Scientists have developed a strategy to boost the cancer-fighting power of natural killer (NK) cells, part of the immune system’s first line of defence. NK cells can detect and destroy cancer cells, but tumours often create a protective barrier that blocks them, allowing cancer to grow.

Researchers at McGill University’s Rosalind & Morris Goodman Cancer Institute, in collaboration with the Research Institute of the McGill University Health Centre, found that suppressing two specific proteins helps NK cells overcome this blockage, turning them into more potent cancer killers.

By preserving tissue in its natural state, the technique reveals disease mechanisms that conventional methods can miss and helps identify more precise therapeutic targets.

Watkins-Conti Products, Inc. ("Watkins-Conti"), a company that develops innovative solutions for women's pelvic health, today announced the Company has added a second indication for its flagship product, the Yōni.Fit Bladder Support ("Yōni.Fit").

Antibiotic resistance is worsening worldwide, and plasmid conjugation is a major way resistance genes spread. A new study in Engineering finds that cinnamic acid, a safe, common food additive, can block this transfer process. It works by disrupting bacterial energy metabolism and reducing ATP supply. Tests in lab conditions, gut bacteria, and mice all show positive effects without harming health or gut flora, offering a promising natural way to fight drug-resistant infections.
