Read MoreBy Brittany Trinh (@brttnytrnh) Do you take your coffee with a spoonful of sugar or use a nonsugar sweetener such as Sweet’N Low or Equal? These nonsugar sweeteners are called nonnutritive sweeteners because they contain little to no calories per gram, compared with nutritive sweeteners such as sucrose or high-fructose corn syrup. Common nonnutritive sweeteners are saccharin and aspartame. Nonsugar sweeteners are often hundreds of times sweeter than sucrose—125 mg of aspartame can replace 25 g of sugar. They have been recommended by medical professionals as sugar substitutes in food…

In chemical terms, heavy metals are elements in earth’s crust that have a high density (weight), and they include zinc, copper, iron, silver, gold, arsenic, lead, and cobalt, to name a few. While trace amounts of heavy metals such as copper, iron, cobalt, and…
Read MoreBy Radhika Desikan Does age really matter? For us humans, age seems to be a very sensitive issue relevant to how we live our lives. And while it also matters to plants, it does so at a different level. Some of our tissues, like skin, have cells that are constantly dividing (to replace dead cells) and therefore differ in age, but what defines our age as an organism is not the life span of individual cells in our body, but rather the length of time that has passed since our…
