Top 5 Phenomenon that Science Still Couldn't Explain.

1.The Taos Hum


In the small city of Taos, New Mexico, some residents and visitors for years have been annoyed and puzzled by a mysterious and faint low-frequency hum in the desert air. Oddly, only about 2 percent of Taos residents report hearing the sound. Some believe it is caused by unusual acoustics; others suspect mass hysteria or some secret, sinister purpose. Whether described as a whir, hum, or buzz and whether psychological, natural, or supernatural no one has yet been able to locate the sound's origin. Thing is, a survey revealed that those who claim to hear the sounds actually hear many different sounds, suggesting the experiences may be subjective, not actually objective sounds (and pretty certainly not one particular sound).


2.UFO's


There is no doubt that UFOs (Unidentified Flying Objects) exist — many people see things in the skies that they cannot identify, ranging from aircraft to meteors. Whether or not any of those objects and lights are alien spacecraft is another matter entirely; given the fantastic distances and effort involved in just getting to Earth from across the universe, such a scenario seems unlikely.

Still, while careful investigation has revealed known causes for most sighting reports, some UFO incidents will always remain unexplained.

3.Hexagon Shaped storm on Saturn's north pole


At Saturn's North Pole, there's a weather system the size of two eaths in the curious shape of a hexagon. The storm was photographed and observed for years by NASA's Cassini spacecraft, but it remains mysterious.

The only other naturally occurring hexagonal shape scientists have found is in crystals, so they have no idea how Saturn's storm came to look like this. To make matters more confusing, the storm appears to have changed color, shifting from turquoise to yellow over just a few years.

4.Dark Matter 


Planets, stars, asteroids, galaxies – the things that we can actually see – make up less than 5% of the total universe. Scientists think another ~25% is a strange substance called dark matter: we can’t see it, we don’t understand it, but we’re pretty sure it’s out there because everything moves to its gravitational tune.

Scientists believe that dark matter acts like a spider’s web, holding fast-moving galaxies together. And there’s so much of this stuff that it bends the appearance of space, so that when astronomers observe distant galaxies, they often appear distorted.

We have plenty of evidence that dark matter exists, but as for what it is, that remains a mystery. Some think dark matter is composed of an undiscovered particle or particles, others believe it’s an undiscovered property of gravity. Whatever the truth, dark matter is a real puzzle, and it’s proved hugely tricky to pin down.


5.Ghosts


Modern scientists haven’t delved into this topic all that much, but a few compelling explanations exist. One has to do with infrasound, or low-frequency sounds inaudible to humans but that storms and even household appliances can generate. Such rumbles can vibrate human organs and make people a sense of unease. Infrasound vibrations can also mess with vision and make people think they are seeing things. Another idea is that drafts may create “cold spots” thought to be signs of spirits. A final theory is that some observations of ghosts may have been due to hallucinations caused by carbon monoxide poisoning.

Accomplishments in 3-D Bioprinting

As the name suggests, in 3-D bio printing the organs or body parts or biological items are 3-D printed using special type of 3-D printers. But Now you can even print "Ebola Virus" or such other viruses as now its "Genome"  is publically available.   In past years what we thought as impossible is now all possible, we thought of flying cars we get it, we thought of humans in space, we did it. There are a lot of such things that we think today are impossible, but one day they will be possible. Who would have thought that we will be printing viruses but we did.  But the much it sounds exciting, it is that much dangerous too as it can be a huge danger to the humans.  So we should be careful while handling such a technology.

5 Mind blowing science fact that you didn't(might) know.

  1.The average human body carries ten times more bacterial cells than human cells All the bacteria living inside you could fill a half-gallon jug — there are 10 times more bacterial cells in your body than human cells , according to Carolyn Bohach, a microbiologist at the University of Idaho. Don’t worry, though: most of these bacteria are helpful. In fact, we couldn’t survive without them. 2.Grasshoppers have ears in their bellies Unlike humans, grasshoppers do not have ears on the side of their heads. Like the ears of people, the grasshopper sound detector is a thin membrane called a tympanum, or “eardrum”. In adults, the tympanum is covered and protected by the wings, and allows the grasshopper to hear the songs of its fellow grasshoppers. 3. There is enough DNA in the average person’s body to stretch from the sun to Pluto and back — 17 times There are about 37 trillion cells in the human body, so if you were to uncoil all of the DNA encased in each cell and place the molecule...

What are Antiparticles? Is there something that we should worry about?

  Simply put , antiparticles are the opposite of the subatomic particles but with different charge and different magnetic properties . For example the antiparticle of electron is a particle with same mass but different charge , in this case positive charge and it is commonly referred to as Positron.. While the electron has a negative electric charge, the positron has a positive electric charge, and is produced naturally in certain types of radioactive decay . The opposite is also true , the antiparticle of the positron is the electron. Particle–antiparticle pairs can annihilate each other, producing photons ; since the charges of the particle and antiparticle are opposite, total charge is conserved. For example, the positrons produced in natural radioactive decay quickly annihilate themselves with electrons, producing pairs of gamma rays . It is not possible to create an antiparticle without either destroying another particle of the same charge (as is for instance the case when an...
