From Old Vials, New Hints on Origin of Life
Just over 50 years ago, with the help of ammonia, methane, hydrogen, water and electrical sparks, amino acids were formed by Dr. Miller. The problem is that the amino acids didn't get anymore complex. Scientists now question whether or not the air 50 years ago was different than the air today. One of Miller's graduate students had injected steam onto the sparks in hopes of finding a solution but only produced what could be found in a lagoon. With the help of another graduate student, the discovery of 22 amino acids occurred. This experiment has given hope to the discovery of new things.
4 comments:
1. It was easy to read
2. Not to many confusing facts, just the right amount
3. Good transitions
1. Could have had a little more information
2. Could have gone more in depth
1. I learned that the air 50 years ago could have different than the air today
1 - simple, legible
2 - to the point
3 - good summarizing
1 - maybe a little more info would be good
2 - more detail
1 - I learned that a couple students had discovered new amino acids.
Jessica nicely condensed a long article into a nice short and easy to read summary. Also, she chose a very interesting topic and she clearly stated the most important facts.
I thought it was a little confusing as to what the new discovery was. Also, she could have been a little more specific.
I learned also that during the original experiment the air was different than the air today, which struck me and odd.
3 Things well done:
1. Article was of a very interesting topic.
2. The summary paraphrased in short order a much longer article.
3. Well written in a concise style.
2 Things to be improved:
1. The summary lacked any substantial analysis.
2. The summary was rather abrupt in its introduction of the topic - a broad introductory sentence explaining the subject matter of the article would have been helpful
1 Interesting thing learned:
1. I was unaware that scientists were so close to artificially creating life.
