Scientists from the Jawaharlal Nehru Center for Advanced Scientific Research explore whether seasonal variation in abundance of food and water have any effects on the size of elephant groups. The researchers found that although group sizes were larger in the dry season compared to the wet season at the population level, that was not so at the clan level.

Conserving wildlife seems to be the biggest concern for most ecologists who think habitat destruction, coupled with climate change, can spell doom for many animals on earth. The first step to know how badly a particular species is affected is by counting them. As simple as it sounds, counting populations, especially in the wild, is a daunting task. In addition to the sheer physical strain, social structures of certain animals like the elephants could result in errors in such population estimations. Now, a new study has leveraged the power of computer simulations to accurately estimate wild populations at the comfort of your desk.
Organisms with single cell mostly reproduce asexually through cell division by splitting into two or more cells and yeasts are no exception. They divide by fission or budding, a process where new daughter cells ‘bud’ off after receiving half of the nucleus and some cytoplasm from the mother cell. A recent collaborative study by scientists at the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), the Indian Association for the Cultivation of Science (IACS), the Tata Memorial Centre, Advanced Centre for Treatment Research and Education in Cancer, Navi Mumbai and the Indian Institute of Technology – Bombay, has now thrown some insights into the mechanism of nuclear division in yeasts. The study, led by Prof. Kaustuv Sanyal from JNCASR and Prof. Raja Paul from IACS, has succeeded in generating a computational model that accurately predicts the nuclear division dynamics in two types of yeasts belonging to two phyla - Ascomycota and Basidiomycota.
The vivid and myriad colours of the natural world captivate our eyes and benefit life on earth. Learning how nature colours its palette advances our understanding of the world around us and hence scientists ubiquitously are trying to imitate designs inspired by nature, to fabricate better devices. Now, a collaborative study between researchers at the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), Bengaluru, and the Indian Institute of Science (IISc), Bengaluru, has proposed a novel technique to build better display devices that imitate naturally occurring colours.
