‘Damaru’ Inspired Lattice

IIT Kanpur Researchers have developed ‘Damaru’ Inspired Lattice that finds applications in stealth submarines and high speed trains.

Sponsored by: A SPARC project of Ministry of Education.

With the use of a micro-structured hour-glass shaped meta-structure in the lattice unit, one can get a wider variation of propagation and stop bands.

Inspiration of the lattice has come from a two-headed drum called ‘Damaru’ or which is used in ancient Hinduism and Tibetan Buddhism. 

It is said that Lord Shiva has produced a special sound through this musical instrument to create and regulate the universe.

In this application, the researchers have also shown that the nature of stiffness of a vibrating medium could be altered drastically by controlling the lattice micro-structure from regular honeycomb to auxtetic honeycomb structure.

This has wide applications in the field of vibration isolation in high speed trains, stealth submarines and helicopter rotors.

Muni Bonds

Bonds issued by the Lucknow Municipal Corporation (LMC) were listed on the BSE, raising Rs 200 crore for Uttar Pradesh’s capital.

According to UP Chief Minister, Ghaziabad will be the next to issue a municipal issue and it will be followed by Pragyaraj, Varanasi, Agra and Kanpur.

Lucknow is the ninth city in the country to raise capital through municipal bonds.

Until now, a cumulative amount of Rs 3,600 crore has been raised via muni bonds in the country. 

The money raised using such bonds is typically used for infra projects such as roads, water and housing.

In 2015, market regulator SEBI had issued the framework for raising capital by way of muni bonds.

Among the key eligibility criteria for issuing these bonds is that the local body shouldn’t have negative net worth in any of the three preceding financial years and shouldn’t have defaulted on payments in the last one year.

Indian Peacock Softshell Turtle rescued

Indian peacock softshell turtle, a turtle of a vulnerable species was rescued from a fish market in Assam’s Silchar.

The Indian peacock softshell turtle [Nilssonia hurum] is a species of turtle found in South Asia.

IUCN Red list status: Vulnerable species.

Schedule I species in the Indian Wildlife Protection Act, 1972

This species is confined to India, Bangladesh and Pakistan.

In india, it is widespread in the northern and central parts of the Indian subcontinent.

These are found in rivers, streams, lakes and ponds with mud or sand bottoms.

Major Threats:

(1) Heavily exploited for its meat and calipee;

(2) Reduction of fish stock, due to overfishing, pollution, increase in river traffic, and sand-mining, among others.

According to a report by Guwahati-based conservation NGO, Help Earth, 29 species of turtles have been recorded in India, out of which 20 are found in Assam.

SCO Online International Exhibition launched

Recently, the Vice President of India has launched the first ever SCO Online Exhibition on Shared Buddhist Heritage.

influenza makes people more susceptible to bacterial infections.

Influenza makes people more susceptible to bacterial infections: Sweden’s Karolinska Institute

Recently, researchers at Sweden’s Karolinska Institute have come out with findings on superinfections.

They have highlighted that influenza makes people more susceptible to bacterial infections.

When an individual is infected by influenza different nutrients and antioxidants, such as vitamin C, leak from the blood.

The absence of nutrients and antioxidants creates a favourable environment for bacteria in the lungs.

The bacteria adapt to the inflammatory environment by increasing the production of an enzyme called High temperature requirement A (HtrA).

The presence of HtrA weakens the immune system and promotes bacterial growth in the influenza-infected airways.

The ability of pneumococcus to grow seems to depend on the nutrient-rich environment with its higher levels of antioxidants that occurs during a viral infection, as well as on the bacteria’s ability to adapt to the environment and protect itself from being eradicated by the immune system.

The results could be used to find new therapies for double infections between the influenza virus and pneumococcal bacteria.

The information can contribute to the research on Covid-19.


These are infection occurring after or on top of an earlier infection, especially following treatment with broad-spectrum antibiotics. 

It is an overgrowth of an opportunistic pathogen from the bacterial or yeast imbalance of systemic antibiotics.

For example, influenza is caused by a virus, but the most common cause of death in influenza patients is secondary pneumonia, which is caused by bacteria.


It is a viral infection that attacks the respiratory system i.e. nose, throat and lungs.

It is commonly called the flu.

Symptoms: Fever, chills, muscle aches, cough, congestion, runny nose, headaches and fatigue.

Flu is primarily treated with rest and fluid intake to allow the body to fight the infection 

Young children, older adults, pregnant women and people with chronic disease or weak immune systems are at high risk.


It is an infection that inflames the air sacs in one or both lungs. 

The air sacs may fill with fluid or pus.

Cause: Variety of organisms, including bacteria, viruses and fungi.

Symptoms: Cough with phlegm or pus, fever, chills and difficulty breathing.

The infection can be life-threatening to anyone, but particularly to infants, children and people over 65.
