Princeton University engineers have developed a new laser sensing technology that may allow soldiers to detect hidden bombs from a distance and researchers to better measure airborne environmental pollutants and greenhouse gasses. "We are able to send a laser pulse out and get another pulse back from the air itself," said Richard Miles, a professor of mechanical and aerospace engineering at Princeton, the research group leader and co-author on the paper. "The returning beam interacts with the molecules in the air and carries their finger prints"........

In recent years, developers have been investigating light-harvesting thin film solar panels made from nanotechnology - and promoting efficiency metrics to make the technology marketable. Now a Tel Aviv University researcher is providing new evidence to challenge recent "charge" measurements for increasing solar panel efficiency........

A study that relates global energy use to economic growth, reported in the recent issue of BioScience, finds strong correlations between these two measures both among countries and within countries over time. The research leads the study's authors to infer that energy use limits economic activity directly. They conclude that an "enormous" increase in energy supply will be mandatory to meet the demands of projected world population growth and lift the developing world out of poverty without jeopardizing standards of living in most developed countries........
