When you bend anything, you stretch the bonds between atoms and force the little fellas to move about against their will. This image shows exactly that happening, inside a sheet of glass.

Chalk one up for atomic force microscopy. As detailed in a paper published recently in the journal Science, researchers in China have used the imaging technique (as opposed to scanning tunnelling microscopy) to capture an image of a hydrogen bond for the very first time. As io9 explains, hydrogen bonding is common in nature — responsible for the properties of water and the link between the two strands of DNA’s double helix — and it’s something that chemists have long been able to visualize, albeit only on a theoretical level. According to Chemistry World, while there remains much to learn about the nature of hydrogen bonds, the researchers hope that this latest development will help lead to atomic force microscopy (or AFM) being used as a routine tool to examine molecules and offer a clearer picture of them.

After taking a few shadowy pictures for the scientific world’s paparazzi, the atom is now ready for its closeup. Today, a team of IBM scientists are bypassing the big screen to unveil what they call the “world’s smallest movie.” This atomic motion picture was created with the help of a two-ton IBM-made microscope that operates at a bone-chilling negative 268 degrees Celsius. This hardware was used to control a probe that pulled and arranged atoms for stop-motion shots used in the 242-frame film. A playful spin on microcomputing, the short was made by the same team of IBM eggheads who recently developed the world’s smallest magnetic bit. Now that the atom’s gone Hollywood, what’s next, a molecular entourage?

We’ve gotten pretty good at clocks. The nuclear clocks that exist right now are super accurate, so what more could you ask for? Something simpler. How about a clock that’s just one, single atom? That’s exactly what researchers just figured out how to make. More »

Sitting apart from the abundance of health-tracking apps and gadgets on display here at the CES 2013 Bluetooth SIG event is a toy made for the creative-minded geek: Atoms. Fueled by a successful kickstarter campaign, these intelligent building blocks veer away from the intimidating halo surrounding other DIY entries like Raspberry Pi which require a certain level of programming proficiency, allowing any user to pick up a kit, then plug and play. Color-coded according to their usage — blue for sensors, green for action and red for connectors — the modules offer users an ‘unlimited’ number of applications (think: weaving these into clothing).
But not everyone’s going to be brimming with ideas and to that end the company’s created four separate packages that’ll begin shipping in June. On the low-end, there’s a $29 prankster kit, which incorporates an exploding block, a $49 monster set that includes eight different modules, including one for voice recording and playback, a $59 magic wand set and, finally, on the high-end, a $79 iOS tank set. Compared to the number of pieces allocated to the cheaper sets, the two motors included in this latter iOS option may not seem like much, but it does also come bundled with a Bluetooth 4.0 brick and companion app for literal remote control. If you’re looking to dig deeper into the Atoms experience, you’ll be able to purchase each individual module à la carte. Unfortunately, you’ll have to wait until this summer to get your own hands-on with Atoms, but in the meanwhile, check out our gallery below and be sure to check back for a brief video demo.

This isn’t the view through your childhood kaleidoscope. Nor is it an alien craft come to beam you up. In fact, it’s the world’s first atomic force microscopy image of chemical bonds inside an individual molecule. More »

Researchers capture a single atom’s shadow, has implications for quantum computers
Posted in: Today's Chili 
A very small atom can cast a very large shadow. Well, not literally, but figuratively. Researchers at Griffith University have managed to snap the first image of a single atom’s shadow and, while the dark spot may be physically small, the implications for the field of quantum computing are huge. The team of scientists blasted a Ytterbium atom suspended in air with a laser beam. Using a Fresnel lens, they were able to snap a photograph of the dark spot left in the atom’s wake as the laser passed over it. The practical applications could improve the efficiency of quantum computers, where light is often used to transfer information. Since atoms have well understood light absorption properties, predictions can be made about the depth of a shadow cast, improving communication between the individual atoms performing calculations. The research could even be applied to seemingly mundane and established fields like X-Ray imaging, by enabling us to find the proper intensity levels to produce a quality image while minimizing damage to cells.
