Read moreThe National Cancer Institute recently announced two five-year awards totaling nearly $4 million for a partnership between the University of New Mexico Cancer Center and Sandia National Laboratories. One $1.95 million grant will fund the creation of a joint Cancer Nanotechnology Platform Partnership, and another $1.8 million grant will pay for a new Cancer Nanotechnology Training Center to train a new generation of multidisciplinary scientists.

Read moreThe heat radiating off roadways has long been a factor in explaining why city temperatures are often considerably warmer than nearby suburban or rural areas. Now a team of engineering researchers from the University of Rhode Island is examining methods of harvesting that solar energy to melt ice, power streetlights, illuminate signs, heat buildings and potentially use it for many other purposes.

Read moreInformation coded as impulses is transferred from one neuron to its target at synapses. At these close neuron-neuron contacts the impulse opens voltage sensitive calcium channels allowing the influx of calcium ions (Ca2+) and this ion then acts as a 'second messenger' to trigger the release of neurotransmitters by the fusion of a secretory vesicle with the surface membrane. Scientists have now established that the relationship between the calcium channel and the secretory vesicle is very intimate, so much so that the fusion of a secretory vesicle can be triggered by the plume of Ca2+ entering through a very closely situated single calcium channel.
