Washington, March 26 : New results from NASA's Chandra X-ray Observatory have suggested that a special class of black holes have a mechanism for regulating the rate at which they grow, and can shut off the high-speed jets they produce.

Some stellar-mass black holes launch powerful jets of particles and radiation, like seen in quasars, and are called "micro-quasars".

The new study looks at a famous micro-quasar in our own Galaxy, and regions close to its event horizon, or point of no return.

It concluded that invading diseases do not always progress in an orderly, constant rate.

They found that chronic insomnia disrupts one of these two hormones.
