Here Are the Samsung Galaxy S IV’s Guts

Samsung is just about to announce the Galaxy S IV but the same Chinese site that showed us in clear detail what the S IV will look like on the outside has decided to pry open the giant superphone and expose its innards too. An 8-core processor, 13 megapixel camera and motion detector too. You can peep all the guts here.

These Earbuds Will Make It Look Like a Pencil Is Sticking Through Your Brain

When someone puts on earbuds, they're pretty much telling the rest of the world to not bother them. It's the universal symbol for shut the hell up. But if someone put on this Magic Pencil earbuds? That's a conversation starter. I mean, these earbuds make it look like a pencil has been stabbed in one ear and out the other. They're hilarious!

I'd totally extend this motif and get an arrow, a knife, a sword, a lightsaber and whatever else long and slender object to make it look like my brains been sliced. $50 at Fancy. More here.

Build This Lego Leica M9-P Hermes and Save Yourself $49,962

Lego master builder Chris McVeigh has cooked up a playful alternative to Leica's obscenely and pointlessly expensive $50,000 M9-P ‘Edition Hermès'. The Lego version doesn't actually take photos, but you'll also pay only $38 for a kit if you can't scrounge all the parts needed to assemble it.

Or, if your Lego stocks already have every piece you need, you can save yourself even more money by just downloading the PDF build instructions McVeigh has kindly provided on his site. Oh and if you don't like the Hermes Edition, you can always build the standard model by just switching up your color palette. More here.

Adding Spinning Dials To a Rubik’s Cube Is Downright Evil

Unless you're some kind of prodigy who can solve one while juggling, making pancakes, and whistling Dixie, the Rubik's cube is already difficult enough. So why on earth would someone go and add a numbered, spinning dial to each side? That's just sadistic.

You could argue that Brando's $80 Roulette Wheel IQ Cube is actually a simpler version of the standard Rubik's Cube since it only features four segments per side. But it's the addition of that dial that takes the difficulty level from child's play to Mensa challenge. However, no matter how scrambled it might become, as long as these manufacturers keep cheaping out and using decals instead of paint, it's just a couple of hours of peeling and re-sticking to easily 'solve' it again.

Clip-On Recorder Simplifies Everything But the Legality Of Recording a Phone Call

Recording a conversation on your smartphone isn't as easy as you think it would be. Varying state-by-state laws make the legality a bit of a gray area, and if you don't have access to the free Google Voice service, you're going to have pay a monthly fee to capture a call. Or, put up with the U2 Mobile Recorder hanging off your handset.

In a round-about way the $134 U2 Mobile Recorder simplifies the act of recording a call on your iPhone or Android-based device. You just plug it into the top-mounted headphone jack of any phone except the iPhone 5, and hit record. Four gigs of non-expandable storage should be able to hold up to 144 hours of conversations, and a USB port allows the recordings to be dumped off to your PC. It's also got its own headphone jack for immediately transcribing a conversation, and on a single charge it can record or play back for about 20 hours. Which is perfect for even the most long-winded of snitches. More here.

Electronic Sensor Tattoos Can Now Be Printed Directly Onto Human Skin

Thanks to the same people that brought us the stick-on electric tattoo and stretchable battery, we're now looking at a future of electronic sensors that can be printed directly onto human skin.

At least for now, it seems like the sensors will be mainly used for medical purposes; they'll be able to monitor skin hydration, temperature, and any electric signals from muscle and brain activity. And unlike their stick-on precursor, these skin-printed tattoos don't use the easily-washed-off polymer backing, which as it turns out, wasn't even necessary in the first place.

Instead, the Rogers research group at the University of Illinois at Urbana-Champaign found that, by printing the electronic mesh directly onto skin, the sensor (which is held together and remains flexible thanks to special serpentine wires) becomes 1/30 the size and even conforms better to that body's natural bumps and curves. With the help of a "very robust" spray-on bandage, that sucker has a good two weeks before it begins to flake off. Of course, a longer shelf-life would require embedding the device underneath the top layer of skin, just like a real tattoo. In which case—uh oh—I'm pretty sure I know how that movie ends.

Still, with these advances and the current massive interest in wearable, body-monitoring tech, it's only a matter of time before health-tracking diehards demand taking wearable to within. What's more, these sensors could even be hooked up to interact with any number of external devices. The possibilities are truly exciting, and in a certain light, mildly terrifying. But whether we're ready for it not, the future, it seems, is here. More here.

A Snail USB Drive Is the Most Adorable USB Drive

The 8BG drive is $22. At first glance, you don't even really expect it to be a tech accessory. It's all one piece—the mouth of the critter is the cap on the drive, so you don't need to worry about losing the top, which always seems to get away. It's functional, and more importantly, very adorable. More here.

4-In-1 Measuring Spoon Leaves You One Thing To Wash

On one hand, the Dash 4-in-1 measuring spoon from Umbra reduces drawer clutter, leaves you with just a single tool to wash, and looks pretty snazzy in the process with its avocado finish. On the other hand, if you've multiple ingredients to measure, particularly wet ones, at some point you're going to probably end up getting your hands dirty touching this. Then again, at $8 a pop you can always just buy two. More here.

The Science of Aging

Carry a Tiny Supernova In Your Pocket With the Ultra-Bright LED Lenser F1

You might think all flashlights are created equal, but don't tell that to a flashaholic. There are large online communities of flashlight aficionados who take their illumination very seriously, and there's a good chance even they'll be impressed by LED Lenser's new F1 which manages to squeeze a whopping 400 lumens from a single CR123 battery.

