A study by University of Cincinnati professor Jeremy Koster found that NBA stars on losing teams are less likely to follow teammates on Twitter compared to those on winning teams. This suggests that elite performers may distance themselves from their teammates in an attempt to escape responsibility for poor performance.
Researchers identify best irrigation methods for cotton in water-limited situations, challenging common assumption that producers should irrigate early and often. By reducing watering after plant emergence, yields and fiber quality can be maintained or even improved.
A new study by UC Santa Barbara community ecologist Keenan Stears examines how hippos shape the ecology of freshwater ecosystems. The research found that high-density hippo pools with excess nutrients cause dissolved oxygen levels to decline, leading to a decline in fish diversity and abundance.
