Researchers report that DNA polymerase theta, or PolQ, promotes an inaccurate repair process, which can ultimately cause mutations, cell death or cancer.

As atmospheric carbon dioxide levels rise, so does the pressure on the plant kingdom. The hope among policymakers, scientists and concerned citizens is that plants will absorb some of the extra CO₂ and mitigate the impacts of climate change. For a few decades now, researchers have hypothesized about one major roadblock: nitrogen.

Malnutrition early in life appears to diminish brain function in older adulthood, according to a new study that has implications for many poor, developing nations.

Researchers have discovered a potentially important piece of the quantum/classical puzzle -- learning how the rules of physics in the quantum world (think smaller than microscopic) change when applied to the classical world (think every day items, like cars and trees).

A volcanologist has shown how the jet stream -- the area in the atmosphere that pilots prefer to fly in -- also seems to be the area most likely to be impacted by plumes from volcanic ash.
