Manipulation of epigenome turns off as many genes as it turns on
...s -- are shut down because extra methyl groups are hanging on to them. If these extra methyl groups could be removed, the thinking has gone, the gene could be restarted and the cancer slowed or stopped. But the new work shows that while the agents tested do restart cancer-suppressing genes, they also knoc...Calorie restriction leads to some brain benefits but not others in mice

...an once in ape evolution.For example, climbing and hanging abilities are often thought t o have evolved together, but Pierolapithecus ' short fingers indicate that it didn't do a lot of hanging. Hanging-related traits may have evolved several times, showing up later in great apes, the researchers propose. ...Yellowstone microbes fueled by hydrogen, according to U. of Colorado study
...Spear collected samples of planktonic organisms by hanging a glass slide in the water and allowing the microbes to accumulate. "Bacteria are just like us. They like to be together, they like to be attached to a surface and they like to have their food - dissolved hydrogen, in this case -- brought to them."...Remote imagery aids in detecting and managing plant disease

The stark contrast between healthy cotton plants and the bare soil where the pathogen had killed the plants made the spots stand out in the photographs and the vertical angle allowed for comparative measures of...Researchers get first peek at amyloid's spine
...in forms the spine, and the rest of the protein is hanging out in globular domains that decorate the spine and give the fibril its thickness and bumpiness.
