A team of researchers has made a significant breakthrough that could save countless lives in emergencies involving severe blood loss. Their new treatment involves activating a protein called PKC-ε soon after intense bleeding occurs. In their studies, this approach tripled survival rates, increasing them from 25% to an impressive 73%. Additionally, the treatment helped maintain healthy organ function by boosting cellular energy levels, offering hope for improved outcomes in emergency trauma care.

Researchers have discovered that a key bacterial protein, CsrA, gathers in a droplet-like structure inside cells to control when and how bacteria activate their disease-causing genes. This newly identified compartment, which forms without a membrane, acts as a kind of temporary control center, helping bacteria adapt to their environment and switch between being harmless and virulent—offering new insight into how infections begin and how they might be stopped.

A new study shows that factual knowledge can reduce polarization on contentious topics. Participants who engaged with balanced facts about gun control shifted toward more moderate policy views—an effect that lasted even after a month. The findings suggest that, contrary to popular belief, people are open to learning facts that challenge their beliefs and that accurate information can promote a healthier discourse.

The Hebrew University of Jerusalem proudly congratulates Dr. Uria Alcolombri on being named one of the 19 Frontiers Planet Prize 2025 National Champions – and the only Israeli scientist to receive this honor in this year’s prestigious global competition.

New study sheds light on how insects, spiders, crustaceans, and other arthropods evolved their distinct body structures. By tracing these patterns back to ancient embryonic processes, the research uncovers a deep evolutionary logic behind the segmented body plans that define the world’s most diverse animal group. The findings challenge long-held assumptions and offer a bold new framework for understanding how developmental mechanisms shaped the evolution of arthropods over hundreds of millions of years.

A promising new discovery from the Hebrew University of Jerusalem reveals that cross-linked hyaluronic acid (XHA) significantly enhances the retention and concentration of topical antibiotics in the tear film of dogs. Compared to traditional formulations using polyvinyl alcohol (PVA), the XHA-based eyedrops maintained higher drug levels for longer durations. This innovation not only suggests improved treatment outcomes for veterinary patients – it also carries meaningful implications for human medicine.
