  The days of climbing atop your roof, wrapping yourself in tin foil and striking a techie yoga pose just to get a better wireless signal may soon be coming to an end. Anthony Sutera, spoke recently at Google's "Solve for X" event where he introduced the company's spray-on coating that can not only boost phone reception but can turn just about anything into an antenna. The aerosol spray coats an object's surface with thousands of nanocapacitors and spray-on particles that can turn a wall -- or even a tree -- into a transmitter. Full story at Discovery News.

Federal law requires increasing volumes of renewable fuels to be blended with the nation’s fuel supply. This year, the requirement includes the use of more than 13 billion gallons of corn-based ethanol nationwide. Ethanol is more expensive to make than gasoline and must be sold at a loss or subsidized unless consumers are willing to make up the difference. Anderson found that…

The researchers found that by blocking the activity of the protein kinase PKMzeta at the neuronal…
