<p>Researchers Pinpoint Neural Nanoblockers in Carbon Nanotubes</p>

<p>A team of Brown University scientists has pinpointed why carbon nanotubes tend to block a critical signaling pathway in neurons. It’s not the tubes, the team finds, but the metal catalysts used to form the tubes. The discovery means carbon nanotubes without metal catalysts may be useful in treating human neurological disorders. Results appear in <em>Biomaterials</em>.</p>

<p>Carbon Nanoparticles Toxic to Adult Fruit Flies But Benign to Young</p>

<p>Researchers at Brown University have discovered that certain types of carbon nanoparticles can be environmentally toxic to adult fruit flies, although they were found to be benign when added to food for larvae. The findings, <a href="http://pubs.acs.org/stoken/presspac/presspac/full/10.1021/es901079z">published online</a> in <em>Environmental Science &amp; Technology</em>, may further reveal the environmental and health dangers of carbon nanoparticles.</p>
