| Unpicking HIV's 'invisibility cloak' Posted: 10 Feb 2012 07:47 AM PST Drug researchers hunting for alternative ways to treat human immunodeficiency virus (HIV) infections may soon have a novel target -- its camouflage coat. HIV hides inside a cloak unusually rich in a sugar called mannose, which it uses to slip past the immune system before infecting its host's cells. Recently, however, biochemists discovered a family of chemical compounds that stick strongly to mannose. Understanding how this mechanism works could reveal a way to make drugs adhere to and kill HIV.  |
| Ultraviolet protection molecule in plants yields its secrets Posted: 09 Feb 2012 02:28 PM PST Lying around in the sun all day is hazardous not just for humans but also for plants. Ultraviolet radiation from the sun can damage proteins and DNA inside cells, leading to poor growth and even death. But plants have evolved some powerful adaptive defenses, including a complex array of protective responses orchestrated by a UV-sensing protein molecule known as UVR8. Now, scientists have put together a detailed picture of UVR8's structure and inner workings.  |
