1. Water molecules in Antarctic fish "dance a more ordered" dance due to the presence of anti-freeze proteins in their body, said a news report. The technique used to study this is called "terahertz spectroscopy".
Spectroscopy is a method by which an object's properties are studied by the way it disperses light passed through it. This is just like passing sunlight through a prism. When light is passed through a prism, it breaks into its constituent colours. By studying the constituent colours, scientists can know more about an object's properties.
Terahertz spectroscopy uses frequencies in the range of 0.3 THz to 10 THz. This frequency is invisible to the naked eye and can penetrate matter. In this study, Terahertz spectroscopy was used to study the interaction of water molecules with the anti-freeze proteins.
2. "...Universe was formed because of laws of physics and not divine intervention, " said acclaimed scientist, Stephen Hawking. He has added that the Universe was created spontaneously and the M-Theory would offer the best explanation for the creation of Universe.
