Carder’s research team is using data from NASA’s space-based SeaWiFS (Sea-viewing Wide Field-of-view Sensor) and MODIS (Moderate Resolution Imaging Spectroradiometer) instruments to detect harmful algal blooms. The satellite images provide data on ocean color (based on light intensities) and chlorophyll content. Like terrestrial plants, phytoplankton use chlorophyll for photosynthesis. Reflected light intensity and chlorophyll content can help scientists detect algal blooms. http://earthobservatory.nasa.gov/Features/Redtide/
An artificial neural network out of DNA, creating a circuit of interacting molecules that can recall memories based on incomplete patterns, just as a brain can. http://www.eas.caltech.edu/news/371 The DNA and Natural Algorithms Group: Research Our group is interested in biomolecular computation: how systems of biomolecules, such as DNA and enzymes, can process information and carry out algorithms. While our theoretical studies are wide-ranging, our experimental efforts focus on coaxing DNA to perform algorithmic tricks. http://www.dna.caltech.edu/DNAresearch.html

With the theme “Knowledge that Works: From Theory to Practice,” the 2011 ASTC Annual Conference featured more than 100 sessions, which highlighted how science centers and museums are putting new ideas to practical use to serve their communities. The conference was hosted by the Maryland Science Center in Baltimore, October 15-18.

Mars500 is an international study into interplanetary spaceflights and was the first full duration simulation of a manned flight to Mars. The mission started on 3 June 2010 and ended on 4 November 2011. This is the entire story of this mission. https://storify.com/ESA/mars-500-520-days-on-the-web
