Canine Eyedrop Study

From Pets to People: Canine Eyedrop Study Offers Insights for Human Eye Care

22 May, 2025

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.

Bacterial Movement Fuels the Spread of Antibiotic Resistance

Spinning Into Resistance: The Flagella’s Hidden Role

22 May, 2025

A new study from the Hebrew University of Jerusalem reveals that bacterial movement plays a central role in the transfer of antibiotic resistance genes. The research team discovered that the rotation of flagella in Bacillus subtilis acts as a mechanical signal that activates key conjugation genes. This enables donor bacteria to form clusters with recipients and successfully transfer DNA in liquid environments. The findings suggest that bacteria can use motion to control when and where gene sharing occurs, offering new insight into the spread of resistance across species.

How the DNA’s Environment Shapes Smoking-Related Cancer Risk

13 February, 2025

Cigarette smoke causes cancer primarily by damaging the DNA. A new study that mapped the DNA damages caused by smoking, reveals that the way our DNA is organized and chemically modified can influence how cigarette smoke damages it, how well the damage is repaired and how many mutations will form. Specifically, areas of DNA that are more open and active are more prone to damage but also better at repairing themselves, which helps to prevent mutations.

The Balbiani Body: Cracking the Secret of Embryonic Beginnings

12 January, 2025

Researchers have uncovered how egg cells prepare for the creation of life. Their work reveals the secrets of the Balbiani body, a remarkable structure that organizes essential molecules to guide early embryonic development. Using zebrafish models and cutting-edge imaging, the team discovered how this structure transforms from liquid droplets into a stable core, laying the groundwork for life itself. This discovery sheds light on the extraordinary precision of nature’s reproductive process.
