Unraveling the Ribosome: Chemistry Nobel Awarded to Modelers of Living Cells' Protein-Maker Oct 8, 2009
This marks the second time in four years that the chemistry Nobel has been awarded to someone working with x-ray crystallography; in 2006 Roger Kornberg took the prize for detailing the structure of messenger RNA, which is the molecule that carries the information the ribosome uses to build proteins, such as insulin or hemoglobin.

Naturally-occurring Protection Against Severe Malaria Demonstrated Aug 25, 2009
The team lead by Miguel Soares had previously shown that, when Plasmodium multiplies inside red blood cells (the cells that transport oxygen from the lungs into tissues) it causes these cells to burst and to release hemoglobin (the protein to which oxygen binds inside red blood cells) into the blood stream. Once outside the red blood cells, hemoglobin itself can release its heme groups (the four iron centres through which oxygen binds to hemoglobin), which leads to the severe symptoms of malaria...
