A team of University of California, San Diego researchers has built the smallest room-temperature nanolaser to date, as well as an even more startling device: a highly efficient, "thresholdless" laser that funnels all its photons into lasing, without any waste.

Individual cells modified to act as sensors using fluorescence are already useful tools in biochemistry, but now they can add good timing to their resumé, thanks in part to expertise from the National Institute of Standards and Technology (NIST).
With the added capability to track the timing of dynamic biochemical reactions, cell sensors become more useful for many studies, such as measurements of protein folding or neural activity.

The European Commission's Joint Research Centre (JRC) has published today a study mapping the potential of renewable energy sources in Africa. The report analyses the current energy consumption in Africa and assesses potential of renewable energy sources - solar, wind, biomass and hydropower - and their cost efficiency and environmental sustainability. Its publication coincides with the official European Launch of UN's Year on "Sustainable Energy for All" being held today in Brussels.

COLUMBUS, Ohio – When low-income cohabiting couples with children decide to no longer live together, that doesn't necessarily mean the end of their romantic relationship.
A new study suggests that about one in four of these couples who split their households still maintain some type of romantic relationship.

For swimmers looking to gain an edge on the competition, the notion that simply donning a different swimsuit – like a Speedo Fastskin II suit, with a surface purportedly designed to mimic by shark skin – can be the difference between first and last place is a powerful one.
It's also one that's almost completely misplaced, said George Lauder, the Henry Bryant Bigelow Professor of Ichthyology.

Risks related to the critical nature of arsenic — used to make high-speed computer chips that contain gallium arsenide — outstrip those of other substances in a group of critical materials needed to sustain modern technology, a new study has found. Scientists evaluated the relative criticality of arsenic and five related metals in a report in the ACS' journal Environmental Science & Technology.

Wind conditions at a fire scene can make a critical difference on the behavior of the blaze and the safety of firefighters, even indoors, according to a new report by the National Institute of Standards and Technology (NIST). The findings confirm earlier NIST research, but they take on a particular immediacy because they are based on detailed computer models of a tragic 2009 residential fire in Houston, Texas, that claimed the lives of two firefighters.
