Zinc Oxide is a compound that may enhance immune function, especially when administered by inhalation.
Scientists are finding that particles that are barely there - tiny objects known as nanoparticles that have found a home in electronics, food containers, sunscreens, and a variety of applications - can breech our most personal protective barrier: The skin.
Cancer-sensing devices built as cheaply and efficiently as wristwatches - using many of the same operating principles - could change the way clinicians detect, treat and monitor cancer in patients.
Many people don't realize there's a difference between sunblock and sunscreen. True to its name, sunblock reflects the sun's rays, thereby blocking them from reaching your skin.
