Very Little Jogging Can Make Your Life Much, Much Longer

You probably go jogging because it makes you less fat and it is less humiliating than being yelled at through a 60-minute spinning class. But according to a new examination of the Copenhagen City Heart study, jogging less than two hours per week can add years to your life.

The Copenhagen City Heart study started in 1976, around the time that the jogging boom happened, and followed 20,000 men and women, aged 20 to 98. Of the group, there were 1,116 male joggers and 768 female joggers. When their mortality rates were compared with the main group, the men lived 6.2 years longer than non-joggers, and women 5.6 years longer. Even crazier? The amount of exercise needed to drastically increase your lifespan isn't much at all. Just one to two and a half hours per week, split over two or three sessions. More here.
Sure, folks who at least make the effort to run a little bit every week might also be taking care of themselves in other ways. The lesson? Stop being such a lazy turd. Or if you're already pretty active, you are probably going to live to be older than your lazy turd friends. Really, though, rippling abdominals aside, five or six years tacked on to the end of your life for a few hours' worth of effort a week is a pretty good deal.

Is This the World’s Most Expensive Bookmark?

You should never save your place in a book by laying it face down. When it's bookmarked that way, its spine breaks and the binding will never be the same again. But if you're reading next to this beautiful book table, you can probably get away with it.

Designed by German studio Voigt Dietrich, this table's design does two things very efficiently: it houses books while serving as a bookmark. Simply put the tome you're reading across its peak, and your page will be saved until the next time you want to read. The table also includes a flat surface for objects that need a level place to rest (like, almost everything.) More here.

Facebook's iPhone Messenger to get Video Chat, Enlarged Variant for iPad?

Been itching for Facebook's iPhone-dedicated Messenger app to make its way over to the iPad?  Maybe for the iPhone variant to finally reap the benefits of Skype video chat integration as well? Well, according to 9to5Mac, Camp Zuckerberg is testing both in-house, with the latter planned to hit iPhones this summer. 

According to the site, one of its trustworthy tipsters was able to grant it access to beta versions of the new apps, and it has the pictures to prove it. Unsurprisingly, the Messenger app for iPad is described as simply a sized-up port of the iPhone version, but surely the bump would be appreciated by many if it ever gets officially released. Perhaps more interesting, though, is having Skype video chat baked into the iPhone version -- tapping an arrow next to a contact initiates your video session, and9to5Mac reports that it's "smooth most of the time."

This Warm-Water Shower System Will Make Camping Considerably More Comfortable

Nemo Equipment's Helio Pressure Shower just might be the gear that finally gets me to go camping. This small, freestanding pressure-pump shower derives its heat from the sun and travels light at just about 2lbs all packed up.

Helio's foot pump and spray nozzle (which comes at the end of a 7-foot hose) provide a steady stream of pressurized water for your warm outdoor rinse-off—which, if its 11-liter bag is full, will last for between 5 and 7 minutes.

Just in time for camping season, The Helio Pressure Shower will be available this June. More here.

Sticky Protective Skin Lets You Mount Your iPhone Anywhere

Uguard.me's adhesive skins provide a more svelte alternative to bulky cases for protecting your phone. But they're also made with a special resin material that's slightly sticky to the touch. So they provide a bit of extra grip in the hand, and will actually stick to a smooth surface like a window.

Here's the kicker, though. The skin doesn't hold indefinitely. So while you could stick your phone to your car's window for some hands-free GPS navigation, it would only be a matter of time before it lost its grip and fell off. So it's best to think of these skins as a game of Cupertino Roulette that could end up costing you a lot more than just $20. More here.

Keep Your USB Thumbdrive Safe the Way the Ancients Did

Wax seals have been used for millennia to guarantee a document's authenticity. If you got a letter with an intact seal, you could be assured that what you're reading was legit. The Top Secret USB does the same thing for your digital documents—literally.

