Gene regulation, not just genes, is what sets humans apart
...y sequences. The mouse genome had been used as a reference
point for comparing the coding sequences of humans and chimps, but the non-coding sequences have generally evolved much faster. Mice wouldnt work for analyzing the non-coding sequences, because theyre too different from humans and chimps, Haygood sai...
MIT creates 3-D images of living cell
...ght 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 create a 3D image, the researchers combined 100 two-dimensional images taken from different angles. The resulting images are essentiall...
