Seshadri Dutta, NIIT University Introduction Recently, there has been a major interest in using laser therapy in health and dentistry. There are various types of lasers available, and their applications are well defined by parameters such as wavelength, energy density, power output, and radiation duration. For example, light interacts with photosensitive cells in our retinas […]
Aqsa, Jamia Millia Islamia A nucleosome is a DNA segment of 147-bp coiled around a histone octamer. Each histone octamer is made up of two copies of each of the histone proteins H2A, H2B, H3, and H4. It is the fundamental subunit of chromatin. Although it seems that the nucleosome has its significance only in […]
Anannya Roy, Amity University Kolkata Two new species of Mammal-like burrowing animals have been discovered in Northeastern China. These animals lived around 120 million years ago, and though both are distantly related, they have independently evolved the traits for digging. Paleontologists call them the first “Scratch-diggers” of the ecosystem. Organisms live underground for a variety […]
Ayooshi Mitra, Amity University Kolkata In Chilean Patagonia, a fossil sample of a skunk-like animal from the dinosaur time has been identified, adding to current evidence that mammals roamed that part of South America much earlier than previously thought. Close to the famous Torres del Paine national park, a portion of the creature’s fossilized jawbone […]
Ayooshi Mitra, Amity University, Kolkata A long time ago, a record of the “lost time” was discovered by some workers digging grounds for a power plant in New Zealand. The discovery was of a 60-ton trunk from a kauri tree (the largest species of trees in New Zealand). The tree was assumed to have been […]
PRIYANKA CHAKRABORTY, AMITY UNIVERSITY KOLKATA Scientists extracted remains from the Egg Mountain in Western Montana and studied the fossils of 22 individuals Filikomys primaeval (which translates to “youthful, friendly mouse”). The remains were about 75.5 million years old typically stuck together in groups of two to five, with at least 13 samples clustered within a […]
