Know Your Jewels

Gemstone or Jewel?

Gemstone or jewel is simply a mineral with a crystalline structure. Gemstones are created through time by natural forces occurring deep within the earth's crust. An assortment of minerals and trace elements, melted together by extreme temperature and pressure, conspire to form a crystal. Those crystals will eventually find its way to the surface via volcanic eruption or seismic uplifting, and ultimately, into the jewellery store to our finger, neck or in ear! Gemstones come in every conceivable geometric shape, and in every colour of the rainbow.

Electric vehicles can be so quiet that it can pose a new risk on the road

After years of research and trying to make car more and more quiet who would have thought that one day we would have to put up so much efforts and millions of dollars to add artificial sound? Yes that is the current concern regarding “Electric Vehicles”. Electric vehicles are extremely quite. Infact the only noises that come out of an electric vehicle are from tires, air and occasionally high-pitched whine of electronic parts.

A Robotic Hand With Feelings

The researchers at the Swiss Federal Institute of Technology in Lausanne, Switzerland, have found a way to implant sensations in prosthetics (artificial body parts). This advancement has led to amazing results in Dennis Aabo Sorensen’s life, a Dutchman who lost his hand nine years ago in a fireworks accident. He is now able to feel different kinds of pressure on three fingers of a prosthetic robotic hand.
