Brain networks change according to cognitive task

... number of lanes. In the brain, there is a dynamic change that allows certain pathways to preferentially facilitate the demands of a given cognitive task. The brain highway in effect "adds lanes" to accommodate the requirements of the particular task. Depending on the goal of the task -- whether subjects w...

The making of a fat cell

..."Fat cells require contact in order to stretch and change shape--becoming round cells able to accumulate lots of lipids," said Saltiel. "Many things happen in the generation of fat cells, the transition from one integrin to another is a crucial step." While there is no evidence as yet to suggest that chang...

Scientists get first glimpse at how plants, most animals repair UV-damaged DNA

...nderstanding it. Zhong hopes his latest study will change that. "Maybe now that we know how light, enzyme, and water work together to control the timing, we can modulate this function and mimic what nature does," he said. "We want to understand why this timing is so perfect." Zhong conducted this study wi...
