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...

1. Why there are curls drawn at the center of moving turbine in an airplane jet engine? Ans. You must be aware of the fact that the jet engines of any commercial airplane are capable of sucking an adult if he/she passes before it. The human body cuts into pieces and a red soup like thing drains out from the back of the jet engine. To avoid this type of accident, and to inform the workers whether the engine is ON or not, a curl is drawn in the front which when rotates seems like a spinning whirlpool. It also helps in keeping out birds. 2.Why lights in the passenger cabin dims during take-off and landing? Ans. If you have ever been in an airplane, you must have observed that the lights inside the passenger cabin are dimmed during take-off and landing, at night. This is because of the fact that 80% of air accidents occur during take-off and landing. And our eyes might take about 10 mins to adapt in the darkness after a sudden light-off condition. To aid the chances of surv...

After the successful launch of chandrayan-2 ISRO is planning to cement its another pillar in the area of Aerospace. India is setting its foot on the Moon, then why leave the Life-giver, the Sun unexplored. Yes, you heard it right India is planning a new mission to study the Sun. The spacecraft named, " Aditya-L1 " (Aditya means the Sun)  has been chosen for this purpose. The mission will probably be started by the end of 2020. Things you must know about Aditya L1. It was originally named Aditya-1, which was made to carry just one payload, VELC (Visible Emision Line Coronogaph). Aditya-1 was a 400 kg satellite scheduled to be launched at 800 km from earth surface in low earth orbit. Later it was realized that if it is launched at " Lagarangian point ", it will be fee from any hinderance e.g. eclipse. Then the mission name was named Aditya L1 mission . [Lagarangian point is a point between earth and sun where the satellite will lie stably rel...

Did you know these interesting facts??? 1.A human can snore louder than a drilling machine. 2.Our tongue prints are unique just like our fingerprints. 3.The electricity generated in our brain is capable enough to light a small bulb. 4.the hair present on a human head can lift weight up to 10 tonnes. 5.Our body contain enough iron to make small nail. 6.We can't sneeze with both our eyes opened. 7.Almost 8% human in the world are color blind. 8.We shiver in cold because it generates heat. 9.When you sneeze, your heart stops for a milisecond. So, when someone says, "God bless you" after you sneeze, he/she really cares for you. 10.Every human spent about half an hour as a single cell in the womb.
