Doping is the use of performance enhancing drugs or methods by athletes to gain a competitive advantage. Blood oxygenation enhancement is a type of doping that artificially increases an individual's hemoglobin concentration above normally occurring levels. Two common methods of blood doping are blood transfusion, or the transfer of blood into a person's vein, and [...]
As museum-goers, we often assume that artwork looks just as the artist intended it to look. This is generally not the case, as the passage of time necessarily degrades art, often in the form of dirt or cracks. The use of two technologies, laser ablation and bacteria, is helping to restore artwork to its intended [...]
