Hasta La Gadget!

Salt: sure, you might use it to cure meats for your latest solar-powered circumnavigation. But hold onto your kippers, Magellan, because Singaporean scientists have found that sodium chloride — ordinary table salt! — can also dramatically increase storage capacity. You see, typical hard drives have randomly-arranged magnetic grains, which allow data density of about 0.5 terabit per square inch. But a high-resolution e-beam lithography process, aided by our good friend NaCl, arranges the grains in a tighter, more orderly fashion, upping the density to 3.3 terabits per square inch. Called nanopatterning, this technique enables a 1TB drive to hold 6TB without additional platters; it also works with current manufacturing technology, meaning no expensive upgrades. If that’s got you dreaming of a higher-capacity future, hit the source link for more glorious technical details. We’ll warn you, though: the pictures of luscious, bee-stung lips stop here.

Salt enables six times the storage capacity for snail-unfriendly hard drives originally appeared on Engadget on Mon, 17 Oct 2011 05:22:00 EDT. Please see our terms for use of feeds.

Faster delivery is always better when it comes to pizza, Thai food and now… drugs? Doctors seem to think so as they’re experimenting with a new method of delivering medicine to the bloodstream via tiny nanotubes powered by rocket fuel. By storing healing meds within the platinum-coated metal tubes, doctors have been able to propel the tiny vessels up to 200 times their own length per second — faster than swimming bacteria. It works as such: by introducing a hydrogen peroxide/water solution, the platinum reacts, sending it zipping forward and catalyzing the peroxide into water and oxygen. The downside? Even though the fuel is only .25 percent peroxide, it’s still slightly toxic — so it looks like it’s back to the drawing board until they can develop a safer alternative. Spiders, perhaps? Check out the video demonstration after the break.

There are plenty of reasons to want to monitor what’s going on in the ocean, from whale migration, to the recent stylistic resurgence of hot crustacean bands. There are certain inherent difficulties, however, in creating a powerful underwater microphone, namely all of that water you’ve got to contend with. A team of scientists has taken cues from the design of orca ears, in order to develop a powerful microphone that can work far beneath the waves. The researchers developed membranes 25 times thinner than plastic wrap, which fluctuate as sound is made. In order to operate at extreme depths, however, the microphone must fill with water to maintain a consistent pressure. So, how does one monitor the minute movements of a membrane hampered by the presence of water? Lasers, of course! The hydrophone can capture a 160-decibel range of sounds and operate at depths of 11,000 meters, where the pressure is around 1,100 times what we’re used to on earth. So if the orcas themselves ever master the laser, at least we’ll be able to hear them coming.

In theory, metamaterials are all kinds of awesome — they can boost antenna strength, focus lasers, and create invisibility cloaks. But, they’ve been limited to day dreams lab experiments because producing the light-interfering materials in any practical quantity has been difficult and time consuming. John Rogers, a professor at the University of Illinois has figured out a way to print a layered, nano-scale mesh that bends near-infrared light in much larger amounts than previously possible. The new method, based around a plastic stamp, has been used to create sheets of metamaterial measuring a few square inches, but Rogers is confident he can scale it up to several feet. Who knows, by the time the second installment of The Deathly Hallows hits theaters in July you could get the best Harry Potter costume — one that lets you sneak in without shelling out $13.

As you may know, crafting a katana is a delicate process that involves carefully constructing a razor-sharp high-carbon edge around a soft shock-absorbent core. One day though, smiths and forging fires could be replaced by electrode-wielding mad-scientists, with the technology to selectively harden and soften metal at will. At least that’s what we envisioned when we read about Jörg Weißmüller’s breakthrough research in the field of nanomaterials. The German scientist discovered that by placing precious metals in acid he could create tiny ducts through corrosion. Once those channels are flooded with a conductive liquid, electrical currents can be used to harden the material and, if you change your mind about the brittle results, the effect can easily be reversed to make it soft again. The tech could eventually lead to self-healing vehicle armor or scratch-resistant cellphones — but, really, we just want to zap our way to a high-quality samurai sword.
