📰 Strings attached {Art & Culture}

Context

This article discusses about the regional practice of depicting the tale of Ramayana in a temple.

Aryankavu temple

  • It is an ancient temple in Shoranur provides a perfect backdrop for Tholpavakoothu, a 2,000-year-old puppet art form practised in Thrissur, Palakkad and Malappuram districts of Kerala.
  • The temple owned by a family is, perhaps, the only venue where all episodes (Kandams ) of the Kamba Ramayana are staged.
  • Nearly 200 puppets for the 21-day show is used, each representing a character in sitting, standing, walking or fighting posture.

Story behind it

Legend has it that as Bhagavathy, or the Mother Goddess, was fighting the demon Darika, she could not watch the Rama-Ravana war.

So the Ramayana is staged for her. In most temples, the idol of the goddess is placed on a pedestal and Tholpavakoothu is staged in front of the deity.

The Koothu is performed on a stage called Koothumadam, and many temples have such permanent structures.


📰  Navy steps up patrolling of Indian Ocean Region {Defence}

In news

The Indian Navy is broadening its patrol areas in the Indian Ocean Region to cover all choke points in the face of increasing maritime threats.

Highlights

The ingress and egress routes of the Indian Ocean Region are being kept under surveillance so that we have better awareness and know what is happening .

Under the mission-based deployment, 12 to 15 ships are now permanently deployed at the choke points and crucial sea lanes of communication.

Reference to China

The Chinese have been sending ships to the northern Indian Ocean in the name of anti-piracy operations and over the last two to three years on average about 8-10 ships have been deployed. This August, the number shot up to 14.

Apart from getting access to several ports and facilities in the Indian Ocean, China recently opened its first overseas military base in Djibouti in the Horn of Africa, giving it the ability to monitor across the Gulf of Aden and the Persian Gulf.

Key takeaway

Identification of common security threats across all countries and a broader agreement for greater coordination and information sharing. The threats, essentially non-traditional in nature, include maritime terrorism, unregulated fishing, illegal fishing in the global commons, pollution, sea piracy, drug and human trafficking.


📰 U.S. discusses Maldives turmoil with India {Internation}

A team of U.S. diplomats met senior External Affairs Ministry officials of India to discuss the events in the Maldives on Thursday.

US and India are working together to counter expanding Chinese influence.

Areas of concern

Maldives was the crackdown by the government on Opposition leaders, most of whom are in exile facing prison terms as former President Mohammad Nasheed or are under arrest as former President Maumoon Abdul Gayoom’s son Faris Maumoon.

The growth of Islamist radicalism was another area of concern discussed, given the fall of IS would send foreign fighters back to their countries of origin.

The U.S. diplomats also brought up the growing influence of Chinese investment, as well as its maritime presence, with the China-Maldives “friendship bridge” from Male to Hulhumale, an island being developed by Chinese companies, becoming the focus of their attention.


📰 ‘Climate change due to humans’  {Climate Change}

In news

The United States government on Friday released a major scientific report that says climate change is “extremely likely” to be caused by human activity and will get worse without major cuts to carbon emissions.

Report

global annually averaged surface air temperature has increased by about 1.8 Fahrenheit (1 degree Celsius) over the last 115 years (1901-2016).

“This period is now the warmest in the history of modern civilization,” said the report, available at science 2017

How humans are cause of climatic change

Direct evidence of human contribution to atmospheric CO2.

heat-trapping emissions from burning coal, gas and oil in power plants and cars; cutting down and burning forests; tiny pollution particles (aerosols); black carbon pollution more commonly referred to as soot; and changes in land use that also affects Earth’s albedo.

Fossil fuel burning by humans emits tiny particles in addition to releasing CO2 in the atmosphere. Some particles reflect sunlight back to space (aerosols), similar to the volcanic particles, having a cooling effect.


