In the past decade, scientists were baffled with the growing number of bacteria, which developed resistance to the common and sometimes high end antibiotics used to treat such infections. Although methicillin resistance among Staphylococcus aureus (MRSA) was first detected in the year 1961, there were...
What is an electrocardiogram (ECG)?
By: Quinn Decent
The heart rate is the number of beats per minute. On average, an adult human’s heart beats around 70-75 beats per minute. A precise way of measuring the heart rate is the electrocardiograph (EKG). EKG's can diagnose the condition of the heart by reading...

A new method has been developed that enables scientists to control specific events in targeted cells of living tissue. This emerging technology is known as optogenetics. The technology, chosen by the interdisciplinary research journal Nature Methods as the Method of the Year (MOTY) across all...
Optogenetics: Controlling brain circuits with light
By: Erin Yorke
Optogenetics is the science of controlling brain circuits with light. It is a field that shows great potential for brain study, and treatment of its disorders. This exciting study "...combines optical and genetic techniques". Its promise lies in being able to turn neurons on...

Optogenetics is a modern technology that enables researchers to precisely target and control specific events in biological systems, including freely-moving mammals. Gain or loss of function of well-defined biological activities in certain cells of living tissue is achieved by using a combination of genetic and...
