Older image of nanoionic memory Scientists at Arizona State University have developed an elegant method for significantly improving the memory capacity of electronic chips. The researchers have shown that they can build stackable memory based on “ionic memory technology,” which could make them ideal candidates for storage cells in high-density memory. Best of all, the …
Experimental ECR-GDM Thruster As a Model for Fusion Propulsion by . Jerome J. Brainerd and Al Reisz A small experimental electric thruster, in which power is supplied via Electron-Cyclotron Resonance (ECR) absorption of microwaves by the propellant gas, has been tested at the NASA Marshall Space Flight Center (MSFC). The plasma generated is confined radially …
An electronic image shows six transistors installed in a space measuring 300 nanometres by 130 nanometres on a microchip developed by State-backed National Nano Device Laboratories Taiwan’s National Nano Device Laboratories in northern Hsinchu city said it had succeeded in packing more transistors into smaller chip space than anyone else so far. Nano injection lithography …
Chief Medical Correspondent Dr Sanjay Gupta and world-renowned anti-aging experts discussed practical steps for living longer, and cutting-edge research that could dramatically extend human lives. (for about 30 minutes) Geneticist Aubrey de Grey is the Chief Scientific Officer of SENS Foundation, which researches and promotes regenerative medicine. He said that techniques such as stem cell …
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. …
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 …
Test of relativistic gravity for propulsion at the Large Hadron Collider, 13 page pdf A design is presented of a laboratory experiment that could test the suitability of relativistic gravity for propulsion of spacecraft to relativistic speeds. The first exact time-dependent solutions of Einstein’s gravitational field equation confirm that even the weak field of a …
GE announced it has been developing a 1 Terabyte DVD size disk that can be read by a modified Blu-ray player. Peter Lorraine, GE’s lab manager, talking at an Emerging Tech conference last week, said that licence announcements could be expected soon. He also mentioned the notion of disks having the capacity of 100 Blu-ray …
A magnetic space launcher is proposed by Bolonkin. If this magnetic launcher costs 50 millions of dollars, lifetime of installation is 10 year and mountain is $2 millions of dollars per year. The launcher operates 350 days and launches 100 kg payload every 30 min (This means about 5000kg/day and 1750 tons/year). Then additional cost …
Ones and zeros: By depositing a ferroelectric material on top of graphene, researchers have coaxed graphene into holding on to two different levels of electrical conductivity, which could serve as bits 1 and 0 in computer memory. Credit: Barbaros Özyilmaz, National University of Singapore MIT TEchnology Review reports that researchers at the National University of …
At the Taiwan Open 2009 held in Taiwan from Feb. 10-13, the Dutch national supercomputer Huygens, which is located at SARA Computing and Networking Services in Amsterdam, defeated two human Go professionals in an official match. This is the second victory of Huygens playing Go against professional players. During the first two days of the …
