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.

These Klipsch Earphones Are Your Cheap-But-Decent Deal of the Day

If you want decent audio on the go and don't want a pair of clunky over-ear headphones, a great choice is the Klipsch S4i. $45 dollars nets you a pair of black Klipsch S4i earbuds with free shipping. This is the version with a remote and mic, and it usually retails for $60 and up elsewhere, and it's even priced lower than the remoteless version. If you had a feeling your stock earbuds weren't quite cutting it, today's a great day to give the S4i a shot. 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.

Bring the Drive-Thru to Your Kitchen with this Instant Breakfast Sandwich Tower

Breakfast sandwiches are one of the best ways you can start the day (taste-wise, at least). But they tend to be logistically difficult. Either you've got to take the time to carefully assemble one, or pay some scruffy, minimum-wage employee to make one for you. Hamilton Beach's Breakfast Sandwich Maker merges the best of both worlds.

A cleverly stacked arsenal of cooking-spaces, the Breakfast Sandwich maker makes multi-tasking a priority. The tower of chow cooks your egg in one compartment on the top, warms a slice of pre-cooked meat in the middle, and warms your cheese and other assorted fillings in a spot of the bottom. All between two English muffins for easy removal. And all this in five minutes or less.

Hamiliton Beach is releasing its breakfast baby into the wild later this month for the reasonable price of $30.  More here.

Can This iPhone 5 Case Really Boost Your Wi-Fi Reception?

If you're stuck with a limited iPhone data plan and rely heavily on Wi-Fi to avoid overage charges, spending $50 to vastly improve your reception when leeching from free hotspots might sound like a real bargain. That is, if the Linkase manages to deliver on its promise of boosting Wi-Fi reception by as much as 50 percent.

So how does it work? Well, that's a bit of a gray area that seems to border on snake oil. The case uses a technology called EMW—or electro magnetic waveguide—to boost your iPhone 5's signal snatching capabilities. But from the Linkase's website, that actually seems to be a combination of a case that prevents your fingers from touching and covering the iPhone's antenna, and an additional extending antenna that increases its reception prowess. Given this was the form factor for many handsets before the iPhone arrived, it's not that surprising that it works. But does anyone really want to go back to having something sticking out of their sleek handsets? More here.

Your 3D Printer Could Eat Empty Milk Jugs Instead of Expensive Plastic

Oh 3D printing. You're so glamorous. You're so cool. But, let's be honest, you're soooo expensive. Maybe instead of printing with $30 spools of plastic you could print with empty shampoo bottles and milk jugs. Oh, you can do that? See, this is why everyone loves you.

Researchers at Michigan Technological University have created a plastic extruder, called Filabot, that turns home recyclables into usable filament for 3D printing. Basically the machine takes 4-inch pieces of plastic and shreds them, before melting the plastic and extruding it through changeable nozzles, and shaping it for use in printers. Filabot works with thermoplastics like HDPE, LDPE, ABS, and NYLON, though PVC is out because of, you know, serious toxicity risks and stuff. The group calculated that Filabot uses a tenth of the energy needed to recycle empty bottles to produce its filament.

The first model, the Filabot Reclaimer, is in production now. The unassembled Filabot sold on Kickstarter for $350 so pricing will probably be in that range. This thing could really be worth it for avid 3D printers, and could drive down costs for hackerspaces and other groups. More here.

A Sailboat Napkin Holder Is the Most Clever Napkin Holder

This newly unveiled cork umbrella from Pelcor is lovely to look at but with the added, smug bonus of knowing your all-natural shield is renewable, too.

And for the burgeoning cork enthusiast, Pelcor has an entire collection of cork-based goods for your perusal. You can check them out right over here.

Reinforce Your Wardrobe With a Industrial-Strength Rebar Hanger

Is all your bad-ass clothing just too much for those flimsy, plastic, run-of-the-mill hangers. Do your pants or shirts, weighted as they are with pounds of pure awesomeness, need something more structurally sound to keep them in order? The "Man Hanger" suits your very strange needs.

Made from real, industrial-grade rebar, hand-bent into shape (somehow), and coated to prevent rust and corrosion, the Man Hanger is a marriage of strength and finesse fit to support those clothes that bring out both your softer side and your inner tough guy. That is, if you have any pants that fit that well.

Granted, "Man Hanger" is a god-awful name, and at $25 one Man Hanger is roughly twice as expensive as 40lbs of actual rebar (including shipping!), but unless you can bend steel, this is your only choice. Do you really need to drop that much on something that belongs in the closet and under clothes? Probably not. But damned if we don't want one. Or 12. More here.

$3,000 Gets You Literally the Aston Martin of Strollers

Sometime in the past few years mankind took a small step backwards in our development by allowing super-expensive luxury baby strollers to get popular. So popular, in fact, that now even Aston Martin is getting into the game by teaming up with Silver Cross on this over-the-top way to transport a baby.

Leather trim, aluminum-alloy wheels, air-ride suspension: these are usually features you only find on a luxury sedan, but have now made their way onto a vehicle designed to carry passengers who just randomly throw up all over the place. The Silver Cross Surf, Aston Marin Edition, is perfect for parents who want to ensure their kids grow up with an obnoxious sense of entitlement, and it's available exclusively from none other than Harrod's for just north of $3,000.

Charge This $20 Nokia 105 Phone Once Every 35 Days

The phone isn't intended to replace a smartphone. Quite the contrary—it's for emerging markets, aka countries where millions of people don't own phones at all, including China, Nigeria, India, and Indonesia. One charge has endurance for 12 and a half hours of talk time, but otherwise the Nokia 105 is very pared down. It basically just makes calls (over 2G), sends texts, and has a few games. Otherwise, it lacks a camera, has just a 1.4-inch display, and looks much like your very first Nokia brick phone from 10 years ago. But that's exactly what it's supposed to be, and that amount of talk time in a place where you probably don't have access to charge all the time is essential. And if we ever saw it in the US, it would be the ultimate burner phone. More here.

What’s the Best Remedy for the Hiccups?

Drink a glass of water upside down. Hold your breath until just before you pass out. Have someone scare the crap out of you. Everyone swears by a hiccup remedy. What's yours?

Obviously there's no wrong answer here. And it's not like there's any medication you can take when you get the hiccups. But what do you do to get rid of them?

You Can Make Gummy Bear Versions of Yourself

Somewhere in between the honor of getting a bronze statue of yourself and the shame of re-creating your sexual organs in plastic is this awesome gummy bear yourself service. You can basically create a gummy replica of yourself to eat. It looks absolutely delicious.

FabCafe in Japan is offering the service for approximately $65 (6,000 Yen), which sounds like a complete steal to me. It's apparently a 2-part process that requires a 3D body scanner and a lot of gummy colors. FabCafe, which made a chocolate replica for faces, is doing this for Japan's White Day (in Asian countries, White Day is like Valentine's Day but the girls give the gifts to the guys. Awesome).

Silicone Storage Bags Will Make You Wish Every Meal Was Leftovers

Storage containers for leftovers and other foods are usually designed to be cheap and disposable. But it turns out there's a better way. Silicone once again makes our lives easier with thesereusable, sealable storage bags that are safe to microwave, boil, or steam.

So instead of having to transfer last night's meatloaf into a microwave-safe container before reheating, you can simply store it in one of these silicone bags and then jam the entire thing in your magical hotbox for a piping hot lunch. They're also great for cooking, since the self-standing bags ensure liquids don't spill, but are still easy to pour once they're hot. At $20 per bag they're definitely more expensive than a box of Ziplocs, but with proper care they should easily last for thousands of meals. More here.
