This deep sea snail is covered in spikes, has purple blood and lives in the most extreme ocean environments. So of course the scientists that discovered it had to name it after their favorite punk rocker, Joe Strummer of The Clash.

In a study cleverly named “Molecular taxonomy and naming of five cryptic species of Alviniconcha snails (Gastropoda: Abyssochrysoidea) from hydrothermal vents,” researchers at the Monterey Bay Aquarium Research Institute detail five new species of snails, one of which gained the scientific name A. strummeri to honor The Clash frontman.

An iPad filled with apps weighs more than one with nothing installed

An iPad filled with apps weighs more.

An iPad filled with apps weighs more.

Which weighs more? An iPad filled with media and apps, or an iPad with no media or apps installed?

It sounds like a trick question — the digital age equivalent of “What weighs more, a pound of feathers or a pound of rocks?”

But surprisingly, an iPad without anything installed on it does weigh less than an iPad that is full.

RoboRoach Lets Kids Turn Real Cockroaches Into iPhone-Controlled Cyborgs

roboRoachGoRight

Robots are pretty cool, but have you ever wanted to create your own iPhone controlled cyborg? Backyard Brains is banking that a lot of kids are interested in cyborg technology and neuroscience (ethical dilemmas be damned), so after three years of R&D they’ve come up with the RoboRoach – a small electronic surgery kit that lets you turn a real-life cockroach, into an iPhone-controlled cyborg for a few minutes.

The kit comes with a backpack that contains a battery and receiver you superglue to the cockroach after sanding down a patch of shell.  You have to jab a groundwire into the cockroaches thorax, and then after that you carefully trim the antenna so you can stick some small electrodes onto both of them and receive signals from your iPhone. Don’t worry, the iPhone app and the cockroaches come free with the $99 kit, so you don’t have to go hunting for some behind your supermarket’s dumpster.

Vaavud Wind-O-Meter Measures, Magically, With Magnets

Vaavud-Closeup-carbon

Usually when we mention a Kickstarter project it’s with a mixture of excitement (because it’s like a totally cool product) and disappointment (because it will usually be at least half a year before we see a product, if ever).

However, some of these products make it into stores. The Vaavud is one. It’s a no-power wind-meter which you can buy today.

Scientist Transforms iPhone Into A Microscope Using Lens That Only Costs 7 Bucks

iphonemicro_2509363b

All it takes is some double sided tape and a $7 lens to turn your iPhone into a microscope

Add microscopes to the list of things your iPhone can replace. A group of scientist visiting Tanzania were able to convert their iPhone 4S into a microscope using nothing by a $7 lens, some double sided tape, and a torch.

After macgyvering the iPhone 4S into a microscope, the scientest then used it to take pictures of stool samples to determine the presences of eggs in some schoolchildren. Amazingly, the iPhone picked up 70 percent of the infections.

Photojojo’s $20 iPhone Polarizer, And Why You Want It

Photojojo’s $20 iPhone Polarizer, And Why You Want It

Question: What’s the only (non-gimmicky) photographic filter that can’t be duplicated in software? That’s right, you smart genius you! It’s the polarizer. A polarizer will do two things for your photography: it’ll increase the saturation of the colors in your pictures, and it’ll cut out unwanted reflections from glass and water. And Photojojo will now sell you one that’ll clip right onto your iPhone.

New From Microsoft: Multitouch In Mid-Air

New From Microsoft: Multitouch In Mid-Air

Wave your hands in the air like you just don’t care

Researchers in the UK have put together a prototype wrist-worn sensor that turns your own hand into a 3D movement controller for almost any device you can think of.

Experts from Newcastle University and the Cambridge-based Microsoft Research used off-the-shelf parts to assemble a sensor that straps to your wrist and detects movement of your arm, hand and fingers. There’s no need for any external sensor, nor for line-of-sight to the device you’re controlling. Everything’s done using the technology you wear.

Here’s a video that explains more.

How Super Algorithms Will Make Future iPhones & iPads Charge Twice As Fast

How Super Algorithms Will Make Future iPhones & iPads Charge Twice As Fast

Plug in your iPhone or iPad and charge it up, and you’ll notice that while the first 80% or so will go by pretty fast, they actually kind of suck at charging up that last 20%, taking a lot more time to do so than it feels like they should.

There’s a reason for this. Charging batteries up to “full” is a complicated process. There’s no real way to tell if a battery is completely “full” so all you can do is measure the voltage, which (and this is a vast simplification) tells you how much resistance is being met when you try to put more electricity into the battery.

That’s why it takes so long for an iPhone to charge that last 20%. It charges full blast until it measures a certain voltage, then goes into what’s called “trickle mode” to slowly allow small sips of electricity into the battery until it thinks, based upon some software calculations, that the battery is more or less full. But a new algotihm could make the time it takes to charge your iPhone or iPad go by a lot faster.
