GE and NASA to give open-rotor jet engine systems a spin

GE Aviation and NASA will run a wind tunnel test program over the northern summer to evaluate and test counter-rotating fan-blade systems for open-rotor jet engine designs. The newly improved rig for testing was originally used by GE and NASA in the 1980s on scale models of counter-rotating fan systems, which led to the development [...]

SCI: Engineers find way to build a better battery..

CHICAGO (Reuters) – U.S. engineers have found a way to make lithium batteries that are smaller, lighter, longer lasting and capable of recharging in seconds. The researchers believe the quick-charging batteries could open up new applications, including better batteries for electric cars. And because they use older materials in a new way, the batteries could [...]

ScI: Nasa launches Earth hunter probe

An unmanned Nasa mission to search the sky for Earth-like planets with the potential to host life has launched from Cape Canaveral in Florida.
The Kepler telescope will orbit the Sun to watch a patch of space thought to contain about 100,000 stars like ours. It will look for the slight dimming of light from [...]

Sci:HIV stays one step ahead of immune system

HIV, the virus that causes AIDS, is one of the fastest-evolving entities known. That’s why no one has yet been able to come up with a vaccine: The virus mutates so rapidly that what works today in one person may not work tomorrow or in others.
A study published Wednesday in the journal Nature confirms that [...]
