Haven’t we all heard about DNA, the genetic material that makes who we are? Short for Deoxyribonucleic acid, the DNA is made of two chains that coil around each other forming the double helix structure as we know it today. Although Friedrich Miescher first isolated the DNA molecule in 1869, it was not until 1953 that we understood its structure. Two scientists, James Watson and Francis Crick, are well-known for showing us the double-helix structure of the DNA.

Researchers from Indian Institute of Science Education and Research (IISER) Thiruvananthapuram, Kerala and Institute of Microbial Technology, Chandigarh have developed a novel method to synthesize 2 dimensional nanosheets decorated with DNA molecule. The design strategy allows for an ultra dense array of DNA molecules to be grown on 2 D crystalline nanosheets.
Scientists from Council of Scientific and Industrial Research – Indian Institute of Toxicology Research (CSIR-IITR) and Amity University, Uttar Pradesh have been studying the harmful effects of Zinc Oxide nanoparticles (ZnO NPs) on living tissue and genes in mice, and their study reveals a potential threat lurking, if increasing use of such nanoparticles is not addressed soon.
Dr. Lalji Singh was born in the small village of Kalwari in Jaunpur district of Uttar Pradesh on 5th July 1947, to a farmer and head of village, Suryanarayan Singh. With no higher education facilities in his village, Lalji strived for an education early on, travelling to a nearby village to complete his schooling and joining the reputed Banaras Hindu University.

Chillies are an indispensable part of the Indian platter and contribute heavily to our economy since India is a leading producer of chillies. A threat facing the chilli farmers is the fungal disease caused by Colletotrichum truncatum that affects the yield of the crop. In a new study, scientists have explored the mechanism behind the fungal disease, how the fungus actually attacks the plant and fruits and have also studied the genotype of the causative agents. This study, the researchers believe, can help develop mitigation plans and save farmers from an impending crop loss.