📰 IIT Guwahati uses superhydrophobic cotton to remove oil-spill {Sci & Tech}

In news

A team of researchers led by Dr. Uttam Manna from the Department of Chemistry at the Indian Institute of Technology (IIT) Guwahati have developed medical cotton than can absorb oil and repel water.

The researchers turned the medical cotton, which is extremely water absorbing, into a superhydrophobic (water contact angle of 157 degrees) material and used it for absorbing oil both in air and under water.

Characteristics of this cotton

The efficiency of absorption is very high — above 2,000 weight percentage for both heavy and light oils. This translates to one gram of the superhydrophobic cotton absorbing 20 grams of either heavy or light oils.

The absorbed oil can be recovered through physical compression. The superhydrophobicity remained intact even when the cotton was manually compressed up to 1,000 times and subjected to other physical manipulations.

The other important characteristic is its ability to absorb oil from three complex phases

light oil that floats in the air

water interface, sediment oil that settles at the bottom as it is heavy,

from water-in-oil emulsion

Limitations

cotton is able to efficiently absorb oil from water-in-oil emulsion, it is inherently incapable of removing oil from oil-in-water emulsion.

In the case of oil-in-water emulsion there is very little of oil present. “Since there is more water present, the superhydrophobic material does not come in contact with oil and so will be unable to remove oil efficiently from oil-in-water emulsion


📰 Hotspots of rattan found in Western Ghats {Bio-diversity}

In news

Scientists have discovered that non-protected areas near the Agastyamalai Biosphere Reserve, Silent Valley-Mukurthi National Parks and Coorg-Wayanad in the Western Ghats are hotspots of rattan or cane (light, flexible climbing palms) species.

Urgent conservation attention in the face of threats including habitat loss and excessive harvesting would be critical here.

What is rattan?

Rattans are spiny climbing palms used in making cane furniture and mats, an industry that is growing at US$4 billion trade per year.

Genomics were useful in phylogeny reconstruction of Calamodeae, and the molecular taxonomy of Calamus and related genera is an important research focus. Rattans are harvested from forests that require conservation efforts.


📰 Small molecule reverses antibiotic resistance {Science & Tech}

In news

Using a small molecule screened from a synthetic library of 8,000 molecules, researchers at the Indian Institute of Technology (IIT) Roorkee have been able to reverse drug resistance and restore the efficacy of fluoroquinolone-group of antibiotics by inhibiting the proton gradient which drives the efflux pump.

Report of the study

  • The team studied the efficiency of the small molecule in multidrug-resistant bacteria Acinetobacter baumannii.
  • While the small molecule did not inhibit the growth of the bacteria per se, it was able to enhance the activity of a few antibiotics such as ciprofloxacin and norfloxacin in fluoroquinolone-resistant clinical isolates of A.
  • The use of small molecule inhibitor not only restores the efficacy of antibiotics but also decreases the frequency of resistant bacteria

Why the study was done?

They found that lower dosage of antibiotics were sufficient to kill the bacteria when used along with the small molecule.


📰 Phone App for cancer study  {Science and Technology}

In news

A new smartphone App, SmartIHC-Analyser, developed by researchers at the Indian Institute of Technology (IIT) Kharagpur can now help in faster and more accurate evaluation of cancer after treatment.

Highlights

The App analyses the expression of a protein marker (Ki-67) for determining an increase in cancer cells. The App, now available for Android phones, analyses microscopic images of stained cancer tissue and in less than a minute tells if there is progression or regression of cancer cells post treatment.

The smart phone is fitted to the eye-piece of the microscope using a specially designed 3D-printed holder to take microscopic images of the cancer cells.

Traditional method of cancer study

In the manual method, pathologists observe these colours using the naked eye and count the cells. This method is time-consuming and technician-dependent. The new App takes pictures and counts the differently stained cells and gives the proliferation index in less than a minute.

“The proliferation index tells us the rate at which the cells are dividing or how fast the tumour is growing during the progress of cancer and helps in deciding future therapy. In manual counting, pathologists observe only two to four different areas of the tissue and give a mean score.
