Genetically modified organisms (GMOs) are a broad group of plants, animals, and bacteria that are engineered for a wide variety of applications ranging from agricultural production to scientific research.
Titanium and titanium alloys are used in airplanes, missiles and rockets where strength, low weight and resistance to high temperatures are important. Since titanium does not react within the human body, it is used to create artificial hips, pins for setting bones and for other biological implants. Unfortunately, the high cost of titanium has limited its widespread use. Titanium oxide (TiO 2) is used as a pigment to create white paint and accounts for the largest use of the element. Pure titanium oxide is relatively clear and is used to create titania, an artificial gemstone.
To stay healthy, your body needs a daily dose of the right vitamins and certain minerals. One of those crucial minerals is zinc, which affects a variety of your physiological processes and body parts, including your skin [source: MedlinePlus]. Zinc is like a 24-hour, on-call skin mechanic. It helps repair damaged tissues and heal wounds. Without zinc, your body's inside and outside repair time -- and possible health costs -- go up. Like vitamins, minerals are essential to your overall health and development, helping the body grow and take care of itself.
