The sun and it's eventual dangers!

Red dwarf

The sun:
The thing that keeps humanity alive. But It's star and all stars come to an end right?What were to happen if our sun came to an end.The way this will happen is when the sun runs out of it fuel (hydrogen). The sun will collapse but as it does that gravity heats up the star to millions of degrees causing it to expand about 3 time its size.As it expands it engulfs Mercury,Venus and possibly Earth.This is called a red dwarf because when it stops expanding it shrinks and gives of little specs of light BUT there is no reason to worry because this wont happen for another 6 billion years.

Amazing animals: Angler fish

The Angler fish is one of the most ugliest animals in existence, but there way of luring and hunting is very impressive. Their height can vary from 20cm to 1 meter and they weigh around 50kg. These fish are named after their characteristic methods of predation.  Anglerfish typically have at least one long filament sprouting from the middle of the head this resembles the preys animal  and they to act as bait to lure other predators close enough for the anglerfish to devour them whole. The jaws are triggered in automatic reflex by contact with the tentacle. 

Mind controlling parasites: Green banded brodsac

 This is a kind of worm that likes to live inside of birds. But to get inside of a bird it has to get into a birds food. Certain snails like to eat bird feces which is where the Green banded brodsac larvae end up. When the snail finds this piece of bird feces it will eat it, but little dose it know that it is also eating a parasite. Once the Green banded brodsac is inside the caterpillar it takes over its brain and makes it go to a really open place, it then works its way into its antenna and moves backward and forwards making the birds think it is a maggot. The bird then eats it and the Green banded brodsac can now reproduce and continue its life cycle.

The immortal jellyfish: Turritopsis dohrnii

This jellyfish is the only animal that we know of that can reverting back to a younger stage of its life cycle, it dose this when it is facing starvation or other stresses in its environment. To reverse the aging cycle the Turritopsis dohrnii will change back to the polyp stage of it's life cycle from here it can grow more cells and continue life as normal. Although they can be killed through infection, disease of if they get eaten.

Transdifferentiation plays a big role in this because every cell can be changed into other cells for example a lung cell could be recycled into a skin cell. This isn't unique to the Turritopsis dohrnii because if you take a lens out of a chicken the iris will turn into lens cells. 
This extraordinary specie of jelly fish is extremely important to scientists because they are always looking to reasearch new ways to regenerate tissues in the body.

Ants that do slavery

The Polyergus breviceps is a specie of ant that doesn't know how to look after its self of its offspring The workers do not forage for food, feed the young or the queen, or even clean up their own nest. There only mean of survival is to invade other ants nests and take their pupae, once hatched they become workers of a mixed nest. This sort of relationship is not unique, of the approximately 8,800 species of ants, at least 200 have evolved some form of symbiotic relationship with one another. What makes Polyergus special is the way a newly mated queen can, all by herself, take over a Formica nest and start a new colony.
These type of ants are only found in america so they will not be taking over the world of ants anytime soon.

Facts about super volcanoes.

• A super volcanic eruption occurs somewhere in the world approximately every 50,000 years or so.
• The last super volcanic eruption happened around 74,000 years ago in Indonesia so we are probably overdue for one.
• Yellowstone has experienced three super volcanic eruptions in the past 2.1 million years, they were 2.1 million years ago, 1.3 million years ago and 640,000 years ago. Disturbingly, this cycle of approximately 600-700,000 years suggests another eruption could be brewing.
•  A super eruption at Yellowstone would eject over 2,000 million tonnes of sulfuric acid into the stratosphere.
  This would form a veil around the earth that deflects sunlight, triggering a catastrophic volcanic winter.
  Temperatures would drop by up to 12 degrees in the northern hemisphere and up to 16 degrees in the southern hemisphere.
  
  

  

Mushrooms could replace plastic

Plastic we all use it on a daily basis but it is one of the most polluting and toxic materials that we use. Eden Bayor co-founded a company called mylobond. The idea was to replace the Styrofoam with the 100% biodegradable material from mushroom. They called it mushroom packaging. Mushrooms naturally create a root system called mycelium this is what holds the mushroom together acting like glue. This mushrooms packaging is 100% recyclable and uses 1/10th of the cost of making styofram.
