week 5

DNA
Got this off of Flickr-cc.


1. Topic: Researchers traces evolution to the DNA level through snapshots of 40,000 generations.

2. Article Title: Researchers track evolution through snapshots of 40,000 generations.

3. Article Source: Arstechnica

4. Summary: In 1988, Richard Lenski's lab begin with an experiment of a set of 12 bacterial cultures was started and was given a burst of sugar every day. The goal was to be able to follow major evolutionary innovations as bacteria try to outcompete their peers under near-starvation. Then in 2008, one of the 12 cultures had its big breakthrough, a sudden burst of growth powered by citrate, a chemical that was present in the mix, but not normally used by bacteria.

    5. Reaction: This events tells how bacteria can multiply. This event really don't effect me or to other people. It could effect how we look at bacteria and how it grows. Bacteria can grow amazingly and we need to learn more about it, because some bacteria can maybe help us get better of we get sick or need medicine to get better. This event could maybe lead to something greater and more amazing things.

      6. World Impact: Doing this experiment could make a chain that could lead to great things in the future. This world is getting more and more technology each and every day. DNA is very important in many different ways.
