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 »

Medical Journal Apologizes “For The Distress Caused” By A Paper

by Neuroskeptic in Neuroskeptic_Discover

Anaesthesia and Intensive Care (AIC) is an Australian medical journal. The latest issue, just published online, contains a remarkable – and possibly even unique – pair of Letters. These letters take the form of apologies for the distress caused by the publication of an article – I do not know of any similar cases in […]The post Medical Journal Apologizes “For The Distress Caused” By A Paper appeared first on Neuroskeptic....

"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 »

The direction a dog’s tail wags says what it’s thinking

by Stuart Farrimond in Guru: Science Blog

In show business, they say that you should never work with animals or small children. The reasons are obvious: they are both unpredictable and you never know exactly what they are thinking. Children grow up and learn to communicate via […]The post The direction a dog’s tail wags says what it’s thinking appeared first on Guru Magazine.... Read more »

Exciting Science: Oncolytic Viruses (Review published in PLOS Pathogens)

by Kausik Datta in In Scientio Veritas

Science is awesome. But I expect you already knew that, dear readers o'mine. In science laboratories across the world, every day dedicated researchers are testing ideas, generating and evaluating hypotheses, critically analyzing observations, and thereby, making significant contribution to the humanity's attempts to understand in greater depth and detail the wonderful natural world that surrounds us, of which we, along with other living beings and non-living objects, form a part. Ho hum, you say........ 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 »

Why do women stop losing their hair when pregnant?

by Stuart Farrimond in Guru: Science Blog

Want thicker, shinier hair? Just try nature’s solution – get pregnant! During pregnancy, hair falls out less and many women say it looks incredible. The reason: hormones. When expecting, levels of the hormone oestrogen (US: estrogen) steadily increase. This, alongside […]The post Why do women stop losing their hair when pregnant? appeared first on Guru Magazine....

Why does so much research go unpublished?

by Dorothy Bishop in bishopblog

It's been estimated that as much as 85% of funded research is never published. Sometimes it doesn't get done because gremlins get in the way, but often completed research is still not written up. I discuss three reasons for this and suggest solutions that researchers, funders and journals could adopt.... Read more »

Lake Waiau

by Olga Vovk in Milchstraße

Lake Waiau at the top of Mauna Kea is shrinking. For some unknown reasons, for the last few years the lake has shrunk significantly and in September 2013 its diameter was only 15 m. In early 2010, the lake surface area began to shrink rapidly and, by late September 2013, had declined to just 115 m^2 (0.03 acres) – that is, about 2% of its normal surface area. ... Read more »

Freezing the Winter Away

by Miss Behavior in The Scorpion and the Frog

The clutches of the Polar Vortex are finally releasing its grasp on us and we can be thankful for our home heating, our layers of warm clothing, and most of all, our bodies’ abilities to generate heat. But it is times like these that make me wonder about our friends that live outside year-round… especially those that don’t generate most of their own body heat. How do they survive these periods of intense cold? There are several species of North American frogs that have an unusual trick up ........ Read more »

How You can Learn the Programming Basics in an Hour (Code Week 2013)

by Geoffrey Hannigan in Prophage

This probably would have best been posted a few days ago, but this week is computer science education week, or "code week" (coding just means writing computer programs). From December 9th to the 15th, over a million people all over the US are promoting computer science for students ranging from elementary school to college, as well as those of us finished with school. This is not only really cool because it is generating enthusiasm for computer science education, but it is also provi........ Read more »
