Dear Science, Stop Cheating Already

by Psych Your Mind in Psych Your Mind

Last night I was eating dinner at Rubio's (side note: "Baja Fresh," Rubio's slogan is a little confusing considering that their fish tacos are made with Alaskan pollock, just an observation) while surfing the web using my smartphone. What I found was shocking: an article released by the Science Magazine, states that dutch social psychologist Diedrik Stapel has "admitted to using faked data" and "will not be asked to return" to Tilburg University where he is........

Determining Labor Division in the Dead

by Katy Meyers Emery in Bones Don't Lie

Division of labor is a major part of understanding gender and class roles in historic populations. Without text, archaeologists depend on material and human remains for the answers. The physical stress (or lack thereof) from daily activities can leave markers … Continue reading →... Read more »

The Things They Carried: Former POWs, the Burma Railway & Threadworm

by Rebecca Kreston in BODY HORRORS

In February 1942, the city of Singapore was lost to the Japanese army during the Malaya campaign of World War II. The Fall of Singapore is considered to be one of the greatest British military disasters, with over 100,000 Allied troops consisting of British, Australian, American and Dutch soldiers captured. Several thousands of these men were sent to the Thai-Burma border to finish construction of the Burma Railway, known as the "Death Railway". Several medical surveys of these former ........

Can We Simplify Triage by Using Just GCS

by Rogue Medic in Rogue Medic

Imagine a system where we intentionally ignore the usual horribly inaccurate trauma triage criteria, such as MOI (Mechanism Of Injury). And these are not even the usual criteria, because this is in a system with criteria already modifieded to avoid a lot of overtriage. :-)... Read more »

Some notes on the Atlantic cod genome, and fish genomes in general

by Daniel in Ego sum Daniel

Teleost fish genome sequences have been absolutely essential to our understanding of vertebrate genome evolution, and to vertebrate evolution in general. Last month I welcomed the addition of the Atlantic cod genome to the sequenced fish genomes, and highlighted some of the main findings of the first analysis of the whole genome sequence. The preliminary genome database is now available for browsing at the Pre!Ensembl database.

After I had written that post, I had some notes left over becaus........ Read more »

For a realistic Milky Way simulation, just add clustered star formation

No Blank Slate (Part 2): In Closing, Treat Your Jurors as Instrumental Arguers

by Persuasion Strategies in Persuasive Litigator

Your case has finally gone to the jury, and the panel is now ensconced in the jury room. What are they doing in there? Are they carefully and logically arguing the merits of your case, considering all sides until the truth wins out? If you have ever watched a closed-circuit feed of mock jury deliberations, or talked in detail with actual jurors after a verdict, you know the answer is, "No, not really doing that." What they are likely doing instead is using argument instrumentally, as a tool ........ Read more »

FUTON Bias. Or Why Limiting to Free Full Text Might not Always be a Good Idea.

by Laika in Laika's Medliblog

A few weeks ago I was discussing possible relevant papers for the Twitter Journal Club  (Hashtag #TwitJC), a succesful initiative on Twitter, that I have discussed previously here and here [7,8]. I proposed an article, that appeared behind a paywall. Annemarie Cunningham (@amcunningham) immediately ran the idea down, stressing that open-access (OA) is a pre-requisite for the TwitJC [...]...

Does Diminished Work Activity Explain Our 50-Year Overweight Trend?

by Steve Parker, M.D. in Advanced Mediterranean Diet

Daily work-related energy expenditure over the last half-century in the U.S. has decreased by over 100 calories.  This may well explain the increase in body weights we’ve seen, according to a 2011 article in PLoS ONE.
I sorta hate to open this can o’ worms, but it’s important.  As a population, are we fat because we eat too much [...]... Read more »

Can Hyenas Count?

by Jim Ryan in Wild Mammals

During a pivotal scene in West Side Story, the Jets and the Sharks meet to prepare to rumble. As the gangs assembled each side likely tried to assess their opponent’s strength. This ability to assess numerical advantage is highly advantageous in any species where conflict between groups is common.

Spotted hyenas (Crocuta crocuta) live in large fission-fussion clans where smaller groups often forage separately (Figure 1). The composition and size of these subgroups varies over time ........ Read more »

Satellite cells muscle their way into the stem cell spotlight

by Erin Campbell in the Node

Researchers have long known about regeneration of injured muscles, and have debated about the exact source of the muscle stem cells that perform this amazing feat.  A group of papers in a recent issue of Development shine a stem cell spotlight on satellite cells. Following injury, skeletal muscles are regenerated by muscle stem cells, but [...]... Read more »

Filtering Blood During Cardiopulmonary Bypass (CPB)

by Hector Munoz in Microfluidic Future

Cardiopulmonary BypassCardiopulmonary Bypass (source)            More than 1,000 adult and 50 pediatric patients undergo a surgery involving cardiopulmonary bypass (CPB) each day in the United States. A CPB is used when performing surgery on the heart or lungs, leaving them unable to perform their normal functions. But CPB introduces a lot of foreign material to the body, creating adverse reactions. The CPB assembly, drugs and surgical processes can each have t........ Read more »

So after lab meeting, I’m going to grab a drink at the plus end of a microtubule. I hear it’s a swingin’ place, with lots of cool things going on. I also hear a kinesin-8 is a real mover and shaker at the plus end, but you’ll have to check out today’s image to see for yourself.

The structure and function of the mitotic spindle depends on the amazing qualities of microtubules. Microtubules grow and shorten from their plus ends (mostly), which are the ends that reach out towards the........ Read more »

Gene fusions in colorectal cancer

The NeuroSocial Network

by Dario Dieguez, Jr, PhD in Brain Blogger

Social neuroscience is a rapidly growing discipline that examines the relationship between the brain and social behavior. The “social brain hypothesis” posits that, over evolutionary time, living in large, social groups favored the physical growth of brain regions important for social behavior. In non-human primates, some evidence indicates that the size of the amygdala is [...]... Read more »

A 25-pound rattlesnake in South Carolina? Unlikely.

by David Steen in Living Alongside Wildlife

The reportedly 5.5 foot long, 25 pound rattlesnake
This morning I was made aware of a large Eastern Diamondback Rattlesnake that had been captured on Hilton Head Island in South Carolina. This in itself isn't too surprising, the species can range up to North Carolina and are often found on barrier islands. Although, there isn't much habitat left for snakes on these islands because they are ... Read more »

Man-made meat: hard to stomach?

by NerdyOne in Try Nerdy

I love eating meat. It’s no secret that I would probably be strictly carnivorous if it were just as easy to whip up a half-rack of ribs as it is to pour a bowl of cereal. Alas, meat preparation can be relatively involved, so I don’t eat it with every meal. But I do get what I call “protein deprivation” headaches if I have to go more than, say, 24 hours without meat.

All of this is to say that I have a vested interest in knowing I have a reliable supply of meat of avail........ Read more »
