How do the differing stances of the WA and SA governments on World Heritage listing for the Nullarbor Plain influence the current controversy?

The decision to exclude heritage assessments contradicts previous reports identifying the Nullarbor's world heritage significance and raises concerns about Australia's compliance with the World Heritage Convention. The lack of comprehensive assessment contrasts sharply with the WA government's past opposition to World Heritage listing and the SA government's recent commitment to securing such protection for its section of the Nullarbor. A petition with over 22,000 signatures opposes the project's location.

How did Fijian iguanas, geographically isolated in the South Pacific, originate from North America?

A new study suggests that Fijian iguanas, most closely related to North American desert iguanas, likely reached Fiji millions of years ago by floating on vegetation rafts across 8,000 kilometers of ocean. This journey, a record for land vertebrates, is supported by genetic analysis and a statistical model.

What is the significance of discovering four sub-Earth exoplanets orbiting Barnard's Star, the closest single star system to our solar system?

Astronomers using the MAROON-X instrument on the Gemini North telescope and ESPRESSO on the Very Large Telescope have found strong evidence of four sub-Earth exoplanets orbiting Barnard's Star, the nearest single star system to Earth. These planets are significantly smaller than Earth, ranging from 19% to 34% of Earth's mass, and orbit very closely to their star, resulting in surface temperatures too hot to support life. This discovery was published March 11 in The Astrophysical Journal Letters.
