Nanotechnology Sensors for Non-Invasive Melanoma Scent Detection

A research team from The Wistar Institute and the University of Pennsylvania, led by scientists from the Monell Chemical Senses Center, has used a nanotechnology-based sensor to differentiate between the odors from normal skin cells and those that have melanoma. The initial findings of this team’s study indicate that this type of sensor could hold […]

A Simple Stroke of Genius

Polymerase Chain Reaction (PCR) may be a technical term and on the face of it sound like a subject you might not be familiar with. However, I’m sure everyone’s either watched CSI or a cheesy American-type chat show where several women go on the show to take a paternity test. Well, put simply, PCR is […]

Beautiful Nature: Bioluminescent Creatures

Bioluminescence is one of nature’s most incredible phenomena, and it can be found in an impressive diversity of organisms. It helps creatures ward off predators, attract mates, and lure in prey. Not to be confused with fluorescence or phosfluorescence, which involve absorbing and reflecting light, bioluminescence occurs as the result of a chemical reaction. Through […]

Stem Cells: The Basics

Most people have heard of stem cells and stem cell research and are aware of the controversy that surrounds this practice but the average layperson probably doesn’t completely understand what this subject is all about. A stem cell is, basically, a clear cell that has the ability to become another different cell type in the […]

Infographic: Watch Out for DNA Evidence
