The year 2018 is ending with spectacular success of Indian scientists and technologists in space and defence sectors, with a series of high impact missions. But that’s not all Indian scientists achieved in 2018. Several scientific developments, new techniques and promising technologies – in fields ranging from nanotechnology to space weather – made headlines during the year. Here is a collection of 15 such stories that gives a glimpse of important developments reported by Indian scientists during the year.
A gel that can protect farmers from toxic pesticides
Most farmers do not wear any protective gear while spraying chemicals in fields, which often leads to pesticide exposure and toxicity. Scientists at the Institute for Stem Cell Biology and Regenerative Medicine, Bangalore have developed a protective gel – poly-Oxime – that can be applied on skin and can break down toxic chemicals into safe substances, preventing them from going deep into the skin and organs like the brain and the lungs. The research group plans to develop a mask that can deactivate pesticides.

World’s thinnest material with novel technique
Pushing the envelope in nanotechnology, researchers at the Indian Institute of Technology Gandhinagar have developed a material that is 100,000 times thinner than a sheet of paper. They synthesized a two-dimensional material of just one-nanometer thickness (a human hair is about 80,000 nanometer wide) using Magnesium diboride – a compound of boron. This is said to be the world’s thinnest material. It can find a range of applications – from next-generation batteries to ultraviolet absorbing films.

Discoveries to tackle Zika, dengue, JE and chikungunya
The National Brain Research Centre (NBRC) at Manesar has figured out cellular and molecular mechanisms that show how Zika virus causes microcephaly or small head size in babies. Researchers discovered that envelop protein of zika virus affects proliferation rates of human neural stem cells and promotes premature but faulty neuron formation.
Another study led by scientist at the Regional Centre for Biotechnology, Faridabad has identified a key protein which helps dengue as well as Japanese Encephalitis viruses replication inside human body by inhibiting anti-viral cytokines. This finding could pave way for development of targeted drugs for dengue and JE. For detecting Chikungunya, a group of researchers from Amity University, Noida, Jamia Millia Islamia University, Delhi and Maharishi Dayanand University, Rohtak, have developed a biosensor using molybdenum disulphide nanosheets.
Faster diagnostic tests for tuberculosis
Scientists at the Translational Health Science and Technology Institute, Faridabad and All India Institute of Medical Sciences, New Delhi have jointly developed highly sensitive and rapid tests for detection of tuberculosis infection in lungs and surrounding membranes. Unlike current tests that use antibodies for detection of bacterial proteins in sputum samples, new tests use Aptamer Linked Immobilized Sorbent Assay (ALISA) and Electrochemical Sensor (ECS) for detection of a bacterial protein in the sputum.

Arsenic found in Punjab groundwater
Till now arsenic was a major problem in West Bengal, Bihar, Jharkhand, Uttar Pradesh, Assam, Manipur and Chhattisgarh. It was also known that there is arsenic contamination in groundwater in Punjab. Now a new study done by New Delhi-based TERI School of Advanced Studies has found that that Punjab’s floodplains are severely affected by arsenic contamination. In some wells, arsenic levels were found to be 20 to 50 times higher than WHO prescribed limit.

Space weather warning model rules out ‘mini ice age’
A team of scientists from the Indian Institute of Science Education and Research (IISER) Kolkata have dismissed the speculation that the upcoming sunspot cycle is going to be stronger, based on calculations using a model developed by them. The near-Earth and inter-planetary space environmental conditions and solar radiative forcing of climate over the upcoming sunspot cycle 25 will likely be similar or marginally more extreme relative to what has been observed during the past decade over the current solar cycle. The method makes it possible to make predictions almost a decade before the next sunspot cycle activity peaks in strength.

New tool developed for autism screening
In many cases, autism is misdiagnosed as mental retardation and attention deficit hyperactivity disorder. Early identification and interventions may help children with autistic disorders. To help this process, scientists at the Government Medical College and Hospital, Chandigarh, have developed an Indian tool for screening children for autism. The Chandigarh Autism Screening Instrument (CASI is designed to help community health workers to carry out initial screening for autism.

Hope for Alzheimer’s, Huntington’s
Scientists at the Indian Institute of Science (IISc), Bengaluru, have figured out the way memory deficit develops in early stages, resulting in Alzheimer’s disease. They have found that early breaking down of a protein, fibrillar actin or F-actin, in the brain leads to disruption in communication among nerve cells and consequently memory deficits. This knowledge can be used to develop early diagnosis test in future.

Green technique can address Plaster of Paris pollution
A team of scientists at Pune-based National Chemical Laboratory (CSIR-NCL) has developed a technique that helps recycle Plaster of Paris waste from hospitals in an eco-friendly and economical way. The new technique disinfects waste and converts it into useful products like ammonium sulphate and calcium bicarbonate. The technique can also be used to disintegrate PoP waste from idols immersed in water bodies.

Stone Age tools, genetic studies throw new light on peopling of India
The Stone Age tools discovered in a village near Chennai suggest that a Middle Palaeolithic culture was present in India around 385,000 years ago — roughly the same time that it is known to have developed in Africa and in Europe. The discovery pushes back the period when populations with a Middle Palaeolithic culture may have inhabited India, and challenges popular theory that the Middle Palaeolithic was brought to India by modern humans dispersing from Africa only around 125,000 years ago or later. In the North, a population genetic study has revealed that the Rors who inhabit modern Haryana came to the Indus Valley when it was flourishing during the Bronze Age and inducted West Eurasian genetic ancestry.
