Lake bottom testing shows plastics migrating down into sediment layers
A team of environmentalists, geographers and ecologists affiliated with several institutions in Europe has found that microplastics have migrated into multiple sediment layers in three lakes in Latvia. In their study, published ...
Using math to significantly improve modeling of surface and subsurface water flow in complex landscapes
Understanding how surface and subsurface waters are affected by drought, fire, warming, and increased human demand requires computer models that can represent complex environments. Predictions are especially difficult for ...

Low-density polyethylene microplastics partially alleviate toxicological effects induced by Cd exposure in earthworms
Cadmium (Cd) can accumulate in the food chain, with serious impacts on human health and safety. Microplastics (MPs) such as low density polyethylene (LDPE) should be considered not only as a single pollutant but also as a ...

History of abandoned urban sites found stored in soil
Old houses and vacant lots may not look like much to the naked eye, but to some, the site is better than gold. Excavations over the years can create a challenge to study what's left behind and often appears as if dirt and ...

New biomechanical method draws roots into deeper soil layers to resist drought stress
Tree roots are drawn towards moist soil, a phenomenon known as hydrotropism. Near surface watering therefore causes roots to stay close to the surface instead of growing deep into the ground. Biomechanical engineers from ...