It's true that CR123 batteries aren't as easy to find in stores as regular old AAs, but it's a fair trade-off. What you sacrifice in convenience, you gain in longer runtimes and greater illumination. CR123 batteries use a lithium-cell inside instead of alkaline, and output three volts instead of the 1.5 volts from a AA battery. So it allows flashlights like the F1 to blast an impressive 400 lumens while still boasting excellent battery life.

Of course you don't have to run the F1 at full power. You can extend its battery life even further by dimming its LED bulb to its lowest setting. But if you're going to drop $80 on it, you might as well go big or go home. More here.

Flexible Flat-Pack Furniture That Actually Looks Pretty Comfy

What you gain in convenience when opting for flat-pack furniture from stores like Ikea, you lose in comfort. But with a clever enough design, it turns out that your flat-pack seating can actually look comfortable and inviting—as South Africa-based Wintec's Stratflex line demonstrates.

At first glance it's hard to believe these contoured curvaceous pieces actually came from a box. But thanks to the use of strips of flexible polymer embedded in the various panels, when disassembled all of the various components will lie completely flat. And by incorporating grids of the flexible polymer into the surfaces where people sit, the seats are actually just as easy on your butt as they are on your eyes. Now if they only didn't range in price from $185 for a simple chair, to $1,500 for a three-person love seat. More here.

The World’s Smallest Automatic Umbrella

The Weather Channel reporters, with all their talk of Doppler radars and satellites and fear mongering weather graphics, are, in the end, just a bunch of liars. They may say you're in for sunny skies, but just hours later you'll find yourself beneath a torrential downpour, umbrella-less and unprepared. Hammacher Schlemmer has finally found a solution to the unreliable virus that is The Weather Channel in the form of the pocketable, keep-it-with-you-at-all-times World's Smallest Automatic Umbrella.

Measuring in at a mere 8 inches long when fully closed, the teeny tiny umbrella can actually open up to a full 40 inches in diameter, shielding you from whatever the heavens hurl your way. And from the look of its guts, small doesn't have to mean flimsy; it's packing a steel shaft, ribs, and stretchers that have—supposedly—been tested to withstand winds better than other, even larger compact umbrellas. Although, given some of the crap out there masquerading as rain protection, that may not be saying much. Still, $30 isn't bad for a fully automatic, pocket-sized umbrella that you can keep on your person at essentially all times. More here.

Rats Communicate With Each Other By Sniffing

Next time you see animals sniffing in each other's presence, there might be more happening than you expect. New research suggests that a humble intake of breath actually allows rats to communicate with each other.

In a series of experiments, carried out at the Case Western Reserve University School of Medicine, researchers used radio telemetry recordings of nasal respiration to identify how rats reacted when others sniffed in their direction.

The results, published in Current Biology, suggest that when rats of a higher status sniff in the direction of other rats, subordinates decrease their breathing rate. The researchers claim it's akin to the rats saying "don't mind me." Daniel Wesson, the lead researcher, explains:

"We know that rats and other animals can communicate through vocalizations, physical contact, odors, and also visual displays. To find that there was an undiscovered form of communication these animals had been using right in front of us this whole time was truly a neat experience."

In fact, when smaller rats failed to lower their breathing rate, dominant rats would often attack them! All of which suggests that there is far, far more to the simple sniffing that animals do than we may have previously thought—and that might help us understand the complex communication systems used by animals more clearly. Dr Doolittle would be proud. More here.

A Graphene Antenna Could Give Us Wireless Terabit Uploads in One Second

Wireless uploads of big files take for-ev-er. But researchers at Georgia Tech Universityhave plans for an antenna made of crazy thin graphene that would let you transfer a whole terabit of data in just one second.

Within a couple of feet, researchers could move a terabit per second, but in theory, from a closer range, you could move as much as 100 terabits a second. That's about 100 high-def movies in less time than it takes you make a cup of coffee. Graphene, you crazy.

MIT Technology Review explains how the antenna would be made:

Graphene could be shaped into narrow strips of between 10 and 100 nanometers wide and one micrometer long, allowing it to transmit and receive at the terahertz frequency, which roughly corresponds to those size scales. Electromagnetic waves in the terahertz frequency would then interact with plasmonic waves-oscillations of electrons at the surface of the graphene strip-to send and receive information.

Of course, this is just the preliminary groundwork on a piece of tech that doesn't exactly exist yet. Next the Georgia Tech group will have to figure out manufacturing, and how to make the necessary components—signal generators, amplifiers, and so forth—so the antennas will actually work. But the thought of lightning-fast wireless downloads is enough to be a little excited for the future. More here.

A Map That Shows How Salty the Seas Are

Some briny deeps are brinier than others. The Atlantic Ocean has two huge "deserts" of extra-salty water, the result of little rainfall and lots of evaporation.

These tangy tracts have been revealed by NASA's Aquarius instrument, which is aboard Argentina's Aquarius/SAC-D spacecraft and is dedicated to studying the salt content of the oceans.

NASA has just released the first year of data from Aquarius, running from December 2011 to December 2012. In the image above, red and orange areas are very salty, while green and blue areas are less so.

Patterns of salinity are expected to change over the coming decades as the climate shifts, with knock-on effects for major currents and regional sea level rise. More here.

Microsoft Might Owe Denmark More Than $1 Billion in Unpaid Tax

A new report by Denmark's national broadcasting corporation, DR, suggests that Microsoft owes the country over $1 billion in unpaid tax.

The report claims that Ballmer and co owe the Danish Treasury a total of 5.8 billion kroner, a hangover from the 2002 acquisition of Danish financial software company Navision. The OS giant sold rights to some of Navision's software to it Microsoft's Irish subsidiary at a suspiciously low price so that it could transfer valuable assets out of Denmark—where taxes are high.

Now, the Danish Treasury is chasing Microsoft all the way to Redmond to try and claw back billions in taxes and interest. It remains to be seen how successful that will be. More here.
