The Black Death Plague Doctor: A plague doctor was a special medical physician who saw those who had the Bubonic Plague. In the seventeenth and eighteenth centuries, some doctors wore a beak-like mask which was filled with aromatic items. The masks were designed to protect them from putrid air, which (according to the miasmatic theory of disease) was seen as the cause of infection. The protective suit consisted of a heavy fabric overcoat that was waxed. A wooden cane pointer was used to hel...

Every moment your body is undergoing an active process of regeneration, based as it is on the ceaseless flux of cell life and death — not unlike the dissipative structure of a flame. Consider the fact that every two days the enterocytes lining your intestines are completely replaced, and that within 100 days, almost every atom and molecule within your body has been excreted, breathed out, or sloughed off, only to be replaced by new ones from the food you ate, the water you drank and the air...

Photograph courtesy Robert Rock Belliveau Magnified 800 times, the skin of a young cucumber Since fruits and vegetables are most vulnerable to predators when they're immature, cucumber plants have developed two "powerful mechanisms to protect themselves against most herbivores," photographer Robert Rock Belliveau, a retired pathologist, For one, young cucumbers grow sharp points on their trichomes (pictured), a type of plant appendage. These points are 40 times thinner than a sewing...

HUDSON RIVER DIATOM: Diatom species that have adapted to life in brackish water are common in tidal estuaries, where salty marine water mixes with the fresh waters brought down to the sea by rivers. Since the Hudson River is swept by marine tides up to 35 miles north of New York City, it is officially considered an estuary below that boundary. This brackish water diatom was found buried in Hudson sediments near West Point by Lamont marine geologist and Queens College (NY) professor Cecilia M...

Diatoms are one-celled marine and fresh water plants living inside siliceous shells that are constructed like little pill boxes with one half fitting into the other.

Diatom: At just first light in surge and drift, Within the darkling seas, In sheaves they swirled -- as winter mist Evaporates in the trees. I show you here one diatom. God's smallest lamp of glass and oil, Suspended in our ancient seas, Then frozen far beneath our soil. Beneath our star these diatomes, Misprisoned cells of oil in glass, In drifts descend into the sand, And melt to stone while eons pass. Within such stone they liquify, And flow in streams through granite ...

Making memories last Memories in our brains are maintained by connections between neurons called "synapses". But how do these synapses stay strong and keep memories alive for decades? Neuroscientists at the Stowers Institute for Medical Research have discovered a major clue from a study in fruit flies: Hardy, self-copying clusters or oligomers of a synapse protein are an essential ingredient for the formation of long-term memory. The finding supports a surprising new theory about memor...

Red Blood Cells Human blood with red blood cells, 3 T-lymphocytes, and activated platelets. Human red blood cells are the most abundant type of cell in human blood, accounting for 40% of the blood volume. Each cubic millimeter of blood contains around five million of these tiny, flexible disc-shaped cells. The red color comes from the iron-containing protein hemoglobin which picks up oxygen in the lungs and distributes it around the body. Because the cells have no nucleus and are subjecte...
