From there, they sneak past the protective barrier lining the respiratory system and head to the lymph nodes in search of cells that express a particular protein called signaling lymphocytic activation molecule, or SLAM.

White granulated sugar is composed of microscopic, crystalline sucrose molecules.

That would involve a process called "cracking" which breaks down the products into smaller molecules.

However, efforts are underway to test new small molecules in rodents that could improve resistance to radiation.

"What's really exciting about this, is it's a totally undiscovered process by which anti-germ molecules are made inside our cells, it feels profoundly important and surprising."
