In “Blood of the Tiger,” author J.A. Mills examines the multi-billion dollar market for tigers — a worldwide problem but most prominent in China. Jeffrey Brown interviews the author about how tiger farms drive mass demand for products made from tigers, and how that in turn spurs demand for wild animals via illegal hunting. Continue reading
Your genome contains thousands of genes, possible instructions that build your cells. So how do cells know which genes to use? A set of markers called the epigenome tells them which genes to turn on and off. But if they get it wrong, you could develop diseases like Alzheimer’s, Type-1 diabetes, cancer or multiple sclerosis.

A remote island in the Bahamas is home to dozens of species of native and migratory birds, including one that has been on the endangered species list for decades.

The NewsHour’s Cat Wise follows a group of researchers as they track and study the piping plover in its winter habitat. Continue reading
PBS NewsHour traveled to the Bahamas recently with a group of scientists to study an endangered shorebird bird called the piping plover. The birds have been on the endangered species list in the United States since the late 1980s, but like many species of migrating birds, scientists didn’t know much about their wintering grounds.
