How is atomic bomb different from hydrogen bomb?

How is atomic bomb different from hydrogen bomb? A hydrogen bomb, also called a thermonuclear bomb or an H-bomb. It is far more powerful than the relatively simple atomic weapons. It uses a second stage of reactions to magnify the force of an atomic explosion. The second stage is fusion. Fusion is mashing hydrogen atomsContinue reading “How is atomic bomb different from hydrogen bomb?”

Biofilms

Biofilms: A biofilm is an assemblage of microbial cells that is irreversibly associated (not removed by gentle rinsing) with a surface and enclosed in a matrix of primarily polysaccharide material. Van Leeuwenhoek, using his simple microscopes, first observed microorganisms on tooth surfaces and can be credited with the discovery of microbial biofilms. Microorganisms that formContinue reading “Biofilms”

Solar storms:

Solar storms: It could refer to the following: Coronal mass ejection: Corona, the outer solar atmosphere, is structured by strong magnetic fields. Where these fields are closed, often above sunspot groups, the confined solar atmosphere can suddenly and violently release bubbles of gas and magnetic fields called coronal mass ejections. Solar flares: These are intense burst ofContinue reading “Solar storms:”

GM mosquitoes

To suppress wild female Aedes aegypti mosquito populations that cause dengue, chikungunya and Zika were launched in Maharashtra’s Jalna district. The technology uses genetically modified male Aedes aegypti mosquitoes that carry a dominant lethal gene. When male GM mosquitoes mate with wild female mosquitoes the lethal gene is passed on to offspring. The lethal gene in the offspring kills theContinue reading “GM mosquitoes”
