Magnetic Feilds Set Stage for Birth of New Stars
November 16, 2011
For the first time, astronomers measured the alignment of magnetic feilds in gigantic clouds of gas and dust in a distant galaxy. Molecular clouds consist mainly of hydrogen molecules. Stars and their planets are born when giant clouds of interstellar gas and dust collapse. If someone traces the distribution of clouds in a spiral galaxy like the Milky Way galaxy, then they find that they are lined up along the spiral arms. Magnetic feilds can be used to impose order.

Small Molecules Can Starve Cancer Cells
Date: October 9, 2011
Summary (8-10 sentences)
All cells in our body have a system that can handle cellular waste and release building blocks for recycling. The underlining mechanism is called autophagy which means “self-eating.” The molecules are called microRNA-101 and are found naturally in our body. MicroRNA-101 can turn off specific genes and inhibit autography in cancer cells. The next step for the researchers is to investigate whether other microRNA molecules are involved in the regulation of autography in cancer cells. After that they will take a closer look at the job of microRNA-101 in normal development of our organism and in the development of cancer.
What you found most interesting about the article and why (4-6 sentences)
I found it interesting that we have our own anticancer cell in our body. I found that interesting because even though we have that cell, people still get cancer. But if they put more microRNA-101 into our system it kills off cancer.
