Starving tumors makes cancer treatment work better

Pancreatic cancer cells are known for being hard to treat, partly because they change the environment around them to block drugs and immune cells. Scientists discovered that these tumors use a scavenging process—called macropinocytosis—to pull nutrients from nearby tissue and keep growing. By blocking this process in mice, researchers were able to change the tumor’s environment, making it softer, less dense, and easier for immune cells and therapies to reach.

Perfectly timed cancer combo wipes out tumors by supercharging the immune system

Head and neck cancer, notoriously hard to treat, might have a new weakness—timing. Researchers discovered that syncing radiation and immunotherapy in just the right way can make tumors disappear in mice. By protecting the body’s immune system hubs, they’ve unlocked a potentially powerful method to fight aggressive cancers more effectively. Clinical trials are already underway, hinting at a new era in cancer treatment.

Breakthrough lung cancer treatment supercharges immune cells with mitochondria

Scientists have found a way to supercharge lung cancer treatment by transplanting healthy mitochondria into tumors, which both boosts immune response and makes chemotherapy far more effective. By combining this novel method with cisplatin, researchers reversed harmful tumor metabolism and empowered immune cells to fight back, all without added toxicity.

This vaccine uses dental floss instead of needles

Scientists have discovered that flossing between your teeth could one day help vaccinate you. By targeting a uniquely permeable gum tissue called the junctional epithelium, this new method stimulates immunity right where many infections enter: the mouth, nose, and lungs. Using dental floss on mice to apply a flu vaccine triggered a robust immune response—better than existing oral approaches and comparable to nasal vaccines, but without the risks. It even worked with mRNA and protein-based vaccines.
