• Scaling Concepts in Describing Continuous Phase Transitions

Phase transitions, like the boiling of water upon increasingtemperature, are a part of everyday experience and are yet,upon closer inspection, unusual phenomena, and reveal a hostof fascinating features. Comprehending key aspects of phasetransitions has lead to the uncovering of new ways of describingmatter composed of large numbers of interacting elements,which form a dominant way of analysis in contemporarystatistical mechanics and much else. An introductorydiscussion is presented here of the concepts of scaling, universalityand renormalization, which forms the foundation ofthe study of continuous phase transitions, such as the spontaneousmagnetization of ferromagnetic substances.

• The Search for Another Earth - Part II

In the first part, we discussed the various methods for thedetection of planets outside the solar system known as theexoplanets. In this part, we will describe various kinds ofexoplanets. The habitable planets discovered so far and thepresent status of our search for a habitable planet similar tothe Earth will also be discussed.

• Neutrino Oscillations: New Windows to the Particle World

The 2015 Nobel Prize in Physics was awarded to two physicists-Takaaki Kajita and Arthur B McDonald, whose teams discoveredthat neutrinos, which come in three flavours, changefrom one flavour to another. This discovery is a major milestonein particle physics as it gives a clear evidence of physicsbeyond the Standard Model. Neutrino oscillation is a quantum mechanicalphenomenon whereby a neutrino created witha specific lepton flavour (electron, muon, or tau) can later bemeasured to have a different flavour. Historical developmentof the field in chronological order of experiments is brieflydescribed in this article.

• DNA Repair Systems: Guardians of the Genome

The 2015 Nobel Prize in Chemistry was awarded jointly to Tomas Lindahl, Paul Modrich and Aziz Sancar to honour their accomplishments in the field of DNA repair. Ever since the discovery of DNA structure and their importance in the storage of genetic information, questions about their stability became pertinent. A molecule which is crucial for the development and propagation of an organism must be closely monitored so that the genetic information is not corrupted. Thanks to the pioneering research work of Lindahl, Sancar, Modrich and their colleagues, we now have an holistic awareness of how DNA damage occurs and how the damage is rectified in bacteria as well as in higher organisms including human beings. A comprehensive understanding of DNA repair has proven crucial in the fight against cancer and other debilitating diseases.

• Segregation of Granular Material in Two and Three-Dimensional Units

Segregation of particulate materials in mixtures is controlledby differences in density, shape, and size. Experiments on segregationwere performed in two and three-dimensional demonstrationunits. The results conclusively indicated that the segregationof solids is affected by the shape, size and density ofgranular particles.
