The Crab Nebula

          "The Crab Nebula, the dusty remains of an exploded star, has unleashed a surprisingly massive flare that is five times more powerful than any eruption previously seen from the celestial object, leaving scientists struggling to explain the event," NASA says. 
             "The Crab Nebula's strong outburst lasted six days, and its exact cause has scientists scratching their heads, especially since the superflare followed an earlier gamma-ray flare from the nebula".
             This is definitely something new that is discovered. Though it may not affect us all the way on Earth, but this can always increase our knowledge about the outside world. 
              The Crab Nebula teaches me that even though a star explodes, it can always make a massive flare. This also shows that the universe is full of surprises and that it can always show you something you never expected.

Zombie Ants?

           "Problem: you’re a fungus that can only flourish at a certain temperature, humidity, location and distance from the ground but can’t do the legwork to find that perfect spot yourself. Solution: hijack an ant’s body to do the work for you—and then inhabit it."
           Everyone knows that fungi can't move from one place to another, but did anyone know that they can climb into an ants' body and control them? Well, now scientists have figured out that Ophiocordyceps unilateralis fungus can infect Camponotus leonardi ants that live in tropical rainforest trees. Once the ant is infected, the spore-possessed ant will climb down from its normal habitat and bite down, with what the authors call a "death grip" on a leaf and then die. 

            Something like this is definitely a new and huge discovery. But even though this scientific discovery does not affect me, it is a new fact that I have just learned.  Every day, every hour, we learn something knew; but can something like this affect us?
