Researchers from the Mahatma Gandhi University, Kottayam, report that the diversity of earthworms enriches the carbon content of the soil.

In a recent study, researchers from Christ (Deemed to be University), Bengaluru, have developed a technique to make fluorescent carbon nanoparticles using lignite, a type of coal that is available ubiquitously. These nanoparticles have the potential to be developed as glucose sensors to detect hypoglycemia or decreased glucose levels.The results of the study have been published in the journal Scientific Reports.
