New method identifies protein-protein interactions on basis of sequence alone (PNAS)

By Catherine Zandonella, Office of the Dean for Research Genomic sequencing has provided an enormous amount of new information, but researchers haven't always been able to use that data to understand living systems. Now a group of researchers has used mathematical analysis to figure out whether two proteins interact with each other, just by looking … Continue reading New method identifies protein-protein interactions on basis of sequence alone (PNAS)

Ice cores reveal a slow decline in atmospheric oxygen over the last 800,000 years (Science)

By Morgan Kelly, Office of Communications Princeton University researchers have compiled 30 years of data to construct the first ice core-based record of atmospheric oxygen concentrations spanning the past 800,000 years, according to a paper published today in the journal Science. The record shows that atmospheric oxygen has declined 0.7 percent relative to current atmospheric-oxygen … Continue reading Ice cores reveal a slow decline in atmospheric oxygen over the last 800,000 years (Science)
