Scientists have now completed the first global study of changes that occurred in a crucial component of ocean chemistry, the nitrogen cycle, at the end of the last ice age. Th...
Researchers have uncovered a previously unknown surveillance mechanism, known as a DNA damage checkpoint, used by cells to monitor oxidatively damaged DNA. DNA repair takes pl...
Biologists have performed a molecular level analysis of desert biological soil crusts -- living ground cover formed by microbial communities -- to reveal how long-dormant cyanobacteria become activated by rainfall then resume dormancy when the precipitation stops.
Scientists have developed a novel transgenic system which allows them to remotely activate individual brain cells in the model organism Drosophila using ambient temperature. T...
As spring warms up Wisconsin, humans aren't the only ones tending their gardens. Colonies of leaf-cutter ants cultivate thriving communities of fungi and bacteria using freshly cut plant material.
By midcentury, snowfall on Los Angeles–area mountains will be 30 to 40 percent less than it was at the end of the 20th century, according to a new study.
