Funny Octopi Use Tools Posted by Meera Dolasia on DOGO news
Octopi are smart creatures, we can't deny that. From knowing who will win the world cup to opening jars of jam, they have fascinated us with their intelligence. However, recently they have taken another step into intelligence: Mobile homes and armour. Using coconut shells from mollusk shells makes a lighter, effective defence that can be used as a home that can be moved around with ease. However, it does make them look awkward due to the fact that the coconuts are slightly bigger than them. Still, you can't help wonder what they will do next. Maybe create tools to help them hunt? Traps? We still don't know, but we can guess and hope that it won't make octopi the second smartest creatures on Earth and take over.

"DIRT" The Movie
In the movie, I was surprised to find that dirt is so important to our ecosystems and our lives, not to mention the one million, twelve thousand, nine hundred and eighty two species of animals and four million eight thousand and seventy two species of plant that cover the earth (The two large numbers are estimates). I am also surprised that dirt is filled with life and that without it non of us would be here today.
However, like Tatijana said, the movie was based on itself too much and didn't play the full devil's advocate. So, the movie did cause some major discussion around the class. Tatijana and I were in a deep discussion over which side was right. In the end, both sides of the coin decided that the case depended on a point of view, and so we both congratulated each other on their debating skills.

One Man's Quest For The Earth Posted on DOGO News by Meera Dolasia
When diving into the waters of Florida Keys at age of 13, Ken Nedimyer loved the coral and the waters of it. However, when in 1977 a cold rush of water killed most of the coral and then a disease came along, almost all of the coral was killed. The coral that wasn't killed was severely weakened.
When the coral was starting to recover, hurricanes hit the coast and killed so much coral that most was put on the endangered species list.
When Ken Nedimyer saw how much destruction had been placed on the innocent coral reef, he didn't know what to do. However, when some Staghorn coral grew in a fake underwater rock farm, he had an idea.
First, his daughter and he artificially cultivated the coral for a high school project. When this was a success, he decided to start growing some coral at the reefs. This was also a success, and now many coral "fields" have grown to make another ecosystem of the reef.

Black Nights, Blue Seas? Posted on DOGO news by Meera Dolasia
Over the last few weeks, San Diego's ocean has been bioluminescent over the last few weeks as The Red Tides dominated the area. For all those who don't know what The Red Tides are, it is when phytoplankton dominates the sea/ocean and turns the sea/ocean a red/purple/brown colour due to the amount of numbers. The phytoplankton seem to be turning bioluminescent whenever something hits it. Toxic? I think not!
These little fellas aren't toxic, and probably evolved for some reason. Whatever it is, its COOL!

Waste into Fuel: A New Beginning? Posted by Meera Dolasia on DOGO NEWS
Finding new green, clean energy sources to replace fossil fuels is one of man's toughest challenges. Hydrogen is a viable replacement, but it doesn't occur naturally and uses energy getting it... Until now.
A group of scientists found bacteria that could extract hydrogen and give it off , but fuelling the bacteria was also the problem. The process of desalination used energy, so they thought that resalination would release energy. It worked; if they managed to put some bacteria between the sea/ocean and a wastewater treatment centre, it would be a dream. However, this has only worked in a lab and so now they go on to larger scale, and on the economic scale. If it works on all scales, we would be one step closer to the best species on Earth (possibly)
