A scientific expedition has discovered an uncharted island off the coast of Antarctica. The island is big enough to be visible by satellite but is covered in the remnants of the retreating ice sheet, making it hard to spot from space. As glaciers have retreated in West Antarctica, they have released pressure on Earth’s crust, allowing it to rebound and rise. Data from the new island could help researchers determine how fast the continent is lifting.

The push to decentralize Hungary’s cultural treasures has reached its 200-year-old natural-history museum. The government wants to move the museum’s rich collection from Budapest to the small town of Debrecen in the country’s east. Scientists have been campaigning against the move, citing the potential negative effects on research and the loss of experienced staff, most of whom have said they would not relocate.

The United Kingdom has another new science minister — a position that has seen a revolving door of appointments, firings and resignations in recent years. Non-scientist Amanda Solloway sits lower in the government hierarchy than previous science ministers and seems to have been handed a less-powerful version of the role. Some see the change as a sign that Prime Minister Boris Johnson and his influential adviser Dominic Cummings would prefer to guide science policy from the top.

Gabriel Waksman set up a native-tree-planting programme to offset the carbon emissions of travel associated with his career as a biologist. Academics, scientists and even people attending the same conference can contribute to themed groves in the highlands of Scotland. And, unlike with far-flung carbon-offset schemes, UK-based donors can choose to plant the trees and verify the benefits themselves.
