Feed Biofuels: More Than Just Ethanol->

As the United States looks to alternate fuel sources, ethanol has become one of the front runners. Scientists studied the greenhouse gas emissions and bioenergy of corn, hybrid poplar, switchgrass and other crops to determine the efficiency of various biocrops in terms of energy consumption and energy output.

Feed Behavioral Ecology: Late Breeding Female Birds Surprisingly Had More Offspring->

Starting to breed late in life is a bad idea if you want to maximize the number of offspring that you produce -- or so the theory goes. But doubt has now been cast on this hypothesis -- one of the biggest assumptions in behavioral ecology -- by researchers from the universities of Bristol and Cape Town and published in Current Biology.

Submission + - space weather(solar flare) -> concern 4 GPS &am

dispatch writes: "WASHINGTON — The Global Positioning System, relied on for everything from navigating cars and airplanes to transferring money between banks, may be threatened by powerful solar flares, a panel of scientists warned Wednesday...The cause for their concern, [David L. Johnson, director of the National Weather Service] said, was an unexpected solar radio burst on Dec. 6 that affected virtually every GPS receiver on the lighted half of Earth. Some receivers had a reduction in accuracy while others completely lost the ability to determine position, he said."

Submission + - Inside Mac Pro the Intel Xeon X5365 Quad-Core chip

setteB.IT writes: "According to Ruben P. Simpliciano (public relations for Intel) the 3 GHz quad core Xeon inside the Mac Pro is the X5365 model. If the price for each chip was right ($ 1,172 = 878 euro) the 44% of the price of an entry level Mac Pro with dual Quad-Core (3,980 euro) is due to the Intel processors.

Submission + - Solar power-cell breakthrough

An anonymous reader writes: Researchers from the Nanomaterials Research Centre at Massey University in New Zeeland have developed synthetic dyes that can be used to generate electricity at one tenth of the cost of current silicon-based solar panels. These photosynthesis-like compounds work in low-light conditions and can be cheaply incorporated into window-panes and building materials, thereby turning them into generators of electricity.

Promising costs nothing, it's the delivering that kills you.
