For the first time, astronomers peered to the edge of a massive black hole at the heart of a distant galaxy and measured its "point of no return." Shep Doeleman, assistant director at MIT's Haystack Observatory, shares some of the black hole's deepest (and darkest) secrets.
Reporting in Science, researchers write that mouse stem cells can be transformed not only into egg cells--but into newborn pups. Sean Morrison, a stem cell expert at the University of Texas Southwestern, explains the stem cell's journey, and what it could mean for fertility and assisted reproduction.
A recent study conducted at the University of Pennsylvania identified key molecules involved in forming long-term memories. Experts discuss how this is the latest in a growing field of research on how our bodies regulate our genes, and how this process affects our memories.
Over the past 27 years, Australia's Great Barrier Reef has lost half of its live coral cover, and a type of starfish is partly to blame for the alarming decline. Mark Eakin, head of NOAA's Coral Reef Watch program, discusses how to save the world's largest coral reef system.

Scientists in Japan report they have created eggs from stem cells in a mammal for the first time. And the researchers went on to breed healthy offspring from the eggs they created. While the experiments involved mice, the work is being met with excitement — and questions — about doing the same thing for humans someday.
