CORD BLOOD BANKING
Part of: GS Prelims and GS-III- S&T
Recently there has been growing concern regarding the aggressively promoted concept of cord blood banking.
Key Points
Over the past decade, stem cell banking has been aggressively marketed even as its use is still in experimental stages.
The stem cell banking companies get access to data of to-be parents and start approaching their prospective customers much before the delivery and offer competitive packages.

The cartilage developed in the lab has remained physically stable for up to six weeks.
While the cartilage found in the knee i
CRISPR-Cas9 - Gene Editing
Part of: GS-III- S&T (PT-MAINS-PERSONALITY TEST)
Background
A Chinese researcher recently claimed that he had altered the genes of a human embryo that eventually resulted in the birth of twin girls. The genes were claimed to be “edited” to ensure that they do not get infected with HIV, the virus that causes AIDS. If proven, it would be the first instance of human offspring having been produced with specific desired attributes, using newly

What is Gene Sequencing?
A genome is the DNA or sequence of genes in a cell. Most of the DNA is in the nucleus and intricately coiled into a structure called the chromosome.
Every human cell contains a pair of chromosomes, each of which has three billion base pairs or one of four molecules that pair in precise ways. The order of base pairs and varying lengths of these sequence
3-D Bio-Printing
Part of: GS-III- S&T (PT-MAINS-PERSONALITY TEST)
The development of 3D bio-printers has raised the prospects of making tissues and organs in a more affordable way and consistent way. Bangalore based start-up Next Big Innovation Lab has made human skin with its own 3D bio-printer using 3D bio-printing with a secret bio-ink.
History of bio-printing
Creation of human skin in a lab for commercial use dates back to 1993 when MatTek, a company founded by two chemical e
Gene editing, the good first and then the worries
Introduction
The Nobel Prize in Chemistry for 2020 has been awarded to two women scientists, Emmanuelle Charpentier and Jennifer A. Doudna for the development of a method for genome editing.
This involved programming a Cas9 protein to cut a piece of DNA at a specific site with the help of a small piece of RNA, thereby proving the ability of CRISPR-Cas9 to function as a gene-editing tool.

In India, since there is a long
The twisted trajectory of Bt cotton
Introduction:
Cotton has been woven and used in India for thousands of years.
Cotton fabric from around 3,000 BCE has been excavated from the ruins of Mohenjo-daro, and archaeological findings in Mehrgarh, Pakistan, show that cotton was used in the subcontinent as far back as 5,000 BCE.
Indian cotton fabrics dominated the world trade during the succeeding millennia and were exported to many places, including Greece, Rome, Persia, Egypt, Assyria an
What are Micro Biomes?
Microbiome refers to microorganisms living inside humans and animals.
Eating too much fat and sugar as a child can alter one’s microbiome forever.
The balance of useful and harmful components, if disturbed, results in ill health.
Magnetic fields in plants
A recent study from Germany found that the Venus flytrap (a carnivore) plant is capable of generating small magnetic fields.
When the plant sends electrical signals to trigger the closure of its traps, a biomagnetism phenomenon was observed.
The trap gets electrically excited due to touch, osmotic energy & even heat and cold.
New Variety of Marigold Developed by IIHR
Indian Institute of Horticultural Research has developed a new variety of Marigold named Arka Shubha
This variety of marigolds can be used for the extraction of crude carotene up to 2.8%.
Presently, India imports most of its carotene from China
The Arka Shubha variety is of use in the poultry sector as well. Its petals could be used as feed to get quality yolk.
Coal Gasification
What is coal gasification?
• Coal gasification is the process of producing syngas [a mixture consisting primarily of methane (CH4), carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2) and water vapour (H2O)], from coal, water, air and/or oxygen.
What are its usages?
• Currently, this tech is primarily used for electricity generation, for the production of chemical feedstocks, or for the production of synthetic natural gas.
• The hydroge
Magnetic hyperthermia-mediated cancer therapy (MHCT)
It is a non-invasive cancer treatment.
The technique: Delivery and localisation of magnetic materials within the targeted tumour site followed by subsequent application of an alternating magnetic field (AMF), thereby generating heat at the tumour site.
It can efficiently act against deep-seated inaccessible solid tumours like glioblastoma (an aggressive type of cancer that can occur in the brain or spinal cord)
Abscisic Acid (ABA)
What is Abscisic Acid?
Glands are organs that secrete hormones at different times to stimulate body processes such as growth, development, and the breaking down of sugars.
Abscisic acid is a plant hormone involved in many developmental plant processes, such as dormancy and environmental stress response.
The function of Abscisic Acid
Plants have openings on the bottom side of their leaves, known as stomata.
Stomata take in carbon dioxide
Feluda Test
Feluda is the acronym for FNCAS9 Editor Linked Uniform Detection Assay.
It is an accurate and low-cost paper-based test strip to detect Covid-19 and can deliver a result in 45 minutes.
Developed by the Council of Scientific and Industrial Research (CSIR) and Tata Group.
How does it work?
It uses indigenously developed CRISPR gene-editing technology to identify and target the genetic material of SARS-CoV2, the virus that causes Covid-19.

Preterm delivery is a leading cause of Neonatal fatalities (deaths among live newborns within the first 28 completed days of life) and problems worldwide. Recently, Indian researchers working on the Garbh-Ini program have discovered 19 genetic markers linked to preterm birth.
An improvement in maternal and neonatal outcomes could result from the identification of genetic markers linked to preterm delivery and from the prediction and close monitoring of high-risk pregnancies.
