This is weird science. Researchers at Lawrence Berkeley National Laboratory have taken some normal bacteria and made them photosynthetic by adding cadmium sulfide nanoparticles. Cadmium sulfide is what makes the garden-variety photoresistor work. That’s strange enough. But the bacteria did the heavy lifting — they coated themselves in the inorganic cadmium — which means that they can continue to grow and reproduce without much further intervention.
Bacteria are used as workhorses in a lot of chemical reactions these days, and everybody’s trying to teach them new tricks. But fooling them into taking on inorganic light absorbing materials and becoming photosynthetic is pretty cool. As far as we understand, the researchers found a chemical pathway into which the electrons produced by the CdS would fit, and the bacteria took care of the rest. They still make acetic acid, which is their normal behavior, but now they produce much more when exposed to light.
If you want to dig a little deeper, the paper just came out in Science magazine, but it’s behind a paywall. But with a little searching, one can often come up with the full version for free. (PDF).
Or if you’d rather make electricity, instead of acetic acid, from your bacteria be our guest. In place of CdS, however, you’ll need a fish. Biology is weird.

Near Field Communication (NFC) enabled devices are starting to appear in our everyday lives. Shown in the picture above is the xNT (fundraiser warning), a 2mm x 12mm fully NFC Type 2 compliant 13.56MHz RFID tag encased in a cylindrical Schott 8625 bioglass ampule. It was created by [Amal Graafstra], who therefore aims to produce the world’s first NFC compliant RFID implant. The chip used is the NTAG203, which is (for the sake of simplicity) a 144bytes EEPROM with different protection features.
We can only start thinking of the different possibilities this chip will create in the near future, but also wonder which precedent this may set for future NFC enabled humans. Embedded after the break is the presentation video of xNT but also an interview I conducted with [Amal Graafstra], who has already been living for 8 years with RFID tags in each hand.

BioTac Artificial Skin Technology is sure to be a storm with Robotics Designers. Giving them the opportunity to add a third sense to there robotic marvels. Now they can have the sense of touch to go along with existing technologies of sight and of sound. Thanks to the technology coming out of the University of Southern California making this possible.
They have chosen to call their sensor BioTac, which is a new type of tactile sensor designed to mimic the human fingertip with its soft flexible skin. The sensor makes it possible to identify different types of texture by analyzing the vibrations produced as the sensor brushes over materials. This sensor is also capable of measuring pressure applied and ambient temperature around the finger tip, expect to see this technology in next gen prosthetics. Let us know your thoughts on it.

Okay, now we think [James] is just on a mission to see what he can build using the dollar store as his parts bin. This is the nearly finished replica of the cyborg skeleton from the Terminator franchise. It’s made mostly from things that cost $0.99.
Actually we’ve got that a bit wrong. [James] is really shopping at the £0.99 store but the concept is basically the same. He’s already shown us that he’s a pro at this with the arc reactor replica we recently saw from him. This time around a set of speakers donate their enclosures to build up the spinal column supporting the skull. Fittingly these are glued together using a hot glue gun from the store. The sides of the skull are carefully crafted from a set of four plastic bowls. The jaw comes together thanks to the corners of a plastic box’s lid. And finally the majority of the face is from a golden skull costume mask. Spray it all grey and pop in some LEDs for the eyes and he’s done it! He show’s off his final creation in the video after the break.

[Ryan] whipped up this robotic masquerade mask to wear to his wife’s art opening / masquerade party, and its pretty wild. The prominent feature of this mask is a scavenged lens assembly from a typical point n shoot style camera, which is still connected to its electronics so it can go through its off and self check functions. You cant see through it, but with moving parts and a red LED inside, it does create an awesome cyborg type appearance,
The movement of the lens assembly is triggered by a thermistor inside of the mask’s nose piece, warm air exhaled onto to it for a given period of time changes the resistance and is monitored by a micro controller, which seems to act like a toggle style switch.
While there is not a build log, parts list, or many details, the schematic is provided for you to look over if you want to try and make your own.

Earlier this year we were amazed when University of California researchers controlled a beetle via electrical implants. The video available at the time of the original report showed beetles tethered in place while electrical stimuli was applied via the chip. New video of free flight is has now been posted. Although the motion is rather sporadic, it is obvious that simple commands to start flight, stop flight, and turn left or right are having their intended effect. Check out this cyborg action after the break. Is DARPA one step closer to unleashing legions of insect warriors on unsuspecting masses? Continue reading “Radio controlled beetle flight footage”
[Jerry] lost his finger in an accident and has since added a prosthetic USB flash drive in its place. It’s making the best of a bad situation; there’s nothing wrong with a little voluntary cyborgization. At least it’s not as invasive as some of the implants we’ve seen before.
UPDATE: Here’s the entry on [Jerry]’s personal blog.
