Familial traits, disease risks and now, Faces!

How very often do we see forensic experts on TV, nab the killer using trace amounts of DNA that were found on the carpet or victim’s clothing? While these actors convincingly make the process seem very simple and quick, it is only the people who work in the area of forensics know how difficult and tedious the entire process is. The trick is not only in getting that little amount of blood/ saliva/ skin sample from the crime scene but also having a sturdy database of DNA markers such as CODIS to compare the results against. Without a database (which, not to forget, takes years of data gathering to make), even with bucket loads of DNA to test, a forensic expert would not be able to link the the suspect to the crime scene. But what if we told you that one could now simply get a 3D sketch of the person whose DNA was found at the crime scene. Wouldn’t that make the job of forensic experts and the cops much easier. Well, recent study published under the guidance of Dr. Mark S

We Muggles may not possess magical powers to conjure an invisibility cloak, but we surely have technology and genius, to fashion ourselves one. A simple principle exists behind the theory of invisibility. We can only see objects which reflect light incident on them, so in order to make any material or object invisible the reflection of light should be disabled. This is a simple concept but its execution is extremely difficult, and until now it was considered almost impossible. The phenomenon was reality with the use of artificially structured materials known as “metamaterials”. Metamaterials are unique materials which defy the natural law of absorption of light by materials which are consid
