U.S. customs officials must have a reasonable justification before snatching your laptop at the border and scanning through all your files for incriminating data, a federal appeals court ruled today.

The Ninth Circuit Court of Appeals ruled that Homeland Security's border agents must have "reasonable suspicion" before they can legally conduct a forensics examination of laptops, mobile phones, camera memory cards, and so on.

Today's opinion (PDF) is a limited -- but hardly complete -- rejection of the Obama administration's claim that any American entering the country may have his or her electronic files … Read more

As fashion fiend Tim Gunn likes to say, you can never go wrong with a classic black dress. And if it's fitted with 2,000 LEDs and broadcasts tweets in real time, all the better, right Tim?

Nicole Scherzinger took that fashion rule to heart when she showed up at a launch party for new British 4G mobile network EE last week wearing a haute couture gown that flashes like a light show on top while displaying scrolling tweets on the skirt below.

CuteCircuit, a London-based fashion company that designs interactive clothing, created the electronic dress especially for the … Read more

Italian artist Leonardo Ulian's mesmerizing piece "Technological mandala 02," doesn't look like the average sacred art commonly seen in Buddhism and Hinduism.

Ulian, based in London, created the mandala with hundreds of microchips, circuits, resistors, and other components found within everyday electronics.… Read more

For some people, old circuit boards and computer components needlessly fill up space, awaiting a proper sendoff to the electronics recycling facility. Italian artist Franco Recchia sees opportunity in those old parts, though, and instead creates fascinating miniature city skylines with the pieces of forgotten technology.

The artist covers an array of major cities, including New York, Chicago, Detroit, and more. In an interview with the Agora art gallery, Recchia reveals that he often finds parts in "trash heaps" and that it takes four different styles of welding to make the techno cities. … Read more

T-shirts have long been used to express opinions, assert individuality, and spread messages. The tshirtOS prototype is trying to become the first commercially available programmable, Internet-connected digital T-shirt.

The shirt is a joint venture between high-tech fashion company CuteCircuit and Scotch whisky maker Ballantine's. I'm not entirely sure what a high-tech T-shirt has to do with a venerable Scottish alcoholic beverage, but I'm sure there's a marketing tie-in here somewhere.… Read more

Leaked from today's 404 show:

- 'People' defend Chic-fil-A on Facebook.

- Chick-fil-A cashier fired for racist receipts.

- Old records outsell new ones for the first time.

- Circuit City's in-home TV calibration is a total scam.… Read more

At least Best Buys still has its cell phone business.

On the heels of a disappointing quarterly report and today's resignation of CEO Brian Dunn, it's easy to think the entire company is doomed to follow in the steps of fallen electronic chains Circuit City and CompUSA. Yet its mobile devices business -- cell phones in particular-- has been impressively resilient during its recent troubles.

The cell phone business, which Best Buy has spent time and money building up, represents one of the rare bright spots in the company. Over time, Best Buy will likely be more heavily … Read more

Best Buy is on the same track that two former train wrecks were on, CompUSA and Circuit City.

Today, Best Buy reported a fiscal fourth-quarter net loss of $1.7 billion and announced it is closing 50 stores.

The basic pattern that CompUSA (closed brick-and-mortar stores in 2007) and Circuit City (closed stores in 2008) followed was: first select stores were closed, then more were closed, then all stores were shuttered or sold off.

Is this Best Buy's fate? And why? Below I try to offer some reasons for Best Buy's troubles based on my own experience and … Read more

The Geek Squad might not like this development, but we're excited about it. Engineers at the University of Illinois have developed a self-healing system for electronics that they say can restore conductivity to failed circuitry in "mere microseconds."

Today's ever-denser chips face more reliability problems due to the increasingly sophisticated demands on electronic devices. When one circuit within an integrated chip fails, the whole chip, and even the whole device (and your pressing deadline, of course) can go down with it.

"In a multilayer integrated circuit, there's no opening it up," Nancy Sottos, a professor of materials science and engineering at the University of Illinois at Urbana-Champaign, said in a statement. "Normally you just replace the whole chip. It's true for a battery too. You can't pull a battery apart and try to find the source of the failure."

To get around the need for external intervention and diagnostics (which may not be readily available for spacecraft or defense-based aircraft, for example), the researchers adapted a previous technique they'd developed for self-healing polymer materials.

They placed tiny microcapsules (as small as 10 microns in diameter) filled with liquid metal on top of a gold line functioning as a circuit. When the circuit cracks, the microcapsules break open, releasing the liquid gallium-indium alloy into the gap and restoring electrical flow--up to 99 percent in most cases. The liquid does its bidding in less time than it takes to blink. … Read more
