About 252 million years ago, volcanic eruptions triggered the End-Permian Mass Extinction, also known as the Great Dying. About 96 percent of marine species were wiped out—but were things just as grim on land?

Scientists have debated whether this event caused nearly as much terrestrial destruction. Now, researchers from the Nanjing Institute of Geology and Paleontology (NIGPAS) of the Chinese Academy of Sciences suggest that terrestrial ecosystems did not suffer nearly as much as the oceans.

Led by paleontologist Feng Liu, the NIGPAS team found evidence for refugiums, oases where life thrived despite the devastation. Not only did these refugiums give life a chance to survive the mass extinction event, which lasted 200,000 years, but they are now thought to have been crucial to rebuilding ecosystems in much less time than was previously assumed.

Optical illusions are great fun, and they fool virtually everyone. But have you ever wondered if you could train yourself to unsee these illusions? Our latest research suggests that you can.

Optical illusions tell a lot about how people see things. For example, look at the picture below.

The two orange circles are identical, but the one on the right looks bigger. Why? We use context to figure out what we are seeing. Something surrounded by smaller things is often quite big. Our visual system takes context into account, so it judges the orange circle on the right as bigger than the one on the left.
