• Indian Scientists have recently found that the cancer-causing virus Epstein-Barr Virus (EBV) affects the glial cells or the non-neural cells in the central nervous system and alters molecules like phospho-inositols (PIP); a type of lipid, glycerol, and cholesterol, when the virus infects the brain cells. This could pave the path towards understanding the probable role of the virus in neurodegenerative pathologies, especially given the fact that the virus has been detected in brain tissue of the patients suffering from neurological disorders such as Alzheimer's, Parkinson and multiple Sclerosis.

• The amount of carbon in Earth's atmosphere in May 2021 reached its highest level in modern history, a global indicator – Keeling Curve - showed.

• It is a graph that represents the concentration of carbon dioxide (CO2) in Earth’s atmosphere since 1958 at the Mauna Loa Observatory in Hawaii.

• Scientists from the University of Hyderabad have found frequent formation of sub-3 nanometres aerosol particles in the atmosphere. The formation of small molecular clusters of sub-3nm size is technically called aerosol nucleation.

• Every year, the Indian Coast Guard’s “Operation Olivia”, initiated in the early 1980s, helps protect Olive Ridley turtles as they congregate along the Odisha coast for breeding and nesting from November to December.
