Memory is so fundamental to human behavior that any impairment to it can severely impact our daily life. Did it ever happen that you forgot the name of the person you just met? How do we remember some stuffs for decades and some fade after a few moments? What actually is that makes the difference between long-lasting memories and volatile ones? After several tests on mouse, Caltech researchers have finally discovered that the strong memories are results of the synchronized "teams of neurons" that provide redundancy to retain memories over long time. The team of researchers developed a test to study mice's neural activity as their brain resembles that of human in many ways. The result showed that more the quantity of neurons, longer will the memory last. For years, people believe that practicing an action more, brings better chance to remember it later as the conventional theories about  human memory storage say that making a memory more stable requires the s

We all are living in a world full of interesting facts and mind blowing stories, and for many of us, one of the most questionable statement is the -"CREATION OF THE UNIVERSE". We live in a beautiful blue planet, earth but why are we here? Why is this so? Why the universe is in the way that it is?? Almost every religions believe that the god, a super power led to creation of us. Lord Krishna has the whole universe in his mouth, African god 'Mbombo' vomited the universe and there are infinitely many never-ending stories about God all over the planet but all are not acceptable. Different stories across the world lead to the two theories explaining the creation of the Universe: 1) Steady State Theory 2) Big Bang Theory Steady-state Theory Some scholars believe in the Steady State Theory. According to this theory, Universe was always the same. It has neither the beginning nor the end. This theory insists on the constant density of the universe. As we kno

Don't be fooled by its name. A black hole is not really a hole as its name suggests. Before diving into the topic let's first be familiar with a few terms. Image of a Black Hole Escape velocity - The lowest velocity with which when an object is thrown from any cosmic body [planets, stars etc] escapes or moves out of its gravitational pull. The escape velocity of the Earth is 11.2 Km/s. Event Horizon - The boundary after which no light or other radiation can move out after striking a black hole. Light cant escape out completely from the pull of a black hole but it does come to a certain limit, that's event horizon of a black hole. A Black Hole is a super dense, massive object with an infinitesimally small volume having escape velocity higher than the velocity of light. And nothing can move faster than light so, nothing can escape out of a black hole. This is the reason it appears completely dark because even light can't reflect back from it. Think of a star

One can question the existence of the God, the almighty, but can't question the belief of the people. The most controversial topic of current time and the never ending debate between religion and science- THE EXISTENCE OF THE GOD. We all must have heard one or more of the words: God, Allah, Bhagwan, the Almighty, Ishwar etc since the day we stepped into this massive universe. These all point to the same power, the supreme one. The power that drives the universe, that drives you and me and every other creature. The force that exists within each and every elementary particle. Some people having keen interest to question all the things around them, known as Scientist, believe what they see and what get through various complex equations. And 'the existence of the God' too didn't remain untouched. Perhaps, there is nothing wrong in finding what's hidden inside the nature's womb. It just get us closer to the mighty universe. That's what a scientist alw

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. Having differe

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
