Human hippocampus stained with a method pioneered by Italian physician Camillo Golgi in 1873.
Golgi discovered a chemical reaction that allowed him to examine nervous tissue in much greater detail than ever before. For some reason, hardening a piece of brain in potassium dichromate, and subsequently dousing it with silver nitrate, dyed only a few cell bodies and their respective projections in the tissue sample, revealing their complete structures and exact arrangement within the unstained tissue. If the reaction had stained all the neurons in a sample, Golgi would have been left with an unfathomable black blotch, as though someone had spilled a bottle of ink. Instead, his technique yielded neat black silhouettes against a translucent yellow background.More in Scientific American’s Know Your Neurons series.
nah, dude. you’re good.
Photographer: Wilson A. Bentley, published in the January 1923 National Geographic.
Wilson 19 years of age when he discovered a way to photograph snow After much experimentation Wilson created a technique technique using a bellows camera attached to a compound microscope.
Wilson was among the first photographers to photograph snow: of all the forms of water, the tiny six-pointed crystals of ice are incomparably the most beautiful and varied. We all know that each snowflake is different, but who would have known that geometrically and structurally snow varied as much as someones geometric art collection would.
The Banji, or Yangtze River Dolphin, is among the more rare animals of the world. The Banji is a freshwater dolphin that was declared “functionally extinct” in 2006. The animal only appears in the Yangtze River, and the industrialization of China has greatly damaged the Banji population. A man reportedly videotaped the dolphin in 2007, and scientists have tentatively validated that the animal in the video was the Banji. Despite the hope that this creature may still be living in the wild, the sighting of the dolphin does not mean the dolphin is successfully breeding. The population is clearly not high enough to retract the species status as “functionally extinct”.

Science: Molecular model of an antibody
This Y-shaped protein is produced by B-lymphocyte white blood cells as part of an immune response. The ‘limbs’ (upper left & right) bind to foreign antigens such as the surface proteins of invading bacteria, preventing them from interfering with normal cell processes. Bound antibodies can also make it easier for macrophage white blood cells to digest antigens, as well as triggering the breakdown of foreign cells by the complement system.
