UC Berkeley current oceanographer, Francis Smith, explains about rip currents, how to avoid them, and how to escape them if pulled in.
The Search Engine Google is showing an Animated Doodle for celebrating the Discovery of the Seven Earth-size Exoplanets. NASA’s Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in the habitable zone This exoplanet system is called TRAPPIST-1
Plants and other photosynthetic organisms use a wide variety of pigments to absorb different wavelengths of light. MIT researchers have now developed a theoretical model to predict the spectrum of light absorbed by aggregates of these pigments, based on their structure. The new model could help guide scientists in designing new types of solar cells … Continue reading “MIT’s new model could help scientists design materials for artificial photosynthesis”
A team of researchers at MIT has designed one of the strongest lightweight materials known, by compressing and fusing flakes of graphene, a two-dimensional form of carbon. The new material, a sponge-like configuration with a density of just 5 percent, can have a strength 10 times that of steel. In its two-dimensional form, graphene is … Continue reading “Porous, 3-D forms of Graphene developed at MIT can be 10 times as strong as steel but much lighter”
The Australian National University (ANU) has led an international project to make a diamond that’s predicted to be harder than a jeweller’s diamond and useful for cutting through ultra-solid materials on mining sites. ANU Associate Professor Jodie Bradby said her team – including ANU PhD student Thomas Shiell and experts from RMIT, the University of … Continue reading “New Diamond Harder than Ring Bling”
