The trick, then, is in getting the new gene into the bacteria. The easiest way is to splice the gene into aplasmid-- a small ring of DNA that bacteria often pass to one another in a primitive form of sex. Scientists have developed very precise tools for cutting standard plasmids and sp...
Scientists generally use a more sensible criteria these days, though it's based mostly on subjective assessment. If the volcano is erupting or demonstrating activity in the form of earthquakes or gaseous emissions, it is considered active. If the volcano is not showing any signs of activity, ...
Within the blood are also numerous molecules formed as byproducts of normal biochemical functions. When these molecules indicate how your cells areresponding to disease, injury or stress, scientists often refer to them asbiological markers, or biomarkers. Thus, biomarkers in a blood sample can repre...

In a different study, scientists found higher amounts of microscopic plastic particles in the feces of people with inflammatory bowel disease. While some recent studies are finding some associations between PFAS and microplastic exposure with serious medical conditions, Dr. Gerber says m...
This discovery was critical in helping scientists determine how leptin worked its magic in the ARC, the first stop in the hunger circuit. It turned out that when leptin reached the ARC, it set off a biochemical chain reaction that caused more melanocortin hormones to be released, eventually act...
Scientists will come to a complete understanding of DNA and show how mutations and natural selection explain every part of the development of life on this planet. Scientists will develop a new theory that answers the questions posed above to almost everyone's satisfaction, and it will replace the...
