They make emergency calls, serve as a late night texting platform, and now in developing areas where money is tight and malaria runs rampant, they can serve as a microscope.

The DIY design is the brainchild of Aydogan Ozcan, an assistant professor of electrical engineering and member of the California NanoSystems Institute at the University of California, Los Angeles. He did it all with some software he wrote and about $10 in off-the-shelf parts, reports the New York Times.

There's actually no lens to speak of, as the magnification is handled entirely by software, holograms and electronics. This, Ozcan says, is what's at the heart of the device's portability and affordability. Better still, this means that a future system based on this design could have the ability to diagnose and research even better than a traditional microscope in the field. Said Bahram Jalali, an applied physicist and professor of electrical engineering at U.C.L.A in an interview with the New York Times, the beauty of the design is in its lack of mechanical scanning.

"Instead you capture holograms of all the cells on the slide digitally at the same time," he said to the Times. This makes it possible to "immediately see pathogens among a vast population of healthy cells." [New York Times]

<![CDATA[Microscope dSLR Lens Captures Both the Beautiful and the Terrifying]]> I thought this photo was of pollen. It's not. Really, those are the protrusions on a starfish at 66x magnification, captured on a dSLR.

Nikon Rumors reviewed the Nikon-compatible Fabre Photo EX DSLR Stereoscopic Microscope, a $1,600 lens that pwns macro photography pretty hard.

Here's a video they captured of a millipede. So gross, but we can't look away.

Two points Nikon Rumors makes: integrated LEDs sound handy for illuminating the small subjects, but they tend to create a harsh reflection on surfaces. And, yes, the microscope lens is every bit as "fun" as you'd imagine.

Lots more test shots over at: [Nikon Rumors]

<![CDATA[IBM Takes First 3D Image of Atomic Bonds]]> From what I remember of chemistry, molecules were presented on computer screens, or at the very least with dowels and balls. Thanks to this incredible discovery, however, I'm jealous of how tomorrow's engineers will view—and control—nature's building blocks.

Now, the picture above is pretty unremarkable, right? Black and white (trivia: molecules have no color), grainy, shot in the kind of out-of-focus manner you expect from a guy like me, who can't seem to venture out beyond the Auto setting on his entry-level Nikon D40 DSLR. But wait a second. Doesn't the image kind of seem, well, familiar? Like high school chem class familiar? Balls and sticks familiar?

Here's another image; a computer generated image that's much more at home for anyone who studied atoms and molecules in the dead and gone days of 1997:

Make sense now? That B&W structure is an actual image of a molecule and its atomic bonds. The first of its kind, in fact, and a breakthrough for the crazy IBM scientists in Zurich who spent 20 straight hours staring at the "specimen"—which in this case was a 1.4 nanometer-long pentacene molecule comprised of 22 carbon atoms and 14 hydrogen atoms.

You can actually make out each of those atoms and their bonds, and it's thanks to this: An atomic force microscope.

Like the venerable electron microscope, but more powerful and with an eye for the third dimension, the AFM is able to make the nano world something we humans can appreciate visually. Using a silicon microscale cantilever coated in carbon dioxide (tiny, tiny needle), lasers, an "ultrahigh vacuum" and temperatures that hovered around 5 Kelvin, the AFM imaged the pentacene in nanometers. It did this while sitting a mere 0.5 nanometers above the surface and its previously invisible bonds for 20 long, unmoving hours. The length of time is noteworthy, said IBM scientist Leo Goss in statement from IBM, because any movement whatsoever would have disrupted the delicate atomic bonds and ruined the image.

And that's the real beauty of this image. For the first time ever we can see where each of those carbon and hydrogen atoms line up, and the overall symmetrical shape they create. In 3D.

Quirky, Quarky, Quantum Computing

That IBM, a hardware company, was the entity to accomplish this feat should be fairly obvious, given what we know (and don't yet know) about quantum computing. Said an IBM representative in an email to me this morning, "This pioneering achievement and the new insights gained from the experiments extend the ability of scientists to study matter with atomic resolution and open up exciting new possibilities for exploring electronic building blocks and devices at the ultimate atomic and molecular scale-devices that might be vastly smaller, faster and more energy-efficient than today's processors and memory devices."

In a quarkshell, that means this discovery might help future engineers manipulate atoms and their bonds, as well as create powerful, energy-sipping quantum computers for their cryptography needs, space travel or maybe even large black and yellow rooms that make our fantasies come true (or at the very least allow androids to play Sherlock Holmes).

But not so fast, Einstein. I see that tabletop subspace communicator you've imagined on your desktop. It's a great idea, and while I understand your enthusiasm for such things, as Matt explained earlier this month quantum computing, entangled desktops and Star Trek holodecks are all decades away, if not more.

What this discovery does do however is advance our primitive understanding of the Way Things Are. It's a small, nanometer-sized piece in a puzzle that doesn't even have all the pieces on the table yet. Hell, we don't even know where all the pieces are yet. From the looks of these images though, we will someday soon. [Images: IBM]

<![CDATA[USB Microscope Digitally Magnifies at 200x, 1600x1200 Resolution]]> We've seen digital microscopes before, but few can claim that they have a 1600x1200 sensor, 200x magnification and 2 GB of free online storage. This £50 device works improves upon last year's 640x480 Microscope Pen from the same company, and lets you take stills or AVI movies.. And the test pics from the microscope don't look half bad (if they're actually real). The USB microscope can be found over at [IWOOT via Geek Alerts].

<![CDATA[Drawings of Early Microscopes Show Artistry in the Pursuit of Science]]> Ah, where would science be if not for the contributions of the humble microscope? Did you know that the development of the world's first microscope began in 11th century Iraq, when scientist and polymath Ibn al-Haytham recorded all sorts of data about lenses, binocular vision, mirrors and observable properties of light his The Book of Optics? That would make this pioneering technology more than a thousand years old. BibliOdyssey has amassed a great collection of drawings of pre-20th century microscopes and some of them look more like art pieces than instruments of science. Check out my favorites: [Bibliodyssey via MAKE]

<![CDATA[Scientists Develop Micro Microscope: Fits on a Chip, Costs $10]]> There's been a bit of a rush of pocket/USB digital microscopes recently, but none can hold a candle to this development from the clever chaps at Caltech. They've done a neat bit of thinking and redesigned how microscopes work: their new optofluidic microscope combines microfluidics and standard chip design, and floats samples over a pinhole-camera-like detector.

As the sample moves through a metallic microfluidic channel, either by gravity or drawn by an electric field, it passes over a line of sub-micron diameter pinholes, blocking or transmitting light (sunlight works fine). The dynamic light level is then detected by a standard CCD device behind the holes. So it's lens-free, working more like a micro-sized scanner device, and yet it has comparable image quality to a top-rate glass-lensed traditional microscope.

And it's about the size of a quarter in its entirety: making it small enough to fit into a mobile-phone-sized device, with an LCD screen. It's cheap—around $10—and easy to make, and would be perfect for developing countries for easy detection of malaria in blood and such. [Physorg]

<![CDATA[VersaCAM Tech Makes Scientists Really Happy]]> If it was your job to look through a microscope every day, you'd be thrilled with the new technology by JMAR. The VersaCAM is an all-digital scanning boom that will basically allow you to see more than just the usual small, flat objects on glass slides. Basically, it performs analysis of scanned images from samples that would never fit on a typical microscope. So you'll even be able to check out close up images of 3D objects in or out of your favorite laboratory. Science geeks, rejoice. Now you can inspect just about anything!
