‘GermiKlean’: Developed by DRDO to sanitise uniforms of police and security personnel

The Defence Research and Development Organization has developed ‘GermiKlean’. GermiKlean is a sanitising chamber that can be used to sanitise uniforms of security and police personnel.


The DRDO developed the sanitizing chamber after the Delhi Police raised their requirement of sanitizing their helmets, uniforms, cane shields, etc.

About GermiKlean

GermiKlean is capable of sanitizing 25 pairs of uniforms within 15 minutes using dry heat treatment. Dry heating of an article is accomplished by conduction. Heat is absorbed by the exterior surface of the article and passed inward. Dry heat kills micro organisms by causing denaturation of proteins. Denaturation is a process in which the nucleic acids lose the quaternary structure. This kills the micro organisms.

Other measures

The DRDO has also designed sanitisation tunnel. It has come up with an idea of a mat that can be used to sanitise foot.

Saturn Moon Titan: Drifting faster than before

The moon of Saturn, Titan is drifting away faster than before. This has been identified by the researchers in NASA and also scientists in Italian Space Agency.


According to the data received from the Cassini Spacecraft of NASA, scientists believed that the Titan has been moving away from its host planet Saturn. However, the recent studies say that the moon is drifting 100 times faster. This is about 4 inches every year.

Science of drifting moons

The moons begin drifting away from their host planets because as the moons orbit, their gravitational pull on the planet creates temporary bulge in the planet. This bulge in turn increases the energy exerted by the planet on its moon. It also transfers the subsiding and bulging energy to its moon.

The earth’s own moon drifts 1.5 inches from the Earth every year.

There are around 82 moons that are orbiting Saturn.


The Cassini Space Craft Mission, or the Cassini-Huygens Mission is a joint space mission of NASA. Italian Space Agency and the European Space Agency. The mission was launched to study saturn, its moons, and rings.
