Aloe Vera Used to Remove Oil from Water

A team from IIT Guwahati has for the first time used a naturally occurring material, aloe vera gel, which inherently has superior oil repelling (oleophobic) property to separate oil from water. So far researchers have only been mimicking the structure of naturally existing materials such as fish scales to achieve super oleophobicity. While conventionally the topography and chemistry of materials had to optimised to make them repel oil extremely, the use of aloe vera gel-based coating modified with some molecules was sufficient to make the surface of substrates extremely oil repelling.

Constellations Named After Fictional Characters

NASA scientists have devised a new set of 21 modern gamma-ray constellations and named them after fictional characters such as the Hulk and Godzilla.

The constellations, constructed with sources visible through its gamma-ray telescope, were devised to celebrate the completion of 10 years of operations of the Fermi Gamma-ray Space Telescope.
