Unravelling new complexity in the genome
...protein products by processing the RNA transcripts made
from genes (which are translated to make protein). We are finding that a significant number of genes operating in the same biological processes and pathways are regulated by alternative splicing differently in nervous system tissues compared to o...

some progress on the population ecology of mutualism, some of Holland's current work, which is slated for publication later this year, returns to his earlier interests in community ecology. "We want to understand how the structure of mutualistic comm...

MIT creates 3-D images of living cell
..., the slower the light travels. The researchers made
their measurements using a technique known as interferometry, in which a light wave passing through a cell is compared with a reference wave that doesn't pass through it. A 2D image containing information about refractive index is thus obtained. To...

by this gene appears to play a role in the accumulation of microfibullar deposits that causes XFG, providing a promising mechanism to target for developing therapy. We plan to conduct additional studies to examine how we can take advantage of this fi...
