This strange disease turns one's skin into bone
|
view preview
Known an fibrodysplasia ossificans progressive, or FOB for short, this disease can suddenly turn a person’s tissues and muscles into bone, thereby permanently immobilizing parts of the bodies. Joints such as elbows or ankles may become frozen in place; jaw motion can be impeded and the rib cage fixed, making eating or even breathing difficult. Currently, no cure exists to combat this rare condition.

Brain defects go a long way
|
view preview
This is a human brain without grooves and folds, a condition known as lissencephaly. It belonged to a patient who died in a mental health facility in 1970, and almost a year ago a photographer found the jar containing the brain in a collection at the University of Texas, Austin. People with this rare condition suffer from seizures, muscle spasms, a range of learning difficulties, and usually die before the age of ten. ...

Vulnerability to tuberculosis
|
view preview
If you’re not already acquainted, meet Mycobacterium tuberculosis – a wildly successful bacterium that has marched in lockstep with our population growth and history. The cause of tuberculosis, this bacterium is said to infect a new host every single second. Research lead Caitlin Pepperell from University of Wisconsin-Madison remarked, "Evolutionary theory predicts that M. tuberculosis populations should be vulnerable to extinction. Yet it is obviously highly prevalent. It must have some incredibly clever strategies and tricks to hang on." A paper published last month in PLoS Pathogens investigated 63 genomes from the bacteria and related pathogenic mycobacteria to gain insight into how natural election pressures have shaped its evolution and ...

Pellagra
|
view preview
In the early 1900s, the disease pellagra was widespread in the United States, especially in southern states. Individuals with pellagra were weak, and they developed diarrhea, a skin rash, and mental confusion. Each year, thousands of Americans died from this dreaded illness. In 1914 the U.S. surgeon general assigned Joseph Goldberger, a physician who worked in a federal government laboratory, to study pellagra. Most medical experts thought pellagra was an infectious disease because it often occurred where people lived in close quarters, such as prisons, orphanages, and mental health institutions. Goldberger knew from his previous research that infectious diseases usually spread through a population by close physical contact. While investiga ...
