Read moreResearchers have long viewed molybdenum sulfide (MoS2) as a promising, much cheaper alternative to platinum. The drawback is that MoS2's catalytic performance is far worse than platinum's. To get around that problem, researchers have been trying to find ways to improve MoS2's catalytic performance. And now they may be on to something.

The photovoltaic cells now used to turn sunlight into electricity can only absorb and use a small fraction of that light, and that means a significant amount of solar energy goes untapped. A new technology represents a first step toward harnessing that lost energy.

New technology (the size of a USB memory stick) could revolutionize genomic sequencing of drug-resistant bacteria. Researchers proved the utility of the new device by successfully mapping multi-drug resistance genes in a Typhoid-causing strain of bacteria - which has recently emerged globally. They say that the technology could enable bacterial identification, diagnosis of infectious diseases and detection of drug-resistance at the point of clinical need.