The Top Secret is a porcelain USB drive available in 2, 4, or 8GB models. Its casing includes a small indentation where, once sensitive documents have been loaded onto the drive, a small amount of molten wax is poured and imprinted with an intricate design from the included metal stamp. Once the wax cools, there is no way to open the drive and access the files without breaking the seal—your recipient can rest assured that they are receiving the unadulterated files. The Top Secret is currently available here and is available for $46 (2GB), $52 (4GB) and $59 (8GB).

Billionaire To Build Full-Sized Replica Of the Titanic

Just a few weeks after the 100th anniversaryof the Titanic's only voyage, Australian billionaire Clive Palmer has commissioned a Chinese shipyard to build a historically accurate replica of the colossal boat.

In addition to the Chinese builder, Palmer has hired a historical research team to mind all the details of recreating the nine-deck, 840-room cruise ship. The Daily Mail reports that like the original, Titanic II will have four towering smokestacks, but this time around they'll be entirely cosmetic. Instead of coal, Titanic II will be powered by diesel engines. Palmer says the ship will have gyms, spas and all the amenities people expect from luxury cruise ships. It'll also be outfitted with "21st-century technology"—presumably so that it doesn't sink on its 2016 maiden voyage.

At this time, Palmer says he has no idea how much the project will cost. We're taking bets on whether the bill will cost more than the political campaign Palmer also just announced. Yes,Titanic II Is obviously a stunt designed to promote Palmer's political career. But if you're going to spend a lot of money to get elected, you might as well build something huge and awesome.

Does Chewing Gum Make You Dumb?

If you thought that chewing gum helped you concentrate, it might be time to reassess. While some old research has suggested that it can help you with abstract reasoning and logic puzzles, new research reveals that it can completely screw up your short-term memory.

The new study, carried out at the University of Cardiff in the UK, pitted participants against classic short-term memory challenges, with and without gum. The tests had the volunteers attempt to recall lists of words and numbers in the order they were seen or heard, and also had them identify missing items from lists after they had been read out.

The researchers found that chewing seems to impair our ability to recall items in the correct order, and also makes us worse at suggesting missing items from a memorized list. While in the past researchers have suggested that chewing promotes blood flow to the brain, in turn improving cognitive function, the researchers from Cardiff have a different theory.

They suggest that the periodic action that is chewing gets in the way of repetitious cognitive tasks. If you try and memorize a phone number while tapping your finger, you'll find it much harder than if you're not tapping—and they suggest the exact same thing is true of chewing. In fact, they even performed an experiment along those lines, and found that both tapping and chewing gum had similar results on short-term memory.

This flies in the face of some previous studies, which have suggested that chewing gum canimprove your ability to reason through complex problems and solve logic puzzles.

But there's a fundamental difference between these two cognitive processes: memorizing and accessing lists from short-term memory uses completely different processes and parts of the brain to logic and abstract reasoning. Logic is handled primarily by the neocortex, while short-term memory is dealt with all the way over in the pre-frontal lobe. Perhaps most interesting, though, is that the most recent studies have shown that any improvement only lasts for 20 minutes at best, anyway.

What this all means for your future chewing is difficult to say with certainty. If you use your short-term memory a lot at work, it might pay to kick the habit. If you're thinking through abstract concepts all day long though, the occasional quick chew might give you the boost you need. More here.

Forget Graphene, Silicene Is Here to Blow Your Mind

Remember how graphene, the single-atom thick layer of carbon was so slick it was going to change everything? Well it looks likesilicene is here to steal the spotlight. Researchers have just made the first sheet of single-atom thick silicon.

Silicene has been a work in progress for years, but they think they've finally got it down now, and it represents a tremendous breakthrough. Graphene is awesome, but it's proven a bit tricky to work it into components. Because silicene is made of silicon, which most chips are already made of, the integration process could be much simpler.

Patrick Vogt of Berlin's Technical University in Germany, along side researchers at Aix-Marseille University in France managed to create silicene by condensing silicon vapor onto a silver plate to form a single layer of atoms. They then tested the sheet and found that it closely matched the properties silicene was theorized to exhibit. The next (challenging) step will be to grow silicene on insulating substrates so that it can be fully tested and evaluated for potential future uses in electronics. More here.

