Poison Mutualism!


This picture shows a "hairy rope" climbing up a tree. This is a form of mutualism because both the poison and tree are benefiting. The symbiotic relationship of mutualism is when two organisms benefit from each other. This is an example of this, because the tree benefits from the protection of the poison. Also, the poison benefits from the tree by receiving all the necessary supplies.

Trees of Death!


Look at this beautiful biotic limiting factor. This tree is an important part of nature. This tree limits the area around it by limiting the sunlight for the surrounding shrubs. The tree also limits the grass under it by releasing acidic fluids. The tree does this so it doesn't have to compete with other trees and shrubs.

Higher risk of heart disease for short people!!!!!!!!!!


50 years of controversy finally coming to an end. Your height matters if you want to live long and healthy. Gender doesn't matter either. Studies show that short adults are 1.5 times more likely to die from a heart attack, cardiovascular or heart disease. As heart disease claims short adults more likely, it may be because of the health of the people. Short healthy people are more likely to live than an obese tall person. Height is a factor in heart disease, but its not the only factor. Your height as a child could also be a factor in this startling discovery. Studies also show that kids that are born short are short as adults. Unhealthy people are just as perceptible to heart disease as normal short people.

Scientists can read your brain?!?!?!?!?!?!

Scientists can read your brain using a commonly used system-Brain scans. Brain scans can read your brain when you are reminiscing on a memory. One example they used was when they brought volunteers to watch similar videos. Then the scientists ask the volunteers to remember what they had watched. When the scientists scan their brains there is a trace of memory. The scientists use an algorithm to find a trace and pattern in the volunteers memory. Scientists now wish to bring them back to see a slowly diminishing trace or diminished trace.

Math Project-Child Soldiers

300,000 kids have died in Africa so far. This atrocity has started around 2007 and has become a worldwide issue. At this rate, 1,800,000 kids will die by 2020. In 13 years more than a million kids die. Can we let the whole population of African children die? Soon enough it might happen so we need to figure out how to stop this "pandemic". A pandemic of child abuse has struck Africa and we need to prevent millions of kids from death. We can't let millions of poor innocent children for an unethical reason. Saving adults. If kids die at this rate there will only be a handful of adults left.

Tiny Nuclear Batteries to Power Micro Devices

Have you ever seen a nuclear battery? Typical chemical batteries are the basic ones. In your remote is there a small nuclear battery with tritium. Believe it or not its here and has a semiconductor that harvests electrons.Although it won't power your laptop or ipod it is being developed by betavoltaics. This is actually a microwatt but it is one step closer to the future. A green world can help especially if we can figure out how to harness more energy. This actually happens to have an effect on the military. In theory betavoltaics is the main energy source and if we can expand it we will have a great future.
