Invasive grass in Texas uses chemical warfare to crowd out native species

Guinea grass, an invasive species in Texas, uses a combination of crowding and chemical toxins to suppress native plants. The researchers found that the toxicity of guinea grass increases dramatically when its shading effect is combined with its chemical warfare, making it harder for native plants to survive.

Positive emotion drives disinformation ads on Facebook

Research by University of Florida researchers found that disinformation ads on Facebook use a clear recipe with short ad buys, familiar language, and big budgets to reach more people. The most engaging ads were full of positive feelings encouraging good emotions about one's own groups rather than bad emotions towards others.

New models accurately simulate the behavior of sea ice

Researchers have developed a new sea ice model that can analyze the size and thickness of individual ice floes and their motion in greater detail. This allows for more precise predictions about their behavior, especially in areas where climate change has led to an increase in loose sea ice.

Knots smaller than human hair make materials unusually tough

Engineers at Caltech develop new material made from interconnected microscale knots, which absorb more energy and deform more while maintaining their original shape.
