Sewing just got scientific. Buckle up.
Gene SOE is a laboratory technique used to ‘stitch’ two pieces of DNA together; why is it spelt ‘SOE’ I hear you cry? That can be your homework. It’s a mystery to me. What I do know is that this technique has been around since the 80’s and is useful for deleting/fusing two DNA fragments together to produce truncated (that means ‘shortened’) proteins and/or two proteins fused together. That’s all very n........ Read more »

Is it possible to be overweight or obese and still be considered healthy? Most physicians advise their patients who are overweight or obese to lose weight because excess weight is a known risk factor for severe chronic diseases such as diabetes, high blood pressure or cardiovascular disease. However, in recent years, a controversy has arisen regarding the actual impact of increased weight on an individual’s life expectancy or risk of suffering from heart attacks. Some researchers argue tha........ Read more »

Hi Julie and Mia, I wanted to update you on some unique but exciting research that I conducted while working toward my Ph.D. at the University of Florida’s Canine Cognition and Behavior Lab. This particular research focuses on the welfare of wolves and wolf-dog “hybrids” in private sanctuaries.The common use of the term “hybrid” is perhaps the first indication of how poorly we understand these animals. The term “hybrid” is technically inaccurate – as wolves and domestic dogs are ........ Read more »

Frequently media outlets are reporting the identification of a novel strain of Influenza and in recents years this includes the identification of novel strains of avian influenza. More often than not, novel strains are identified because they have shown to cause severe disease in humans infected.

Thin layer chromatography, or TLC, is a technique used for the separation and analysis of molecules in a sample (Note- NOT DNA!). It can be used on amino acids1, although in my lab it has been used to analyze the degradation (or lack of!) of large polymeric sugars by whole metabolically inactivated cells or by simple enzymes. Because of this, I’ll be focusing on the analysis of saccharides (sugars).

Race is a hotly debated topic in both the sciences and politics. One contended issue is whether or not race, as a human classification, exists at a biological level. Richard Lewontin in 1972 argued that it is not so, but one famous paper by AWF Edwards contested his conclusions. So was Lewontin right? This post examines the arguments on both sides and comes to the conclusion, in the author's opinion, that race is not a valuable taxonomy for humans.... Read more »