Siri Will Cause Your iPhone 5 to Self-Destruct

Hey there, future person, you've misplaced your iPhone 5. Some nefarious person is trying to break in and steal all of your naked pictures. Not to worry, you've programed Siri to self-destruct Mission Impossible-style after three incorrect login attempts. Boom.

I just feel bad for the guy that thigh-dials three wrong logins in his pants pocket.

Hate Itchy Mosquito Bites? Building Up an Immunity Only Requires About 15,000 Bites Per Year

Meet Steve Schutz. Some might say he's very dedicated to his work. But others would call him downright crazy. You see Steve works in an insectarium, a place where mosquitos are born and raised. And to ensure its residents are well-fed and propagate, he serves up his bare armonce a week for dinner.

As a result, after a feeding the 50 red welts on his lower arm barely even register as a slight tingle since Steve has built up an immunity to the mosquito's saliva. Over the past 12 years he's been bitten over 150,000 times, since the warm fresh blood is basically what the insects feed on out in the wild. And it's just a heck of a lot easier than preparing 50 tiny insect-sized baby bottles full of blood. But it's all in the name of science, since the lab where Steve works studies the effects of pesticides on the bugs, to test if, and how quickly, they become resistant.

Temperature Sensitive Rug Changes Colors To Match the Seasons

When you decorate a room you're stuck with a single color palette all year round that doesn't necessarily reflect the changing seasons outside. So maybe we should look toSiren Elise Wilhelmsen's color-changing rugfor inspiration on designing a room that reflects, or contrasts, the temperatures outside.

Wilhelmsen refers to her Season Carpet as a "soft thermometer" and it's made from 100-percent wool dyed with special heat-sensitive pigments that change color depending on the ambient temperature. The rug is actually made up of three different colors that all shift their hues at different temperature ranges, so the pattern should actually be fairly unique as it transitions throughout the year. Unless your home's thermostat always maintains the perfect temperature indoors. In that case the rug's not going to put on a show for you. More here.

Samsung Overtakes Nokia as the World’s Biggest Phone Manufacturer

Samsung has just toppled Nokia's 14-year run as the world's biggest vendor of mobile phones in terms of shipments. In the first quarter of 2012 Samsung shipped 93.5 million handsets—36 per cent more than a year earlier—overtaking the Finnish phone giant who shipped a mere 82.7 million.

Bloomberg reports that it's Samsung's smartphones that have driven its sales, as it shipped a massive 44.5 million of the things in the first three months of the year. By way of comparison, Apple shipped 35.1 million units in the first quarter.

Nokia has been the world's biggest seller of mobile phone since 1998, a title which it snatched from Motorola. Remember those days, Moto? More here.

You Can Buy This $195 Million US Navy Stealth Ship for Just $100,000

If I had $100,000 handy, I would bid for theSea Shadow, the stealth ship that DARPA built for the US Navy in 1983. It's now for sale at GSA Auctions. The original price tag: the US Government paid $195 million to Lockheed Martin to build it. And you get a HMB-1 Mining Barge too in the package too.

THE EX-SEA SHADOW (IX-529)
YEAR BUILT: 1983
BUILDER: LOCKHEED MARTIN
OVERALL LENGTH: 164 FEET
WATERLINE LENGTH: 118 FEET
EXTREME BEAM 68 FEET
WATERLINE BEAM: 58 FEET
MAXIMUM NAVIGATIONAL DRAFT: 15 FEET
DRAFT LIMIT: 15 FEET
LIGHT DISPLACEMENT: 499 TONS
HULL MATERIAL: STEEL HULL AND SUPERSTRUCTURE
DIESEL ELECTRIC PROPULSION SYSTEM
NUMBER OF PROPELLERS: TWO

Needless to say, this ship would be perfect is you want to be a superhero or a supervillain.

