Where no smartphone has gone before

Star Trek's 'Tricorder' was an essential tool, a multifunctional hand-held device used to sense, compute, and record data in a threatening and unpredictable universe -- and it's no longer completely science fiction. A new invention may be able to turn smartphones into powerful hyperspectral sensors, capable of identifying the chemical components of objects from a distance.

New pain relief delivery method discovered
Wed, 01 Apr 2015 08:43:31 EDT
A new drug release gel, which may help avoid some of the side effects of painkillers such as ibuprofen and naproxen, has been developed by chemists looking for a way of eliminating the adverse side-effects associated pain-killing drugs, particularly in the stomach. The new gel, based on small molecules which self-assemble into nanofibers which could interact with a variety of anti-inflammatory, painkiller drugs, including iburofen and naproxen, they say.

How to make a profit from rotting garbage
Tue, 31 Mar 2015 10:08:59 EDT
Landfills can make a profit from all their rotting waste and a new patent explains exactly how to make the most out of the stinky garbage sites. Decomposing trash produces methane, a landfill gas that can be used to produce electricity or heat. Since methane is a greenhouse gas and most landfills don't produce enough of it to make energy production worthwhile, many dumpsites burn, or flare, the methane away so that the harmful gas does not escape into the atmosphere. But a new process shows how landfills can up their methane production to turn a profit.

An efficient path from carbon to renewable fuel production

Earth-abundant materials based primarily on carbon, nitrogen and transition metal oxides can be combined into highly efficient energy conversion devices. These devices can be used in fuel cells as well as in electrolysis.

New imaging tool targets degenerative diseases
Mon, 30 Mar 2015 16:24:12 EDT
Figuring out what's happening at a cellular and molecular level may help scientists develop ways to treat or prevent age-related, neurogenerative diseases, such as Alzheimer's and Parkinson's. Researchers have developed the first imaging reagent that can determine thiol levels in intact living cells. Now they are working on reagents that can selectively show thiol density in subcellular structures, specifically the nucleus and mitochondria, hoping to develop a nontoxic reagent safe enough to be used for diagnostic imaging, like an MRI.
