Exoplanet discovery Google Doodle

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

Cell-infused Gloves and Bandages light up when in contact with certain Chemicals

Engineers and biologists at MIT have teamed up to design a new “living material” — a tough, stretchy, biocompatible sheet of hydrogel injected with live cells that are genetically programmed to light up in the presence of certain chemicals. In a paper published this week in the Proceedings of the National Academy of Sciences, the … Continue reading “Cell-infused Gloves and Bandages light up when in contact with certain Chemicals”

MIT’s new model could help scientists design materials for artificial photosynthesis

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”

Porous, 3-D forms of Graphene developed at MIT can be 10 times as strong as steel but much lighter

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”
