The article outlines the life and work of Maryam Mirzakhani
– the first and the only female winner of the Fields Medalsince its inception in 1936. Mirzakhani is an inspiration toyoung women around the world, to believe in their own abilitiesand pursue their academic dreams.

Colloidal dispersions are suspensions of micron-sized solidparticles in a solvent like water or oil. Self-assembly is awidely used approach to create ordered structures of colloidalparticles by engineering the inter-colloid potential. This articleillustrates how entropy drives disorder to order transitionsin a colloidal assembly.

Supramolecular chemistry as defined by Lehn ‘chemistry beyondthe molecule’ focuses on the development of functionalcomplex architectures through non-covalent interactions. Theyear 2017, marked the fiftieth anniversary of the serendipitousdiscovery of crown ethers. Since then, the field is growing,and due to the efforts of various researchers now it is possibleto have some control over the arrangement of things on asmall scale. In this review article, the concept of supramolecularchemistry, cooperativity responsible for interactions, techniquesfor determination of thermodynamic parameters ofcooperativity, and the contribution of supramolecular chemistryto nanotechnology is described.

Deoxyribonucleic acid (DNA) is the molecule that carries geneticinformation in a cell. The field of DNA nanotechnologyaims to use DNA as the basis for making complex nanometerscalestructures. While much progress has been made in creatingsuch nano-architectures, the use of these structureswithin organisms had never been attempted. Our work is focusedon using a simple DNA-based pH sensor in worms toyield information about organelle activity in cells. The firstof its kind, this work set up a system to use DNA as a probein living systems.

Permeating across societies and cultures, music is a companionto millions across the globe. Despite being an abstractart form, music affects all of us deeply, encouraging us in periodsof difficulty, comforting us in moments of sadness andcelebrating with us in times of joy. In recent years, neuroscientistshave recognized that listening to and producing musicinvolves a tantalizing mix of practically every human cognitivefunction. Thus, music has emerged as an invaluable toolto study varying aspects of the human brain such as auditoryand motor perception and learning, attention, memory, andemotion. In this paper, we will discuss the different attributesof music and the neural structures associated with them. Wewill also highlight some recent work in our laboratory at theNational Brain Research Centre in India on emotions associatedwith Hindustani r¯aga music.

Molecular techniques are gaining importance in biodiversityconservation in India. They are especially beneficial in thecase of rare species with cryptic habits that make them difficultstudy subjects when using conventional field techniques.Molecular tools can be used to decipher distributions andpopulation connectedness in fragmented habitats and identifypopulations of immediate conservation concern. We discussthese with case studies on some cat species in India.

Invasive alien species are a growing conservation problem,worldwide. There are over 200 invasive plants in India, ofwhich Lantana camara is one of the best known. This articlelooks at a brief history of Lantana’s arrival and spread acrossthe Indian subcontinent and the lessons that conservation biologistscan learn from it.

Earthquakes occur as the natural outcome of the processesthat govern a dynamic planet, one that supports plate motions.The internal structure of the Earth that can sustain theconvective flow of the mantle and the presence of a strong,fractured outer shell, the lithosphere that can glide over theunderlying asthenosphere are important components of theplate tectonic framework, and therefore, the global distributionof earthquakes. With an introduction to the ideas of platetectonics and earthquake terminology, this article introducesthe significance of the India-Eurasia plate boundary and itsseismic productivity. The most active continent-continent collisionboundary on the Earth defined by the Himalaya andthe Andaman-Sumatra subduction zone are part of this plateboundary. Parts of the Indian continental interior regions arealso noted for some destructive earthquakes. This article providesa brief overview of the background processes, terminology,and some highlights on Indian earthquakes studies, andpoints to academic opportunities in the area of earthquakestudies.

Using Sun’s energy effectively to drive important, industriallyrelevant chemical reactions is currently an area of researchthat is attracting a large attention. This route circumventsour reliance on non-renewable sources of energy and moreimportantly prevents the release of hazardous pollutants as abyproduct. One such reaction that has a large industrial relevanceis the splitting of water to release hydrogen and oxygen.This is a thermodynamically energy intensive reaction, andthe most relevant aspect is that hydrogen gas is the productwhich is being touted as a fuel of the future. Its energy densityvalue is higher than other commercially relevant fuels,and its combustion only produces water as a byproduct withzero carbon footprint. Presented here are the current routesbeing considered for effective water splitting and the fundamentalprinciples that need to be considered when pursuingnew directions in this area.
