Is It Possible To Have Excess Weight And Still Be Healthy?

by Jalees Rehman in The Next Regeneration

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 »

Scientific Approaches to Enriching the Lives of Sanctuary Wolves and Wolf-Dog “Hybrids”

by Cobb & Hecht in Do You Believe In Dog?

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 »

Emerging Influenza Viruses

by thelonevirologist in Virology Tidbits

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. Following the conformation of a human case of Influenza A H7N9 in January of this year -and subsequent culling of chicken in Hongkong and a ban of poultry exports-, the Financial Times reported the........

Stereotypical dogs: repetitive and pointless?

by Cobb & Hecht in Do You Believe In Dog?

"I'm a labrador" does not = "I'm hungry" (source)Hey Julie,it's great to get an updated view of what's on the canine science cards for you in 2014 - looks like we're both going to be keeping busy - and wouldn't have it any other way!I can't believe we're already into February, to be honest. There are so many great new publications coming out, it's quite exciting to be able to share them with you here!

EXPERIMENTAL TECHNIQUES EXPLAINED: THIN LAYER CHROMATOGRAPHY (TLC)

by Ryan Sweet in Antisense Science

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).

So far, good stuff! But! How does it work, and what the HELL do these results mean!?!... Read more »

"Lewontin's Fallacy" and Race

by Alexis Delanoir in How to Paint Your Panda

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 »

We Are Each A Community

by Miss Behavior in The Scorpion and the Frog

Lactobacillus (the purple rod-shaped things) is a common bacterial species in reproductive tracts. Image by Janice Carr from the CDC at Wikimedia Commons. In our world of antibacterial soaps, we have learned that bacteria are evil, dirty, sickness-causing agents to be eliminated at all costs. Although some bacteria can cause sickness, bacteria in general are actually a critical component of animal bodies. A human body has ten times as many bacterial cells as human cells and a hundred times........ Read more »

Nanoscale Engineering of Lithiated Nanowires for Battery Electrodes

by Jonathan Trinastic in Goodnight Earth

By coating germanium nanowires with a layer of silicon, Liu and colleagues show that lithium no longer wants to diffuse into the nanowire, known as lithiation, but rather creates a layer that grows along the axis of the nanowire. This could lead to a new architecture for battery electrodes and limit volume expansion.... Read more »
