Scientists have long treated mass extinctions as events locked deep in the fossil record. That framing now feels less distant. New research points to patterns that resemble earlier biological ...

The wavelength-dependence can be plotted as an "extinction curve," and its shape provides information not only about the composition of the dust, but also about its local environment, such as the ...

Voluminous clouds of cosmic dust permeate our galaxy, but only recently has software allowed detailed observations of the stuff at scale. Reading time 2 minutes Astronomers at the Max Planck Institute ...

Red indicates regions where extinction falls off more rapidly at long wavelengths (the red end of the spectrum), while blue indicates that extinction is less dependent on wavelength. Regions with ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...
