New estimates suggest Australia’s Indigenous population was much larger before European colonization and declined by roughly 93% between 1788 and 1861. European colonization of Australia began in 1788 with the arrival of Britain’s First Fleet. By the time early censuses counted Indigenous people, disease and violence had already devastated their communities, leaving those records an […]
A Cloudy Climate Mystery Over Antarctica Has Scientists Rethinking Their Models
Researchers compare observations with leading climate models to identify errors and help improve future climate predictions. Some simulations put too many low clouds over the Southern Ocean, yet still underestimate how much heat reaches the surface below. Observations from an Antarctic research voyage suggest that fixing the cloud count alone will not solve the problem. […]
A New Helium Measurement Is Testing the Universe’s First Five Minutes
Large Binocular Telescope data cut helium measurement uncertainty threefold. Helium, a light chemical element, carries clues to what the universe was like during its first five minutes. To read that record, an international team turned to 15 small, remote galaxies whose chemistry has changed very little, preserving a composition close to that of the early […]
