Biologists believed that urchin reproduction along the Pacific Coast would only be affected by marine heat waves at lethal ocean temperatures, a new study conducted by IB Assistant Professor Daniel Okamoto and other marine biologists at UC Berkeley suggests that this threshold of susceptibility, for urchins and other marine species, may be at lower temperatures than previously thought.

Electrostatics effects of jumping nematodes

Fri, 10/24/2025 - 15:48
Flows of tracer particles show the attractive force of a positively charged fruit fly. Parasitic nematodes use this static charge to leap onto the insects. Victor Ortega Jimenez/University of California, Berkeley

Assistant Professor Victor Ortega-Jiménez and his lab have discovered that jumping entomopathogenic nematodes can be electrostatically attracted by the natural electric fields of the flying insects, thus increasing the effectiveness attachment to distant hosts and likelihood of infection.
