<p>Single nanomaterial yields many laser colors</p>

<p>Engineers at Brown University and QD Vision Inc. have created nanoscale single crystals that can produce the red, green, or blue laser light needed in digital displays. The size determines color, but all the pyramid-shaped quantum dots are made the same way of the same elements. In experiments, light amplification required much less power than previous attempts at the technology. The team’s prototypes are the first lasers of their kind.</p>

<p>Did bone ease acid for early land crawlers?</p>

<p>In a new paper in the <em>Proceedings of the Royal Society B</em>, scientists propose that the bony structures in the skin of many early four-legged creatures might have been there to relieve acid buildup in bodily fluids. Analysis of their anatomy suggests that as they ventured out of water, the animals would have had trouble getting rid of enough CO<sub>2</sub> to prevent acid buildup.</p>

But two significant political movements began to break down those barriers in the last 60 years, bringing women into the musical fold. It is that shift — and its political, social, and cultural implications — that Julie Hunter studied to earn her Ph.D. this spring.</p>
