A new way to compare human and other primate genomes

...- in order for mutations and the lack of selection pressures to cause the nonfunctional sequences in the two genomes to drift apart. For example, mice and humans last shared a common ancestor about 75 million years ago, plenty of time for the nonfunctional sequences in their respective genomes to go their sepa...

Expanding the genetic code: the worlds first truly unnatural organism

...racing the organisms -- exposing both to selective pressures at the same time and watching their development -- the researchers hope to see if the organism with the expanded genetic code has an evolutionary advantage over natural organisms. A number of scientists have previously added unnatural amino acids to ...

...mputations, which measured compressive and suction pressures on the residual limbs as they walked. Vacuum-assisted sockets drove less fluid out of the limb during stance (less compression) and drew more fluid in during swing (greater suction). Paper lends insight as to why the vacuum-assisted socket prevents t...

Effects of global warming already being felt on plants and animals worldwide

...ature rise in combination with other environmental pressures "could easily disrupt the connectedness among species" and possibly lead to numerous extinctions. Swallows, geraniums and spruce In their analysis, Root and her co-workers revealed that nearly 1,200 species - roughly 81 percent of the total number ...

Study offers a rare view of how species interactions evolve

...This kind of variation in coevolutionary selection pressures across a broad area may be an important factor shaping the genetic structure of species and the ecological dynamics of natural communities, Thompson said. "Ecologists have tended to study species interactions at the local level, but these results ar...
