Leaf-feeding caterpillars greatly enrich their intestinal flora by eating soil. It's even possible to trace the legacy effects of plants that previously grew in that soil through bacteria and fungi in the caterpillars.

The Italian Crested Newt eats anything and everything it can overpower. Earthworms, mosquito larvae and water fleas are on its menu, but also snails, small fish and even its own offspring. A research team has now studied the newt's chewing behavior and has made an astounding discovery.

In a surprising finding, researchers showed the protein NLRP6 aggravated the difficult symptoms of gastrointestinal graft-vs.-host disease. Knocking out this protein in mice led to significantly better survival and less severe GVHD.

Physicists developed a new mode of photoacoustic imaging called F-mode. This new mode selectively enhances photoacoustic image features based on the size of the object and the sounds it produces.

An OU-led project is showing how citizen science programs provide valuable data on rivers in southwestern United States. The ecological and hydrological data obtained from intermittent rivers (rivers that dry at some point in space or time) in Arizona are input into a nationwide network. Trained citizen scientists are mapping three rivers in Arizona: the San Pedro River, Cienega Creek and Agua Fria River.

More and more products carry ethical labels such as fair-trade or organic, which consumers view positively. Nevertheless, the sales figures of these products often remain low, even though they offer advantages for the environment or for society. A team of scientists have investigated what factors influence consumers' purchasing intentions.

Adopting stricter state gun laws is linked to a safer school experience for students, a new study has found. Strengthening gun laws at state level was associated with teens being less likely to report being threatened or injured with a weapon at school, miss at least one day of school due to feeling unsafe, or to carry a weapon at any location.
