| Mimicking living cells: Synthesizing ribosomes Posted: 29 Jun 2013 01:47 PM PDT Synthetic biology researchers have for the first time synthesized ribosomes from scratch in a test tube. The researchers took an approach different from their predecessors: they mimicked the natural synthesis of a ribosome, allowing natural enzymes of a cell to help facilitate the human-made construction. The technology could lead to the discovery of new antibiotics targeting ribosome assembly and the creation of tailor-made ribosomes to produce new proteins with exotic functions. |
| Survival of the Galapagos sea lion Posted: 29 Jun 2013 01:47 PM PDT The study shows that Galapagos sea lions (Zalophus wollebaeki) are more prone to starvation because of exposure to human influences like pets and pollution. These can impair the level of their immunity, making them less able to hunt and more likely to go hungry when food is scarce. |
