New insights into how cellulose is built could indicate how to break it apart for biofuels
Using the model plant species Arabidopsis thaliana, also known as thale cress, a team of researchers from Penn State have identified the main proteins that prepare plants to create cellulose – a compound used in a variety of manmade materials.

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.
