Hunters help safeguard Arizona's deer and elk from chronic wasting disease

Tuberculosis is still a rampant problem in the developing world. Doctors are looking for even more advanced ways to test for TB beyond the GeneXpert tests.

Washing hands in between contact with patients is one of the most important things a healthcare worker can do to prevent the spread of disease and reduce the rise of superbugs like MRSA. A new technology is increasing rates of hand washing by displaying, via a sensor in an employee's badge, whether the healthcare provider has washed their hands recently.

Wolves in western America were once hunted to near-extinction but have now been reintroduced into certain territories with notable success. More wolves often means more attacks on ranchers' livestock, however, so cowboys are working to track wolf packs by computer to reduce conflicts.

Clean water and healthy ecosystems are becoming increasingly difficult to come by. With floating islands and other inventions, eco-entrepreneur Bruce Kania thinks that biomimicry - such as reconstructing wetlands and growing biofilms - can tackle the toughest of water problems.

Concerned with colony collapse syndrome in honey bees worldwide, scientists, farmers and tech companies teamed up in Australia to create a micro-sensor that collects data on the bee's environment.

Slow test results make it difficult to stop the spread of tuberculosis. Using faster diagnostic technology and driving vans to rural areas in Tanzania, GeneXpert is making progress in treating this curable disease.

The World Conservation Union estimates that 40 percent of the more than 40,000 species it tracks on its Red List are close to extinction and this problem requires humans to change their behavior to fix it. Rare’s the Pride Campaign uses social marketing to attract attention and communicate the conservation message between local communities and government entities. The Pride Campaign has been replicated around the world for different conservation efforts to protect biodiversity.

A robust population of grizzly bears can be an indicator of healthy land; however, the bears also can destroy grain bins, consume vegetation, and kill livestock. Ranchers work with the Canadian government and local conservation groups to protect their resources with bear-proof grain bins and electric fences.

Despite significant increases in funding and advances in biomedical research, the rates of new treatments and drugs for illnesses that reach the market every year have plummeted. A group called the Myelin Repair Foundation, along with several other foundations, uses an intensely goal-directed and collaborative method to tackle the bottleneck.

India has, for years, been a hotbed of polio. Supported by the WHO as well as local health-care workers, immunizations have officially rid the country of the disease. There are still challenges in maintaining records and reaching everyone, but the message continously changes and adapts.
