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.

Around 4 Guiness world record to be attempted during the 5th India International Science Festival: 

Around four Guinness World Records is to be attempted during the course of the 5th India International Science Festival (IISF) that has been scheduled to begin in Kolkata on 5 November 2019. 

1) A small personal model of advanced spectroscopes ban is made by anyone using a box made of cardboard that has a very narrow window used to channel light into the spectroscope. A piece of a Compact Disc is used to split the light by a process called diffraction. This attempt is dedicated to renowned scientists Meghnad Saha and C. V. Raman.

2) The largest electronics lesson and assembly of optical media communication units at a single location will be attempted with the participation of over 950 students on 6 November.

3) The record attempt for most people assembling Radio kits simultaneously will be attempted on 7 November 2019 with the participation of over 400 students. 

4) The largest human image of a human chromosome will be attempted to be formed on 8 November 2019 with the participation of over 400 students.


The first and second IISF were held in New Delhi. The third edition was held in Chennai, and the fourth IISF was held in Lucknow. It witnessed a widespread footfall from over 10 lakh people, including foreign delegates. It is organized jointly by Science & Technology -related Ministries and Departments of the Government of India and Vijnana Bharati (Vibha).

Indian Railways installed two Health ATMs at the Charbagh railway station: 

The Indian Railways (IR) has installed two Health ATMs at the Charbagh railway station in Lucknow, Uttar Pradesh. The kiosks will provide 16 health check-ups for Rs.50-100. It was installed and promoted by YOLO Health ATM. The move aims to achieve the objectives of the Fit India programme. Health ATMs are used by 50-60 persons daily.

Health ATMs:

Two types of check-ups can be done the Health ATMs.

1) A 6-minute type check-up that costs Rs.50 

2) A 9-minute type check-up that costs Rs.100

The report will be delivered instantly to the email or the smartphone of the user. The ATMs help commuters to check their health conditions at a low cost. The check-ups include the body mass index (BMI), blood pressure (BP), body fat, hemoglobin, metabolic age, muscle mass, weight, height, temperature, muscle mass, basal metabolic rating, visceral fat, oxygen saturation, pulse rate, blood glucose, bone mass. A medical attendant staffs the Health ATMs at the railways. 

YOLO is planning to install similar Health ATMs in Bareilly and Moradabad of Uttar Pradesh. The NorthEastern Railway has decided to extend the primary health check-up facility to other stations such as Gorakhpur, Gonda, Prayagraj, and Basti. 

What is Health ATM?

Health ATMs are private, walk-in medical kiosks with integrated medical devices for neurology, cardiology, pulmonary testing, gynecology, basic laboratory testing, and emergency facilities, and basic vitals.
