Titan , the largest satellite of Saturn and second largest known satellite in our solar system, is much weirder than we might think. It is the only heavenly body, after earth, that contains surface liquids in stable forms and only moon with dense atmosphere. Cassini , a collaborative mission between NASA, ESA and ASI, has unveiled many secrets about Titan so far. The latest imagery from the Cassini probe claims that Titan's lakes may have been formed by exploding nitrogen bombs. Yes. their exist Nitrogen, an essential component for all life forms. Titan is mostly composed of icy and rocky materials. Scientists had long believed that these infamous lakes are a result of melting bedrock of ice by Methane. But a new data gathered by Cassini speaks otherwise. The nitrogen exploded below the surface due to increasing temperature resulting in craters, which were filled with liquids later.  No wonder, why NASA is planning a mission to explore this mysterious world by 2026. ...

A flaw has been identified in the popular app ‘WhatsApp’ that could allow crackers to manipulate messages raising the possibility of wrong information being spread by what seems to be a trusted source. Researchers have found three potential flaws that can be used to alter conversations. One, by the "Quote" feature in a group chat to change the appearance of the identity of a sender. Second lets a hacker replace the actual text of someone else’s reply with the wrong one. And the other, which has been fixed, can let a person send a private message to another group participant disguised as a public message to all members. So, when the targeted individual responds, it is visible to everyone in the group. The flaws might have weird consequences because 1.5 billion persons use the app for personal conversations, business and political purposes. For own safety update the 'Whatsapp' to the latest version as soon it's available on Play Store or App store.

If you are the one among the Android phone users, you must have been lured by the Apps  present on play store or the other third-party websites. Because these Applications are free doesn't really mean you don't have to pay for it. Now days the most important thing to sustain in the digital world are the Data and Information. Yes, you got it right, these apps are harvesting your personal data in return for some services. The funny thing is that we are the one who actually give them the accessibility to use our data. We don't think twice before we allow the permissions, these apps ask for. These data include phone's gallery, location history & live location access, wi-fi and Bluetooth information, Mobile data details, cloud access, phone and messaging details, browsing history and many more. For example a Flashlight App on Play Store may ask for the following data: Do you rally believe these permissions are required just for a simple service like Torch(fl...

As we have stepped into the Digital Era, the data and information have became one of the most important things in life. Strictly speaking, we depend on data like we do on our brain. And storing these tons of data securely is the biggest issue. Here comes the role of Secure Digital storage devices e.g. SD(Secure Digital) card, SS(Solid State) drives, Flash drives, Pen Drives, micro SD cards etc. You must have used these storing devices, but did you ever wondered how come these tiny chips let you enjoy colorful pictures and videos and other information when inserted into your mobile phones , camera, tablets, PCs etc.? Don't worry here we are to inform you. Before diving into it, we must be aware of some fundamentals of Digital Storage. Digital storage devices store data in the form of bits i.e. 0 and 1. For example, suppose we have to store an alphabet 'G', then it will be converted into a code containing a series of 0 & 1, also known as ASCII(American Standar...

String theory  We rely on string theory to understand and to combine the quantum theory and the gravity. As the name suggests, whole theory is based on string like structures. The one dimensional objects which only have length. The lies and move through background spacetime. The advance version of string theory i.e. superstring theory is considered as THEORY OF EVERYTHING . So what string theory exactly is ??? Strings are one dimensional objects that contain energy and by there flow, one can say that energy is moving. Suppose we take a long thread and tie a knot, it will became a loop, similarly strings are joined to make a loop known as Heterotic string. These are 5 independent strings theories, telling the same thing but in different dimensions. Combination of all the 5 string theories is known as S uperstring theory . Let us see how  it works... Consider a violin, the strings attached to it, are producing waves, which are the source of energy. Havin...

Now days , we all are familiar with the satellites wandering over our head and squeezing out information about our positions and locations. Of course it has made our life easier in most possible ways. But what will you say if these modern robots start spying on you? Will you really appreciate the beauty of technology when you are under 24x7 surveillance? Satellite companies say that they keep a everyone's data separate from any spying characteristics, but Peter Martinez of the Secure World Foundation told MIT Technology Review that it doesn't matter. Martinez said satellites don't need to identify faces to identify someone. If they can combine the images with data streams from sources like GPS, security cameras and social media posts, it's enough for them. Obviously government has defined rules and regulations but the breaches are as normal as a normal issue in this digital era. Ever wondered why satellite imagery is getting closer to a level that investor...
