...ces, such as a laser in a CD player, the product's efficiency also becomes more optimized. "By engineering a structure at the nanoscale, you might be able to pump in energy, and immediately excite a dramatic optical response." If a chip can be made with components that guide light energy waves in a way similar ...Maine chemist wins national award for research and mentoring

With their attractive colors and important roles in nature, carotenoids can draw students to the basics of electron structure, energy transfer and other fundamentals of physical chemistry. In turn, Christensen can th...Dartmouth researchers put recycling in perspective
... steadily gone up, and during that same time, fuel efficiency has gone down, because Americans are choosing less fuel efficient vehicles. The authors argue that if the mix of cars and SUVs (which in this study includes sport utility vehicles, light trucks and minivans) had stayed at the 1989 level, it would hav...Atomic force microscope powerful new tool for measurement of particle attraction

...bstantial sink (CO2-absorbing site): its absorbing efficiency is similar to that of many of its counterparts in more fertile lands. These results were unexpected since forests in dry regions are considered to develop very slowly, if at all, and thus are not expected to soak up much carbon dioxide (the more rapi...Protein mimetics could lead to more successful coronary bypasses

This research is part of an overarching goal to create protein-based pharmaceuticals to treat a variety of diseases. The next step is to take a HSP20 mimetic into stage one clinical trials so that its efficacy and safety in human...... chick embryo cells, the researchers achieved this efficiency by tracing how two important gene and protein-regulated pathways of nerve generation collaborate to create specialized nerve cells, including motor neurons.
