All of this has happened before

By
NPR had this report about the mass extinction of frogs in the Amazon rainforest on a few days ago. Scientists are concerned because they believe climate change has led to the over growth of a fungus which they believe is responsible for a mass extinction of frog species going on in the rainforest. My thoughts on this are, there have been mass extinctions before. The diversity of species of frogs in the rainforest arose after some past extinction event. If the diversity that we have become familiar with came about after a previous extinction event wouldn't the diversity of species establish itself again? I think the answer to that question is yes.

That morning after I got tired of hauling him back from the edge of the bed he was intent on crawling over I took him downstairs to safer level terrain. I turned on the television to check the news like I did every morning back then. At first I was horrified by what I saw. One smoldering tower.

But the news kept coming about just how wretched humanity had been to itself that day. The ...

Treating autism as traumatic brain injury

By
I've been doing research into autism, dyspraxia, how the normal brain works, and how an autistic/dyspraxic brain works (or doesn't work). Traumatic injury to different parts of the brain can cause the same problems suffered by autistic and dyspraxic children. Compare this list of the functions of different parts of the brain and the problems caused by injuries to those areas with these descriptions of dyspraxia and autism. What is Developmental Dyspraxia? Developmental dyspraxia is a disorder characterized by an impairment in the ability to plan and carry out sensory and motor tasks. Generally, individuals with the disorder appear "out of sync" with their environment. Symptoms vary and may include poor balance and coordination, clumsiness, vision problems, perception difficulties, emotional and behavioral problems, difficulty with reading, writing, and speaking, poor social skills, poor posture, and poor short-term memory. Although individuals with the disorder may b...
