Scientists have collected the most detailed recordings of narwhals to date, displaying a charming range of click, squeak, and buzz vocalisations that will help researchers understand these ‘sea unicorns’ like never before. This information could help scientists predict how the East Greenland narwhals might be affected by an increase in human-made sounds in their waters,

The most complete analysis to date measuring ice sheet changes in Antarctica reveals Earth’s southernmost continent has lost some 3 trillion tonnes of ice over the past quarter-century. A collective effort by over 80 scientists across the world used satellite data to determine estimates of ice-sheet mass balance between 1992 and 2017, ultimately calculating that

Particles collected from Earth’s upper atmosphere, originally deposited by comets, are older than our Solar System, scientists say – and these fine bits of interstellar dust could teach us about how planets and stars form from the very beginning. These cosmic particles have lived through at least 4.6 billion years and travelled across incredible distances,

The source of a mysterious microwave glow detected across our galaxy eluded astronomers for decades. But now a crack team has finally pinpointed the source: nanoscopic particles of crystalline carbon, otherwise known as diamond dust. There are several environments across the Milky Way that produce a faint glow known as anomalous microwave emission (AME). Scientists
