Spinal cord stem cells could enable new paralysis treatment

A researcher at MIT’s Picower Institute for Learning and Memory has pinpointed stem cells within the spinal cord that, if persuaded to differentiate into more healing cells and fewer scarring cells following an injury, may lead to a new, non-surgical treatment for debilitating spinal-cord injuries. Their results could lead to drugs that might restore some …

YCBO superconductor at 105K and upcoming 195K superconductor

Superconductors.org reports the critical transition temperature (Tc) of the industrial superconductor YBCO (YBa2Cu3O7) has been successfuly increased from 92K to near 105K by reformulating to Y3Ba5Cu8Ox. No new elements were added. Y-358 – dubbed “Ultra YBCO” – is a novel intergrowth incorporating two different types of planar weight disparity (PWD) and a larger unit cell …

DNA sewing machine

DNA sewing machine created by Kyohei Terao from Kyoto University and colleagues. They designed laser-directed microdevices to pick up and manoeuvre giant individual molecules of DNA. The technology will also be useful for a number of other applications including DNA sequencing and molecular electronic. This should help enable the goals of $10-1000 whole genome sequencing …

Anton, special purpose supercomputer for molecular simulations

A special purpose supercomputer, Anton, is being made to accelerate the modelling of protein folding and provide a thousandfold increase in performance for complex molecular simulations. The effort is being led by David E. Shaw, a billionaire computer scientist. In the 1990s, Mr. Shaw was one of the most successful of an elite group of …

Advances toward quantum control: better trapped ion quantum gates, hybrid molecules in silicon, quantum coral

The new molecule is a hybrid, with the naturally occurring arsenic at one end in a normal spherical shape and a new, artificial atom at the other end in a flattened, 2-D shape. By controlling the voltage, the researchers found that they could make an electron go to either end of the molecule or exist …

Agile MEMS robots 100 times smaller than previous robotic designs

Duke university makes new MEMS (microelectromechanical system) based robots. Each microrobot is shaped something like a spatula but with dimensions measuring just microns, or millionths of a meter. They are almost 100 times smaller than any previous robotic designs of their kind and weigh even less. The devices are about 60 microns wide, 250 microns …

IEEE Spectrum : The Singularity a Special Report

IEEE Spectrum has a special report on the Singularity with contributions from several authors. Vernor Vinge first postulated the concept of a technological Singularity and he has an essay “Signs of the Singularity” and a video “How to Prepare for the Singularity” Richard Jones has an article “Rupturing The Nanotech Rapture”, but the essay criticizes …

Polymer containers could deliver enzymes to human cells

New Scientist reports on 200 nanometer polymer spheres that can get placed into living cells Nextbigfuture assumes that they could change the size to bigger to place larger amounts of material into cells. Human cells are about 20 microns across. Mitocondria are 1–10 micrometers across. Aubrey de Grey has indicated :if this works in vivo. …

Breakthrough in Waferscale self-assembly of nanostructures

Researchers at Northeastern University have developed a technique to scale-up the directed assembly of single-walled carbon nanotube (SWNT) networks, from microns to inches, creating a viable circuit template that can be transferred from one substrate to another for optimum productivity. The revolutionary assembly process has the potential to change the way electronics and other applications …