The price will keep going up, for sure. It started at $50,000. But it will not get anywhere its original price tag. The reason: the US Government doesn't want you to keep it in its original form. If you want to buy it, you will have to destroy it! It has to be converted into scrap. More here.

THE EX-SEA SHADOW SHALL BE DISPOSED OF BY COMPLETELY DISMANTLING AND SCRAPPING WITHIN THE U.S.A. DISMANTILING IS DEFINED AS REDUCING THE PROPERTY SUCH AS IT HAS NO VALUE EXCEPT FOR ITS BASIC MATERIAL CONTENT.

The Perfect Fashion Statement for Photographers

If you're stuck for a gift for your closest camera-lover, look no further. These bracelets are custom-made from old camera lenses, providing a one-off piece of jewelery that any photography nerd is bound to love.

Made by Craig Arnold in South Australia, each one is different, in no small part because they display the wear-and-tear suffered by the lenses when they were in active service. He even makes some sterling silver replicas of old camera parts—like lenses and aperture rings—to complement them.

Such a statement doesn't come cheap, however: the bracelets all cost upwards of $200. Maybe you could try and make your own instead? More here.

Wipe Your Hard Drive DoD-Clean

You can reformat and overwrite that old hard drive as many times as you want before junking it—modern forensics software can still extract data from it. The Drive eRazer Ultra, however, can expunge your sensitive data to DoD specifications.

The Drive eRazer Ultra by Wiebetech is a standalone device for securely erasing hard drive data. It works natively with SATA and IDE/PAT drives, clearing them by overwriting every bit with a 0—there's simply nothing left to recover from the plate.

The process is relatively speedy, averaging about 7GB/min for newer drives. Its Secure Erase mode—one of many available, including user-generated programs—eliminates data left at the end of partly overwritten blocks, directories, partitions, and Host Protected Areas. And unlike, say a degaussing machine or a comically-large magnet, the drive remains usable afterwards. More here.

These Magnetic Bike Lights Look Super Sleek

Bike lights are massively important if you're cycling anywhere after sunset, but attaching them to your bike is a pain in the ass. These lights could be the perfect solution—provided you ride a steel-framed bike.

Designed by Copenhagen Parts, they're made of machined aluminium and have a magnet on the rear. There's no on/off button: when you plop the light onto the frame, it immediately switches on. That massively speeds up the process of getting lights on and off your bike. Lars Thomsen, one of the designers, explains:

"We had the idea some time ago and have spent the last 18 months getting them right. We now have them perfected and will soon be ready to launch this patented innovation."

In fact, the prototypes have been in testing for six months, during which times Copenhagen Parts have added magnets strong enough to keep the lights in place regardless of road service. Though they're not quite on sale just yet, they should be available later this year and you can pre-order now. More here. 

Carbon Fiber Bookshelves Are Novel Objects of Lust

You don't see it used in furniture very often, but Davide Anzalone's Aliante bookshelf, which took the top prize at Olympus RFP's2012 Carbon Fiber Design Contest, makes a strong case for using carbon fiber everywhere.

Looking like it could serve alongside the stealth fighter in the U.S. Air Force, you can actually fill the shelf's outstretched tipped wings all the way to the ends without them sagging. And let's not forget that when it comes time to move you could easily strap this thing to your back and barely feel the added weight. If only such a creation didn't come with a price tag that would require you to mortgage your new home. More here.

Safety Pin Flash Drive

Art Lebedev's studio is best known for its flashy glowing Optimus keyboards, but the firm dabbles in other clever designs too. Like merging a USB flash drive with a safety pin creating four gigs of storage you're unlikely to lose.

There's no word on whether or not the Bulavkus flash drive concept will ever actually be available for sale, but Lebedev's studio has certainly put more elaborate creations into production. So there's hope that you might actually be able to get your hands on one someday, and keep your files as secure as a pair of mittens tethered to a child's coat sleeve. More here.
