We at PopSci love Sonos, the wireless music streaming system that has won two Best of What’s New awards over the years. And since imitation is the sincerest form of flattery, the Linksys division of Cisco seems to love Sonos too. They’ve come out with their own version of the product--with a few features that may be better.

Apparently, Rupert Till, an expert in acoustics and music technology at Huddersfield University in northern England, knows where to find a good party. Till took a second look, or rather, a second hear, at the 5,000-year-old Stonehenge and discovered that its huge stone slabs reflected sound perfectly, making the site the perfect place to listen to repetitive, trance-like music.

With about half of the United States’ workforce classified as “white collar”, a new study out of Canada is relevant food for thought-- but don’t think about it too much! The study, which examined calories consumed after participants completed various intellectually challenging activities, determined that test subjects ate more after finishing more strenuous intellectual activities than when they finished intellectual activities that were less demanding.

Two days before the Consumer Electronics Show officially starts, the first products debuted at CES Unveiled on Tuesday evening. Many of the tables at the Venetian conference center in Vegas looked best-suited to an obscure trade fair, with information about USB and HDMI specifications, for example.

Every issue has two sides and at ProCon.org they offer the pros and cons to each.

At long last -- and after we jealously watched Sharp's debut in Japan last year -- wireless high-def TVs have come to the States. LG's 55-inch LHX LCD television features a separate "media box" that sources like cable boxes and Blu-ray players plug into. (Other products from Sony and Geffen are add-on units.) The box beams digital video and audio to the one-inch-thick TV using 60-gigahertz technology from SiBeam called WirelessHD.

Chances are you've played Rock, Paper, Scissors, but how do you calculate your strategy, if you have one at all?

In Rock, Paper, Scissors: Game Theory in Everyday Life, physicist Len Fisher points out that putting yourself in your opponent's mindset is a key to success in the game.

There's playing online games, and then there's collecting 68 virtual "husbands" in a game. That's when Chinese parents intervene and send their wayward offspring to a boot camp staffed by soldiers of the People's Liberation Army.

Details are still fuzzy, but with very little fanfare it appears the world's first cell phone with a built-in projector has arrived. A company called Logic Wireless is claiming a CES debut of The Logic Bolt (in partnership with T-Mobile, no less). The phone has "razor-sharp" projections which can grow its screen size by 3000 percent and still retains a remarkably slim footprint, if the photos are any indication.

While it’s a safe bet that few Hamas members know the lyrics to “the Star Spangled Banner”, very little separates their activities from those witnessed by Francis Scott Key centuries ago. In what has become a hallmark of guerilla war, Hamas has used a mixture of low-tech weapons and simple tactics to stymie a technologically superior enemy.

I'm a non-geek, a non-Linux user and a non-male. I had never hacked anything in my life. And I had no plans -- or foreseeable need -- to do so.

Then, I discovered PureData. When an audio engineer friend mentioned the open-source programming language that uses rectangular boxes to build audio, video and graphics, I was intrigued.

After weeks of damaging midnight environmental rulings that have removed crucial endangered species protections, restrictions on mining the Grand Canyon, and allowed leasing of public lands for oil development, President Bush protected a whopping 195,000 square miles of the central Pacific’s tropical blue heart. With the stroke of a pen, he created the Mariana, Rose Atoll and Pacific Remote Islands Marine National Monuments—and set aside an area the size of his home state of Texas, the largest swath of protected ocean on the planet.
