You might have seen a great infographic popping up around the internet yesterday that showed the human body as a style of subway map (subway maps are becoming an increasingly popular metaphor for network visualization infographics). Most of the graphics were of disappointingly low resolution, but Sam has sent us an exclusive high-resolution copy of the graphic so that you can see all of the details and text.

Portuguese designer Susana Soares has developed a device for detecting cancer and other serious diseases using trained bees. The bees are placed in a glass chamber into which the patient exhales; the bees fly into a smaller secondary chamber if they detect cancer.
Scientists have found that honey bees - Apis mellifera - have an extraordinary sense of smell that is more acute than that of a sniffer dog and can detect airborne molecules in the parts-per-trillion range.
Bees can be trained to detect specific chemical odours, including the biomarkers associated with diseases such as tuberculosis, lung, skin and pancreatic cancer.
Insulin is produced by special cells called pancreatic islets (or islets of Langerhans), which exist as small, isolated clumps of cells within the pancreas. The islets of Langerhans also produce glucagon, another hormone which affects blood glucose levels. Both insulin and glucagon are secreted directly into your bloodstream, and work together to regulate the sugar (glucose) levels in your body.
Glucagon is produced by the alpha cells of the pancreatic islets. It is released when your blood sugar levels are low (for example, if you have been fasting or exercising) stimulating the release of glucose from your body stores. As a result, stored glycogen in the liver is broken down to glucose and enters the bloodstream.
Insulin, on the other hand, is produced by the beta cells of the pancreatic islets. It is released when you have just eaten a meal and the level of glucose in your bloodstream is high. Insulin works by stimulating the cells within your body to take up the glucose in your blood, either for immediate energy or for storing as glycogen in your liver and muscle cells.
