Top 7 From F1000
1. How fat causes diabetes» There are new molecular links between obesity and diabetes—a high-fat diet in mice activates proteins associated with obesity, but these changes can be reversed by a well-known diabetes drug, suggesting the same pathway may also cause insulin-resistance.
2. A new metabolism » A novel metabolic pathway in the malaria parasite differs significantly from the classic Krebs cycle taught in textbooks, providing evidence that carbon metabolism can evolve.
3. Double-edged gene » Two gene variants found commonly in African genomes, which appear to explain why...
4. Focal structure » For the first time, researchers have described the three-dimensional molecular structure of focal adhesions, providing insights into how they secure cells to the extracellular matrix and participate in mechanosensory events.
5. How neurons grow » There’s another layer of complexity in the developing nervous system: Spontaneous neuronal activity can regulate the differentiation of neurons, affecting swimming behavior in frog larvae.
6. Retinal roles » Photosensitive ganglion cells, which were only discovered in the mammalian retina in the early 1990s, play a greater role in visual function than previously believed.
7. How cilia talk » Primary (nonmotile) cilia need membrane proteins to send and receive extracellular signals as part of their role as a coordinator of signaling pathways, and new findings show how cilia retain those membrane proteins—a barrier at the base of cilia made up of proteins called septins.
