James P. Gunderson, Ph.D., interviewed by Sander Olson Dr. James Gunderson is the Systems Architect for Gamma Two Robotics. He has been actively researching robotics for the past two decades. Gamma Two Robotics has created two robots with “cybernetic brains” – computers that allow the robot to react and alter their behavior based on various …
Another research paper that describes an aspect of how the Dwave System adiabatic quantum computer works. Synchronization of multiple coupled rf-SQUID flux qubits (10 page pdf) A practical strategy for synchronizing the properties of compound Josephson junction (CJJ) radio frequency monitored superconducting quantum interference device (rf-SQUID) qubits on a multi-qubit chip has been demonstrated. The …
Spaceshiptwo is being unveiled today and should soon result in thousands of trips from a spaceport to suborbital 60+ mile height and then return to the same launch point for $200,000 per trip This is laying the groundwork for global high-speed air and space travel with two hour flights anywhere in the world (where there …
In terms of the scale of the effort for colonizing North America, I think it is useful to compare the size of the naval fleets of the time and other historical benchmarks. We know how large the military is today and the share of the total economy that it has. It will be more useful …
UC Santa Barbara researchers have demonstrated the ability to electrically manipulate, at gigahertz rates, the quantum states of electrons trapped on individual defects in diamond crystals. This could aid in the development of quantum computers that could use electron spins to perform computations at unprecedented speed. Using electromagnetic waveguides on diamond-based chips, the researchers were …
Photorealistic images of carpet cloaks (9 page pdf) Using home-built dedicated ray-tracing software, we simulate photorealistic images of sceneries in three dimensions including dielectric carpet cloaks – i.e., continuously varying refractive-index distributions that allow for invisibility cloaking of a bump in a metallic carpet. Results for the ideal and for a simplified cloak are shown. …
India’s first indigenously designed breeder reactor – which breeds more material for a nuclear fission reaction than it consumes – is being built by Bhavini at the Kalpakkam nuclear enclave. Lowering of the huge stainless steel main vessel — 12.9 metres in diameter and 12.94 metres in height, weighing 206 tonnes — is considered a …
Mark Jacobson has responded to Barry Brooks criticism of Mark’s proposed 2030 plan for complete powering of civilization with solar, wind and hydro power. Mark Jacobson is the Stanford professor who adds the CO2 from burning cities into his calculation of CO2 generated by nuclear power and the deaths from nuclear war from his calculation …
Semiconductor nanocrystals that can be readily mass-produced and retain efficient electrical conductance, which can be used for device manufacturing via inkjet printing and other solution-based processes. This makes them an attractive alternative to the large semiconductor crystals typically used in commercial solar cells and computer chips which are expensive and can make large-scale applications such …
High nutrients activate HIF-1 through the TOR-S6K pathway, which leads to increased ER stress and shortened lifespan. Other regulators such as PHA-4, SKN-1, AAK-2, DAF-16 and HSF-1 may function in parallel to HIF-1 to modulate DR-induced longevity phenotypes. A protein that plays a key role in tumor formation, oxygen metabolism and inflammation is involved in …
1. Scientists have found a way to make an almost limitless supply of stem cells that could safely be used in patients while avoiding the ethical dilemma of destroying embryos. Scientists at the universities of Edinburgh and Toronto have found a way to achieve the same feat without using viruses, making so-called induced pluripotent stem …
