It is an infectious and sometimes fatal viral disease. Affects cloven-hoofed animals, including domestic and wild bovids. The virus causes a high fever for two or three days, followed by blisters inside the mouth and on the feet that may rupture and cause lameness. The virus responsible for the disease is a picornavirus, the prototypic … Read more

Ballistic Missiles Ballistic missiles are powered by rockets initially but then follow an unpowered, parabolic, free-falling trajectory toward their targets. They are classified by the maximum distance that they can travel, which is a function of how powerful the missile’s engines (rockets) are and the weight of the missile’s payload, or warhead. To add more … Read more

Uranium is one of the fissile material which is used for power generations. But All isotopes are not categorised as fissile. The certain minimum standards have to be met to qualify as fissile material: It should be able to sustain the chain reaction. It should have a high probability of fission when bombarded with slow/fast … Read more

It also strives to enable genetic epidemiology and develop public health technologies applications using population genome data. IndiGen  project selected the 1000-odd persons from a pool of about 5,000 and sought to include representatives from every state … Read more

Allotrope: An element, in different forms, having different physical properties but similar chemical properties is known as allotropes of that element. Carbon has three well known allotropes which are graphite, diamond and buck minster fullerene. These are formed by carbon atoms. Following are the allotropes of carbon: Graphite:  Each carbon atom is bonded to three other carbon atoms … Read more

The first human vaccines against viruses were based using weaker or attenuated viruses to generate immunity. The smallpox vaccine used cowpox, a poxvirus that was similar enough to smallpox to protect against it but usually didn’t cause serious illness. Rabies was the first virus attenuated in a lab to create a vaccine for humans. Egg-Based … Read more
