Medical Xpress / Bacterial enzyme may cause fatal heart conditions with pneumonia infections

Pneumonia is a disease that burdens the health care system with more than 1.2 million emergency room visits each year and more than 41,000 adult deaths in the United States. Worldwide, more than one million children under ...

Phys.org / Camera traps snap nearly three times more images of endangered Sumatran tigers than before

Destroyed habitats, poaching, and prey depletion have dramatically reduced tiger habitats around the world. Today, tigers occupy just 5–10% of their historical habitats. But on the Indonesian island of Sumatra, an important ...
