1) Khademhosseini begins by seeding a patterned slide with heart muscle cells 2) Guided by the pattern, the cells elongate until they resemble the cells in a living heart 3) After six days, the cells have formed “organoids” that beat on their own and may be removed from the slide 4) The organoids are embedded …
Ad Support : Nano Technology Netbook Technology News Computer Software A technique that implants nitrogen vacancies into diamond at a rate of thousands per second could be the scalable technology for quantum computers. The big advantage of these so-called nitrogen vacancies is that they’re easy to see (because they can be made to emit photons) which …
Applied Physics Letters- Super-resolution imaging using a three-dimensional metamaterials nanolens Super-resolution imaging beyond Abbe’s diffraction limit can be achieved by utilizing an optical medium or “metamaterial” that can either amplify or transport the decaying near-field evanescent waves that carry subwavelength features of objects. Earlier approaches at optical frequencies mostly utilized the amplification of evanescent waves …
Figure 1: Schematic diagrams of three types of quantum simulators: atoms (red) held in place by an optical field (green; top left); ions (yellow) aligned using an electromagnetic field (top right); and superconducting circuits (bottom). Iulia Buluta and Franco Nori of the RIKEN Advanced Science Institute present an overview of how quantum simulators may become …
1. Complete Genomics has a report in the journal Science describing its proprietary DNA sequencing platform, including analysis of sequence data from three complete human genomes. The consumables cost for these three genomes sequenced on the proof-of-principle genomic DNA nanoarrays ranged from $8,005 for 87x coverage to $1,726 for 45x coverage for the samples described …
From Pajamas Media: “What’s going to happen if al-Qaeda gets their hands on WMD?” “They already have,” the defense contractor said. Then he told the story of how, just last January, al-Qaeda in the Islamic Maghreb (AQIM) had bungled a WMD experiment using bubonic plague. (H/T instapundit) From the Telegraph and other sources around Jan …
Chris Phoenix has considered RepRap and cheap 3D desktop manufacturing devices and iterative improvements there as a path evolves into molecular manufacturing. The Reprap can produce its own circuit boards and desktop manufacturing can produce prototypes. I believe that in the near to mid-term the financial and societal impact will be with things like the …
The radical italian Kitegen wind power system appears to have funding of 15 million euro (announced not distributed). An interesting synergy is possible with large Kitegen systems and nuclear power plants. Kitegen systems could be co-located with nuclear power plants to help prevent any illegal airplanes from hitting the nuclear plant. (Kite flying would be …
Four atomic quantum dots are coupled to form a “cell” for containing electrons. The cell is filled with just two electrons. Control charges are placed along a diagonal to direct the two electrons to reside at just two of the four quantum dots comprising the cell. This new level of control of electrons points to …
By fabricating an optical cavity around light-emitting nanotube mirrors at the bottom and top, wavelengths were confined to the desired 1.55-micron communications frequency. IBM researchers see a development path to light emitting nanotubes with no waste heat and a way to create a superlattice array of tubes for silicon photonic chips for optical computers. EETimes …
