Submission + - Shock Wave Disk Engine Can Triple Fuel Efficiency (inhabitat.com) 1

formaggio writes: Straight from the engineers at Michigan State University, this new ‘wave disk engine’ is 3.5 times more fuel efficient than a conventional combustion engine, can be run on almost any fuel and emits 95% less carbon dioxide.

Submission + - Virus-like Nanoparticles Can Stimulate Immunity (sciencedaily.com)

intellitech writes: Vaccine scientists say their "Holy Grail" is to stimulate immunity that lasts for a lifetime. Live viral vaccines such as the smallpox or yellow fever vaccines provide immune protection that lasts several decades, but despite their success, scientists have remained in the dark as to how they induce such long lasting immunity. Recently, however, scientists at the Emory Vaccine Center have designed tiny nanoparticles that resemble viruses in size and immunological composition and that induce lifelong immunity in mice.

Submission + - Frictionless Superfluid Found in Neutron Star Core (sciencedaily.com)

intellitech writes: NASA's Chandra X-ray Observatory has discovered the first direct evidence for a superfluid, a bizarre, friction-free state of matter, at the core of a neutron star. Superfluids created in laboratories on Earth exhibit remarkable properties, such as the ability to climb upward and escape airtight containers. The finding has important implications for understanding nuclear interactions in matter at the highest known densities.
