AMPUTATION- *WARNING* GRAPHIC REENEACTMENT!

Not American Civil War related, but an excellent video to understand what exactly happened to American soldiers in the American Civil War

Military advances before and during the Civil War meant more powerful, destructive weapons, and more devastating injuries, including shattered bones. Most American doctors, however, were unprepared to treat such terrible wounds. Their experience mostly included pulling teeth and lancing boils. They did not recognize the need for cleanliness and sanitation. Little was known about bacteria and germs. For example, bandages were used over and over, and on different people, without being cleaned.

With so many patients, doctors did not have time to do tedious surgical repairs, and many wounds that could be treated easily today became very infected. So the army medics amputated lots of arms and legs, or limbs. About three-fourths of the operations performed during the war were amputations.

This film was created to show how battlefield surgery was performed between 1799 and 1815 during the time of the Napoleonic wars. The film was created by His Majesty’s 33rd Regiment of Foot First Yorkshire West Riding re-enactment group. www.33rdfoot.co.uk Filmed and edited by Martin Sunderland.

Tardigrades (Water Bears/Moss Piglets): 

These ambling, eight-legged microscopic “bears of the moss” are cute, ubiquitous, all but indestructible and a model organism for education

by William R. Miller

The young woman in my office doorway is inquiring about the summer internship I am offering. What’s a tardigrade? she asks…

Tardigrades, I reply, are microscopic, aquatic animals found just about everywhere on Earth. Terrestrial species live in the interior dampness of moss, lichen, leaf litter and soil; other species are found in fresh or salt water.

They are commonly known as water bears, a name derived from their resemblance to eight-legged pandas. Some call them moss piglets and they have also been compared to pygmy rhinoceroses and armadillos. On seeing them, most people say tardigrades are the cutest invertebrate.

At one time water bears were candidates to be the main model organism for studies of development. That role is now held most prominently by the roundworm Caenorhabditis elegans, the object of study for the many distinguished researchers following in the trail opened by Nobel Prize laureate Sydney Brenner, who began working on C. elegans in 1974. Water bears offer the same virtues that have made C. elegans so valuable for developmental studies: physiological simplicity, a fast breeding cycle and a precise, highly patterned development plan…
