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.

A strategy for stopping widespread depression in developing countries should be as obvious as one for combatting epidemics. A new strategy aims to downshift jobs to local workers to act as peer therapists.

Child mortality rates are decreasing in Afghanistan due to more readily available basic health care, more effective vaccinations, and locally-trained volunteer health workers.

Child mortality rates in third-world countries are often shockingly high. But they are gradually decreasing due to efforts that target contagious diseases and more widespread health education.

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.

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.
