2019’s prestigious Nobel Prize in Physics is claimed by three phenomenal scientists – James Peebles, Michel Mayor and Didier Queloz for groundbreaking discoveries of the Universe. This research helped us to progress in the quest to understand the development of the Universe and Earth’s place in it.
Cryogenic technology refers to the technology that operates at a very low temperature, generally below 123K(-1500C). The temperature is such that the properties of materials that operate under it get drastically changed.
Bacteria do not attack tooth suddenly or by chance, they grow over time due to the consumption of excess sweets, beverages containing acids, food debris, improper brushing, etc. It is essential to understand that once these microbes stick onto the tooth surface it creates an attachment between the microbe enzyme and the contents of the tooth, the microbes containing acid start deteriorating the tooth material initiating the dissolution of enamel, thus reaching the dentin over time and hence reaching the root canal stage.
Forensic Entomology is a sub-field of forensic biology. It applies the knowledge of the field of entomology to identify, collect, and study the type of insects found in close proximity of the cadaver in solving cases of crimes. In this, the biology and ecology of insects are studied to determine the time since death or post-mortem interval.
Asphalt, also known as bitumen, is a refined semi-solid product of petroleum. Also found in natural deposits, It occurs as a black viscous liquid. The asphalt which naturally occurs is commonly called as “crude bitumen,” whereas the asphalt obtained by fractional distillation of crude oil at 525 degrees Celcius is referred to as “refined bitumen.”
Galaxy (adopted from Greek word ‘galactos’ meaning milk) is a complex structure of a gargantuan collection of dust, gas, billions of stars and their stellar systems, compact objects and dark matter which is held by gravity. Galaxies are the charms of the universe forming into groups, clusters and huge structures called superclusters, appear as filaments neighbouring large void regions!
