile apps would be reduced to 12 to 15 important apps. Read More …
Coursera has added 29 new Universities, now it has 62 universities’ affiliations. 16 of the 29 universities are from outside of US, i.e. from 13 countries around the world in 4 different continents, and the courses from those universities will be available in French, Spanish, Chinese and Italian. Chinese, Italian, and Spanish are new to the company.
Now Coursera has 92 new courses and nearly 2.7 million users.
Yahoo has launched the new version of its homepage that is “designed to be more intuitive and personal”, according to Yahoo.
Yahoo has introduced the “newsfeed with infinite scroll” giving the users a huge number of options to read the news articles. Users can login and read the articles by logging in with the Yahoo and Facebook account. This new version of newsfeed will allow the users to specify the topics of interest and will show the news shared by the friends on the social network. Moreover, users can share the contents on Twitter or Facebook.
Yahoo has also added local weather forecasts, Photos from Flickr, Birthdays of Facebook friends. Read More …
Microsoft has recently announced that Outlook.com, webmail service from Microsoft, has gone beyond the mark of 60 million users in just six months. Moreover, the company has also removed the “preview” tag from the service and beginning to switch the Hotmail users to the updated Outlook.com, a process that would be completed by the summer this year. The company planned last year to end the Hotmail service. The users after moving to the new service will retain their hotmail.com email address.
Google image search is among the most used products of the Google. It is good but sometimes even Google’s algorithm is not completely working according to the expectations.
Back in October, an image search for Google became hype, when the phrase “completely wrong” gave the photos of Mitt Romney, Republican Party’s nominee for President of the United States in the 2012 election. Still it is showing (many photos of) Mitt Romney as the hype linked the word with the name.
Researchers have estimated that the Microsoft Kinect game controller could save $30 billion of U.S. healthcare annually by increasing the remote interaction of the physicians and other healthcare staff with the patients.
This report has been published in the International Journal of Electronic Finance.
In the study, researchers noted that the patients’ transport costs living at considerable distances from suitable hospitals and health centers could be reduced by using their proposed Kinect system. Moreover, the chances of hospital-acquired infections could also be reduced. Read More …
