Genetic Diversity in Laboratory Rodent Colonies

GwynneL.

Inbred or Outbred? Genetic Diversity in Laboratory Rodent Colonies SUMMARY: This study looked at genetic diversity in lab gerbils. Due to the fact that labs are small, animal groups tend to become less diverse overtime; however, the overall diversity of the gerbils can be determined if you outbreed them. The significance of inbred or outbred… Continue reading Genetic Diversity in Laboratory Rodent Colonies

Dietary Fat Restriction Results in More Body Fat Loss than Carbohydrate Restriction

GwynneL.

Calorie for Calorie, Dietary Fat Restriction Results in More Body Fat Loss than Carbohydrate Restriction in People with Obesity SUMMARY: This small study looked at 19 people on either a low-carbohydrate diet or low-fat diet. The aim of the study was to see which diet reduced more body fat. The results showed that low-fat diets… Continue reading Dietary Fat Restriction Results in More Body Fat Loss than Carbohydrate Restriction

Why Is Pluto Red Part 2

GwynneL.

Ice Chemistry on Outer Solar System Bodies: Electron Radiolysis of N2-, CH4-, and Co-Containing Ices SUMMARY: In “Why Is Pluto Red Part 1” scientists beamed gases with UV photons; in this sequel, scientists beamed the same ratio of gases (nitrogen, methane, and carbon dioxide at a ratio of 100:1:1) with electrons. It’s thought that because… Continue reading Why Is Pluto Red Part 2
