Using Brain Cells Made From Skin to Treat Parkinson's Disease by JK
People with Parkinson’s disease have to take drugs, which do not work so well all the time. Scientists are now working to treat Parkinson’s disease(disease of the nervous system that causes brain problems and a lack of neurotransmitters-hormones for moving) by making new brain cells from skin. First, a skin cell is infected with harmless viruses. These viruses have genes that enables transcription. With specific types of protein(that previously took part in making neurons), it is converted into a neuron of the brain.
"Natural" Selection? By Pauli
While browsing through the BBC news website I came across this story: http://www.bbc.co.uk/nature/14479661. According to the article, on August 11th, a new colony of rare species of spider was introduced into a natural reserve in Dorset, England. They were so rare that there was only an estimated number of 56 remaining in 1994. Through conservation efforts, the population has now grown to around 1000. They did this through the use of water bottles filled with heather and moss, which simulates their underground habitat.
While the preservation of a species may seem a noble act, are not the people conducting this reintroduction of a species circumventing natural selection? Shouldn’t nature dictate the survival of a species?
