Midden is an archeological term meaning roughly "garbage pile". The Blood Typing Game - about blood groups, blood typing and blood transfusions What happens if you get a blood transfusion with the wrong blood type? Even though a patient's own blood type is the first choice for blood transfusions, it's not always available at the blood bank. Try to save some patients' lives and learn about human blood types!

Small World of Words Project Welcome to the small world of words project! Last modified: April 16, 2014 Voor Nederlandstalige informatie, klik hier The small world of words project is a large-scale scientific study that aims to build a map of the human lexicon in the major languages of the world and make this information widely available. In contrast to a thesaurus or dictionary, this lexicon provides insight into what words and what part of their meaning are central in the human mind. This way it enables psychologists, linguists, neuroscientists and others to test new theories about how we represent and process language. Current Project

The odd structures are called G-quadruplexes because they form in regions of deoxyribonucleic acid (DNA) that are full of guanine, one of the DNA molecule's four building blocks, with the others being adenine, cytosine, thymine. The structure comprises four guanines held together by a type of hydrogen bonding to form a sort of squarelike shape. (The DNA molecule is itself a double strand held together by these building blocks and wrapped together like a helix.) The new visualization of the G-quadruplex is detailed this week in the journal Nature Chemistry.
