Making Hydrogen From Waste Vegetable Oil

Researchers at the University of Leeds have found an energy-efficient way to make hydrogen out of used vegetable oils discarded by restaurants and other establishments. The process generates some of the energy needed to make the hydrogen gas itself and is also essentially carbon-neutral.

Should brain scans be admissible as legal evidence?

This week's question concerns brain scans and the legal system. In 2008 a judge in India convicted a woman of murdering her fiancee based partly on brain scan evidence that gauged her ability to remember details of the crime. And in the US, fMRI scans have already found their way into courtrooms and more attempts are on the horizon. In response, two psychologists and a law expert from Stanford University conducted a study to determine how much information about memories can be seen in brain activity. Using fMRI to scan the brains of healthy adults, the researchers were able to measure how strong their subjects' sense of a specific memory was; but they could not tell for sure whether the memories themselves were based on a recollection of an actual experience.

What do you think? Should brain scans be admissible as legal evidence?

Fish Schooling as a Basis for Vertical Axis Wind Turbine Farm Design

Most wind farms consist of horizontal axis wind turbines (HAWTs), but an alternative paradigm for wind energy extraction is found in vertical axis wind turbine (VAWT) designs. A single spatially-isolated VAWT has a significantly lower power coefficient.

Effects of Cerium Removal from Glass on Photovoltaic Module Performance and Stability

In recent years, better stabilizer formulations for ethylene vinyl-acetate have been developed, giving more confidence in the long-term stability of PV packaging materials. Because of this, some manufacturers have stopped using Ce-doped glass. National Renewable Energy Laboratory researchers studied Ce-free glass.

Was the discovery of Russian spies still operating in the US surprising?

This week's question concerns the recent discovery of Russian spies still operating in the US. In June, authorities uncovered a Russian spy ring of 10 individuals operating in New York and Cambridge. Last week, the US and Russian governments completed a "spy swap" in Vienna.

What do you think? Was the discovery of Russian spies still operating in the US surprising?
