Przewalski’s horse, a species of wild horse that has been successfully reintroduced to the Gobi Desert, shares its pasture grounds with wild asses and free-roaming domestic horses. A scarce supply of food could lead to food competition among the different species, especially if they make the same dietary choices. A team led by researchers therefore chemically analyzed the tail hairs of the animals to determine the seasonal dietary habits of the three species.

Venezuelan equine encephalitis virus (VEEV) is an unforgiving killer of horses, donkeys and zebras, resulting in mortality as high as 80 percent of infected animals. It causes rapid, catastrophic swelling of the brain and spinal cord, leading to severe neurological symptoms and—in many cases—sudden death. The virus can also infect humans, with similar results. Now a research team has exploited a weakness in VEEV's genetic code, resulting in a far less deadly mutant version of the virus when tested in laboratory mice.
Incentives that are designed to enable smarter use of the ocean while also protecting marine ecosystems can and do work, and offer significant hope to help address the multiple environmental threats facing the world’s oceans, researchers conclude in a new analysis.
