Christmas is coming, and since a few of you have asked me where to get these i thought i would just put them all in one list, so;
- Aerogel - (currently out of stock, sorry.)
- Ecosphere - Comes in many different shapes; Large Sphere, Small Sphere, Small Pod/oval and more.
- Could not find a Gomboc, sorry.
- Gallium - 20 grams, 40 grams, 100 grams
- Miracle Berries - A lot cheaper than i thought they would be!
- Ferrofluid/Magnetic Fluid - heres a bonus gif :D
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.
Great little animation

30 years of Spacelab in picturesLaunched on 28 November 1983 aboard Space Shuttle Columbia, the European-built Spacelab was the first purpose-built space laboratory. Also onboard was Ulf Merbold, who became ESA’s first astronaut in space. Over the course of 30 years, Spacelab modules flew on the Space Shuttle 22 times and totalled 244 days in orbit.Click images for description
Making a Gem of a Tiny Crystal
Nature builds flawless diamonds, sapphires and other gems. Now a Northwestern University research team is the first to build near-perfect single crystals out of nanoparticles and DNA, using the same structure favored by nature.
“Single crystals are the backbone of many things we rely on — diamonds for beauty as well as industrial applications, sapphires for lasers and silicon for electronics,” said nanoscientist Chad A. Mirkin. “The precise placement of atoms within a well-defined lattice defines these high-quality crystals.
“Now we can do the same with nanomaterials and DNA, the blueprint of life,” Mirkin said. “Our method could lead to novel technologies and even enable new industries, much as the ability to grow silicon in perfect crystalline arrangements made possible the multibillion-dollar semiconductor industry.”
His research group developed the “recipe” for using nanomaterials as atoms, DNA as bonds and a little heat to form tiny crystals. This single-crystal recipe builds on superlattice techniques Mirkin’s lab has been developing for nearly two decades.
