In the search for the fuels of tomorrow... researchers are finding inspiration in the sea. Not in offshore oil wells, but in the water where blue-green algae thrive. The building blocks of blue-green algae – sunlight, carbon dioxide and bacteria – are being used by researchers at KTH Royal Institute of Technology in Stockholm to produce butanol, a hydrocarbon-like fuel for motor vehicles.
The advantage of butanol is that the raw materials are abundant and renewable, and production has the potential to be 20 times more efficient than making ethanol from corn and sugar cane. Using genetically-modified cyanobacteria, the team linked butanol production to the algae’s natural metabolism...
A bacterium that produces cheap fuel by sunlight and carbon dioxide could change the world... “One of the problems with biofuels we have today, that is, corn ethanol, is that the price of corn rises slowly while jumping up and down all the time and it is quite unpredictable... In addition, there is limited arable land and corn ethanol production is also influenced by the price of oil, since corn requires transport. Fuel based on cyanobacteria requires very little ground space to be prepared. And the availability of raw materials - sunlight, carbon dioxide and seawater - is in principle infinite” ... some cyanobacteria also able to extract nitrogen from the air and thus do not need any fertilizer...

The Sweet Tooth is now a Smart Tooth. It is so obvious to use a tooth as a sensor platform. It would also be able to tell if the bacteria levels where to high and annoy you into flossing ;)
The provider of SmartSource advertising services is installing the solution using Thinaire NFC-based technology for in-store promotional displays, to deliver video, recipes and social-networking links to consumers.
Marcus Taylor's insight:
Well it is interesting to see that there is a QR code there as well. Would be interesting to se if there was a tap feature to enhance the dynamic of the transaction like the one from Blendology.

Microsensors in your shoes compile data on where you go and what you do. Your workout clothes track your daily progress at the gym and tell you when to slow down or speed up. And as you sleep, a headband monitors your REM patterns.
The world's biggest online retailer Amazon is testing an idea to have drones deliver parcels within half an hour. While Amazon says the Jetson's inspired idea will fly, an Aussie start up is trying to beat them to it.
A single cell in our body is composed of thousands of millions of different biomolecules that work together in an extremely well-coordinated way. Likewise, many biological and biochemical reactions occur only if molecules are present at very high concentrations. Understanding how all these molecules interact with each other is key to advancing our knowledge in molecular and cell biology. This knowledge is of central and fundamental importance in the quest for the detection of the earliest stages of many human diseases. As such, one of ultimate goals in Life Sciences and Biotechnology is to observe how individual molecules work and interact with each other in these very crowded environments. Unfortunately, detecting one molecule amongst millions of neighbouring molecules has been technically impossible until now. The key to successfully detecting the single molecule lies in the conception and production of a working device that shrinks the observation region to a tiny size that is comparable to the size of the molecule itself, i.e. only a few nanometres.
Researchers at the Fresnel Institute in Marseille and ICFO-the Institute for Photonic Sciences in Barcelona report in Nature Nanotechnology the design and fabrication of the smallest optical device, capable of detecting and sensing individual biomolecules at concentrations that are similar to those found in the cellular context. The device called "antenna-in-a-box" consists on a tiny dimer antenna made out of two gold semi-spheres, separated from each other by a gap as small as 15nm. Light sent to this antenna is enormously amplified in the gap region where the actual detection of the biomolecule of interest occurs. Because amplification of the light is confined to the dimensions of the gap, only molecules present in this tiny region are detected. A second trick that the researchers used to make this device work was to embed the dimer antennas inside boxes also of nanometric dimensions. "The box screens out the unwanted "noise" of millions of other surrounding molecules, reducing the background and improving as a whole the detection of individual biomolecules.", explains Jerome Wenger from Fresnel Institute. When tested under different sample concentrations, this novel antenna-in-box device allowed for 1100-fold fluorescence brightness enhancement together with detection volumes down to 58 zeptoliters (1 zL = 10E-21L), i.e., the smallest observation volume in the world.
The antenna-in-a-box offers a highly efficient platform for performing a multitude of nanoscale biochemical assessments with single molecule sensitivity at physiological conditions. It could be used for ultrasensitive sensing of minute amounts of molecules, becoming an excellent early diagnosis device for biosensing of many disease markers. "It can also be used as an ultra-bright optical nanosource to illuminate molecular processes in living cells and ultimately visualize how individual biomolecules interact with each other. This brings us closer to the long awaited dream of biologists", concludes ICFO researcher Prof. Maria Garcia-Parajo.
