Chromatography utilizes a mobile phase and a stationary phase that can be modified for each circumstance. The stationary phase is an absorbent material, such as silica that is coated on a surface such as glass or plastic. The mobile phase is a solvent, or mixture of solvents, t...
How do you use a spectrophotometer? Why is 70%-75% ethanol used for sterilization? Why do we use ray diagrams in optics? Why do scientists use microscopes? Why is vortexing used in laboratories? Why don't we use PT to measure heparin? Why are Bunsen burners not used in labs? Explain ...
Proteins are the functional agents that make biology go, and they are also functional tools that scientists need to do biological research. In a way, this is analogous to "compil- ing" a software program. The important difference to software, however, is that once "compiled," proteins are ...
As the broader community has become more exposed to the capabilities of remote sensing through easily accessible software, field scientists are looking to satellites to solve the issues with scope and spatial variability that we encounter in the field of water quality monitoring. >>>Sign up for a...

Beverage intake was collected using 24-hour dietary recalls or questionnaires. Scientists counted the number of servings of these bitter and sweet beverages consumed by about 336,000 individuals in the UK Biobank. Then they did a genome-wide association study of bitter beverage consumption and of ...
One of the CDC's own vaccine scientists -- a man who received millions of dollars in grant money from the CDC -- was recently indicted by a federal grand jury for money laundering and fraud (https://www.naturalnews.com/032216_Thorsen_fr...). Check out the NaturalNews diagram called ...
PRO:Outsourced asset management offers pharmas additional management resources and engineering expertise. It’s also liberating. Scientists are unshackled to focus on science rather than on the administration of capital resources. Procurement people no longer have to wrestle with multiple vendors and the...
A "bitter sweet" reaction That said, they're not perfect. While the primary sensation is sweet, saccharin and cyclamate can also trigger the tongue's bitter receptors which creates an unpleasant aftertaste. In the 1950s scientists realised that combining the two helped to mitigate this unwanted ...
Why do some scientists prefer to express concentrations of water contaminants in units of ppm and ppb rather than molarity?Water Contaminants:Water contaminants are substances that make water undrinkable and even dangerous to drink. They may be living or...
