The largest study yet into the mental health of social media users has shown there's a correlation between its use and depression.

The University of Pittsburgh School of Medicine research, published in the next issue of the medical journal Depression and Anxiety, found that people who checked social media the most frequently were 2.7 times more likely to suffer from depression than their counterparts. Those who spent the most actual time on such sites were 1.7 times more likely to be depressed.

"Because social media has become such an integrated component of human interaction, it is important for clinicians interacting with young adults to recognize the balance to be struck in encouraging potential positive use, while redirecting from problematic use," said senior author Brian Primack, director of Pitt's Center for Research on Media, Technology and Health.

The researchers interviewed 1,787 US adults between the ages of 19 and 32 and monitored their use of Facebook, YouTube, Twitter, Google Plus, Instagram, Snapchat, Reddit, Tumblr, Pinterest, Vine and LinkedIn. The average user spent 61 minutes per day online and logged on around 30 times a week.

The data was controlled for other contributory factors for depression, including age, sex, race, ethnicity, relationship status, living situation, household income and education level. And the researchers say that while correlation is clear, causation has not been proven.

"Exposure to highly idealized representations of peers on social media elicits feelings of envy and the distorted belief that others lead happier, more successful lives," the study states.

"It may be that people who already are depressed are turning to social media to fill a void," said lead author Lui yi Lin, adding that on the other hand, social media might cause depression, which would then spur the use of more social media in a vicious cycle.

Lin said that a person's presence on social media sites could increase the possibility of cyberbullying, and users could feel that their time spent online is wasted, which could make depression more likely.

"All social media exposures are not the same," said Dr Primack.

"Future studies should examine whether there may be different risks for depression depending on whether the social media interactions people have tend to be more active vs passive or whether they tend to be more confrontational vs supportive. This would help us develop more fine-grained recommendations around social media use." ®

    In-brief Governments around the world should pass intellectual property laws that grant rights to AI systems, two academics at the University of New South Wales in Australia argued.

    Alexandra George, and Toby Walsh, professors of law and AI, respectively, believe failing to recognize machines as inventors could have long-lasting impacts on economies and societies. 

    "If courts and governments decide that AI-made inventions cannot be patented, the implications could be huge," they wrote in a comment article published in Nature. "Funders and businesses would be less incentivized to pursue useful research using AI inventors when a return on their investment could be limited. Society could miss out on the development of worthwhile and life-saving inventions."

    These government files are part of a larger collection of records that discuss the nature, reach, and use of secret Presidential Emergency Action Documents: these are executive orders, announcements, and statements to Congress that are all ready to sign and send out as soon as a doomsday scenario occurs. PEADs are supposed to give America's commander-in-chief immediate extraordinary powers to overcome extraordinary events.

  • Stolen university credentials up for sale by Russian crooks, FBI warns
    Forget dark-web souks, thousands of these are already being traded on public bazaars

    Russian crooks are selling network credentials and virtual private network access for a "multitude" of US universities and colleges on criminal marketplaces, according to the FBI.

    According to a warning issued on Thursday, these stolen credentials sell for thousands of dollars on both dark web and public internet forums, and could lead to subsequent cyberattacks against individual employees or the schools themselves.

    "The exposure of usernames and passwords can lead to brute force credential stuffing computer network attacks, whereby attackers attempt logins across various internet sites or exploit them for subsequent cyber attacks as criminal actors take advantage of users recycling the same credentials across multiple accounts, internet sites, and services," the Feds' alert [PDF] said.
