Researchers at Shandong University have modified the probiotic bacterium Escherichia coli Nissle 1917 to produce the anticancer drug Romidepsin directly in tumors. In mouse models of breast cancer, the engineered bacteria accumulated in tumors and released the drug. The findings were published on March 17 in PLOS Biology.

Scientists have genetically modified Cutibacterium acnes, a common skin bacterium, to produce more heat and detect temperature changes. This could lead to a probiotic cream that wards off frostbite and hypothermia in extreme conditions. The research was presented at a conference in the UK.

Researchers at the University of Helsinki have found that mitochondria in plant cells can draw oxygen away from chloroplasts, revealing a new interaction that affects photosynthesis and stress responses. This discovery, published in Plant Physiology, explains how plants manage internal oxygen levels. The study used genetically modified Arabidopsis thaliana plants to observe these processes.

Researchers at Lund University in Sweden have created a cell-free cartilage scaffold that guides the body to repair damaged bone. The innovation, tested successfully in animal models, avoids strong immune reactions and offers a universal alternative to patient-specific grafts. Plans are underway to test it in human clinical trials.

A team led by Leonardo Ferreira at the Medical University of South Carolina is developing a novel therapy combining lab-made insulin-producing cells with engineered immune cells to protect them. Funded by $1 million from Breakthrough T1D, the approach aims to restore beta cell function without immunosuppressive drugs. This strategy builds on prior research and targets all stages of the disease.
