The Fermi Gamma-ray Space Telescope from NASA recently discovered a signal from the center of the out neighbour galaxy Andromeda galaxy. This symbolizes the presence of a very mysterious material called dark matter. The gamma-ray signal is quite similar to that seen by Fermi at the center of our personal Milky Way galaxy. Gamma-rays happen to be the highest energy light form that is generated by most energetic phenomena in this universe. These are more common in galaxies such as the Milky Way as the cosmic rays particles move pretty close to the speed of light and generate gamma rays as these interact with starlight and interstellar gas clouds.
A team of engineers was recently successful in creation of a more thermally conductive and stretchable rubber that will pave a new path towards better development of flexible electronics and their inclusion in our regular lives. Thubber, as they like to call it, can be defined as a soft natured material that has microdroplets of liquid metal embedded in deformable silicon elastomer. The composite nature of this material permits thubber to attain its dual-nature properties of metal-like thermal conductivity and high elasticity. The liquid metal is quite capable of changing its shape with the rubber around it in order to maintain pathways for dispersion heat.
DNA, the fundamental cell of life, may give a good shock to all those engineers who have been trying hard to come up with lower-cost, more advanced electronic devices. The biggest development has just been made as a team of researchers was recently successful in developing a controllable DNA switch that is one thousand times smaller than one strand of human hair. So, now administration of DNA should be more like switching light on and off in home. These DNA switches will be able to regulate the electricity flow inside a single atomic-sized molecule. This study was made by a researcher name Nongjian Tao who worked at the Arizona State University Biodesign Institute.
