UC Riverside scientists have discovered the potentially fatal liver fluke parasite, Heterobilharzia americana, in the Colorado River in California, a first for the region. Originating from research on local canine infections, the finding highlights the unexpected presence of parasite-carrying snails. Dog owners are urged to be cautious and watch for symptoms of infection. While the parasite can cause swimmer’s itch in humans, it poses no significant health risk and is unlikely to contaminate drinking water due to…

The transition in star formation rates and black hole growth as redshift decreases from regimes where positive feedback dominates to a later epoch when feedback is largely negative. CreditSteven Burrows, Rosemary Wyse, and Mitch BegelmanThe James Webb Space Telescope’s discovery of early galaxies with massive black holes challenges traditional galaxy formation theories, proposing a synchronous development of black holes and stars, a finding that could reshape our understanding of cosmic evolution.Astronomers have long…

That's because every one-year increase in guaranteed contract length for MLB players leads to increases in underperformance of about $1.6 million per year in 2010 dollars, a new University of…

Digital transformation and the market share–profitability relationship. Notes: H1 entails a negative moderation effect, i.e., the relationship between market share and profitability is weaker for more digital companies than for less digital companies. Thus, for H2-H5, a “+” means that this negative moderation effect of H1 becomes weaker, while a “–” means that it becomes stronger. Credit: International Journal of Research in Marketing (2024).

It is predicted to cause more extensive damage than the 2011 Great East Japan Earthquake and fatalities may exceed 320,000. It is believed that this megathrust earthquake will occur when the strain energy that…
