Acinetobacter baumannii the most opportunisitic-ist pathogen you know

by James Byrne in Disease Prone

A. baumannii does not mess around. As opportunistic pathogens go it’s pretty out there. An aerobic, gram negative, almost entirely antibiotic resistant (largely through passive mechanisms) bacterium that’s developing such a terrible reputation that it has picked up the nickname ‘Iraqibacter’, but that’s mostly because of the high proportion of A. baumannii infections in returned American troops....

Coming to terms with the female orgasm

by Greg Laden in Greg Laden's Blog

I think I know why science does not understand the female orgasm. It is because science excels when it breaks free of context, history, human complexities and anthropology, but when a topic requires one to grasp context, history, human complexities and anthropology, then science, especially the hard sciences, can fall short. Also, the nature of the female orgasm is a comparative question, but human sexuality is highly (but not entirely) derived; It is difficult to make a sensible graph or tabl........ Read more »

Histones Signal Other Proteins Too

by Chris Womack in E3 Engaging Epigenetics Experts

Here’s an epigenetics first.

It turns out that intermolecular signaling in epigenetics — all that ubiquination, methylation, and so forth — doesn’t always end at DNA or histones, where those two components go on just to regulate genes (or to encourage more modification of themselves and each other). Nope, John Latham and colleagues at the University of Texas M.D. Anderson Cancer Center reported in Cell last week that there’s at least one case — in yeast &md........ Read more »

More about the Gila Cliff Dwellings

by teofilo in Gambler's House

Despite their impressive preservation, the Gila Cliff Dwellings have gotten surprisingly little attention in the archaeological literature.  This is apparently because they were so thoroughly ransacked by pothunters early on that there wasn’t much left intact for archaeologists to study, and possibly also because the early establishment of Gila Cliff Dwellings National Monument in 1907 [...]...

What’s most helpful for improving performance – precise or vague information?

by pennydeck in Feedback Solutions for Obesity

How precise does feedback need to be in order to support behaviour change? Most of us prefer exact information and are adverse to ambiguity (1), but absolute values may not be as successful for supporting behaviour change as one might … Continue reading →... Read more »

Chengjiang

by Marc in Teaching Biology

One of the highlighted Konservat-Lagerstätten in my Rise of Animals post is Chengjiang (a.k.a. the Maotianshan Shales). While Burgess has the historical significance, in terms of importance and potential, Chengjiang is arguably more important (see Shu, 2008). Chengjiang fossils are not the easiest to see, although they are admittedly abundant, at 40000+ specimens so far. [...]... Read more »

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

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

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 »

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.

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

Following injury, skeletal muscles are regenerated by muscle stem cells, but [...]... Read more »
