New crystal structures reveal a mysterious mechanism of gene regulation by the "magic spot"
In 1969, Cashel and Gallant identified a magic spot (MS) that appeared on a chromatogram (left) made from bacteria that had been starved a key nutrient. This magic spot was later identified as ppGpp and shown to influence the expression of over 500 genes in response to stress. An innovative crystallization technique now has allowed researchers to determine the structure of ppGpp in complex with bacterial RNA polymerase and DksA (upper right).

Big black holes outpace their galaxies in growth
An image from the Chandra Deep Field-South (blue, the deepest ever obtained in X-rays) combined with an optical and infrared image from the Hubble Space Telescope (HST; red, green, and blue). Each Chandra source is produced by hot gas falling towards a supermassive black hole in the center of the host galaxy, as depicted in the artist’s illustration.

Deep-sea fish use hydrothermal vents to incubate eggs
Eggs of deep-sea skates have been discovered near the hottest type of hydrothermal vents, where super-heated water emerges out of the sea floor. These vents, called black smokers, emit dark, sulphurous plumes. Credit: Ocean Exploration Trust
