Earth: Wild Fires Burning Up

Scientist are noticing a trend in the wildfires that burned in the U.S.
on the average of acres burned over time

There has been a deep concern in the past year about how the weather is a hazard for hot states. In the state of Arizona there has been research since a wildfire cause by a lighting strike in Yarnell, Arizona. In was a hot, dry day when the fire vastly spread causing 19 firefighters died trying to put out the 8,400 acres of burning land. This all took place the summer of last year, which is a basis to the concern people are having of possible fires this year.

There rapid spreading fires are becoming more common in the United States as the years progress, being the climate change the worst enemy in this case. The increase of temperature in the Earth's atmosphere causes hotter temperatures that makes snow to melt faster in the year and make droughts worse. These dry seasons makes fires last longer, weaken plants and dry out vegetation that is a source that can cause fires to spread easily.

This is a situation that impacts anyone who is aware of it, specially the people who live in dry states. But due to technology advances, "... scientists are getting better at predicting where and were the fires might occur, which helps firefighters prepare to stop them before they get out of control,"says Gregg Garfin in Science Daily. This is a relief for many people and is a relief for many other countries that may be going through the same thing. Thing like this have never been a great concern in El Salvador, but there is a dry season (summer). It is of great concern that anything like this may occur in this small country, but people need to be prepared for anything disastrous that may happen.

Disappearing Ghost-Octopus

This video about an octopus camouflaging is very interesting. The octopus has perfectly adapted and camouflaged himself to a coral, where he is impossible to see. We are aware the octopus is there until its alarmed and is forced to scape from the unknown man with a camera. 

A marine biologist, named Roger Hanlon, was startled at the appearance of this particular marine creature. He had no idea it was there, and still does not know how this eight armed creature could do such thing. With his research group, Hanlon is investigating underwater creatures called cephalapods, which include suit, cuttlefish and octopi. The researchers are still trying to figure out how the octopus could camouflage to such an identical appearance to the natural object it was against. The biologists conclusion was that pigments of the skin called chromatophores are the cells that can create the skin to match the color and textures of its surroundings. 

Chromatophores

The natural world is so amazing. Its unbelievable that animals can become their surroundings, and adapt so well to them. For me, the idea of camouflage is so strange and uniquely amazing that makes me what to camouflage. It is so great that this tool that some animals have, help them disappear and protect themselves from bigger animals that can hurt or eat them. Its almost like being invisible, which is an awesome concept. Another thing from this article, besides the amazing ghost-octopus, was that these octopi are color blind. Just like Hanlon said,“The amazing thing is that these animals are color blind yet they are capable of creating color-match patterns,” which is insane if you ask me. I definitely learned a lot with this article about how amazing the natural world really is.

Niels Bohr

How did he contribute in the develpement of the Atomic Theory?

Niels Bohr is a Copenhagen Physists that came up with the Electron Theory. This theory stated that electrons orbit the nucleus in different energy levels much like the planets orbit the sun.
