Nature is an enigma; an ensemble of complex structures and functions come together to form a variety of mesmerising artefacts, including life. Richard Feynman, the well-known American Nobel Laureate and physicist, famously said—"Nature isn't classical, dammit, and if you want to make a simulation of nature, you'd better make it quantum mechanical, and by golly it's a wonderful problem, because it doesn't look so easy".

Today is National Science Day—a day to celebrate the spirit of science and scientific temper across the county. It is a day to commemorate Sir C V Raman’s discovery of the Raman effect. This year, the theme of National Science Day is ‘Women in Science’, celebrating the contributions of women scientists to the field of science in India.

Starting in 2006, North Korea has made a series of nuclear tests in its hidden backyard. The country’s latest one was conducted in 2017 at Punggye-ri, some 3.6 kilometres northwest of its first nuclear test site. Despite its success, the test results provided loose estimates of the source parameters like the energy produced and the depth of the explosion. Since this was the most extensive test conducted by North Korea, it has evoked special attention among the scientific community in the last two years. While many studies have tried to reckon these parameters, the results were shrouded in uncertainty. Besides, the country’s political abnegation of seismometers called for an exigent need for a more accurate means of estimating the blast site’s characteristics. In a recent study, published in the Geophysical International Journal, a team of scientists from the Indian Space Research Organisation (ISRO) seems to have done just that.

Researchers find a unique new technique to make stable, low-power graphene transistors

Researchers at IIT Bombay develop the country’s first indigenously designed and fabricated microprocessor. 

Prof Subimal Ghosh, Professor at the Department of Civil Engineering, Indian Institute of Technology Bombay (IIT Bombay), has been awarded the Shanti Swarup Bhatnagar Prize 2019 by the Council of Scientific and Industrial Research (CSIR). This award recognises his significant contributions to our understanding of how land surface processes influence the Indian monsoon, as well as for improving regional monsoon simulations and predictions. 

As Newton’s famous quote, “standing on the shoulders of giants”, this year, science has made considerable advances, building on many feats achieved in the past years. New discoveries, insights and inventions in the areas of astronomy, biology, medicine, paleontology and physics marked the year. Here is a selected pick of ten such breakthroughs in science witnessed in 2019.

While looking forward to 2020, the editorial team at Research Matters looks back on some of the interesting stories that we published during 2019. There were many interesting ones ranging from the first photograph of a black hole to air pollution in Delhi to using vibrations for painless injections. Here is a list to highlight India's year in science during 2019. This is in no way ranked and the order is just incidental.

2019 was an exciting year for science as ever. We have collated the top ten stories that was popular on Research Matters in 2019. These were the ones that garnered most views because of readers like you. We would like to thank you for patronage and look forward to your support in the years to come.

Graphene, a sheet-like form of carbon, has been hailed as a wonder material owing to its many promising applications in electronics, drug delivery and more. In a recent study, a team of scientists from India and the USA, led by Prof Srinivasan Raghavan and Prof Rudra Pratap from the Indian Institute of Science (IISc), Bengaluru, has paved the way for new applications of graphene by intentionally varying the defects formed during its production.
