Chandrayaan 2 found Argon 40 in lunar space:

The Indian Space Agency, Indian Space Research Organisation (ISRO), reported that Chandra`s Atmospheric Composition Explorer-2 (CHACE-2) payload on Chandrayaan-2 detected Argon-40 (40Ar) from the lunar exosphere. Among the radiogenic gases present on the surface of the Moon, 40Ar is one of the isotopes of Argon, which is a noble gas. The detection of 40Ar in the lunar exosphere is significant for ISRO as it has a high escape rate.

Argon in Moon:

Argon is an important component of the exosphere of Moon. It originates from the radioactive disintegration of Potassium-40 (40K). 40k has a half-life of 1.2X109 years. 

40K nuclide is present deep below the lunar surface. It gets disintegrated to 40Ar, which makes way up to the lunar exosphere through seepages and faults. 40Ar escapes from Moon at a high rate between 3% and 6%.

IIT Hyderabad developed the worlds firstever Indian Brain Atlas:

Researchers at IIT Hyderabad developed the world`s first-ever Indian Brain Atlas. It defines a template for the brains of people living in the Indian subcontinent. The study revealed that the Indian brain is smaller in size, width, and volume when compared to the brain from the Western and Eastern populations. 

Indian brains differ from MNI`s template:

Indian brains are smaller in size as compared to the Montreal Neurological Institute and Hospital (MNI) template. The difference in the size of the brain in scans look alarming and lead to misdiagnosis. The study is desirable in order to build a larger atlas as it is important to understand structurally what is normal. This would help to find several brain conditions in the early stage.

The team under Jayanthi Sivaswamy created India-specific templates by taking data from 50 individuals that are balanced perfectly between males and females. The MRI scans of the brains of the subjects were taken at 3 different hospitals in three different scanners to nullify variations in the scanning machines.
