Strange disease that causes fibers to grow underneath the skin
|
view preview
Imagine a disease whose presence is marked by a feeling of something crawling along your skin, stinging every part of your body as if there is insect or parasite infestation that doesn't go away. Not only that, but your skin is plagued with the presence of multicolored filaments that lie under, are embedded in, or project from skin. Morgellons disease (pronounced with either a hard or soft "g") is a highly misunderstood skin condition that was first reported in the USA in 2002, although may have a longer history depending on where you look. The characteristic filaments described earlier are microscopic, visually resembling textile fibers, and are white, black, or a more vibrant color, such as red or blue (left image). In addition to fiber p ...

Watch this 1940's Disney Cartoon Made to Fight Malaria
|
view preview
In 1943, Walt Disney helped combat malaria by making an animated film called The Winged Scourge. This short film starred the seven dwarfs and taught children that mosquitoes transmit malaria, which is a very bad disease. While not specifically mentioned in the film, malaria is caused by several species of the protozoan Plasmodium, of which Plasmodium vivax and Plasmodium falciparum are the most common. The most serious infections involve P. falciparum, which causes a higher incidence of complications and death. The short film advocated the killing of mosquitoes to stop the disease. Luckily, by 1951, malaria was finally eliminated in the United States ( eliminated means that no new cases arose in the country for 3 years). Today, oral chloroqui ...

A classic parasitic-host relationship
|
view preview
This lady beetle (Coccinellidae) is protecting its enemy. The cocoon between its legs holds a parasitoid wasp larva ( Dinocampus coccinellae), which fed on the beetle’s insides before bursting from its belly. Researchers have discovered what makes the beetles act as babysitters: They are infected with a brain-controlling virus. When the larva emerges and spins its cocoon, the virus makes the beetle freeze in place, protecting the baby wasp from predators. ...

Evolution is sneaky

While this little guy may look like some sort of 'Hummingbee' it's actually a Bee Fly. They sneak their eggs into beehives, where their larvae can parasitize bee larvae and eat their food reserves!

Parasitism at its worst
|
view preview
This image may look like something dreamed up for a surreal horror movie, but it's a real horror for the tarantula in question. This unfortunate arachnid is infected with Cordyceps, a parasitic fungus that replaces its host's tissue with its own. Cordyceps fungi invades its hosts (mainly arthropods), and its mycelium eventually replaces the host's tissue. Once the arthropod is dead, cylindrical or branching growths emerge from the creature's dead body. Some species also have mind-control capabilities, convincing the host to travel to a place where the fungus will find optimal growth conditions before the host dies." ...
