Do video games cause violence? Feds want more research

Scientists and psychologists for years have debated whether there's a connection between video games and real-world violence. Do video games refine hand-eye coordination and spur creativity -- or instead turn you into a sociopath? That question has been raised to a fever pitch following national tragedies such as the one in Newtown, Conn.

And though studies, with the exception of a few, have pointed out that a connection between fantasy video game violence and real-world violence doesn't, in fact, exist, the Centers for Disease Control is stepping up its efforts to research a possible link between the two. … Read more

Parents lack bandwidth to monitor kids' online activity, says study

When the world's most famous companies are run by boys who seem to have only slight familiarity with shaving, it's easy for grown-ups to give up.

Somehow, this newfangled digital world has created an entirely new species of human -- one that ultimately wants to eradicate all species that are currently thought of as human.

Who can even lift an eyebrow, therefore, at new research that suggests parents are largely clueless about their kids' activities on laptops, phones, Facebook, and all the other places to which kids choose to disappear?

A new study from McAfee, touchingly called Digital Deceptions, … Read more

The low, low lowdown on the Hsu Research VTF-3 MK4 subwoofer

Just as with speakers, size matters with subwoofers. Pint-size subs can make bass, and the best mini subs can deliver fairly deep bass, but the volume capability, bass quality, and definition of baby subs can never match what you can get out of something like the $449 Hsu Research VTF-1 MK2 sub I reviewed on this blog last year. That bruiser measures 18x14x17 inches, and has a down-firing 10-inch woofer and a 200-watt amplifier. It's the best under-$500 home theater and music sub I've heard, but I was curious about Hsu's $699 VTF-3 MK4 monster, to … Read more

Coming to a printer near you: Electronics manufacturing

PALO ALTO, Calif. -- Got a large roll-to-roll printer that you're not sure what to do with? You might have a future in electronics manufacturing.

It's still very early days, but researchers at the Palo Alto Research Center (PARC) have been taking significant strides in developing a new technology that makes it possible to print electronic components like sensors, transistors, light-emitters, smart tags, flexible batteries, memory, smart labels, and more.

PARC's work can also bring a new element to 3D printing: adding electronic, sensing or optical functionalities to parts. Printing electronics shares one major trait with that … Read more

Facebookers, beware: That silly update can cost you a job

Little did Ashley Payne know that the festive photo of her holding both a pint of beer and a glass of red wine would lead to her losing her high school teaching job.

The 24-year-old educator posted the image to her Facebook profile, and after a parent complained, school officials told Payne she'd have to choose between resigning and suspension, according to IOL News. She resigned.

If those same school officials were hiring and found a candidate with a similar photo shared on the social Web, it's most likely that person wouldn't even get an interview.

A cheaper iPad Mini 'expected,' says Citi

The iPad Mini is already cheap at $329. But Apple is expected to go even lower, according to a report out Tuesday from Citi Research.

Ciit's Glen Yeung said in a note to investors that Apple is shifting toward more inexpensive products.

"Supply chain checks by Citi's Asia-Pac Technology Team suggest a mix shift surprisingly toward Apple's older iPhone4/4S," he wrote.

Then added. "And with our expectation of a low-end iPhone slated for September launch, followed by a sub-$250 iPad Mini, we expect this trend to persist."

Teens: Facebook is just, like, too much drama

When your hormones are harassing you to within an eyebrow-width of your sanity, all you want is a simple life.

You want to be able to curl up with the kind of social network that understands you and doesn't give you headaches.

That kind of social network is, increasingly, not Facebook.

At least this is what teens seem to have told the Pew Research Center during its latest study.

Indeed, the teens surveyed were disturbed by the increased presence of adults and the increased tendency of other teens to angst-ridden self-expression on Mark Zuckerberg's site.

There is, as … Read more

NASA funds attempt at 3D food printer for pizza

"Star Trek" food replicators will always be the holy grail of space-snack technology, but we could be edging a step closer to the dream thanks to the work of mechanical engineer Anjan Contractor with Systems and Materials Research in Austin, Texas.

Systems and Materials Research recently received a $125,000 grant from NASA to make a pizza. OK, it's a little more complicated than that. Contractor already created a proof-of-concept printer that can print chocolate onto a cookie. His next goal is to print out dough and cook it while printing out sauce and toppings.… Read more

Survey: Most teens take steps to protect their privacy (podcast)

A survey conducted by the Pew Research Center's Internet & American Life Project and Harvard's Berkman Center for Internet & Society has mostly good news about how teens approach privacy issues on social-networking services.

While "teens are sharing more information about themselves on social media sites than they did in the past," according to the study, "few teens embrace a fully public approach to social media," but "take an array of steps to restrict and prune their profiles." Here's the full report.

The study also found that:

Teen Twitter use has … Read more
