It was just over two centuries ago that the global population was 1 billion - in 1804. But better medicine and improved agriculture resulted in higher life expectancy for children, dramatically increasing the world population.

Clouds, the most exciting spectacle after the Big Bang
The announcement of the discovery of two gas clouds that have formed in the first minutes after the Big Bang was published in Science; the clouds composition confirms theoretical predictions. The leading author of the study is the Italian Michele Fumagalli, from the University of California Santa Cruz, with whom we had a chat and to whom we asked for some clarifications.The discovery is the result of a clever observation technique and excellent performance of the spectrograph at the Hawaiian Observatory WM Keck.
600 Mysteries in the Night Sky
NASA
The Fermi Gamma-ray Space Telescope recently produced a map of the night sky. Out of 1873 new sources, nearly 600 were complete mysteries. In this week's ScienceCast, researchers speculate on the nature of the mystery objects - including the possibility that they are made of dark matter.

Composite image of brain MRIs
Brain's anatomical variations
Using computer software programs, scientists combined brain MRIs from 20 normal people into this composite image, in which ellipsoids represent normal anatomical variations. Pink purple ellipsoids, signifying the greatest variation, occur in brain regions that are uniquely human for example, regions that control language and logical reasoning.

20 Hz
Geo-magnetic storm
20 Hz observes a geo-magnetic storm occurring in the Earth's upper atmosphere. Working with data collected from the CARISMA radio array and interpreted as audio, we hear tweeting and rumbles caused by incoming solar wind, captured at the frequency of 20 Hertz. Generated directly by the sound, tangible and sculptural forms emerge suggestive of scientific visualisations. As different frequencies interact both visually and aurally, complex patterns emerge to create interference phenomena that probe the limits of our perception.
