Cancer scientists call for a large-scale human epigenome project
...microarray "chips." Modifications of DNA are also tracked on chips, following treatment with enzymes that recognize sites of methylation. Impressive accounts of success with these methods were presented at the workshop. These accounts included a report from the European Epigenome Project, headquartered at...Breaking the mold: Research teams sequence three fungus genomes
...g ambient temperatures in the lab, TIGR scientists tracked gene activity, documenting different A. fumigatus genes that turned on and off, as the environment warmed. The A. fumigatus genome is 28 Mb in size, consisting of 8 chromosomes bearing a total of almost 10,000 genes.

...n in just one night. "The first solitary coyote we tracked covered five adjacent cities in a single night," Gehrt said. Urban coyotes survive far longer than their rural cousins. A coyote living in urban Chicago has a 60-percent chance of surviving for one year, while a rural coyote has a 30 percent chance o...Rockefeller researchers discover a biological clock within a clock
.... For the first time, Period and Timeless could be tracked within a cell for eight hours or longer. "No one had ever labeled the components to follow them over time, to see one clock as it ticks away in a single cell," Young says. "All the biochemistry and molecular biology that had been done on this had bee...New Zealand tops environmental scorecard at World Economic Forum in Davos

Then the researchers applied their findings and additional data to an estimate of global demand for copper and other metals if all nations were fully developed and used modern tech...Hot-spring bacteria flip a metabolic switch
... tasks." Lead author Steunou and her collaborators tracked the activity of genes involved in photosynthesis and N2 fixation over a 24-hour period. They found that photosynthetic genes shut down shortly after nightfall, and N2-fixation genes switch on shortly thereafter.

... a biologist at UCSD and lead author of the study, tracked the ways that two active anthrax toxins, known as lethal factor, or LF, and edema factor, EF, cause cellular damage and death in the fruit fly Drosophila melanogaster. These toxins are required for the anthrax bacterium Bacillus anthracis to evade t...Contagious obesity? Identifying the human adenoviruses that may make us fat
