Meet the Very First Mars Rover 

Long before the Sky Crane lowered Curiosity into Gale Crater, before the twin MER rovers Spirit and Opportunity bounced across the Martian surface, even before Sojourner was a glimmer in its designers’ eyes the Soviet Union launched the twin Prop-M rovers. Though neither rover made it to the surface, the technology stands as a brilliant example of the Soviet ingenuity that gave the nation an early lead in space.

Fight your Fear with Five Shark Facts:
1: Approximately 3.17 sharks are killed by humans every second while only less than 6 humans are killed by sharks every year. 
2: Sharks are relatively high in the food chain and keep populations of prey in check. 
3: Sharks have roamed the ocean for almost 400 million years, even before the dinosaurs. 
4: Your chances of encountering a Shark is very rare. You are more likely to get struck with lightning than to encounter a Shark.
5: Sharks are a slow growing species that don’t breed often. They are vulnerable to extinction.
Sharks have a bad rep above the ocean. Their creepy grins, appetite for meat and sharp teeth make it hard to appreciate them. While it may seem like they are out to get us, sharks are a magnificent species that need to be protected.

Clinical shot of patient recovering from gas gangrene
Gas gangrene is usually caused by the anaerobic bacteria Clostridium perfringens, but can be caused by any other anaerobic bacteria that infects muscle tissue. It’s often fatal, as the infection and exotoxins from the bacteria quickly flood the bloodstream, in addition to breaking down the muscular tissue.
If amputation was not an option, debridement (the medical removal of dead or infected tissue) and excision was often the only treatment. Secondary infection after removal of the infected tissue was a common problem, but antibiotic use after treatment helped stave off new bacteria.

The bat-eared fox is named for its huge ears, which can grow to be more than five inches long and stand out much like the ears on a bat. These foxes live in family units and typically eat insects to survive. 
This amazing animal can eat more than a million termites per year and can actually help control the termite population. They rarely drink water because they are able to hydrate with all the bugs they eat.
