Carnival of Space 120 is up at Music of the Spheres This site contributed the article on creating propulsion from the Mach Effect, which had information and an interview with Paul March, one of the main Mach Effect researchers. Southern Fried Science describes how space technology can be used to help the earth and its …
An 81 page pdf report from the energy Information Adminstration analysing the current Waxman Energy/climate bill The EIA projected that to keep the costs of implementing the bill low for consumers — about $339 extra per household in 2030 according to their basic scenario — nuclear energy use would rise from 8 quadrillion BTUs a …

The TASER company and the military are working together on the TASER Shockwave that combines a lot of TASER stun devices together for riot control and other purposes. Multiple TASER Shockwave units can be stacked together either horizontally in order to extend area coverage, or vertically to allow multiple salvo engagements; or daisy chained together …
1. It’s a cooker, a fridge and a generator in one — and it could have a huge impact on the lives of people in the world’s poorest communities. Two billion people use open fires as their primary cooking method. These fires have been found to be highly inefficient, with 93 per cent of the …
Nvidia projects that in just a few years Tegra, its embedded system on a chip (SoC), will account for more than half of income. Tegra has 42 total design wins, announced at the recent Computex show, including 18 smart phones and 18 customers for mobile Internet devices (MIDs). nVidia has an aggressive roadmap for Tegra; …
Step-by-step rotation of a molecule-gear mounted on an atomic-scale axis. Gears are microfabricated down to diameters of a few micrometres. Natural macromolecular motors, of tens of nanometres in diameter, also show gear effects1. At a smaller scale, the random rotation of a single-molecule rotor encaged in a molecular stator has been observed, demonstrating that a …
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 …
Darpa’s latest venture, called “Physical Intelligence” (PI) is to prove, mathematically, that the human mind is nothing more than parts and energy. In other words, all brain activities — reasoning, emoting, processing sights and smells — derive from physical mechanisms at work, acting according to the principles of “thermodynamics in open systems.” Thermodynamics is founded …
A prototype in-plane electrophoretic display consisting of 1,000 pixels. Credit: Philips MIT TEchnology Review reports A new approach developed by Philips now offers fresh hope for color e-paper displays that are so bright and clear that even traditional liquid crystal displays (LCDs) will pale in comparison. The new approach has the potential to create color …
Spaceward has a page on space elevator feasibility that looks at tether strength and power to weight ratio for the power system for the space elevator climber. Based on a gradual convergence of experimental and theoretical results, the specific strength of raw CNTs will not exceed 50 MYuri [1 Mega-Yuri = 1 N/Tex = 1 …
